Product Description

  Fluid Coupling Chain Jaw Flexible Flange Gear Rigid Spacer Motor Shaft Universal Half Reducer Spline Stainless Steel Elastomeric coupling

A fluid coupling is a torque converter used in mechanical power transmission systems to transmit torque from 1 rotating shaft to another. It consists of 2 halves, the impeller, and the runner, which are placed in a housing filled with a hydraulic fluid such as oil or water.

When one-half of the fluid coupling is rotated, it creates a fluid flow within the housing, which in turn causes the other half to rotate. The fluid coupling uses fluid dynamics principles to transmit torque between the 2 halves, with the amount of torque being proportional to the speed difference between the 2 shafts.

One of the key advantages of a fluid coupling is its ability to provide a smooth and gradual torque transfer between the 2 shafts, without any mechanical connection. This can help to reduce wear and tear on the equipment and improve overall system efficiency.

Fluid couplings are commonly used in various industrial applications, including mining, construction, and marine equipment. They are also used in automotive transmissions, where they can help provide a smooth and efficient torque transfer between the engine and the wheels.

Overall, a fluid coupling provides a reliable and efficient way to transmit torque between 2 rotating shafts, without any mechanical connection. With their ability to provide a smooth and gradual torque transfer, they are a popular choice for a wide range of industrial and automotive applications.

Understanding the torque and speed limits for different mechanical coupling types.

The torque and speed limits of mechanical couplings vary depending on their design, materials, and intended applications. Here’s an overview of the torque and speed considerations for different types of mechanical couplings:

1. Rigid Couplings:

Rigid couplings are typically designed for high torque applications. They provide a direct and solid connection between shafts, making them suitable for transmitting substantial torque without introducing significant flexibility. The torque capacity of rigid couplings depends on the material and size, and they are often used in applications with high power requirements.

Rigid couplings can handle high rotational speeds since they lack flexible elements that may cause vibration or resonance at higher speeds. The speed limits are generally determined by the materials’ strength and the coupling’s balanced design.

2. Flexible Couplings:

Flexible couplings are more forgiving when it comes to misalignment and can accommodate some axial, radial, and angular misalignments. The torque capacity of flexible couplings can vary significantly depending on their design and material.

Elastomeric couplings, such as jaw couplings or tire couplings, have lower torque capacities compared to metal couplings like beam couplings or bellows couplings. The speed limits of flexible couplings are generally lower compared to rigid couplings due to the presence of flexible elements, which may introduce vibration and resonance at higher speeds.

3. Gear Couplings:

Gear couplings are robust and suitable for high-torque applications. They can handle higher torque than many other coupling types. The speed limits of gear couplings are also relatively high due to the strength and rigidity of the gear teeth.

4. Disc Couplings:

Disc couplings offer excellent torque capacity due to the positive engagement of the disc packs. They can handle high torque while being compact in size. The speed limits of disc couplings are also relatively high, making them suitable for high-speed applications.

5. Oldham Couplings:

Oldham couplings have moderate torque capacity and are commonly used in applications with moderate power requirements. Their speed limits are generally limited by the strength and design of the materials used.

6. Universal Couplings (Hooke’s Joints):

Universal couplings have moderate torque capacity and are used in applications where angular misalignment is common. The speed limits are determined by the materials and design of the coupling.

It’s important to refer to the manufacturer’s specifications and recommendations to determine the torque and speed limits of a specific mechanical coupling. Properly selecting a coupling that matches the application’s torque and speed requirements is crucial for ensuring reliable and efficient operation in the mechanical system.

Do mechanical couplings require regular maintenance, and if so, how often?

Yes, mechanical couplings do require regular maintenance to ensure their optimal performance and longevity. The frequency of maintenance depends on various factors, including the type of coupling, the application’s operating conditions, and the manufacturer’s recommendations. Here are some general guidelines for the maintenance of mechanical couplings:

1. Visual Inspection:

Perform regular visual inspections of the coupling to check for signs of wear, damage, or misalignment. Inspect for any corrosion, cracks, or wear on the coupling components.

2. Lubrication:

Some mechanical couplings, especially those with moving parts or sliding surfaces, require periodic lubrication. Follow the manufacturer’s recommendations regarding the type and frequency of lubrication.

3. Torque Verification:

Check the tightness of fasteners, such as set screws or bolts, to ensure that the coupling is securely attached to the shafts. Loose fasteners can lead to misalignment and reduced performance.

