Abstract

Réducteur de montre-bracelet électronique à moteur pas-à-pas et aiguille de seconde centrale comprenant trois arbres coaxiaux de sortie tournant à des vitesses différentes, reliés à l'arbre 2 du moteur pas-à-pas 3 par des couples dentés. L'arbre 12 des minutes tourne dans un palier emmanché dans un trou de la platine 26 de la montre et dont une partie dépasse côté pont 23 de la montre, Les déplacements axiaux de l'arbre 12 sont limités dans un sens par la tranche du palier support 28 et, dans l'autre, par la face du pignon 13, serré sur l'arbre 12. Application à l'industrie horlogère.
