Problems solved by technology

However, in the fluid machine known from EP 1 233 190 A1 there is the danger that the flexible fixing of the inner housing insert on the outer helical housing fails during energy absorption due to tangentially acting forces
Fragments or parts of the compressor rotor can then be flung out and the reliability of the fluid machine's anti-leakage system can no longer be guaranteed

Embodiment Construction

[0018] The invention relates to details of fluid machines, in particular exhaust gas turbochargers, with a compressor housing consisting of an outer helical housing and an inner housing insert, wherein the inner housing insert is fixed by flexible and releasable parts, that is, fixed to the outer helical casing by bolted connections. A fluid machine for fastening an inner housing insert to an outer helical housing with flexible and releasable fixings is known from EP 1 233 190 A1, the content of which is expressly referred to here by reference. Refer below Figure 1-8 Essentially only the details are presented which distinguish the fluid machine according to the invention from the fluid machine disclosed in EP 1 233 190 A1.

Abstract

The invention relates to a fluid machine, in particular an exhaust gas turbocharger, with a radially flowing compressor rotor (2), which is sleeved on a shaft (1) supported in a bearing housing and arranged on a In the compressor casing with a worm-shaped fluid passage, the outer contour of the hub of the compressor rotor (2) and the inner contour of the compressor casing form a fluid passage guided from the axial direction to the radial direction, and the compressor casing is formed by an external spiral Shaped housing (5) and an inner housing insert (6), the outer helical housing (5) is fixed on the bearing housing by means of a rigid fixture, the inner housing insert (6) is arranged on the helical housing (5) And between the compressor rotor (2), and fixed on the spiral shell (5). The second fixing (8) for fixing the housing insert (6) to the helical housing (5) comprises at least one expansion fitting bolt (10) with a fitting bolt (12) of at least The fit is made in a flanged area or hole of the housing insert (6) and the helical housing (5) to absorb tangentially acting forces.

Description

technical field [0001] The invention relates to a fluid machine, in particular to an exhaust gas turbocharger. Background technique [0002] EP 1 233 190 A1 discloses a fluid machine according to classification. EP 1 233 190 A1 discloses a fluid machine in the form of a radial compressor, with a shaft supported in a bearing housing in its central longitudinal region, carrying a turbine and A compressor rotor with radial flow. The compressor rotor has a hub that is fitted in rotation on a shaft driven by a turbine, the circumferential side of which hub is equipped with radially spaced blades. The outer contour of the hub and the inner contour of the compressor housing delimit a fluid channel that narrows from the axial direction to the radial direction outwards, the cross section of which corresponds to the configuration of the blades. The compressor casing is fixed to the bearing housing by means of rigid fixtures. The diameter of the hub and blades increases from the fl...
