Description
LagerschaleBearing shell
Es ist bekannt, Schmierflüssigkeit beiIt is known to use lubricating fluid
Lagern zwischen Zapfen bzw. Welle 'und Lagerfläche unter Druck einzuführen, um eine ganzflächige Schmierung mit Sicherheit zu gewährleisten.Bearings between the journal or shaft 'and bearing surface to introduce under pressure to a ensure full-surface lubrication with certainty.
Die Erfindung betrifft nun eine Lagerschale, insbesondere für Walzwerke, die mit -besonderen Schmiereinsätzen aus einer Graphitmisch'ung versehen ist. Diese Schmiereinsätze sind allein nicht wirksam gegen den schnellen Verschleiß und können auch Anfressungen nicht vermeiden. Es ist bei solchen Lagern notwendig, dem Lager in Form eines Schmierfilms Wasser zuzuführen. Die Versuche haben bisher gezeigt, daß ein kontinuierlicher Schmierfilm des Wassers, das von außen zwischen Lagerschale und Zapfen eingebracht wurde, nicht ausreichend war.The invention now relates to a bearing shell, in particular for rolling mills with - is provided with special lubricating inserts made from a graphite mixture. These lubrication inserts are not effective on their own against rapid wear and tear and can also be corroded do not avoid. With such bearings, it is necessary to supply the bearing with water in the form of a lubricating film. The experiments have so far shown that a continuous lubricating film of the water, the was introduced from the outside between the bearing shell and the journal was not sufficient.
Erfindungsgemäß wird auf die eingangs erwähnte, an sich bekannte: Maßnahme zurückgegriffen und der Unvollkommenheit der mit Schmiereinsätzen versehenen Lager dadurch abgeholfen, daß die Lagerschale mit nutenförmigen Ausnehmungen versehen ist, aus denen heraus in der bekannten Weise Wasser unter Druck zwischen Zapfen (Welle) und Lagerfläche eingebracht wird. Hierdurch wird eine Wasserfilmbildung in vollkommenster Form gewährleistet.According to the invention, recourse is made to the measure mentioned at the beginning and known per se and the imperfection of the bearing provided with lubricating inserts remedied by the fact that the bearing shell with groove-shaped Recesses is provided, out of which in the known manner water under pressure between the pin (shaft) and Storage area is introduced. This creates a perfect water film formation Shape guaranteed.
Die in der Ebene der Lagerfläche der Lagerschale liegenden Kanten der Nut bzw. der Nuten werden zweckmäßig abgerundet, wodurch dem Wasser der Eintritt zwischen Welle und Lagerfläche erleichtert wird, wobei noch im Drehsinne der Welle das Kühlwasser mitgerissen wird (Pumpwirkung). \ The edges of the groove or the grooves lying in the plane of the bearing surface of the bearing shell are suitably rounded, which facilitates the entry of water between the shaft and the bearing surface, with the cooling water being carried along in the direction of rotation of the shaft (pumping effect). \
In der Zeichnung ist die neue Lagerschale in den Abb. 1 bis 3 in der Draufsicht, im Längsschnitt und im Querschnitt dargestellt.In the drawing, the new bearing shell in Figs. 1 to 3 in plan view, in Longitudinal section and shown in cross section.
Die Lagerschale ist mit 1 und die Schmiereinlagen, die aus einem im Graphiteinschluß aufweisenden Werkstoffe, beispielsweise aus einer Mischung von Graphit und einem Bindefüllmittel, besteht, mit 2 bezeichnet.The bearing shell is with 1 and the lubricating inserts, which consist of one in the graphite inclusion containing materials, for example from a mixture of graphite and a binder filler, consists, denoted by 2.
Im Ausführungsbeispiel sind beiderseits an der unteren Scheitelpunktlinie 3 zwischen den Graphitschmiereinsätzen 2 die Nuten 3 vorgesehen, die, wie die Abb. 1 zeigt, zwecks Verstärkung bei 4 Überbrückungen aufweisen. In tdiese nutenförmigen Ausnehmungen, die, wie Abb. 3 zeigt, nach oben abgerundet sind, wird unter Druck stehendes Wasser eingebracht, das, wie oben erläutert, zwischen Welle und Lagerschale gepreßt wird und somit die größte Wirkung bezüglich der Schmierfilmbildung in Verbindung mit den Graphiteinlagen gewährleistet.In the exemplary embodiment are on both sides at the lower vertex line 3 between the Graphite lubricating inserts 2, the grooves 3 are provided, which, as Fig. 1 shows, for the purpose of reinforcement with 4 bridges. In these groove-shaped recesses, as Fig. 3 shows, are rounded at the top, pressurized water is introduced, which, as explained above, is pressed between the shaft and the bearing shell and thus the Greatest effect on the formation of a lubricating film in connection with the graphite inlays guaranteed.
