Abstract
(DE)
Die Erfindung betrifft eine Vorrichtung (20) zum aktiven Dämpfen von Schwingungen wenigstens eines Maschinenelements (18). Die Vorrichtung (20) weist zwei Dämpfungselemente (30, 32) auf, welche um jeweilige Drehachsen (22, 24) relativ zu dem Maschinenelement (18) drehbar sind und jeweils eine Unwucht (26, 28) aufweisen. Die Vorrichtung (20) umfasst auch eine Antriebseinrichtung (34), mittels welcher die Dämpfungselemente (30, 32) antreibbar und dadurch gegensinnig um die Drehachsen (22, 24) drehbar sind. Hierdurch ist eine in einer senkrecht zu den Drehachsen verlaufenden Ebene wirkende Kraft zum Dämpfen der Schwingungen erzeugbar. Außerdem umfasst die Vorrichtung (20) eine Stelleinrichtung (40), mittels welcher die Dämpfungselemente (30, 32) relativ zueinander phasenverstellbar sind, wodurch eine in der Ebene verlaufende Wirkrichtung der Kraft einstellbar ist.
(EN)
The invention relates to a device (20) for actively damping vibrations of at least one machine element (18). The device (20) has at least two damping elements (30, 32), which can be rotated relative to the machine element (18) about respective axes of rotation (22, 24) and have respective imbalances (26, 28). The device (20) also comprises a drive apparatus (34), by means of which the damping elements (30, 32) can be driven and thus can be rotated about the axes of rotation (22, 24) in opposite directions. A force acting in a plane running perpendicularly to the axes of rotation can thereby be produced in order to damp the vibrations. The device (20) also comprises an adjusting apparatus (40), by means of which the damping elements (30, 32) can be phase-adjusted relative to one another, whereby the direction of action of the force can be set, which direction of action runs in the plane.
(FR)
La présente invention concerne un dispositif (20) pour l'amortissement actif d'oscillations d'au moins un élément de machine (18). Le dispositif (20) présente deux éléments d'amortissement (30, 32), qui peuvent tourner autour d'axes de rotation respectifs (22, 24) par rapport à l'élément de machine (18) et qui présentent respectivement un balourd (26, 28). Le dispositif (20) comprend également un dispositif d'entraînement (34) au moyen duquel les éléments d'amortissement (30, 32) peuvent être entraînés et tournés en sens opposés autour des axes de rotation (22, 24). Une force agissant dans un plan s'étendant perpendiculairement aux axes de rotation peut ainsi être générée pour amortir les oscillations. En outre, le dispositif (20) présente un dispositif de réglage (40) à l'aide duquel les phases des éléments oscillants (30, 32) peuvent être réglées l'une par rapport à l'autre, ce qui permet de régler un sens d'action de la force s'étendant dans le plan.
