Abstract

Le dispositif de blocage d'aubes à attache marteau dans la rainure (2) d'un disque (1) de roue de turbomachine comporte un corps (15) dont la section est conformée à la section de la rainure (2), un élément de verrouillage (16) monté radialement mobile dans un orifice traversant prévu dans le corps (15) et susceptible de loger en partie dans un logement de verrou (9a, 9b), et une vis de manoeuvre (17) de l'élément de verrouillage (16). L'élément de verrouillage (16) comporte des butées (32a) coulissant dans des fenêtres (22a) du corps (15). La tête de vis (41) est de grande dimension et est radialement immobilisée entre le fond de la rainure (2) et l'embase (20) du corps (15). Figure 3.
