Title (EN) ROTATION-LOCKING SYSTEM FOR BUSHES IN CARBON-FIBRE FITTINGS
(ES) SISTEMA ANTI-ROTACIÓN PARA CASQUILLOS EN HERRAJES DE FIBRA DE CARBONO
(FR) SYSTÈME ANTI-ROTATION POUR DOUILLES DANS DES FERRURES EN FIBRE DE CARBONE
Abstract:
(EN) The invention relates to the design of aeronautical structures which, following the development of carbon-fibre components, requires the need for metal bushes to be installed on carbon-fibre fittings and, consequently, for systems that prevent the rotation of said bushes to be developed. The invention is essentially characterized in that it includes a main part (1) fastened to the respective bush, said fastening including means for preventing the relative rotation of the bush (2) and the associated main part (1), the latter also being provided with at least one lug (5) which clamps at least a side portion (6) of the fitting so as to fix same in position.
(ES) El ámbito del diseño de estructuras aeronáuticas, y dado el desarrollo de componentes en fibra de carbono, surge la necesidad de instalar casquillos metálicos sobre herrajes de fibra de carbono, y por tanto de desarrollar sistemas antigiro de dichos casquillos. Se caracteriza esencialmente porque cuenta con una pieza principal (1) vinculada al respectivo casquillo, vinculación que incluye medios para evitar el giro relativo entre el casquillo (2) y la propia pieza principal (1), a la vez que ésta cuenta con al menos una patilla (5) que abraza al menos una porción lateral (6) del herraje para su inmovilización.
(FR) Dans le cadre de la conception de structures aéronautiques et étant donné le développement des composants en fibre de carbone, il devient nécessaire de poser des douilles métalliques sur les ferrures en fibre de carbone et ainsi de développer des systèmes anti-rotation pour ces douilles. Le système selon l'invention se caractérise principalement en ce qu'il comprend une pièce principale (1) reliée à la douille respective, lequel raccord comprend un moyen permettant d'éviter la rotation relative entre la douille (2) et la pièce principale (1) elle même, laquelle comprend également au moins une petite patte (5) entourant au moins une portion latérale (6) de la ferrure pour permettre son immobilisation.
