Abstract

L’invention concerne un ensemble de fixation d’un pied d’aube dans l’alvéole d’un rotor de soufflante de turbomachine. Cet ensemble comprend - un carter (30) présentant une surface d’appui munie d’une alternance de cavités et d’élévations,- une cale (40) présentant une surface d’appui munie d’une succession de cavités et d’élévations disposées en alternance,- une pluralité d’éléments de roulement (50),- et un dispositif de déplacement actionnable pour entrainer le déplacement de la cale (40) et/ou du carter (30), de sorte que les éléments de roulement (50), la cale (40) et le carter (30) passent d’une position de repos, dans laquelle chaque élément de roulement (50) est logé dans une cavité du carter (30) et dans une cavité de la cale (40), à une position active, dans laquelle chaque élément de roulement (50) est positionné au contact d’une élévation de la cale (40), de façon à provoquer le déplacement de la cale (40) et du pied d’aube en direction de l’ouverture radialement externe de l’alvéole.
