Description
Die Erfindung bezieht sich auf eine Lagerung der Rollenelektroden von Widerstandsnahtschweißmaschinen. Es ist bekannt, gewöhnliche Stahlwellen in einem aus Bronze hergestellten Lager zu halten. Bei Widerstandsnahtschweißmaschinen kann aber diese Art der Lagerung nicht angewendet werden, weil die Schweißstromzuführung über diese Lagerung erfolgt, die für den Schweißstrom einen zu hohen Widerstand darstellt. Die Wärmeentwicklung wäre bei einem solchen Lager zu stark.The invention relates to a mounting of the roller electrodes of resistance seam welding machines. It is known to use ordinary steel shafts in to hold a bearing made of bronze. With resistance seam welding machines but this type of storage cannot be used because of the welding current supply This storage takes place, the too high a resistance for the welding current represents. Such a bearing would generate too much heat.
Es hat sich nun aber überraschenderweise herausgestellt, daß -°s doch möglich ist, die guten Eigenschaften der bekannten Lagerung auch bei Widerstandsnahtschweißmaschinen zur Anwendung zu bringen, und zwar dadurch, daß man sowohl den Lagerkörper als auch die Welle selbst aus einem elektrisch gut leitenden Werkstoff, z. B. Bronze, ausführt und zwischen Lagerkörper und Welle eine Hülse aus Stahl anordnet. Versuche haben überraschend bestätigt, daß die zwischen-"schaltete Stahlhülse keinen nennenswerten elektrischen Widerstand bietet, daß aber die Lagereigenschaft im Vergleich zu den bislang benutzten Lagern ganz grundlegend verbessert wird.But it has now surprisingly turned out that - it is it is possible to use the good properties of the known bearings even in resistance seam welding machines to bring to use, namely by having both the bearing body and the shaft itself made of a material with good electrical conductivity, e.g. B. Bronze, executes and a sleeve made of steel is arranged between the bearing body and the shaft. Have attempts Surprisingly confirms that the intermediate steel sleeve is not worth mentioning electrical resistance offers that but the bearing property compared to the previously used bearings is fundamentally improved.
Die Stahlhülse kann entweder am Lagerhörp,er selbst oder auch auf der sich bewegenden Welle befestigt sein. In b°sond-ers vorteilhafter Weise ist die Hülse aufgeschrumpft oder aufgepreßt.The steel sleeve can either be on Lagerhörp, himself or on be attached to the moving shaft. In b ° it is particularly advantageous the sleeve shrunk on or pressed on.
In der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbeispiel veranschaulicht.In the drawing, the subject of the invention is in one embodiment illustrated.
Di,@ Welle i der Rollenelektrode einer Widerstandsnahtschweißmaschine hat an dem eincn Ende den Flansch 2, an dem die eigentliche, in der Zeichnung nicht veranschaulichte Rollenelektrode der Schweißmaschine befestigt ist. Auf der Welle i, die vorzugsweise aus Bronze besteht, ist durch Schrumpfen oder Pressen eine aus Stahl bestehende Hülse 3, die nach dem Schrumpfen oder Pressen eine Nachbearbeitung erfahren hat, angeordnet. Der Lagerkörper .I besteht wiederum aus Bronze und ist mit Schmiernuten 5 versehen. Die Schmierung wird diesen Nuten 5 mittels der Buchse 6 zugeführt.Di, @ shaft i of the roller electrode of a resistance seam welding machine has the flange 2 at one end, but not the actual one in the drawing illustrated roller electrode is attached to the welding machine. On the wave i, which is preferably made of bronze, is made of by shrinking or pressing Steel existing sleeve 3 which, after shrinking or pressing, requires post-processing has learned, arranged. The bearing body .I in turn consists of bronze and is provided with lubrication grooves 5. The grooves 5 are lubricated by means of the bushing 6 supplied.
