Method And Apparatus For Supporting Rotor Assembly Bearings

US Patent:
2002006, Jun 6, 2002
Filed:
Dec 1, 2000
Appl. No.:
09/728796
Inventors:
Peter Ommundson - North Andover MA, US
Robert Brown - Medford MA, US
Scott Tardanico - Littleton MA, US
International Classification:
F16C027/04
US Classification:
384/099000, 384/581000
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.
