ABSTRACT:
A double eccentric wave generator assembly for a harmonic drive type transmission having a circular spline and a flexible spline coaxially mounted each having matable gear teeth, a deflection means mounted within said flexspline, said deflection means comprising a pair of wave generating discs journalled on eccentric hubs on a sleeve. The discs are non-parallel with one another so as to present an outer periphery which is parallel to the flexspline when it is coned during deflection thereof. A third disc is disposed on the sleeve to provide shape control to the flexspline during rotation thereof.
