Zur Verbesserung der Dichtwirkung wird angegeben, die Dichtring 11 mit den Innenringen 2, 3 zu verbinden und die Dichtlippen 12 gegen die Innenmäntel 10 von Rohren 8 anlaufen zu lassen, die zu diesem Zweck lösbar mit dem Außenring 1 verbunden sind. Zur Verbesserung der Dichtwirkung ist vorgesehen, dass jeder Dichtung 13 an ihrer axialen Innenseite ein Dichtschild 9 vorgeordnet ist, dessen freier Rand einen geringen radialen Abstand A zum Innenmantel 10 des Rohres 8 oder zum jeweiligen Innenring 2; 3 einhält. The invention relates to a double-row tapered roller bearing, which is designed as a large warehouse, and a wind turbine with such a tapered roller bearing. To improve the sealing effect is stated to connect the sealing ring 11 with the inner rings 2, 3 and to start the sealing lips 12 against the inner shells 10 of tubes 8, which are detachably connected to the outer ring 1 for this purpose. To improve the sealing effect is provided that each seal 13 is preceded on its axial inside a sealing plate 9, the free edge of a small radial distance A to the inner shell 10 of the tube 8 or the respective inner ring 2; 3 complies.
Description
Technisches GebietTechnical area
Die Erfindung betrifft ein zweireihiges Kegelrollenlager, das als ein Großlager ausgebildet ist, und eine Windenergieanlage mit einem derartigen Kegelrollenlager.The invention relates to a double-row tapered roller bearing, which is designed as a large warehouse, and a wind turbine with such a tapered roller bearing.
Großlager im Sinne dieser Anwendung sind alle Lager, die einen Außenringdurchmesser von wenigstens einem Meter haben.Large bearings in the sense of this application are all bearings that have an outer ring diameter of at least one meter.
Gattungsmäßige Großlager in der Form von zweireihigen Kegelrollenlagern sind etwa aus
Um möglichst dauerhaft ein reibungsfreies Abrollen der Wälzkörper zwischen den Lagerringen zu gewährleisten ist es üblich, eine Fettschmierung vorzusehen. Um das den Schmierstoff in den Ringraum zwischen den beiden Lagerringen dauerhaft zu halten, ist etwa aus
Reibt die Dichtlippe an dem Dichtflächen des Innenrings, kann nicht ausgeschlossen werden, dass sich im Laufe der Zeit durch den reibenden Kontakt die Dichtlippen in die Dichtflächen des Innenrings einarbeiten. Hat sich bereits die Dichtlippe in die Dichtfläche eingearbeitet und wird dann die Dichtung getauscht, ist ob der Einfurchung in der Dichtfläche die Dichtwirkung der getauschten Dichtung eher gering.Rubbing the sealing lip on the sealing surfaces of the inner ring, can not be ruled out that in the course of time by the rubbing contact the sealing lips in the sealing surfaces of the inner ring work. If the sealing lip has already been incorporated into the sealing surface and then the seal is replaced, the sealing effect of the replaced seal is rather small, if the penetration in the sealing surface is.
Daher liegt der Erfindung die Aufgabe zu Grunde ein verbessertes und servicefreundliches Dichtsystem für Großlager anzugeben.The invention is therefore based on the object to provide an improved and service-friendly sealing system for large storage.
Diese Aufgabe wird mit den in Anspruch 1 angegebenen Merkmalen gelöst. Das erfindungsgemäße Großlager ist als ein zweireihiges Kegelrollenlager ausgebildet, das einen Außenring aufweist, dessen Außendurchmesser mindestens 1 Meter, vorzugsweise mindestens 1,5 Meter, noch mehr bevorzugt 2 Meter beträgt sowie einen ersten Innenring und einen zweiten Innenring, der axial neben dem ersten Innenring angeordnet ist. Weiterhin weist das Kegelrollenlager einen ersten Satz von kegelig ausgebildeten ersten Wälzkörpern, die zwischen dem Außenring und dem ersten Innenring abrollen und einen zweiten Satz von kegelig ausgebildeten zweiten Wälzkörpern auf, die axial neben den ersten Wälzkörpern angeordnet sind und zwischen dem Außenring und dem zweiten Innenring abrollen, wobei der Ringraum zwischen dem Außenring und wenigstens einem Innenring mittels einer aus Dichtscheibe und Dichtlippe gebildeten Dichtung abgedichtet ist. Das Kegelrollengroßlager zeichnet sich dadurch aus, dass wenigstens ein Dichtungshalter vorgesehen, der mit dem Innenring verbunden ist und die Dichtscheibe drehfest festgelegt ist, dass ein Rohr vorgesehen ist, welches lösbar mit dem Außenring verbunden ist und diesen axial verlängert und dass die Dichtlippe am Innenmantel des Rohres dichtend anliegt.This object is achieved with the features specified in
Kommt es im Laufe der Zeit durch den reibenden Kontakt zwischen Dichtlippe und Innenmantel des Rohres zu einem Einarbeiten der Dichtlippe, dann nicht nur der Dichtring, sondern auch die Dichtfläche durch Austausch des Rohres in einfacher Weise erneuert werden, so dass nach dem Austausch von Dichtring und Rohr eine zuverlässige Dichtstelle zur Verfügung gestellt werden kann.If it comes in the course of time by the frictional contact between the sealing lip and inner casing of the tube to a working in of the sealing lip, then not only the sealing ring, but also the sealing surface are replaced by replacing the tube in a simple manner, so that after the replacement of sealing ring and Pipe a reliable sealing point can be provided.
Nach einer Ausführung der Erfindung kann vorgesehen sein, dass jedem Dichtungr an ihrer axialen Innenseite ein Dichtschild vorgeordnet ist, dessen freier Rand einen radialen Abstand A zum Innenmantel des Rohres oder dem Innenring einhält. Dadurch wird erreicht, dass die im Großlagerbereich erheblichen und von den drehenden Wälzkörpern bewegten Fett- bzw. Schmierstoffmengen nicht mehr ungehindert auf die elastischen Dichtringe auftreffen und deren Funktion beeinträchtigen.According to one embodiment of the invention can be provided that each Dichtr on its axial inside a sealing plate is arranged upstream, the free edge maintains a radial distance A to the inner surface of the tube or the inner ring. This ensures that the significant in the large storage area and moving from the rotating rolling elements grease or lubricant quantities no longer impinge unhindered on the elastic sealing rings and affect their function.
Erstreckt sich das jeweilige vom Innenring ausgehende Dichtschild in Richtung des Rohres, wird vom Dichtschild gleichzeitig eine Schulter bereitgestellt, welche eine Festlegung des Dichtrings am Innenring erleichert.If the respective sealing plate emanating from the inner ring extends in the direction of the tube, a shoulder is simultaneously provided by the sealing plate, which facilitates a fixing of the sealing ring on the inner ring.
Die Anzahl der Bauteile ist reduziert, wenn das jeweilige Dichtschild integraler Bestand des Rohres oder des Innenrings ist.The number of components is reduced if the respective sealing plate is an integral part of the tube or the inner ring.
