Description
Die Erfindung betrifft eine Vorrichtung für den Massenausgleich bei durch Kurbeltrieb angetriebenen Maschinen, z. B. Kurbelpressen, Stanz- und Prägemaschinen, mit beidseitig der Kurbelwelle des Kurbeltriebes angeordneten Ausgleichsgewichten.The invention relates to a device for mass balancing machines driven by crank drives, e.g. B. crank presses, punching and embossing machines, with counterweights arranged on both sides of the crankshaft of the crank drive.
Es sind schon solche Vorrichtungen bekanntgeworden, bei denen die Ausgleichsgewichte einerseits an der Kurbelwelle und anderseits an Hilfswellen angeordnet sind, die mit derselben Winkelgeschwindigkeit wie die Kurbelwelle, jedoch in entgegengesetzter Richtung zu dieser rotieren. Bei diesen bekannten Ausgleichsvorrichtungen sind mehrere rotierende Ausgleichsgewichte vorhanden, deren Anordnung jedoch besonders bei Maschinen mit großen oszillierenden Massen verhältnismäßig umständlich ist und erhebliche Lagerreibung bewirkt. Bei einer Veränderung des Hubes des Hauptkurbeltriebes wird das rotierende Ausgleichsgewicht bzw. die Ausgleichswirkung nicht verändert, so daß kein vollständiger Ausgleich mehr vorhanden ist.Such devices have already become known in which the Balance weights arranged on the one hand on the crankshaft and on the other hand on auxiliary shafts are at the same angular velocity as the crankshaft, but in opposite directions Rotate towards this. In these known compensating devices are several rotating counterweights are available, but their arrangement is particularly important in machines with large oscillating masses is relatively cumbersome and considerable Bearing friction causes. When the stroke of the main crank drive is changed the rotating counterweight or the counterbalancing effect does not change, so that there is no longer a complete balance.
Die Erfindung bezweckt eine Vereinfachung einer solchen Massenausgleichsvorrichtung, indem sie keine rotierenden Ausgleichsgewichte aufweist und von einfachem platzsparendem Aufbau ist. Sie ist besonders für solche Maschinen, z. B. Kurbelpressen, Stanz- und Prägemaschinen geeignet, die große oszillierende Massen aufweisen und schnellaufend sind.The invention aims to simplify such a mass balancing device, by having no rotating counterweights and of simple space-saving Construction is. It is especially useful for such machines, e.g. B. crank presses, stamping and embossing machines are suitable, which have large oscillating masses and are fast running are.
Gemäß der Erfindung sind bei einer Vorrichtung für den Massenausgleich bei durch Kurbeltrieb angetriebenen Maschinen die Ausgleichsgewichte über ; im Maschinengehäuse gelagerte Doppelhebel und Lenker mit dem Kreuzkopf bzw. Kolben des Kurbeltriebes verbunden, so daß die Ausgleichsgewichte entgegengesetzt zum Maschinenhub hin- und herbewegt werden. Es sind hier also an Stelle von rotierenden Ausgleichsgewichten einfache hin- und herbewegliche Ausgleichsgewichte vorhanden, die über Doppelhebel und Lenker unmittelbar mit den oszillierenden Massen in Verbindung stehen. Die ganze Vorrichtung ist von einfachem Aufbau und bei einer Veränderung des Hubes des Hauptkurbeltriebes wird der Hub der Ausgleichsgewichte selbsttätig um den gleichen Betrag verändert, so daß stets ein vollständiger Massenausgleich vorhanden ist.According to the invention are in a device for mass balancing in machines driven by a crank drive, the counterweights over; in the machine housing mounted double lever and handlebar with the cross head or piston of the crank mechanism connected so that the counterweights back and forth opposite to the machine stroke be moved. So there are here instead of rotating counterweights simple floating counterweights available, which are operated via twin levers and handlebars are directly connected to the oscillating masses. The whole The device is of simple construction and when the stroke of the main crank drive is changed the stroke of the counterweights is automatically changed by the same amount, so that there is always a complete balance of masses.
Um ferner auch einen Ausgleich der rotierenden Massenkräfte zu erzielen, können die für den Ausgleich der oszillierenden Massen vorhandenen Ausgleichsgewichte über weitere im Maschinengehäuse gelagerte Doppelhebel und Lenker mit den Kurbelwellen so verbunden sein, daß sie auch quer bewegt werden. Es sind hier somit auch für den Ausgleich der rotierenden Massenkräfte keine rotierenden Ausgleichsgewichte erforderlich.In order to also achieve a balance of the rotating inertia forces, can use the balancing weights available for balancing the oscillating masses Via further double levers and control arms with the crankshafts mounted in the machine housing be connected in such a way that they can also be moved transversely. There are therefore also for the balancing of the rotating inertia forces no rotating counterweights necessary.
