Abstract
Dynamically-lubricated bearings and methods of dynamically lubricating bearings, including bearings used in gas turbine engines. Such a bearing includes an inner race having an inner race groove between a pair of inner race cage lands, an outer race having an outer race groove between a pair of outer race cage lands and opposes the inner race groove, rolling elements disposed between the inner and outer races and in rolling contact with the inner and outer race grooves, and a cage disposed between the inner and outer races to maintain separation between the rolling elements. A lubricant is introduced into a cavity between the inner and outer races, and rotation of the inner race relative to the outer race causes the lubricant to exit the cavity through recessed surface features in at least one of the inner and outer race cage lands.
