In practical applications, the intermediate shaft type is generally used, which is also called a double diaphragm coupling to improve the performance of two-axis offset compensation.
The bolt is one of the important parts of the double diaphragm coupling. Whether it is installed correctly or not will directly affect the performance life and safety of the diaphragm coupling, otherwise it will cause a certain amount of 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.
The correct method of installing bolts for double diaphragm couplings: insert the bolts from the outside of the small hole in the flange, and then pass into the diaphragm hole (note the direction of the diaphragm, the diaphragm is made of many single sheets, rivets and rivet washers, The rivet washer 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 from the outside of the large hole of the part flange, the elastic washer, and the bolts should not be used when tightening the nut. Rotation, because the surface of the mating section between the bolt and the flange is a very important mating section for torque transmission, and the integrity of the surface directly affects the performance.
The gap between the bolt fitting section of the double diaphragm coupling and the flange hole fitting section is generally based on the bolt diameter of 0.20mm to 0.30mm. This fitting section plays a key role in transmitting torque. If the gap exceeds the standard, it must be replaced.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 bolts are installed in the direction, it is easy to cause the bolts to deviate, and the diaphragm will be distorted.Therefore, you must pay attention to the direction of the bolt when installing the bolt. Do not install the bolt direction at will, 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 holes of the semi-shaft joint.
