ABSTRACT:
Apparatus to lubricate generator bearings with an oil-air mist is disclosed. A screw pump, preferably an assembly of components comprising a ring, a teflon seal, a pump rotor and a hub is secured onto a rotor shaft of a generator for rotation therewith. The rotor shaft has at least one passageway extending radially from an axial bore therein through which oil is transferred. The screw pump has a first orifice coincident with the rotor shaft passageway, a second orifice, a passageway extending from the first orifice to the second orifice through which the oil is directed into a cavity in the generator housing where it mixes with air to form a mist to lubricate the bearing, a circumferential surface fitting within an opening in the generator housing, and a helical groove in the circumferential surface through which the oil-air mist is evacuated during rotation of the generator rotor shaft.
