摘要： A turbocharger assembly (200) includes a compressor wheel (240) with a base surface (244), a nose surface (242), a z-plane disposed between the base surface and the nose surface and a bore (245) extending from the base surface to the nose surface and a shaftt (220) hat includes a first pilot surface (PA) disposed in the bore of the compressor wheel at a position between the z-plane and the nose surface, a second pilot surface (PB) disposed in the bore of the compressor wheel at a position between the z-plane and the base surface, and a recessed surface (225) disposed between the first pilot surface and the second pilot surface. Such an assembly can include a nut (270) adjustably disposed on the shaft adjacent to the nose surface of the compressor wheel where adjustment of the nut tensions the shaft to apply a compressive load between the base surface and the nose surface of the compressor wheel.

摘要： A sealed shaft assembly (670) includes a component of a turbocharger (120) that includes a bore (607) that extends between an inner, exhaust gas side of the component and an outer, ambient side of the component; a shaft (671) that includes a pin (676) portion and a head portion (673); a sleeve (692) positioned on the pin portion of the shaft; and a bushing (694) positioned over at least part of the sleeve and over at least part of the head portion of the shaft where the bushing seats the shaft and the sleeve in the bore (607). During operation of a turbocharger (120) that includes such an assembly (670), the shaft, the sleeve and the bushing restrict flow of exhaust gas from the inner, exhaust gas side of the component to the outer, ambient side of the component.
