Abstract

Dispositif de freinage d’écrou (1) par imbrication, à haut couple de freinage et facilement assemblable et démontable, avec une rondelle (2) translatant sur la vis (3) et se plaçant sur la face supérieure de l’écrou (2). L’écrou (1) comporte des saillies (8) et la rondelle (2) des encoches (6) réparties régulièrement sur leurs périphéries. Ces encoches (6) et ces saillies (8) présentent chacune une face plane (9 ou 10) inclinée du même angle (13) avec la face d’appui de l’écrou (12). Lorsqu’après serrage complet, l’écrou est légèrement tourné dans le sens sénestrogyre, les saillies (8) viennent s’engager dans les encoches (6) jusqu’à ce que la rondelle (2) vienne porter sur l’écrou (1). Les faces inclinées (9 et 10) portant les unes sur les autres et l’imbrication des saillies (8) et des encoches (6) interdisent tout desserrage de l’écrou (1) ou dégagement par translation de la rondelle (2). Figure pour l’abrégé : Fig. 6
