Application Case
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.

Different Sizes and Configurations of Oldham Couplings
Yes, Oldham couplings are available in various sizes and configurations to suit different applications and requirements. The sizes and configurations can vary based on factors such as torque capacity, shaft diameter, and overall dimensions. Some common variations include:
1. Shaft Diameters: Oldham couplings come in a range of shaft diameter options to accommodate different motor and shaft sizes. They can be found in standard metric and imperial sizes, making them compatible with various equipment and machinery.
2. Torque Capacity: Oldham couplings are designed to handle different torque capacities. The torque capacity of a coupling depends on its size, materials used, and overall construction. High-performance couplings can transmit higher torques, while smaller couplings may be suitable for lighter applications.
3. Coupling Length: The length of the coupling can vary, and some designs allow for compact installations in confined spaces, while others may have longer lengths for specific applications.
4. Materials: Oldham couplings are manufactured using various materials such as aluminum, stainless steel, and composite materials. The choice of material depends on factors like the operating environment, chemical resistance, and desired performance characteristics.
5. Spacer Type: Oldham couplings may have different spacer designs, including straight-spacer and step-spacer configurations. The choice of spacer type can affect the overall stiffness and misalignment capabilities of the coupling.
6. Hub Style: Oldham couplings come with different hub styles, such as set screw, clamp, or compression-style hubs, to accommodate various shaft attachment methods and ease of installation.
7. Backlash: Couplings may have different backlash characteristics, allowing for minimal angular play between the hubs to reduce vibration and shock loads.
Manufacturers of Oldham couplings typically provide detailed specifications and product catalogs that outline the available sizes and configurations. It’s essential to select the right coupling size and configuration that matches the requirements of the specific application to ensure optimal performance and longevity.
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.
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.
