ABSTRACT:
A double tilting pad journal bearing includes a substantially cylindrical, open ended beating casing having a longitudinal axis extending therethrough, an interior surface of which supports a plurality of beating liner pads for circumferential and axial tilting movement relative to the casing and to the longitudinal axis. The casing is formed with a pair of annular oil feed grooves in the exterior surface thereof communicating with the interior of the bearing casing by a plurality of radially directed feed passages. The interior surface is also formed with at least one oil drain annulus in communication with at least one radially oriented drain port. Annular seals are fitted within grooves at opposite ends of the bearing casing. The bearing liner pads are secured within the casing by a sliding tongue and groove fit which nevertheless permits tilting of the pads both circumferentially and axially. Locking pins are used to hold the bearing liner pads in proper circumferential orientation within the bearing casing.
