Abstract

Procédé pour régler l'angle de déviation d'un dispositif vibrant tel qu'un tamis ou un dispositif d'alimentation du type qui possède un moyen d'entraînement avec des moyens en déséquilibre autour de deux arbres qui sont mutuellement parallèles. On entraîne les deux moyens en déséquilibre, qui sont de dimensions différentes, par des moteurs individuels et l'on dispose leurs arbres par rapport au centre de gravité du dispositif de telle manière que le centre de gravité se trouve sur un cercle apollonien par rapport aux deux arbres, déterminé de telle façon que le rapport des distances du centre de gravité aux axes de rotation soit inversement proportionnel aux produits des poids en déséquilibre des moyens respectifs en déséquilibre par leur distance moyenne à l'axe respectif de rotation, l'angle de déviation étant affecté par le changement de puissance de l'un des moteurs par rapport à celle de l'autre.A method of adjusting the angle of deflection of a vibrating device such as a screen or a feeder of the type which has a drive means with means unbalanced around two shafts which are mutually parallel. The two means are driven in imbalance, which are of different dimensions, by individual motors and their shafts are placed in relation to the center of gravity of the device in such a way that the center of gravity is on an Apollonian circle with respect to the two shafts, determined in such a way that the ratio of the distances from the center of gravity to the axes of rotation is inversely proportional to the products of the unbalanced weights of the respective unbalanced means by their average distance to the respective axis of rotation, the angle of deviation being affected by the change in power of one motor relative to that of the other.
