Definitions
- the invention relates to a method for replacing a blade of a rotor with integral blading and a rotor with a blade exchanged in this way.
- Rotors with integral blading have either a disk-shaped or an annular rotor body, on the outer periphery of the blading is integrally arranged.
- Rotors with a disk-shaped rotor base body are referred to as blisk (bladed disk) and rotors with an annular rotor base body as bling (bladed ring).
- rotors with integral blading are described in the patent application WO 2005/024185 of the applicant.
- One method is to mill the rotors with their Beschaufein from the solid.
- Another manufacturing method provides to produce the blading separately from the rotor body and then to arrange by a joining method to the rotor body. Examples of joining methods are linear friction welding, inductive pressure welding or diffusion welding.
- the blading consists of forgings, which are already adapted to the desired shape of the blade so that after attaching to the rotor body has to be done only a fine machining.
- the blading may also consist of a plurality of blade blanks, which are separated out of a press profile and are processed to their desired shape only after attachment to the rotor body.
- the international patent application WO 2008/046388 of the applicant describes a
- a known method for replacing a damaged blade of a rotor with integral blading is disclosed in the German patent application DE 10 2005 033 625 A1 of the applicant. According to this method, the damaged blade is separated and replaced with a new blade made by a powder metallurgical injection molding process. However, DE 10 2005 033 625 A1 does not disclose whether the new blade is arranged directly on the outer circumference of the rotor base body or whether it is attached to a rotor body-side stump of the previously separated damaged blade.
- DE 39 09 733 A1 proposes a method for replacing a blade, in which the new blade is welded to a rotor body-side stump.
- the damaged blade is separated at a defined distance from the rotor base body so that a stump remains whose radial surface represents a blade connection surface for the new blade.
- the stump is circumferentially stabilized by a multi-part metallic enclosure, which enters into a metallurgical connection with the stump and the Neuschaufel.
- the height of the enclosure corresponds to the radial length of the stump so that the stump and the enclosure provide the blade pad for the new blade.
- EP 1 535 692 B1 also describes a method for exchanging a
- EP 0 376 874 B1 instead of stabilizing the rotor base body-side stump, to provide the new blade in the region of its joining surface with a collar which allows uniform heating during joining and is intended to prevent deformation.
- the separation of the damaged blade can be done by means of Electrical Discharge Machining (EDM method). After joining the Neuschaufel the collar and excess material is removed and finished the connection stump Neuschaufel to nominal size.
- EDM method Electrical Discharge Machining
- US Pat. No. 6,095,402 shows a method for exchanging a rotor with integral blading, in which a new blade is also arranged on a rotor base-side stump of a previously separated damaged blade.
- the subject of this US patent is directed to the particular geometric design of the blade connection surface of the stub, so that even with non-planar blade connection surface, the Neuschaufel can be joined by means of linear friction welding.
- the aforementioned known method is the same that the radial blade connection surface of the stump is formed during the separation of the damaged blade.
- a separation surface created when the damaged blade is cut off at the stump serves as a blade connection surface for a new blade.
- the separating surface is merely cleaned to prepare for joining.
- This has the disadvantage that the separation of the damaged blade at a defined distance from the outer circumference of the rotor base body and in addition has to be done very accurately to allow a precise fit joining the Neuschaufel. Accordingly technically demanding separation methods are to be used.
- the stump has to be stabilized consuming during the joining or the Neuschaufel has special design features, since the finished form of the stump does not withstand the loads occurring during joining.
- Object of the present invention is to provide a method for replacing a blade of a rotor with integral blading, which eliminates the aforementioned disadvantages and allows easy custom-fit joining a Neuschaufel, and to provide a rotor with such a replaced blade.
- This object is achieved by a method for replacing a blade of a rotor with integral blading with the steps of claim 1 and by a rotor having the features of claim 10.
- a first step the old blade is separated from the rotor base body.
- a separation surface is formed on the rotor base body, on which, according to the invention, a pedestal is erected in a following step.
- the blade connection surface for a new blade is formed on its radial surface facing away from the rotor base body. Then the Neuschaufel is grouted to the blade pad.
- An advantage of the method according to the invention is that the blade connection surface is newly formed and not, as known from the prior art, is identical to the separating surface on the rotor body side during separation of the old blade.
- the old bucket can be removed by technically simple separation of the rotor body.
