Abstract

Ensemble de rotor à plateformes indépendantes et procédé de montage d’un tel rotor L’invention concerne un ensemble de rotor de turbine de turbomachine comportant : un disque de rotor centré sur un axe X et présentant des alvéoles, des aubes mobiles comprenant chacune un pied monté dans une alvéole, une pluralité de plateformes de maintien des aubes mobiles dans les alvéoles du disque, et un flasque de maintien des aubes mobiles dans les alvéoles, chaque plateforme comportant : une paroi de veine délimitant une veine d’écoulement des gaz, un crochet aval en forme de L avec une portion verticale s’étendant radialement depuis la paroi de veine et une portion horizontale logée dans un crochet de maintien positionné au sommet d’une dent du disque ; etun crochet amont s’étendant sensiblement radialement depuis une zone amont de la paroi de veine et maintenu axialement entre le flasque et le disque. Figure à publier avec l’abrégé : Figure 3
