Abstract
A planetary gearbox includes a housing having a pair of stops, a planet bearing mounted in the housing, and a planet gear rotatable on the planet bearing. The planet bearing is formed from an axially aligned planet pin and a thrust washer. The thrust washer includes two integrally-formed projections, each facing one of the stops to prevent rotation of the thrust washer about the planetary axis. The thrust washer also includes first thrust surfaces disposed on a first side of the thrust washer facing the housing, first lubrication channels formed axially opposite the first thrust surfaces and extending radially outwards, second thrust surfaces circumferentially offset from the first thrust surfaces and disposed on a second side of the thrust washer facing the planet gear, and second lubrication channels formed axially opposite the second thrust surfaces and extending radially outwards.
