ABSTRACT:
An exhaust-gas turbocharger has a bearing system which is positioned between a compressor impeller and a turbine wheel which are positioned on respective ends of a rotor shaft. The compressor impeller is attached to the rotor-shaft via an intermediate bush. A conically mating fit, at one end of the intermediate bush directly adjacent to the bearing, serves to attach this intermediate bush to a shaft-stub of the rotor shaft. A frictionally-locked press fit serves, at the other end of the intermediate bush, to attach the compressor impeller to the intermediate bush, in a manner which transmits torque.
