The diaphragm coupling is exquisite and can be easily damaged if it is misused during use or not installed correctly.Therefore, the deviation is within the tolerance range of the normal operation of the coupling.Diaphragm couplings have a wide range of applications, but the quality of diaphragm couplings is the key to affecting the transmission torque, use cost and service life of the coupling, and the diaphragm couplings on the market seem to be separated Quite a few, strict implementation of standards to manufacture precision diaphragm couplings makes the cost performance of the coupling (comparison of performance and price) highly praised by actual users. Below we will introduce how the diaphragm coupling is precisely manufactured:

　　Diaphragm coupling mother body manufacturing.The choice of the matrix material of the diaphragm coupling is very important. Generally, the 45# or 40CR forging material should be selected and the rough machining should be carried out after the normalizing treatment. After the rough machining, the quenching and tempering treatment should be carried out to form the overall machine of the coupling material. The performance reaches its performance state. After quenching and tempering, the finishing process is performed, and the mechanical dynamic balance test is required after finishing. The important diaphragm coupling must be nitridated to ensure the transmission strength of the coupling matrix.
