Coupling function and role

        The function of the coupling is to connect the two shafts together. The two shafts cannot be separated when the machine is running. The two shafts can only be separated after the machine is stopped and the connection is disconnected. It is generally useful when the shaft and the shaft are connected to transmit power. The belt pulley or gear is connected, but if the two shafts are required to be in a straight line and require constant speed rolling, a coupling must be used to connect.However, due to increased accuracy, thermal expansion of the shaft, or bending of the shaft during operation, the concentricity between the two shafts will change. Therefore, the flexible coupling can be used as a bridge to maintain the power transmission between the two shafts and absorb the two shafts. The radial, angular and axial deviations between the shafts extend the life of the machine and improve the quality of the machine.
       *The big role is to connect two shafts (sometimes also connect shafts and other rotating parts), make the two shafts rotate together to transmit motion and torque, realize the connection and separation between the shaft and the shaft, so as to realize the power transmission and interruption.The coupling also has the ability to compensate for the deviation of the two shafts to eliminate or reduce the additional load caused by the relative deviation of the two shafts, improve the transmission performance and extend the life of the machine.In order to reduce the vibration of the mechanical transmission system and reduce the impact peak load, the coupling should also have a certain cushioning and shock absorption performance.However, due to the fierce market competition, many manufacturers use fake and inferior products as good products in order to make huge profits, causing consumers to suffer losses. Therefore, it is also important to choose high-quality products.
