The plum coupling is processed by machining methods such as turning, milling, and broaching, and then undergoes overall heat treatment.In order to ensure sufficient mechanical strength, there is also a claw plate on the market that is a casting, which can be produced in large quantities and eliminates processing losses.So the price is much lower than machining. But the performance of castings is not very good.Don't use it in some important occasions.And the claws of the casting are prone to tooth punching (claws falling off) at high speed or high load.

(1)Compact, no backlash, providing three different hardness elastomers;

(2) Vibration can be absorbed, and radial and angular deviation can be compensated;

(3) Simple structure, convenient maintenance and inspection;

(4) Maintenance-free, oil-resistant and electrical insulation, working temperature 20℃-60℃;

(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.
