CRV-C series

The first stage of CRV C series reducer is planetary gear reduction. The rotation of the sun gear is transmitted from the large gear on the sun 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.

The eccentric shaft rotates once, and the cycloid will rotate one tooth in the opposite direction to the movement of the eccentric shaft.

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
