Abstract
Description
Die Erfindung betrifft eine Lagerungseinheit für hohe Drehzahlen, insbesondere für Spinnrotoren einer Offenend-Spinnvorrichtung, mit einem Lagergehäuse, in dem eine mittels Wälzlagern gelagerte, mit beiden Enden aus dem Lagergehäuse herausragende Welle angeordnet ist, und bei der das Lagergehäuse eine radiale Nachschmieröffnung aufweist.The The invention relates to a bearing unit for high speeds, in particular for spinning rotors of an open-end spinning device, with a bearing housing, in which one by means of rolling bearings mounted, with both ends protruding from the bearing housing Shaft is arranged, and in which the bearing housing a has radial relubrication.
Eine derartige Lagerungseinheit wird hauptsächlich für Offenend-Spinnvorrichtungen verwendet. Auf der Welle der Lagerungseinheit wird auf dem einen Ende direkt ein Spinnrotor angebracht, der mit Rotordrehzahlen in der Größenordnung von 100.000 min–1 rotiert. Der Spinnrotor wird von einem über das gegenüberliegende Ende der Welle laufenden Tangentialriemen angetrieben. Bei der Herstellung wird die Lagerungseinheit mit einem hochwertige Wälzlagerfett gefettet. Während des Betriebs werden die Wälzlager in der Lagerungseinheit über die Nachschmieröffnung nachgeschmiert. Bei der Nachschmierung wird lediglich Öl in das Lagergehäuse eingebracht, mit dem man das im Fett verbrauchte Öl ersetzt.Such a storage unit is mainly used for open-end spinning devices. On the shaft of the bearing unit, a spinning rotor is mounted directly on one end, which rotates at rotor speeds of the order of 100,000 min -1 . The spinning rotor is driven by a tangential belt passing over the opposite end of the shaft. During production, the bearing unit is greased with a high-quality roller bearing grease. During operation, the rolling bearings in the bearing unit are relubricated via the relubrication opening. When re-lubricating only oil is introduced into the bearing housing, with which one replaces the oil used in the grease.
Eine
Lagerungseinheit der eingangs genannten Art ist durch die
Der Erfindung liegt die Aufgabe zu Grunde, einen Lagerungseinheit zu schaffen, bei der die Ölverteilung innerhalb des Lagergehäuses ausgehend von einer Nachschmieröffnung verbessert ist.Of the Invention is based on the object to a storage unit create, at which the oil distribution within the bearing housing is improved starting from a relubrication opening.
Die Aufgabe wird dadurch gelöst, dass die Welle wenigstens einen konischen Bereich aufweist, dessen Durchmesser sich ausgehend von der Nachschmieröffnung in Richtung eines Wälzlagers vergrößert.The Task is solved in that the shaft at least has a conical portion whose diameter is starting from the relubrication opening in the direction of a rolling bearing increased.
Aufgrund der Fliehkraft, die das über die Nachschmieröffnung auf die Welle gelangte Öl erfährt, wird das Öl in dem konischen Bereich in Richtung des größten Durchmessers transportiert und dem Fettdepot des betreffenden Wälzlagers zugeführt.by virtue of the centrifugal force, that via the relubrication The oil that has reached the shaft experiences the oil in the conical area towards the largest Diameter transported and the grease deposit of the bearing in question fed.
Der
Transport von Schmiermittel in einer Lagerungseinheit ist an sich
durch die
Durch den konischen Bereich der Welle lässt sich außerdem dem Effekt entgegenwirken, dass das Schmiermittel in der Lagerungseinheit durch den den Spinnrotor umgebenden Unterdruck das Bestreben hat, von dem dem Spinnrotor abgewandten Wälzlager abgezogen zu werden. Die Transportwirkung des konischen Bereichs wirkt diesem Unterdruck entgegen.By the conical portion of the shaft can also be counteract the effect that the lubricant in the storage unit through the negative pressure surrounding the spinning rotor, deducted from the spinning rotor facing away from rolling bearings to become. The transport effect of the conical area acts this Negative pressure.
In Ausgestaltung der Erfindung ist es vorteilhaft, dass der konische Bereich mit seinem größten Durchmesser an einer sprunghaften Durchmesserverkleinerung der Welle endet. Die sprunghafte Durchmesserverkleinerung befindet sich dicht neben einem Wälzlager. Das durch den konischen Bereich transportierte Öl wird am größten Durchmesser abgeschleudert und verteilt sich dadurch gut an dem Wälzlager.In Embodiment of the invention, it is advantageous that the conical Area with its largest diameter at one sudden diameter reduction of the shaft ends. The sudden diameter reduction is close to a rolling bearing. That by the conical area transported oil becomes the largest Thrown off diameter and thus spread well on the rolling bearing.
Es kann vorteilhaft sein, dass dem größten Durchmesser des konischen Bereichs eine Auffangrille im Lagergehäuse zugeordnet ist. Aus der Auffangrille kann abgeschleudertes Öl, das noch nicht zu den Wälzkörpern gelangt ist, teilweise gesammelt werden und wieder auf die Welle abtropfen und so doch noch zu den Wälzkörpern gelangen.It may be beneficial to the largest diameter the conical area a collecting groove in the bearing housing assigned. From the collecting groove can be thrown off oil, that has not yet reached the rolling elements, be partially collected and drain again on the shaft and but still get to the rolling elements.
Falls die Nachschmieröffnung einen größeren Abstand zu beiden Wälzlagern aufweist, kann es vorteilhaft sein, dass die Welle zwei konische Bereiche aufweist, deren Durchmesser sich ausgehend von der Nachschmieröffnung in Richtung beider Wälzlager vergrößern. Die beiden konischen Bereiche können dabei durchaus unterschiedliche Neigungen aufweisen, deren Größe jeweils an die benötigte Transportwirkung angepasst sein kann. Der konische Bereich mit dem sich zum Spinnrotor hin vergrößernden Durchmesser kann eine geringere Neigung haben als der andere konische Bereich.If the relubrication opening a larger Distance to both bearings, it may be advantageous be that the shaft has two conical areas whose diameter starting from the relubrication opening in the direction of both rolling bearings enlarge. The two conical areas can have quite different inclinations, their size each adapted to the required transport effect can. The conical area with the enlarging towards the spinning rotor Diameter may have a lower inclination than the other conical one Area.
Aufgrund der hohen Drehzahlen der Welle ist es ausreichend, wenn der Unterschied zwischen dem kleinsten Durchmesser und dem größten Durchmesser eines konischen Bereichs sehr klein ist und nur einige Zehntelmillimeter beträgt. Der Unterschied beträgt bevorzugt etwa drei bis fünf Zehntelmillimeter.by virtue of the high speed of the shaft, it is sufficient if the difference between the smallest diameter and the largest Diameter of a conical area is very small and only a few Tenths of a millimeter. The difference is prefers about three to five tenths of a millimeter.
