A support assembly for a bearing of a gas turbine engine including a spring finger ring positioned radially exterior to an outer race of the bearing. The spring finger ring includes an outer ring positioned radially exterior to the outer ring, an inner ring positioned radially interior to the outer ring, and a plurality of spring fingers extending between the inner and outer rings. One or more spring fingers configured as two-sided spring fingers including a first ligament coupled to the outer ring and extending at a first circumferential angle to a first radial bumper proximate to the inner ring and a second ligament coupled to the inner ring and extending at a different second circumferential angle to a second radial bumper proximate to the outer ring. The first and second radial bumpers define first and second radial gaps between the bumpers and the inner and outer rings, respectively.

A damper assembly includes a bearing assembly including a bearing outer race. A damper inner race is spaced from the bearing outer race and includes a plurality of circumferentially-spaced first openings. The damper assembly also includes a damper outer race spaced from damper inner race and a plurality of damper segments extending between the damper inner race and the damper outer race. Each damper segment includes a plurality of second openings.

Squeeze film damper assemblies

Squeeze film damping systems and methods therefore are provided that include features for optimizing the damping response to vibrational loads experienced by a rotary component of a gas turbine engine. In one exemplary aspect, a damping system actively controls a dynamic sleeve to adjust the damping response. In particular, the dynamic sleeve is disposed within a chamber defined by a damper housing. The damping system controls the damper gap by translating the dynamic sleeve. When the dynamic sleeve is translated, a variable damper gap is varied, allowing for fluid to squeeze into or out of the damper gap, thereby adjusting the damping response to the vibration of the rotary component.

A bearing assembly for use in a rotating machine includes a housing and a retention nut threadably coupled to the housing and including a first retention mechanism. The bearing assembly also includes a retention bolt coupled to the housing and including a second retention mechanism configured to engage the first retention mechanism to maintain engagement of the retention nut with the housing.