4. Alignment Check:

Regularly check the alignment of the connected shafts to ensure that the coupling is operating within its design limits. Misalignment can lead to premature wear and reduced coupling efficiency.

5. Replacement of Worn Components:

If any coupling components show signs of wear or damage beyond acceptable limits, replace them promptly to prevent further issues.

6. Operating Condition Analysis:

Monitor the operating conditions of the mechanical system and assess whether any changes have occurred that may affect the coupling’s performance. Environmental conditions, load variations, and other factors can impact the coupling’s wear rate.

7. Manufacturer’s Guidelines:

Always follow the maintenance recommendations provided by the coupling manufacturer. The manufacturer’s guidelines may include specific inspection intervals and maintenance procedures tailored to the coupling type and application.

The maintenance frequency for mechanical couplings can vary from monthly inspections for high-demand applications to annual inspections for less demanding conditions. In some cases, couplings in critical systems may require more frequent inspections to ensure their reliability.

Implementing a proactive maintenance program for mechanical couplings helps identify potential issues early and prevents unexpected failures that can lead to costly downtime and repairs. Regular maintenance extends the life of the coupling, improves system efficiency, and enhances overall operational safety.

How does a mechanical coupling facilitate the connection between two shafts?

A mechanical coupling plays a critical role in connecting two shafts in a mechanical system and enabling the transmission of torque and motion between them. The process of how a mechanical coupling facilitates this connection can be explained as follows:

1. Physical Linkage:

A mechanical coupling physically links the two shafts together. It consists of two mating components that fit over the respective shaft ends, ensuring a secure connection.

2. Torque Transmission:

When the motor or driving shaft rotates, it generates torque. This torque is transmitted through the mechanical coupling to the driven shaft, causing it to rotate as well.

3. Keyways or Spline Connection:

Many mechanical couplings use keyways or splines to enhance the connection between the shafts. Keyways are slots cut into the shaft and coupling, and a key is inserted to prevent relative motion between the two components.

4. Compression or Expansion Fit:

In some couplings, the connection between the shafts is achieved through a compression or expansion fit. The coupling is designed to be slightly smaller or larger than the shaft diameter, creating a tight fit when assembled.

5. Set Screws or Bolts:

Set screws or bolts are often used in mechanical couplings to secure the coupling tightly to the shafts. These screws apply pressure to prevent any relative movement between the coupling and the shafts during operation.

6. Flexible Elements:

Flexible couplings feature elements made of materials like rubber or elastomers that can bend or flex. These elements accommodate misalignment between the shafts while maintaining the connection and transmitting torque.

7. Key Features:

Certain types of couplings, such as gear couplings or disc couplings, utilize teeth or gear features to achieve a strong and precise connection between the shafts. These key features ensure a positive engagement, enhancing torque transmission.

In summary, a mechanical coupling serves as the link between two rotating shafts, enabling them to function together as a single unit. Whether through a tight compression fit, keyways, or flexible elements, the coupling ensures a secure and efficient connection, allowing torque to be transmitted from one shaft to the other, and enabling the mechanical system to perform its intended function reliably.

Explaining the impact of mechanical coupling wear on system efficiency.

Mechanical coupling wear can have a significant impact on the efficiency and performance of a mechanical system. As couplings wear over time, several factors come into play that affect the overall efficiency of the system:

1. Loss of Torque Transmission:

As couplings wear, they may develop gaps or play between the mating components. This can result in a loss of torque transmission between the connected shafts. Reduced torque transmission leads to diminished power transfer and can result in inadequate performance of the system, especially in high-torque applications.

2. Misalignment Issues:

Worn couplings may not effectively compensate for misalignments between the connected shafts. Misalignment can cause additional stress on bearings, gears, and other components, leading to increased wear and reduced system efficiency. It can also result in increased vibration and noise, further impacting the system’s performance.

3. Vibration and Resonance:

Wear in flexible couplings can lead to increased vibration and resonance within the system. Excessive vibrations can cause premature failure of components and reduce the overall system efficiency. Vibrations can also create a safety hazard for operators and equipment.

4. Energy Losses:

Worn couplings may introduce energy losses due to friction and slippage. These losses decrease the overall efficiency of the system and result in additional energy consumption to achieve the desired output.

