Description
Verfahren zur Herstellung einer Welle mit bruchfesten Lagerzapfen für Uhrwerke und feinmechanische Apparate Nach einem noch nicht zum Stand der Technik gehörenden Vorschlag werden bruchfeste Lagerzapfen hergestellt, die im Gegensatz zu den martensitisch gehärteten brüchigen Zapfen aus patentiertem Stahldraht (Klaviersaitendraht) bestehen, dem durch Kaltziehen Festigkeitswerte von über 200 kg/mm2 verliehen wurden. Im schweizerischen Patent 311285 ist ein Verfahren zur Herstellung eines solchen Lagerzapfens beschrieben.Process for the production of a shaft with unbreakable bearing journals for clockworks and precision mechanical devices After a not yet state of the art According to the proposal, unbreakable bearing journals are made, which in contrast to the martensitically hardened brittle tenons made of patented steel wire (piano wire) exist, which has been given strength values of over 200 kg / mm2 through cold drawing. In the Swiss patent 311285 there is a method for the production of such a Bearing pin described.
Solche Zapfen haben nun wohl eine große Bruchfestigkeit. Sie haben aber den Nachteil, daß sie magnetisch sind und leicht rosten.Such pegs now have a high breaking strength. They have but the disadvantage that they are magnetic and rust easily.
Es ist nun gelungen, ein an sich bekanntes rostfreies und amagnetisches Drahtmaterial so zu behandeln, daß sich daraus ebenfalls z. B. Unruhwellen anfertigen lassen, die Festigkeitswerte von über 200 kg/mm2 aufweisen und deren Zapfen bruchsicher sind.It has now been possible to create a well-known rustproof and non-magnetic To treat wire material so that it also z. B. Make balance shafts that have strength values of over 200 kg / mm2 and their pins are unbreakable are.
Die vorliegende Erfindung betrifft demnach ein Verfahren zur Herstellung einer Welle mit bruchfesten Lagerzapfen für Uhrwerke und feinmechanische Apparate, das sich dadurch kennzeichnet, daß mindestens die Lagerzapfen der Welle aus einem geeigneten rostsicheren Draht hergestellt werden, der unmagnetisch oder höchstens schwach magnetisch ist und auf hohe Temperatur von über 1000° C erhitzt und abgeschreckt und anschließend auf Festigkeitswerte von über 200 kg/mm2 und auf Härten von über 600 Vickers kalt heruntergezogen wird. Gegebenenfalls findet nachträglich noch eine Wärmebehandlung zwischen 200 und 600° C statt.The present invention accordingly relates to a method of manufacture a shaft with break-proof bearing journals for clockworks and precision mechanical devices, which is characterized in that at least the journal of the shaft from one suitable rust-proof wire can be made, which is non-magnetic or at most is weakly magnetic and heated and quenched to a high temperature of over 1000 ° C and then to strength values of over 200 kg / mm2 and hardnesses of over 600 Vickers is pulled down cold. If necessary, there is another one afterwards Heat treatment between 200 and 600 ° C takes place.
Eine auf diese Weise hergestellte Unruhwelle mit Zapfen von im Durchmesser 0,09 mm bleibt, wie Versuche gezeigt haben, unbeschädigt, wenn eine mit dieser Unruhwelle versehene Uhr in der ungünstigsten Lage derselben von einer Höhe von 0,8 bis 1 m auf eine Stahlplatte fallen gelassen wird. Die Festigkeit von über 200 kg/mm2 genügt somit, um die Zapfen der Unruhwelle praktisch unzerbrechlich zu machen. Das Drahtmaterial läßt sich auf dem Drehautomaten bearbeiten und läßt so eine präzise Massenfertigung zu.A balance shaft made in this way with journals of in diameter As tests have shown, 0.09 mm remains undamaged if one with this balance shaft provided clock in the most unfavorable position of the same from a height of 0.8 to 1 m dropped onto a steel plate. The strength of over 200 kg / mm2 is sufficient thus to make the journals of the balance shaft practically unbreakable. The wire material can be machined on the automatic lathe and thus allows precise mass production to.
Als Beispiel einer zur Herstellung der Welle geeigneten Legierung sei hier eine an sich bekannte Legierung erwähnt, die sich für die Herstellung guter Uhrfedern bewährt hat und die sich erfindungsgemäß auch zu bruchsicheren Lagerzapfen verarbeiten läßt. Die Zusammensetzung der Legierung ist folgende: 4019/o Co, 26% Ni, 10 % Cr, 41/o W, 4% Mo, 0,2% Be, 1,0'% Ti, 2'% Mn + Si, Rest Fe.As an example of an alloy suitable for making the shaft a known alloy should be mentioned here, which is suitable for the production of good Clock springs has proven itself and, according to the invention, also become unbreakable bearing journals can be processed. The composition of the alloy is as follows: 4019 / o Co, 26% Ni, 10% Cr, 41 / o W, 4% Mo, 0.2% Be, 1.0% Ti, 2% Mn + Si, remainder Fe.
