Description

Kugellaufkränze bei Baggern, Absetzern, Abraumförderbrücken u. dgl. werden mit Öl oder Fett oder einem Fett-Öl-Gemisch geschmiert, um ihren Verschleiß möglichst gering zu halten. Trotzdem tritt ein Abreiben feinster Metallteilchen der aufeinander abrollenden Teile in den Kugellaufkränzen auf, die den Verschleiß der Kugellaufkränze erheblich steigern und zu einer vorzeitigen Erneuerung zwingen. Beim Wechsel des Schmier= mäterials verbleiben nämlich die abgeriebenen Teilchen in den Kugellaufkränzen; wesentlich anders liegen die Verhältnisse auch dann nicht, wenn eine Umlaufschmierung vorgesehen wird. Andererseits ist der Ausbau der Kugellaufkränze bei schweren Geräten, wie Baggern, Absetzern, Abraumförderbrücken, schon an sich mit hohen Kosten verbunden, die noch durch den Betriebsausfall um das Mehrfache erhöht werden.Ball treads on excavators, skimmers, overburden conveyor bridges and the like. are lubricated with oil or grease or a mixture of grease and oil to prevent wear and tear to be kept as low as possible. Even so, the finest metal particles are rubbed off the parts rolling on each other in the ball races, which cause wear increase the number of ball races considerably and force them to replace them prematurely. When the lubricant is changed, the abraded particles remain in the ball rims; The circumstances are not significantly different even if if circulating lubrication is provided. On the other hand, there is the expansion of the ball races with heavy equipment such as excavators, skimmers, overburden conveyor bridges, in itself associated with high costs, which are multiplied by the downtime increase.

Um diese Nachteile zu beseitigen, wird erfindungsgemäß vorgeschlagen, in den Kugellaufkränzen zwischen den Kugeln starke permanente Magnete oder Elektromagnete vorzusehen, welche die abgeriebenen feinen Metallteilchen anziehen und auf diese Weise unschädlich machen. Die Lebensdauer der Kugellaufkränze wird dadurch ganz wesentlich erhöht.In order to eliminate these disadvantages, it is proposed according to the invention that strong permanent magnets or electromagnets in the ball rims between the balls provide which attract the abraded fine metal particles and onto them Wise harmless. The service life of the ball races is thereby fully significantly increased.

Die feinen Metallteilchen können nach einem weiteren Erfindungsgedanken dadurch von den Magneten entfernt werden, daß in den Kugellaufkränzen Öffnungen für Abstreifer vorgesehen werden.The fine metal particles can according to a further concept of the invention be removed from the magnets by making openings in the ball rims for scrapers.

In der Zeichnung ist das Wesen der Erfindung schematisch dargestellt.The essence of the invention is shown schematically in the drawing.

Abb. I zeigt den Querschnitt durch einen Kugel-Laufkranz nach der Erfindung; Abb. 2 zeigt einen Längsschnitt nach der Linie I-I der Abb. I.Fig. I shows the cross section through a ball-raceway according to the Invention; Fig. 2 shows a longitudinal section along the line I-I of Fig. I.

In der Kugellaufbahn I, in welcher Öl vorgesehen ist, sind zwischen den Kugeln starke Magnete 2 angeordnet. Selbstverständlich kann die Erfindung auch bei Wälzlagern u. dgl. in gleicher Weise Anwendung finden. Mit 3 ist die Dichtung der beiden Laufkranzhälften bezeichnet.In the ball track I, in which oil is provided, are between the balls strong magnets 2 arranged. Of course, the invention can also are used in the same way in roller bearings and the like. With 3 is the seal of the two tread halves.
