Abstract
Provided is a strain wave gearing apparatus which is able to make the most of the structural advantages of the flat form while achieving ideal mesh-engagement without involving a high degree of dimensional precision or any special adjustment mechanism. A strain wave gearing apparatus is provided with a stationary internal gear, a rotary internal gear disposed side by side with the stationary internal gear, a flexible planetary gear disposed on the inner peripheral side thereof for meshing partially with the internal gears by being deflected in the radial direction, and a wave generator disposed inside the flexible planetary gear for continuously deforming and deflecting the flexible planetary gear by rotation. In the apparatus, backlash during mesh-engagement is eliminated by making the base portions and of the internal gears and elastic.
