Abstract
Turbochargers operate at extremely high speed, so balance of the rotating core is of the utmost importance to turbocharger life. A special frusto-conical, or frusto-spherical, centering geometry is added to the interface of the compressor nut and the nose of the compressor wheel to aid in keeping the wheel, nut, and stub-shaft centered on the turbocharger axis to reduce the degree of core unbalance.
