Abstract
L'invention concerne un accouplement pour turbomachine, comportant un premier et un deuxième disque (17, 18) accolés le long d'un axe (AX), et s'étendant en majorité respectivement d'un premier et d'un deuxième côté (C1, C2) d'un plan médian (PM) normal à l'axe (AX), le premier et le deuxième disque (17, 18) étant pourvus respectivement de premières et de deuxièmes dents (19, 21) s'engageant mutuellement à travers le plan médian (PM) pour former une liaison curvic. Selon l'invention : - plusieurs premières dents (19) comportent chacune une première protubérance (19b) dépassant vers l'axe (AX) en s'étendant du deuxième côté (C2) ; - plusieurs deuxièmes dents (21) comportent chacune une deuxième protubérance (21b) dépassant vers l'axe de rotation (AX) en s'étendant du premier côté (C1); - les premières protubérances (19b) sont espacées des deuxièmes protubérances (21b) le long de l'axe (AX) ; - au moins un organe de blocage est rapporté en appui contre des premières et deuxièmes protubérances (19b, 21b) pour bloquer axialement le premier élément (17) relativement au deuxième élément (18).The invention relates to a coupling for a turbomachine, comprising a first and a second disc (17, 18) contiguous along an axis (AX), and extending for the most part respectively from a first and a second side ( C1, C2) of a median plane (PM) normal to the axis (AX), the first and the second disc (17, 18) being provided respectively with first and second teeth (19, 21) mutually engaging through the midplane (PM) to form a curvic bond. According to the invention: - several first teeth (19) each comprise a first protuberance (19b) projecting towards the axis (AX) while extending from the second side (C2); - Several second teeth (21) each comprise a second protuberance (21b) projecting towards the axis of rotation (AX) extending from the first side (C1); - the first protuberances (19b) are spaced from the second protuberances (21b) along the axis (AX); - at least one locking member is fitted to bear against first and second protuberances (19b, 21b) to axially block the first element (17) relative to the second element (18).
