Title (EN) NUT-LOCKING DEVICE AND ASSOCIATED ASSEMBLY UNIT
(FR) DISPOSITIF DE BLOCAGE D'ÉCROU ET ENSEMBLE DE MONTAGE ASSOCIÉ
Abstract:
(EN) The invention concerns a unit (210) for a locking device, comprising: a nut (212) comprising two coaxial taps in opposite directions; and a ring (213); said ring including a third tap (38); the first (18) and third (38) taps being capable of engaging with a single first thread (22); said ring including a second thread (40) capable of engaging with the second tap (20) of the nut. The unit further comprises a washer (214) configured (274) so as to be inserted around one (212) of the nut and the ring, the washer comprising an elastic engagement means (272) for engaging with the other (213) of the ring and the nut in an installation position of the unit, so as to prevent the ring and the nut from rotating relative to each other.
(FR) L'invention concerne un ensemble (210) pour dispositif de blocage, comportant : un écrou (212) comprenant deux taraudages coaxiaux et de sens opposé; et une bague (213); ladite bague comportant un troisième taraudage (38); les premier (18) et troisième (38) taraudages étant aptes à coopérer avec un même premier filetage (22); ladite bague comportant un deuxième filetage (40) apte à coopérer avec le deuxième taraudage (20) de l'écrou. L'ensemble comporte en outre une rondelle (214) configurée (274) de sorte à être insérée autour de l'un (212) de l'écrou et de la bague, la rondelle comprenant un moyen (272) d'emboîtement élastique avec l'autre (213) de la bague et de l'écrou dans une position d'installation de l'ensemble, de sorte à empêcher une rotation l'un par rapport à l'autre de la bague et de l'écrou.
