Patent

CA 2282712

A threaded fastener (32) including a nut (10) and a bolt (30) with the nut (10) including a ring section (14) and a nut section (12) with the nut section (12) having a main body portion (16) and a neck portion (18) with the neck portion (18) adapted to be moved into the ring section (14) and to be moved radially inwardly such that the threads in the neck portion (18) are moved into compressive engagement with the engaged threads of the bolt (30) to provide prevailing torque structure resisting loosening of the nut member (10) from the bolt (30).

Cette invention concerne une fixation filetée (32) qui comprend un écrou (10) et un boulon (30). L'écrou (10) comprend une section annulaire (14) ainsi qu'une section écrou (12) qui possède une partie corps principal (16) et une partie collet (18). La partie collet (18) est conçue pour se déplacer dans la section annulaire (14), radialement et vers l'intérieur de sorte que le filetage de la partie collet (18) entre en contact sous pression contre le filetage du boulon (30). Ce système offre ainsi une structure de couple dominant qui empêche l'écrou (10) de se desserrer du boulon (30).
