Abstract

L'invention propose un ensemble aubagé (10) de turbomachine comportant au moins deux aubes (12) adjacentes, chaque aube (12) comportant une pale (14) radiale et une plateforme (16) située à une extrémité radiale libre de la pale (14), dans lequel la plateforme (16) de chaque aube (12) de l’ensemble aubagé (10) est située circonférentiellement en vis-à-vis d’une plateforme (16) de l'autre aube (12) circonférentiellement adjacentes de l’ensemble aubagé (10), dans lequel l‘ensemble aubagé (10) comporte un insert (20) agencé circonférentiellement entre les plateformes (16) et qui coopère avec les plateformes (16), caractérisé en ce que chaque plateforme (16) comporte une face d'appui circonférentielle (32) contre laquelle une extrémité circonférentielle de l'insert (20) est en contact, et en ce que la direction du contact entre chaque face d'appui circonférentielle (32) et l'insert (20) est orientée circonférentiellement par rapport à l'axe principal A.
