Planetary cycloid reducerMechanical efficiency is the percentage of output power and input power, we certainly hope that the higher the mechanical efficiency the better, but after a long time will also reduce the mechanical efficiency, we can improve the mechanical efficiency through which.
Theoretically speaking, if the planetary cycloid reducer is a rigid body, there is no efficiency loss in its transmission, but in practice, the material used to manufacture the planetary cycloid reducer cannot be a rigid body, and there is inevitable elastic deformation, which consumes energy when repeated elastic deformation occurs; the material used to manufacture the planetary cycloid reducer cannot be a rigid body.
Moreover, the elastic deformation makes the planetary cycloid reducer engagement no longer a theoretical pure rolling, there will be sliding friction.
Furthermore the actual manufacturing accuracy is unlikely to reach the theoretical accuracy, which also makes the actual engagement different from the theory and no longer pure rolling.
There is also the factor of theoretical smoothness and flatness of the actual planetary cycloid reducer tooth surface non-rigid body, which also affects the actual planetary cycloid reducer meshing.
So all of these reasons are causes that can cause the mechanical efficiency of the planetary cycloid reducer to decrease.
