Title (EN) GEAR-DRIVEN BALANCE SHAFT APPARATUS WITH BACKLASH CONTROL
(FR) APPAREIL A ARBRE DE COMPENSATION ENTRAINE PAR ENGRENAGE A COMMANDE DE JEU D'ENGRENEMENT
Abstract:
(EN) An apparatus for controlling backlash comprising an intermediate gear capable of adjustable meshed engagement between a first driving gear and a second driven gear, and a body rotatably supporting the intermediate gear and capable of movement in a direction that reduces the center distance between the intermediate gear and either the first gear, the second gear, or both. The movement of the body utilizes both a resilient urging and a hysteretic damping to supply appropriately light resilient biasing while being fortified against rapid retraction or repulsion.
(FR) L'invention concerne un appareil destiné à commander un jeu d'engrènement comprenant un engrenage intermédiaire capable de régler un pignon maillé entre un premier engrenage de commande et un second engrenage entraîné, et un corps supportant de façon rotative l'engrenage intermédiaire et permettant le mouvement dans un sens qui réduit la distance centrale entre l'engrenage intermédiaire et soit le premier engrenage, soit le second engrenage ou les deux. Le mouvement du corps utilise à la fois la sollicitation élastique et l'amortissement par hystérèse afin de fournir une sollicitation élastique légère, tout en étant fortifié contre la répulsion ou la rétraction rapide.
