Patent attributes
A bearing assembly comprises a housing that includes a first housing surface and a second housing surface. The first and second housing surfaces are substantially axially parallel with respect to a rotor centerline. The bearing assembly also comprises a damped outer race that includes a first outer race surface radially adjacent to and opposing the first housing surface which is located radially interior to the first outer race surface. A second outer race surface is radially adjacent to and opposing the second housing surface which is located radially exterior to the second outer race surface. The housing comprises an oil passage that is configured to provide oil from an outlet to a first space between the first outer race surface and the first housing surface, and configured to provide oil to a second space radially between the second outer race surface and the second housing surface.
