Abstract
A bearing includes a bearing pad for supporting a rotary component and a housing attached to or formed integrally with the bearing pad. The housing defines a first fluid damper cavity positioned adjacent to the bearing pad and a second fluid damper cavity spaced from the first fluid damper cavity. The first and the second fluid damper cavities are in restrictive flow communication. The housing is configured to transfer a fluid from the first fluid damper cavity to the second fluid damper cavity in response to a force acting on the bearing pad to dampen a movement of the bearing pad.

A bearing comprising:
- a bearing pad for supporting a rotary component;
- and
- a housing attached to or formed integrally with the bearing pad, the housing defining
- a first fluid damper cavity positioned adjacent to the bearing pad;
- and
- a second fluid damper cavity spaced from the first fluid damper cavity and in restrictive flow communication with the first fluid damper cavity, the housing configured to transfer a fluid from the first fluid damper cavity to the second fluid damper cavity in response to forces acting on the bearing pad.
A bearing for a gas turbine engine comprising a rotary component, the bearing comprising:
- a bearing pad for supporting the rotary component of the gas turbine engine;
- and
- a housing comprising a serpentine wall attached to or formed integrally with the bearing pad, the serpentine wall at least partially defining a first fluid damper cavity positioned adjacent to the bearing pad and at least partially defining a second fluid damper cavity, the first fluid damper cavity in restrictive flow communication with the second fluid damper cavity.
