Abstract:
1. A turbocharger comprising: a turbine wheel; a compressor wheel; a center housing that comprises a through bore, extending from a compressor end to a turbine end along a bore axis, and a recess, adjacent the through bore, in a plane orthogonal to the bore axis wherein the through bore comprises an inner diameter and wherein the recess comprises a two dimensional shape, in the plane orthogonal to the bore axis, that extends an axial depth; a ball bearing cartridge positioned in the through bore that comprises an outer race that comprises a keyway and an outer diameter wherein the inner diameter of the through bore and the outer diameter of the outer race define a radial clearance for radial movement of the ball bearing cartridge in the through bore; an anti-rotation component seated at least partially in the recess and at least partially in the keyway to restrict rotational movement of the outer race of the ball bearing cartridge in the through bore by contact between the outer race and the anti-rotation component and the anti-rotation component and the center housing; and a plate that covers at least a portion of the anti-rotation component.
