Die vorliegende Erfindung betrifft einen Dämpfer zur Bekämpfung der Drehschwingungen von Wellen, bei denen in dem an der Kurbelwange angeordneten Gegengewicht Zusatzmassen pendelnd vorgesehen sind. Die Abstimmung solcher Dämpfer kann zwar rechnerisch erfolgen, bei der Ausführung ergeben sich jedoch Abweichungen, die teils in der Herstellung, teils in den schwer erfaßbaren Betriebsverhältnissen begründet sind. Die Erfindung vermeidet diesen Nachteil dadurch, daß die Dämpfungsmassen, die lose rollend angeordnet sind, mit symmetrisch zu ihrem Schwerpunkt verstellbaren Zusatzmassen versehen sind. Durch Veränderung des Trägheitsmomentes ist somit eine gleichmäßige Änderungsmöglichkeit zur Abstimmung in geringen Grenzen geschaffen, ohne daß dadurch der Massenausgleich des Gegengewichtes gestört wird.The present invention relates to a damper for combating torsional vibrations of shafts with additional masses in the counterweight arranged on the crank web are provided pendulously. The tuning of such dampers can are done arithmetically, but there are deviations during execution, some of which are justified in the production, partly in the difficult to determine operating conditions. The invention avoids this disadvantage in that the damping masses are loose are arranged in a rolling manner, with additional masses that can be adjusted symmetrically to their center of gravity are provided. By changing the moment of inertia it is thus a uniform Possibility of changing the vote created within small limits, without thereby the mass balance of the counterweight is disturbed. Zwei Ausführungen der Erfindung sind auf der Zeichnung beispielsweise dargestellt. Abb. ι zeigt einen Ringkörper als pendelnde Dämpfungsmässe,Two embodiments of the invention are shown in the drawing, for example. Fig. Ι shows an annular body as a pendulous damping measure, Abb. 2 eine Rolle als Dämpfgungsmasse.Fig. 2 a role as a damping mass. In einer Aussparung der an der Kurbelwange ι einer Kurbelwelle angeordneten Schwungmasse 2 ist eine ringförmige Masse 3 an einem Bolzen 4 aufgehängt. Der Bolzen 4 ist parallel zur Kurbelachse im Gewicht 2 befestigt, so daß der Ringkörper 3 in der Drehebene pendeln kann. Der Ringkörper 3 ist mit einem auf seinem Durchmesser liegenden Steg 5 versehen, auf dem zwei Zusatzmassen 6 verschiebbar geführt sind. Die Zusatzmassen 6 sind symmetrisch angeordnet und durch eine mit entgegengesetzten Gewindegängen gleicher Steigung versehene Spindel 7 verbunden. Die Spindel 7 ist in der Mitte des Steges gelagert, und durch Verdrehen derselben wird eine gleiche Verschiebung der Zusatzmassen 6 erreicht.In a recess which is arranged on the crank web ι of a crankshaft Inertia 2, an annular mass 3 is suspended from a bolt 4. The bolt 4 is attached parallel to the crank axis in the weight 2, so that the ring body 3 in the Rotation plane can swing. The ring body 3 is with a lying on its diameter Provided web 5, on which two additional masses 6 are displaceably guided. the Additional masses 6 are arranged symmetrically and by one with opposite threads the same pitch provided spindle 7 connected. The spindle 7 is in the Mounted in the middle of the web, and by turning it an equal displacement is achieved the additional masses 6 reached. Bei Verwendung eines zylinderförmigen Rollkörpers 8 gemäß Abb. 2 können die Zusatzmassen 6 entsprechend in einer Bohrung 9 verstellbar angeordnet werden.When using a cylindrical roller body 8 according to Fig. 2, the additional masses 6 can be arranged in a correspondingly adjustable manner in a bore 9.
