Abstract

L'invention est relative à un système vis-écrou destiné à résister à des efforts longitudinaux de sens déterminé, à un système vis-écrou débrayable et à un étau mettant en oeuvre ce système. Le système comporte une vis longitudinale et un écrou supportant respectivement des efforts longitudinaux antagonistes. Il est caractérisé en ce que le filet de la vis présente, dans le sens de l'effort longitudinal que doit subir cette dernière, une face inclinée en majeure partie dans le sens de cet effort par rapport à la direction longitudinale de la vis, dans le sens d'un éloignement par rapport à l'axe, et en ce que le filet de l'écrou presente, dans le sens de l'effort longitudinal que doit subir ce dernier, une face complémentaire inclinée dans le sens de cet effort par rapport à la direction longitudinale, dans le sens d'un rapprochement par rapport à l'axe. Application à la réalisation de systèmes auto-serrants.
