· Polyurethane elastomer is Iimited by a convex claw block, which can avoid the internal deformation caused by the impact and the external deformation produced by centrifugal force
· The large surface of convex claw, which can reduce the pressure on the surface of the involute tooth
· Can compensate the relative deviation, buffer, shock absorption, abrasion resistance of the two axles
· Be suitable for the connect ion of transmission shaft for two coaxial lines, which is widely used
