The two shafts connected by the SWP-D type non-telescopic short universal coupling will cause changes in the relative position of the two shafts due to manufacturing and installation errors, deformation after load, and the influence of temperature changes, which often cannot be strictly guaranteed. Centering. According to whether the universal coupling has elastic elements, whether it has the ability to compensate various relative displacements, that is, whether it can maintain the connection function and the purpose of the coupling under the condition of relative displacement, the coupling can be divided into Rigid coupling, flexible coupling and diaphragm coupling.
