Patent

CA 2241672

A vibration-tolerant torque limiting fastening lug whereupon tightening of the set-screw produces a parasitic torque at the thread plane defining the set-screw/housing interface. The resulting parasitic torque acts in opposite direction to the installation torque such that the actual torque below the thread plane is less than the installation torque. As a result, the tensile force experienced by the set-screw and which acts against the housing of the lug is reduced.

Écrou de fixation limiteur de couple tolérant les vibrations. Le serrage de la vis de blocage produit un couple parasite au plan de filetage qui définit l'interface vis de blocage/logement. Le couple parasite résultant agit en sens opposé au couple de pose, de sorte que le couple effectif sous le plan de filetage est inférieur au couple de pose. Il en résulte que la force de traction à laquelle est soumise la vis de blocage et qui agit contre le logement de l'écrou s'en trouve réduite.
