ABSTRACT:
A harmonic drive in which the teeth on either or both of the flexspline and internal spline have a modified involute profile with a small contact angle when fully meshed, and considerable tip relief. The former preferably comprises three discs in line on an input shaft which is cranked to a small eccentricity, the center disc eccentricity being diametrically opposite that of the outside pair. Pressure lubricated plain bearings are advantageously used.
