Abstract

L’invention concerne une aube destinée à être montée autour d’un axe sur un disque (1) pourvu d’alvéoles (2), l’aube (5) comprenant une pale (6), un pied (7) destiné à être monté dans un alvéole (2) du disque (1), et une plate-forme radialement interne (8) située radialement entre le pied (7) et la pale (6), caractérisée en que l’aube (5) comporte une partie de retenue (22) configurée pour retenir axialement l’aube (5) vis-à-vis du disque (1), la partie de retenue (22) venant de matière avec l’aube (5) et s’étendant circonférentiellement au-delà de la plate-forme, ladite partie de retenue étant apte à venir axialement en regard du disque (1) lorsque l’aube est montée sur le disque (1). Figure à publier avec l’abrégé : figure 3The invention relates to a blade intended to be mounted around an axis on a disc (1) provided with cells (2), the blade (5) comprising a blade (6), a root (7) intended to be mounted in a cell (2) of the disc (1), and a radially internal platform (8) located radially between the root (7) and the blade (6), characterized in that the blade (5) comprises a part retainer (22) configured to axially retain the blade (5) vis-à-vis the disc (1), the retaining part (22) being integral with the blade (5) and extending circumferentially above beyond the platform, said retaining part being capable of coming axially opposite the disk (1) when the blade is mounted on the disk (1).
