Product Description

Custom CNC Turning Machining  Spline Shaft Couplings Steering Shaft Coupler Oldham Coupling
 

Product Description

 

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. 

Our leading mainly including universal couplings, drum gear couplings, elastic couplings etc.

What are the Potential Limitations or Drawbacks of Using an Oldham Coupling?

While Oldham couplings offer numerous advantages, they also have some limitations and drawbacks that should be considered when selecting a coupling for a specific application:

1. Limited Misalignment Capacity: Oldham couplings can only accommodate small amounts of angular and axial misalignment between the shafts. They are not suitable for applications with high levels of misalignment as excessive misalignment can lead to premature wear and failure of the center disc.

2. Speed Limitations: Oldham couplings are generally not recommended for high-speed applications. The flexible center disc has a maximum speed limit, and exceeding this limit can cause the disc to fatigue and fail over time.

3. Temperature Sensitivity: The performance of Oldham couplings can be affected by temperature fluctuations. Extreme temperatures can impact the flexibility and integrity of the center disc material, leading to reduced coupling performance.

4. Backlash in High-Precision Systems: While Oldham couplings minimize backlash compared to some other couplings, they may still have some inherent clearance between the hubs and the center disc, leading to a slight amount of backlash. In ultra-high-precision systems, this slight backlash may be a concern.

5. Material Compatibility: The material used for the center disc must be chosen carefully to ensure compatibility with the specific application’s environment and the media being conveyed. Some aggressive chemicals or harsh environments may degrade the material over time.

6. Maintenance: Oldham couplings require periodic inspection and maintenance to ensure proper functioning. The center disc may wear out over time and need replacement, especially in applications with high torque or frequent start-stop cycles.

Despite these limitations, Oldham couplings remain a popular choice in many applications due to their vibration reduction, backlash minimization, and moderate misalignment compensation capabilities. However, it is essential to carefully assess the specific requirements of the application and consider the potential drawbacks before selecting an Oldham coupling.

How an Oldham Coupling Accommodates Misalignment Between Shafts

An Oldham coupling accommodates misalignment between shafts through its unique design, which consists of three main components:

  1. Two Hubs: Each hub is attached to the shaft of the connected equipment. The hubs have a series of slots around their circumference.
  2. Middle Block: The middle block fits between the two hubs and has perpendicular slots on its inner diameter. It connects the two hubs while allowing relative movement between them.

When the shafts experience angular or axial misalignment, the middle block slides within the slots of both hubs. The perpendicular slots on the middle block engage with the slots on the hubs, creating a parallelogram linkage.

This parallelogram linkage allows the Oldham coupling to compensate for angular misalignment by enabling the hubs to rotate independently about their own axes. The sliding action of the middle block accommodates axial misalignment by allowing the hubs to move slightly closer or farther apart.

The use of sliding contact instead of direct physical contact between the hubs minimizes friction, backlash, and wear, making the Oldham coupling an efficient and reliable method for transmitting torque while accommodating misalignment.

Overall, the Oldham coupling’s ability to handle both angular and axial misalignment ensures smooth and precise torque transmission between shafts, reducing stress on connected equipment and extending the lifespan of mechanical components.

Specific Safety Considerations for Using Oldham Couplings in High-Speed Applications

When using Oldham couplings in high-speed applications, there are several safety considerations to keep in mind to ensure the safe and efficient operation of the machinery:

1. Material Selection: Choose high-quality materials for the Oldham coupling components to withstand the stresses and forces experienced at high speeds.

2. Proper Installation: Ensure the coupling is installed correctly and securely to prevent any chances of coupling failure or disengagement during high-speed operation.

3. Balancing: Balance the coupling components accurately to minimize vibration and prevent excessive wear, which can be more pronounced at high speeds.

4. Regular Inspections: Implement a regular inspection and maintenance schedule to identify any signs of wear, misalignment, or damage that may occur due to high-speed operation.

5. Lubrication: Use appropriate lubrication to reduce friction and heat generation, which is crucial in high-speed applications.

6. Temperature Consideration: Monitor the temperature of the coupling during operation as high speeds can result in increased heat generation.

7. Avoid Overloading: Do not exceed the recommended torque and speed limits specified by the manufacturer to avoid overloading the coupling.

8. Coupling Guards: Consider using coupling guards or covers to protect personnel from rotating or moving coupling components in high-speed systems.

9. Emergency Shutdown: Install an emergency shutdown system to quickly stop the machinery in case of coupling failure or other emergencies.

