Definitions

  • a usual shot peening by projection of balls through nozzles oriented towards the part to be treated gives no results on the walls of a cavity as defined above, since the only possible circulation of the balls in the cavity is carried out in a direction substantially parallel to the walls to be treated.
  • the exciter-vibrator is arranged to excite the vibrator at its or at one of its natural frequencies.
  • said tubular part comprises a support flange at its free end.
  • turbine blades 10 are mounted on a disc 11 by means of two nested combs 12 and are made integral with the disc, for example by three pins 13 which are driven into suitable bores made through the disc 11 and the nested combs 12.
  • the bore must be very precise and the condition of the surface is critical, it is necessary to perform a surfacing and a compression stressing of the internal wall of the defined cavity by said bore.
  • This device essentially comprises a vibrator 20 in the form of a pot, one end of which 21 is defined by a tubular element 22 of determined length.
  • a high frequency exciter-vibrator 23 is associated with this vibrator to ensure its excitation.
  • the vibrator 20 and exciter-vibrator 23 assembly is placed at an orifice 25 in this cavity.
  • the tubular element 22 of the vibrator 20 has a diameter slightly smaller than that of the cavity 24 and its end is engaged by a few millimeters in this cavity.
  • the tubular member 22 of the vibrator 20 is provided with a flange 26 of annular shape surrounding the free end of this element. This variant makes it possible to use the vibrator for different diameters of cavities. The flange is pressed against the wall surrounding the orifice 25.
  • FIG. 5 represents the vibrator 20 seen in axial section and makes it possible to understand its operation.
  • This vibrator is excited at its natural frequency or at one of its natural frequencies.
  • the node or one of the vibration nodes 30 occurs in its swollen part 31.
  • the belly or one of the vibration bellies 32 is located at the end of the tubular element 22. The length of this tubular element is determined so as to that a vibrating belly corresponds to its end from where the balls are injected into the cavity.
