ABSTRACT:
A low speed high torque motor-gear reducer assembly is disclosed of the type having a first gerotor (motoring gerotor) including a ring member (41) having (N+1) internal teeth (47) and a star (49) having (N) external teeth. A second gerotor (reduction gerotor) includes a ring (85) having (M+1; wherein M does not equal N) internal teeth (89) and a star (91) having (M) external teeth. The internally-toothed portion of the second gerotor is fixed by means of a flange (81) to an output shaft (25). Pressurized fluid is communicated only to the motoring gerotor whereby the output shaft rotates at a speed reduced from the speed of rotation of the star (49) by a reduction factor R wherein: ##EQU1## In accordance with one embodiment of the invention, a third gerotor (support gerotor) is included having a star (103) identical to the star (49) and being in engagement with an intermediate shaft (97) such that the stars (49) and (103) orbit and rotate in unison. The support gerotor absorbs reaction forces transmitted to the intermediate shaft (97) from the reduction gerotor.
