DEUTSCHESGERMAN
Es ist bekannt, daß die Laufruhe von scheibenförmigen rotierenden Werkzeugen, z. B. von Schleifscheiben, Polierscheiben, Schmirgelscheiben od. dgl., und damit die Belastung der Lager sowie die Qualität der mit diesen Scheiben durchzuführenden Arbeiten von dem exakten Auswuchten der Werkzeuge abhängig ist. Aus diesem Grund werden z. B. Schleifscheiben vom Herstellerwerk ausgewuchtet, d. h., die Lieferunwucht wird beseitigt. Durch die Abnutzung der Werkzeuge treten jedoch neue Unwuchten, d. h. die Betriebsunwuchten, auf, die bei den hohen Drehzahlen _zu einer erheblichen Belastung und Abnutzung der Hauptlager der Schleifmaschine, verbunden mit einem nicht unerheblichen Energieverschleiß, führen. Wenn an einer Schleifscheibe beim Umlauf Unwuchtkräftepaare auftreten, zeigt diese im Rahmen ihres Lagerspieles ein Flattern, welches das Arbeiten mit der Schleifscheibe beeinträchtigt.It is known that the smoothness of disc-shaped rotating tools, e.g. B. of grinding wheels, Polishing discs, emery discs or the like, and thus the load on the bearings and the quality the work to be carried out with these disks depends on the exact balancing of the tools is. For this reason z. B. grinding wheels balanced by the manufacturer, d. h., the Delivery imbalance is eliminated. However, as the tools wear out, new imbalances occur, i. H. the operational imbalances, which at the high speeds cause considerable stress and wear the main bearings of the grinding machine, combined with a not inconsiderable amount of energy wear. If pairs of imbalance forces occur on a grinding wheel during rotation, this shows within the scope of its Bearing play a flutter, which affects working with the grinding wheel.
Zum Einspannen der Schleifscheiben werden unter anderem auf den beiden Stirnseiten derselben angeordnete Flansche verwendet, in denen eine Ringnut vorgesehen ist. Diese Ringnut dient zur Aufnahme von Ausgleichsgewichten, welche der Behebung der vor der Inbetriebnahme der Schleifscheibe bereits festgestellten Unwucht dienen. Die während des Betriebes durch Abnutzung der Schleifscheibe erneut auftretende Betriebsunwucht ist bisher durch Verschieben der ursprünglich eingesetzten Gewichte beseitigt worden. Dies ist jedoch ziemlich schwierig, da die zum Beheben der Lieferunwucht dienenden verhältnismäßig großen Ausgleichsgewichte zum Ausgleich der nachträglich sich ergebenden sogenannten Betriebsunwucht zu grob sind. Vor allem aber führt das Verschieben eines Gewichtes an die neue Ausgleichsstelle dazu, daß es an der Stelle, an der es sich bisher befand, an Gewicht fehlt. Dies hat zwangläufig zur Folge, daß längere Zeit herumprobiert werden muß, bis das Gewicht an der richtigen Stelle sitzt.To clamp the grinding wheels, among other things, they are arranged on the two end faces Flanges used in which an annular groove is provided. This ring groove is used to accommodate Balancing weights, which the remedy of the already determined before the grinding wheel was put into operation Serve imbalance. The one that occurs again during operation due to wear and tear on the grinding wheel Operational imbalance has so far been eliminated by shifting the weights originally used been. However, this is quite difficult because the ones used to correct the delivery imbalance are relatively difficult large counterweights are too coarse to compensate for the so-called operational imbalance that subsequently occurs. Above all, however, the shifting leads a weight to the new compensation point so that it is at the point where it was previously, lacks weight. This inevitably means that you have to try things out for a long time, until the weight is in the right place.
