Abstract

L'invention concerne la mécanique. Elle concerne notamment un dispositif de transmission comprenant deux roues montées sur des axes parallèles ou concourants et coopérant entre elles par leur jante, caractérisé en ce que la jante de l'une des roues est constituée par une épaisseur de matière souple et élastique, tandis que la jante de l'autre roue comporte des saillies régulièrement espacées et en forme de calotte sphérique. L'invention s'applique, en particulier, aux variateurs de vitesse.
