Definitions
- the invention relates to an apparatus and a method for Assembly of blades with essentially axial feet into the corresponding axial grooves of a rotor Fluid machine.
- Such devices and methods for the assembly of rotor blades with essentially axial feet in the corresponding axial grooves of a rotor of a turbomachine are known see e.g. the document US-A-1 720 729. They are used to assemble blades Row of blades needed, the blades of which, for example. with specifically molded cover bands, platforms or with shovel feet are formed with overlaps. To the last shovel Being able to axially mount a row of blades becomes a special blade needed. These special blades are in theirs Manufacturing very expensive and assembly requires special Effort, or is not always for technical reasons possible. Next is the use of special blades logistically very complex.
- the invention has for its object in a device for the assembly of blades and the associated procedure the assembly of rotor blades of the type mentioned to simplify with axial feet.
- this is achieved in that the assembly device from a radially outer headboard with at least one, essentially the axial root of the blade corresponding axial groove and a radially inner Foot part for mounting in a groove running around the rotor consists.
- the advantages of the invention include that blades with axial feet are inserted radially can be. This allows the blades without Consideration of an axial displacement can be designed. That means that bsw. Cover tapes, platforms or Bucket feet can have any shape.
- Rotary grooves are already present, for example. to record of heat accumulation segments in the case of gas turbine rotors. These circumferential grooves can then be used to mount the blades be used.
- blades 1 are blades 1, consisting of a blade root 1A and airfoil 1B, in axial grooves 11a of a rotor 10 used.
- a platform 3 arranged. At the contact surfaces of this Platforms are sealed using sealing strips 5, which are inserted in sealing grooves 4.
- FIG. 3 shows a one-piece assembly device 6, consisting of a foot part 7 and a head part 8.
- head part 8 is shaped according to the axial groove 11a Axial groove 11b arranged.
- A is now in the axial groove 11b Blade root 1A of a blade 1 inserted.
- each the sealing strips 5 are inserted before the blades 1 by means of the mounting device 6 along the circumferential groove 12a are pushed together.
- the sealing strips 5 not axially after the installation of the blades 1 are inserted into the sealing grooves 4 on the rotor 10 need, they can essentially be shaped arbitrarily his.
- the whole Blade row R is now, using the axial displacement due to the games between the Platforms 3, piece by piece in the axial grooves 11a of the Rotor pushed. If all blades 1 with their Blade feet 1A inserted in the axial grooves 11a of the rotor are, the mounting devices 6 can not shown filling opening of the circumferential groove 12a of the Rotor can be removed. Now the heat accumulation segments 9 be inserted into the circumferential groove 12a.
- FIG 5 shows an annular auxiliary device 21 mounted on the rotor become. This is done through a detachable connection, preferably by means of screws 20.
- the assembly of the Blades 1 then takes place by means of the mounting device 6 exactly the same as described above for the circumferential groove 12a.
- Fig. 6 and Fig. 7 show an economically particularly advantageous Execution of a mounting device 6A, consisting of a head part 31 and a foot part 30. It consists of a Flat material, e.g. made of sheet metal. Parts 30 and 31 can be cut out of the flat material, or by punching out or laser cutting. The foot part 30 then only has to still to be reshaped. The two parts of the head part 31 are connected to the foot part 30 via a seam 32.
- the mounting device 6A is used here for simultaneous and rapid Installation of two blades 1 with inclined axial feet. For this purpose, there are two oblique axial grooves in the mounting device 6A 33 arranged to receive two blade feet.
- the mounting device can be used anywhere with any axial grooves become.
- the number of axial grooves per mounting device is essentially arbitrary. It hangs bsw. from the Blade size, blade weight, rotor diameter and the size of the filling opening.
- the execution of the mounting device is arbitrary, for example. can the foot part from one Solid material can be produced, the head part as in Fig. 6 and 7 from a flat material, or vice versa.
