Role of Fluid Couplings in Heavy-Duty Mining Equipment

Fluid couplings play a critical role in heavy-duty mining equipment, offering several advantages that enhance the performance, safety, and longevity of the machinery:

  • Soft Start: In mining applications, where large equipment like crushers, conveyors, and draglines are involved, fluid couplings provide a soft start to the motor, gradually ramping up the torque and reducing the shock and stress on the drivetrain. This ensures smoother equipment startup and prevents sudden power demand spikes.
  • Torque Limiting: Fluid couplings act as torque limiters, protecting the equipment from sudden overloads and torque surges during operations. This feature prevents damage to the motor, gearbox, and driven components, thus increasing the reliability and lifespan of the equipment.
  • Load Distribution: In mining equipment with multiple driven components or motors, fluid couplings enable efficient load distribution among the components. This ensures that each component shares the load appropriately, preventing uneven wear and improving overall system efficiency.
  • Overload Protection: The inherent slip feature of fluid couplings allows them to slip at high loads, providing overload protection to the equipment. In case of unexpected jams or blockages in conveyor belts or crushers, the fluid coupling can slip, preventing costly damage to the equipment.
  • Vibration Damping: Mining operations can generate significant vibrations that can be damaging to the equipment. Fluid couplings help dampen vibrations, reducing stress on the components and minimizing wear and tear.
  • Reduced Maintenance: By preventing sudden torque surges and overloads, fluid couplings reduce the need for frequent maintenance and repairs, saving both time and money for mining operators.

Heavy-duty mining equipment operates in harsh and challenging environments with high loads and abrasive materials. Fluid couplings used in mining applications are designed to be robust, durable, and resistant to contaminants like dust and water.

Overall, fluid couplings play a vital role in ensuring the efficient and reliable operation of heavy-duty mining equipment, contributing to increased productivity and reduced downtime in mining operations.

Fluid Couplings for Soft-Start Applications in Conveyor Systems

Yes, fluid couplings are well-suited for soft-start applications in conveyor systems. Soft-starting is the gradual acceleration of the conveyor belt to reduce sudden mechanical stress and current spikes during startup. Fluid couplings provide a smooth and controlled method of power transmission, making them ideal for achieving soft-start capabilities in conveyor systems.

When a conveyor system equipped with a fluid coupling starts, the fluid inside the coupling initially acts as a viscous medium, allowing the input and output shafts to rotate at different speeds. As the fluid coupling fills with fluid, it gradually transmits torque and smoothly accelerates the conveyor belt.

One of the significant advantages of using fluid couplings for soft-start applications is that they provide adjustable startup times. By controlling the amount of fluid inside the coupling, the startup acceleration rate can be precisely tuned to match the specific requirements of the conveyor system.

The soft-start feature offered by fluid couplings helps in several ways:

  • Mechanical Stress Reduction: The gradual acceleration minimizes mechanical stress on the conveyor belt, pulleys, and other components, leading to extended equipment life and reduced maintenance costs.
  • Energy Savings: Soft-starting prevents sudden current spikes and reduces the power demand during startup, resulting in energy savings and improved efficiency.
  • Improved Conveyor Belt Life: By avoiding abrupt starts, the wear and tear on the conveyor belt are reduced, leading to longer belt life and decreased downtime.
  • Enhanced Conveyor Control: Soft-start capabilities enable better control over the conveyor system, allowing operators to optimize the material flow and prevent product spillage or jamming.

Fluid couplings offer reliable and cost-effective soft-start solutions for conveyor systems across various industries, including mining, manufacturing, and material handling. They are particularly beneficial when dealing with heavy loads or long conveyor belts, where the avoidance of sudden shock loads is critical.

In summary, fluid couplings are a popular choice for soft-start applications in conveyor systems due to their smooth and controlled power transmission, adjustable startup times, and the ability to reduce mechanical stress and energy consumption during startup.

Use of Fluid Couplings in Horizontal and Vertical Shaft Arrangements

Yes, fluid couplings can be used in both horizontal and vertical shaft arrangements, providing flexible power transmission solutions for various industrial applications.

1. Horizontal Shaft Arrangements:

In horizontal shaft arrangements, the fluid coupling is installed between the driving and driven shafts, which are positioned horizontally and parallel to each other. The fluid coupling allows torque to be transmitted smoothly from the driving shaft to the driven shaft, enabling the machinery or equipment to start up gradually without abrupt shocks or overloading. This feature is especially beneficial in applications where heavy loads need to be accelerated smoothly, such as conveyors, crushers, and pumps.

2. Vertical Shaft Arrangements:

In vertical shaft arrangements, the fluid coupling is used to connect the driving and driven shafts, which are positioned vertically and aligned on top of each other. The fluid coupling allows for torque transmission and controlled acceleration, just like in horizontal arrangements. Vertical shaft fluid couplings are commonly used in applications such as vertical conveyors, hoists, and elevators, where they provide smooth starting and stopping of the equipment, preventing sudden jolts and reducing stress on the machinery.

Fluid couplings offer versatility in power transmission and are adaptable to various shaft arrangements, making them suitable for a wide range of industrial setups. Whether the application involves horizontal or vertical shafts, fluid couplings play a crucial role in enhancing the performance, safety, and efficiency of power transmission systems.

A flexible shaft chain coupling connects 2 shafts in a rotating system. It is designed to provide a loose connection between the shafts, allowing for misalignment or axial movement.

The flexible shaft chain coupling consists of 2 hubs connected by a chain or series of links. The hubs are typically made from steel or aluminum and are designed to fit CHINAMFG the shafts to be connected. The chain or links provide the flexibility to accommodate misalignment or axial movement between the posts.

