The radial movement of the star-shaped elastic coupling due to the centrifugal force will accelerate its wear during high-speed operation, and a casing is added.In addition to preventing dust and oil storage, insufficient thinning may cause interference, and excessive thinning will weaken the strength of the tooth, and the backlash will be large.The contact conditions of the external teeth are improved, which avoids the disadvantages of edge extrusion and stress concentration of the straight teeth under angular displacement conditions. At the same time, the friction and wear conditions of the tooth surface are improved, noise is reduced, and the maintenance cycle is long.
The tooth end of the outer gear sleeve of the star-shaped elastic coupling is in the shape of a horn, so it is not suitable for use under high speed and impact load conditions, nor for the connection of vertical shafts.
The shape of the star coupling is almost similar to that of the plum blossom coupling. Under the same model, the star coupling bears more torsion. Compared with the plum blossom coupling, its inner hole and shape can be smaller.
