Definitions

  • the present invention relates to a wheel disk assembly having a wheel disk and a plurality of blade devices fastened on the wheel disk and a plurality of sealing plates fixed in an annular slot on the wheel disk.
  • Wheel disk assemblies of the type referred to in the introduction are known in the prior art in a very wide variety of embodiments, wherein in a conventional embodiment a wheel disk has on the outer circumference a plurality of blade-root-locating slots which extend in the direction of the disk axis. Blade devices are arranged in these by their blade root. For the end-face covering of the blade-root-locating slots, sealing plates are inserted and for this purpose are generally mounted in annular slots. GB 905,582 A discloses a typical example of this.
  • the wheel disk has an encompassing, outwardly open, inner annular slot in which is axially fixed an end of the sealing plate which points toward the disk axis. On the opposite outer end of the sealing plate provision is made for an inwardly open outer annular slot.
  • the outer annular slot is formed by the blade devices which are adjacent to each other in the circumferential direction.
  • the blade devices are inserted into the blade-root-locating slots of the wheel disk, wherein the sealing plates are also inserted in succession between the two annular slots.
  • all the sealing plates have to be already mounted beforehand and be displaced in the annular slots via their overlapping regions by such a distance that the blade devices can be installed in the associated slots of the wheel disk.
  • the sealing plates are then pushed back again in the circumferential direction into their designated position and suitably secured there against a displacement in the circumferential direction.
  • the generic wheel disk assembly comprises a wheel disk, a plurality of blade devices and a plurality of sealing plates.
  • the wheel disk has in this case a blade-locating section which is arranged on the outer circumference. Fastened on this, in a detachable and circumferentially distributed manner, are the blade devices.
  • the wheel disk has an annular projection which is at an axial distance from the blade-locating section. An annular slot is arranged between the blade-locating section and the annular projection.
  • the sealing plates by an edge region pointing toward the disk axis, are mounted in the annular slot and fixed in the axial direction by means of the blade-locating section and the annular projection.
  • the disk axis obviously corresponds to the central rotational axis of the rotor disk.
  • the edge region of the sealing plates is adjacent to the end of the sealing plates which points toward the disk axis and extends radially vertically corresponding to its arrangement in the annular slot.
  • the annular slot is widened in the axial direction by at least one recess which defines a sealing-plate-mounting region.
  • the recess extends from the annular slot in the axial direction into the blade-locating section and/or into the annular projection.
  • the length of the recess in the circumferential direction is greater than the length of the sealing plates in the edge region.
  • the sealing plates can be threaded in a simple manner into the associated annular slots, even if all the blade devices are already mounted on the wheel disk, as a result of which the mounting is designed in a very flexible manner.
  • the sealing plates can be inserted by the edge region for example at an angle from above into the recess and the sealing plate can then be tilted in the direction of the wheel disk. After that, the sealing plate can be moved in the circumferential direction along the annular slot.
  • the individual sealing plates can be removed again in a simple manner in the reverse sequence.
  • annular slot is of segmented and/or discontinuous design provided that the discontinued regions are not required for attaching a sealing plate.
  • all the sealing plates are identically designed as identical parts, as a result of which the production and also the storage of the sealing plates are simplified.
  • the recess also extends in the radial direction pointing toward the disk axis. That is to say that the recess over a limited length enlarges the cross section of the annular slot in the axial direction and in the radial direction.
  • the annular projection on the side facing the annular slot, advantageously has a bevel in the region of the recess, wherein the bevel is designed so that the annular projection is flattened toward the annular slot.
  • Such a bevel also simplifies the insertion and removal of the sealing plates in the region of the recess.
  • the annular projection on the side facing the annular slot, has in the region of the recess an undercut region in the form of a cavity which is open toward the annular slot.
  • the annular slot is of undercut design and, as seen in cross section, has at least one retaining projection which projects axially in the direction of the sealing plate.
  • the retaining projection is correspondingly selectively located on the blade-locating section and/or on the annular projection and is arranged radially outside the annular slot.
  • the retaining projection has a retaining surface on the side pointing toward the annular slot, i.e. toward the disk axis. It is irrelevant in the first instance whether retaining projections are provided on one side or on both sides and whether one retaining surface or a plurality of retaining surfaces are provided on the retaining projection.
  • the embodiment with a retaining projection extending circumferentially along the annular slot, with a retaining surface arranged thereon, is both adequately and advantageously simple.
