Abstract

Est concerné un ensemble de rotor de turbomachine comprenant un disque de rotor (20) adapté à tourner autour d’un axe (X) et présentant en périphérie des alvéoles (50) présentant chacune un fond ; des aubes (90) présentant des pieds (110) disposés individuellement dans lesdites alvéoles; et des cales (130) chacune interposée entre un pied (110) d’une desdites aubes et le fond (70) d'une alvéole. Les cales (130) intègrent des dispositifs amortissants (52) à effet de rappel, pour repousser radialement vers l’extérieur les pieds (110) d’aubes. Figure à publier avec l’abrégé : figure n°3This concerns a turbomachine rotor assembly comprising a rotor disk (20) adapted to rotate around an axis (X) and having on the periphery cells (50) each having a bottom; blades (90) having legs (110) arranged individually in said cells; and wedges (130) each interposed between a foot (110) of one of said blades and the bottom (70) of a cell. The wedges (130) integrate damping devices (52) with a return effect, to push the blade roots (110) radially outwards. Figure to be published with the abstract: figure n°3
