Definitions
- the invention relates to a method of surface treatment and setting in compression preload by shot peening of the wall of at least one annular cell substantially in the form of a dovetail, formed at the periphery of a rotor rim, said annular cell opening out the outside by an annular lateral mouth and having at least two cell ends which open into at least one respectively opening for the introduction of blades.
- nozzles can only project microbeads whose diameter is less than 1mm, and typically between 0.3mm and 0.5mm.
- the distribution of the balls, both in position and in speed, is done according to a Gaussian.
- the shot blasting carried out is low so as not to generate a too high roughness in the vicinity of the treated area, which results in limited surface hardening.
- the diameter of the projected balls being small, the stronger the shot blasting, the more the degradation of the state of surface is important.
- the method makes it possible to obtain a homogeneous distribution of the positions beads constituting a mist of beads.
- the fog balls of balls moving in random directions they hit the cavity walls from various angles, which improves the surface condition compared to the balls projected by a nozzle in a preferred direction.
- the displacement is substantially vertically the sonotrode, so that the vibrating surface is at the level of the lateral mouth of the socket.
- the volume in which the fog of balls is distributed being less than the volume obtained when the vibrating surface remains outside the mouth, the process requires a shot blasting treatment time shorter.
- At least three successive shot blasting operations are carried out of the wall, reversing the direction of rotation of the rotor rim each time approach one end of the cell.
- the entire wall of the annular cell is not subject to same time to the impact of balls, which entails risks of deformation of the cavity, in particular, of the socket containing the foot dawn, given the importance of the rim diameter in relation to its thickness. Treating the wall with three successive treatments allows to considerably compensate for the deformations of the rim.
- a deflector is placed in the enclosure.
- the deflector can be of substantially triangular geometry with sides parallel to the portions of divergent walls so as to reduce the blasting effect of the area between said deflector and the bottom of the cavity.
- the rotor part after having shot a first cell, we do turn the rotor part around its axis of rotation, so as to bring the closure means in the opening for introducing blades, the displacement is substantially vertically the sonotrode and the sheath towards the position low, the acoustic assembly is moved substantially horizontally comprising the sheath and the horn towards the opening for introducing a second annular cell which is brought opposite the sonotrode, and we again positions the sonotrode supporting the dose of beads and the sheath in their high shot blasting position for blasting said second annular cell.
- the dose of beads is easily retrieved in order to be either reused for a subsequent treatment, or be replaced.
- a dose of balls is used whose diameter is greater than 0.8mm.
- the balls used in the process according to the invention have a diameter larger than the diameter of the balls likely to be projected by a nozzle, so the shot blasting can be stronger while having a less significant surface degradation.
- the invention also relates to an installation for setting up implement the process.
- the installation may include a plurality of acoustic assemblies each comprising a sonotrode and a sheath, arranged around the rim rotor, said acoustic assemblies being able to move in a axial direction of the rotor rim.
- the installation comprises a third lower clearance the diameter of the balls formed between said vibrating surface arranged in said mouth and said mouth.
- the installation advantageously comprises a fourth lower set the diameter of the balls formed between one end of the sheath and the mouthpiece, which when the vibrating surface does not block the mouthpiece ensures the tightness of the enclosure.
- the various elements of the installation are arranged so that no ball can block said elements likely to move.
- the sonotrode and the sheath comprising the closure means have a geometry adapted to the shape of the cavity to be treated.
- the vibrating surface is of complementary shape to the mouthpiece and the means shutters are formed so as to properly seal the enclosure.
- the second displacement means are likely to move the shutter means and the sonotrode together.
- the first means of movement and the second means of displacement are advantageously able to be controlled simultaneously.
- the sheath and the sonotrode are placed in an intermediate position in which the space generated by the means for closing said sheath and the vibrating surface of said sonotrode constitutes a reservoir for the dose of beads. Then said sheath and said sonotrode supporting the dose of beads are moved together using of the same displacement. Finally, the sonotrode and / or the sealing means can be moved individually, depending on the geometry of the cavity to be treated until the vibrating surface respectively closes the mouth of the cavity and that the sealing means close off the cavity openings.
- the installation includes support means to support the rotor rim to be treated and drive means said support means for regularly rotating the cell annular.
- the installation advantageously includes means for expelling the dose of balls from the vibrating surface to a reservoir.
- the installation includes means for moving substantially horizontally the sonotrode and the sheath.
- a plurality of annular cells arranged indifferently on a rotor rim and having the same sections, can thus be treated with a same installation that is moved so as to position the sonotrode and the sheath opposite the cell in question.
- FIG. 1 shows a rotor rim 1 comprising three cells annulars 2, formed at the periphery of the rotor rim 1 and distributed over different diameters of said rotor rim 1.
- These annular cells 2 are substantially dovetail-shaped and have a 2A mouthpiece substantially annular in shape.
- said cell 2 has a blade opening opening 5 visible in FIG. 3.
- Each blade root 4 is successively mounted by sliding in the insertion opening 5.
- One or more fixing device blades (not shown) allows the blades to be blocked 6.
