Abstract
A shaft is rotatably journalled in a bearing assembly. The shaft has a sleeve fixed thereon at a location axially adjacent to the bearing assembly, and a ring depends from the sleeve into a supply of liquid lubricant contained in an underlying sump. Rotation of the shaft and sleeve causes the ring to rotate about its own axis, and the rotating ring carries lubricant upwardly from the sump, with the thus carried liquid ultimately being returned to the sump by a combination of centrifugal and gravitational forces. A dam is interposed between the underside of the sleeve and the ring depending therefrom to direct a substantial and continuous flow of the returning lubricant to the bearing assembly.
