ABSTRACT:
To provide a harmonic drive gearing with high degree of freedom in terms of layout. A harmonic drive gearing10includes a circular spline1′, having outer teeth formed on an outer peripheral surface; an flexible spline2, positioned at the outside of the circular spline1′, and having inner teeth, which are engageable with the outer teeth of the circular spline1′, formed on an inner peripheral surface; and a rotor16which is disposed at outside of the flexible spline2and serves as a wave generator, wherein the rotor16deflects the flexible spline2by minor axis portions of the inner peripheral surface of the flexible spline2and engages the inner teeth of the flex spline with the outer teeth of the circular spline1′ and thereby the engagement position between the inner teeth and the outer teeth is adapted to move in a circumferential direction.
