Definitions
- the invention relates to the assembly of blades at the periphery of a disk of a turbomachine, which may occur during assembly of the turbomachine.
- the invention will be particularly suitable for disks that belong to a turbine engine low-pressure turbine. It relates to a mounting method, as well as a particular tool allowing the implementation of the method.
- turbomachine In the context of the assembly of the parts of a turbomachine, for commercial purposes of complete production of the turbomachine for sale, or experimental for testing, testing or experimentation of the turbomachine or partial elements of the latter, it involves a step of blade assembly on the periphery of a turbomachine disk.
- the disc is a rotating part of the turbomachine attached to the low pressure shaft or the high pressure shaft of the turbomachine.
- the blades once mounted on the disc, allow the transfer of energy between the flow through the secondary vein of the turbomachine and one of these trees.
- the disk comprises at its periphery cells oriented substantially parallel to the axis of the disk, and arranged alternately with the teeth of the disk.
- the blades comprise at their inner ends feet which, one faith inserted in the cavities of the disc, are retained radially by shape cooperation by the teeth of the disc.
- the blade roots are further extended radially by blades, then by heels constituting the outer ends of the blades.
- the heels generally comprise external wipers, that is to say outer radially projecting walls which are intended to cooperate with a radially outer element of the turbomachine.
- the heels may further include axial spoilers, i.e. axial walls intended to extend into upstream and / or downstream of the heel in the turbomachine to delimit the outer limit of the secondary vein.
- vanes and the disc In order to assemble the vanes and the disc, at first all the vanes to be mounted on the disc, aligned end to end circumferentially, are assembled in a configuration similar to their final state mounted on the disc. This "crown" of blades is then positioned in front of the disk so that the blade roots are axially facing the corresponding cells of the disk. The assembly is done by axial displacement of the blades, one by one, to insert the feet axially into the cells.
- foils are arranged around the blade roots to serve as an interface between the feet and the cells and thus avoid their respective wear.
- the assembly of the blades is however made difficult by the shape of the heels.
- the heels are oriented so as to be in circumferential supports on each other along a direction which is not the same as the direction of introduction of the blade roots into the cells.
- the heel of this blade is blocked in axial displacement by the heels of the adjacent blades.
- EP2460980 teaches that blades may be introduced into cells in the radial direction of the rotor body by a device to be put in place in the region of the blade roots. This imposes operational constraints. And no information on the device in question is provided.
- the present invention provides a simple, effective and economical solution to facilitate the mounting of the blades on the disc.
- the disc comprising, at its radially outer periphery, cells that extend substantially parallel to the axis of the disc and arranged alternately with teeth of the disc,
- the blades comprising respectively:
- the vanes of the vanes are circumferentially supported on each other along flanges oriented in a direction different from that in which the blade roots are oriented. .
- the method involves as many blades to be mounted on the disk as disk cells, and the steps (b), (c), (d) and (e) are repeated successively for all the blades.
- all the blades are of identical shapes, and one and the same mounting tool is used during the repetition of steps (b), (c), (d) and (e).
- step (a) Prior to step (a), it is possible to mount a foil around the foot of the dawn, the foil being inserted with the foot of the dawn into the cell during step (e).
- the foil reduces wear on blade roots and cells.
- the mounting tool comprises gripping means such as a handle.
- the gripping means and the tip of the mounting tool are removable relative to each other. It is thus possible to manufacture several complementary tips to different types of blades, while using the same gripping means that can be connected to each of these tips.
- the tip of the mounting tool comprises two axial stops between which are adjusted with a small clearance the axial ends of the heel during step (c). During step (c), the heel is thus taken by the mounting tool between the two stops, which implies that a rotation of the tool causes contact reaction a rotation of the heel.
- the tip of the mounting tool comprises at least one slot in which is adjusted with a small clearance at least one lick of the heel of the blade during step (c). This allows the mounting tool to ensure an even better grip on the heel when rotating.
- the invention further relates to a blade mounting tool for mounting vanes at the periphery of a turbomachine disk as described above, comprising a tip shaped in part complementary to the heel of a blade, so as to ability to rotate the heel and the mounting tool in rotation, in particular around the direction of extension of the blade which corresponds to the alignment direction between the foot, the blade and the heel.
- the tip may comprise a face from which two shoulders facing one another face the axial ends of the heel of a blade, said face further comprising, between the two shoulders, at least one slot oriented substantially in parallel. to the shoulders, and intended to cooperate with a lash of the heel of a blade.
