Abstract

Le dispositif de commande est d'un coût de fabrication relativement faible.Il comprend principalement une première extrémité (46) d'un levier de commande (40) possédant un trou d'entraînement (45) qui entraîne, par une première zone de contact (41) la partie d'entraînement (16) d'une aube (10). Le contact intime à cet endroit, entre ces deux pièces, est obtenu par l'intermédiaire d'une tôle de rattrapage de jeu (50) prenant appui contre une partie latérale (47) du levier de commande (40) et fixée sur l'ensemble par un écrou (60) vissé sur le pivot extérieur (11) de l'aube (10).Application aux turbomachines.
