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.

Thermal Considerations and Limits for Continuous Operations with Servo Couplings
Servo couplings, like many mechanical components, can experience temperature changes during continuous operation. It is essential to consider thermal factors and establish temperature limits to ensure the proper functioning and longevity of the couplings. Here are the key thermal considerations and limits:
- Temperature Ratings:
Manufacturers provide temperature ratings for servo couplings, indicating the range of temperatures in which the couplings can operate safely. It is crucial to stay within these specified temperature limits to prevent potential damage to the coupling or its connected components.
- Heat Dissipation:
Servo couplings may generate heat during operation due to friction and torsional loads. The ability of the coupling to dissipate heat effectively helps prevent excessive temperature rise. Choosing a coupling with suitable materials and design can improve heat dissipation.
- Continuous vs. Intermittent Operation:
Servo couplings may have different thermal limits for continuous operation compared to intermittent or start-stop operations. It is essential to ensure that the coupling’s temperature ratings are suitable for the application’s specific mode of operation.
- Environment:
The operating environment can also impact the thermal performance of the servo coupling. High ambient temperatures, confined spaces, or inadequate ventilation can elevate the temperature around the coupling, potentially pushing it beyond its limits.
- Lubrication:
Proper lubrication of the coupling’s components can help reduce friction and heat generation. Using the right lubricant and ensuring regular maintenance can contribute to the coupling’s optimal thermal performance.
- Thermal Expansion:
Thermal expansion of materials can lead to dimensional changes in the coupling. If not accounted for, this expansion can cause misalignment or interference with other components. Understanding the thermal expansion properties of the coupling materials is crucial for precise system design.
- Overheating Prevention:
To prevent overheating, monitoring the coupling’s temperature during continuous operations is advisable. Implementing temperature sensors or thermal monitoring systems can help detect abnormal temperature increases and trigger appropriate actions, such as reducing operating speeds or shutting down the system temporarily.
- Material Selection:
Choosing materials with appropriate thermal properties is vital for withstanding continuous operations. Some materials are more resistant to high temperatures and thermal cycling, making them suitable for applications with demanding thermal conditions.
By considering these thermal considerations and adhering to the specified temperature limits, users can ensure that servo couplings operate reliably and efficiently during continuous operations, avoiding potential failures and ensuring the longevity of the motion control system.

What is a Servo Coupling, and Its Role in Servo Motor Systems
A servo coupling is a specialized type of coupling used in servo motor systems to connect the servo motor shaft to the driven load. Servo motor systems are widely used in various industries for precise motion control applications, where accuracy, speed, and torque control are crucial. The servo coupling plays a vital role in ensuring the efficient transfer of motion and torque from the servo motor to the driven load while compensating for misalignments between the motor and load shafts.
The main functions and role of a servo coupling in a servo motor system are as follows:
- Motion Transmission: The primary function of a servo coupling is to transmit motion from the shaft of the servo motor to the load. It connects the motor shaft to the driven load, such as a ball screw, gearbox, or another mechanical component, enabling the motor to drive and control the motion of the load precisely.
- Torque Transmission: In addition to motion, the servo coupling also transfers torque from the motor to the load. As the servo motor generates rotational force (torque), the coupling efficiently transmits this torque to the driven load, allowing it to perform its intended motion with the required force.
- Misalignment Compensation: Perfect alignment between the servo motor shaft and the load shaft is challenging to achieve in real-world applications. Any misalignment can cause detrimental effects, including increased wear, reduced performance, and premature failure. The servo coupling acts as a flexible element that can compensate for various types of misalignments, such as angular, parallel, and axial misalignments. This flexibility helps to maintain smooth and efficient power transmission even when the motor and load are not perfectly aligned.
- Damping of Vibrations: Servo motor systems often operate at high speeds and with rapid changes in direction. These dynamic movements can generate vibrations that may adversely affect the performance and lifespan of the system. A well-designed servo coupling can dampen these vibrations, providing a more stable and controlled motion to the load, reducing the risk of damage or inaccuracies.
- Backlash Minimization: Backlash refers to the play or gap between the teeth or components of the coupling when the direction of motion is reversed. Excessive backlash can result in lost motion and reduced precision. High-quality servo couplings are engineered to minimize backlash, ensuring accurate bidirectional motion control in the servo motor system.
Overall, a properly selected and installed servo coupling enhances the performance, efficiency, and reliability of servo motor systems. It protects sensitive components, such as bearings and motors, from excessive loads and vibrations, leading to extended equipment life and improved motion control capabilities.
