Abstract

L’invention concerne une roue mobile de turbine de turbomachine comprenant un disque (75) présentant sur sa périphérie des dents (81) qui définissent entre elles des alvéoles de logement d’aube. L’invention se rapporte plus spécifiquement à un organe de retenue (91) formant de préférence un anneau fixé contre une face du disque (75). L’organe de retenue (91) délimite axialement au moins une alvéole de manière à obturer celle-ci axialement en définissant une ouverture d’un canal de ventilation (92). L’organe de retenue (91) comprend au moins une dent interne en saillie radialement vers l’intérieur et s’étendant circonférentiellement en vis-à-vis de l’au moins une alvéole. L’ouverture du canal de ventilation (92) de cette alvéole est délimitée radialement à l’intérieur par le fond de cette alvéole et radialement à l’extérieur par cette dent interne de l’organe de retenue (91). Figure pour l’abrégé : Fig. 5
