Charging device, particularly exhaust gas turbo charger, has rotor which is supported by combined axial or radial bearing unit in bearing housing

摘要

The charging device has a rotor (1) which is supported by a combined axial or radial bearing unit (2) in a bearing housing (3). The axial or radial bearing unit has an axial or radial bearing (4) and an appropriate counter bearing. The axial or radial bearing has an axially adjustable switching element (6) which is arranged in bearing housing. A spring unit (8) pressurizes the switching element in the direction of the rotor.
