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.

Чи можна використовувати муфту Oldham у системах точного керування рухом?
Так, муфту Oldham можна використовувати в системах точного керування рухом. Муфти Oldham відомі своєю здатністю забезпечувати передачу постійної швидкості, одночасно компенсуючи перекіс. Ці муфти мають низький люфт і мінімальний гістерезис, що робить їх придатними для систем точного керування рухом.
Для прецизійного керування рухом потрібні точні та повторювані рухи, чого можна досягти за допомогою муфти Oldham. Конструкція муфти дозволяє їй обробляти кутові зміщення без створення значних осьових або радіальних сил. Ця функція допомагає підтримувати точність і цілісність системи керування рухом.
Муфти Oldham часто використовуються в таких сферах застосування, як робототехніка, верстати з ЧПК, оптичне обладнання та інші системи, де важливі точне позиціонування та плавний рух. Їхня здатність зменшувати вібрацію та мінімізувати люфт є особливо корисною в цих сферах застосування, оскільки це підвищує загальну продуктивність та точність системи.
Вибираючи муфту Oldham для точного керування рухом, важливо враховувати такі фактори, як необхідний крутний момент, швидкість та розміри вала. Крім того, регулярне технічне обслуговування та правильне вирівнювання мають вирішальне значення для забезпечення оптимальної роботи муфти в точних застосуваннях.
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.