  • the sealing plates in the edge region have at least one axially projecting support projection which is provided with a support surface. Therefore, the edge region with the support projection acts as a thickening for the region of the sealing plate which lies radially outside the edge region.
  • the retaining surface of the retaining projection and the support surface of the support projection are arranged in such a way that the support surfaces of the sealing plates, during the designated operation of the wheel disk assembly, are supported against the retaining surface of the retaining projection under the influence of a centrifugal force. Thanks to this embodiment, the natural weight of the sealing plates under the influence of a centrifugal force is absorbed by the wheel disk, as a result of which the blade devices are relieved of load.
  • the filler piece By means of the filler piece, it is possible to prevent an inadvertent slipping out of the sealing plate from the annular slot or a partial deformation of the sealing plate in a position in which the sealing plate is arranged over a part of the length in the region of the recess. To this end, it is necessary that the filler piece butts against the sealing plate.
  • the filler piece has an axially extending contact surface pointing radially outward, against which an inner circumference of the sealing plate butts.
  • the sealing plate in the region of the recess can be supported on the filler piece and, especially in the case of a recess which extends radially into the wheel disk, is not displaced toward the disk axis with the disk assembly stationary for example.
  • the filler piece is advantageously designed in such a way that a bevel provided on the annular projection is filled out.
  • the filler piece with provision of a cavity which opens toward the recess, projects into this cavity.
  • the radial fixing of the filler piece can be achieved.
  • the blade devices have in each case an annular slot segment which extends in sections around the disk axis and is open radially toward the disk axis.
  • the sealing plates are accommodated on their outer circumference in the annular slot segments and in this case are fixed in the axial direction.
  • Essential instead is a securing of the position of the sealing plate on the outer circumference in the direction of the disk axis.
  • the sealing plates advantageously have in each case a circumferential displacement lock which holds the corresponding sealing plate in the designated position during the designated use of the wheel disk assembly, that is to say prevents a displacement in the circumferential direction.
  • the sealing plates have a hole and the wheel disk has associated openings, wherein connecting elements which extend through the holes engage in the associated openings and in the process are advantageously fastened on the sealing plates. Thanks to the fixing of the connecting elements on the sealing plates, an unnecessary weakening of the wheel disk as a result of notch effect or the like is prevented.
  • the opening is advantageously designed in the form of a radially extending elongated hole.
  • the sealing plates can move radially outward under the influence of a centrifugal force during the designated use of the wheel disk assembly.
  • a multiplicity of edges and corners of the first annular slot and/or of the support protrusions and/or of the filler piece are provided with radii. As a result of such radii, a weakening of the corresponding component as a result of notch effect is avoided.
  • the present invention furthermore creates a method for installing a wheel disk assembly according to the invention, in which method all the blade devices are fastened on the wheel disk in a first step, and the sealing plates are mounted in a further step.
  • FIG. 1 shows a perspective view of a wheel disk assembly
  • FIG. 2 shows a perspective view of the wheel disk in the region of the recess
  • FIG. 3 shows a cross section through the wheel disk in the region of the recess
  • FIG. 4 shows a view similar to FIG. 2 with sealing plate inserted
  • FIG. 5 shows an enlarged perspective sectional view through the recess with sealing plate and inserted filler piece
  • FIG. 6 shows a cross section for the embodiment from FIG. 5 ;
  • FIG. 7 shows a side view of the filler piece for FIG. 5 ;
  • FIG. 8 shows a perspective view for FIG. 5 ;
  • FIG. 9 shows a perspective sectional view similar to FIG. 5 with an alternative design of the recess and of the filler piece.
  • FIGS. 1 to 8 show a wheel disk assembly 1 and its components according to a first embodiment of the present invention.
  • the wheel disk assembly 1 comprises a wheel disk 2 , a plurality of blade-devices 3 which are fastened along the outer circumference on a blade-locating section 24 of the wheel disk 2 in associated axially extending blade-root-locating slots 4 , and a plurality of sealing plates 5 which are retained between the wheel disk 2 and the blade devices 3 in radially spaced-apart annular slot and annular slot segments 6 , 7 .
  • the annular slot 6 is in this case provided in the wheel disk 2 and is delimited axially outward by means of a continuous annular projection 8 .
  • Formed opposite thereto in each case in the blade devices 3 is an annular slot segment 7 .
  • the annular slot 6 which is provided in the wheel disk 2 is of undercut design and, as seen in cross section, has an axially projecting retaining projection 9 which projection 9 is provided with a retaining surface 10 .
