Abstract
Description
Späneabstreifer für Schälräder an Wälzschälmaschinen Die Erfindung betrifft einen Späneabstreifer für Schälräder an Wälzschälmaschinen, Beim Wälzschälen haften oft Späne durch Verschweißen auf den Spanflächen des schneidradförmigen Schälrades. Diese Späne gelangen dann beim nächsten Umlauf des Schälrades zwischen die Zähne von Schälrad und Werkstück. Sie verursachen dabei starken Verschleiß und eventuell Ausbrüche an den Schneidkanten der Schälradzähne beziehungsweise unsaubere Oberflächen der bearbeiteten Werkstückzähne. Chip scraper for peeling wheels on power skiving machines The invention relates to a chip scraper for skiving wheels on skiving machines, when skiving Chips often adhere to the rake faces of the cutting wheel-shaped peeling wheel due to welding. These chips then get between the teeth the next time the peeling wheel rotates of peeling wheel and workpiece. They cause heavy wear and tear and possibly Chipping on the cutting edges of the peeling wheel teeth or unclean surfaces of the machined workpiece teeth.
Bisher wurden als Späneabstreifer für Schälräder feststehende Entgratmeißel oder feststehende beziehungsweise rotierende Bürsten verwendet, Entgratmeißel sind jedoch für treppenförmig angeschliffene Schälräder nicht geeignet, und Bürsten streifen oft festhaftende Späne nicht ab. Außerdem verschleißen Bürsten sehr schnell und werden dadurch unbrauchbar. Diese Mittel führten nicht zu einem befriedigenden Erfolg.So far, fixed deburring chisels have been used as chip scrapers for peeling wheels or fixed or rotating brushes are used, deburring chisels are however, not suitable for stepped peeling wheels, and brushes will rub often sticking chips do not come off. In addition, brushes wear out very quickly and thereby become unusable. These means did not lead to a satisfactory result.
Der Erfindung liegt die Aufgabe zugrunde, die aufgezeigten Nachteile der bekannten Mittel zum Abstreifen der an den Schneidkanten der Schälradzähne haftenden Späne zu vermeiden, um an den Schälradzähnen übermäßigen Verschleiß und Ausbrüche zu verhindern und eine bessere Oberflächengüte der Werkstückzähne zu erzielen.The invention is based on the stated disadvantages the known means for stripping off those adhering to the cutting edges of the peeling wheel teeth Avoid chips, excessive wear and chipping on the peeling wheel teeth to prevent and to achieve a better surface quality of the workpiece teeth.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß Abstreifelemente geeigneter Form streifend oder in geringem Abstand über die Spanflächen der einzelnen Schälradzähne bewegt werden und dabei anhaftende Späne abstreifen0 Diese Abstreifelemente sind auf einem Grundkörper fixiert oder mit diesem aus einem Stück hergestellt. Dieser Späneabstreifer wird über geeignete Mittel synchron oder quasisynchron zum Umlauf des Schälrades angetrieben. Dies kann beispielsweise dadurch geschehen, daß der Grundkörper ein Stirnrad ist, das laufend im Eingriff mit dem arbeitenden Schälrad steht0 Es ist auch möglich, die Drehung über ein Getriebe von der Drehung der Schälradspindel abzuleiten oder einen getrennten elektrischen Antrieb - zum Beispiel durch einen Schrittmotor - zu verwenden, der von irgendeiner Stelle des Getriebezuges der Wälzschälmaschine gesteuert wird.According to the invention, this object is achieved in that stripping elements in a suitable shape by brushing or at a small distance over the rake faces of the individual Peeling wheel teeth are moved and scraping off adhering chips 0 These scraper elements are fixed on a base body or made in one piece with it. This chip scraper is synchronized or quasi-synchronous to the Rotation of the peeling wheel driven. This can be done, for example, in that the main body is a spur gear that is continuously in engagement with the working peeling gear stands0 It is too possible the rotation via a gear from the Derive rotation of the peeling wheel spindle or a separate electric drive - for example by a stepper motor - to be used by some point the gear train of the skiving machine is controlled.
Der Hauptvorteil des erfindungsgemäßen Späneabstreifers gegenüber dem bisher Bekannten besteht darin, daß auch festhaftende Späne von den Schneidkanten der Schälradzähne sicher entfernt werden und daß die Abstreifelemente kaum einem Verschleiß unterliegen Außerdem ermöglicht er durch entsprechende Formgebung der Abstreifelemente, auch die Späne an treppenförmig angeschliffenen Schälrädern abzustreifen, wofür es bisher überhaupt keine sicher wirkenden Mittel gab.The main advantage of the chip scraper according to the invention over the previously known consists in the fact that also firmly adhering chips from the cutting edges the peeling wheel teeth are safely removed and that the stripping elements hardly any Subject to wear and tear, it also enables the Stripping elements, also scraping off the chips on step-shaped sharpened peeling wheels, for which there were no safe means at all up to now.
Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt. Es zeigt Bild 1 die auf einen Grundkörper fixierten Abstreifelemente, wobei die Drehung des Grundkörpers über ein Zwischengetriebe von der Schälradspindel erfolgt, und Bild 2 die auf einem Grundkörper fixierten Abstreifelemente, wobei die Drehung des Grundkörpers dadurch erfolgt, daß er an seinem Umfang eine dem Schälrad entsprechende Verzahnung aufweist, die mit dem Schälrad kämmt.Two embodiments of the invention are shown in the drawing. Figure 1 shows the stripping elements fixed on a base body, with the Rotation of the base body takes place via an intermediate gear from the peeling wheel spindle, and Fig. 2 the stripping elements fixed on a base body, the rotation of the base body takes place in that it has a peeling wheel corresponding to its periphery Has teeth that mesh with the peeling wheel.
Auf dem Grundkörper 1 sind Abstreifelemente 2 fixiert. Der Grundkörper selbst ist auf einer Spindel 3 angebracht, die sich in den Lagern 4 drehen kann, Ihr Antrieb erfolgt in Bild 1 beispielsweise über zwei Stirnräder 5 und 6 von der Schälradspindel 7 her, auf der das Schälrad 8 befestigt ist. Die Übersetzung der Stirnräder 5 und 6 wird so gewählt, daß jeweils ein Abstreifelement über die Schneidkanten eines Schälradzahnes gleitet.Stripping elements 2 are fixed on the base body 1. The basic body itself is mounted on a spindle 3 that can rotate in the bearings 4, In Figure 1, they are driven, for example, by two spur gears 5 and 6 from the Peeling wheel spindle 7 on which the peeling wheel 8 is attached. The translation of the Spur gears 5 and 6 are chosen so that each one stripping element over the cutting edges a peeling wheel tooth slides.
In Bild 2 besteht der Grundkörper 1 aus einem Stirnrad, das mit dem Schälrad 8 kämmt und dadurch seine Drehung erhält, Auf dem Grundkörper ist je Zahn ein Abstreifelement 2 fixiert, so daß dadurch automatisch jeweils ein Abstreifelement über die Schneidkanten eines Schälradzahnes gleitet.In Figure 2, the base body 1 consists of a spur gear that is connected to the Peeling wheel 8 meshes and thereby receives its rotation, on the base body is each tooth a stripping element 2 fixed, so that thereby automatically in each case a stripping element slides over the cutting edges of a peeling wheel tooth.
