Title
(EN) NUT FOR A MOMENT SCREW
(FR) ECROU POUR VIS À COUPLE
Abstract
(EN)
The present invention relates to a nut (6) for a moment screw, comprising an upper torsion member (1), a lower clamping member (2) of the same material with the torsion member (1). A weakening groove (3) is between the torsion member and the clamping member, the weakening part (3) being dimensioned so as to establish a fraction point between the torsion member and the clamping member as a given torque occurs between the torsion member and the clamping member. The lower clamping member (2) has its thread (4) continue across the fraction point (3) of the nut (6) to a bottom edge or bottom part of the torsion member (1).
(FR)
La présente invention concerne un écrou (6) pour vis à couple, comprenant un élément de torsion supérieur (1), un élément de serrage inférieur (2) composé du même matériau que l'élément de torsion (1). Une rainure d'affaiblissement (3) se situe entre l'élément de torsion et l'élément de serrage, la partie d'affaiblissement (3) étant dimensionnée de manière à établir un point de fraction entre l'élément de torsion et l'élément de serrage lorsqu'un couple donné se produit entre l'élément de torsion et l'élément de serrage. Le filet (4) de l'élément de serrage inférieur (2) se poursuit en travers du point de fraction (3) de l'écrou (6) en direction d'un bord inférieur ou d'une partie inférieure de l'élément de torsion (1).