Flexible shaft chain couplings are commonly used in applications with misalignment or axial movement between the shafts, such as pumps, compressors, or generators. They can also help absorb shock and vibration in the system, which can help protect the equipment and reduce maintenance costs.

One of the advantages of flexible shaft chain couplings is their ability to transmit torque between the 2 shafts while allowing for some misalignment or axial movement. They are also relatively easy to install and maintain and can be used in various industrial applications.

Handling Overloads and Stall Conditions in Fluid Couplings

A fluid coupling is designed to handle overloads and stall conditions in power transmission systems. When an overload or stall occurs, the fluid coupling utilizes its unique operating principle to protect the drivetrain and the connected machinery:

  • Slip Feature: One of the key characteristics of a fluid coupling is its ability to slip at high torque loads. When an overload situation arises, the fluid coupling allows some relative motion between the input and output sides, known as slip. This slip absorbs the excess torque and prevents it from being transferred to the driven equipment, effectively protecting it from damage.
  • Fluid Circulation: During normal operation, the fluid inside the coupling circulates smoothly between the impeller and turbine, transmitting torque with minimal losses. However, when an overload or stall condition occurs, the fluid circulation may become turbulent, generating heat in the process. This heat dissipation helps in absorbing and dissipating the excess energy, preventing the transmission system from experiencing sudden stress.
  • Automatic Reconnection: After an overload or stall condition, once the excess torque is dissipated through slip and heat, the fluid coupling automatically reconnects the input and output sides, resuming the power transmission. This automatic reconnection ensures that the system returns to normal operation once the overload situation is resolved.
  • Sturdy Construction: Fluid couplings are designed with robust and durable materials to withstand high torque and thermal stresses during overload conditions. The strong construction ensures that the fluid coupling remains reliable and operational even after multiple overload events.

Overall, a fluid coupling’s ability to handle overloads and stall conditions makes it a reliable and essential component in various industrial applications. By providing overload protection and slip characteristics, fluid couplings help prevent costly damage to equipment, increase operational safety, and contribute to the longevity of the entire power transmission system.

Special Considerations for Using Fluid Couplings in Explosive Environments

Fluid couplings are widely used in various industrial applications, including those in potentially explosive environments. When considering the use of fluid couplings in such settings, several special considerations must be taken into account to ensure safety and compliance with regulations:

  • Explosion-Proof Design: Fluid couplings used in explosive environments must be designed to prevent the ignition of flammable gases or vapors. They should adhere to explosion-proof standards and be equipped with robust seals and protective enclosures to contain any potential sparks or flames.
  • Ingress Protection: An appropriate ingress protection (IP) rating is essential to prevent dust, moisture, or other hazardous substances from entering the fluid coupling. A higher IP rating ensures greater protection against potential sources of ignition.
  • Material Selection: The choice of materials for the fluid coupling is crucial in explosive environments. Non-sparking or anti-static materials should be used to reduce the risk of ignition caused by friction or electrical discharge.
  • Temperature Limitations: Fluid couplings operating in explosive environments must have temperature ratings that prevent overheating and potential ignition of flammable substances. The fluid coupling should be adequately cooled to maintain safe operating temperatures.
  • Monitoring and Maintenance: Regular monitoring and maintenance of fluid couplings in explosive environments are essential. Periodic inspections can detect potential issues or wear that could compromise the safety of the coupling. Any maintenance or repair work should be carried out by qualified personnel following safety protocols.
  • Compliance with Regulations: Depending on the industry and location, there may be specific regulations and safety standards that govern the use of equipment in explosive atmospheres. It is crucial to adhere to these regulations and ensure that the fluid coupling complies with all relevant safety requirements.

Fluid couplings used in explosive environments play a vital role in ensuring the safe and reliable operation of industrial machinery. By providing smooth and controlled power transmission, fluid couplings can help minimize risks and improve the overall safety of the equipment and personnel in these hazardous settings.

Before implementing fluid couplings in explosive environments, it is essential to conduct a thorough risk assessment and consult with experts familiar with the specific safety requirements of the industry. By taking appropriate safety measures and selecting suitable explosion-proof fluid couplings, the risks associated with using power transmission equipment in hazardous areas can be effectively mitigated.

Product Description

Stainless Steel Coupling Gear Rigid Roller Chain Fluid Tyre Grid Jaw Spider HRC Nm Motor Flange Gear Pump Rubber Spline Shaft Flexible Universal Joint Coupling

Product Description

Main products
Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.

Couplings can be divided into rigid couplings and flexible couplings.
Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.
Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. However, due to the strength of elastic elements, the transmitted torque is generally inferior to that of flexible couplings without elastic elements. Common types include elastic sleeve pin couplings, elastic pin couplings, quincunx couplings, tire type couplings, serpentine spring couplings, spring couplings, etc

Coupling performance

1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CHINAMFG requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.