- Figure 2 shows that the support between the walls of the cell 2 and the blade root 4 results in two contact lines 2B.
- the object of the invention is to propose a method and an installation to put in compression preload the wall 2C of each cell 2 and in particular the areas of the two contact lines 2B, so as to increase the wear resistance of these 2B contact lines caused by the friction between the blade root 4 and the wall of the cell 2 and so increase the fatigue strength of the rotor rim 1.
- Figure 3 shows an example of installation used for setting up process work and in which only one acoustic unit is used, said acoustic assembly positioned below the rotor rim 1 being likely to move vertically and horizontally.
- the rotor rim 1 is held by a mandrel 7 which can drive said rotor rim 1 rotating around its axis of rotation 1A, disposed at the horizontal.
- a sonotrode 8 the vibrating surface 8A of which is placed in a intermediate position in a sleeve 16, is movably mounted under the rim rotor 1.
- a dose of balls is placed above the vibrating surface 8a.
- the acoustic assembly comprising the sonotrode 8 and the sheath 16 is moved horizontally until the vibrating surface 8A of the sonotrode 8 is opposite cell 2 to be treated.
- the sonotrode 8 and the sheath 16 are moved vertically towards their high shot blasting position and the rotor rim is rotated to bring the vibrating surface 8A in the vicinity of a first end cell, 5A for example, so that shutter cheeks 14A and 14B formed on the sheath 16 are placed in the cell 2 so as to form a closed mobile enclosure 12.
- said movable enclosure 12 is delimited by the wall portion 2'C, the vibrating surface 8A which closes the mouth portion 2A, the closing cheeks 14A and 14B and the sheath 16.
- the distance L1 between the two shutter cheeks 14A and 14B is substantially equal to the circumferential extent L2 of the opening introduction 5.
- Balls 10 with a diameter between 0.8mm and 5mm, preferably equal to 1mm, are projected by the vibrating surface 8A, oriented upwards, of the sonotrode 8 in the enclosure 12.
- FIG. 5 shows that the vibrating surface 8A is excited by a vibration generator 18, for example quartz, in order to create a fog of balls 10 in the enclosure 12.
- a deflector 15 which is carried by the shutter cheeks 14A and 14B can be placed in the fog of balls 10 in order to mitigate the blasting effect of the bottom of the cell and increase the shot blasting of the internal sides of the mouthpiece 21.
- Said deflector 15 is triangular with sides substantially parallel to the 2'C wall portions and at the bottom of the cell.
- the clearance e1 formed between the sonotrode 8 and the sheath 16 is less the diameter of the balls 10, so that no ball 10 can pass between the vibrating surface 8A and said sheath 16.
- the shutter cheeks 14A and 14B in dovetail shape have axial sections substantially complementary to those of cell 2, so that in the high shot peening position, the clearance e2 formed between each end cap 14A, 14B, and the portion of wall 2'C to be blasted is smaller than the diameter of the balls 10. Thus, no ball 10 can escape outside the enclosure 12.
- a first slide 20 makes it possible to carry out the displacements sonotrode 8 vertical by sliding said sonotrode 8 in the sheath 16.
- Control means allow control said first slide 20 and said second slide 22.
- Means for example rails, used to move the assembly acoustic comprising the sonotrode 8 and the sheath 16 horizontally, so as to position it next to a cell to be treated.
- the first slide 20 can be carried either by the second slide 22, as shown in Figure 5, either by the frame 24, in which case the control of the two slides 20 and 22 must be synchronized to mount together the sonotrode 8 and the sheath 16 towards the high position of shot blasting.
- the sonotrode 8 Before starting the treatment operation of an axial cell 2, the sonotrode 8 is placed in an intermediate position in the sheath 16, position in which the space delimited by the sheath 16 and the surface vibrating 8A, constitutes a container 26 which makes it possible to contain the dose of balls 10 which is deposited on the vibrating surface 8A, as shown in the figure 6.
- the sonotrode 8 and the sheath 16 are moved to the neighborhood of a first cell 2 to be treated and the opening is brought introduction 5 of said first cell 2 opposite the sonotrode 8, in rotating the rotor rim 1 around its axis of rotation 1A using drive means (not shown).
- Means of training include for example a motor.
- the sonotrode 8 and the sheath 16 are moved to their high position shot blasting by simultaneously moving, using the slide 22, the shutter cheeks 14A and 14B and the vibrating surface 8A in the opening 5, then rotate the rotor rim 1 until the two cheeks 14A and 14B are in the end 5A for example. Therefore, we proceeds to the peening of the wall portion 2'C of the first cell 2 in actuating the vibration generator 18 which generates a fog of balls 10 in the sealed mobile enclosure 12 and the rim is rotated regularly of rotor 1 around its axis of rotation 1A so as to blast the entire wall 2C.
- the sonotrode 8 is withdrawn towards its position low, represented figure 7, in which one proceeds to the release of the dose of balls 10.
- the balls 10 are for example blown from the surface 8A using a blower 28 through lights 30 formed in the sheath 16 and recovered in a tank 32. Said balls 10 can then be refreshed or replaced for further processing.
