Bearing system with bearing damper

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.

What is claimed is: 
     
         1 . A method for using oil from a bearing to cool or lubricate a component axially spaced from the bearing, comprising:
 receiving oil in an annular gap between a bearing and a structure;   directing the oil exiting from the annular gap to at least one outlet oriented toward the component; and   exhausting the oil via the at least one outlet for the oil to project onto the component.   
     
     
         2 . The method according to  claim 1 , wherein receiving the oil in the annular gap comprises receiving the oil from an oil reservoir. 
     
     
         3 . The method according to  claim 1 , further comprising restricting the oil from exiting the annular gap to form a bearing damper between the bearing and the structure. 
     
     
         4 . The method according to  claim 1 , wherein directing the oil exiting from the annular gap comprises directing oil against a seal delimiting the annular gap to press the seal against a surface forming the annular gap. 
     
     
         5 . The method according to  claim 1 , wherein exhausting the oil comprises projecting the oil at least partially axially. 
     
     
         6 . The method according to  claim 1 , wherein exhausting the oil via the at least one outlet comprises projecting the oil onto a seal runner.
