Abstract

L'invention concerne un disque (22) pour roue mobile de module de turbomachine d’aéronef, le disque comportant une partie périphérique (24) pourvue de dents (26) s’étendant radialement en rapport à un axe central (2) du disque, les dents (26) délimitant entre elles des alvéoles (32) ouvertes radialement vers l’extérieur et destinées à recevoir des pieds d’aubes. Selon l’invention, au moins l’une des alvéoles (32) est pourvue d’une butée de rétention axiale d’aube (50) destinée à retenir axialement le pied d’une aube associée, la butée de rétention axiale (50) étant réalisée d’un seul tenant avec la partie périphérique (24) du disque. Figure pour l’abrégé : Figure 4.The invention relates to a disc (22) for a moving wheel of an aircraft turbine engine module, the disc comprising a peripheral part (24) provided with teeth (26) extending radially in relation to a central axis (2) of the disc , the teeth (26) delimiting between them cells (32) open radially outwards and intended to receive blade roots. According to the invention, at least one of the cells (32) is provided with an axial blade retention stop (50) intended to axially retain the root of an associated blade, the axial retention stop (50) being made in one piece with the peripheral part (24) of the disc. Figure for abstract: Figure 4.
