Abstract

Roue de rotor (50) de turbine, en particulier contrarotative, pour une turbomachine d’aéronef, comportant : - un disque de rotor (52), - une virole annulaire (54) ; - des aubes (56) disposées entre ledit disque et ladite virole, et comportant chacune un pied situé du côté dudit disque et un sommet situé du côté de ladite virole, caractérisée en ce que les sommets des aubes sont solidaires d’un premier anneau (60) qui comprend des cannelures externes (63b) engagées dans des cannelures internes (63a) de ladite virole afin d’assurer une transmission d’un couple de rotation entre la virole et les aubes, et en ce que les pieds des aubes sont solidaires d’un second anneau (62) qui comprend des cannelures internes (64b) engagées dans des cannelures externes (64a) dudit disque afin d’assurer une transmission dudit couple de rotation entre les aubes et le disque. Figure pour l'abrégé : Figure 3Turbine rotor wheel (50), in particular counter-rotating, for an aircraft turbomachine, comprising: - a rotor disk (52), - an annular shroud (54); - blades (56) arranged between said disc and said ferrule, and each comprising a foot located on the side of said disc and a vertex located on the side of said ferrule, characterized in that the vertices of the blades are integral with a first ring ( 60) which comprises external grooves (63b) engaged in internal grooves (63a) of said shroud in order to ensure transmission of a rotational torque between the shroud and the blades, and in that the roots of the blades are integral a second ring (62) which comprises internal grooves (64b) engaged in external grooves (64a) of said disk in order to ensure transmission of said rotational torque between the blades and the disk.
