A rotor for at least one of a turbine and a compressor of a supercharging device may include a shaft defining an axis of rotation and at least one impeller. The at least one impeller may have a thread which is arranged coaxially to the axis of rotation. The shaft may include a complementary thread which is arranged coaxially to the axis of rotation. The shaft and the at least one impeller may be secured together via the respective threads. The shaft and the at least one impeller may be fixed with respect to one another via at least one of a soldered connection, a welded connection, an adhesive bond, a clamped connection and a crystallization connection.

Rotor for a turbine or a compressor or a turbine/compressor geometry

The invention relates to a charging device, more preferably an exhaust gas turbocharger for a motor vehicle with a variable turbine/compressor geometry () with a plurality of adjustable guide blades, which are each engaged with an adjusting ring () via a corresponding lever (') and which are preferentially jointly adjustable through said adjusting ring. Through a reinforcement () of a plurality of engagement regions (&#x2032;) of the adjusting ring () which are in contact with an adjusting lever (&#x2032;) each, higher force transmission from the adjusting ring () to the adjusting levers (&#x2032;) is made possible without disadvantageous plastic deformation of the adjusting ring () or of the adjusting levers (&#x2032;).
