ABSTRACT:
Gears with a flat drive part provided with a circular guide groove eccentric to the axis of rotation. A flat driven part provided with an endless guide groove centered on the axis of rotation on a face toward the drive part, for guidance of balls transmitting force arranged in radial guide slots in a flange fixed to an outer casing between the driven and drive part. The radial guides hole cover the eccentric deflection of the drive part ball guide groove whereby the balls are secured against rotation around the axis of rotation of the gear. In multiple gears, driven disks corresponding to the number of speeds are provided. A hollow shaft protrudes through the driven disks and contains ball pans to receive balls that may be moved into the associated driven part. A cam slide with cam beads is guided in the hollow shaft. Axial displacement of the cam slide always establishes a rotationally fixed connection between a driven disk and the hollow shaft.
