Description

Die Erfindung betrifft eine durch spanlose Verformung hergestellte Differential-Verzahnung, -Riffelung oder -Kerbung, insbesondere an Riffelzylin-.dern von Spinnereimaschinen. Die Erfindung bezieht sich auch auf die dazu benötigten Werkzeuge.The invention relates to one produced by non-cutting deformation Differential toothing, corrugation or notch, especially on corrugated cylinders of spinning machines. The invention also relates to those required for this Tools.

Riffelzylinder mit differentiell geteilten Riffeln für Spinnmaschinen wurden bisher spanabhebend durch Fräsen, Hobeln oder Räumen oder auf spanlosem Wege durch Ziehen hergestellt. Diese Verfahren sind umständlich und zeitraubend und benötigen vor allem recht kostspielige Werkzeuge. Versuche, die Riffelzylinder durch das einfachere Kaltwalzverfahren herzustellen, scheiterten, weil sowohl bei Differentialteilung der Zahnlücken bei gleichbleibender Breite des Zahnfußes als auch bei Differentialteilung der Zähne bei gleichbleibendem Lückenabstand die Riffelzylinder unrund werden. Im ersten Falle ergibt sich .auf eine schmale Zahnlücke immer ein darauffolgender niedriger Zahn und auf eine breite Zahnlücke ein hoher Zahn, während im zweiten Falle der Zahn mit kleinem Zahnfuß höher wird als der Zahn mit breitem Zahnfuß.Corrugated cylinder with differentially divided corrugations for spinning machines were previously cutting by milling, planing or broaching or by non-cutting methods produced by drawing. These procedures are cumbersome and time consuming and require especially quite expensive tools. Try the corrugated cylinder by the simpler one Cold rolling processes to produce failed because both with differential pitch the tooth gaps with constant width of the tooth root as well as with differential pitch of the teeth, the corrugated cylinders become out of round if the gap spacing remains the same. in the In the first case, there is always a subsequent lower one on a narrow tooth gap Tooth and on a wide tooth gap a high tooth, while in the second case the Tooth with a small tooth root becomes higher than the tooth with a wide tooth root.

Um diesen Mängeln zu begegnen und .die spanlose Herstellung von differentiell gezahnten, geriffelten oder gekerbten Werkstücken zu ermöglichen, wird erfindungsgemäß vorgeschlagen, die Zahnlücken und Zähne der Verzahnung, Riffelung oder Kerbung paarweise zu differenzieren. Dadurch ergibt sich zwangsläufig eine richtige- Verteilung -des Werkstoffes bei genau runden Werkstücken. Die für die Herstellung derart gestalteter Werkstücke benötigten Werkzeuge (Walzen öder Ziehmatrizen) müssen dann sinngemäß die gleiche paarweise Differenzierung von Zahnlücken und Zähnen erhalten.In order to counteract these deficiencies and .the non-cutting production of differential To enable toothed, corrugated or notched workpieces is according to the invention suggested the tooth gaps and teeth of the serration, corrugation or notch in pairs to differentiate. This inevitably results in a correct distribution of the Material for precisely round workpieces. The one designed for the production of this The tools required for workpieces (rollers or drawing dies) must then be used accordingly get the same pairwise differentiation of tooth gaps and teeth.

Die Erfindung ist in .der Zeichnung beispiels-,veise veranschaulicht.The invention is illustrated by way of example in the drawing.

Fig. i ist die schaubildliche Darstellung eines Zylinderabschnittes mit der Differentialteilung gemäß Erfindung; Fig. 2 stellt die schematische Abwicklung einer differentialgeteilten Verzahnung für einen kleinen Zahn mit zugehöriger Zahnlücke dar, während Fig. 3 die gleiche Darstellung für einen großen Zahn und die zugehörige Zahnlücke wiedergibt. Der Zylinder, beispielsweise ein Riffelzylinder, wie er bei Spinnereimaschinen Verwendung findet, vom Durchmesser d hat an seinem Umfang paarweise differentiell geteilte Zähne i und 3 ... 21 und 23 sowie dazwischen befindliche Zahnlücken 2 und 4 ... 22, die in Fig. 2 und 3 stark vergrößert in Abwicklung dargestellt sind. Die dazwischen befindlichen Zähne und Zahnlücken allmählich steigender Breite, wie sie aus Fig. i ersichtlich sind, sind in den Abwicklungen nach Fig. 2 und 3 der Deutlichkeit halber weggelassen. Die Zähne i und 3 bzw. 21 und 22 sind dabei paarweise differentiell geteilt, so daß jeweils die V olumina der Zähne z, 3, 2i den Volumina der entsprechenden Zahnlücken 4, 2 bzw. 22. entsprechen. Durch diese gleichmäßige Volumenverteilung können genau runde Werkstücke im KaltwaIzverfahren oder auch im Ziehverfahren erzeugt werden, wenn,die Werkzeuge eine ebensolche Differentialteilung erhalten wie das Werkstück. Es ist lediglich eine Frage der Berechnung, wie die paarweise differential geteilten Zähne so über den Umfang zu verteilen sind, @daß sie in dem gewünschten Abstand aufgehen. Die Anzahl der Zähne und die Größenordnung der Differenzierung sind vom Durchmesser des Werkstückes und von der gewählten Teilung abhängig.Fig. I is a perspective view of a cylinder section with the differential pitch according to the invention; FIG. 2 shows the schematic development of a differentially divided toothing for a small tooth with an associated tooth gap, while FIG. 3 shows the same illustration for a large tooth and the associated tooth gap. The cylinder, for example a corrugated cylinder as it is used in spinning machines, of diameter d has on its circumference differentially divided teeth i and 3 ... 21 and 23 as well as tooth gaps 2 and 4 ... 22 in between, which are shown in Fig. 2 and 3 are shown greatly enlarged in the development. The teeth and gaps between the teeth of gradually increasing width, as can be seen in FIG. 1, are omitted in the developments according to FIGS. 2 and 3 for the sake of clarity. The teeth i and 3 or 21 and 22 are differentially divided in pairs so that the volumes of the teeth z, 3, 2i correspond to the volumes of the corresponding tooth gaps 4, 2 and 22 respectively. Through this even volume distribution, precisely round workpieces can be produced in the cold rolling process or also in the drawing process, if the tools have the same differential division as the workpiece. It is only a question of calculating how the pair of differentially divided teeth are to be distributed over the circumference in such a way that they open at the desired spacing. The number of teeth and the magnitude of the differentiation depend on the diameter of the workpiece and the pitch selected.

Sinngemäß sind daher die Werkzeuge zum Herstellen differentiell verzahnter oder gekerbter Werkstücke unter entsprechender Berücksichtigung der Fertigungserfordernisse, wie Festigkeit und Härte, anzufertigen.Accordingly, the tools for manufacturing are differentially interlocked or notched workpieces, taking into account the manufacturing requirements, like strength and hardness.

Die Erfindung ist natürlich nicht auf Riffelzylinder von Spinnmaschinen beschränkt, sondern kann auch bei anderen Werkstücken angewendet werden, bei denen eine Differentialteilung am Umfang erwünscht ist.The invention is of course not applicable to corrugated cylinders of spinning machines limited, but can also be used for other workpieces where a differential division on the circumference is desired.
