Abstract
A compressor wheel assembly for turbochargers and the like comprises a compressor wheel including a boreless hub formed integrally as by casting with a circumferential array of aerodynamically contoured centrifugal impeller blades. The wheel hub is secured at its base by inertia welding to a thrust spacer sleeve having an internally threaded bore for threaded reception of a rotatable shaft. In use of the compressor wheel assembly, the absence of a bore within the wheel hub substantially improves wheel fatigue life.