  • the sealing plates 5 in an edge region on the inside diameter, as seen in cross section, have an axially projecting support projection 11 which is designed to correspond to the retaining projection 9 and which projection 11 is provided with a support surface 12 .
  • two recesses 13 (of which recesses 13 only one recess 13 is shown in the figures), which are diametrically opposite each other and of identical design and in each case define a sealing-plate-locating region, are arranged on the annular slot 6 .
  • the length of the recess 13 in the circumferential direction is greater than the width of the sealing plates in the edge region which is accommodated in the annular slot 6 .
  • the recess 13 extends in the axial direction and widens the annular slot 6 .
  • the annular projection 8 on the side facing the first annular slot 6 in the region of the recess 13 , has a bevel 14 which bevel 14 is designed in such a way that the annular projection 8 is flattened toward the annular slot 6 .
  • the wheel disk assembly 1 also comprises a filler piece 15 which filler piece 15 is designed in such a way that it fills out the region which is widened in relation to the annular slot 6 by the recess 13 as well as the region of the bevel 14 .
  • the filler piece 15 has a projection 16 which axially points away from the annular projection 8 , extending beneath a sealing plate, and therefore defines an axially extending contact surface which serves for the location of an inner circumferential edge of at least one sealing plate 5 .
  • the recess 13 which also extends radially into the wheel disk 2 breaks up the base of the annular slot 6 which is otherwise provided in an encompassing manner for the seating for the sealing plates 5 . By means of the axial contact surface, a basically flush seating for the sealing plates 5 in the region of the recess 13 is created.
  • the sealing plates 5 are designed identically in each case and comprise a hole 17 in each case through which hole 17 extends a connecting element 18 of basically pin-like design in the designated installed state of the wheel disk assembly 1 , which connecting element 18 is fastened on the associated sealing plate 5 and engages in an opening 19 , in the form of a radially extending elongated hole, which is formed on the wheel disk 2 .
  • each sealing plate 5 is inserted by its edge region from above into the recess 13 and then tilted in the direction of the wheel disk 2 .
  • the sealing plate 5 can be moved upward, i.e. radially outward, then inserted by its outer circumferential edge into the annular slot segments 7 and then moved in a guided manner in the circumferential direction between the annular slot 6 and the annular slot segments 7 .
  • the individual sealing plates 5 are first of all pushed one on top of the other in the circumferential direction into overlapping regions so that after the mounting of the last sealing plate 5 the sealing-plate-mounting region which is defined by the recess 13 remains free.
  • the filler piece 15 is then inserted into the recess 13 .
  • the sealing plates 5 which are arranged adjacently to the recess 13 , are to be pushed in each case in the circumferential direction one onto the other so that in each case they lie half on the projection 16 of the filler piece 15 .
  • the filler piece 15 is secured against an inadvertent detachment by means of the overlying sealing plates 5 .
  • the connecting elements 19 are pushed through the holes 17 of sealing plates 5 so that the connecting elements 19 engage with the associated openings 18 which are positioned in each case in alignment with the holes 17 .
  • the connecting elements 19 are then fastened, for example by peening, to the sealing plates 5 . Now the sealing plates 5 are secured against an inadvertent displacement in the circumferential direction.
  • a centrifugal force acts upon the sealing plates 5 , which leads to the sealing plates 5 moving radially outward, wherein the connecting elements 19 are guided inside the associated openings 18 .
  • the radially outward movement of the sealing plates 5 is limited by the support projections 11 , which are formed on the sealing plates 5 , as soon as the support surfaces 12 of the support projections 11 come to butt against the retaining surfaces 10 of the retaining projections 9 of the wheel disk 2 . In this state, the wheel disk 2 then absorbs the forces which are created by the natural weight of the sealing plates 5 .
  • FIG. 9 shows an alternative embodiment of a recess 20 and of a filler piece 21 which is inserted into the recess 20 .
  • the recess 20 differs from the depicted recess 13 to the effect that the annular projection, on the side facing the annular slot 6 in the region of the recess 20 , has an undercut region with a cavity 22 which is open toward the recess 20 .
  • the filler piece 21 differs from the filler piece 15 to the effect that this also fills out the undercut region, i.e. the cavity 22 , and that in contrast to the filler piece 15 there is no provision for a projection 16 pointing away from the annular projection upon which rest the sealing plates 5 .
  • the embodiment shown in FIG. 9 corresponds to the previously described wheel disk assembly 1 , which is why the same component parts or components are identified by the same designations.
