Abstract
La présent invention porte sur un dispositif anti-usure d'un rotor de turbomachine comprenant un disque (20) avec une jante et des alvéoles (21) axiales usinées sur la jante pour le logement individuel d'aubes, un anneau (43) étant rapporté sur une face de la jante, l'anneau étant percé de trous (44) dans le prolongement axial des alvéoles, au moins une partie desdits trous (44) dans le prolongement des alvéoles étant fermée par un bouchon (50) comprenant une tête métallique (51) formant surface d'appui desdites aubes. Le dispositif est caractérisé par le fait que le bouchon comprend une tige (52) dans le prolongement de la tête métallique, un insert (53) en matériau déformable entourant au moins en partie la tige et un moyen de serrage (54), l'insert en matériau déformable étant déformé par le moyen de serrage de manière à immobiliser le bouchon dans le trou.
