Abstract

L'invention concerne un dispositif pour effectuer une mesure électromécanique du jeu axial d'éléments de construction rotatifs, comportant un carter muni d'un corps tournant approchant et éloignant un palpeur de l'objet à mesurer. Ce dispositif est caractérisé en ce que le corps tournant est constitué par l'arbre prolongé du moteur d'entraînement, l'extrémité de cet arbre voisine de l'objet comportant un détecteur à excentrique, un codeur d'angle etant prévu pour définir la position de zéro et déterminer les variations de distance, l'abaissement de la résistance de contact produisant un signal mettant en mémoire la valeur indiquée et ramenant l'arbre au zéro. L'invention est applicable notamment aux éléments de turbomachines
