The reason for the abnormal noise of the diaphragm coupling

Compared with the gear coupling, the diaphragm coupling has no relative sliding, no lubrication, sealing, no noise, basically no maintenance, more convenient manufacturing, and can partially replace the gear coupling.
 

 1. The gap between the two halves of the coupling is too wide, causing the diaphragm to receive a large axial force, and the stranded hole or the stranded bolt is worn out, causing abnormal noise;
　　2. Excessive axial offset or too large deflection angle of the two halves of the coupling will also cause vibration and abnormal noise during equipment operation;
　　3. When the speed of the active end and the passive end are different, it will cause vibration and abnormal noise when the equipment is running;
　　4. The speed code disc of the motor is faulty, causing the speed of the motor to be fast and slow, and the diaphragm coupling makes abnormal noise.
       Compared with the gear coupling, the diaphragm coupling has no relative sliding, no lubrication, sealing, no noise, basically no maintenance, more convenient manufacturing, and can partially replace the gear coupling.Diaphragm couplings have been widely used in developed countries in the world. In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.
