Description

Körnerlagerschraube für Uhr-, Lauf-, Zählwerke u. dgl. Die Erfindung betrifft eine Abänderungsform der Körnerlagerschxaube für Uhr-, Lauf-, Zählwerke u. dgl. nach Patent 434721 und bezweckt, die Herstellung der Schraube wesentlich zu vereinfachen und zu verbilligen.Center bearing screw for clocks, running mechanisms, counters and the like. The invention concerns a modification of the grain bearing screw for clocks, running mechanisms and counters and the like according to patent 434721 and aims to make the manufacture of the screw essential to simplify and cheaper.

Der Grundgedanke der Haupterfindung, den die Körnersenkung enthaltenden Teil der Lagerschraube zwecks Erzielung einer glatten Oberfläche aus einem weichen, auf dem Vergütungswege härtbaren Baustoff auf kaltem Wege dicht zu pressen und zu härten, ist auch bei der neuen Ausführung der Schraube beibehalten, jedoch in der Weise ausgeführt, daß der ganze Schraubenkörper mit der unmittelbar darin vorgesehenen Körnersenkung, jedoch ohne Gewinde, aus dem betreffenden Baustoff, z. B. Chromstahl oder Chromnickelstahl, als Preßling auf kaltem Wege hergestellt, dann z. B. durch Rollen mit Gewinde versehen und schließlich gehärtet wird. Hierbei bleibt die durch den Preßvoxgang erzeugte glatte Oberfläche der Körnersenkung unverändert und damit die ölhaltende Eigenschaft der Lagerschraube gewahrt.The basic idea of the main invention, the one containing the grain subsidence Part of the bearing screw for the purpose of achieving a smooth surface made of a soft, to press hardenable building material tightly in the cold way and to close hardening is retained in the new version of the screw, but in the Executed way that the whole screw body with the provided directly therein Countersink, but without a thread, from the building material in question, e.g. B. chrome steel or chrome-nickel steel, produced as a compact by cold means, then z. B. by Rollers are threaded and finally hardened. This stays through the Preßvoxgang produced the smooth surface of the grain depression unchanged and thus the oil-retaining property of the bearing screw is preserved.

Dadurch, daß die neue Körnerlagerschraube aus einem Stück hergestellt ist, also keines besonderen Einsatzkörpers für das Körnerlager bedarf, wird die Herstellung der Schraube wesentlich vereinfacht und verbilligt.Because the new center bearing screw is made from one piece is, so does not require a special insert for the grain store, the Production of the screw is much easier and cheaper.

Abb. i zeigt den auf kaltem Wege in einem Arbeitsvorgang gepreßten Schraubenkörper mit der darin vorgesehenen Körnersenkung i in senkrechtem Schnitt.Fig. I shows the cold pressed in one work process The screw body with the countersink i provided therein in a vertical section.

Abb. a ist eine Ansicht der fertigen Körnerlagerschraube, deren Gewinde 5 vor dem Härten zweckmäßig durch Rollen hergestellt ist.Fig. A is a view of the finished center punch bearing screw, its threads 5 is suitably made by rolling prior to hardening.
