Exhaust gas turbocharger for internal-combustion engine of motor vehicle, has bearing arrangement with cone bearings e.g. hydrodynamic sliding bearings that are axially spaced from each other and have opposite tapers

摘要

The turbocharger (1) has a rotor (2) rotatably supported in a stator (3) around a rotational axis (4) by a bearing arrangement (5). The bearing arrangement has cone bearings (10, 11) e.g. hydrodynamic sliding bearings, which are axially spaced from each other and have opposite tapers (12). The bearing arrangement has a common bearing bush (13) that coaxially encloses the rotor, where the bush is torque-proofly arranged at the stator. The arrangement has a cone (15) torque-proofly arranged at the rotor, where the cone has conical outer bearing surfaces (14, 17) turned away from the rotor.
