Abstract

The present disclosure provides a lubricating system for a dual splined hollow shaft. A fluid dam is formed circumferentially within the hollow shaft to control the lubrication of the dual splines. The fluid dam includes a pair of sidewalls extending radially inward from the inner wall of the hollow shaft to a height defined by a top wall. A channel formed through the pair of sidewalls permits the movement of lubricant between splines of the hollow shaft. An egress port extends from the top wall of the dam through the outer wall of the hollow shaft to permit lubricant to exit the hollow shaft.
