An assembly for use in a bearing compartment having an axis includes a bearing outer race configured to be located in the bearing compartment. The assembly further includes at least one annular spring positioned in the bearing outer race and being asymmetric in at least one of the axial direction or the circumferential direction relative to the axis to reduce the likelihood of amplification of vibration experienced by the at least one annular spring.

Asymmetry in annular centering spring

A sleeve for a bearing damper comprising a cylinder shaped body having a forward end opposite an aft end, the body including an interior surface opposite an exterior surface, the body configured insertable between a bearing proximate the interior surface and a housing proximate the exterior surface; a ring portion proximate the forward end, the ring portion having an outer diameter larger than a diameter of the body; and an extension portion configured to provide an active damper surface extending beyond the housing.

A bearing support may include a central shaft, a flange shaft, and a tube boss. The central shaft may include a central longitudinal axis extending between a first end and a second end of the bearing support. The flange shaft may extend radially outward of the central shaft at an acute angle, relative to the central longitudinal axis from the first end to the second end, and the flange shaft may include a rim defining an aperture. The tube boss extends from the central shaft radially outward through the aperture, according to various embodiments. An annular channel may be between the rim and the tube boss.
