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： An object is to provide a centrifugal compressor in which an axial force applied from a shrink-fit impeller to a sleeve section is ensured even if the sleeve section is separated from a clamp surface in an axial direction of an attachment hole, as well as a turbocharger provided with the centrifugal compressor and a method of producing the centrifugal compressor. An inner peripheral surface of an attachment hole formed on a hub includes a clamp surface and a diameter-widening surface, and an outer peripheral surface of a sleeve section includes a diameter-reducing surface. The diameter-widening surface and the diameter-reducing surface respectively include an impeller-side contacting portion and a sleeve-side contacting portion which contact each other, and a relationship represented by an expression θs
