Coupling is a device used to connect two adjacent shaft ends. In the mechanical structure, couplings are used to achieve a semi-permanent connection between two adjacent rotating shafts. During the normal use of the machine, this connection generally does not need to be disassembled. In this sense, it can be said that the coupling of the coupling is permanent. But in an emergency, or when the worn parts need to be replaced, the coupling can be disassembled and then connected. <br>The rigid coupling can firmly connect the two shafts together, making it impossible to produce relative motion. Rigid couplings can be used in equipment that requires and can achieve precise centering of the axes of the two shafts. If the propeller in the manufacturing plant or the ship needs a particularly long shaft, it can be manufactured in segments, and then the segments can be connected by a rigid coupling.
