Description
Die Erfindung betrifft ein Verfahren zum Walzen einer Verzahnung an einem ring- oder scheibenförmigen Werkstück mit Hilfe einer drehantreibbaren das Werkstück aufnehmenden Hohlform, deren Innenfläche die Gegenform des fertiggewalzten Werkstückes darstellt.The invention relates to a method for rolling a toothing an annular or disc-shaped workpiece with the help of a rotatable das Workpiece-receiving hollow form, the inner surface of which is the counterpart of the finish-rolled Represents workpiece.
Die Herstellung der Verzahnung eines Werkstückes mittels einer die Gegenverzahnung aufweisenden Hohlform, worin sich das Werkstück in seiner gesamten Breite abwälzt, ist bekannt. Dieses Abwälzverfahren in einer derartigen Hohlform in einer Drehrichtung gewährleistet keinesfalls die präzise Ausbildunc, der gewünschten Zahnform, so daß diese durch anschließende spanabhebende Arbeit erst herstellbar ist. Durch das linienhafte Abwälzen auf der gesamten Zahnbreite ist der erforderliche Kraftaufwand, auch bei der Warmverformung sehr hoch. Darüber hinaus läßt sich dieses Verfahren nur für die Herstellung von Stirnzahnrädern verwenden.The production of the toothing of a workpiece by means of a die Counter-toothing having hollow shape, in which the workpiece is in its entirety Width is known This rolling process in such a hollow mold in one direction of rotation in no way guarantees the precise training desired Tooth shape, so that this can only be produced by subsequent machining work is. Due to the linear rolling over the entire face width, the required Effort, also very high during hot forming. In addition, this Use this process only for the manufacture of spur gears.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, das die präzise Ausbildung jeder Zahnform jeder Breite bei geringem Kraftaufwand auf dem Wege der Kaltverformung auch bei Kegelrädern ermöglicht.The invention is based on the object of creating a method that the precise formation of every tooth shape of every width with little effort on the way of cold deformation also made possible for bevel gears.
Erfindungsgemäß wird dies dadurch erreicht, daß das Werkstück in der Hohlform von einem Rand ausgehend in Längsrichtung der herzustellenden Zähne kontinuierlich mittels Walzens abgestreckt wird.According to the invention this is achieved in that the workpiece in the Hollow shape starting from an edge in the longitudinal direction of the teeth to be produced continuously is ironed by rolling.
Die Erfindung wird nachstehend an einem Ausführungsbeispiel näher erläutert. In der Zeichnung zeigt F i g. 1 die Arbeitsweise des Verfahrens beim Walzen von Stirnradkränzen und F i g. 2 die Arbeitsweise des Verfahrens beim Walzen von Kegelrädern.The invention is explained in more detail below using an exemplary embodiment explained. In the drawing, F i g. 1 the operation of the procedure at Rolling of spur gear rings and F i g. 2 the mode of operation of the rolling process of bevel gears.
In ein aus den Teilen 1 und 2 bestehendes rotierendes Futter wird ein ringförmiger Rohling 3 eingelegt. Der Werkzeugring 2 trägt als Innenverzahnung 4 die negative Zahnform des zu fertigenden Zahnkranzes. Ein in der Zeichnung nicht dargestellter Werkzeugschlitten trägt den Rollenhalter 5 mit einer drehbar gelagerten Walzrolle 6. Der durch eine Axialbewegung der abgestuften Walzrolle 6 entstehende zeilenweise Walzvorgang bewirkt, daß der Rohling derart umgeformt wird, daß ein genaues Abbild des Futters entsteht.In a rotating chuck consisting of parts 1 and 2 an annular blank 3 is inserted. The tool ring 2 carries as internal teeth 4 the negative tooth shape of the gear ring to be manufactured. One in the drawing is not tool slide shown carries the roll holder 5 with a rotatably mounted Rolling roller 6. The one produced by an axial movement of the stepped rolling roller 6 line-by-line rolling process causes the blank is deformed in such a way that a an exact image of the feed is created.
In der gleichen Weise lassen sich nach F i g. 2 Kegelräder herstellen.In the same way, according to FIG. Make 2 bevel gears.
In ein aus den Teilen 11 und 12 bestehendes Futter wird der scheibenförmige Rohling 13 eingelegt. Der Werkzeugring 11 trägt als Innenverzahnung 14 die negative Zahnform des zu fertigenden Kegelrades. Ein schwenkbarer Werkzeugschlitten trägt den Rollenhalter 15 mit einer drehbar gelagerten Walzrolle 16. Die Walzbewegung verläuft hier in Richtung des Kegelmantels, wobei für die Einhaltung des richtigen Walzspaltes das Gesetz der Volumenkonstanz Gültigkeit hat.In a chuck consisting of the parts 11 and 12, the disc-shaped Blank 13 inserted. The tool ring 11 has the negative internal toothing 14 Tooth shape of the bevel gear to be manufactured. A swiveling tool slide carries the roller holder 15 with a rotatably mounted roller 16. The rolling movement runs here in the direction of the cone shell, whereby for compliance with the correct Roll gap the law of constant volume is valid.
Die durch dieses aufgezeigte Verfahren hergestellten Zahnradkränze werden nach ihrer Verformung mittels pneumatisch betriebenen oder mechanischen in der Zeichnung nicht dargestellten Auswerfer aus dem Futter herausgedrückt.The ring gears produced by this method shown are deformed by means of pneumatically operated or mechanical in the drawing, not shown, pushed the ejector out of the chuck.
