The plum blossom elastic coupling is composed of two half couplings with the same shape of the protruding claw and the elastic element. The plum blossom elastic element is placed between the protruding claws of the two coupling halves to realize the coupling of the two coupling halves. Join. It has the characteristics of compensating the relative offset of the two shafts, vibration reduction, buffering, small radial size, simple structure, no need for lubrication bearing, high load capacity, and easy maintenance. The basic type plum blossom-shaped elastic coupling needs to move the two coupling halves in the axial direction when replacing the elastic element. The double flange type can replace the elastic element without moving the axial coupling half. Suitable for connecting two coaxial lines, frequent starting, changeable forward and reverse rotation, medium and low speed, medium and small power transmission shafting, and working parts that require high work reliability. The basic plum blossom elastic coupling is not suitable for heavy loads and shafts. Dimensionally restricted, difficult to center the two axes after replacing the elastic element. The materials of plum blossom-shaped elastic elements include polyurethane and cast nylon. Choose different materials according to different working conditions, such as fans, water pumps, light industry, textiles, etc. work smoothly, when the load does not change much, you can choose polyurethane. The prices of the two materials differ greatly. The transmission torque is 20～2500N·m, and the working environment temperature is -35～80℃.