Es wurde auch bereits vorgeschlagen, Hohlringe mit Kammern zu verwenden, in die insbesondere auch zum Ausgleich der Betriebsunwucht Bleikugeln eingelegt werden. Derartige Hohlringe sind jedoch in der Herstellung verhältnismäßig kompliziert und kostspielig. Außerdem dürften die eingelegten Bleikugeln sich während des Betriebes verhältnismäßig rasch abreiben. Aus diesen Gründen haben diese Anordnungen bisher in der Praxis keine weitere Verbreitung gefunden. Es wäre denkbar — und dies wird mit Rücksicht auf die vorstehenden Ausführungen zum Stand der Technik als potentieller Stand der Technik erachtet —, die Betriebsunwucht durch Einsetzen kleiner Zusatzgewichte in die übliche Flanschnut zu beseitigen. Dann wäre allerdings deren Feineinstellung durch die großen Gewichte behindert.It has also already been proposed to use hollow rings with chambers in which in particular lead balls are inserted to compensate for the operational imbalance. Such hollow rings are, however, in the Relatively complex and expensive to manufacture. In addition, the inserted lead balls should wear off relatively quickly during operation. For these reasons, these arrangements so far found no further distribution in practice. It would be conceivable - and this will come with Consideration of the above statements on the state of the art as potential state of the art considers - to reduce the operational imbalance by inserting small additional weights in the usual flange groove remove. Then, however, their fine adjustment would be hindered by the large weights.

Gemäß der Erfindung wird nun eine Auswuchteinrichtung der in Rede stehenden Art vorgeschlagen, bei der mindestens einer der beiden Flansche neben der üblichen Ringnut eine zweite konzentrische sowie hinsichtlich Durchmesser und Querschnitt kleinere Ringnut aufweist, in der mindestens zwei zum Ausgleich der periodisch entstehenden Betriebsunwucht bestimmte Zusatzgewichte verschiebbar befestigt sind.According to the invention, a balancing device of the type in question is now proposed at the at least one of the two flanges in addition to the usual annular groove a second concentric and with respect to Has diameter and cross-section smaller annular groove, in which at least two to compensate the periodically occurring operational unbalance certain additional weights are attached to be displaceable.
Gemäß einer bevorzugten Ausführungsform des Gegenstandes der Erfindung verhält sich der Querschnitt
der kleineren Ringnut zu dem der größeren Ringnut wie 1 :2 bis 1 :10, vorzugsweise wie 1 :3 bis 1 :5.
Bei der Auswuchteinrichtung gemäß der Erfindung wird also die Lieferunwucht der Schleifscheibe wie
bisher durch entsprechende Anordnung größerer Ausgleichsgewichte in der äußeren, breiteren Ringnut beseitigt.
Die Betriebsunwuchten werden periodisch durch Verschieben der kleineren Ausgleichsgewichte
in der erfindungsgemäßen inneren Ringnut, die einen kleineren Querschnitt aufweist, ausgeglichen. Es ist
nicht mehr erforderlich, daß die größeren Ausgleichsgewichte bei jedem Nachwuchten verschoben werden.
Die kleineren Ausgleichsgewichte können unabhängig von den größeren Ausgleichsgewichten über, den gesamten
Umfang der inneren Ringnut herum verschoben werden, ohne daß sie dabei von den größeren
Ausgleichsgewichten behindert werden.According to a preferred embodiment of the subject matter of the invention, the ratio of the cross section of the smaller annular groove to that of the larger annular groove is from 1: 2 to 1:10, preferably from 1: 3 to 1: 5.
In the balancing device according to the invention, the delivery unbalance of the grinding wheel is thus eliminated, as before, by a corresponding arrangement of larger counterweights in the outer, wider annular groove. The operational imbalances are periodically compensated for by moving the smaller counterweights in the inner annular groove according to the invention, which has a smaller cross section. It is no longer necessary for the larger counterweights to be shifted with each rebalancing. The smaller counterweights can be moved independently of the larger counterweights over the entire circumference of the inner ring groove without being hindered by the larger counterweights.
