Abstract
A thrust bearing for constraining axial movement of the shaft of a turbocharger is made from two separate components which are assembled together, thereby simplifying manufacturing since no drilling is required. The components each include cooperating contoured surfaces for forming the oil feed holes which extend between the working surfaces of the thrust bearing, the oil feed passages, which communicate oil to the oil feed holes, and an oil gallery, which communicates oil to the oil feed passages. The oil gallery is entirely internal to the turbocharger, thereby minimizing oil side leakage. The gallery is fed from the turbocharger lubricating oil supply through an aperture extending through one of the sides of the thrust bearing in communication with the gallery.
