Abstract
Description
Die Erfindung betrifft ein Verfahren zum Schmieren und Kühlen einer Lageranordnung, die eine in einem flüssigen Metall laufende Rolle lagert. Des weiteren betrifft die Erfindung eine Lageranordnung.The The invention relates to a method for lubricating and cooling a Bearing assembly comprising a roller running in a liquid metal outsourced. Furthermore, the invention relates to a bearing assembly.
Aus
der
Generell stellt die Lagerung von Rollen, die in einem Schmelztauchgefäß laufen, eine problematische Aufgabe dar.As a general rule provides the storage of rolls that run in a hot dipping pot, a problematic task.
Aus der WO 03/019066 A1 ist ein Verfahren zum Schmieren und Kühlen einer Lageranordnung beschrieben, wobei das Schmieren von Schmierstellen mit einer Schmierstoff-Minimalmenge erfolgt, und wobei der Schmierstoff mit einem gasförmigen Trägermedium zu einem Schmierstoffnebel vermischt und dieser dann der Schmierstelle zugeführt wird.Out WO 03/019066 A1 is a method for lubricating and cooling a Bearing arrangement described, wherein the lubrication of lubrication points with a lubricant minimum amount, and wherein the lubricant with a gaseous transfer medium mixed into a lubricant mist and then the lubrication point supplied becomes.
Wälzlager, die bei hohen Umgebungstemperaturen arbeiten müssen, können hiermit sowohl gekühlt als auch geschmiert werden. Ein besonders kritischer Anwendungsfall ist derjenige, bei dem Rollen in flüssigen Metallen gelagert werden müssen. Bei Feuerverzinkungsanlagen muss meist eine Metallband-Umlenkrolle in flüssigem Zink laufen, wozu die beidseitig der Rolle angeordneten Lageranordnungen unterhalb des Badpegels liegen und in das flüssige Zink eintauchen.Roller bearing, which have to work at high ambient temperatures can hereby both cooled as also be lubricated. A particularly critical application is the one where rolls are stored in liquid metals have to. In hot-dip galvanizing systems usually has a metal belt pulley in liquid zinc run, including the arranged on both sides of the roll bearing assemblies lie below the bath level and immerse in the liquid zinc.
Es ist bekannt, in diesem Falle die oben genannte Lösung einzusetzen, um durch Zufuhr von Druckluft eine Sperrwirkung zu erzielen. Flüssiges Zink, das versucht, in das Lager einzudringen, wird durch die Sperrluft hiervon abgehalten. Dabei kühlt der zugeführte Medienstrom auch das Lager.It is known to use in this case, the above solution by Supply of compressed air to achieve a blocking effect. Liquid zinc, trying to penetrate the camp is by the air barrier held thereof. It cools the supplied Media stream also the warehouse.

Trotz der vorbekannten Lösung ist es schwierig, langfristig die zuverlässige Abschirmung des Lagers sicherzustellen und nicht nur das Eindringen von Schmelze in das Lager zu verhindern, sondern das Lager auch zuverlässig zu kühlen und zu schmieren. Dies gilt insbesondere dann, wenn Temperaturen bis zu 400 °C dauerhaft ausgehalten werden müssen. Ölnebel-Schmierungen geraten dabei an ihre Grenzen, so dass die Funktionsfähigkeit der Lageranordnung nicht unbedingt langfristig garantiert werden kann.In spite of the previously known solution it is difficult in the long term to provide reliable shielding of the bearing ensure and not only the penetration of melt in the To prevent bearing, but also the bearing reliable too cool and to lubricate. This is especially true when temperatures up to 400 ° C must be endured permanently. Oil mist lubrication get to their limits, so that the functionality The bearing arrangement is not necessarily guaranteed in the long term can.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine zugehörige Lageranordnung der eingangs genannten Art so weiterzubilden, dass auch bei lang anhaltender hoher Temperaturbelastung der Lageranordnung eine stabile Schmierung und Kühlung erzielt werden kann, so dass der Dauereinsatz bei Betriebstemperaturen bis zu 400 °C und mehr sichergestellt werden kann.Of the Invention is therefore the object of a method and a associated Bearing arrangement of the type mentioned in such a way that even with long-lasting high temperature load of the bearing assembly a stable lubrication and cooling can be achieved, so that the continuous use at operating temperatures up to 400 ° C and more can be ensured.
