Turbocharger having a nozzle ring centered by a guiding projection
First Claim
1. A turbocharger comprising:
- a turbine configured for expanding a first medium, the turbine comprising;
a turbine housing; and
a turbine rotor rotatably mounted within the turbine housing,wherein the turbine housing comprises;
an inflow housing;
a nozzle ring mounted within the inflow housing and having guide blades for controlling flow of the first medium from the turbine rotor;
an axially extending stepped projection arranged on the nozzle ring; and
an insert piece that delimits a flow duct of the inflow housing;
a shaft;
a compressor configured for compressing a second medium utilizing energy extracted in the turbine during the expansion of the first medium, the compressor comprising;
a compressor housing; and
a compressor rotor rotatably mounted within the compressor housing, the compressor rotor being coupled to the turbine rotor by the shaft; and
a bearing housing positioned between, and connected to, the turbine housing and the compressor housing, the shaft being mounted within the bearing housing, the bearing housing having an axially groove having a radially extending step,wherein the nozzle ring is centered about the shaft and radially guided onto the bearing housing by the stepped projection that mates with the stepped axial groove of the bearing housing.

Abstract
A turbocharger (1), having a turbine (2) for expanding a first medium, having a compressor (3) for compressing a second medium utilizing energy extracted in the turbine (2) during the expansion of the first medium, wherein the turbine (2) has a turbine housing (4) and a turbine rotor (5). The compressor (3) has a compressor housing (6) and a compressor rotor (7) that is coupled to the turbine rotor (5) via a shaft (8). The turbine housing (4) and the compressor housing (6) are each connected to a bearing housing (9) arranged there between, in which the shaft (8) is mounted. The turbine housing (4) has an inflow housing (11), a nozzle ring (15) with guide blades (16) and an insert piece (13). The nozzle ring (15) is centered and radially guided by a projection (17) on the bearing housing (9).
