Couplings are divided into rigid couplings and flexible couplings. Rigid couplings are suitable for places where two shafts can be strictly aligned without relative displacement during work.The flexible coupling is suitable for the deflection of the two shafts (can be divided into coaxial lines, parallel axes, intersecting axes) or relative displacement during work (can be divided into axial displacement, radial displacement, angular displacement, and comprehensive displacement )The place.Flexible couplings are divided into non-elastic elements, metal elastic elements and non-metallic elastic elements. The latter two are collectively referred to as elastic couplings. According to different stiffness properties, elastic couplings have fixed stiffness elastic couplings and Variable stiffness elastic coupling.
