MECANISME CONSTITUE PAR LES ROULETTES A CHIFFRES D'UN MECANISME COMPTEUR, ACCOUPLEES ENTRE ELLES AU MOYEN D'UN PIGNON DE TRANSMISSION

摘要

The digit rolls of a counter a connected through transfer pinions in that pins extending axially from one roll towards another one engage a pinion once per revolution and the pinion turns the other roll by one step. The pins of the two rolls overlap axially with a slight radial clearance so that the gap between the rolls is just slightly larger than the length of either pin. The pins have semicircular, triangular, trapezoidal or rectangular cross-section.