5. Increased Maintenance Costs:

As couplings wear, they may require more frequent maintenance and replacement. The increased downtime for maintenance and the cost of replacing worn couplings can impact the system’s productivity and increase operational expenses.

6. Reduced System Reliability:

Worn couplings are more prone to sudden failures, leading to unplanned downtime. Unreliable systems can disrupt production schedules, affect product quality, and result in lost revenue.

7. Safety Concerns:

Worn couplings can compromise the safety of personnel and equipment. They may lead to unexpected failures, flying debris, or even catastrophic accidents in severe cases.

8. Impact on Product Quality:

In certain industries, like precision manufacturing or aerospace, system efficiency directly affects product quality. Worn couplings can cause inaccuracies, leading to subpar products and potential rework or rejection.

To maintain optimal system efficiency and prevent these issues, it is crucial to perform regular inspections and maintenance of mechanical couplings. Timely replacement of worn couplings and adherence to manufacturer’s guidelines for installation and maintenance can significantly contribute to the overall efficiency, reliability, and safety of the mechanical system.

What is a spline coupling?

A spline coupling is a type of mechanical coupling used to connect two shafts, allowing torque transmission between them while allowing a small amount of relative movement or misalignment. The term “spline” refers to the ridges or teeth on the coupling’s inner or outer surface, which engage with corresponding ridges or grooves on the shafts.

Spline couplings are commonly used in applications where precise torque transmission, rotational alignment, and axial movement are required. They offer several advantages:

1. Torque Transmission:

By using the interlocking ridges or teeth, spline couplings provide a secure connection between the shafts, ensuring efficient torque transfer from one shaft to the other.

2. Misalignment Compensation:

Spline couplings can accommodate a small amount of angular and parallel misalignment between the connected shafts, allowing flexibility in the mechanical system and reducing stress on bearings and other components.

3. Axial Movement:

Some spline couplings, such as spline shafts, allow limited axial movement, making them suitable for applications where shafts may experience thermal expansion or contraction.

4. High Precision:

Spline couplings provide high precision and repeatability in motion control applications. They are commonly used in robotics, machine tools, and automotive transmissions.

5. Different Types:

There are various types of spline couplings, including involute splines, straight-sided splines, and serrated splines, each with different designs and applications.

It is important to note that spline couplings require precise machining and assembly to ensure proper engagement and torque transmission. They are typically used in applications where high torque, precision, and flexibility are necessary for the system’s performance.

2. Evaluate Shaft Misalignment:

Determine the type and amount of misalignment expected between the connected shafts. If significant misalignment is anticipated, flexible couplings may be more appropriate.

3. Consider Torque and Power Transmission:

Calculate the torque and power that the coupling will need to transmit between the shafts. Ensure that the selected coupling can handle the expected load without exceeding its rated capacity.

4. Assess Operating Speed:

Take into account the operating speed of the system. High-speed applications may require couplings designed for high rotational speeds to avoid issues like resonance.

5. Evaluate Environmental Factors:

Consider the environmental conditions in which the coupling will operate. For example, corrosive or harsh environments may require couplings made from specific materials like stainless steel.

6. Review Space Limitations:

Examine the available space for installing the coupling. In some cases, compact couplings may be necessary to fit within confined spaces.

7. Analyze Misalignment Compensation:

For applications where precise alignment is challenging, choose couplings that offer misalignment compensation, such as flexible couplings or universal couplings (Hooke’s joints).

8. Consider Vibration Damping:

If the application involves vibrations or shock loads, consider couplings with vibration damping properties, like certain types of flexible couplings.

9. Account for Maintenance Requirements:

Factor in the maintenance needs of the coupling. Some couplings may require periodic inspections and replacement of components, while others are relatively maintenance-free.

10. Seek Expert Advice:

If unsure about the most suitable coupling for the application, consult with coupling manufacturers or engineering experts who can provide guidance based on their expertise and experience.

By systematically evaluating these factors and requirements, engineers and designers can narrow down the options and select the most appropriate mechanical coupling that will ensure reliable and efficient operation in the specific application.

Product Description

  Fluid Coupling Chain Jaw Flexible Flange Gear Rigid Spacer Motor Shaft Universal Half Reducer Spline Stainless Steel Elastomeric coupling

A fluid coupling is a torque converter used in mechanical power transmission systems to transmit torque from 1 rotating shaft to another. It consists of 2 halves, the impeller, and the runner, which are placed in a housing filled with a hydraulic fluid such as oil or water.

