Definitions
- the invention relates to a fixing device for blading a Fluid machine, in which a number of blades along a fastening groove introduced and between at least two within the mounting groove An intermediate assembly gap is provided adjacent to the blades two insert elements designed as end halves, which in the Assembly gap can be used and one each to the width of the Intermediate assembly gap have adjusted width and a between them Include a gap into which a wedge element can be inserted that can be wedged in this way is that both end halves are non-positively by the wedge element inside the Fastening groove are fixed.
- Blades of the above type relate to guidance, but in particular Blades within turbomachines, such as the compressors or Turbine stage of a gas turbine plant.
- the explanations below preferably refer to blades running along a mounting groove that is provided within the rotor of a turbomachine and this along its Circumferential circumferences are fixed and depending on the respective Position the flow conditions in a suitable manner and opposite possible misalignments occurring during the operation of the Turbo machines but especially against complete detachment from the The fastening groove must be reliably secured. That in relation to the blades too Measures as described below can also be taken also on those in the fixed housing components of turbomachinery integrated guide vanes find application.
- Known security measures against self-releasing individual blades from the mounting groove generally refer to reducing the clearance between two adjacent blade feet within the fastening groove in the circumferential direction.
- FIG. 2a shows a cross section through a Fastening groove 1, which is incorporated within a rotor 2.
- the so-called rotor closure 4 is radial between the two blades 31, 32 in the mounting groove 1 inserted.
- the rotor end 4 consists, as in Figure 2b in Individual emerges from two so-called closing halves 41, 42 and a wedge element 43.
- the sides of the closing halves 41, 42 facing the fastening groove 1 are for a positive and positive engagement with the inner contour of the Fastening groove 1 designed accordingly.
- both end halves 41, 42 When inserted within the Fastening groove 1, both end halves 41, 42 include an intermediate gap 5, in which the wedge element 43 can be inserted radially.
- the End halves 41, 42 In the upper area, the End halves 41, 42 have a corresponding recess 6 (see Fig. 2b), the each resembles half a heart shape, in the retaining tab 44 of the wedge element 43 as shown in Figure 2a, be spread permanently to both end halves 41, 42 to press permanently against the inner contour of the fastening groove 1.
- a fixing device according to the preamble of Claim 1, see for example a generic fixing device under Reference to Figures 2a - 2c, designed such that the wedge element at least one connecting element to the side of a blade and at least one of the two blades adjacent to the wedge element one to the Connection element provides corresponding counter-contour, so that Wedge element and the blade an intimate positive connection with each other received.
- the idea underlying the invention is to create an intimate one Positive connection between the wedge element and at least one directly adjacent blade so that there are no relative displacements between the Blade and the wedge element and connected to the entire rotor tail can occur, whereby the risk potential described above be decisively restricted with regard to the detachment of the wedge element can.
- the wedge element is direct with both adjacent blades via respective positive connection elements connected.
- Figure 1a shows a plan view of a composite consisting of two within one Fastening groove (not shown) inserted blades 31, 32 and one rotor end located between the blades 31, 32 4.
- the rotor end 4 has a wedge element 43, which on its rotor blades 31, 32 facing sides each designed as a dovetail Has connecting element 45, each in one, within the blades 31, 32 incorporated counter contour 46 engages positively and non-positively.
- the counter contours are 46 clearly visible within the blades 31, 32.
- To assemble the rotor tail 4 designed according to the invention are first the End halves 41, 42 in the intermediate gap between the blades 31, 32 inserted radially into the mounting groove. Then that will Wedge element 43 designed according to the invention also radially both in the Intermediate gap between the two closing halves 41, 42 as well as within the opposite counter contours 46 of the blades 31, 32 radially introduced.
- the two adjacent blades 31, 32 by the Wedge element 43 mechanically connected to one another. Is the wedge element 43 completely sunk between the end halves 41, 42, so the retaining tabs 44 of the wedge element 43 in the heart-shaped recesses 6 with the help a suitable tool.
- connection profiles are also conceivable, for example Hammer profiles of all kinds as well as fir tree profiles.
- the Counter contour 46 within the blade root of the individual moving blades 31, 32 brought in.
- the counter contour 46 does not necessarily extend over the total depth of the blade root.
- Figure 1c is a side view of the rotor tail designed according to the invention 4 shown.
- Wedge element 43 which is designed according to the invention as a dovetail Connecting element 45, which according to the embodiment in Figure 1c extends the entire length of the blade root.
- the wedge element 43 has two retaining tabs 44 which fit into the corresponding one Engage recess 6 within the blades 41, 42.
