Abstract

Le montant 2 comporte une douille de réglage 4 vissée sur deux éléments 12, 14 filetés à contre-sens, et un dispositif de blocage comprenant un manchon d'arrêt 26 disposé de façon à pouvoir se déplacer dans le sens de la longueur du montant porteur 2, et qui peut être repoussé dans le sens de l'axe vers la position de déblocage, contre l'action d'un ressort 36 agissant dans le sens de la longueur du montant porteur, ceci à partir d'une position de blocage dans laquelle la douille de réglage 4 est reliée, de façon à empêcher toute rotation, à l'un des éléments filetés 12. L'invention peut être utilisée comme tringle de commande rotative d'un rotor d'hélicoptère.The upright 2 comprises an adjustment sleeve 4 screwed onto two elements 12, 14 threaded against the direction, and a locking device comprising a stop sleeve 26 arranged so as to be able to move in the direction of the length of the supporting upright 2, and which can be pushed in the direction of the axis towards the unlocking position, against the action of a spring 36 acting in the direction of the length of the support post, this from a locking position in in which the adjustment sleeve 4 is connected, so as to prevent any rotation, to one of the threaded elements 12. The invention can be used as a rotary control rod of a helicopter rotor.
