The star-shaped elastic coupling is composed of two half-couplings with the same shape of the protruding claws and the elastic element. The star-shaped elastic element is placed between the protruding claws of the two coupling halves to realize the coupling of the two coupling halves. Join. The structure of the coupling is basically the same as the plum blossom-shaped elastic coupling, the difference is that the shape of the elastic element is star-shaped and plum blossom-shaped, the performance is the same as the plum blossom-shaped elastic coupling, and it has certain compensation. Vibration and cushioning performance, small radial size, simple structure, no lubrication bearing, high load capacity, easy maintenance and so on. It is suitable for connecting two coaxial lines, frequent starting, positive and negative change of the transmission shaft system, transmitting torque 20～25000N·m, working environment temperature -35～80℃.
