The plum coupling is named for its elastomer plum shape. According to the elastomer material, it can be divided into: rubber-shaped plum coupling, polyurethane plum coupling; polyurethane elastomer is usually used, which can be divided according to its performance and use. For, plum-shaped elastic couplings, plum-shaped couplings for servo motors, clamping-type plum-shaped couplings, etc., are available in keyway type, clamping type, extended type, flange type and many other types;
The characteristics of plum-shaped elastic coupling are:
1. Compact, no backlash, providing three different hardness elastomers;
2. It can absorb vibration and compensate radial and angular deviation;
3. Simple structure, convenient maintenance and easy inspection;
4. Maintenance-free, oil-resistant and electrical insulation, working temperature 20 degrees -60 degrees;
5. Plum blossom elastomer has four petals, six petals, eight petals and ten petals;
6. The fixing methods include top wire, clamping and keyway fixing.
