Abstract

Dispositif de compensation d'un jeu mécanique sur un positionneur d'antenne comprenant une couronne C1 et un engrenage C2, permettant la transmission du mouvement d'un moteur porté sur une plaque interface à l'antenne, ladite plaque interface étant reliée à un berceau caractérisé en ce que le dispositif de compensation est composé d'un tube (62) ayant un intérieur taraudé (63), un ressort (61) monté dans le tube, le ressort étant en appui sur un premier côté (61a) sur un piston (64) coulissant dans ledit tube et sur un deuxième côté (61b) sur une vis de précharge (65), le ressort étant préchargé afin d'assurer une pression sensiblement constante sur le berceau quelle que soit la position de l'engrenage sur la couronne.Device for compensating a mechanical play on an antenna positioner comprising a ring C1 and a gear C2, allowing the transmission of the movement of a motor carried on an interface plate to the antenna, said interface plate being connected to a cradle characterized in that the compensation device is composed of a tube (62) having a threaded interior (63), a spring (61) mounted in the tube, the spring being supported on a first side (61a) on a piston (64) sliding in said tube and on a second side (61b) on a preload screw (65), the spring being preloaded to ensure a substantially constant pressure on the cradle regardless of the position of the gear on the crowned.
