Title (EN) NUT LOCKING DEVICE AND ASSEMBLY FOR MOUNTING SAME
(FR) DISPOSITIF DE BLOCAGE D'ÉCROU ET ENSEMBLE DE MONTAGE ASSOCIÉ
Abstract:
(EN) The invention relates to a locking device (300) comprising: a shaft (24) comprising a first thread (22); and a nut (12) and a ring (13) to be assembled on the shaft; the nut comprising a first inner thread (18) defining a first radial clearance with the first thread of the shaft; the nut further comprising a second inner thread (20) in the opposite direction to the first inner thread, the ring (13) comprising a second thread (40) defining a second radial clearance with the second inner thread of the nut; the ring comprising a third inner thread (38) defining a third radial clearance with the first thread of the shaft. The inner threads and the first and second threads have an identical and constant thread pitch; and each of the second and third radial clearances is greater than the first radial clearance.
(FR) L'invention concerne un dispositif de blocage (300), comportant : un arbre (24) comprenant un premier filetage (22); et un écrou (12) et une bague (13) destinés à être assemblés sur l'arbre; l'écrou comprenant un premier taraudage (18) définissant un premier jeu radial avec le premier filetage de l'arbre; l'écrou comprenant en outre un deuxième taraudage (20) de sens opposé au premier taraudage, la bague (13) comportant un deuxième filetage (40) définissant un deuxième jeu radial avec le deuxième taraudage de l'écrou; ladite bague comportant un troisième taraudage (38) définissant un troisième jeu radial avec le premier filetage de l'arbre. Les taraudages et les premier et deuxième filetages présentent un pas de filet identique et constant; et chacun des deuxième et troisième jeux radiaux est supérieur au premier jeu radial.
