Abstract

La présente invention concerne un engrenage de décélération et une serrure de porte numérique l'utilisant. L'engrenage de décélération selon la présente invention comporte : un engrenage d'entraînement qui tourne autour d'un axe de rotation tournant par un moteur et en prise avec un engrenage mené afin de pouvoir faire tourner l'engrenage mené par une force de rotation par le moteur ; et un moyen de transmission de puissance qui est agencé entre l'axe de rotation et l'engrenage d'entraînement à des fins de transmission de puissance entre l'axe de rotation et l'engrenage d'entraînement, de sorte que le moteur et l'engrenage d'entraînement peuvent tourner ensemble et qu'une force de rotation inverse est transférée à l'engrenage mené alors que l'axe de rotation et l'engrenage d'entraînement tournent ensemble dans une direction en réponse à un signal électrique par le moteur, la force de rotation inverse faisant tourner l'engrenage d'entraînement dans l'autre direction, l'axe de rotation pouvant ainsi continuer à tourner dans une direction sans être forcé de tourner dans l'autre direction dans le cas où l'engrenage d'entraînement tourne dans l'autre direction.
