The function of the coupling is to connect two shafts (active shaft and driven shaft) in different mechanisms to rotate together and transmit torque. Some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting. .
The coupling consists of two halves, which are respectively coupled to the drive shaft and the driven shaft. Most of the general power machines are connected to the working machine by means of a coupling, which is the most commonly used connecting component for the shafting transmission of mechanical products. Commonly used couplings are diaphragm coupling, tooth coupling, plum coupling, slider coupling, drum gear coupling, universal coupling, safety coupling, flexible coupling And serpentine spring couplings.
