  • Wheel disc assemblies of the type mentioned are known in the prior art in a variety of configurations.
  • the blade devices are inserted into grooves of the wheel disc, wherein successively, the sealing plates are inserted into the two annular grooves.
  • all sealing plates must already be mounted and moved so far over their overlap areas in the annular grooves that the blade means can be installed in the associated grooves of the wheel disc. Subsequently, the sealing plates are pushed in the circumferential direction back to its intended position and secured there against displacement suitable.
  • the present invention provides a Radularnan extract of the aforementioned type, which is characterized in that at least one axially extending through the annular projection extending recess is provided whose minimum width in the circumferential direction is greater than the width of the sealing plates on the inner diameter, so in that a sealing plate can be inserted axially through the recess between the annular grooves and guided in the circumferential direction by these, and that at least one closure piece is provided, which is prepared for closing the recess and releasably attachable to the wheel disc, wherein the closure piece in the intended mounted state is held captive in the axial direction by a positive connection provided between the closure piece and at least one sealing plate.
  • the sealing plates can be threaded in a simple manner in the associated annular grooves, even if all blade devices are already mounted on the wheel disc, whereby the assembly is made very flexible. Also, the individual sealing plates can be removed easily in the service case through the recess without much effort. Thanks to the provided between the closure piece and at least one sealing plate positive locking additional securing elements for securing the closure piece in the assembled state are superfluous, whereby a very simple structure with few components is achieved.
  • the positive connection is realized by at least one radially projecting projection of the closure piece and at least one recess formed on the sealing plate, in which the projection engages in the intended mounted state.
  • the at least one recess is designed as a ring-segment-shaped groove extending in the circumferential direction and the at least one projection is designed as a ring-segment-shaped web extending in the circumferential direction, whereby a simple structure is achieved.
  • the first annular groove is formed undercut and has, viewed in cross-section, at least one axially projecting retaining projection, which is provided with a contact surface, and the sealing plates in the region of the inner diameter viewed in cross section in each case at least one axially projecting corresponding to the at least one retaining projection formed Supporting projection, which is provided with a bearing surface, wherein the contact surface of the at least one retaining projection, the support surface of the at least one support projection and the height of the sealing plates are formed such that the wings of the sealing plates during normal operation of the Radusionnan angel under the action of centrifugal against support the contact surface of the at least one retaining projection.
  • the sealing plates include in the region of the inner diameter in cross section considered two corresponding to the retaining projections formed axially opposing and mutually facing support projections, which are each provided with a support surface, wherein the contact surfaces and the support surfaces are formed such that support the support surfaces of the sealing plates during normal operation of the Radusionnanowski extract under the influence of centrifugal force against the contact surfaces of the retaining projections.
  • the contact surface of the at least one holding projection and the support surfaces of the sealing plates each extend both transversely to the radial direction and transversely to the axial direction.
  • the contact surfaces and the wings are each inclined.
  • the side surfaces of the sealing plates extend at least partially transversely to the axial direction and are formed such that the sealing plates overlap in the intended state with respect to the axial direction in the region of their side surfaces. In this way, a sealing effect is achieved between the side surfaces adjacent arranged sealing plates in the axial direction.
  • the side surfaces of the sealing plates are stepped, so that the sealing plates while maintaining a Overlap in the circumferential direction to each other by a predetermined amount can be moved.
  • the grading should be chosen such that the sealing plates in a state in which all the sealing plates of a Radularnanowski are mounted, can be pushed together so that between two adjacent sealing plates arranged a distance can be set, which is greater than the width of a single sealing plate.
  • Such a configuration may be advantageous depending on the type of mounting of the sealing sheets, as will become apparent from the embodiment described below with reference to the figures.
  • the at least one closure piece on opposite sides radially outwardly projecting Ver gleich Swissvorsprünge, which engage in the intended state in correspondingly formed pockets of the recess.
  • the closure piece can be secured in the circumferential direction of the wheel disc.
  • FIGS. 1 to 4 show a wheel disc assembly 1 according to an embodiment of the present invention or components thereof.
  • the wheel disc assembly 1 comprises a wheel disc 2, a plurality of blade means 3 which are fixed along the outer periphery of the wheel disc 2, and a plurality of sealing plates 4, which are held between the wheel disc 2 and the blade means 3 in two radially spaced annular grooves 5 and 6.
  • the first annular groove 5 is provided in the wheel disc 2 and is limited axially outwardly by an annular projection 7.
  • the second annular groove 6 is defined by a plurality of adjacently arranged annular groove segments which are respectively formed in the blade devices 3.
  • the wheel disc 2 comprises at least one axially extending through the annular projection 7 through recess 8, the minimum width in the circumferential direction is greater than the width of the sealing plates 4 at the inner diameter. Accordingly, the sealing plates 4 can be axially inserted through the recess 8 between the annular grooves 5 and 6 and moved in the circumferential direction of these.
  • the wheel disc assembly 1 also comprises a closure piece 9, which can be releasably secured to the wheel disc 2.