How to select the appropriate coupling type

The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

Contribution of Fluid Coupling to the Longevity of Connected Equipment

A fluid coupling plays a crucial role in enhancing the longevity and protecting the connected equipment by providing the following benefits:

  • Shock Load Damping: When the equipment starts or stops, there can be sudden changes in torque, resulting in shock loads. The fluid coupling absorbs and dampens these shock loads, reducing stress and wear on the connected equipment.
  • Torsional Vibration Damping: Torsional vibrations can occur during the operation of the connected equipment, which can be damaging over time. The fluid coupling acts as a torsional damper, reducing these vibrations and preventing potential fatigue failure in the equipment.
  • Overload Protection: In case of sudden overloads or jamming of the connected equipment, the fluid coupling can slip and decouple the load, protecting both the equipment and the driving motor from excessive stress and damage.
  • Smooth Startup: During startup, the fluid coupling allows a gradual increase in torque, enabling a smooth and controlled acceleration of the connected equipment. This eliminates sudden jerks and reduces mechanical stress during the startup phase.
  • Load Distribution: The fluid coupling distributes the load evenly across the connected equipment, minimizing wear and tear on specific components and extending the overall lifespan of the machinery.
  • Reduced Maintenance: By reducing shock loads and vibrations, the fluid coupling helps decrease the frequency of maintenance and repairs required for the connected equipment, resulting in cost savings and improved uptime.
  • Energy Efficiency: The fluid coupling allows for efficient power transmission by reducing losses during startup and load changes. This, in turn, helps in lowering the overall energy consumption of the system and contributes to equipment longevity.
  • Contamination Prevention: The fluid coupling encapsulates the driving and driven components, providing a barrier that helps prevent contaminants such as dust, dirt, and moisture from entering the equipment’s internal components. This protection can extend the life of bearings and other sensitive parts.

Overall, a fluid coupling acts as a protective intermediary between the driving motor and the connected equipment, enhancing the system’s reliability, efficiency, and longevity by mitigating the effects of shocks, vibrations, and overloads.

Real-World Case Studies: Improved Performance with Fluid Couplings

Fluid couplings have been widely adopted in various industries, and numerous real-world case studies demonstrate their positive impact on performance and efficiency. Here are a few examples:

Case Study 1: Mining Conveyor System

In a large mining operation, a conveyor system used to transport heavy loads of ore experienced frequent starts and stops due to fluctuating material supply. The abrupt starting and stopping led to significant wear and tear on the conveyor components, causing frequent breakdowns and maintenance downtime.

After installing fluid couplings at critical points in the conveyor system, the soft start and stop capability of the fluid couplings significantly reduced the mechanical stress during operation. This led to a smoother material flow, reduced conveyor wear, and extended equipment life. Additionally, the fluid couplings’ overload protection feature prevented damage to the conveyor during peak loads, ensuring uninterrupted production.

Case Study 2: Marine Propulsion System

In a marine vessel equipped with traditional direct drive systems, the crew faced challenges in maneuvering the ship efficiently. The fixed propeller arrangement made it challenging to control the vessel’s speed and direction accurately, leading to increased fuel consumption and decreased maneuverability.

By retrofitting the vessel’s propulsion system with fluid couplings, the ship’s performance improved significantly. The fluid couplings allowed for flexible and smooth speed control, enabling precise maneuvering and reduced fuel consumption. The ability to adjust the load on the propeller enhanced the vessel’s overall efficiency, resulting in reduced operating costs and improved environmental sustainability.

Case Study 3: Industrial Pumping Station

In an industrial pumping station, the constant starting and stopping of the pumps caused water hammer and pressure surges within the pipeline network. The sudden hydraulic shocks led to pipe bursts, valve failures, and increased energy consumption.

After implementing fluid couplings in the pump drive systems, the pumps could be softly started and stopped. The fluid couplings’ torque control capabilities ensured a gradual increase in pump speed, eliminating water hammer and pressure surges. As a result, the pumping station’s reliability improved, maintenance costs decreased, and the energy consumption reduced due to smoother pump operations.

These case studies demonstrate the positive effects of using fluid couplings in various applications. They highlight how fluid couplings contribute to improved performance, reduced mechanical stress, enhanced control, and cost savings in industrial machinery and systems.

Fluid Couplings and Energy Efficiency in Power Transmission

Fluid couplings play a significant role in improving energy efficiency in power transmission systems. They achieve this by enabling smooth and efficient torque transmission while reducing energy losses during various operating conditions.

One of the key factors contributing to the energy efficiency of fluid couplings is their hydrodynamic principle of operation. When power is transmitted through a fluid coupling, it operates on the principle of hydrodynamic power transmission. The primary component, known as the impeller, rotates and imparts motion to the fluid inside the coupling. This motion creates a hydrodynamic force that transmits the torque to the output side.

During the initial startup or when there is a significant speed difference between the input and output shafts, the fluid coupling allows the input shaft to accelerate gradually. This feature, known as the soft start, reduces the mechanical stress on the connected components and the power source. By avoiding sudden acceleration, fluid couplings minimize the energy spikes that occur during direct starts in systems without couplings.

Moreover, fluid couplings act as a torque limiter when the load exceeds a certain threshold. This characteristic, known as the slip, allows the fluid coupling to disengage slightly when the torque reaches a predetermined level. As a result, it protects the system from overloads and reduces energy wastage during high-stress conditions.

Additionally, fluid couplings help mitigate the impact of shock loads and torsional vibrations, which can reduce wear and tear on mechanical components. By minimizing vibrations and shock loads, fluid couplings contribute to longer equipment life and, consequently, lower maintenance and replacement costs.

However, it’s important to note that like any mechanical component, fluid couplings have some energy losses due to viscous drag and heat dissipation. While modern fluid couplings are designed with improved efficiency, these losses need to be considered when assessing the overall energy efficiency of a power transmission system.

In summary, fluid couplings enhance energy efficiency in power transmission by providing soft starts, torque limiting, and damping of vibrations, thus reducing energy wastage and extending the life of the connected equipment.

fluid coupling

Fluid Coupling and Smooth Power Transmission during Starting and Stopping

A fluid coupling is designed to facilitate smooth power transmission during the starting and stopping phases of machinery and equipment. It achieves this by utilizing the principle of hydrodynamic torque transmission through a fluid medium.