Die Lösung dieser Aufgabe durch die Erfindung ist verfahrensgemäß dadurch gekennzeichnet, dass ein mit Schmierstoff versetztes gasförmiges Medium mindestens einer Lagerstelle der Lageranordnung mit Überdruck zugeführt wird, wobei das gasförmige Medium Luft oder ein Inertgas ist, in die bzw. in das Schmierstoff in Pulverform eingebracht wird und wobei der Mengenstrom an mit Schmierstoff versetztem gasförmigen Medium und/oder dessen Druck so bemessen wird, dass der mit Schmierstoff versetzte Medienstrom als Sperrgas bzw. Sperrluft an der Lagerstelle wirkt.The solution This object by the invention is according to the method thereby in that a lubricant-added gaseous medium at least one bearing of the bearing assembly with positive pressure supplied being, being the gaseous Medium air or an inert gas is in or into the lubricant is introduced in powder form and wherein the flow rate with Lubricant added gaseous Medium and / or its pressure is measured so that the offset with lubricant Media flow acts as a sealing gas or sealing air at the bearing point.
Der Luft bzw. dem Gas wird also Schmierstoffpulver zugegeben, wobei es sich besonders bewährt hat, wenn es sich bei dem Pulver um solches aus Metallsulfid (z.B. MoS2) oder aus Graphit handelt.Thus, lubricant powder is added to the air or the gas, and it has proved particularly useful if the powder is such of metal sulfide (eg MoS 2 ) or of graphite.
Möglich ist auch der Einsatz von CaF2 (Calcium-Fluorit oder Flussspat) oder Cr2O3 (Chromoxid).It is also possible to use CaF 2 (calcium fluorite or fluorspar) or Cr 2 O 3 (chromium oxide).
Die Partikelgröße des Pulvers liegt bevorzugt zwischen 0,1 μm und 50 μm.The Particle size of the powder is preferably between 0.1 microns and 50 μm.
Dabei ist insbesondere vorgesehen, dass das mit Schmierstoff versetzte gasförmige Medium frei von flüssigen Partikeln ist. Der Luft bzw. dem Stickstoff ist in diesem speziellen Fall also ausschließlich Schmierstoffpulver zugesetzt.there is provided in particular that the offset with lubricant gaseous Medium free of liquid Particles is. The air or the nitrogen is in this special Case exclusively Added lubricant powder.
Die Lageranordnung einer unter hoher thermischer Belastung stehenden Anlage, nämlich zur Lagerung einer in einem flüssigen Metall laufenden Rolle, die eine Einrichtung zur Schmierung und Kühlung mindestens einer Lagerstelle aufweist, ist erfindungsgemäß dadurch gekennzeichnet, dass die Einrichtung zur Schmierung und Kühlung Mittel zum Unter-Druck-Setzen von Luft oder Stickstoff und Mittel zum Zugeben eines Schmierstoffs in Pulverform in die Luft bzw. in das Inertgas aufweist.The bearing assembly of a standing under high thermal stress system, namely the Storage of a running in a liquid metal roller having a means for lubricating and cooling at least one bearing, according to the invention is characterized in that the means for lubricating and cooling means for pressurizing air or nitrogen and means for adding a lubricant in powder form in the air or in the inert gas.
Die Einrichtung weist bevorzugt einen Luftkompressor auf. Ferner hat sie einen geeigneten Pulverförderer.The Device preferably has an air compressor. Further has Make a suitable powder conveyor.
Das Erfindungskonzept zielt also darauf ab, dass pulverförmiger Trockenschmierstoff dem gasförmigen Kühlmedium zur Schmierung des Wälzlagers beigegeben bzw. zugeführt wird.The The concept of the invention thus aims to ensure that powdered dry lubricant the gaseous cooling medium for lubrication of the rolling bearing added or fed becomes.

Bei der vorliegenden Lageranwendung bei hoher Umgebungstemperatur wird also durch Abkapselung der Lagerstelle mittels des gasförmigen Mediums ein stabiler Betriebszustand erreicht, indem der Sperrluft bzw. dem Sperrgas pulverförmiges Schmiermittel beigegeben wird. Hierdurch wird eine Minimalschmierung bei ausreichender Kühlwirkung erreicht, so dass die Lageranordnung eine hinreichende Lebensdauer erreicht.at the present bearing application at high ambient temperature So by encapsulation of the bearing by means of the gaseous medium achieved a stable operating condition by the sealing air or the sealing gas powdered lubricant is added. As a result, a minimum lubrication with sufficient Cooling effect achieved, so that the bearing assembly reaches a sufficient life.
