Abstract

La présente invention concerne une unité de transmission de force d'entraînement conçue de manière à ce qu'un second corps rotatif placé sur le côté périphérique externe d'un premier corps rotatif soit mis en rotation autour d'un axe de révolution par une force d'entraînement transmise au second corps rotatif par la rotation du premier corps rotatif. Dans un état dans lequel une force de pression agit sur un second rouleau du second corps rotatif à partir d'un premier rouleau du premier corps rotatif, l'angle obtus formé par une première ligne de référence, qui relie un premier axe de rotation et un second axe de rotation, et une seconde ligne de référence, qui relie l'axe de révolution et le point d'action de la force de pression sur le second rouleau, est supérieur ou égal à 112º et inférieur ou égal à 120 °.
