Can an Oldham Coupling Reduce Vibration and Backlash in Mechanical Systems?
Yes, an Oldham coupling can help reduce vibration and minimize backlash in mechanical systems, making it a popular choice for applications that require precise and smooth power transmission.
Vibration Reduction: Oldham couplings are designed with a three-piece construction, comprising two hubs and a center disc. The center disc, also known as the spacer, is made of a flexible material such as acetal or nylon. When torque is transmitted through the coupling, the center disc flexes, absorbing any misalignment between the shafts. This flexing action helps dampen vibration and reduces resonance in the system, leading to smoother operation and less mechanical stress on connected components.
Backlash Minimization: Backlash is the amount of play or free movement between the mating parts of a mechanical system. In traditional couplings like gear couplings, there can be significant backlash due to the nature of the gear teeth. However, Oldham couplings have a unique design that allows them to transmit torque with minimal backlash. The center disc provides a small amount of clearance between the hubs, enabling smooth rotation without backlash. This characteristic is especially beneficial in applications that require precise motion control, such as robotics and CNC machines.
Overall, the flexible and backlash-free nature of Oldham couplings makes them well-suited for applications where vibration reduction and precise motion control are essential. By reducing vibration and backlash, Oldham couplings contribute to the overall efficiency, accuracy, and reliability of the mechanical system they are employed in.
Real-World Examples of Oldham Coupling Usage in Mechanical Engineering
Oldham couplings are widely used in various mechanical engineering applications due to their ability to transmit torque while compensating for angular misalignment. Here are some real-world examples of Oldham coupling usage:
- Packaging Machinery: Oldham couplings are commonly employed in packaging machines that require precise and continuous motion. These couplings help connect the motor shaft to various components in the packaging process, such as conveyor belts, rollers, and cutting blades.
- Automated Assembly Lines: In automated assembly lines, Oldham couplings are utilized to transfer torque from the motor to the robotic arms or handling mechanisms. The couplings enable smooth and accurate movement, ensuring precise positioning of components during assembly.
- Printing Equipment: Printing machines utilize Oldham couplings to transmit power from the motors to the printing cylinders and rollers. The couplings accommodate any misalignment between the shafts and minimize vibration, resulting in improved print quality.
- Material Handling Systems: Material handling systems, such as conveyor systems, use Oldham couplings to connect drive motors to the conveyor belts. These couplings facilitate the efficient transfer of goods while compensating for any misalignment that may occur during operation.
- Industrial Pumps: Oldham couplings are employed in industrial pumps to transfer power from the motor to the pump impeller. They aid in absorbing vibration and maintaining alignment, which is crucial for the pump’s optimal performance and longevity.
- Medical Devices: Some medical devices, such as scanning equipment and diagnostic machines, incorporate Oldham couplings to ensure precise and reliable motion, contributing to accurate medical imaging and diagnosis.
These examples demonstrate the versatility of Oldham couplings in various mechanical engineering applications. Their ability to handle misalignment, reduce vibration, and transmit torque makes them a valuable component in many industrial sectors.
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:
- Two Hubs: Each hub is attached to the shaft of the connected equipment. The hubs have a series of slots around their circumference.
- 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.

How to Calculate the Required Size and Specifications for an Oldham Coupling
Calculating the required size and specifications for an Oldham coupling involves considering several key factors. Here’s a step-by-step guide to help you with the calculations:
- Identify the Torque Requirements: Determine the maximum torque that the coupling needs to transmit between the two shafts. This can be done by analyzing the torque demands of the application and considering safety factors.
- Select the Coupling Material: Based on the operating conditions and the type of machinery, choose a suitable material for the Oldham coupling. Common materials include aluminum, stainless steel, and acetal.
- Calculate the Bore Diameter: Measure the diameters of the shafts that the coupling will connect. The bore diameter of the coupling should match the shaft diameters for a proper fit.
- Determine the Coupling Size: The coupling’s size is typically specified by its outside diameter and length. Ensure that the selected coupling size fits within the available space in the mechanical system.
- Consider Misalignment Compensation: Oldham couplings can accommodate angular misalignment. However, it’s essential to check the coupling’s rated misalignment capability to ensure it meets the application’s requirements.
- Check Operating Speed: Verify that the selected coupling can handle the rotational speed (RPM) of the application without exceeding its critical speed.
- Factor in Environmental Conditions: If the coupling will be exposed to harsh environmental conditions or corrosive substances, choose a material that can withstand these conditions.
Once you have gathered all the necessary information and made the calculations, you can select the appropriate Oldham coupling that meets the requirements of your specific application. It’s important to consult with coupling manufacturers or engineering experts to ensure the coupling’s compatibility and reliability in your system.
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 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.

