ABSTRACT:
An infinitely variable rotary drive transmission system which provides a true infinitely variable speed range that begins with zero output and accelerates smoothly and steplessly into the over-drive range, provides limitless horsepower capacity and does not require a clutch mechanism to change speeds. The infinitely variable rotary drive transmission system comprises an input shaft, hub assembly, a plurality of identical differential gear assemblies and a plurality of cam rod assemblies operatively coupled to vary the rotational output velocity of an output shaft.
