The main function of the coupling is that the coupling is a key component that connects two shafts or a shaft and a rotating part. Its main function is to transmit motion and torque to ensure the normal operation of the machine. The coupling can compensate for the offset between the two shafts due to inaccurate manufacturing and installation or deformation and thermal expansion during operation, including axial, radial, angular offset or combined offset.