When one-half of the fluid coupling is rotated, it creates a fluid flow within the housing, which in turn causes the other half to rotate. The fluid coupling uses fluid dynamics principles to transmit torque between the 2 halves, with the amount of torque being proportional to the speed difference between the 2 shafts.

One of the key advantages of a fluid coupling is its ability to provide a smooth and gradual torque transfer between the 2 shafts, without any mechanical connection. This can help to reduce wear and tear on the equipment and improve overall system efficiency.

Fluid couplings are commonly used in various industrial applications, including mining, construction, and marine equipment. They are also used in automotive transmissions, where they can help provide a smooth and efficient torque transfer between the engine and the wheels.

Overall, a fluid coupling provides a reliable and efficient way to transmit torque between 2 rotating shafts, without any mechanical connection. With their ability to provide a smooth and gradual torque transfer, they are a popular choice for a wide range of industrial and automotive applications.

Comparing mechanical couplings with other types of couplings in performance.

Mechanical couplings are an essential component in power transmission systems, and they are often compared with other types of couplings based on their performance characteristics. Let’s explore how mechanical couplings compare with some other common coupling types:

1. Mechanical Couplings vs. Fluid Couplings:

Fluid couplings use hydraulic fluid to transmit torque between the input and output shafts. They offer smooth torque transmission and can act as a torque limiter, protecting the connected equipment from overloads. However, they have some energy losses due to fluid turbulence, which slightly reduces their efficiency compared to mechanical couplings. Mechanical couplings, on the other hand, provide direct and efficient torque transmission without any energy losses due to fluid friction.

2. Mechanical Couplings vs. Magnetic Couplings:

Magnetic couplings use magnetic fields to transfer torque from one shaft to another. They are commonly used in applications where a hermetic seal is required, such as in pumps and mixers. Magnetic couplings have the advantage of being completely leak-proof, unlike mechanical couplings that may require seals in certain applications. However, magnetic couplings have a lower torque capacity compared to many mechanical couplings, and their efficiency can be affected by variations in magnetic field strength and alignment.

3. Mechanical Couplings vs. Hydraulic Couplings:

Hydraulic couplings use hydraulic fluid to transmit torque. They offer high torque capacity and the ability to slip during overloads, acting as a safety feature. However, hydraulic couplings can have energy losses due to fluid friction, making them slightly less efficient than mechanical couplings. Mechanical couplings do not have energy losses related to fluid friction and provide direct torque transmission, making them more efficient in this regard.

4. Mechanical Couplings vs. Electrical Couplings:

Electrical couplings use electromagnetic fields to transfer torque. They are commonly used in high-precision and high-speed applications, such as robotics and aerospace systems. Electrical couplings can have high torque capacity and precise control over torque transmission. However, they require electrical power to function, which may not be suitable for all applications. Mechanical couplings are self-contained and do not require additional power sources, making them more suitable for various types of machinery and equipment.

5. Mechanical Couplings vs. Friction Couplings:

Friction couplings use friction between contacting surfaces to transmit torque. They are simple in design and can slip during overloads, providing protection against excessive loads. However, friction couplings can experience wear and require periodic maintenance. Mechanical couplings, depending on their type, may have a more robust design and may not experience as much wear under normal operating conditions.

In summary, mechanical couplings offer direct and efficient torque transmission without energy losses related to fluid friction or magnetic fields. While other coupling types may have specific advantages in certain applications, mechanical couplings remain a versatile and widely used choice in various industries due to their reliability, simplicity, and ease of maintenance.

What are the key differences between rigid and flexible mechanical couplings?

Rigid and flexible mechanical couplings are two main types of couplings used in various engineering applications. They differ significantly in their design and capabilities, each offering distinct advantages and limitations:

1. Design and Construction:

Rigid Couplings: Rigid couplings are solid and inflexible, typically made from materials like steel or aluminum. They have a compact design and provide a direct, non-flexible connection between the shafts.

Flexible Couplings: Flexible couplings are designed to provide some degree of flexibility between the connected shafts. They often consist of elements made from elastomers, rubber, or flexible materials that can bend or deform.

2. Misalignment Compensation:

Rigid Couplings: Rigid couplings are not designed to accommodate misalignment between the shafts. Precise alignment is critical for their effective operation.

