FLEXIBLY COUPLED DUAL SHELL BEARING HOUSING

摘要

PROBLEM TO BE SOLVED: To provide a rotor bearing of a gas turbine engine. SOLUTION: A bearing housing 34 includes inside and outside shells 36 and 38 through which a rotor shaft 30 extends. A supply pipe 50 is fixedly joined to the inside shell 36 and extends passing through a supply opening 62 of the outside shell 38. At the opening 62, the supply pipe 50 is sealingly joined to the outside shell 38 so that a flexible joint 64 enables differential temperature movement between the shells 36 and 38 in the supply pipe 50.