Starting Phase: When power is initially supplied to the input shaft of the fluid coupling, the impeller (also known as the pump) begins to rotate, imparting energy to the fluid inside the coupling. As the fluid gains kinetic energy, it starts moving outward towards the turbine (also called the driven element) due to centrifugal force.

The kinetic energy of the moving fluid causes the turbine to start rotating, transmitting torque to the output shaft. During this starting phase, there is a slight time lag, known as the “slip,” between the impeller and the turbine. However, as the fluid coupling reaches its operational speed, the slip reduces, and the turbine matches the speed of the impeller, resulting in smooth power transmission from the input to the output shaft.

The fluid coupling’s ability to control the slip ensures a gradual and controlled acceleration of the driven equipment, minimizing stress on the drivetrain components and preventing sudden shock loads.

Stopping Phase: When power to the input shaft is reduced or cut off, the impeller slows down, and the kinetic energy in the fluid decreases. As a result, the fluid moves away from the turbine towards the center of the coupling, reducing the torque transmission between the input and output shafts.

This characteristic of the fluid coupling aids in smoothly decelerating the connected equipment, preventing sudden jolts or jerks during the stopping process. The ability to control the slip during deceleration ensures that the driven machinery comes to a gradual and controlled stop, enhancing safety and protecting the equipment from damage.

The combination of hydrodynamic torque transmission and the ability to control the slip makes fluid couplings ideal for applications where smooth power transmission during starting and stopping is essential. Industries such as mining, construction, metal processing, marine propulsion, and power generation benefit from the reliable and efficient performance of fluid couplings in various machinery and equipment.

Role of Fluid Coupling in Reducing Mechanical Stress on Connected Equipment

A fluid coupling is a mechanical device used to transmit power between two shafts without direct physical contact. It plays a crucial role in reducing mechanical stress on connected equipment, offering several benefits in various industrial applications. Here’s how a fluid coupling achieves this:

  • Smooth Power Transmission: Fluid couplings use hydraulic principles to transmit torque. When the input shaft (driving shaft) rotates, it imparts motion to the fluid inside the coupling. The fluid transmits torque to the output shaft (driven shaft) through the hydraulic coupling, resulting in smooth and gradual power transmission. This eliminates sudden jerks and mechanical shocks that could otherwise lead to increased stress on connected equipment.
  • Damping Effect: Fluid couplings act as a damping element, absorbing vibrations and torsional oscillations from the driving shaft. This damping effect helps reduce mechanical stress on connected equipment by mitigating the impact of sudden load changes and torsional vibrations that may occur during start-ups, shut-downs, or varying operating conditions.
  • Torque Limiting: In high-load situations, a fluid coupling can provide torque limiting capabilities. When the load exceeds a certain threshold, the fluid coupling slips, preventing excessive torque from reaching the driven shaft. This feature acts as a protective mechanism, preventing overloading and mechanical stress on both the coupling and connected equipment.
  • Shock Absorption: In applications where shock loads or overloads are common, a fluid coupling can absorb and dampen the impact of such events. This ability to cushion shocks prevents abrupt changes in torque and rotational speed, reducing mechanical stress and potential damage to the equipment.
  • Speed Control: In certain applications, fluid couplings can facilitate speed control of the driven shaft by adjusting the amount of fluid in the coupling. The ability to control the speed of connected equipment without abrupt changes contributes to smoother operation and lower mechanical stress.

By incorporating a fluid coupling into a power transmission system, mechanical stress on connected equipment can be significantly reduced, leading to improved equipment reliability, extended component life, and reduced maintenance costs. Fluid couplings are commonly used in heavy machinery, conveyors, crushers, mining equipment, marine propulsion systems, and various other industrial applications where smooth and controlled power transmission is critical.

It is important to select the appropriate fluid coupling size, type, and features based on the specific application requirements to ensure optimal performance and stress reduction. Regular maintenance and adherence to the manufacturer’s guidelines are essential to preserve the benefits of using fluid couplings and maintain their effectiveness in reducing mechanical stress on connected equipment.

Comparison: Fluid Coupling vs. Torque Converter

Fluid couplings and torque converters are both hydrodynamic devices used in automotive and industrial applications to transmit power between an engine and a driven load. While they share some similarities, they also have distinct differences:

  • Function: The primary function of both fluid couplings and torque converters is to transmit rotational power from the engine to the transmission or driven load. They allow for smooth power transmission and provide a degree of isolation between the engine and the load.
  • Construction: Both devices consist of an impeller, a turbine, and a housing filled with hydraulic fluid (usually oil). The impeller is connected to the engine’s crankshaft, the turbine to the transmission/input shaft, and the housing is shared between the two.
  • Torque Transmission: In a fluid coupling, the power is transmitted purely through hydrodynamic principles. The impeller accelerates the fluid, which then drives the turbine. However, there is no torque multiplication, and the output speed is always slightly less than the input speed. On the other hand, a torque converter can provide torque multiplication due to its stator, which redirects the fluid flow and increases the torque transmitted to the turbine.
  • Lock-up Clutch: Some torque converters have a lock-up clutch that can mechanically connect the impeller and the turbine at higher speeds. This effectively eliminates the slip between the two elements and increases overall efficiency, similar to the operation of a fluid coupling at higher speeds.
  • Automotive Use: Torque converters are commonly used in automatic transmissions in vehicles, while fluid couplings were more prevalent in older manual transmissions. However, modern manual transmissions generally use clutch systems instead of fluid couplings.
  • Efficiency: Fluid couplings are generally more efficient than torque converters, especially at higher speeds. Torque converters can experience efficiency losses due to fluid slippage and the operation of the stator.
  • Applications: Fluid couplings find applications in various industrial machinery, such as conveyors, pumps, and crushers, where the priority is smooth power transmission and overload protection. Torque converters are primarily used in vehicles, offering the benefit of automatic gear shifting and torque multiplication during acceleration.

