加圧型ボールベアリングアッセンブリ

Title:

加圧型ボールベアリングアッセンブリ

Document Type and Number:

Japanese Patent JP3781774

Kind Code:

B2

Abstract:

A pressurized bearing assembly for turbomachines like gas turbine engines wherein pressurized oil is used to apply an axial force to the outer bearing race of a ball bearing assembly. The force is transmitted through the race to the ball bearings and to the inner race of the bearing assembly, and is further transmitted, via the engine shaft, to the bearings of another, axially spaced apart bearing assembly. The force moves the balls in both assemblies into line-on-line running contact with their respective bearing races, and minimizes vibration in the assemblies.
