The invention relates to a novel solution for mounting a guide vane assembly for a turbomachine turbine, formed of an annular row of fixed flow-stabilizing vanes. According to the invention, the outer edge (11) of the guide vane assembly is axially supported on the extension of the external casing (5, 50) of the turbine, and the inner edge (10) of the guide vane assembly is in sliding axial connection (LG) with the extension of the internal casing (3, 30) of the turbine, the axial sliding connection (LG) allowing the inner edge (10) to be free along the motor axis while the axial stop is achieved by axial contact of the outer edge of the vane.
L'invention concerne une nouvelle solution de montage d'un distributeur d'une turbine de turbomachine, formé d'une rangée annulaire d'aubes fixes de redressement. Selon l'invention, le bord extérieur (11) de distributeur est en appui axial contre la ligne de carter externe (5, 50) de la turbine et le bord intérieur (10) de distributeur est en liaison glissante axiale (LG) avec la ligne de carter interne (3, 30) de la turbine, la liaison glissante axiale (LG) permettant au bord intérieur (10) d'être libre selon l'axe moteur avec l'arrêt axial réalisé par l'appui axial du bord extérieur de l'aube.