10. Compliance with Standards: Ensure that the Oldham coupling and its installation comply with industry standards and regulations for high-speed applications.

By adhering to these safety considerations and implementing preventive measures, the risk of accidents, machinery damage, and downtime in high-speed applications can be significantly reduced. Always consult the coupling manufacturer’s guidelines and follow best practices for safe operation and maintenance.

Can an Oldham Coupling be Used in Both Horizontal and Vertical Shaft Orientations?

Yes, an Oldham coupling can be used in both horizontal and vertical shaft orientations. The design of the Oldham coupling allows it to accommodate misalignment between shafts in multiple directions, including axial, angular, and parallel misalignments.

In horizontal shaft arrangements, the Oldham coupling can handle misalignment between two parallel shafts while transmitting torque smoothly and efficiently. It is commonly used in various power transmission applications where two shafts are relatively close together and require a reliable coupling to compensate for misalignment.

In vertical shaft orientations, the Oldham coupling can handle axial misalignment, which is the misalignment between the rotational axes of the two shafts. This makes it suitable for applications where the connected shafts are not perfectly aligned due to gravitational forces or other factors.

The Oldham coupling’s ability to accommodate misalignment in both horizontal and vertical shaft orientations makes it a versatile choice for a wide range of mechanical systems, including pumps, compressors, conveyor systems, and more. However, it is essential to ensure proper installation and maintenance to maximize the coupling’s performance and service life in any shaft orientation.

How an Oldham Coupling Accommodates Misalignment Between Shafts

An Oldham coupling accommodates misalignment between shafts through its unique design, which consists of three main components:

  1. Two Hubs: Each hub is attached to the shaft of the connected equipment. The hubs have a series of slots around their circumference.
  2. Middle Block: The middle block fits between the two hubs and has perpendicular slots on its inner diameter. It connects the two hubs while allowing relative movement between them.

When the shafts experience angular or axial misalignment, the middle block slides within the slots of both hubs. The perpendicular slots on the middle block engage with the slots on the hubs, creating a parallelogram linkage.

This parallelogram linkage allows the Oldham coupling to compensate for angular misalignment by enabling the hubs to rotate independently about their own axes. The sliding action of the middle block accommodates axial misalignment by allowing the hubs to move slightly closer or farther apart.

The use of sliding contact instead of direct physical contact between the hubs minimizes friction, backlash, and wear, making the Oldham coupling an efficient and reliable method for transmitting torque while accommodating misalignment.

Overall, the Oldham coupling’s ability to handle both angular and axial misalignment ensures smooth and precise torque transmission between shafts, reducing stress on connected equipment and extending the lifespan of mechanical components.

Product Description

Custom CNC Turning Machining  Spline Shaft Couplings Steering Shaft Coupler Oldham Coupling
 

Product Description

 

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. 

Our leading mainly including universal couplings, drum gear couplings, elastic couplings etc.
Main production equipments:
Large lathe, surface grinder, milling machine, spline milling machine, horizontal broaching machine, gear hobbing machine, shaper, slotting machine, bench drilling machine, radial drilling machine, boring machine, band sawing machine, horizontal lathe, end milling machine, crankshaft grinder, CNC milling machine, 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.

It is widely used in metallurgical steel rolling, wind power, hydropower, mining, engineering machinery, petrochemical, lifting, paper making, rubber, rail transit, shipbuilding and marine engineering and other industries.

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.
If you cannot determine the type, you can contact our professional engineer.

Transmission of Torque in Oldham Couplings

An Oldham coupling is designed to transmit torque between two shafts that are misaligned but parallel to each other. It consists of three components: two hubs (also known as drive hubs) and a center disc. The hubs are connected to their respective shafts, while the center disc sits between them.

The center disc of the Oldham coupling is characterized by slots or keyways on its opposite sides, which engage with the hubs. The slots allow the center disc to slide or float within the hubs while maintaining a constant angular velocity between the shafts.

When torque is applied to the drive hub on one side, it induces a rotational force on the center disc. This rotational force is then transferred to the other drive hub, which results in torque transmission to the second shaft. The center disc acts as an intermediary between the two hubs, compensating for any axial or radial misalignment between the shafts.

Regarding the question of different shaft diameters, the Oldham coupling can accommodate shafts with different diameters as long as the hub design allows for a secure connection. The keyways or slots in the center disc and hubs should be compatible with the shaft dimensions to ensure proper torque transmission and to prevent slippage or damage.

It is essential to select the appropriate size and design of the Oldham coupling to match the shaft diameters and to ensure reliable torque transmission while accommodating any misalignment between the shafts.

