Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Lagerringen für Kegelrollenlager, wobei von einem hohlzylinderartigen Rohling ausgegangen wird, der mit einer Stempeleinrichtung weiterbearbeitet wird.The The invention relates to a method for producing bearing rings for tapered roller bearings, wherein it is assumed that a hollow cylinder-like blank, the is processed with a stamp device.
Bislang
werden Innen- und Außenringe
von Kegelrollenlagern dadurch hergestellt, dass der Innenring aus
einem im wesentlichen hohlzylinderförmigen Innenringrohling und
der Außenring
aus einem ebenfalls im wesentlichen hohlzylinderartigen Außenringrohling,
dessen Abmessungen von denen des Innenringrohlings verschieden sind,
unter anderem durch Materialabtrag und/oder Umformen entsprechend
geformt werden. Derartiges ist beispielsweise aus der
Eine Aufgabe der Erfindung ist es, ein Verfahren zum Herstellen von Lagerringen für Kegelrollenlager zu schaffen, so dass die Lagerringe einfach und kostengünstig herstellbar sind.A The object of the invention is a method for producing bearing rings for tapered roller bearings to create so that the bearing rings simple and inexpensive to produce are.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den Verfahrensschritten nach Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.These The object is achieved by a Method with the method steps according to claim 1 solved. advantageous Embodiments are described in the subclaims.
Gemäß Anspruch 1 beinhaltet ein Verfahren zum Herstellen von Lagerringen für Kegelrollenlager ein Zertrennen eines hohlzylinderartigen Rohlings, so dass gleichzeitig ein Innen- und ein Außenringrohling entstehen, die jeweils eine kegelstumpfmantelartige Oberfläche aufweisen.According to claim 1 includes a method of manufacturing tapered roller bearing bearing races Dicing a hollow cylinder-like blank, so that at the same time an inner and an outer ring blank arise, each having a frustoconical surface.
Gegenüber dem eingangs beschriebenen Verfahren, bei dem Innen- und Außenring eines Kegelrollenlagers aus zwei separaten, voneinander verschiedenen hohlzylinderförmigen Rohlingen unter anderem durch Materialabtrag und/oder Umformen hergestellt werden, ist ein Herstellen der Innen- und Außenringe gemäß dem Anspruch 1 mit einem deutlich geringeren Materialabtrag und/oder vereinfachtem Umformen zu bewerkstelligen, da der Innen- und Außenringrohling aus einem gemeinsamen Rohling durch ein derart gestaltetes Zertrennen des Rohlings erzeugt werden, dass sowohl dem Innen- als auch dem Außenringrohling eine kegelstumpfmantelartige Oberfläche verliehen wird und somit deren Abmessungen den Abmessungen der fertigen Innen- und Außenringe bereits wesentlich ähnlicher sind als bei vorgenannten, voneinander verschiedenen hohlzylinderartigen Rohlingen. Dadurch werden mit Vorteil Herstellzeit, Material und damit Kosten eingespart. Weiterhin werden mit Vorteil auch die den Materialabtrag und/oder das Umformen bewerkstelligenden Werkzeuge entlastet.Compared to the initially described method, in the inner and outer ring a tapered roller bearing of two separate, mutually different hollow cylindrical Blanks produced among other things by material removal and / or forming are, is a manufacture of the inner and outer rings according to the claim 1 with a significantly lower material removal and / or simplified Forming to accomplish, since the inner and outer ring blank from a common blank by such a designed severing be generated in the blank, that both the interior and the Outer ring blank a truncated cone-like surface is imparted and thus the dimensions of which are the dimensions of the finished inner and outer rings already much more similar are as in the aforementioned, different from each other hollow cylinder-like Blanks. As a result, advantageously manufacturing time, material and thus saving costs. Furthermore, with advantage and the Material removal and / or the reshaping accomplishing tools relieved.
