    Abstract: The present disclosure is directed to a gas-lubricated bearing assembly for a gas turbine engine and method of damping same. The bearing assembly includes a bearing pad for supporting a rotary component and a bearing housing attached to or formed integrally with the bearing pad. The bearing housing includes a first fluid damper cavity, a second fluid damper cavity in restrictive flow communication with the first fluid damper cavity via a restrictive channel configured as a clearance gap, and a damper fluid configured within the first and second fluid damper cavities. More specifically, the damper fluid of the present disclosure is configured to withstand the high temperature environment of the engine. Thus, the bearing housing is configured to transfer the damper fluid from the first fluid damper cavity to the second fluid damper cavity via the restrictive channel in response to a force acting on the bearing pad.

    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 includes a flexible column extending towards the bearing pad for providing the bearing pad with an airflow. The column supports the bearing pad from a location inward of an outer periphery of the bearing pad along an axial direction of the bearing. With such a configuration, a resistance of the bearing pad along a radial direction of the bearing is less at the outer periphery than a resistance of the bearing pad along the radial direction proximate the column.

    Abstract: A bearing cage for a roller bearing assembly includes an annular body defining a circumferential centerline extending therethrough. The annular body includes an outer circumferential surface, an opposing inner circumferential surface, and a plurality of circumferentially spaced roller cavities defined therein. Each roller cavity of the plurality of roller cavities is configured to receive an associated roller element. Each roller cavity includes a first radial cross-wall defined within the annular body extending from the outer circumferential surface to the inner circumferential surface. Each roller cavity further includes an opposing second radial cross-wall defined within the annular body extending from the outer circumferential surface to the inner circumferential surface. At least a portion of the first radial cross-wall and at least a portion of the second radial cross-wall are complimentary to the associated roller element.

    Abstract: In one aspect, a dual pitch bearing configuration for coupling a rotor blade to a hub of a wind turbine. The dual pitch bearing configuration including a first pitch bearing and at least one additional pitch bearing disposed axially a distance LB from the first pitch bearing. The dual pitch bearing configuration further including one or more spacers disposed between the first pitch bearing and the at least one additional pitch bearing and extending the distance LB. The dual pitch bearing disposed radially within one of a blade root of the rotor blade, a hub extension or a bearing housing and coupled thereto. The dual pitch bearing configuration minimizing moment loading on the first pitch bearing and the at least one additional pitch bearing. A wind turbine including the dual pitch bearing configuration is further disclosed.
