- FIG. 4 shows a cross section through the guide blade ring of FIG. 3 in a cutting direction analogous to the cutting direction AA of FIG. 1;
- FIG. 4 shows a cross section through the guide blade ring of FIG. 3 in a cutting direction analogous to the cutting direction AA of FIG. 1;
- FIG. 5 shows a guide vane of the guide device according to the invention in a perspective view
- Fig. 6 the vane of Figure 5 in side view.
- FIG. 8 shows a cross section through the arrangement of FIG. 7 along the cutting direction B-B in FIG. 7.
- 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.
- 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 ,
- each vane 1 1 is arcuate, in particular circular arc, formed and introduced into a radially outer end thereof.
- the groove 13 of the vane ring 10 is arcuate, in particular circular arc, formed.
- 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.
- the groove 14 of the vanes 11 are aligned with the groove 13 of the vane ring 10.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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).
- 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. As already stated, one or more such screws 19 can be distributed over the circumference of the guide device 10 be arranged.
- the fastening of the guide blade ring to the guide blade carrier as well as the attachment of the retaining ring to the guide blade ring can be effected by a feather key or disc held by at least one screw in the guide blade carrier, which covers the three assemblies together.
- the production or assembly of a guide device according to the invention can be effected in that the groove 13 and in the guide vanes 1 1, the groove 14 before mounting the guide vanes 11 on the guide vane ring 10 and therefore separated from each other are introduced into the guide vane ring 1.
- the introduction of the groove 13 in the guide vane ring 10 is preferably carried out by turning or milling and the introduction of the groove 14 in the guide vanes 11 is preferably carried out by milling or bumping.
- the guide vanes 1 1 can be attached via the recesses 12 on the vane ring 10, to then, when the grooves 14 of the vanes 11 are aligned with the groove 13 of the vane ring i 0, the retaining ring 15 in the axial direction in the groove 13, 14 introduce ,
- the fabrication or assembly of the guide device according to the invention can also take place such that no-key guide vanes 1 1 are introduced into a groove-less guide vane ring 10 via the recesses 12, and then by turning or milling the grooves 13, 14 together into the guide vane ring 10 and the guide vanes 11 are introduced.
- the guide device according to the invention is characterized by a relatively low production cost and installation effort. Furthermore, it is relatively easy to replace guide vanes on the guide device according to the invention.
