DEVICE FOR LIMITING THE LOOSENING OF A NUT IN A TURBINE ENGINE

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 rotationlocking 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) includesa 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). 本发明涉及种用于涡轮发动机(1)的组件。该组件包括底座(4)、围绕底座(4)的凸形部分紧固的螺母(3)、从底座(4)突出的构件(10)以及用于对螺母的松动进行限制的装置(8，9)。松动限制装置(8，9)包括用于锁定螺母(3)以防止相对于底座(4)旋转的构件(8)。旋转锁定构件(8)包括内表面(81)，内表面被
