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. 6Nut braking device (1) by nesting, with high braking torque and easily assembled and disassembled, with a washer (2) translating on the screw (3) and being placed on the upper face of the nut (2) . The nut (1) has projections (8) and the washer (2) notches (6) evenly distributed on their peripheries. These notches (6) and these projections (8) each have a flat face (9 or 10) inclined at the same angle (13) with the bearing face of the nut (12). When, after complete tightening, the nut is slightly turned in the antirotatory direction, the projections (8) come to engage in the notches (6) until the washer (2) comes to bear on the nut (1 ). The inclined faces (9 and 10) bearing on each other and the overlapping of the projections (8) and the notches (6) prevent any loosening of the nut (1) or disengagement by translation of the washer (2). Figure for the abstract: Fig. 6
