Abstract
A compound harmonic drive assembly includes a ring gear assembly, a wave generator, a flex spline, and a rolling element. The wave generator is received within the ring gear assembly along the rotational axis. The wave generator has a body that extends radially between an exterior surface and an interior surface. The body defines at least one groove that extends radially from the exterior surface towards the interior surface. The flex spline is disposed between the ring gear assembly and the wave generator. The rolling element is disposed between the wave generator and the flex spline.
