In der DE-EP 0 976 483 A2 ist ein Bearbeitungsaggregat offenbart, welches mit einem Riementrieb arbeitet.DE-EP 0 976 483 A2 describes a Processing unit disclosed, which works with a belt drive.
Aufgabe der vorliegenden Erfindung ist es, ein Bearbeitungsaggregat gattungsgemäßer Art zur Verfügung zu stellen, welches die aufgezeigten Nachteile des Standes der Technik nicht aufweist.Object of the present invention is to provide a processing unit of the generic type represent the disadvantages of the prior art does not have.
Diese Aufgabe wird mit einem Bearbeitungsaggregat gelöst, das die Merkmale des Anspruchs 1 aufweist.This task is done with a processing unit solved, having the features of claim 1.
Bearbeitungsaggregate der eingangs genannten Art sind seit mindestens 30 Jahren auf dem Markt. Noch wesentlich länger bekannt sind Reibradgetriebe. Es ist daher überraschend, dass es bisher unterblieben ist, den Stand der Technik durch die erfindungsgemäße Lösung zu bereichern. Reibradgetriebe sind von Hause aus spielfrei und geräuscharm. Des weiteren lassen sich mit ihnen sehr hohe Drehzahlen bei Übersetzung ins Schnelle erreichen. Derartig hohe Drehzahlen (20 000 U/min und mehr) sind bei Bearbeitungsaggregaten der hier angesprochenen Art wünschenswert. Des weiteren können Reibradgetriebe gleichzeitig die Funktion einer Überlastkupplung übernehmen.Processing units of the beginning species have been on the market for at least 30 years. Yet much longer Friction wheel transmissions are known. It is therefore surprising that it has so far been omitted is to the state of the art through the inventive solution enrich. Friction gearboxes are free of play and low in noise. Of they can also be used to translate very high speeds reach quickly. Such high speeds (20,000 rpm and more) are for processing units of the type mentioned here desirable. Furthermore, you can Friction gearbox simultaneously take over the function of an overload clutch.
Um auch bei einem nicht zu vermeidenden Verschleiß der Reibräder eine verlässliche Kraftübertragung zu erreichen, stehen die in Kontakt befindlichen Reibräder unter konstanter Normalkraft. Dies wird erfindungsgemäß dadurch erreicht, dass mindestens ein Reibrad eines Reibradsatzes schwimmend gelagert und durch sich an einem Widerlager abstützende Federmittel, z. B. ein Tellerfederpaket, zur Erzeugung einer konstanten Normalkraft beaufschlagt ist. Anstelle von Federmitteln können auch hydraulische Mittel zur Erzeugung einer konstanten Normalkraft zum Einsatz kommen.In order to avoid wear even when the friction wheels wear reliable power transmission the friction wheels in contact are under constant normal force. This is achieved according to the invention in that at least a friction wheel of a friction wheel set floating and by itself supporting on an abutment Spring means, e.g. B. a plate spring assembly to generate a constant Normal force is applied. Instead of spring means, hydraulic ones can also be used Means for generating a constant normal force are used.
In weiterer Ausgestaltung der Erfindung ist die Antriebsspindel, auf der das durch eine konstante Normalkraft beaufschlagte Reibrad sitzt, zur Realisierung der schwimmenden Lagerung in einem Doppel-Schrägkugellager gelagert.In a further embodiment of the invention is the drive spindle on which this is due to a constant normal force acted friction wheel sits, to realize the floating storage in a double angular contact ball bearing stored.
Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels näher erläutert. Die dazugehörige Zeichnung zeigt eine Schnittdarstellung eines Reibradwinkelfräskopf-Aggregates (nachfolgend abkürzend Aggregat genannt).The invention is illustrated below of an embodiment explained in more detail. The associated Drawing shows a sectional view of a friction wheel angle milling head unit (abbreviated below Called aggregate).
