1. A device for axial locking of a moving part with respect to a reference part, an annular cavity being defined between the reference part and the moving part, the reference part extending along a reference axis, the reference part comprising a groove and a support shoulder extending transversally to the reference axis, the moving part comprising a transversal slot delimited by a downstream edge and an upstream edge, the upstream edge comprising circumferential openings, the axial locking device comprising:
a downstream locking wedge constructed to be inserted into the annular cavity, the downstream locking wedge being provided with lugs laid out such that the downstream locking wedge can be placed in:
a first angular position in which the downstream locking wedge may be translated axially through the circumferential openings of the upstream edge, anda second angular position in which the lugs immobilise axially the downstream locking wedge in the slot axially resting against the downstream edge and the support shoulder; an upstream locking wedge constructed to be inserted into the annular cavity until it comes into axial abutment against the downstream locking wedge, the upstream locking wedge being laid out to prevent the rotation of the downstream locking wedge in the slot when the upstream locking wedge is in axial abutment against the downstream locking wedge; a stop segment constructed to be inserted into the annular cavity and to be inserted into the groove so as to immobilise axially the upstream locking wedge against the downstream locking wedge. |