- the old bucket can not be separated too close to the outer circumference of the rotor body, since the Neuschaufel is not joined directly to the remaining stump, but a pedestal is built, the radial length is arbitrary.
- a complex stabilization of the base during joining is not necessary, since its shape can be chosen flexibly when erecting or building.
- the pedestal may be conditioned in shape such that the joining and finishing of the new bucket corresponds to placing a bucket in the manufacture of new parts.
- the old bucket is separated from the rotor base body in such a way that the separating surface is formed on a stump on the rotor body side.
- the old bucket is removed from the rotor base body in such a way that the separating surface runs flush with the outer circumference of the rotor base body.
- the base can be oversized both in the circumferential direction and in the axial direction.
- the joint connection per se and the shape of the Neuschaufel a finishing can be performed on nominal size.
- the construction of the base takes place by means of a generative manufacturing process, for example by laser deposition welding.
- the joining of the new blade to the blade connection surface is carried out in one embodiment by means of a welding process.
- a welding process examples are electron beam welding, linear friction welding, inductive high frequency pressure welding or diffusion welding.
- An inventive rotor with integral blading provides a Rotor ground- body on which a plurality of blades is arranged, wherein at least one old bucket is replaced by a Neuschaufel.
- the new blade is arranged on a blade connection surface of a base, which is erected on a rotor body-side separating surface of the previously separated old blade.
- FIG. 1 shows a cross section through a rotor in the manufacture of new parts with integral blading in the area of a joined blade
- FIG. 2 shows the cross section of Figure 1 after a completion of the joint connection
- 3 shows a cross section through a rotor with integral blading in the region of a separated old blade
- FIG. 4 shows the cross section according to FIG. 3 before the joining of a new scoop
- FIG. 5 shows the cross section according to FIG. 4 after joining the new blade
- Fig. 6 shows the cross section of Figure 5 after finishing the joint connection.
- FIG. 1 shows in simplified form the manufacture of a rotor 2 of a gas turbine, in particular of an aircraft engine, with integral blading.
- the rotor 2 has a disc-shaped rotor base body 4 with a plurality of radial projections 6, 8, 10, on each of which a blade 12 of the integral blading is joined directly or is still joined.
- a central projection 8 with the blade 12 shown in FIG. 1 will be considered below by way of example for each projection 6, 8, 10 and for each blade 12.
- the projection 8 has a radial blade connection surface 14 and is provided with an oversize indicated in FIG.
- the bucket 12 has a foot portion 16 and a head portion 18 remote from the foot portion 16, here provided with a shroud.
- the foot section 16 has a joining surface 20 facing the rotor base body 4 and, in accordance with the radial projection 8, is provided with an oversize shown in dashed lines in FIG.
- the joining surface 20 is complementary to the blade connection surface 14 of the radial projection 8.
- Suitable joining methods are, for example, electron beam welding (EB), linear friction welding, inductive high-frequency pressure welding (IHFP) or diffusion welding.
- the projection 8 and the foot section 16 of the blade 12 are brought to their final dimensions by a finishing operation.
- the oversized dimensions of the projection 8 and of the foot section 16, indicated by dashed lines, as well as accumulations of material occurring during joining, are removed.
- Exemplary finishing processes include electrochemical machining (ECM) and milling.
- FIG. 3 shows a cross section through a rotor 2 with integral blading. There is shown a rotor base 4 with two undamaged blades 24, 26, between which an old blade 12 shown in FIG. 2 was arranged. The joining of the shovel 24, 26 and the joining of the old bucket 12, not shown in FIG. 3, took place in the course of the manufacture of new parts as explained above in FIGS. 1 and 2.
- a parting plane 28 is determined, in which the old bucket 12 is to be separated from the rotor body 4.
- the course of the parting plane 28 is selected such that a stump 30 of the radial projection 8 shown in Figure 1, on which the old blade 12 was arranged, rotor rotor body side stops.
- the removal of the old bucket 12 from the rotor body 4 was carried out, for example, by electrical discharge machining (EDM).
- the stump 30 has a radial separation surface 32 lying in the parting plane 28, on which, according to FIG. 4, a radial base 34 for receiving the new blade 22 is erected.
- the stump 30 is smaller than the original projection 6 is formed. Its height or radial length can be adjusted arbitrarily.
- the construction of the base 34 takes place by means of a generative production method. rens, for example by laser beam or laser deposition welding. When erecting, the base 34 forms a metallurgical connection with the rotor base body 4.
