Install correctly
Diaphragm couplingBolt method:
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 made up of many single sheets with 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, and the bolt direction must be paid attention to when installing the bolt. , Do not install the bolt direction randomly, otherwise it will cause the diaphragm to twist, and long-term operation will damage the surface of the diaphragm and the bolt mating section, and the small hole of the semi-shaft joint.Because the surface of the mating section between the bolt and the flange is a very important mating section for torque transmission, the integrity of the surface directly affects the performance.