- FIG. 1 is a side view of a blade to be mounted on a turbomachine disk
- FIG. 2 is a view of a foil adapted to the base of the blade of Figure 1;
- FIG. 3 is a view of the disk and vanes at the end of step (a) of the invention.
- FIG. 4 is a magnification of the framed zone of FIG. 3;
- FIG. 5 is a tip of complementary shape to the heel of the blade of FIG. 1;
- FIG. 6 is a view of the complete assembly tool comprising the tip of FIG. 5;
- FIG. 7 is a diagram of use of the mounting tool according to the invention.
- a blade 10 is described intended to be mounted on a turbomachine disk 12. More particularly, the blade example shown, and disk thereafter, corresponds to a low-pressure turbine stage of the turbomachine.
- the blade extends longitudinally in a so-called radial direction, with reference to the radius of the turbomachine axis 16.
- the radially inner portion of the blade is a foot 14, intended to be mounted in a cell 18 of a disk , and extended externally by a stilt 20, then by a platform 22, then by a blade 24, and finally by a heel 26.
- the heel is composed of a platform 28 and further comprises on its outer face wipers 30, which are walls extending substantially radially outwardly and circumferentially.
- the blade is intended to interact with the flow of gas passing through the turbomachine in order to exchange the energy with the disk 12.
- the two platforms 22, 28 are walls that extend cylindrically on either side of the turbine. dawn 10, and respectively delimit internally and externally the vein where the flow of gas flows.
- Spoilers 32, 34 further extend upstream and downstream of the inner platform 22 and the outer platform 28 for the same purpose.
- the root 14 of the blade has a shape of bulb substantially complementary to the shape of a cell 18 of the disc 12. It is usual to mount a foil 36 on the root 14 of each blade 10, that is to say a wall that surrounds the foot while conforming to its shape, and which will protect against wear the walls of the foot and the cell in which it is mounted.
- All the blades 10 are offset axially with respect to their final positions, so that the feet 14 of the vanes are axially facing the cells 18 of the disc 12 before assembly.
- FIG. 5 shows the end piece 40 of the mounting tool 50 according to the invention, which is complementary in shape to the heel 26 of one of the blades 10, and can be used to drive the heel 26 in rotation about the radial direction.
- the tip 40 is provided to engage the outside of the heel 26. The tip comes to marry by the outside the shape of the heel with a small clearance, so that any rotation of the tip 40 around the radial direction causes, by contact reaction with the parts engaged with the heel 26, the rotation of the heel. It will be readily appreciated that the more complete and adjusted the shape cooperation between the end piece and the heel, the more the contact reaction will be distributed over the whole of the heel 26, which avoids excessive concentrations of mechanical stresses.
- the endpiece has an internal face 42 which rests on the external face of the heel 26. and downstream of the tip are flanges 44 inwardly forming, face to face, two shoulders upstream and downstream substantially perpendicular to the inner face 42 of the nozzle. Its shoulders are spaced so as to abut against the upstream and downstream ends of the upstream and downstream spoilers 34 of the heel 26, when the mounting tool is engaged.
- the inner face 42 of the tip 40 comprises between the two shoulders 44, at least one slot 46, generally two slots 46, extending circumferentially in the tip and oriented substantially parallel to the shoulders, the or each slot having a complementary shape and fitted to each of the wipers 30 of the heel, which are introduced when the mounting tool is engaged.
- the tip 40 can be connected to gripping means 48, such as a conventional handle. This connection is removable in order to retain the same gripping means 48 for different types of tips 40 which correspond to other types of blades 10 than those given in example. It can be clearly seen in FIG. 6 that the mounting tool engages outside the blade 10, and leaves the circumferential edges of the heel 26 free while engaging the upstream and downstream edges of the heel 26.
- FIG. 7 shows how the mounting tool 50 is used to engage the blades 10 in the cavities 18 of the disk 12. While the engagement direction 52 of the blade roots 14 in the cells 18 is slightly inclined by relative to the axis 16 of the disk, just like the circumferential rims of the inner platforms 22 of the blades 10, it can be seen that the external platforms 28 of the blades 26 have their circumferential flanges aligned and supported on each other. others in the strictly axial direction. This difference in inclination means that it is in the natural state impossible to engage the blades 10 in the cells 18 without the heels 26 of the blades interfere with the movement.
