ABSTRACT:
An improved compressor wheel assembly for a a turbocharger or the like includes a centrifugal compressor wheel having a boreless hub to substantially improve wheel fatigue life. The compressor wheel is formed as by casting from an aluminum alloy to include an integral mounting sleeve extending coaxially from the boreless hub and adapted for connection as by threading with a turbocharger shaft. An annular spacer ring of wear resistant material is mounted on the wheel mounting sleeve and defines wear resistant surfaces for supporting one or more seal rings within the bore of a compressor backplate opening, and for axially engaging an adjacent thrust bearing unit associated with the turbocharger shaft.