Typical case of diaphragm coupling applied to variable frequency speed control equipment
JMB type coupling is applied to HangZhou Oilfield Thermal Power Plant
According to the requirements of HangZhou Electric Power Corporation, HangZhou Oilfield Thermal Power Plant should dynamically adjust the power generation according to the load of the power grid and market demand, and carry out the transformation of the frequency converter and the suction fan. The motor was originally a 1600KW, 730RPM non-frequency variable speed motor matched by HangZhou Motor Factory. The speed control mode after changing the frequency is manual control. Press the button speed to increase 10RPM or drop 10RPM. The coupling is still the original elastic decoupling coupling, and the elastic de-coupling coupling after frequency conversion is frequently damaged, which directly affects the normal power generation.
It is found through analysis that in the process of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the speed regulation process (the diameter of the fan impeller is 3.3 meters) and is cut off, which has great damage to the motor and the fan.
Later, they switched to the JMB460 double-diaphragm wheel-type coupling of our factory (patent number: ZL.99246247.9). After 1 hour of destructive experiment and more than 1 year of operation test, the equipment is running very well, and there is no Replace the diaphragm. 12 units have been rebuilt and the operation is in good condition.

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:
- Two Hubs: Each hub is attached to the shaft of the connected equipment. The hubs have a series of slots around their circumference.
- 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.

Can an Oldham Coupling Reduce Vibration and Backlash in Mechanical Systems?
Yes, an Oldham coupling can help reduce vibration and minimize backlash in mechanical systems, making it a popular choice for applications that require precise and smooth power transmission.
Vibration Reduction: Oldham couplings are designed with a three-piece construction, comprising two hubs and a center disc. The center disc, also known as the spacer, is made of a flexible material such as acetal or nylon. When torque is transmitted through the coupling, the center disc flexes, absorbing any misalignment between the shafts. This flexing action helps dampen vibration and reduces resonance in the system, leading to smoother operation and less mechanical stress on connected components.
Backlash Minimization: Backlash is the amount of play or free movement between the mating parts of a mechanical system. In traditional couplings like gear couplings, there can be significant backlash due to the nature of the gear teeth. However, Oldham couplings have a unique design that allows them to transmit torque with minimal backlash. The center disc provides a small amount of clearance between the hubs, enabling smooth rotation without backlash. This characteristic is especially beneficial in applications that require precise motion control, such as robotics and CNC machines.
Overall, the flexible and backlash-free nature of Oldham couplings makes them well-suited for applications where vibration reduction and precise motion control are essential. By reducing vibration and backlash, Oldham couplings contribute to the overall efficiency, accuracy, and reliability of the mechanical system they are employed in.

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.

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.
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.

Typical case of diaphragm coupling applied to variable frequency speed control equipment
JMB type coupling is applied to HangZhou Oilfield Thermal Power Plant
According to the requirements of HangZhou Electric Power Corporation, HangZhou Oilfield Thermal Power Plant should dynamically adjust the power generation according to the load of the power grid and market demand, and carry out the transformation of the frequency converter and the suction fan. The motor was originally a 1600KW, 730RPM non-frequency variable speed motor matched by HangZhou Motor Factory. The speed control mode after changing the frequency is manual control. Press the button speed to increase 10RPM or drop 10RPM. The coupling is still the original elastic decoupling coupling, and the elastic de-coupling coupling after frequency conversion is frequently damaged, which directly affects the normal power generation.
It is found through analysis that in the process of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the speed regulation process (the diameter of the fan impeller is 3.3 meters) and is cut off, which has great damage to the motor and the fan.
Later, they switched to the JMB460 double-diaphragm wheel-type coupling of our factory (patent number: ZL.99246247.9). After 1 hour of destructive experiment and more than 1 year of operation test, the equipment is running very well, and there is no Replace the diaphragm. 12 units have been rebuilt and the operation is in good condition.

Can an Oldham Coupling Reduce Vibration and Backlash in Mechanical Systems?
Yes, an Oldham coupling can help reduce vibration and minimize backlash in mechanical systems, making it a popular choice for applications that require precise and smooth power transmission.
Vibration Reduction: Oldham couplings are designed with a three-piece construction, comprising two hubs and a center disc. The center disc, also known as the spacer, is made of a flexible material such as acetal or nylon. When torque is transmitted through the coupling, the center disc flexes, absorbing any misalignment between the shafts. This flexing action helps dampen vibration and reduces resonance in the system, leading to smoother operation and less mechanical stress on connected components.
Backlash Minimization: Backlash is the amount of play or free movement between the mating parts of a mechanical system. In traditional couplings like gear couplings, there can be significant backlash due to the nature of the gear teeth. However, Oldham couplings have a unique design that allows them to transmit torque with minimal backlash. The center disc provides a small amount of clearance between the hubs, enabling smooth rotation without backlash. This characteristic is especially beneficial in applications that require precise motion control, such as robotics and CNC machines.
Overall, the flexible and backlash-free nature of Oldham couplings makes them well-suited for applications where vibration reduction and precise motion control are essential. By reducing vibration and backlash, Oldham couplings contribute to the overall efficiency, accuracy, and reliability of the mechanical system they are employed in.
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.