Overall, both fluid couplings and torque converters play essential roles in power transmission, but their specific design and application characteristics determine their suitability for different use cases.

Product Description

Stainless Steel Coupling Gear Rigid Roller Chain Fluid Tyre Grid Jaw Spider HRC Nm Motor Flange Gear Pump Rubber Spline Shaft Flexible Universal Joint Coupling

Product Description

Main products
Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.

Couplings can be divided into rigid couplings and flexible couplings.
Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.
Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. However, due to the strength of elastic elements, the transmitted torque is generally inferior to that of flexible couplings without elastic elements. Common types include elastic sleeve pin couplings, elastic pin couplings, quincunx couplings, tire type couplings, serpentine spring couplings, spring couplings, etc

Coupling performance

1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CHINAMFG requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.

How to select the appropriate coupling type

The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

Handling Overloads and Stall Conditions in Fluid Couplings

A fluid coupling is designed to handle overloads and stall conditions in power transmission systems. When an overload or stall occurs, the fluid coupling utilizes its unique operating principle to protect the drivetrain and the connected machinery:

  • Slip Feature: One of the key characteristics of a fluid coupling is its ability to slip at high torque loads. When an overload situation arises, the fluid coupling allows some relative motion between the input and output sides, known as slip. This slip absorbs the excess torque and prevents it from being transferred to the driven equipment, effectively protecting it from damage.
  • Fluid Circulation: During normal operation, the fluid inside the coupling circulates smoothly between the impeller and turbine, transmitting torque with minimal losses. However, when an overload or stall condition occurs, the fluid circulation may become turbulent, generating heat in the process. This heat dissipation helps in absorbing and dissipating the excess energy, preventing the transmission system from experiencing sudden stress.
  • Automatic Reconnection: After an overload or stall condition, once the excess torque is dissipated through slip and heat, the fluid coupling automatically reconnects the input and output sides, resuming the power transmission. This automatic reconnection ensures that the system returns to normal operation once the overload situation is resolved.
  • Sturdy Construction: Fluid couplings are designed with robust and durable materials to withstand high torque and thermal stresses during overload conditions. The strong construction ensures that the fluid coupling remains reliable and operational even after multiple overload events.

Overall, a fluid coupling’s ability to handle overloads and stall conditions makes it a reliable and essential component in various industrial applications. By providing overload protection and slip characteristics, fluid couplings help prevent costly damage to equipment, increase operational safety, and contribute to the longevity of the entire power transmission system.

Fluid Couplings in High-Temperature Environments

Fluid couplings are versatile power transmission devices commonly used in various industrial applications. However, their suitability for high-temperature environments depends on several factors, including the design, materials, and the specific operating conditions.

Here are some key considerations regarding the use of fluid couplings in high-temperature environments:

  • Fluid Type: The type of fluid used inside the coupling greatly influences its temperature capabilities. Some fluid couplings are designed to handle higher temperatures by using specially formulated high-temperature fluids that can withstand elevated heat levels without degradation.
  • Materials: The materials used in the construction of the fluid coupling play a crucial role in determining its maximum temperature tolerance. High-quality materials with good heat resistance properties are required to ensure reliable performance in high-temperature conditions.
  • Lubrication: Proper lubrication is essential to reduce friction and heat generation within the fluid coupling. In high-temperature environments, ensuring sufficient and appropriate lubrication is crucial to prevent excessive wear and potential damage.
  • Cooling: Some fluid couplings come equipped with cooling systems, such as cooling fins or external cooling circuits, to dissipate excess heat generated during operation. These cooling mechanisms can enhance the coupling’s capacity to handle higher temperatures.
  • Application Considerations: The specific application and load requirements must be taken into account. In some cases, high-temperature conditions may be intermittent or occasional, allowing the fluid coupling to cool down between cycles. However, continuous high-temperature operation may require a more robust and specialized fluid coupling.

It is important to consult with the fluid coupling manufacturer to understand the temperature limitations and performance capabilities of their products. Manufacturers can provide guidance on selecting the appropriate fluid coupling for specific high-temperature applications.

While fluid couplings can be suitable for moderate to high-temperature environments, it is essential to operate them within their specified temperature range to ensure optimal performance and longevity. Extreme temperatures beyond the coupling’s rated limits can lead to accelerated wear, reduced efficiency, and potential damage, ultimately affecting the reliability of the power transmission system.

In summary, fluid couplings can be used in high-temperature environments, provided that the coupling’s design, materials, and lubrication are suitable for the specific application and operating conditions. Regular maintenance and adherence to the manufacturer’s guidelines are essential to ensure reliable performance and durability in such environments.

fluid coupling

Controlling Torque and Rotational Speed with Fluid Couplings

A fluid coupling plays a crucial role in controlling torque and rotational speed in power transmission systems. The principle behind its operation allows for smooth torque transmission while offering some level of speed control:

  • Torque Transmission: When power is applied to the input side (also known as the driving side) of the fluid coupling, the impeller starts to rotate and accelerates the transmission fluid inside the housing. The kinetic energy of the moving fluid creates a rotating flow pattern that transfers torque to the output side (also known as the driven side) of the coupling. This torque transfer enables the connected machinery or equipment to start smoothly without any shock loading.
  • Slip: In a fluid coupling, there is always a slight difference in speed between the input and output sides due to the viscous nature of the fluid. This speed difference is known as slip. The slip allows the fluid coupling to protect the connected components from sudden torque spikes and vibrations. If the output side experiences an abrupt load increase or jam, the slip absorbs the excess torque, preventing damage to the drivetrain.
  • Speed Control: While fluid couplings are not as efficient in speed control as variable-speed drives, they do offer some inherent speed control characteristics. The amount of slip in the fluid coupling affects the output speed relative to the input speed. By adjusting the fill level of the fluid coupling or using different fluid viscosities, it is possible to fine-tune the speed at which the output shaft rotates. However, it’s important to note that this speed control is limited compared to other speed control mechanisms.

