    Abstract: A bearing housing (12) for a turbocharger having a rotatable shaft (14) passing through the bearing housing (12) with journal bearings (30) having flexure pivot tilting pads (40) for supporting the rotatable shaft (14) in the bearing housing (12). The flexure pivot tilting pads (40) may have oil supply holes (50) through each pad (40) to direct lubrication to each pad surface (44). The journal bearings (30) preferably have a circumferential groove (52) on an outer surface of the bearing aligned with the oil supply holes (50) to help feed oil to the oil supply holes (50).

    Abstract: A laser cutting device (100) is configured to etch an inner surface of a journal bearing (18). The laser cutting device (100) includes a laser (102); a beam directing tool (130) that receives a beam (108) emitted from the laser (102) and selectively changes the direction of travel of the beam (108); a fixture (170) that supports the journal bearing (18) in a desired position relative to the beam directing tool (130); an actuator (148) connected to one of the beam directing tool (130) and the fixture (170), the actuator (148) providing relative movement between the beam directing tool (130) and the fixture (170); and a controller (180) that controls the intensity and duration of the beam (108) emitted from the laser (102); and the actuator (148), whereby material can be removed from a surface of the journal bearing (18) to a precise width and depth, and in any pattern.

    Abstract: A turbocharger rotating assembly (125) includes a shaft (20) rotatably supported in a bearing housing (123) via bearings (26, 128), a compressor impeller (18) mounted on the shaft (20), and an oil flinger (122) disposed on the shaft (20) between the bearings (26, 128) and the compressor impeller (18). The turbocharger (100) further includes an insert (134) disposed in the shaft-receiving axial bore (120) so as to surround the oil flinger (122), and a purge seal (160) operatively positioned in an interface (131) between the insert (134) and the oil flinger (122), whereby the purge seal (160) is configured to minimize oil passage from the bearing housing (123) into the interface (131). An annular cavity (150) encircles the radially outward-facing surface (138) of the insert (134), the cavity (150) forming a portion of a fluid path configured to deliver pressurized fluid to the interface (131).
