Abstract

L’invention concerne un disque (48) de roue aubagée (38) pour turbomachine, s’étendant radialement autour d’un axe (AX) de direction axiale et comprenant en périphérie une pluralité de dents (56) s’étendant radialement et délimitant deux à deux des alvéoles (57) adaptées chacune pour loger un pied (59) d’une aube (49). Les alévoles (57) s’étendent chacune suivant une composante axiale depuis une ouverture (57a) d’introduction du pied (59) de l’aube (49), jusqu’à un fond axial d’alvéole (57b) qui est défini par une couronne (58), cette couronne étant centrée sur l’axe (AX) de direction axiale et formée d’un seul tenant avec les dents (56). Figure pour l’abrégé : Fig . 5
