Charging device, particularly exhaust gas turbocharger of internal combustion engine, comprises bearing housing for supporting rotor, where bearing housing is formed as composite component and has compressor section or light metal

摘要

The charging device (1) comprises a bearing housing (2) for supporting a rotor (3). The bearing housing is formed as a composite component and has a compressor section (7) that is made of plastic or light metal, such as aluminum or magnesium and turbine section (6) made of metal. The turbine section has a water jacket (13) extending in the circumferential direction and surrounds the rotor in a ring-shaped manner. The compressor section is formed as a plastic injection-molded portion. A bearing sleeve (30) is provided, which is arranged in the compressor section of the bearing housing.
