Definitions

  • the present invention relates to a wheel disk arrangement with a wheel disk, a plurality of vane devices which are fastened along an outer circumference of the wheel disk, a number of sealing plates which are received between the wheel disk and the vane devices so as to be displaceable in the circumferential direction, and securing devices which are designed in such a way that they enclose the sealing plates Secure against displacement in the circumferential direction, bolts being provided as securing devices, which are held releasably in bores arranged in the wheel disk and engage in recesses formed on the surfaces of the sealing plates facing the wheel disk.
  • Wheel disk assemblies of the type mentioned are known in the prior art. They form components of rotors such as gas turbines or the like. Normally, several sealing plates are accommodated between the wheel disk and the blade devices so as to be displaceable in the circumferential direction. For example, the sealing plates can be inserted into annular grooves which are arranged radially spaced from one another and which are formed on the wheel disk on the one hand and on the blade devices on the other. In order to ensure proper functioning of the sealing plates, it is necessary to secure the individual sealing plates against displacement in the circumferential direction, for which purpose appropriate safety devices are used.
  • Such a securing device can be formed, for example, by a screw extending through a through hole provided in the sealing plate and a threaded hole provided on the wheel disc, into which the screw is screwed in the properly installed state.
  • a securing device designed in this way is, however, that the notch effect associated with the threaded hole provided in the wheel disc has a negative effect on the strength affect the wheel disc and cause problems accordingly.
  • screws can often no longer be loosened, which entails laborious drilling out of the screw connection, as a result of which the expensive wheel disc is damaged.
  • the U.S. 3,070,351 a retaining ring for rotor blades of a compressor that are seated in axial grooves.
  • Clamping sleeves are provided to fasten the retaining ring to the paddle wheel.
  • the adapter sleeves sit in aligned bores that are provided on the one hand in the paddle wheel and on the other hand in the locking ring. The seat of the clamping sleeves is no longer secured, so that the clamping sleeves can be lost.
  • the present invention creates a wheel disk arrangement of the type mentioned at the outset, wherein the relevant bolts can resiliently be plunged further into the bore for manual release of the engagement of the respective bolt from the associated recess. Due to the fact that the bolts of the securing devices according to the invention, in contrast to the prior art described at the beginning, are not screwed to the wheel disc but are only inserted into bores of the wheel disk and can be resiliently plunged further into the bore to release the engagement, a self-locking bolt can thus be provided that does not have to be secured against loss by another component.
  • the sealing plate in which the bolt engages therefore also serves as a means against loss of the bolt.
  • a simple and reliable wheel disk arrangement is thus specified, which also allows particularly simple and quick assembly, such as disassembly of the sealing plates and bolts.
  • the at least one bolt has at its end region facing the wheel disk at least one radially outwardly projecting projection as a contact for an associated sealing plate. In this way, a secure and correct positioning of the sealing plates is ensured while maintaining a defined distance between the wheel disc and the sealing plates.
  • the bolts are designed in such a way that, in their final assembly position, they press resiliently against the surfaces of the sealing plates facing the wheel disk in a supporting manner on the bottom of the hole. This ensures that the bolt is seated in the recess of the sealing plate without play and therefore with little wear.
  • the bore can preferably be designed without threads, so that the strength of the wheel disc is not reduced by the notch effect of threads.
  • the bore has a substantially hemispherical bore bottom. Accordingly, there is a transition radius between the hole and the bottom of the hole, which also prevents unnecessary weakening of the wheel disc.
  • the bolts preferably have at least one, preferably two spring legs, which engage in the associated bore. Thanks to this one-piece structure, the bolts can be easily and repeatedly assembled and disassembled. According to this preferred embodiment, a separate spring is not required, which simplifies assembly.
  • the spring legs are advantageously arranged opposite one another, whereby uniformly acting clamping forces are achieved.
  • the at least one projection is advantageously designed in the shape of a ring, which is particularly advantageous with regard to the manufacture of the bolt.
  • the recesses formed on the sealing plates are designed as through holes. On the one hand, this is advantageous from a manufacturing point of view. On the other hand, the bolts can be inserted more easily into the associated recesses, since they are visible from the outside through the through holes.
  • the recesses formed on the sealing plates are advantageously designed as radially extending elongated holes in order to be able to compensate for thermal expansions during the intended use of the wheel disk arrangement.
  • the Figures 1 to 5 show a wheel disk arrangement 1 according to an embodiment of the present invention or components thereof.
  • the wheel disk arrangement 1 comprises a wheel disk 2, a plurality of vane devices 3 which are fastened along an outer circumference of the wheel disk 2, and a number of sealing plates 4 which extend between the wheel disk 2 and the vane devices 3 and are accommodated so as to be displaceable in the circumferential direction U. More precisely, the sealing plates 4 are inserted into annular grooves which are arranged at a distance from one another in the radial direction R, the annular grooves being formed on the wheel disk 2 on the one hand and on the blade devices 3 on the other.
  • the wheel disk arrangement 1 comprises several safety devices 5, in this case one safety device 5 per sealing plate 4.
  • Each safety device 5 has a bolt 6 which is fastened to the wheel disk 2 and which is inserted into a recess 7 engages, which is formed on the surface of each sealing plate 4 facing the wheel disk 2.
  • the bolts 6 are held in a releasable clamping manner in thread-free bores 8 of the wheel disk 2, each bore 8 having a substantially hemispherical bore bottom.
  • the bolts 6 At their end region facing the wheel disk 2, the bolts 6 have two oppositely arranged spring legs 9 which, in the properly installed state, rest against the wall of the bore 8 while exerting a clamping force, as shown in FIG Figure 2 is shown.
  • the bolts 8 At their end area facing away from the wheel disk 2, the bolts 8 have a radially outwardly projecting projection 10 which in the present case is annular and serves as a contact for an associated sealing plate 4. At the same time, the projection 10 acts as a spacer and defines a predetermined distance between the wheel disc 2 and the corresponding one Sealing plate 4.
  • the recesses 7 formed on the sealing plates 4 are provided as through holes, more precisely as continuous and radially extending elongated holes, so that the bolts 6 remain free of movement in the radial direction R, in particular in the radial outward direction.
  • the wheel disk arrangement 1 is characterized in particular by the fact that the bolts 6, thanks to the spring legs 9, can be easily and repeatedly assembled and disassembled. While during assembly the bolt 6 is first immersed so deeply into the bore that a sealing plate can then be moved past its end area, the bolt 6 must also be immersed in the bore 8 for dismantling in order to engage the bolt 6 with the recess 7 to solve and thus enable a displacement of the sealing plate in the circumferential direction.
  • the spring action of the bolt 6 is directed so that the bolt at least partially moves out of its bore as soon as it is released.
  • the bore 8 is designed to be thread-free, so that the strength of the wheel disc 2 is not unnecessarily impaired by the notch effect.
  • the essentially hemispherical hole bottom is also beneficial to the strength. Thanks to the projection 10, a defined position of the sealing plates 4 is guaranteed in the properly installed state.
  • the design of the recesses 7 as radially extending and continuous elongated holes, which leave the bolt 6 a free movement in the radial direction, enables a compensation of thermal expansions of the sealing plates 4 during the intended operation of the wheel disk arrangement 1.
