1.Compact size and small inertia.

2.The coupling uses engineering plastics as elastic , with cushioning ,vibration reductionand wear resistence ,the working temperature is -35-+80.

3.The elastomer is limited byconvex claw block ,which can avoid internal deformation caused by impact and external deformationcaused by centrifugal force. the large concave surface of the convex claw makes the surface pressure on the involute tooth very small, even if the tooth bears overload, the tooth will not wear or deform.
