Abstract
PURPOSE: To improve the meshing state of gears and prevent the early damage of tooth surfaces and generation of abnormal noise, by providing an annular groove at each of nonmeshing parts of a stationary internal gear and a rotary internal gear on the outer peripheral surface in the direction of the axis of each of a plurality of planetary gears.
CONSTITUTION: At the central part in the direction of the axis of each of three planetary gears 9 and on the outer peripheral surface not meshed with a stationary internal gear 20 and a rotary internal gear 21, there is formed an annular groove 9d. When a sun gear 2, the three planetary gears 9, the stationary internal gear 20 and rotary internal gear 21 are meshed with each other and rotate, the three planetary gears 9 deformes at the position of the annular groove 9d due to the difference in the torsional moments of the stationary internal gear 20 and the rotary internal gear 21, and absorbs the difference of the torsional moments. Thus, the meshing state of three planetary gears 9 and the stationary internal gear 20 and the rotary internal gear 21 is improved.
