Abstract
A tilt pad journal bearing for supporting a rotating shaft includes an annular support ring and a plurality of arcuate pads tiltably mounted in the annular support ring and circumferentially spaced apart from each other. The tilt pad journal bearing further has a lubrication arrangement disposed between each pair of the plurality of arcuate pads. The lubrication arrangement includes a lubrication manifold connected to the annular support ring and recessed relative to a shaft support surface of adjacent arcuate pads to define an oil mixing cavity, and a plurality of lubrication nozzles protruding from the lubrication manifold into the oil mixing cavity. A cross-sectional flow area of at least one of the plurality of lubrication nozzles positioned toward a center of the lubrication manifold is larger than a cross-sectional flow area of a remainder of the plurality of nozzles.
