Abstract:
A bearing system comprises a bearing configured to be mounted to a shaft. A bearing housing interfaces the bearing to a structure. An annular gap is defined between an outer annular surface of the bearing housing and the structure and configured to receive oil therein. An outlet defined in an outer section surface of the bearing housing is oriented toward a component axially spaced from the bearing. A fluid passageway between the at least one outlet and the annular gap for fluid communication therebetween. In use the fluid passageway directs pressurized oil from the annular gap to the outlet to reach the adjacent component. A method for using oil from a bearing to cool or lubricate a component axially spaced from the bearing is also provided.
