Abstract

L'invention concerne un mécanisme d'entraînement destiné à produire un mouvement linéaire. Le mécanisme comprend deux moteurs pas-à-pas 11, 12 respectivement accouplés à des vis sans fin 7, 17, une roue tangente 19 en prise avec les vis sans fin 16, 17 et montée sur un chariot 22 de façon à assurer son mouvement linéaire, le mouvement linéaire de la roue tangente produisant le mouvement de sortie nécessaire, ce mouvement étant fonction de la rotation de l'un ou l'autre, ou bien des deux moteurs Il, 12. Application à des appareils de commande hydraulique.A drive mechanism for producing linear motion is disclosed. The mechanism comprises two stepper motors 11, 12 respectively coupled to worm screws 7, 17, a tangent wheel 19 engaged with worm screws 16, 17 and mounted on a carriage 22 so as to ensure its movement. linear, the linear movement of the tangent wheel producing the necessary output movement, this movement being a function of the rotation of one or the other, or of the two motors II, 12. Application to hydraulic control devices.
