Rotor for radial flow machine, has intermediate element that is arranged between symmetric surface of shaft and impeller

摘要

The rotor (R) has a shaft (SH) provided with a symmetric surface (SF). An impeller (IM) is attached to an end face (FF1) of shaft by a torque-transmitting connection unit (TC). An intermediate element (IE1) is arranged between a symmetric surface of shaft and the impeller. An expansion screw (TS) is extended parallel to a longitudinal axis (AX) of impeller and shaft.
