The plum coupling is machined by machining methods such as turning, milling, and broaching, and then subjected to integral heat treatment. In order to ensure sufficient mechanical strength, there is also a claw plate on the market which is a casting, which can be mass-produced.

Plum couplings two types

The amount of production, and the processing loss is eliminated. So the price is much lower than the machining. But the performance of the casting is not very good. It is best not to use it in some important situations. Moreover, the claws of the casting are prone to toothing (claws falling off) under high speed or high load.

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

(2) absorb vibration and compensate for radial and angular deviation;

(3) Simple structure, convenient maintenance and easy inspection;

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

(5) plum blossom elastomer has four petals, six petals, eight petals and ten petals;

(6) The fixing method has a top wire, clamping, and the keyway is fixed.
