ABSTRACT:
A planocentric gear drive has an eccentrically floating driving gear for simultaneously engaging a stator gear and a rotatable output gear to rotate the output gear through relatively small angular increments. The stator and output gears have different numbers of teeth and are mounted coaxially for engaging the driving gear on a common axial line of contact wherein the stator and output gear teeth are in local axial alignment at the line of contact. The driving gear is attracted into meshing engagement with the stator and output gears by a circumferentially arranged plurality of electromagnets energizable in sequence to rotate the driving gear eccentrically in steps about the stator and output gears. During this eccentric rotation, the common axial line of contact revolves in steps about the stator and output gears, with the output gear rotating through small angular increments to permit the stator and output gear teeth to remain in axial alignment at the revolving line of contact. When energization of the electromagnets ceases, the driving gear engaging the stator and output gears locks the output gear against rotation with respect to the stator gear.
