CONTROLLING TRANSMISSION

摘要

Herein disclosed is a controlling transmission to be used with an industrial robot or the like, which is constructed of a planetary or star gear mechanism having at least one pair of intermediate gears arranged between a sun gear and an internal gear. The paired intermediate gears are set by the movement adjustment of a movement adjusting mechanism such that one of them has its back-lash eliminated with respect to the rotations in the clockwise direction whereas the other has its back-lash eliminated with respect to the rotations in the counter-clockwise direction.