In der Zeichnung sind drei Ausführungsbeispiele des Erfindungsgegenstandes dargestellt. Es zeigt F i g. 1 einen Schnitt durch das erste Beispiel einer Massenausgleichsvorrichtung, F i g. 2 einen gleichen Schnitt durch das zweite Beispiel und F i g. 3 einen entsprechenden Schnitt durch das dritte Beispiel.The drawing shows three exemplary embodiments of the subject matter of the invention shown. It shows F i g. 1 shows a section through the first example of a mass balancing device, F i g. 2 shows the same section through the second example and FIG. 3 a corresponding Section through the third example.
Beim Beispiel nach F i g. 1 greift an einem Zapfen der Kurbelwelle 1 eine Kurbelstange 2 an, die andernends an den Kreuzkopf bzw. Kolben 3 angelenkt ist, der im Maschinengehäuse 4 in Hubrichtung verschiebbar geführt ist. Am Kolben 3 greifen zwei Lenker 5 an, die über gleicharmige Doppelhebel 6, die im Maschinengehäuse 4 gelagert sind, mit je einem Ausgleichsgewicht 7 verbunden sind. Die beiden Ausgleichsgewichte 7 befinden sich beidseitig der Kurbelwelle 1 quer zur Hubrichtung. Sie sind andernends über am Maschinengehäuse 4 angelenkte Führungslenker 8 festgelegt. Bei der Drehung der Kurbelwelle 1 werden die beiden Ausgleichsgewichte 7 in Hubrichtung, und zwar entgegengesetzt zum Maschinenhub bewegt, wodurch ein Ausgleich der oszillierenden Massen erhalten wird.In the example according to FIG. 1 engages a journal on the crankshaft 1 a connecting rod 2, which is hinged to the cross head or piston 3 at the other end is, which is guided in the machine housing 4 displaceably in the stroke direction. On the piston 3 attack two links 5, which have equal-armed double levers 6 in the machine housing 4 are stored, each connected to a counterweight 7. The two counterweights 7 are located on both sides of the crankshaft 1 transversely to the stroke direction. They are the other night fixed via guide links 8 articulated on the machine housing 4. When turning the crankshaft 1, the two balance weights 7 in the stroke direction, namely moves opposite to the machine stroke, compensating for the oscillating Masses is obtained.
Zum Beispiel nach F i g. 2 sind die Ausgleichsgewichte 7 andernends durch ein Gelenk 12 miteinander verbunden und damit in ihrer Lage festgelegt.For example, according to FIG. 2 are the counterweights 7 at the other end connected to one another by a joint 12 and thus fixed in their position.
Das Beispiel nach F i g. 3 unterscheidet sich vom Beispiel nach F i g. 1 dadurch, daß hier an Stelle der am Maschinengehäuse angelenkten Führungslenker 8 Lenker 9 vorhanden sind, welche an dem einen Hebelarm von Doppelhebeln 10 angreifen, deren andere längere Hebelarm über je einen Lenker 11 mit der Kurbelwelle 1 verbunden ist. Dadurch werden hier die Ausgleichsgewichte 7 außer in gleicher Weise wie beim ersten Beispiel in Hubrichtung auch noch quer zur Hubrichtung bewegt, und es werden hier somit auch die rotierenden Massenkräfte ausgeglichen.The example according to FIG. 3 differs from the example according to F. i g. 1 in that here instead of the guide arm hinged to the machine housing 8 handlebars 9 are present, which attack one lever arm of double levers 10, the other longer lever arm each connected to the crankshaft 1 via a link 11 is. As a result, the balance weights 7 are here except in the same way as in first example in the stroke direction also moved transversely to the stroke direction, and there are The rotating inertia forces are thus also balanced here.
Bei den beschriebenen Beispielen ist die Anordnung der Ausgleichsgewichte und deren Antrieb von der Kurbelwelle aus vollständig getrennt von dem nicht dargestellten Hauptkurbeltrieb der Maschine. Die Ausgleichsgewichte beeinflussen hier somit die Maschinengenauigkeit in keiner Weise.In the examples described, the arrangement of the counterweights is and their drive from the crankshaft completely separate from the one not shown Main crank drive of the machine. The counterweights thus influence the Machine accuracy in any way.
Bei Maschinen mit verstellbarem Hub des Hauptkurbeltriebes wird auch der Hub der Ausgleichsgewichte automatisch um den gleichen Betrag verstellt.In machines with adjustable stroke of the main crank drive, the stroke of the counterweights is automatically adjusted by the same amount.
