Description

3030th

Die Erfindung betrifft eine Schwertwalze für Schlitzrohrkalibergerüste in einer Anlage zum Längsnahtschweißen von Rohren nach dem Oberbegriff des Anspruchs 1.The invention relates to a sword roll for slotted tube caliber frames in a system for longitudinal seam welding of pipes according to the preamble of claim 1.

Bisher wurden Schwerter eingesetzt (US 41 65 628), die reibend auf einem Lagerinnenring eine Differenzbewegung zum Walzenkaliber ausführen. Hierbei entstand ein Verschleiß an der Walze und an dem Schwertring, der durch eingespülten Walzzunder noch verstärkt wurde. Entsprechend hoch war der Verbrauch an Schwertmaterial und Walzen, da Nacharbeiten nur in begrenztem Umfang möglich sind.So far swords have been used (US 41 65 628), the friction on an inner bearing ring a differential movement run to the roller caliber. This resulted in wear on the roller and on the sword ring, which was reinforced by the mill scale that was washed in. The consumption was correspondingly high Blade material and rollers, as reworking is only possible to a limited extent.

Aufgabe der Erfindung ist es, eine Schwertlagerung in Schlitzrohrkalibergerüsten zu schaffen, die ein reibungsfreies Abrollen des Schwertes ermöglicht. The object of the invention is to create a sword bearing in slotted tube caliber frames that enables the sword to roll without friction.

Gelöst wird diese Aufgabe erfindungsgemäß durch die im Patentanspruch 1 angegebenen Merkmale.This object is achieved according to the invention by the features specified in claim 1.

Vorzugsweise Weiterbildungen ergeben sich aus den Unteransprüchen.Preferably further developments result from the subclaims.

Die erfindungsgemäße Schwertlagerung verringert den Nacharbeitungsaufwand und erhöht die Lebensdauer der Walzen und der Schwerter. Außerdem wird eine Zundereinspülung vermieden.The sword bearing according to the invention reduces the reworking effort and increases the service life the reels and the swords. In addition, a flushing in of scale is avoided.

In der Zeichnung ist eine mögliche Ausführungsform einer erfindungsgemäßen Schwertlagerung schematisch dargestellt.A possible embodiment of a sword bearing according to the invention is shown schematically in the drawing shown.

In dieser Zeichnung sind die beiden Walzenhälften 1 mit einem Mittelteil verbunden, das als Lagerinnenring 2 dient. In den verbleibenden Zwischenraum oder Spalt 9 wird ein äußerer Trägerring 3 eingesetzt, der beidseitig mit Schwertringen 4 versehen ist, die aus hochfestem bzw. verschleißfestem Material bestehen. Zwischen Lagerinnenring 2 und Trägerring 3 sind Lagerrollen 6 angeordnet, die ein Drehen des Trägerringes 3 mit den Schwertringen 4 über dem Lagerinnenring 2 ermöglichen. Zur Vermeidung des Eindringens von Zunder ist der Trägerring 3 beidseitig mit den Dichtungen 5 und der Zwischenraum zwischen Lagerinnenring 2 und Trägerring 3 zum Schutz der Lagerrollen 6 ebenfalls beidseitig mit Dichtungen 7 versehen. Zum Einbringen der Schmiermittel ist eine Zuführung 8 im Trägerring 3 vorgesehen.In this drawing, the two roller halves 1 are connected to a middle part, which acts as the inner bearing ring 2 serves. In the remaining space or gap 9, an outer carrier ring 3 is used, the is provided on both sides with sword rings 4, which are made of high-strength or wear-resistant material. Bearing rollers 6 are arranged between the inner bearing ring 2 and the carrier ring 3, which rotate the Allow the carrier ring 3 with the sword rings 4 over the bearing inner ring 2. To avoid the Ingress of scale is the carrier ring 3 on both sides with the seals 5 and the space between the bearing inner ring 2 and carrier ring 3 to protect the Bearing rollers 6 are also provided with seals 7 on both sides. To introduce the lubricant is a Feed 8 is provided in the carrier ring 3.

Im Einsatz der Schwertwalze in dem Schlitzrohrkalibergerüst rollt der Schwertring auf dem Mehrfachrollenlager ab, so daß der Verschleiß im Gegensatz zu den festen Schwertlagerungen wesentlich vermindert wird.When the sword roller is in use in the slotted tube caliber frame, the sword ring rolls on the multiple roller bearing from, so that the wear is significantly reduced in contrast to the fixed sword bearings.