What are the Potential Limitations or Drawbacks of Using an Oldham Coupling?

While Oldham couplings offer numerous advantages, they also have some limitations and drawbacks that should be considered when selecting a coupling for a specific application:

1. Limited Misalignment Capacity: Oldham couplings can only accommodate small amounts of angular and axial misalignment between the shafts. They are not suitable for applications with high levels of misalignment as excessive misalignment can lead to premature wear and failure of the center disc.

2. Speed Limitations: Oldham couplings are generally not recommended for high-speed applications. The flexible center disc has a maximum speed limit, and exceeding this limit can cause the disc to fatigue and fail over time.

3. Temperature Sensitivity: The performance of Oldham couplings can be affected by temperature fluctuations. Extreme temperatures can impact the flexibility and integrity of the center disc material, leading to reduced coupling performance.

4. Backlash in High-Precision Systems: While Oldham couplings minimize backlash compared to some other couplings, they may still have some inherent clearance between the hubs and the center disc, leading to a slight amount of backlash. In ultra-high-precision systems, this slight backlash may be a concern.

5. Material Compatibility: The material used for the center disc must be chosen carefully to ensure compatibility with the specific application’s environment and the media being conveyed. Some aggressive chemicals or harsh environments may degrade the material over time.

6. Maintenance: Oldham couplings require periodic inspection and maintenance to ensure proper functioning. The center disc may wear out over time and need replacement, especially in applications with high torque or frequent start-stop cycles.

Despite these limitations, Oldham couplings remain a popular choice in many applications due to their vibration reduction, backlash minimization, and moderate misalignment compensation capabilities. However, it is essential to carefully assess the specific requirements of the application and consider the potential drawbacks before selecting an Oldham coupling.

oldham coupling

Can an Oldham Coupling be Used in Precision Motion Control Applications?

Yes, an Oldham coupling can be used in precision motion control applications. Oldham couplings are known for their ability to provide constant velocity transmission while accommodating misalignment. These couplings offer low backlash and minimal hysteresis, making them suitable for precision motion control systems.

Precision motion control applications require accurate and repeatable motion, which can be achieved by using an Oldham coupling. The coupling’s design allows it to handle angular misalignment without introducing significant axial or radial forces. This feature helps maintain the accuracy and integrity of the motion control system.

Oldham couplings are often used in applications such as robotics, CNC machines, optical equipment, and other systems where precise positioning and smooth motion are essential. Their ability to reduce vibration and minimize backlash is particularly beneficial in these applications, as it enhances the system’s overall performance and accuracy.

When selecting an Oldham coupling for precision motion control, it is essential to consider factors such as the required torque capacity, speed, and shaft sizes. Additionally, regular maintenance and proper alignment are crucial to ensure the coupling’s optimal performance in precision applications.

What is an Oldham Coupling and How Does It Function in Mechanical Systems?

An Oldham coupling is a type of flexible coupling used in mechanical systems to transmit torque between two shafts that are misaligned. It consists of three main components: two hubs or discs and a middle block. The two hubs are connected to the respective shafts, and the middle block sits in between them.

The key feature of the Oldham coupling is the middle block, which has slots on its opposite faces and is connected to the hubs using pins or keys. The slots in the middle block are oriented perpendicular to each other, allowing the middle block to move in a plane perpendicular to the axis of the shafts.

When torque is applied to one shaft, it is transmitted to the middle block of the coupling. Due to the slots, the middle block can slide laterally as the shafts rotate, accommodating both angular and axial misalignments between the shafts. This sliding action helps to reduce the reaction forces and wear that would otherwise occur in rigid couplings when misalignment is present.

Oldham couplings are known for their ability to provide constant velocity transmission even when misalignment exists. They do not have any backlash, which means there is minimal play between the coupling components during rotation. This feature makes them suitable for precision applications where accurate torque transmission and positioning are required.

One of the main advantages of the Oldham coupling is that it effectively isolates the connected shafts from each other, which can help in reducing vibrations and noise. Additionally, it can compensate for parallel misalignment between the shafts, making it ideal for applications where parallel shafts need to be connected while allowing some degree of misalignment.

Oldham couplings are commonly used in various industrial machinery and automation systems, including CNC machines, robotics, printing presses, and conveyor systems. They are particularly useful in applications where precise torque transmission, misalignment compensation, and low maintenance are essential.

Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded. Selection, installation and maintenance of couplings can lead to reduced maintenance time and maintenance cost.

