Abstract

ROUE MOBILE POUR TURBOMACHINE COMPRENANT DES AUBES MONTÉES RADIALEMENT ET BLOQUÉES AXIALEMENT Un aspect de l’invention concerne une roue mobile (200) pour turbomachine, comprenant : un disque (1) présentant un axe de rotation et comprenant des alvéoles (11) ;des aubes comprenant chacune un pied de fixation (21) logé dans une alvéole (11) ; une entretoise (4) fixée au disque (1). L’alvéole (11) est configurée pour permettre une insertion radiale du pied de fixation (21) et comprend une paroi de blocage axial (11d) en contact avec une surface de blocage axial (21d) du pied de fixation (21). La surface de blocage axial (21d) et la paroi de blocage axial (11d) bloquent axialement, dans une première direction (D1), le pied de fixation (21) dans l’alvéole (11). L’entretoise (4) bloque axialement, dans une deuxième direction (D2) opposée, le pied de fixation (21) dans l’alvéole (11). Figure à publier avec l’abrégé : Figure 7
