Abnormal noise in the diaphragm of the diaphragm coupling

The gap between the bolt fitting section of the diaphragm coupling and the flange hole fitting section is generally based on the bolt diameter of 0.20mm ~ 0.30mm. This fitting section plays a key role in transmitting torque. If the gap exceeds the standard, replace it.The diameter gap between the inner hole of the buffer sleeve and the diaphragm rivet and the bolt is 0.5mm～0.7mm, which plays the role of pressing and positioning the diaphragm.If the bolt is installed in the direction of the bolt, it is easy to cause the bolt to deviate, and the diaphragm will be twisted and deformed.Therefore, pay attention to the direction of the bolt when installing the bolt. Do not install the bolt direction at will, otherwise the diaphragm will be twisted, and long-term operation will damage the surface of the diaphragm and the bolt mating section and the small holes of the half shaft joint.

The performance of abnormal noise in the diaphragm of the diaphragm coupling:

1. There is a problem with the motor speed plate, and the speed becomes faster and slower, causing the diaphragm coupling to ring.

2. The speed difference between the passive end and the active end causes vibration and abnormal noise.

3. The gap between the diaphragm coupling is wide, so that the diaphragm is subjected to greater shaft power, causing abnormal noise due to bolt wear.

4. Excessive shaft deviation of the diaphragm coupling will also cause vibration and abnormal noise in the equipment.

The diaphragm coupling is composed of several groups of diaphragm bolts (select different types of bolts according to different outer diameters) and the two halves of the coupling tightly. Each group of diaphragms is made up of several pieces, and the diaphragm is divided into circles. Different shapes such as type or triangle type.

1. Install it correctly.Install in strict accordance with the factory instructions, and check the coaxiality during installation.

2. Regularly check the use condition to see if the diaphragm is damaged and the nut is loose.

3. Replace the damaged diaphragm in time.

To install the diaphragm coupling, the important thing is to install the bolts. The correct installation of it will directly affect the performance, life and performance of the diaphragm coupling, otherwise it will cause waste of manpower and accessories.Therefore, the correct installation of the bolt direction is a key part, and you must remember not to install it backwards or drop any small parts including spring washers, so that the bolt assembly can exert its excellent performance and will not damage other parts of the coupling.

Insert the bolt from the outside of the small hole in the flange, and then pass it into the diaphragm hole (pay attention to the direction of the diaphragm, the diaphragm is composed of many single sheets, rivets and rivet washers, the rivet washers should be in contact with the buffer sleeve, otherwise It will affect the service life of the rivet set), and then insert the buffer sleeve, elastic washer, and tighten the nut from the outside of the large hole of the flange, so that the bolt does not rotate, because the bolt and the flange match section The surface is a very important part of the torque transmission, and the integrity of the surface directly affects the performance.
