Abstract (en)
A compressor wheel assembly for example for a turbocharger comprises a compressor wheel (12) including a boreless hub (14) formed integrally as by casting from aluminium with a circumferential array of aerodynamically contoured centrifugal impeller blades (16). The wheel hub is secured at its base by inertia welding to a steel thrust spacer sleeve (18) having an internally threaded bore (34) for threaded reception of a rotatable shaft (20). In use of the compressor wheel assembly, the absence of a bore within the wheel hub substantially improves wheel fatigue life.
