초록

An output shaft air/oil separator system comprises an outer housing, an oil passage, a spline shaft having a cavity formed therein that communicates with the oil passage, an output shaft disposed at least partially within the spline shaft cavity that has a first section spaced apart from an inner surface of the spline shaft to form a gap therebetween in communication with the spline shaft cavity and a second section contacting at least a portion of the spline shaft inner surface, a housing cavity defined by at least a portion of an outer surface of the s...
