  • Method and apparatus for supporting rotor assembly bearings
    Patent number: 6439772
    Abstract: A rotor assembly for a gas turbine engine including a bearing assembly and a damper sub-assembly that facilitate reducing dynamic motion to the rotor assembly is described. The bearing assembly includes rolling elements positioned between a paired race. The rotor assembly includes a rotor shaft supported by the bearing assembly. The damper sub-assembly is radially outward from the bearing assembly adjacent a sump housing, and includes a damper insert. A predetermined preload force is applied to the rolling elements. An outer race of the bearing assembly distorts to substantially match a distortion pattern of the damper insert.