Overall, fluid couplings provide a reliable and efficient means of controlling torque during power transmission. Their ability to dampen torsional vibrations and provide overload protection makes them suitable for various applications where smooth torque transfer and protection against shock loads are essential.

Cost Implications of Using Fluid Couplings in Comparison to Other Power Transmission Methods

The cost implications of using fluid couplings in power transmission depend on various factors, including the application requirements, the size of the system, and the operational conditions. While fluid couplings offer several advantages, they may have different cost considerations compared to other power transmission methods like mechanical clutches, VFDs (Variable Frequency Drives), and direct mechanical drives.

1. Initial Investment:

The initial cost of a fluid coupling can be higher than that of a mechanical clutch or a direct mechanical drive. Fluid couplings contain precision components, including the impeller and turbine, which can impact their initial purchase price.

2. Maintenance Costs:

Fluid couplings are generally considered to have lower maintenance costs compared to mechanical clutches. Mechanical clutches have wear and tear components that may require more frequent replacements, leading to higher maintenance expenses over time.

3. Energy Efficiency:

Fluid couplings are highly efficient in power transmission, especially during soft-start applications. Their ability to reduce shock loads and provide a smooth acceleration can result in energy savings and operational cost reductions.

4. Space and Weight:

Fluid couplings are usually more compact and lighter than some mechanical clutches, which can be advantageous in applications with space constraints or weight limitations.

5. Specific Application Considerations:

The suitability and cost-effectiveness of fluid couplings versus other power transmission methods can vary based on specific application requirements. For example, in soft-start applications, fluid couplings may be the preferred choice due to their ability to reduce mechanical stress and protect connected equipment.

6. Lifespan and Reliability:

While the initial cost of a fluid coupling might be higher, their longevity and reliability can lead to lower overall life cycle costs compared to other power transmission methods.

In conclusion, the cost implications of using fluid couplings in power transmission depend on the particular application and the total cost of ownership over the equipment’s lifespan. Although fluid couplings may have a higher initial investment, their long-term reliability, energy efficiency, and lower maintenance costs can make them a cost-effective choice in many industrial applications.

What is a Fluid Coupling and How Does It Work?

A fluid coupling is a type of hydraulic device used to transmit torque and power between two shafts without direct mechanical contact. It consists of three main components: the impeller, the turbine, and the housing. Fluid couplings are commonly used in various industrial applications, such as heavy machinery, conveyors, and automotive drivetrains.

Working Principle: The fluid coupling operates based on the principle of hydrodynamic power transmission. It uses a hydraulic fluid (usually oil) to transfer torque from the driving shaft (input) to the driven shaft (output).

1. Impeller: The impeller is mounted on the input shaft and is connected to the prime mover (e.g., an electric motor or an engine). When the prime mover rotates the impeller, it creates a swirling motion in the hydraulic fluid.

2. Turbine: The turbine is connected to the output shaft and is responsible for transmitting the torque to the driven system. The swirling motion of the hydraulic fluid generated by the impeller causes the turbine to rotate.

3. Fluid Filling: The area between the impeller and the turbine is filled with hydraulic fluid. As the impeller rotates, it creates a vortex in the fluid, which in turn causes the turbine to rotate.

4. Fluid Coupling Working: As the impeller and turbine are enclosed in the housing, the hydraulic fluid transfers rotational energy from the impeller to the turbine without any direct physical connection. The fluid coupling allows some slip between the impeller and the turbine, which enables smooth torque transmission, dampens shock loads, and provides overload protection.

5. Slip: Under normal operating conditions, there is a slight speed difference (slip) between the impeller and the turbine. This slip allows the fluid coupling to absorb shock loads and dampen vibrations, protecting the connected machinery from sudden jolts and overloads.

Fluid couplings are advantageous in applications where a gradual start-up and controlled acceleration are required. They provide a smoother and more flexible power transmission compared to direct mechanical couplings like gear couplings or belt drives.

However, it’s important to note that fluid couplings have some energy loss due to the slip, which can result in reduced efficiency compared to direct mechanical couplings like gear couplings or belt drives.

Contribution of Fluid Coupling to the Overall Efficiency of a Mechanical System

A fluid coupling plays a crucial role in improving the overall efficiency of a mechanical system, especially in applications where smooth power transmission, soft-starting, and torque control are essential. Here’s how a fluid coupling contributes to system efficiency:

1. Smooth Power Transmission:

Fluid couplings provide a smooth and gradual transfer of power from the driving to the driven machinery. The absence of direct mechanical contact between the input and output shafts reduces shock loads and vibrations, leading to less wear and tear on the connected equipment. This smooth power transmission results in increased system efficiency and reduced downtime.

2. Soft-Start Capability:

Fluid couplings offer soft-starting functionality, which is particularly beneficial for high-inertia or heavy-load applications. During startup, the fluid coupling allows the input shaft to gradually accelerate the output shaft, preventing sudden jerks or torque spikes. Soft-starting not only protects the mechanical components but also reduces energy consumption during the starting phase, contributing to overall efficiency.

3. Torque Control:

Fluid couplings enable precise control over the torque transmitted between the driving and driven machinery. By adjusting the fill level or using variable speed couplings, the torque output can be fine-tuned to match the requirements of the application. This feature ensures optimal performance and energy efficiency, especially in systems where torque demand varies during operation.

