ABSTRACT:
A drive mechanism (10) is used, for example, in an orbiting radial motor (12) to rotate a sprocket (22) or in a multiple output speed increaser or reducer to control output. The drive mechanism (10) has a first member (16) positioned about and rotatable relative to a frame (14). A second member (18) is positioned generally between the frame (14) and first member (16) and engages and rotates the first member (16). The first member (16), for example, is connected to and rotates the sprocket (22) for driving a track of a work vehicle. The drive mechanism (10) has only a single element (34) for establishing the drive ratio of the first member (16) relative to the second member (18) and receiving and transmitting reaction torquing force on the second member (18) in response to the second member (18) engaging the first member (16). Thus, reaction loads on, for example, bearings (68,70) supporting the second member (18) are substantially eliminated and the drive ratio can be widely varied.
