Definitions

  • the invention relates to a distributor for an exhaust gas turbine according to the preamble of claim 1.
  • contour sleeve and bearing ring guide vanes are then provided radially outwardly to the blades, which are rotatably mounted in the bearing ring and can be adjusted by a mounted in the bearing housing adjusting mechanism.
  • the contour sleeve and bearing ring are screwed together by screws and are held by spacer ribs at a distance.
  • a flexible mounting ring holds and centers the bearing ring in the housing.
  • the mounting ring has a z-shaped cross-sectional profile, wherein a radially outwardly directed outer flange in the parting line between the Bearing housing and the spiral housing engages and is held simultaneously with the housing screws, while an inner, radially directed flange engages over the bearing ring on the outer circumference and is bolted to the bearing ring.
  • Between the inner and outer flange of the mounting ring has a relatively thin cylindrical portion through which the contour sleeve is held flexible with the diffuser so that it is in conjunction with the radial seal at the outlet of the exhaust gas turbine capable of thermally expanding, without the Clamp adjustment of the vanes.
  • the type of storage of the adjustment is complex in the production and installation.
  • the mounting ring has different wall thicknesses, so that its production is costly.
  • stator vane for a turbocharger in which a vane carrier plate, vanes, levers and an adjusting ring can be manufactured, transported and installed as a module, the components being captive after connecting vane axes and vane levers are connected to the vane support plate.
  • the invention is based on the object to store a collar for adjustable guide vanes of a gas turbine turbocharger in a simple manner and cost. It is achieved according to the invention by the features of claim 1. Further advantageous embodiments will be apparent from the dependent claims.
  • the annular support member is produced as a component with a constant wall thickness without cutting and / or machined.
  • it can be produced inexpensively with little effort, eg as Sheet metal part. It is also very easy.
  • its thermal expansions and deformations can be easily predetermined due to its simple configuration.
  • the bearing ring is captively connected via a rivet with the spacer element, with the contour sleeve and the support member and preferably forms with the guide vanes, which are adjustably mounted between the bearing ring and the contour sleeve, a mounting unit.
  • This is held in the housing of the exhaust gas turbine and centered by an outer, radially directed flange of the support member between a bearing housing and a volute casing of the exhaust gas turbine is clamped.
  • the spacer elements are sealing bolts on which rivet heads are formed on the front side. With these the spacer bolts are fastened on the one hand to the contour sleeve and on the other hand to the bearing ring. But it is also possible to connect the bearing ring, the contour sleeve and the support member, regardless of the spacer element with each other via a rivet connection, a screw connection, a welded connection or a press connection captive, so that they form a mounting unit.
  • the spacer can be made arbitrary in this case and e.g. be formed by a spacer rib on the contour sleeve and / or the bearing ring.
  • the support member is connected on the side facing away from the exhaust gas with the bearing ring, so that the inner flange is not directly exposed to the hot exhaust gases and the support member can be made of a low-cost material.
  • a retaining plate can be attached to the bearing ring, with molded brackets forms a receiving space for a collar for the vanes towards the support element.
  • Both the retaining ring and the adjusting ring as well as further parts of a control mechanism for the guide vanes can be added to the mounting unit by being captively connected to the bearing ring.
  • the compensation ring is arranged between the retaining plate and the support element and preferably fastened with the same fastening means as for this on the bearing ring.
  • the support member In order to reduce the thermal stresses in the suspension of the support member, it may also be appropriate to connect the support member on the exhaust side facing the bearing ring.
  • An exhaust gas turbine 10 of an exhaust gas turbocharger has a bearing housing 27, in which a shaft 14 of an impeller 13 is rotatably mounted about an axis of rotation 16. Via the shaft 14, the impeller 13 of the exhaust gas turbine 10 drives the impeller, not shown, of a compressor of the turbocharger.
  • the impeller 13 has blades 15, which exhaust gas via a radially outer guide 17 in the flow direction 35 is supplied.
  • the exhaust gas is passed through a turbine outlet 36 in an unillustrated exhaust system of an internal combustion engine.
  • the diffuser 17 essentially comprises a contoured sleeve 18 which forms a lateral boundary of the blades 15 with clearance and is held at a distance by spacer elements 20 in the form of spacer bolts to a bearing ring 22.
  • the spacer bolts 20 have rivet heads 21 on the front side, through which the contour sleeve 18 and the bearing ring 22 are pressed against stops of the spacer elements 20.
  • adjustable guide vanes 19 are rotatably mounted. They are adjusted by an adjusting mechanism 28 via a collar 39, lever 41 and the guide vanes 19 associated control shafts 29 in dependence on operating parameters.
  • the bearing ring 22 and the captive associated with him to a mounting unit components, in particular the contour sleeve 18, the vanes 19, the spacer elements 20, the bearing ring 22 and parts of the Stellmechnismus 28 are in the housing 11, 27 of the exhaust turbine 10 by an annular flexible support member 23 held and centered.
  • the support member 23 has a substantially z-shaped cross section with an outer radial flange 24 and an inner radial flange 25.
  • the support member 23 has a constant wall thickness and is suitably made of sheet metal. While the inner flange 25 is fixed to the bearing ring 22, the outer flange 24 is clamped between a mounting flange 30 of the bearing housing 27 and a mounting flange 31 of a spiral housing 11 by the two mounting flanges 30, 31 are held together by a clamping ring 32 in cross-section V-shaped ,
  • the spiral housing 11 has a spiral channel 12, the flow cross-section of which tapers from a tangential inlet, not shown, in a known manner over the circumference of the spiral housing 11.
  • the contour sleeve 18 is limited axially slidably inserted with its axially extending part and sealed at the outer periphery by a radial sealing ring 34 which is embedded in a groove 33.
  • the diffuser 17 can adjust to different thermal expansions during operation of the exhaust gas turbine 10, without causing tension of adjacent components, in particular the adjusting mechanism 28.
  • the spacer element 20 can simultaneously serve in the form of a spacer bolt, which has rivet heads 21 on the front side.
  • a retaining plate 37 can be attached to the bearing ring 22 by the spacer element 20.
  • the retaining plate 37 forms with its integrally formed brackets 38 to the support member 23 through an installation space for the adjusting ring 39th
  • a compensation ring 40 is provided between the retaining ring 37 and the support member 23. Since it behaves under the operating conditions similar to the retaining ring 37, its distance from the retaining ring 37 and its brackets 38 is constant, so that the set game is maintained during operation and thermal expansions and deformations do not affect the function of the actuating mechanism detrimental.
