What is the function of coupling and clutch

       Coupling and clutch are used to connect shaft and shaft (or other moving parts) to transmit motion and torque. They can also be used as a * device for overload protection. The difference is that the coupling cannot be separated during machine operation. , It can be disconnected only after the machine is stopped; the clutch can be engaged or disconnected at any time during the operation of the machine, and the coupling can compensate for the offset of the connecting parts due to the alignment. When the angle is used to transmit motion or torque, when selecting, you should first determine the selected coupling or clutch type, and then select the model in the phase standard according to the calculated torque to be transmitted.
