Description

Verfahren zur Herstellung von Gelenkwellen. Die Gelenkwellen aus aneinandergelenkten Gliedern sind derart zusammengesetzt, daß das eine Glied in einen Einschnitt des benachbarten Gliedes eingreift und durch einen Querstift gehalten wird. Damit nun die genügende Beweglichkeit in der Ebene des Querstiftes und des Gliedes gewahrt bleibt, muß der Einschnitt breiter sein als das in ihm steckende Wellenglied. Durch .dieses Erfordernis entsteht aber der Nachteil, daß auch Spiel zwischen beiden Gliedern in der Drehrichtung vorhanden ist, was für solche Wellen, die nicht dauernd gleichförmig sich drehen, insofern mangelhaft ist, weil dann das .große Gesamtspiel der Wellen in der Drehrichtung zu stoßweisem Arbeiten der Welle Anlaß gibt. Aus diesem Grande hat man den Einschnitt in den Wellengliedern nach außen und innen vom Querstift aus über die der .Dicke ,des benachbarten Gliedes entsprechende Breite erweitert, um die Biegsamkeit der Welle voll zu erhalten, das Spiel in der Drehrichtung aber zu verhindern. Die Herstellung dieses Einschnittes erfolgte bisher durch zweimaliges Fräsen, was aber sehr umständlich und teuer ist. Außerdem mußte der Querstift an beiden Enden versenkt vernietet werden, damit er nicht über len Umfang des Gliedes hervorstand.Process for the production of cardan shafts. The cardan shafts made of articulated Links are composed in such a way that one link is in a cut of the adjacent link engages and is held by a cross pin. So now the sufficient mobility in the plane of the transverse pin and the link is preserved remains, the incision must be wider than the shaft link stuck in it. By .this requirement, however, has the disadvantage that there is also play between the two members in the direction of rotation is present, what for such waves, which are not continuously uniform rotate, insofar as it is defective, because then the .large overall game of the waves gives rise to intermittent operation of the shaft in the direction of rotation. For this grande one has the incision in the shaft links outwards and inwards from the cross pin extended over the width corresponding to the thickness of the adjacent link, in order to fully maintain the flexibility of the shaft, but the play in the direction of rotation to prevent. The production of this incision has so far been carried out twice Milling, which is very cumbersome and expensive. In addition, the cross pin had to be on both ends are countersunk riveted so that it does not exceed the circumference of the limb protruded.

Gegenstand der Erfindung ist ein Verfahren zur Herstellung dieser Einschnitte, durch das die erwähnten Mängel beseitigt werden; insbesondere ist es sehr einfach und leicht durchführbar, so daß die Kosten für derartige Gelenkwellen erheblich verringert werden.The invention relates to a method for producing these Cuts through which the mentioned shortcomings are eliminated; in particular it is very simple and easy to carry out, so that the cost of such cardan shafts can be reduced significantly.

Das neue Verfahren wird in folgender Weise ausgeführt: In jedem Ende des kurzen, stabförmigen Gliedes i wird ein breiter Längsschnitt 2 mit parallelen Seiten durch Fräsen oder Hobeln hergestellt (.Abb. i), dann werden die Löcher 3 in den beiden stehenbleilienden Lappen d. gebohrt und alsdann diese nach dem Zwischenlegen .eines Formstückes 5 in der Mitte, wo die Löcher sich. 1"efinden, etwas nach innen durch Pressen durchgebogen (Abb. 2), wodurch der Einschnitt die gewünschte Gestalt erhält, die dem benachbarten Gliede 6 .die erforderliche Beweglichkeit, aber kein Spiel in der Drehrichtung läßt. Außerdem kann der Querstift 7 mit rundem Kopf 8 vernietet werden, weil infolge des Durchbiegens für diesen der nötige Raum geschaffen ist.The new procedure is carried out in the following way: In each end of the short, rod-shaped limb i becomes a wide longitudinal section 2 with parallel Sides made by milling or planing (.Fig. I), then the holes 3 in the two standing lobes d. drilled and then this after interposing .a shaped piece 5 in the middle, where the holes are. 1 "find something inside bent by pressing (Fig. 2), giving the incision the desired shape receives the adjacent link 6. the necessary mobility, but no Can play in the direction of rotation. In addition, the cross pin 7 with a round head 8 be riveted because the necessary space is created for this as a result of the sagging is.
