Abstract

L'invention concerne un dispositif pour le réglage du positionnement d'un appareil orientable comprenant, à l'interieur d'un carter, une roue dentée, montée tournante autour de son axe et supportant l'appareil à orienter, et une vis sans fin engrénant avec la roue dentée. La vis sans fin 18 traverse un passage 26, 28 du carter 10, surdimensionné par rapport à son diametre et est articulée par un point 30 de sa longueur dans ledit passage, de façon à pouvoir pivoter entre une position embrayée pour laquelle ses filets 17 sont en prise avec les dents de la roue dentée 12 et une position débrayée pour laquelle les dents sont dégagées de la roue, ledit dispositif comprenant également des moyens élastiques de poussée à rattrapage de jeu 46, 48 qui sollicitent la vis sans fin dans sa position d'embrayage et des moyens de débrayage 52. Application au réglage de l'orientation en azimut des appareils de visée.
