Definitions

  • the invention relates to a device for axially and radially retaining the blade of a turbojet rotor, capable of avoiding the matting of the blade roots and of the air cells, and more particularly of a wedge capable of being housed between the base of the 'blade and the bottom of the groove provided in the rim of the rotor disc.
  • the tool is then dismantled maintaining the stress exerted between the part 15 and the blade 16, which places the horizontal face of the dihedron 28 in abutment on the bottom 14 of the groove 2 and the vertical face of the dihedron 28 in abutment on the face upstream of the disc 1.
  • the shim 13 is thus locked in the axial direction from upstream to downstream. Locking in the opposite direction, from downstream to upstream, can be ensured in a known manner by a flange of the front cover coming to rest against the end 19 of the wedge.