4. Overload Protection:

In case of sudden overloads or jamming of the driven machinery, the fluid coupling acts as a torque limiter. It will slip and absorb excess torque, protecting the mechanical system from damage. This overload protection not only safeguards the equipment but also contributes to the longevity and efficiency of the entire system.

5. Heat Dissipation:

Fluid couplings can absorb and dissipate heat generated during continuous operations. This heat dissipation capability prevents the system from overheating, ensuring consistent performance and avoiding thermal damage to the machinery. By maintaining proper operating temperatures, the fluid coupling aids in improving overall efficiency.

6. Energy Savings:

With its ability to reduce shock loads and provide smooth acceleration, a fluid coupling can help save energy during starting and stopping cycles. The elimination of mechanical shocks and vibrations reduces energy losses, resulting in higher overall energy efficiency.

In summary, a fluid coupling enhances the overall efficiency of a mechanical system by providing smooth power transmission, soft-start capability, precise torque control, overload protection, heat dissipation, and energy savings. Its contributions to reduced wear and tear, energy-efficient operations, and enhanced equipment lifespan make it a valuable component in various industrial applications.

Product Description

Stainless Steel Coupling Gear Rigid Roller Chain Fluid Tyre Grid Jaw Spider HRC Nm Motor Flange Gear Pump Rubber Spline Shaft Flexible Universal Joint Coupling

Product Description

Main products
Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.

Couplings can be divided into rigid couplings and flexible couplings.
Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.
Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. However, due to the strength of elastic elements, the transmitted torque is generally inferior to that of flexible couplings without elastic elements. Common types include elastic sleeve pin couplings, elastic pin couplings, quincunx couplings, tire type couplings, serpentine spring couplings, spring couplings, etc

Coupling performance

1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CZPT requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.

How to select the appropriate coupling type

The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

Handling Overloads and Stall Conditions in Fluid Couplings

A fluid coupling is designed to handle overloads and stall conditions in power transmission systems. When an overload or stall occurs, the fluid coupling utilizes its unique operating principle to protect the drivetrain and the connected machinery:

  • Slip Feature: One of the key characteristics of a fluid coupling is its ability to slip at high torque loads. When an overload situation arises, the fluid coupling allows some relative motion between the input and output sides, known as slip. This slip absorbs the excess torque and prevents it from being transferred to the driven equipment, effectively protecting it from damage.
  • Fluid Circulation: During normal operation, the fluid inside the coupling circulates smoothly between the impeller and turbine, transmitting torque with minimal losses. However, when an overload or stall condition occurs, the fluid circulation may become turbulent, generating heat in the process. This heat dissipation helps in absorbing and dissipating the excess energy, preventing the transmission system from experiencing sudden stress.
  • Automatic Reconnection: After an overload or stall condition, once the excess torque is dissipated through slip and heat, the fluid coupling automatically reconnects the input and output sides, resuming the power transmission. This automatic reconnection ensures that the system returns to normal operation once the overload situation is resolved.
  • Sturdy Construction: Fluid couplings are designed with robust and durable materials to withstand high torque and thermal stresses during overload conditions. The strong construction ensures that the fluid coupling remains reliable and operational even after multiple overload events.

Overall, a fluid coupling’s ability to handle overloads and stall conditions makes it a reliable and essential component in various industrial applications. By providing overload protection and slip characteristics, fluid couplings help prevent costly damage to equipment, increase operational safety, and contribute to the longevity of the entire power transmission system.

Fluid Couplings for Soft-Start Applications in Conveyor Systems

Yes, fluid couplings are well-suited for soft-start applications in conveyor systems. Soft-starting is the gradual acceleration of the conveyor belt to reduce sudden mechanical stress and current spikes during startup. Fluid couplings provide a smooth and controlled method of power transmission, making them ideal for achieving soft-start capabilities in conveyor systems.

When a conveyor system equipped with a fluid coupling starts, the fluid inside the coupling initially acts as a viscous medium, allowing the input and output shafts to rotate at different speeds. As the fluid coupling fills with fluid, it gradually transmits torque and smoothly accelerates the conveyor belt.

One of the significant advantages of using fluid couplings for soft-start applications is that they provide adjustable startup times. By controlling the amount of fluid inside the coupling, the startup acceleration rate can be precisely tuned to match the specific requirements of the conveyor system.

The soft-start feature offered by fluid couplings helps in several ways:

  • Mechanical Stress Reduction: The gradual acceleration minimizes mechanical stress on the conveyor belt, pulleys, and other components, leading to extended equipment life and reduced maintenance costs.
  • Energy Savings: Soft-starting prevents sudden current spikes and reduces the power demand during startup, resulting in energy savings and improved efficiency.
  • Improved Conveyor Belt Life: By avoiding abrupt starts, the wear and tear on the conveyor belt are reduced, leading to longer belt life and decreased downtime.
  • Enhanced Conveyor Control: Soft-start capabilities enable better control over the conveyor system, allowing operators to optimize the material flow and prevent product spillage or jamming.

Fluid couplings offer reliable and cost-effective soft-start solutions for conveyor systems across various industries, including mining, manufacturing, and material handling. They are particularly beneficial when dealing with heavy loads or long conveyor belts, where the avoidance of sudden shock loads is critical.

In summary, fluid couplings are a popular choice for soft-start applications in conveyor systems due to their smooth and controlled power transmission, adjustable startup times, and the ability to reduce mechanical stress and energy consumption during startup.

