ABSTRACT:
An improved planetary transmission employs orbiting means including a first circular plate having a peripheral array of similar sockets shaped as arcs of circles. A set of similar uncaptured generally cylindrical rollers is rotatively seated in said sockets, said rollers having their curved surfaces projecting beyond the periphery of said plate. A first annular nonorbiting gear having an inner surface formed with a hypo-cycloidal curvature with a number of lobes exceeding by at least one the number of sockets in the plate, encircles the plate so that its inner surface is in rolling contact with rollers and they are free to rotate within their sockets. A second annular nonorbiting gear has surfaces in cooperating encircling engagement with said orbiting means. A first rotary shaft is keyed to one of said nonorbiting gears, and a second rotary shaft is provided to eccentrically drive said orbiting means.
