High-speed diaphragm couplings have good adaptability, especially the elastic deformation of metal diaphragms to compensate the axial, angular and radial relative displacement between the axes, improve the working conditions of the unit, and become a high-speed rotating machine. A commonly used form of join. In the high-speed rotating unit, the distortion of the diaphragm causes poor concentricity, which seriously affects the shaft vibration stability of the unit. The stiffness of the diaphragm coupling is poor, the transverse vibration frequency of the coupling is close to the rotor speed, and the manufacturing precision of the coupling is poor. An unbalanced amount can cause abnormal vibration of the rotor.
