Plum coupling elastomers are generally composed of engineering plastics or rubber.The life of the coupling is also an elastic life.Since elasticity is under pressure, it is obviously under tension.The life of the general elastic body is 10 years. Because the elasticity has the function of buffering and damping, it is used more in the occasion of strong vibration.

　　There are two main types of plum blossom couplings, one is a curved (concave) claw type zero-backlash coupling, and the other is a traditional straight claw type.The plum blossom elastic spacer has multiple leaf branches. Like a slider coupling, it also squeezes the plum blossom elastic spacer and the sleeves on both sides to ensure its zero clearance performance.Different from the slider coupling, the plum blossom coupling is driven by squeezing while the slider coupling is driven by shear.

　　5 characteristics of plum coupling:

　　1. The plum blossom coupling has large axial, radial and angular compensation capabilities.

　　2. The work is stable and reliable, with good vibration damping, buffering and electrical insulation properties.

　　3. High-strength polyurethane elastic elements are wear-resistant and oil-resistant, have large carrying capacity, long service life, and reliability.

　　4. The plum blossom coupling does not need lubrication, the maintenance workload is small, and it can run continuously for a long time.

　　5. The plum blossom coupling has simple structure, small radial dimension, light weight and small moment of inertia, suitable for medium and high speed occasions.
