ABSTRACT:
A thrust bearing assembly for use in an exhaust gas turbocharger or the like, and which includes a holding plate fixed to the turbocharger housing, a shaft rotatably mounted in the housing and extending through an opening in the plate, and a pair of flat, annular rings mounted on the shaft and receiving the plate therebetween to define a pair of opposing bearing surfaces on each side of the plate. A lubrication system supplies pressurized lubricant to the opposing bearing surfaces, and at least one of each pair of opposing bearing surfaces includes a plurality of generally radially directed channels, whereby a hydrodynamic load bearing pressure is developed in the lubricant between the bearing surfaces during relative rotation thereof, to thereby minimize frictional resistance and wear.
