Abstract

Un mécanisme dengrenage est décrit, lequel comprend une cassette, un ressort, un moyeu et un contrepoids dans lequel le ressort est placé pour appliquer une force sur la cassette, et dans lequel le contrepoids est couplé à la cassette de sorte que, sous la rotation du moyeu, une accélération centripète agit sur le contrepoids de manière à appliquer une force à la cassette, opposée en direction à la force du ressort, suffisante pour à vaincre au moins une partie de la force appliquée à la cassette par le ressort de manière à déplacer la cassette dans une direction opposée à la direction de la force du ressort.