Types of Coupling

A coupling is a device used to join two shafts together and transmit power. Its primary function is to join rotating equipment and allows for some end movement and misalignment. This article discusses different types of coupling, including Magnetic coupling and Shaft coupling. This article also includes information on Overload safety mechanical coupling.

Flexible beam coupling

Flexible beam couplings are universal joints that can deal with shafts that are offset or at an angle. They consist of a tube with couplings at both ends and a thin, flexible helix in the middle. This makes them suitable for use in a variety of applications, from motion control in robotics to attaching encoders to shafts.
These couplings are made of one-piece materials and are often made of stainless steel or aluminium alloy. However, they can also be made of acetal or titanium. While titanium and acetal are less common materials, they are still suitable for high-torque applications. For more information about beam couplings, contact CZPT Components.
Flexible beam couplings come in a variety of types and sizes. W series couplings are good for general purpose applications and are relatively economical. Stainless steel versions have increased torque capacity and torsional stiffness. Flexible beam couplings made of aluminum are ideal for servo and reverse motion. They are also available with metric dimensions.
Flexible beam couplings are made of aluminum alloy or stainless steel. Their patented slot pattern provides low bearing load and high torsional rigidity. They have a long operational life. They also require zero maintenance and can handle angular offset. Their advantages outweigh the disadvantages of traditional beam couplings.

Magnetic coupling

Magnetic coupling transfers torque from one shaft to another using a magnetic field. These couplings can be used on various types of machinery. These types of transmissions are very useful in many situations, especially when you need to move large amounts of weight. The magnetic field is also very effective at reducing friction between the two shafts, which can be extremely helpful if you’re moving heavy items or machinery.
Different magnetic couplings can transmit forces either linearly or rotated. Different magnetic couplings have different topologies and can be made to transmit force in various geometric configurations. Some of these types of couplings are based on different types of materials. For example, a ceramic magnetic material can be used for applications requiring high temperature resistance.
Hybrid couplings are also available. They have a hybrid design, which allows them to operate in either an asynchronous or synchronous mode. Hysterloy is an alloy that is easily magnetized and is used in synchronous couplings. A synchronous magnetic coupling produces a coupled magnetic circuit.
Magnetic coupling is a key factor in many physical processes. In a crystal, molecules exhibit different magnetic properties, depending on their atomic configuration. Consequently, different configurations produce different amounts of magnetic coupling. The type of magnetic coupling a molecule exhibits depends on the exchange parameter Kij. This exchange parameter is calculated by using quantum chemical methods.
Magnetic couplings are most commonly used in fluid transfer pump applications, where the drive shaft is hermetically separated from the fluid. Magnetic couplings also help prevent the transmission of vibration and axial or radial loads through the drive shaft. Moreover, they don’t require external power sources, since they use permanent magnets.

Shaft coupling

A shaft coupling is a mechanical device that connects two shafts. The coupling is designed to transmit full power from one shaft to the other, while keeping the shafts in perfect alignment. It should also reduce transmission of shock loads. Ideally, the coupling should be easy to connect and maintain alignment. It should also be free of projecting parts.
The shaft couplings that are used in machines are typically made of two types: universal coupling and CZPT coupling. CZPT couplings are designed to correct for lateral misalignment and are composed of two flanges with tongues and slots. They are usually fitted with pins. The T1 tongue is fitted into flange A, while the T2 tongue fits into flange B.
Another type of shaft coupling is known as a “sliced” coupling. This type of coupling compensates for inevitable shaft misalignments and provides high torque. Machined slits in the coupling’s outer shell help it achieve high torsional stiffness and excellent flexibility. The design allows for varying engagement angles, making it ideal for many different applications.
A shaft coupling is an important component of any machine. Proper alignment of the two shafts is vital to avoid machine breakdowns. If the shafts are misaligned, extra force can be placed on other parts of the machine, causing vibration, noise, and damage to the components. A good coupling should be easy to connect and should ensure precise alignment of the shaft. Ideally, it should also have no projecting parts.
Shaft couplings are designed to tolerate a certain amount of backlash, but it must be within a system’s threshold. Any angular movement of the shaft beyond this angle is considered excessive backlash. Excessive backlash results in excessive wear, stress, and breakage, and may also cause inaccurate alignment readings. It is therefore imperative to reduce backlash before the shaft alignment process.

Overload safety mechanical coupling

Overload safety mechanical couplings are devices that automatically disengage when the torque applied to them exceeds a specified limit. They are an efficient way to protect machinery and reduce the downtime associated with repairing damaged machinery. The advantage of overload couplings is their fast reaction time and ease of installation.
Overload safety mechanical couplings can be used in a wide range of applications. Their automatic coupling mechanisms can be used on any face or edge. In addition, they can be genderless, incorporating both male and female coupling features into a single mechanism. This means that they are both safe and gender-neutral.
Overload safety couplings protect rotating power transmission components from overloads. Overload protection devices are installed on electric motors to cut off power if the current exceeds a certain limit. Likewise, fluid couplings in conveyors are equipped with melting plug elements that allow the fluid to escape when the system becomes too hot. Mechanical force transmission devices, such as shear bolts, are designed with overload protection in mind.
A common design of an overload safety mechanical coupling consists of two or more arms and hubs separated by a plastic spider. Each coupling body has a set torque threshold. Exceeding this threshold may damage the spider or damage the jaws. In addition, the spider tends to dampen vibration and absorb axial extension. This coupling style is nearly backlash free, electrically isolating, and can tolerate very little parallel misalignment.
A mechanical coupling may also be a universal joint or jaw-clutch coupling. Its basic function is to connect the driver and driven shafts, and limits torque transfer. These devices are typically used in heavy-duty industries, such as steel plants and rolling mills. They also work well with industrial conveyor systems.
