Title (EN) DEVICE FOR LIMITING THE LOOSENING OF A NUT IN A TURBINE ENGINE
(FR) DISPOSITIF DE LIMITATION DE DESSERRAGE D'UN ECROU DANS UNE TURBOMACHINE
Abstract:
(EN) The invention relates to an assembly for a turbine engine (1). The assembly includes a mount (4), a nut (3) clamping around the male portion of the mount (4), a member (10) projecting from the mount (4) and a device for limiting loosening of the nut (8, 9). The loosening limitation device (8, 9) includes a member (8) for locking the nut (3) against rotation relative to the mount (4). The rotation locking member (8) includes an inner surface (81) designed to limit rotation of the nut (3) by means of shape engagement with an outer surface (31) of the nut. The rotation locking member (8) includes a first anti-rotation abutment (87) designed to rotatably abut against the projecting member (10). The loosening limitation device (8, 9) includes a translation locking member (9) designed to limit translation of the rotation locking member (8) relative to the nut (3).
(FR) L'invention concerne un ensemble pour turbomachine (1). L'ensemble comprend un support (4), un écrou (3) enserrant la partie mâle du support (4),un organe en saillie (10) du support (4) et un dispositif de limitation de desserrage de l'écrou (8, 9). Le dispositif de limitation de desserrage (8, 9) comprend un organe d'arrêt en rotation (8) de l'écrou (3) relativement au support (4). L'organe d'arrêt en rotation (8) comprend une surface interne (81) configurée pour limiter une rotation de l'écrou (3) par coopération de forme avec une surface externe (31) de l'écrou. L'organe d'arrêt en rotation (8) comprend une première butée anti-rotation (87) configurée pour buter en rotation contre l'organe en saillie (10). Le dispositif de limitation de desserrage (8, 9) comprend un organe d'arrêt en translation (9) configuré pour limiter une translation de l'organe d'arrêt en rotation (8) relativement à l'écrou (3).
