Abstract

L'invention concerne un générateurs de vibrations pour appareils de compactage du sol, par exemple pour une plaque vibrante. Ce générateur de vibrations présente deux arbres à balourd (1, 2) parallèles ou coaxiaux, pouvant être entraînés dans des sens opposés, à la même vitesse de rotation, et portant chacun au moins une masselotte (3, 4). La position de phase des masselottes (3, 4) peut être réglée par un dispositif de réglage de phase de sorte que les composantes verticales des forces centrifuges (5, 6) générées par les masselottes (3, 4) s'annulent dans chaque position de rotation. Dans le même temps, les composantes horizontales des forces centrifuges (5, 6) s'additionnent en étant dirigées dans le même sens. Cette position de phase empêche la plaque vibrante de produire des vibrations verticales dans le sol à compacter, lorsqu'elle est stationnaire, mais permet d'introduire des contraintes de cisaillement dans le sol, de préférence au niveau d'une surface asphaltée, par l'intermédiaire d'une plaque de contact avec le sol, pour colmater des fissures et des pores par compactage.
