The tooth end of the outer gear sleeve of the star coupling is in the shape of a horn, so it is not suitable for high speed and impact load, nor for the connection of vertical shafts. Star couplings are sometimes mistaken for plum couplings, because their appearance after installation is almost similar, but under the same model, the star coupling bears a large torsion force. Compared with the plum coupling, its inner hole and The shape can be made small.
When the star coupling is running at high speed, the radial movement due to the centrifugal force will accelerate its wear. The polyurethane elastomer is limited by the convex claw block, which can avoid the internal deformation caused by the impact and the external deformation caused by the centrifugal force. ; The large concave surface of the claws makes the surface pressure on the involute teeth very small, and even if the teeth are overloaded, the teeth will not be worn or deformed. Axial plug-in assembly, convenient for blind installation, saving time; small size, small moment of inertia, maintenance-free; easy for visual inspection.
The star-shaped elastic coupling is composed of two half-couplings with the same shape of the claws and elastic elements. The star-shaped elastic elements are placed between the claws of the two half-couplings to realize the join.
The structure of the coupling is basically the same as that of the plum blossom elastic coupling. The difference lies in the shape of the elastic elements, which are star-shaped and plum blossom-shaped respectively. The performance is the same as that of the plum blossom elastic coupling. Vibration, cushioning performance, small radial size, simple structure, no need for lubrication, high bearing capacity, easy maintenance and so on. It is suitable for connecting two coaxial lines, frequent starting, changeable forward and reverse rotation, and transmission torque.
