Abstract

An outer rotor(2) has a star-shaped bore(3) with fine internal teeth(4). An inner rotor(5) is eccentrically mounted in the bore and has pockets(6) holding planetary gear wheels(7) with fine teeth(8) which roll around the fine teeth of the outer rotor. Planetary gears have one tooth less than the internal teeth of the outer rotor. An independent claim is made for a process for manufacturing the gear wheel arrangement in which the component parts are formed either by powder metallurgy, injection molding, flow molding, punching or pressure die casting, especially in aluminum.
