Abstract
A supercharging device, for example an exhaust gas turbocharger, may include a rotor mounted in a housing via an axial bearing. The axial bearing may include an axial bearing disc, a membrane, and a screw connection that secures the axial bearing disc to the membrane through an opening in the membrane. The axial bearing may further include a bush connected to the housing. The membrane may be clamped in between the bush and the housing. An adjusting screw may be inserted into an opening of the bush. The adjusting screw may delimit and/or facilitate an axial movement of the screw connection and the axial bearing disc.
Claims20
A supercharging device comprising:
- a rotor mounted in a housing;
- the rotor mounted in the housing via an axial bearing disposed on an end side of the rotor;
- the axial bearing including:
- an axial bearing disc with a first bearing surface;
- a membrane with a central first opening;
- a screw connection that secures the axial bearing disc to the membrane through the central first opening;
- a bush with a central second opening, wherein the bush is connected to the housing and the membrane is clamped in between the bush and the housing;
- and
- an adjusting screw screwed into the central second opening of the bush, wherein the adjusting screw delimits and facilitates an axial movement of the screw connection and the axial bearing disc.
An exhaust gas turbocharger, comprising:
- a rotor defining a rotation axis;
- a housing;
- an axial bearing disposed on an axial end side of the rotor with respect to the rotation axis, the rotor mounted in the housing via the axial bearing, the axial bearing including:
- an axial bearing disc having a first bearing surface;
- a membrane having a central first opening;
- a screw connection that secures the axial bearing disc to the membrane through the central first opening;
- a bush having a central second opening, wherein the bush is connected to the housing and the membrane is clamped in between the bush and the housing;
- and
- an adjusting screw disposed in the central second opening of the bush, wherein the adjusting screw delimits and facilitates an axial movement of the screw connection and the axial bearing disc.
