What is a coupling

       Couplings belong to the category of general mechanical parts. They are used to connect two shafts (active shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In the high-speed and heavy-duty power transmission, some joints The shaft device also has the function of buffering, damping and improving the dynamic performance of the shafting. The shaft 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. It is the most commonly used coupling component for shaft transmission of mechanical products. In the late 20th century, coupling products at home and abroad have developed rapidly. How to choose from a variety of couplings with different performances in product design can meet the requirements of the machine For most designers, the coupling is always a troublesome problem. Commonly used couplings include diaphragm couplings, drum gear couplings, universal couplings, * couplings, and elastic couplings. Shaft and serpentine spring coupling.
