ABSTRACT:
This invention relates to a self-priming screw pump lubrication system. The system 10 includes a central feed tube which communicates at one end with lubricant in a reservoir or sump and at the other end to the central region of an assembly that includes a horizontally disposed rotating shaft. The shaft having thereon threaded portions of opposite pitch mounted within a pair of mating sleeves which sleeves are biased away from each other at the central region of the assembly. The other ends of the sleeves are in abutting relationship with the outer races of a pair of angular contact bearings to be lubricated. Each of the inner races of the bearings are mounted on the rotary shaft. Lubricant slingers are mounted on the rotating shaft at a point remote from the bearings and cooperate with the lubricant that has been drawn upward through the central feed tube and delivered to and past the bearings, whereupon the slingers propel the lubricant back to the reservoir for reuse.
