ABSTRACT:
A differential comprises a pair of face gears, a carrier rotatably mounted between the face gears and a plurality of pinion gears rotatably mounted on the carrier and intermeshing with the face gears for differentially permitting one face gear to rotate relative to the other face gear. The pinion gears are each rotatably mounted in bearings and a lubrication system is provided for pumping lubricating fluid to the bearings for lubrication and cooling purposes. The lubrication system comprises a double-acting pump mounted adjacent to the carrier and a rocker arm pivotally mounted adjacent to each end of the pump. A first end of the rocker arm engages a cam attached to the carrier whereas a second thereof engages an end of a piston rod reciprocably mounted in the pump to pump lubricating fluid to the bearing.
