Fig. 1 zeigt einen Ausschnitt aus einer erfindungsgemäßen Leitvorrichtung einer Strömungsmaschine im Bereich eines Leitschaufelrings 10 sowie mehrerer am Leitschaufelring 10 befestigter Leitschaufeln 11. Fig. 3 und 4 zeigen den Leitschaufelring 10 jeweils in Alleindarstellung, Fig. 5 und 6 zeigen eine Leitschaufel 11 ebenfalls jeweils in Alleindarstellung.Fig. 1 shows a section of a guide device according to the invention of a turbomachine in the region of a guide vane ring 10 and a plurality of guide vanes attached to the guide ring 10. Fig. 3 and 4 show the guide vane ring 10 in a solo view, Fig. 5 and 6 show a guide vane 11 also respectively in solo representation.
Der Leitschaufelring 10 ist vorzugsweise geteilt ausgeführt und aus zwei Hälften zusammengesetzt. Gemäß Fig. 1 sind die Leitschaufeln 11 am Leitschaufelring 10 in Umfangsrichtung desselben gesehen voneinander beabstandet befestigt, wobei zur Montage der Leitschaufeln 11 am Leitschaufelring 10 die Leitschaufeln in Aus- nehmungen 12 (siehe Fig. 3) des Leitschaufelrings 10 einführbar sind. Die Ausnehmungen 12 des Leitschaufelrings 10 erstrecken sich in Radialrichtung, so dass zur Montage der Leitscha'ufeln 11 am Leitschaufelring 10 die Leitschaufeln 1 1 von radial außen nach radial innen oder umgekehrt von radial innen nach radial außen in die Ausnehmungen 12 des Leitschaufelrings 10 eingeführt werden.The vane ring 10 is preferably made split and composed of two halves. According to FIG. 1, the guide vanes 11 are fastened to the guide blade ring 10 in the circumferential direction when viewed from one another. The guide vanes can be inserted into recesses 12 (see FIG. 3) of the guide ring 10 for mounting the guide vanes 11 on the guide blade ring 10. The recesses 12 of the vane ring 10 extend in the radial direction, so that for the Leitscha'ufeln 11 on the vane ring 10, the vanes 1 1 are introduced from radially outside to radially inside or vice versa from radially inside to radially outside into the recesses 12 of the vane ring 10 ,
Zur radialen Fixierung der Leitschaufeln 11 am Leitschaufelring 10 ist an einer Seite des Leitschaufelrings 10 eine in Umfangsrichtung desselben gesehen umlaufende Nut 13 in denselben eingebracht. Ebenso ist in jede Leitschaufel 1 1 an einer Seite derselben jeweils eine Nut 14 eingebracht. Die Nut 14 einer jeden Leitschaufel 1 1 ist bogenförmig, insbesondere kreisbogenförmig, ausgebildet und in ein radial außenliegendes Ende derselben eingebracht. Ebenso ist die Nut 13 des Leitschaufelrings 10 bogenförmig, insbesondere kreisbogenförmig, ausgebildet.For radial fixation of the guide vanes 11 on the guide vane ring 10, a circumferential groove 13 in the same circumferential groove is introduced on one side of the guide vane ring 10 in the same. Likewise, in each vane 1 1 on one side of the same each a groove 14 is introduced. The groove 14 of each vane 1 1 is arcuate, in particular circular arc, formed and introduced into a radially outer end thereof. Likewise, the groove 13 of the vane ring 10 is arcuate, in particular circular arc, formed.
Eine radial innenliegende Begrenzungsfläche und eine radial außenliegende Begrenzungsfläche der Nute 13, 14 von Leitschaufelring 10 und Leitschaufeln 1 1 weisen vorzugsweise einen Abstand zwischen 3 mm und 9 mm, insbesondere zwischen 4 mm und 8 mm, auf. Die radial innenliegende Begrenzungsfläche und die radial außenliegende Begrenzungsfläche der Nute 13, 14 sind entweder eben oder als Ausschnitte eine zylindrischen oder kegeligen oder toroidalen Fläche ausgestaltet.A radially inner boundary surface and a radially outer boundary surface of the groove 13, 14 of the guide blade ring 10 and guide vanes 1 1 preferably have a distance between 3 mm and 9 mm, in particular between 4 mm and 8 mm. The radially inner boundary surface and the radially outer boundary surface of the groove 13, 14 are either flat or designed as cutouts a cylindrical or conical or toroidal surface.
