The working principle of plum coupling

　　The working principle of the plum coupling is to install a plum-shaped elastic ring (damping pad) of rubber (polyurethane) material between the claws of the two half couplings of the same shape (the claws and the damping pad are matched ) To complete the connection of the two halves of the coupling.The plum blossom coupling transmits power through the kneading between the claws and the elastic ring. The elastic deformation of the elastic ring compensates for the relative deviation of the two shafts to achieve the effect of damping and buffering.

　　Raw material analysis of plum blossom coupling: plum blossom coupling is also called claw coupling or plum blossom elastic coupling. We all know that it is composed of two metal claw discs and an elastic body.What are the commonly used plum coupling main materials? In fact, the main materials of the coupling main body are: 45 steel, 40CrMo, stainless steel, cast steel, cast iron, aluminum alloy, etc. The actual use is mostly 45 steel , ML type plum blossom coupling is widely used in the model.However, aluminum alloys are also useful when load sensitivity is required.

　　The elastic element of the plum coupling is similar to the plum shape, also known as the plum elastic cushion (commonly known as the cushion). There are mainly 3 kinds of raw materials, rubber, polyurethane, and nylon.Polyurethane materials are used more frequently. When replacing elastic elements, we need to move the two halves of the metal claws axially (except for LMD and LMS models).Plum petals mainly have four petals, six petals, eight petals, ten petals, and twelve petals. MT1: four petals, MT2-MT7 six petals, MT8-MT9: eight petals, MT10-MT12: ten petals, MT13-MT14: twelve petals.