Außer dieser Legierung, die nur als ein Beispiel dienen soll, können noch viele andere Legierungen zusammengestellt werden, die rostsicher, schwach oder gar nicht magnetisch sind und sich auf die erwähnte hohe Festigkeit kalt verformen lassen. Solche Legierungen basieren vorzugsweise auf den Elementen Fe, Ni, Co, Cr, Mo, W, mit oder ohne Zusätze von Be, Ti, Nb, Ta und C.Besides this alloy, which should only serve as an example, you can Still many other alloys can be put together that are rustproof, weak or are not magnetic at all and are cold deformed to the aforementioned high strength permit. Such alloys are preferably based on the elements Fe, Ni, Co, Cr, Mo, W, with or without additions of Be, Ti, Nb, Ta and C.
Die nach dem erfindungsgemäßen Verfahren hergestellten Lagerzapfen haben gegenüber denen aus martensitisch gehärtetem Stahl oder aus Klaviersaitendraht bessere Gleiteigenschaften, insbesondere weil sich im Lager kein Reibrost bilden kann.The bearing journals produced by the method according to the invention have compared to those made of martensitically hardened steel or piano wire better sliding properties, especially because there is no friction rust in the bearing can.
Die Wellen, um die es sich hier handelt, können verschiedene Formen aufweisen, von denen in den F i g. 1, 2 und 3 der Zeichnung als Beispiele drei gezeigt sind.The waves we are talking about here can take various forms have, of which in FIGS. 1, 2 and 3 of the drawing are shown as examples three are.
In F i g. 1 ist a die aus gewöhnlichem Stahl bestehende Unruhwelle eines Uhrwerkes. Diese Unruhwelle a weist in ihren Endteilen Bohrungen auf, in die nach dem obigen Verfahren hergestellte Lagerzapfen b eingesetzt sind.In Fig. 1 a is the balance shaft made of ordinary steel of a clockwork. This balance shaft a has holes in its end parts into which Bearing journals produced by the above method are used.
Gemäß F i g. 2 wird über einen nach obigem Verfahren hergestellten Draht c ein dickwandiges Metallrohr d geschoben, das einem Ziehvorgang unterworfen wird, bis es auf dem Draht c festsitzt. Das Metallrohr wird dann entsprechend dem in F i g. 2 gezeigten Fertigprofil bearbeitet und an seinen Enden bis auf den Durchmesser des Drahtes c abgesetzt, um die Lagerzapfen cl zu bilden.According to FIG. 2 is produced using a method above Wire c pushed a thick-walled metal tube d, which is subjected to a drawing process until it is stuck on wire c. The metal pipe is then according to the in Fig. 2 machined finished profile shown and at its ends down to the diameter of the wire c deposited to form the bearing journals cl.
In F i g. 3 ist eine Welle gezeigt, die einen nach dem obigen Verfahren hergestellten Wellenkörper e aufweist, auf dessen Mittelteil e1 eine darauf aufgeschobene, profilierte Metallhülse f sitzt. Der Wellenkörper e hat konische Endteile e2, die an ihrem Außenende als Lagerzapfen e3 ausgebildet sind. Anstatt konisch könnten die Endteile e2 auch als Rotationskörper ausgebildet sein, dessen Erzeugende eine kubische Parabel wäre. Gegebenenfalls könnte die Hülse fauch einen integrierenden Teil der Welle e bilden. In diesem Falle würde die Welle nach der fertigen Behandlung eines dickeren Runddrahtes aus diesem letzteren herausgearbeitet, z. B. herausgeschliffen. Schließlich wäre es auch möglich, die Metallhülse f wegzulassen und die Unruh mit ihrer Nabe direkt auf dem Mittelteil e1 des Wellenkörpers aufzuschieben.In Fig. Referring to Figure 3, a shaft is shown which is produced according to the above method manufactured shaft body e has, on the middle part e1 a profiled metal sleeve f pushed onto it is seated. The shaft body e has conical end parts e2, which are designed as bearing pins e3 at their outer end. Instead of conical, the end parts e2 could also be designed as bodies of revolution, whose generator would be a cubic parabola. If necessary, the sleeve could hiss form an integral part of wave e. In this case the wave would follow the finished treatment of a thicker round wire worked out of this latter, z. B. ground out. Finally, it would also be possible to omit the metal sleeve f and to push the balance with its hub directly onto the middle part e1 of the shaft body.
