The bearing lubricating system comprises a casing having a bore which defines a reservoir and a well sized to receive a sufficient volume of a suitable liquid lubricant. A return passage in the casing allows fluid flow from the well to the reservoir. A shaft extends through the reservoir and through the well. At least one bearing is situated in the bore between the reservoir and the well. A pumper element is mounted on the shaft for rotation therewith within the well. A pair of end seals seal off the opposite ends of the bore from the ambient.

Compact self-lubricating bearing system

The novel controlled-flow lubricating system utilizes a casing that forms, in use, an enclosed oil well. At least one bearing is disposed inside the well. A shaft is journaled in the bearing. A pumping member is pressed onto the shaft adjacent to the bearing for rotation therewith. Upon rotation with the shaft, the pumping member forcefully injects lubricant from one side to the opposite side of the bearing, thereby flushing, cleaning and lubricating the bearing's engaging surfaces. The preferred pumping member is a circular impeller having a plurality of vanes facing an eccentric cavity in an opposite portion of the wall in the well. This eccentric cavity and the impeller intensify the flow of the recirculating lubricant between the well and the reservoir.
