  • Publication number: 20200256445
    Abstract: A strain wave gearing apparatus includes a rigid internal gear including a plurality of teeth on an inner periphery thereof, a cylindrical flexible external gear including a plurality of teeth on an outer periphery thereof, and a wave generator having an elliptic outer periphery. A contact of the outer periphery of the wave generator with an inner periphery of the external gear causes the external gear to be elliptically distorted and meshed with the internal gear at a part of the teeth of the external gear in a direction of a major axis. A rotation of the wave generator causes a position of the mesh to be moved in a circumferential direction. The elliptic outer periphery of the wave generator includes a major axis in common with a reference ellipse, and is different from the reference ellipse in terms of a shape of at least a part thereof in the circumferential direction.
