CRV-E Series

The first stage of CRV E reducer is planetary gear reduction. The rotation of the input shaft is transmitted from the input gear to the planetary gear, and the speed is reduced according to the gear ratio.

The second stage is the deceleration of the cycloid pinwheel. The planetary gear is connected with the eccentric shaft. The rotation of the eccentric shaft drives the cycloid to make an eccentric movement. The eccentric shaft rotates once, and the cycloid will rotate one tooth in the opposite direction to the movement of the eccentric shaft.

Working Principle

Input shaft speed ratio:

R=1+Z₂/Z₁*Z₃

R: Speed ratio

Z₁ : Number of teeth on input gear

Z₂: Number of teeth on planetary/epicyclic gear

Z₃: Number of pins
