| description | An improved gerotor gear set and an improved method of selecting design parameters therefore are provided. The gerotor gear set (11) includes an inner rotor (17) defining a tip radius (TR), and an outer rotor (13). The axes of the rotors are offset by an eccentricity (E). The profile of the inner rotor is generated by a theoretical internal tooth (15) having a generating radius (GR). The relative orbital and rotational motion of the rotors defines, alternately, a single point clearance (SPC) and a double point clearance (DPC). Iterative adjustments are made in the tip radius (TR) and the generating radius (GR) until both the SPC and DPC are approximately equal to a desired tip clearance (TC). |
