SUPPLEMENTARY COOLING SYSTEM FOR THRUST BEARING Abstract of the Disclosure Apparatus for providing supplementary cooling to the thrust bearing of a vertical shaft machine, without requiring an additional exterior pump and motor, has an oil conducting path formed by grooves in the engaging surfaces of an upper and a lower portion of each bearing shoe. The oil conducting path terminates at an opening on either side of the outer periphery of the shoe. A nozzle is mounted in each opening. The nozzle extends upwardly with a horizontally extending nose portion with the nozzle opening in the end. The nose portion is adjacent the outer periphery of the rotating bearing ring which the shoes support. The ring is mounted to the vertical shaft. The shoes and the ring are immersed in an oil path. Rotation of the shaft and the ring moves the oil adjacent the periphery of the ring. The nozzles are oriented in opposite directions, preferably facing one another. The oil caused to move by the rotating ring enters the opening in the end of one nozzle, moves through the oil conducting path, and exits from the other nozzle in the direction of oil movement. The apparatus provides supplementary cooling by oil circulation regardless of the direction of rotation.
