Abstract

Un dispositif antichoc pour instruments de mesure à cadrans dont le mécanisme multiplicateur de transmission comprend un rattrapage de jeu par précontrainte élastique de son train de roues d'engrenage. Ce dispositif a ceci de particulier qu'un premier élément denté comporte deux doigts d'entraînement disposés à un certain écart radial l'un de l'autre, qu'un deuxième élément denté coaxial au premier comporte un seul doigt d'entraînement situé entre les deux doigts précités, et qu'un ressort à boudin dont l'enroulement des spires est contraint, est intercalé entre les deux dits éléments dentés et a son axe d'enroulement sensiblement parallèle à l'axe commun de rotation des deux éléments dentés et ses deux extrémités repliées et disposées radialement en appui contre les deux doigts d'entraînement du premier élément denté de part et d'autre de ceux-ci, le doigt d'entraînement du deuxième élément denté étant ainsi lié aux deux doigts du premier élément denté par emprisonnement élastique entre les extrémités du ressort à boudin.
