Diaphragm couplingRelying on the elastic deformation of the diaphragm to compensate the relative displacement of the connected two shafts, it is a high-performance flexible coupling with metal elastic elements. It does not need lubrication, has no rotation gap, and is not affected by temperature and oil pollution. It has a compact structure and strength. High, long service life, with the characteristics of alkali resistance, acid resistance and corrosion resistance.
The vulnerable part of the diaphragm coupling is the diaphragm assembly, and the service life of the diaphragm assembly determines the service life and working efficiency of the coupling.This is because when there is angular displacement and axial displacement between the power machine and the working machine, additional stress will be generated in the diaphragm group in the diaphragm coupling that connects the power machine and the working machine.When the diaphragm coupling is in high-speed operation or repeated forward and reverse rotation, the diaphragm group is prone to fatigue damage with the action of alternating stress.
