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.

Typical Applications of Oldham Couplings
Oldham couplings find various applications in different industries due to their unique features and benefits. Some typical applications include:
1. Industrial Machinery: Oldham couplings are commonly used in industrial machinery, such as conveyor systems, packaging machines, and assembly lines. They help transmit torque between shafts while accommodating misalignment, reducing vibration, and protecting sensitive components.
2. Robotics and Automation: Oldham couplings are employed in robotics and automation systems to connect motor shafts and other mechanical components. Their ability to handle misalignment and their compact design make them suitable for precision movements and robotic applications.
3. Printing and Labeling: In printing and labeling machines, Oldham couplings are utilized to connect rollers and drive shafts. They ensure accurate and reliable torque transmission while allowing for angular misalignment that may occur during operation.
4. Medical Equipment: Oldham couplings are used in medical equipment, such as imaging devices and surgical instruments. Their low backlash and smooth operation are crucial for precise positioning and reducing wear on sensitive medical components.
5. Automotive Industry: In automotive applications, Oldham couplings are used in various systems, including windshield wipers, power seat adjustments, and steering mechanisms. They aid in transferring torque smoothly and maintaining alignment even in dynamic conditions.
6. Textile Machinery: Textile manufacturing equipment often incorporates Oldham couplings to connect spindles and other rotating components. These couplings allow for misalignment while delivering reliable power transmission in high-speed textile processes.
7. Food and Beverage Processing: Oldham couplings are suitable for food and beverage processing machinery, where hygiene and precision are critical. They help connect drive shafts in mixers, conveyors, and packaging equipment.
8. Aerospace and Defense: In aerospace and defense applications, Oldham couplings are used in systems that require reliable torque transmission while compensating for misalignment and vibration. They can be found in various aircraft and defense equipment.
These are just a few examples of the many applications where Oldham couplings play a vital role in ensuring smooth and efficient power transmission and minimizing the wear and tear of mechanical systems.
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.
Advantages of Using an Oldham Coupling Compared to Other Types of Couplings
An Oldham coupling offers several advantages over other types of couplings, making it a preferred choice in certain applications:
- Misalignment Compensation: The Oldham coupling can handle both angular and axial misalignments between shafts. It allows for up to a few degrees of misalignment while transmitting torque smoothly, reducing the risk of premature wear and failure caused by misalignment.
- No Backlash: Unlike some other flexible couplings, the Oldham coupling has minimal backlash. This means there is little to no play or clearance between the coupling components during rotation, ensuring precise torque transmission and positioning in high-precision applications.
- Vibration and Noise Damping: The sliding action of the middle block in the coupling helps to isolate the shafts from each other, reducing vibrations and noise during operation. This feature is beneficial in applications where vibration dampening is critical to equipment performance and longevity.
- High Torque Transmission: Oldham couplings can handle relatively high torque transmission, making them suitable for applications with moderate to high torque requirements.
- Low Maintenance: Due to its design, the Oldham coupling experiences minimal wear during operation, leading to lower maintenance requirements and longer service life.
- Easy Installation: Oldham couplings are relatively easy to install and remove, simplifying maintenance and replacement procedures.
- Electrically Insulating: Some Oldham couplings are available with non-conductive materials, providing electrical isolation between shafts, which is essential in certain applications.
- Cost-Effective: Compared to other high-performance couplings, Oldham couplings are often more cost-effective, providing reliable performance without breaking the budget.
Overall, the Oldham coupling is an excellent choice in applications where misalignment compensation, precision torque transmission, vibration dampening, and low maintenance are critical factors for successful operation. Its unique design and features make it suitable for various industrial and automation systems, contributing to smoother and more efficient mechanical power transmission.
