ABSTRACT:
A bearing carrier for high speed rotating machinery, such as a turbocharger, wherein lubricant is supplied under pressure and is drained by gravity. The primary feature is the forming of the bearing housing with a very large drain chamber which is obstructed only by a lubricant supply boss supporting a central housing portion in which a sleeve bearing is resiliantly mounted. Lubricant exiting from the ends of the sleeve bearing is flung circumferentially away from the rotating components and drains naturally to a lower portion of the drain chamber where it flows through a drain passage port without re-entering the rotating components or piston ring seal area. The drain port is so positioned with respect to the lubricant drain chamber and there is provided a dam around the seal area at the axial end of the lubricant drain chamber whereby the machinery may be selectively positioned with the shaft horizontal, within 10.degree. from the vertical or in intermediate positions and whereby there is effective draining of the lubricant from the machinery without flooding of the seals between the rotating components and the housing which would cause undue lubricant loss along the shaft.
