Description
Bei Wälzlagern hat der zugeführte Schmierstoff bekanntlich die Aufgabe, zwischen den sich relativ zueinander bewegenden Lagerteilen einen Schmierfilm zu bilden. Reibung und Verschleiß dieser Teile werden dadurch herabgesetzt, was in um so vollkommenerem Maße erzielt wird, je gleichmäßiger und nachhaltiger, die Schmierung ist.In the case of roller bearings, the lubricant supplied has the task, as is well known, between the relative to form a lubricating film on bearing parts moving towards one another. Friction and wear of these parts are thereby diminished, which is achieved in the more perfect measure, the more evenly and more sustainable, the lubrication is.
Bei der Wälzlagerschmierung ist dafür Sorge zu tragen, daß den Lagern genügend Schmierstoff zugeführt wird. Dieser Maßnahme bei der Schmierung kommt mit Rücksicht auf die ständig erhöhten Anforderungen an die Wälzlager eine immer größere Bedeutung zu. Vor allem ist dabei eine verläßliche Zuführung unverbrauchten Schmierstoffes in das Wälzlagerinnere sicherzustellen. Es hat sich hier als »5 besonders vorteilhaft erwiesen, den Käfig des Wälzlagers mit zusätzlichen Teilen zu versehen, die diese Aufgabe übernehmen.In the case of roller bearing lubrication, care must be taken to ensure that sufficient lubricant is supplied to the bearings will. This measure of lubrication takes into account the constantly increasing demands to the rolling bearings is becoming increasingly important. Above all, there is a reliable one Ensure supply of unused lubricant into the interior of the roller bearing. It has proven to be the »5th proved particularly advantageous to provide the cage of the rolling bearing with additional parts that this Assume task.
,*$[ Es ist bei Gleitlagerschmierungen bereits bekannt, üfiurch einen an der Welle vorgesehenen Auflaufnocken eine Schmiermittelpumpe zu betätigen, die das Lager mit Schmiermittel versorgt. Dabei ist im Schmiermittelsumpf des Lagergehäuses eine vollständige Druckpumpe angeordnet, die über einen oder mehrere die Lagerschale durchsetzende Kanäle den Schmierstoff an die Lagerstellen führt. Eine derartige Vorrichtung ist jedoch aufwendig und läßt sich nur dort anwenden, wo genügend Raum zur Verfügung steht., * $ [It is already known for plain bearing lubrication üfiby a stop cam provided on the shaft operate a lubricant pump that supplies the bearing with lubricant. It is in the lubricant sump of the bearing housing a complete pressure pump is arranged, which has one or more The channels penetrating the bearing shell guides the lubricant to the bearing points. Such a device However, it is expensive and can only be used where there is enough space available.
Die geschilderten Nachteile sind durch die Erfindung bei einer Vorrichtung zur Wälzlagerschmierung dadurch behoben, daß erfindungsgemäß ein Käfig mit einem Auflaufnocken ausgebildet ist, der eine im Außenring des Wälzlagers angeordnete Schmiermittelpumpe betätigt. Die Pumpe besteht vorteilhaft aus einem federbelasteten, mit einer Längsbohrung versehenen Kolben. Die Anordnung des Auflaufnockens am Käfig ist weniger aufwendig als die Ausbildung der Welle mit einem Exzenter. Die Unterbringung der Pumpe im Wälzlageraußenring wirkt darüber hinaus raumsparend, und schließlich ist auch die erfindungsgemäße Ausbildung der Pumpe selbst einfacher und billiger als bei der bekannten Gleitlagerschmierung. The described disadvantages are due to the invention in a device for rolling bearing lubrication remedied by the fact that according to the invention a cage is formed with a run-up cam, which is one in the Outer ring of the rolling bearing arranged lubricant pump operated. The pump is advantageous from a spring-loaded piston provided with a longitudinal bore. The arrangement of the approach cam on the cage is less expensive than the formation of the shaft with an eccentric. The shelter the pump in the roller bearing outer ring also saves space, and finally, the inventive Formation of the pump itself easier and cheaper than with the known sliding bearing lubrication.
Die Erfindung ist in der nachstehenden Beschreibung an Hand der Zeichnung beispielhaft erläutert. Als Ausführungsbeispiel ist ein Radialpendelrollenlager mit geteiltem Massivkäig gewählt.The invention is explained by way of example in the following description with reference to the drawing. as The embodiment selected is a radial spherical roller bearing with a split solid cage.

Fig. 2 eine Seitenansicht des Auflaufnockens.Fig. 2 is a side view of the run-up cam.
In Fig. 1 ist am mittleren Teil des Käfigs 11 ein Auflaufnocken 12 angebracht. Diese Nocken 12 sind an jeder Käfighälfte angebracht und führen beim Umlaufen des Käfigs in Verbindung mit der Pumpvorrichtung 14 eine Pumpwirkung auf den im Behälter 13 anstehenden Schmierstoff herbei, den sie durch die Bohrung im Innenring 15 des Lagers in dessen Inneres hineinbeför.dern. Fig. 2 zeigt eine Seitenansicht einer erfindungsgemäßen Käfighälfte 11 mit dem angearbeiteten Nocken 12.In Fig. 1, a stop cam 12 is attached to the central part of the cage 11. These cams 12 are attached to each cage half and lead when rotating the cage in connection with the pumping device 14 brings about a pumping effect on the lubricant in the container 13, which they through the bore in the inner ring 15 of the bearing into the interior of it. Fig. 2 shows a Side view of a cage half 11 according to the invention with the attached cam 12.
Die Maßnahmen nach der Erfindung sind nicht auf die Anwendung bei einer zweireihigen Wälzlagerausführung beschränkt, sie können vielmehr bei allen Wälzlagertypen benutzt werden und führen dabei stets eine richtige Dosierung der erforderlichen Schmierstoffmenge herbei. Ein unzulässiger Verschleiß des Lagers durch zuwenig Schmierstoff wird mit den Vorkehrungen nach der Erfindung also ebenso vermieden wie eine zu starke Lagererwärmung durch zu reichliche Schmierstoffmengen.The measures according to the invention are not applicable to a double-row rolling bearing design limited, they can rather be used with all types of rolling bearings and lead thereby always ensures the correct dosage of the required amount of lubricant. Inadmissible wear of the bearing due to insufficient lubricant is the same with the precautions according to the invention avoided such as excessive warming of the bearings due to excessive quantities of lubricant.
