Abstract[English]
In manufacturing the jacks that its moving course is long, the pipes shafts are used with large diameter for prevention from shaft bending, and for prevent from not exiting lubricant from the shaft during operation, the head part of the shaft in the cylinder is blocked, and this case results in pump the moving lubricant in suitable mass with the shaft mass during jack operation, and with this method we do not block the head part of the shaft, but with a piston in the shaft as per the cylinder that was fixed we prevent from exciting lubricant from the shaft during movement.[French]
Dans la fabrication des vérins dont la course de déplacement est longue, les arbres des tubes sont utilisés avec un grand diamètre pour prévenir la flexion de l'arbre, et pour éviter que le lubrifiant ne sorte pas de l'arbre pendant le fonctionnement, la partie tête de l'arbre dans le vérin est bloquée, et cette situation conduit à pomper le lubrifiant mobile en une masse appropriée à la masse de l'arbre pendant le fonctionnement du vérin, et avec ce procédé on ne bloque pas la partie tête de l'arbre, mais avec un piston dans l'arbre comme avec le cylindre qui a été fixé, on empêche la sortie du lubrifiant de l'arbre pendant le mouvement.
