The two shafts connected by the coupling are affected by many factors such as manufacturing error, installation error, deformation caused by shaft load, base deformation, bearing wear, temperature change (thermal expansion, cold contraction), relative movement between components, etc. Produce relative displacement.Under normal circumstances, the relative displacement of the two shafts is unavoidable, but the displacement direction generated by the shafting transmission under different working conditions, namely axial (x), radial (y), angular (a) and displacement The size varies.Only the flexible coupling has the performance of compensating the relative displacement of the two shafts. Therefore, a large number of flexible couplings are selected in practical applications.Rigid couplings do not have compensation performance and their application range is limited, so the amount used is small.
