A turbocharger impeller has a lock ring that is flexed in assembly to clampingly center and lock an impeller wheel on its drive shaft. The lock ring is also applicable to other driving or driven shaft and wheel combinations. The lock ring is made part of a two-piece spacer for the illustrated rotor applications but is not limited to that arrangement. Alternative impeller wheel structures including drive means and locking nose cone features are included.
