Turbocharger
A turbocharger, with a turbine for expanding a first medium and a compressor for compressing a second medium. The turbine has a turbine housing with a turbine inflow housing and a turbine rotor. The compressor has a compressor housing and a compressor rotor coupled to the turbine rotor via a shaft. The turbine housing and the compressor housing are connected to a bearing housing in which the shaft is mounted. The turbine inflow housing and the bearing housing are connected at flanges adjoining one another via fastening devices such that the flange of the turbine inflow housing, through which the fastening devices extend extends axially spaced as far as into the range of extent of the turbine rotor.
1 . A turbocharger comprising:
a shaft;
a turbine configured to expand a first medium, comprising:
a turbine inflow housing;
a turbine inflow housing flange;
a turbine housing with the turbine inflow housing; and
a turbine rotor;
a compressor configured to compress a second medium utilising energy extracted in the turbine during the expansion of the first medium; the turbine, comprising:
a compressor housing; and
a compressor rotor coupled to the turbine rotor via the shaft; and
a bearing housing arranged between the turbine housing and the compressor housing and having a bearing housing flange and in which the shaft is mounted and to which the turbine housing and the compressor housing are connected;
wherein the turbine inflow housing and the bearing housing are connected to one another at their respective flanges adjoining one another via fastening devices such that the turbine inflow housing flange through which the fastening devices extend, extends seen in a radial direction axially spaced as far as into a range of extent of the turbine rotor.
2 . The turbocharger according to claim 1 , wherein the turbine rotor covers the turbine inflow housing flange through which the fastening devices extend at least in sections.
3 . The turbocharger according to claim 2 , wherein the turbine rotor covers the fastening devices at least in sections.
4 . The turbocharger according to claim 3 , wherein moving blades of the turbine rotor cover the fastening devices at least in sections.
5 . The turbocharger according to claim 1 , wherein the fastening devices starting out from the turbine inflow housing flange extend into the bearing housing flange.
6 . The turbocharger according to claim 1 , wherein in an axial direction seen from the turbine in a direction of the bearing housing the turbine inflow housing flange, through which the fastening devices extend, is arranged behind the turbine rotor and in front of the bearing housing flange, into which the fastening devices extend.
7 . The turbocharger according to claim 1 , wherein the turbine is a radial turbine.
