TRANSMISSION WITH DOUBLE-SUN, ANNULAR GEAR, AND OUTER GEAR COPLANAR GEAR SET

摘要

A transmission includes a coplanar gear set with a first sun gear member rotatable about a first axis of rotation, a second sun gear member rotatable about the first axis of rotation, a carrier member, and an outer gear radially outward of and concentric with the first sun gear member. A first annular gear meshes with the first sun gear member, and the outer gear meshes with the first annular gear and with the second sun gear member. The first annular gear is rotatable about a second axis of rotation and the outer gear is rotatable about a third axis or rotation.
