Description
Selbsttätige pneumatische Umlaufölung; insbesondere für Kugellager an stehenden Wellen Zur Schmierung von rasch laufenden Wellen ist es bekannt, Anordnungen zu treffen, die ohne Bedienung oder wenigstens ohne häufigen Zugriff arbeiten. Man verwendet hierfür entweder die Tropfölung, bei der das Öl aus einem Gefäß in jmstellbaren Zeitabständen in das Lager tropft und von dort wieder abfließt oder die selbsttätige Umlaufölung, bei der das Öl durch eine Pumpvorrichtung in das Lager befördert wird undvon dort wieder in die Pumpe zurückfällt.Automatic pneumatic circulating oil; especially for ball bearings on standing waves For the lubrication of fast running waves, it is known arrangements to meet who work without operation or at least without frequent access. Man either uses drip oiling, in which the oil is poured from a vessel into jmstellbaren At intervals it drips into the camp and flows off again from there or the automatic Circulating oiling, in which the oil is pumped into the bearing and from there falls back into the pump.
Bei der Tropfölung kann die in das Lager zu bringende Ölmenge sehr klein gehalten werden, so daß das Öl bis zum Eintritt ins Lager .nur wenig in Bewegung ist und keine Schaumbildung eintritt. Bei der Tropfölung ist es jedoch erforderlich, das Ölgefäß ziemlich häufig nachzufüllen, so daß leicht Verunreinigungen ins Öl geraten. Das gebrauchte Öl muß von Hand abgezogen werden.With drip oiling, the amount of oil to be brought into the bearing can be very high must be kept small so that the oil moves very little by the time it enters the bearing and no foaming occurs. With drip oiling, however, it is necessary to refill the oil compartment quite frequently, so that it is easy for impurities to get into the oil devices. The used oil must be drawn off by hand.
Bei der selbsttätigen Umlaufölung erfolgt zwar der Ölumlauf dauernd, so daß :eine Bedienung nicht erforderlich ist; das Öl wird hierbei jedoch in sehr lebhafte Bewegung versetzt und auch in zu großer Menge gefördert, so daß Schaumbildung eintritt.With automatic circulating oiling, the oil circulates continuously, so that: no operation is required; however, the oil is used in this very much lively movement and also promoted in too large a quantity, so that foam formation entry.
Diese Nachteile werden erfindungsgemäß dadurch vermieden, daß mittels eines Ventilators eine Luftdruckdifferenz zwischen dem Ölsumpf und der ölzuflußstelle am Lager erzeugt wird, durch die der Ölumlauf betätigt wird. Hierdurch wird erzielt, daß das Öl in seinem Lagerraum praktisch in Ruhe bleibt und daher nur ausgeruhtes Öl in die Steigleitung gelangt.These disadvantages are avoided according to the invention by means of of a fan, an air pressure difference between the oil sump and the oil inflow point is generated on the bearing, through which the oil circulation is operated. This achieves that the oil remains practically at rest in its storage room and therefore only rested Oil has entered the riser.
.In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Unter dem .normal eingebauten Kugellager i sitzt fest mit der Welle z verbunden ein Ventilator 3, der bei sich drehender Welle die unter dem La lger befindliche Luft in den Druckraum q. drückt. Hierdurch entsteht in dem über dem Kugellager sich befindenden Raum 5 eine Luftverdünnung. Die im Druckraum q. unter Spannung stehende Luft führt das Öl aus dem Behälter 6 wieder in die Steigleitung 7 nach oben, so daß das Öl oben in das Kugellager läuft. Das Öl, welches das Lager 'durchlaufen hat, wixd durch die Zentrifugalwirkung des Ventilators in den Druckraum 4 geschleudert, wo es sich an den Wänden absetzt, um wieder in den Behälter 6 zu rieseln. Da die Umlaufmenge mit der Drehzahl des Ventilators sich ändert, ist in der Steigleitung 7 eine Drossel 8 angeordnet, mittels der die Öldurchflußmenge eingestellt werden kann. Die Schmierung erfolgt also völlig selbsttätig. Die Lager selbst sind bei dieser Anordnung infolge der Saugwirkung nach oben und unten gegen Öldurehlaß vollkommen dicht.In the drawing, an embodiment of the invention is shown. Under the normally installed ball bearing i sits firmly connected to the shaft z a fan 3, which is located under the bearing when the shaft rotates Air in the pressure chamber q. presses. This creates in the one above the ball bearing located room 5 an air dilution. The in the pressure chamber q. under tension Air leads the oil from the container 6 back into the riser 7 upwards, see above that the oil runs up into the ball bearing. The oil that the camp 'pass through has, wixd thrown into the pressure chamber 4 by the centrifugal effect of the fan, where it settles on the walls to trickle back into the container 6. Since the Circulation amount changes with the speed of the fan is in the riser 7 a throttle 8 is arranged, by means of which the oil flow rate can be adjusted can. The lubrication is completely automatic. The camps themselves are at this arrangement due to the suction up and down against oil drain completely tight.
Die Anordnung kann mit .entsprechenden Abänderungen auch für liegende Wellen Verwendung finden.The arrangement can also be used for lying Use waves.
