CA 2335964

The invention relates to a rotor for a turbomachine comprising at least two bladed steps whose discs (4, 5, 6) are detachably connected to one another. A first disc (4) comprises at least one first flange (9, 10) on a lateral surface (7, 8) in order to avoid notch positions in the highly stressed discs. Said flange is connected to or braced against a second flange (17) of an adjacent disc (5, 6) by bolts (14).

L'invention concerne un rotor pour turbomachine, comportant au moins deux étages à aubage, dont les disques (4, 5, 6) sont assemblés de façon amovible. Pour que des points d'entaille soient évités dans les disques soumis à des contraintes élevées, un premier disque (4) comporte, au moins sur une face latérale (7, 8), une première collerette (9, 10) qui est assemblée ou bloquée avec une seconde collerette (17) appartenant à un disque (5, 6) voisin, au moyen de boulons (14).
