ABSTRACT:
A planetary gear assembly includes a sun gear, a ring gear, and more than one planet gear. The sun gear provides rotational input to the gear assembly and intermeshes with the planet gears. The planet gears intermesh with and drive the ring gear. Each of the planet gears have a central bore for receiving a planet pin. The planet pins are supported by the carrier. The planetary gear assembly also includes at least one thrust washer having a plurality of wear surfaces for engaging thrust surfaces on each of the planet gears. The wear surfaces are integrally interconnected by rigid connecting portions to form a single piece washer capable of supporting a thrust load from all of the planet gears. The rigid connecting portions also prevent the thrust washer from rotating with respect to the planet gears.