  • the provided on the wheel disc 2 first annular groove 5 is formed undercut and, viewed in cross section has two axially opposite and mutually facing retaining projections 10, which are each provided with a contact surface 11.
  • the sealing plates 4 include in the area of their Inner diameter in cross-section considered two corresponding to the holding projections 10 formed, axially opposite each other and facing away from each other support projections 12, which are each provided with a support surface 13.
  • the holding projections 10 and the supporting projections 12 each extend transversely to the radial direction R as well as transversely to the axial direction A and are presently arranged on the bisecting line, although other inclinations are possible.
  • the contact surfaces 11 of the retaining projections 10, the support surfaces 13 of the support projections 12 and the height of the sealing plates 4 are formed or selected such that the support surfaces 13 of the sealing plates 4 during normal operation of the Radepticnan extract 1 under the action of centrifugal force against the contact surfaces 11 of Support holding projections 10.
  • the side surfaces 14 of the sealing plates 4 extend at least partially transversely to the axial device A and are formed such that the sealing plates 4 overlap in their intended condition with respect to the axial direction A in the region of their side surfaces 14.
  • the side surfaces 14 of the sealing plates 4 are stepped, so that adjacent arranged and overlapping sealing plates 4 can be displaced in the radial direction while maintaining the overlap.
  • the degree of overlap is selected such that the sealing sheets 4 are mounted in a state in which all the sealing sheets 4 are mounted on the wheel disc assembly 1, as shown in FIG FIG. 1 is shown, can slide into one another such that between two adjacently arranged sealing plates 4, a distance can be set, which is greater than the maximum width of the sealing plates 4.
  • the recess 8 comprises pockets 15 arranged on both sides, which extend axially through the entire annular projection 7 and form undercuts in the radial direction.
  • the closure piece 9 comprises corresponding to the pockets 15 formed, radially outwardly projecting VerMAN Swissvorsprünge 16 which engage in the intended condition of the closure piece 9 in the pockets 15, whereby in the radial Direction a fuse of the closure piece 9 is achieved.
  • the closure piece 9 further comprises a receiving surface 17 which serves to receive at least one sealing plate 4. In the area of the receiving surface 17, the closure piece 9 has a web 18 extending in the radial direction, which engages in the intended state in correspondingly formed, provided on the inner diameter of the sealing plates 4 grooves 19 of the sealing plates 4.
  • the sealing plates 4 are moved in the circumferential direction in its intended position.
  • the grooves 19 of the sealing plates 4 are two adjacent sealing plates 4 each partially with the form of the receiving surface 17 of the closure piece 9 projecting web 18 is brought into engagement.
  • the sealing plates 4 are fixed by suitable means in their intended circumferential position.
  • a fixation for example, using bolts not shown in detail, which extend through provided in the sealing plates 4, extending in the radial direction elongated holes and fixed to the wheel disc 2.
  • the slots are used to allow movement of the sealing plates 4 during normal operation of the wheel disc assembly 1 in the radial direction.
  • other suitable fastening means can be used to fix the sealing plates 4 in their intended circumferential position.
  • a significant advantage of the wheel disc assembly 1 is that the sealing plates 4 can be easily and easily assembled and disassembled, even if the blade devices 3 are already or still fixed to the wheel disc 2. Further, the contact surfaces 11 of the retaining projections 10, the support surfaces 13 of the support projections 12 and the height of the sealing plates 4 are formed such that the support surfaces 13 of the sealing plates 4 during normal operation of the Radusionnan Aunt 1 under the action of centrifugal force against the contact surface 11 of the retaining projections 10 support. Thus, the weight of the sealing plates 4 is taken up by the wheel disc 2, resulting in that the connection areas between the wheel disc 2 and the blade means 3 must be less stable and thus can be produced more cheaply.
  • the closure piece 9 is due to the positive connection between the web 18 of the closure piece 9 and the grooves 19 of the sealing plates 4 secured in a simple manner without additional securing elements in its intended position, whereby a total of a simple structure is achieved.
  • said positive connection can also be achieved by means of a depression provided on the closure piece 9 and projections or webs projecting radially from the sealing plates 4.
  • FIG. 5 it should also be noted that it is basically sufficient, a single retaining projection 10 and a single Provide support projection 12, as in FIG. 5 is shown in the same or similar components with the same reference numerals as in the FIGS. 1 to 4 are provided. Otherwise, the in FIG. 5 shown arrangement of that arrangement, previously with reference to the FIGS. 2 to 4 has been described.
  • FIG. 6 shows a further alternative embodiment of the in the FIGS. 2 to 4 arrangement shown, which differs only to the effect that for axial securing of the closure piece 9 on sealing plates 4 radially inwardly projecting webs 20 are formed and on the closure piece 9 a correspondingly shaped groove 21 is provided, whereby a positive connection between the closure piece 9 and the sealing plates in intended condition is achieved.
  • the arrangements correspond to each other, which is why identical or similar components are provided with the same reference numerals.
