ABSTRACT:
A sealing assembly for regulating the flow of lubricant to a rotating shaft and to the bearings which support it. The shaft is supported on rolling-contact bearings to which are coupled bearing collars. The bearing collars serve as spray-off edges for removing lubricant from the bearings, which after removal, is received in a groove formed between the bearing and a seal member. This groove is in liquid communication with an opening to the surface of the shaft which, as it rotates, centrifuges lubricant from the groove. The shaft is encircled by the seal member which includes several chambers for receiving lubricant sprayed off the shaft at several spray-off edges. At the end of the seal member furthest from the rolling-contact bearings an outlet for the lubricant of the same size as the inlet is provided, thereby reducing pressure differences between the inlet and the outlet.
