Abstract

L'invention concerne une roue de turbine (10) comprenant : - une pluralité d'aubes (20) ; - un disque (12) à la périphérie duquel sont montés les aubes (20), chacune des aubes ayant une pale (22) solidaire d'une attache (26) engagée dans un logement s'ouvrant à la périphérie du disque et s'étendant axialement entre deux faces opposées du disque (12), les logements ayant un fond et étant séparés les uns des autres par des parties du disque formant des dents (16), et - des dispositifs de retenue axiale (40) des aubes (20) sur le disque (12) comprenant un flasque de retenue exerçant un appui latéral axial sur les dents (16) du disque sur l'un, ou premier, des côtés amont et aval du disque (12), et caractérisée en ce qu'il existe un interstice entre le flasque de retenue (40) et les attaches des aubes (26), et un jeu radial entre les attaches et le fond de leurs logements respectifs de telle manière que de l'air (F) puisse circuler entre le côté amont et le côté aval du disque (12) afin de ventiler le fond des logements.The invention relates to a turbine wheel (10) comprising: - a plurality of blades (20); - a disc (12) at the periphery of which the blades (20) are mounted, each of the blades having a blade (22) integral with a clip (26) engaged in a housing opening at the periphery of the disc and s' extending axially between two opposite faces of the disc (12), the housings having a bottom and being separated from each other by parts of the disc forming teeth (16), and - axial retaining devices (40) of the vanes (20) ) on the disc (12) comprising a retaining flange exerting an axial lateral support on the teeth (16) of the disc on one, or first, of the upstream and downstream sides of the disc (12), and characterized in that there is a gap between the retaining flange (40) and the fasteners of the vanes (26), and a radial clearance between the fasteners and the bottom of their respective housings so that air (F) can circulate between the upstream side and downstream side of the disc (12) in order to ventilate the bottom of the housings.
