A bearing bush of a turbocharger for radially mounting a shaft of the turbocharger. The bearing bush on an inner surface facing the shaft to be mounted, which forms a running surface of the bearing bush, has a microstructuring of multiple cup-shaped recesses at least in sections. The recesses have a maximum depth.

Bearing bush of a turbocharger and turbocharger

A turbocharger, has a turbine for expanding a first medium and a compressor for compressing a second medium. The turbine includes a turbine housing and a turbine rotor. The compressor includes a compressor housing and a compressor rotor coupled to the turbine rotor via a shaft. A bearing housing is arranged between the compressor and turbine housings in which the shaft is mounted. The turbine and bearing housings are connected via a fastening device mounted on a flange of the turbine housing with a first section and a second section that covers a flange of the bearing housing at least in sections. The fastening device is contoured curved on a surface of the second section facing the flange of the bearing housing.

Turbocharger

A turbocharger, with a turbine and compressor housing connected to a bearing housing. An inflow housing of the turbine and bearing housing are connected via a fastening device mounted to a flange of the inflow housing with a first section and partially overlaps a flange of the bearing housing with a second section. Between the inflow housing and the bearing housing, flanges of a nozzle ring and of a sealing cover are clamped. Adjoining surfaces contacting one another in a region of a first, second, and/or a third contact clamping region are hardened.
