Abstract
Lubricant for support bearings in a bearing housing on a vertical rotating shaft is supplied by a rotating impeller mounted on the shaft which includes a dip ring extending into an annular oil reservoir to draw oil upward to the impeller. A passageway from the impeller to a space above an uppermost one of the support bearings enables the lubricant to flow over the bearings and back to the rotating impeller for recirculation. A heat exchanger may be included to cool the lubricating liquid.
