Abstract:
1. An assembly for attachment to the intake of a compressor rotor, said assembly comprising a first piece of the compressor rotor, wherein the first piece ends in a first ring provided with a succession of holes and notches and the axis of the first ring is suitable for being centered on the axis of rotation of the compressor rotor in order to be attached to the intake of the compressor rotor, the first ring is suitable for being placed against an axisymmetric second piece of the rotor, which is fixed to an axisymmetric third piece of the rotor by fastening means and forms a second-piece/third-piece assembly of the rotor, the notches of the first ring being suitable for fitting around the means of fastening the second-piece/third-piece assembly of the rotor, the holes of the first ring being suitable for being placed in alignment with holes of the second-piece/third-piece assembly in order to fasten the first ring to the second-piece/third-piece assembly, wherein the axisymmetric second piece of the rotor is a journal of the compressor rotor.
