ABSTRACT:
A speed reducing transmission includes roller driving elements operating to transmit torque between opposed trochoidally formed surfaces. The device may have one or multiple reduction stages and may be either counterbalanced or counterweighted to achieve dynamic balance. The opposed surfaces are provided as conjugate epitrochoidal and hypotrochoidal gear elements, while the rollers are simple cylinders maintained suitably spaced by means of roller cages or retainers.
