Lubrication system for right-angle drives used with utility vehicles

Abstract

A bearing lubrication device in a right angle gear reducer includes a gear housing having an interior portion and a lubricating fluid reservoir therein. An oil slinger, rotating pinion shaft, pinion shaft housing, and bearings for supporting the pinion shaft within the pinion shaft housing work together to provide a continuous supply of oil to the bearings. The pinion shaft includes two radially and longitudinally extending passageways therethrough which supply oil from a recess in one end of the pinion shaft to the bearings. Oil is slung from the reservoir into the recess of the rotating pinion shaft where it is forced outwardly and through the passageways to a chamber formed by the rotating pinion shaft, shaft housing and bearings. The roller bearings pump the oil from the chamber back to the fluid reservoir. Oil passageways in the shaft housing enable the return of oil from one bearing set.
