Definitions
- Turbine housing with a low-stress connecting flange and exhaust gas turbine with such a turbine housing
- the invention relates to a turbine housing with a low-stress connecting flange and an exhaust gas turbine with such a turbine housing.
- the exhaust gas turbine can be, for example, a turbocharger turbine for a turbocharger or a utility turbine.
- a one-piece exhaust system of a gas turbine is known from US 2015/0143814 A1.
- This exhaust system has a turbine outlet housing and a turbine exhaust manifold, the turbine outlet housing being connected to the turbine exhaust manifold at outwardly directed interface flanges. This makes it possible, if necessary, to detach the turbine exhaust manifold by simply decoupling it from the turbine outlet housing and to replace it with a new component.
- a gas turbine is known from EP 3 103 972 A1, in which a high-pressure turbine housing is connected to a diffuser housing on outwardly directed flanges.
- a typical turbocharger has a turbine housing, a bearing housing and a compressor housing, the turbine housing being connected to the bearing housing and the bearing housing also being connected to the compressor housing.
- the connection between the turbine housing and the bearing housing must meet several requirements. These requirements include ensuring gas tightness, preventing twisting between the two housings due to external forces and ensuring that the two housings are held together even in the event of a burst.
- the connection between the turbine housing and the bearing housing must in particular be designed in such a way that it can cope with large temperature differences between the turbine housing and the bearing housing and high forces in the event of a burst.
- a reliable safety enclosure - called "containment" in English - is a very important and therefore structurally very demanding requirement for an exhaust gas turbine in such a burst.
- FIG. 1 shows a first sectional view to illustrate a turbine housing according to the prior art.
- This turbine housing has a connecting flange 2, via which the turbine housing 1 is connected to the bearing housing 14 of a turbocharger.
- This connection is implemented using connecting elements screwed into the housing connecting bores of the connecting flange, which press clamping lugs 16 onto the connecting flange 2 of the turbine housing 1 and onto the bearing housing 14 by means of nuts 17, whereby the bearing housing 14 is also pressed against the turbine housing.
- the mentioned housing connection bores are spaced from one another (that is to say spatially apart from one another) and are arranged in the circumferential direction along a circle.
- the clamping lugs are also arranged along a circle in the circumferential direction of the turbine housing.
- FIG. 2 shows a second sectional view to illustrate a turbine housing according to the prior art.
- This second sectional illustration illustrates the turbine housing at an interface at which a connecting element 15 is screwed into a housing connecting bore 3 of the connecting flange 2 of the turbine housing.
- a clamping lug 16 is pressed both onto the turbine housing 2 and onto the bearing housing 14, which is implemented using a nut 17 and a washer 18.
- the object of the invention is to provide a turbine housing and an exhaust gas turbine in which the disadvantages mentioned above with reference to a turbocharger are reduced.
- a turbine housing of this type has a connecting flange for connection on the bearing housing side to a bearing housing, in which housing connecting bores spaced apart from one another in the circumferential direction are provided, with material recesses in the connecting flange being provided between adjacent housing connecting bores radially inwardly towards a longitudinal center axis of the turbine housing.
- the turbine housing can also be in several parts.
- a heat shield or a nozzle ring can be arranged between the turbine housing and the bearing housing.
- drilling is to be interpreted functionally and not, due to manufacturing reasons, to mechanical processing using a drilling machine or milling machine.
- the spaced apart housing connecting bores in the connecting flange are arranged along at least one circle.
- the turbine housing has a clamping edge which is arranged adjacent to the housing connecting bores in the radial direction.
- annular recess is provided in the clamping edge, which has a recess base, the adjacent housing connection bores being made in the recess base and the material recesses provided between two adjacent housing connection bores being provided in the recess base.
- the clamping edge in the area between two adjacent housing connecting bores each has a clamping edge recess that widens the annular recess.
- the depth of the clamping edge recess corresponds to the sum of the depth of the annular recess and the depth of the material recesses provided in the annular recess.
- the turbine housing is constructed in several pieces.
- the clamping edge forms a separate part of the turbine housing.
- a heat shield or a nozzle ring forms a separate part of the turbine housing.
- the clamping edge is part of the heat shield or the nozzle ring.
- an exhaust gas turbine has a turbine housing with the features according to the invention.
- an exhaust gas turbine has a bearing housing connected to the turbine housing, the turbine housing being connected to the bearing housing by means of connecting elements.
- an exhaust gas turbine has clamping elements, each of which is formed by a connecting element or by several Connecting elements are pressed to the connecting flange of the turbine housing and to the bearing housing.
- the clamping elements of the exhaust gas turbine are pressed against the clamping edge.
- the connecting elements are screws or threaded pins.
- the advantages of the invention are in particular that the material recesses provided between the housing connecting bores enable the connecting flange area to be heated more quickly and more evenly during operation of the respective exhaust gas turbine. Due to these material cutouts, there is also a reduced rigidity of the turbine housing in the area of the connecting flange. As a result, lower thermal transient stresses occur when the exhaust gas turbine is in operation. This in turn leads to an extension of the service life of the turbine housing and thus also to an extension of the service life of the entire exhaust gas turbine.

- FIG. 9 shows a sectional illustration in the direction of the cutting line shown in FIG.
- FIG. 3 shows a sketch to illustrate a turbine housing according to the invention, only a partial area of this turbine housing being shown in FIG.

- connecting webs 19 extending inward in the radial direction 8 are provided, in which housing connecting bores 3 are made.

- a connection of the turbine housing to a bearing housing of a turbocharger takes place in the same way as was explained above in connection with FIG. 2 using connecting elements which are each introduced into a housing connecting bore 3 of the connecting flange 2, Furthermore, clamping elements arranged along a circle in the circumferential direction of the turbine housing, which in one embodiment are clamping lugs, are pressed onto both the turbine housing and the bearing housing, which is implemented using a nut and a washer.
- the material recesses 4 provided in contrast to the prior art bring about faster and more uniform heating of the connecting flange 2 of the turbine housing when the turbocharger is in operation. Furthermore, due to the material cutouts 4 made in the connecting flange 2, there is a reduced rigidity of the turbine housing in the area of the connecting flange 2. This in turn has the consequence that in the area of the connecting flange 2, reduced thermal transient stresses occur in comparison with the prior art. This reduction in thermal transient stresses in the area of the connecting flange extends the service life of the turbine housing and thus also the service life of the entire turbocharger.
- FIG. 4 shows a sectional illustration in the radial direction to illustrate an embodiment of the invention.
- the connection flange 2 of the turbine housing and the bearing housing 14 connected to the connection flange 2 and thus to the turbine housing 14 are shown.
