Apparatus and methods of self cooling a vertical motor thrust bearing

摘要

Vertical motors having a thrust bearing and an oil deflector positioned in an oil sump in which the thrust bearing is located are disclosed. Oil flowing through the thrust bearing may be spread across the oil deflector and directed down along an inside surface of a wall of the oil sump to allow the oil to cool. The oil deflector may be polished sheet metal. In some embodiments, a plurality of fins may be arranged around an outside surface of the wall to provide additional heat exchange. A fan may additionally be provided to direct air flow between the plurality of fins to further facilitate the heat exchange. Methods of cooling a thrust bearing in a vertical motor are also provided, as are other aspects.

主权项

1. A vertical motor, comprising:
a thrust bearing; an oil sump in which the thrust bearing is located, the oil sump having a wall and containing oil filled to an oil level, the thrust bearing at least partially immersed in the oil; and an oil deflector positioned in the oil sump, the oil deflector having an inside portion located proximate to the thrust bearing and an outside portion located proximate to the wall, and an upper portion positioned above the oil level, the outside portion configured to create a gap between an outer surface of the outside portion and an inside surface of the wall, the oil deflector configured to guide oil received from the thrust bearing over the upper portion and into the gap.
