Abstract

L’invention concerne une roue, en particulier une roue de turbine, pour turbomachine s’étendant longitudinalement selon un axe X comprenant un disque (98) présentant à sa périphérie une pluralité d’alvéoles (96) s’étendant principalement axialement, une pluralité d’aubes (40, 42), chacune pourvue d’un pied (50) engagé et retenu dans une alvéole (96), chacune des aubes présentant une échasse (48) de liaison du pied (50) à une plate-forme (46), chaque plate-forme (46) d’une aube étant agencée circonférentiellement bout à bout avec une plate-forme (46) d’une aube circonférentiellement adjacente au niveau d’un interstice de jonction entre les plates-formes, lesdites plates-formes (46) circonférentiellement adjacentes délimitant radialement à l’extérieur une veine annulaire d’un flux gazeux, et radialement à l’intérieur une cavité inter-échasse (58) s’étendant circonférentiellement entre les échasses (48) des deux aubes (40, 42) circonférentiellement adjacentes, caractérisée en ce que, pour chaque aube (40, 42), une tôle (64) comprenant une première partie (64a) et une deuxième partie (64b) est telle que :- la première partie (64a) est disposée entre un pied (50) de l’aube et un fond de l’alvéole dans laquelle est engagé ledit pied (50) d’aube, - la deuxième partie (64b) est agencée en vis-à-vis radialement de l’interstice de jonction située entre les plates-formes (46) des deux aubes (42) circonférentiellement adjacentes.
