Benefits of technology

This patent is about a new type of turbocharger that solves the problem of ensuring the safe and reliable mounting of the shaft in the bearing housing, particularly adjoining the turbine. The technical effect of the invention is the creation of a swirl chamber that is open in the direction of the bearing ring or the bearing bush in the end disc of the turbocharger. This allows for the safe and calmed collection and discharge of oil that leaks from the lubrication gap of the bearing, increasing the operational safety of the turbocharger with simple elements. Additionally, the swirl chamber is designed with a closed axial wall and radial walls, as well as a web that defines a sealing gap to the shaft, for optimal oil collection.

Problems solved by technology

Especially on the hot turbine side there is the risk that oil leaking from the bearing housing can ignite.

Embodiment Construction

[0016]FIG. 1 shows the fundamental construction of a turbocharger 1. A turbocharger 1 comprises a turbine 2 for expanding a first medium, in particular for expanding exhaust gas of an internal combustion engine. Furthermore, a turbocharger 1 comprises a compressor 3 for compressing a second medium, in particular charge air, namely utilising energy extracted in the turbine 2 during the expansion of the first medium.

[0017]The turbine 2 comprises a turbine housing 4 and a turbine rotor 5. The compressor 3 comprises a compressor housing 6 and a compressor rotor 7. The compressor rotor 7 is coupled to the turbine rotor 5 via a shaft 8, which is mounted in a bearing housing 9. The bearing housing 9 is positioned between the turbine housing 4 and the compressor housing 5 and is connected to both the turbine housing 4 and the compressor housing 5.

[0018]The turbine housing 4 of the turbine 2 comprises an inflow housing 11 and an outflow housing 12. By way of the inflow housing 11, the first ...

Abstract

A turbocharger, having a turbine with a turbine housing and a turbine rotor, (a compressor with a compressor housing and a compressor rotor that is coupled to the turbine rotor via a shaft, a bearing housing arranged between the turbine housing and the compressor housing, in which the shaft is mounted via a bearing. An end disc adjoins the bearing ring or the bearing bush. On an axial surface facing the bearing ring or the bearing bush of the bearing facing the turbine, a swirl chamber that is open in the direction of the bearing ring or the bearing bush is introduced into the end disc, which collects and discharges oil leaking from a lubrication gap of the bearing.

Description

BACKGROUND OF INVENTION1. Field of the Invention[0001]The invention relates to a turbocharger.2. Description of Related Art[0002]The fundamental construction of a turbocharger is known to a person skilled in the art addressed here. A turbocharger comprises a turbine in which a first medium is expanded. Furthermore, a turbocharger comprises a compressor in which a second medium is compressed, utilising energy extracted in the turbine during the expansion of the first medium. The turbine of the turbocharger comprises a turbine housing and a turbine rotor. The compressor of the turbocharger comprises a compressor housing and a compressor rotor. Between the turbine housing of the turbine and the compressor housing of the compressor a bearing housing is positioned. The bearing housing is connected on the one hand to the turbine housing and on the other hand to the compressor housing. In the bearing housing a shaft is mounted via which the turbine rotor is coupled to the compressor rotor....
