The wear resistance of the coupling tire body and the reason for the abnormal noise of the diaphragm coupling

　　The coupling tire body is made of rubber and pressed sheet die-casting. The rubber is composed of cloth and steel rims. The wear resistance of the coupling tire body mainly depends on the number of cloth and steel rims.Another important factor is the quality of the glue. These two points are the decisive factors affecting the service life of the coupling.The domestic standard coupling carcass adopts> 2 grade glue, while some manufacturers use secondary black solid glue, which is made by melting the solid to match the steel ring and cloth; the second standard is clear Explain that the tire body with an outer diameter> 150 has 3-5 steel rims and a 2-layer thick cloth dissolved on the tire body. Some manufacturers only use 2 steel rims to dissolve the tire body, which will greatly reduce the tire body. The degree of wear resistance affects the service life of the coupling.

　　Reasons for abnormal noise of diaphragm 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.