In montiertem Zustand der Leitschaufeln 11 am Leitschaufelring 10 fluchten die Nute 14 der Leitschaufeln 11 mit der Nut 13 des Leitschaufelrings 10. Zur radialen Fixierung der Leitschaufeln 1 1 am Leitschaufelring 10 dient ein Haltering 15, der, wie am besten Fig. 2 entnommen werden kann, in die Nut 13 des Leitschaufelrings 10 sowie in die Nute 14 der Leitschaufeln 11 eingreift. Über den Haltering 15 sind demnach die Leitschaufeln 11 in ihrer Radialposition am Leitschaufelring 10 fixierbar.In the assembled state of the vanes 11 on the vane ring 10, the groove 14 of the vanes 11 are aligned with the groove 13 of the vane ring 10. For radial fixation of the vanes 1 1 on the vane ring 10 is a retaining ring 15, which, as best Fig. 2 can be removed , engages in the groove 13 of the guide vane ring 10 and in the groove 14 of the vanes 11. Accordingly, the guide vanes 11 can be fixed in their radial position on the guide vane ring 10 via the retaining ring 15.
Die radiale Erstreckung des Halterings 15 ist an den Abstand zwischen der radial innenliegenden Begrenzungsfläche und der radial außenliegenden Begrenzungsfläche der Nute 13, 14 angepasst. Ebenso ist die Kontur von radialen Begren- zungsflächen des Halterings 15 an die Kontur der radial innenliegenden Begrenzungsfläche und der radial außenliegenden Begrenzungsfläche der Nute 13, 14 angepasst, sodass sich die radialen Begrenzungsflächen des Halterings 15 möglichst spielarm und vollflächig an die radialen Begrenzungsflächen der Nute 13, 14 anschmiegen. Wie ebenfalls am besten Fig. 2 entnommen werden kann, greifen die Leitschaufeln 11 mit radial innenliegenden Enden derselben zugeordneten Vorsprüngen 16 in Ausnehmungen eines Innendeckbands 17 der Leitvorrichtung ein, wobei jedoch ein derartiges Innendeckband 17 rein optional ist. Die erfindungsgemäße Leitvorrichtung kann auch ohne Innendeckband ausgeführt sein, wobei dann den Leitschaufeln an den radial innenliegenden Enden derselben keine Vorsprünge zugeordnet sind.The radial extension of the retaining ring 15 is adapted to the distance between the radially inner boundary surface and the radially outer boundary surface of the groove 13, 14. Likewise, the contour of radial boundary surfaces of the retaining ring 15 is adapted to the contour of the radially inner boundary surface and the radially outer boundary surface of the groove 13, 14, so that the radial boundary surfaces of the retaining ring 15 as possible with low backlash and full surface of the radial boundary surfaces of the groove 13th , 14 clinging. As can also best be seen from FIG. 2, the guide vanes 11 engage with radially inwardly disposed ends of the same associated projections 16 in recesses of an inner cover strip 17 of the guide device, but such an inner cover strip 17 is purely optional. The guide device according to the invention can also be designed without inner cover tape, wherein then the guide vanes at the radially inner ends of the same are assigned no projections.
Der Leitschaufelring 10 ist zusammen mit den am Leitschaufelring 10 fixierten Leitschaufeln 11 gemäß Fig. 7 und 8 an einem Leitschaufelträger 18 befestigbar, und zwar gemäß Fig. 7 und 8 über mindestens eine Schraube 19. Gemäß Fig. 8 greift die Schraube 19 mit einem Schraubenschaft 20 ausschließlich in den Leitschaufelträger 18 ein, die Schraube 19 überdeckt jedoch mit ihrem Schraubenkopf 21 abschnittsweise sowohl den Schaufelträger 18 als auch den Schaufelring 10 sowie den Haltering 15 (siehe Fig. 7).The guide blade ring 10 can be fastened together with the stator blades 11 fixed to the guide blade ring 10 according to FIGS. 7 and 8 to a guide blade carrier 18, as shown in FIGS. 7 and 8 via at least one screw 19. According to FIG. 8, the screw 19 engages with a screw shaft 20 exclusively in the guide vane carrier 18, but the screw 19 covers with its screw head 21 in sections both the blade carrier 18 and the blade ring 10 and the retaining ring 15 (see Fig. 7).
Über die Schraube 19 ist demnach einerseits der Leitschaufelring 10 am Leitschaufelträger 18 zirkulär befestigbar, weiterhin dient die Schraube 19 der zirkulären Fixierung des Halterings 15 im Leitschaufelring 10. Wie bereits ausgeführt, können eine oder auch mehrere derartige Schrauben 19 über den Umfang der Leitvorrichtung 10 verteilt angeordnet sein.Accordingly, on the one hand, the guide vane ring 10 can be fastened to the guide vane support 18 in circular fashion. Furthermore, the screw 19 serves for the circular fixing of the retaining ring 15 in the vane ring 10.
