ABSTRACT:
A power transmission system utilizes a pair of pulleys in spaced parallel relation interconnected by a plurality of endless drive belts. Each pulley contains a plurality of eccentric drive lobes. The drive lobes have no teeth or means for increasing sliding friction between the lobes and each drive belt. Drive belts contain no apertures or joints and may be constructed of multiple wraps of any fiber or filament. A plurality of drive lobes spaced equally, about a 360-degree arc, link both shafts fully providing a smooth and even delivery of continuous turning force in either direction of rotation.
