Abstract

PURPOSE: To perform transmission at the optimal reduction gear ratio in such a way that two stages of deceleration are done by one set of planetary gear, load torque is detected by another set of planetary gear, and deceleration is automatically changed over.
CONSTITUTION: In case where reaction force given to an internal gear 27 used for a torque detector by a planetary gear 31 is smaller than retentive force of a spring, the internal gear 2 is fixed, a change-over lever 14 is pulled in the direction of b by a spring 37, a change-over ring 13 is pushed to a carrier 10. This result brings an internal gear 11 to be incorporated with the carrier 10 into rotation, the rotation of an input gear 6 is transmitted to the carrier 10 as it was (high speed stage). When the reaction force has grown bigger than the retentive force of the spring, the internal gear 27 swivels in the direction of c, a wedge-shaped boss on the internal gear 27 thrusts the change-over lever in the direction of (a), which fixes the internal gear 11. As resulted, the rotation of the input gear 6 is decelerated and transmitted to the carrier 10.
