Exhaust gas turbocharger, particularly for internal combustion engine of motor vehicle, has bearing housing for supporting rotor shaft and compressor housing for receiving compressor wheel

摘要

The exhaust gas turbocharger (1) has a bearing housing (3) for supporting a rotor shaft (4) and a compressor housing for receiving a compressor wheel (6). A compressor housing-rear wall (7) is arranged between the bearing housing and the compressor housing, in order to disconnect an oil chamber (8) of the bearing housing from a wheel back gap (10) that is formed between the compressor housing-rear wall and a wheel back (9) of the compressor wheel. A clamping unit (12) has a counter-engagement section (13) and a head section (14). An independent claim is also included for a method for mounting an exhaust gas turbocharger.
