The invention relates to a rotor (1) for an exhaust gas turbocharger (2), having a turbine impeller (5), a radial sealing section (6) which adjoins the turbine impeller (5) on the compressor side and is fixed in rotation with the turbine impeller (5) and by means of which a bearing recess (7) of a casing (3) of the exhaust gas turbocharger (2) can be sealed on the turbine side, and a rotor shaft (8) adjoining the radial sealing section (6) on the compressor side and fixed in rotation with the radial sealing section (6). In order to provide a rotor (1) for an exhaust gas turbocharger (2) having improved temperature resistance, the invention proposes that the radial sealing section (6) or the turbine impeller (5) is connected to the rotor shaft (8) by means of a screw connection (9), wherein the screw connection (9) is arranged at least in part on the compressor side with respect to a sealing region of the radial sealing section (6). |
