Characteristic of Non-stretching and Shortening Universal Coupling
The two axes connected by SWP-D universal coupling without extension and shortening will change the relative position of the two axes due to manufacturing and installation errors, deformation after loading and the influence of temperature change, etc., which often can not guarantee strict alignment. Coupling can be divided into rigid coupling, flexible coupling and coupling according to whether the coupling has elastic elements and compensating capacity for various relative displacements, i.e. whether it can maintain the connection function under the condition of relative displacement and the use of the coupling. The main types, characteristics and functions of coupling in transmission system. Note that rigid coupling can only transmit motion and torque, and has no other functions, such as flange coupling, sleeve coupling, clamp coupling and flexible coupling without elastic elements. It can not only transmit motion and torque. In addition, the flexible coupling with elastic elements, such as tooth coupling, universal coupling, chain coupling, slider coupling, diaphragm coupling, can transmit motion and torque, and the axial, radial and angular compensation performance has different degrees. To improve the working performance of the transmission system, the vibration reduction and cushioning functions include various flexible coupling with non-metallic elastic elements and flexible coupling with metal elastic elements. The structures of various flexible coupling are different and different, and their functions in the transmission system are also different. The coupling transmits motion and torque, and protects against overload. Flexible coupling also has different compensation performance, including pin type, friction type, magnetic powder type, centrifugal type, hydraulic type and so on.
