Abstract

L'invention concerne un dispositif protecteur (15) pour une pièce à grenailler, sur une turbomachine aéronautique. Ce dispositif comprend un anneau protecteur (17) en matériau élastomère déformable, et un organe de positionnement (19) à diamètre variable. L'organe de positionnement (19) comprend un anneau ouvert, en extrémités libres duquel des plaques (23a, 23b) s'articulent, entre elles et sur l'anneau ouvert entre un état radialement déployé dans lequel les plaques ferment l'anneau ouvert, et un état radialement replié dans lequel les plaques relâchent la sollicitation de l'anneau ouvert.