What are the Potential Limitations or Drawbacks of Using an Oldham Coupling?

While Oldham couplings offer numerous advantages, they also have some limitations and drawbacks that should be considered when selecting a coupling for a specific application:

1. Limited Misalignment Capacity: Oldham couplings can only accommodate small amounts of angular and axial misalignment between the shafts. They are not suitable for applications with high levels of misalignment as excessive misalignment can lead to premature wear and failure of the center disc.

2. Speed Limitations: Oldham couplings are generally not recommended for high-speed applications. The flexible center disc has a maximum speed limit, and exceeding this limit can cause the disc to fatigue and fail over time.

3. Temperature Sensitivity: The performance of Oldham couplings can be affected by temperature fluctuations. Extreme temperatures can impact the flexibility and integrity of the center disc material, leading to reduced coupling performance.

4. Backlash in High-Precision Systems: While Oldham couplings minimize backlash compared to some other couplings, they may still have some inherent clearance between the hubs and the center disc, leading to a slight amount of backlash. In ultra-high-precision systems, this slight backlash may be a concern.

5. Material Compatibility: The material used for the center disc must be chosen carefully to ensure compatibility with the specific application’s environment and the media being conveyed. Some aggressive chemicals or harsh environments may degrade the material over time.

6. Maintenance: Oldham couplings require periodic inspection and maintenance to ensure proper functioning. The center disc may wear out over time and need replacement, especially in applications with high torque or frequent start-stop cycles.

Despite these limitations, Oldham couplings remain a popular choice in many applications due to their vibration reduction, backlash minimization, and moderate misalignment compensation capabilities. However, it is essential to carefully assess the specific requirements of the application and consider the potential drawbacks before selecting an Oldham coupling.

How do Temperature and Environmental Conditions Affect the Performance of an Oldham Coupling?

The performance of an Oldham coupling can be influenced by temperature and environmental conditions. The choice of materials used in the coupling’s construction plays a vital role in determining its suitability for specific operating environments. Here are some factors to consider:

Temperature: Extreme temperatures can affect the material properties of the Oldham coupling components. High temperatures can lead to thermal expansion, which might cause changes in the coupling’s dimensions and interfere with its performance. In contrast, low temperatures can make materials more brittle, reducing the coupling’s ability to withstand torque and misalignment. It is essential to select materials that can operate effectively within the temperature range of the intended application.

Corrosive Environments: In corrosive environments, such as chemical processing plants or marine applications, it is crucial to use materials that are resistant to corrosion. Stainless steel and other corrosion-resistant alloys are commonly used in such conditions to ensure the longevity and reliability of the Oldham coupling.

Dust and Contaminants: Dust, dirt, and other contaminants can accumulate on the coupling’s moving parts, leading to increased wear and reduced performance. Regular cleaning and maintenance are essential in environments where dust and contaminants are prevalent.

Humidity and Moisture: High humidity or moisture can lead to the formation of rust or corrosion on metal components. For applications in such environments, it is essential to use materials with proper corrosion resistance or consider protective coatings.

Shock and Vibration: In applications where the coupling is subjected to high levels of shock and vibration, it is essential to ensure that the coupling’s design and materials can withstand these dynamic forces without premature failure.

Proper selection of materials and regular maintenance can help mitigate the impact of temperature and environmental conditions on the performance of an Oldham coupling. Additionally, consulting with coupling manufacturers or engineering experts can provide valuable insights into choosing the most suitable coupling for specific operating conditions.

Materials Used in Manufacturing Oldham Couplings

Oldham couplings are commonly made from various materials to suit different application requirements. The choice of material depends on factors such as torque capacity, operating conditions, and environmental considerations. Some of the commonly used materials in manufacturing Oldham couplings include:

  • Aluminum: Aluminum is a popular choice for Oldham couplings due to its lightweight and excellent machinability. It is suitable for low to medium torque applications and offers good corrosion resistance.
  • Stainless Steel: Stainless steel is known for its high strength, corrosion resistance, and durability. Oldham couplings made from stainless steel are ideal for applications requiring higher torque transmission and operating in harsh or corrosive environments.
  • Acetal: Acetal, also known as Delrin, is a thermoplastic material with good mechanical properties. It provides low friction and wear resistance, making it suitable for applications where reduced friction is essential.
  • Nylon: Nylon is another thermoplastic material used in Oldham couplings. It offers good chemical resistance and is often chosen for applications with moderate torque requirements.
  • Carbon Steel: Carbon steel is robust and cost-effective, making it suitable for heavy-duty applications. It has high strength and can handle higher torque loads compared to some other materials.
  • Brass: Brass is a durable metal that offers good corrosion resistance. Oldham couplings made from brass are suitable for certain industrial and marine applications.