Flexible Couplings: Flexible couplings can compensate for axial, radial, and angular misalignments between the shafts, allowing them to remain connected even when not perfectly aligned.

3. Torque Transmission:

Rigid Couplings: Rigid couplings provide an efficient and direct transfer of torque between the shafts. They are ideal for high-torque applications.

Flexible Couplings: Flexible couplings transmit torque between the shafts while allowing for some torsional flexibility. The torque transmission may not be as efficient as in rigid couplings, but they are suitable for applications with moderate torque requirements.

4. Vibration Damping:

Rigid Couplings: Rigid couplings do not have inherent vibration damping properties.

Flexible Couplings: Flexible couplings can dampen vibrations and shocks caused by imbalances or dynamic loads, reducing wear on connected components and enhancing system stability.

5. Applications:

Rigid Couplings: Rigid couplings are commonly used in applications where precise alignment is critical, such as in machine tools, gearboxes, and other systems requiring high precision.

Flexible Couplings: Flexible couplings find applications in various industries, including pumps, compressors, conveyor systems, automotive powertrains, and wherever misalignment compensation or vibration absorption is needed.

6. Maintenance:

Rigid Couplings: Rigid couplings generally require less maintenance due to their solid and simple design.

Flexible Couplings: Flexible couplings may require occasional maintenance, such as checking and replacing the flexible elements to ensure proper functioning.

In summary, the choice between rigid and flexible couplings depends on the specific requirements of the application. Rigid couplings offer excellent torque transmission and precision but require precise alignment. Flexible couplings accommodate misalignment and dampen vibrations, making them suitable for a wider range of applications but may have slightly lower torque transmission efficiency compared to rigid couplings.

What Is a Coupling?

A coupling is a mechanical device that links two shafts together and transmits power. Its purpose is to join rotating equipment while permitting a small amount of misalignment or end movement. Couplings come in a variety of different types and are used in a variety of applications. They can be used in hydraulics, pneumatics, and many other industries.

Types

Coupling is a term used to describe a relationship between different modules. When a module depends on another, it can have different types of coupling. Common coupling occurs when modules share certain overall constraints. When this type of coupling occurs, any changes to the common constraint will also affect the other modules. Common coupling has its advantages and disadvantages. It is difficult to maintain and provides less control over the modules than other types of coupling.
There are many types of coupling, including meshing tooth couplings, pin and bush couplings, and spline couplings. It is important to choose the right coupling type for your specific application to get maximum uptime and long-term reliability. Listed below are the differences between these coupling types.
Rigid couplings have no flexibility, and require good alignment of the shafts and support bearings. They are often used in applications where high torque is required, such as in push-pull machines. These couplings are also useful in applications where the shafts are firmly attached to one another.
Another type of coupling is the split muff coupling. This type is made of cast iron and has two threaded holes. The coupling halves are attached with bolts or studs.

Applications

The coupling function is an incredibly versatile mathematical tool that can be used in many different scientific domains. These applications range from physics and mathematics to biology, chemistry, cardio-respiratory physiology, climate science, and electrical engineering. The coupling function can also help to predict the transition from one state to another, as well as describing the functional contributions of subsystems in the system. In some cases, it can even be used to reveal the mechanisms that underlie the functionality of interactions.
The coupling selection process begins with considering the intended use of the coupling. The application parameters must be determined, as well as the operating conditions. For example, if the coupling is required to be used for power transmission, the design engineer should consider how easily the coupling can be installed and serviced. This step is vital because improper installation can result in a more severe misalignment than is specified. Additionally, the coupling must be inspected regularly to ensure that the design parameters remain consistent and that no detrimental factors develop.
Choosing the right coupling for your application is an important process, but it need not be difficult. To find the right coupling, you must consider the type of machine and environment, as well as the torque, rpm, and inertia of the system. By answering these questions, you will be able to select the best coupling for your specific application.

Problems

A coupling is a device that connects two rotating shafts to transfer torque and rotary motion. To achieve optimal performance, a coupling must be designed for the application requirements it serves. These requirements include service, environmental, and use parameters. Otherwise, it can prematurely fail, causing inconvenience and financial loss.
In order to prevent premature failure, couplings should be properly installed and maintained. A good practice is to refer to the specifications provided by the manufacturer. Moreover, it is important to perform periodic tests to evaluate the effectiveness of the coupling. The testing of couplings should be performed by qualified personnel.

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.
