Abstract

Sistema anti-rotación para bulones en orejetas de estructuras aeronáuticas. En el ámbito del diseño de estructuras aeronáuticas, existen numerosos casos donde es necesario el uso de bulones y casquillos para poder garantizar uniones entre elementos. Dado que para esas uniones con bulones se utilizan además tuercas de bloqueo, es necesario impedir la rotación de unos elementos respecto de los otros elementos para garantizar la funcionalidad correcta. Para ello el sistema anti-rotación de la invención asegura que se cumplan todos los requerimientos de seguridad para el montaje. Se caracteriza porque comprende un soporte anti-rotación (3) asociado al correspondiente bulón (5), a la vez que se inmoviliza en correspondencia con una de las orejetas, bloqueándose el giro de tal bulón a través de su cabeza en combinación con unos elementos que forman parte de tal soporte anti-rotación (3).Anti-rotation system for bolts on lugs of aeronautical structures. In the field of aeronautical structure design, there are numerous cases where it is necessary to use bolts and bushings to be able to guarantee joints between elements. Since locking nuts are also used for these bolt joints, it is necessary to prevent the rotation of some elements with respect to the other elements to ensure proper functionality. For this, the anti-rotation system of the invention ensures that all safety requirements for assembly are met. It is characterized in that it comprises an anti-rotation support (3) associated with the corresponding bolt (5), at the same time as it is immobilized in correspondence with one of the lugs, blocking the rotation of such bolt through its head in combination with elements which are part of such anti-rotation support (3).