The material selection for an Oldham coupling depends on factors such as the torque to be transmitted, operating speed, environmental conditions, and budget constraints. Manufacturers often offer a range of material options to meet the diverse needs of different industries and applications.

Programming With Couplings

A coupling is a mechanical device that connects two shafts together and transmits power. Its purpose is to join rotating equipment and allows some degree of end-movement or misalignment. There are many different types of couplings. It’s important to choose the right one for your application.

Mechanical connection between two shafts

There are many ways to achieve mechanical connection between two shafts, including the use of a coupling. One common type is the beam coupling, which is also known as a helical coupling. It is used for transmission of torque between two shafts. This type of connection accommodates axial, parallel and angular misalignments.
The hubs and shafts of a worm gear are connected together by a coupling. This mechanical connection allows one shaft to turn another without causing a mechanical failure. This type of coupling is made from sliding or rubbing parts to transfer torque. However, the coupling is not designed to withstand jerks, so it isn’t suitable for high-speed applications.
The use of a coupling is common in machinery and equipment. It helps transmit power from one drive shaft to the other, while adding mechanical flexibility. It is also useful for reducing the impact and vibration caused by misalignment. It also protects the drive shaft components from wear and tear.
A double-hook coupling can be used to provide a uniform angular velocity at the driven shaft. Another example is a double-jointed coupling. A double-jointed coupling can be used to connect shafts that are not directly intersecting. The double-jointed yoke can be used for the same purpose.
A shaft coupling is a device that maintains a strong mechanical connection between two shafts. It transfers motion from one shaft to another, at all loads and misalignments. Unlike a conventional linkage, a shaft coupling isn’t designed to allow relative motion between the two shafts. Couplings often serve several purposes in a machine, but their primary use is torque and power transmission.

Functions that control the flow of another function

One of the simplest programming constructs is a function that controls the flow of another function. A function can take an argument and return a different value, but it must be ready to return before it can pass that value to another function. To do this, you can use the goto statement and the if statement. Another way to control flow is to use a conditional statement.

Criteria for selecting a coupling

There are several important factors to consider when choosing the right coupling. One of the most important factors is coupling stiffness, which depends on the material used and the shape. The stiffness of a coupling determines its ability to resist elastic deformation. A stiff coupling is desirable for certain types of applications, but it’s undesirable for others. Stiffness can reduce the performance of a system if there’s too much inertia. To avoid this, ensure that the coupling you choose is within the recommended limits.
The size of a coupling is also important. Different coupling types can accommodate different shaft sizes and shapes. Some couplings have special features, such as braking and shear pin protection. When choosing a coupling, you should also consider the type of driven equipment. If you need to connect a high-torque motor, for example, you’ll want to choose a gear coupling. Likewise, a high-speed machine may require a disc coupling.
Another factor to consider when selecting a coupling is the torque rating. Despite its importance, it’s often underestimated. The torque rating is defined as the torque of the coupling divided by its OD. In some cases, torque may fluctuate during a cycle, requiring a coupling with a higher torque rating.
Torsionally flexible couplings are also important to consider. Their design should be able to withstand the torque required during operation, as well as the required speed. The coupling should also have a high degree of torsional stiffness, as well as damping. Furthermore, a damping coupling can reduce the energy wasted through vibration.
The sizing of a coupling is also determined by the torque. Many engineers use torque to select the correct coupling size, but they also take into consideration torsional flexibility and torsional stiffness. For example, a shaft may be able to handle large torque without damaging the coupling, while a disk may be unable to handle large amounts of torque.
Besides torque, another important consideration in coupling selection is the cost. While a coupling may be cheaper, it may be less reliable or easier to maintain. Couplings that are difficult to service may not last as long. They may also require frequent maintenance. If that’s the case, consider purchasing a coupling with a low service factor.
There are many different types of couplings. Some require additional lubrication throughout their lifetime, while others are 100% lubrication-free. An example of a 100% lubrication-free coupling is the RBI flexible coupling from CZPT. This type of coupling can significantly reduce your total cost of ownership.
In addition to the above-mentioned benefits, elastomeric couplings are low-cost and need little maintenance. While they are often cheaper than metallic couplings, they also have excellent shock absorption and vibration dampening properties. However, they are susceptible to high temperatures. Also, they are difficult to balance as an assembly, and have limited overload torque capacity.
