The role of coupling

CouplingIt belongs to the category of general mechanical parts and is used to connect two shafts (driving shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque.In high-speed and heavy-load power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting.The coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft.The general power machine is mostly connected with the working machine by means of a coupling, which is a commonly used connection part for the shaft transmission of mechanical products. In the late 20th century, domestic and international coupling products developed rapidly. In product design, how to choose a coupling that can meet the requirements of the machine from a variety of couplings with different performances? For most designers, It is always a troublesome problem.Commonly used couplings are diaphragm coupling drum gear coupling, universal coupling, * coupling, elastic coupling and serpentine spring coupling.The following figure briefly describes the transmission system diagram between the driving machine and the driven machine, and clarifies the required coupling types.
