Abstract: A circular wave drive system is provided. In one aspect, the drive comprises: a compliant input ring gear, wherein input ring gear includes internal input ring gear teeth; an input cycloidal disc having an outer surface, wherein the input cycloidal disc includes external input cycloidal disc gear teeth, and wherein the external gear teeth engage the internal gear teeth; a compliant primary drive gear having an outer surface, wherein the primary drive gear includes external primary drive gear teeth; an eccentric motion generator having an eccentric portion and a non-eccentric portion and wherein a centerline of the eccentric portion and the non-eccentric portion are offset, and wherein the eccentric motion generator includes a hollow central bore; and an output cycloidal disc, wherein the output cycloidal disc includes internal output cycloidal disc teeth, and wherein the internal output cycloidal disc teeth engage the external primary drive gear teeth.

Abstract: A circular wave drive system is provided. In one aspect, the circular wave drive includes a compliant input ring gear having an inner surface having internal input ring gear teeth; an input cycloidal disc having an outer surface having external input cycloidal disc gear teeth oriented on the outer surface, and wherein the external input cycloidal disc gear teeth at least partially engage the internal input ring gear teeth; a compliant primary drive gear having an outer surface having external primary drive gear teeth; an eccentric motion generator including an eccentric portion and a non-eccentric portion and wherein a centerline of the eccentric portion and the non-eccentric portion are offset from one another; and an output cycloidal disc having an inner surface with internal output cycloidal disc teeth, and wherein the internal output cycloidal disc teeth at least partially engage the external primary drive gear teeth.
