Description

Schutzvorrichtung für Lager, die in zerstörende Gase oder Dämpfe führenden Leitungen angeordnet sind Es hat sich gezeigt, daß bei Lagern, die in Leitungen, angeordnet sind, durch welche aggressive Gase oder Dämpfe geführt werden, sowohl die metallischen Bestandteile des Lagers als auch insbesondere das im Lager befindliche Schmiermittel häufig angegriffen werden. Durch die erfindungsgemäße Vorrichtung soll dies verhindert werden.Protective device for bearings that lead into destructive gases or vapors Lines are arranged It has been shown that in bearings that are in lines, are arranged through which aggressive gases or vapors are passed, both the metallic components of the bearing and, in particular, that in the bearing Lubricants are often attacked. By the device according to the invention should this be prevented.

Die erfindungsgemäße Vorrichtung besteht aus einem Hohlkörper, der auf der Welle in Strömungsrichtung vor dem Lager angeordnet ist. Der Hohlkörper ist gegen das Lager zu offen und wird vorzugsweise möglichst nahe am Lager angebracht. Er weist einen Durchmesser auf, der den des Lagers möglichst nur um ein Geringes überschreitet. Die Form des Hohlkörpers kann die eines Abschnittes eines Torpedos oder Tropfens, eines Trichters, einer Glocke o. dgl. sein. In den Hohlraum des Hohlkörpers mündet eine-Leitung, die ins Freie geführt wird. In der Zeichnüng ist eine beispielsweise Ausführungsform des erfindungsgemäßen Lagerschutzes dargestellt. i.. ist die Welle, die die Ventilatorflüge1 2 trägt. 3 ist das zu schützende Lager und 4 der erfindungsgemäße Hohlkörper mit der Zuleitung 5. Das Ganze ist innerhalb des Rohres 6 gelegen.The device according to the invention consists of a hollow body which is arranged on the shaft in the direction of flow in front of the bearing. The hollow body is too open towards the bearing and is preferably attached as close as possible to the bearing. It has a diameter which, if possible, only slightly exceeds that of the bearing. The shape of the hollow body can be that of a section of a torpedo or drop, a funnel, a bell or the like. A line which is led outside opens into the cavity of the hollow body. In the drawing, an example embodiment of the bearing protection according to the invention is shown. i .. is the shaft that carries the fan flights1 2. 3 is the bearing to be protected and 4 is the hollow body according to the invention with the supply line 5. The whole is located within the tube 6 .

Durch die Ventilatorflügel wird das zu befördernde Gas in der Pfeilrichtung vorwärts getrieben, streicht am Hohlkörrper entlang und bewirkt in dessen Innern das Entstehen eines Unterdruckes. Für eine Gasgeschwindigkeit von beispielsweise 5 m pro Sekunde konnte im Innern des Hohlkörpers ein Unterdruck von 1:2 inm WS festgestellt werden. Durch. die nach außen mündende Leitung 5 wird in das Innere des Hohlkörpers frische Luft angesaugt, die nun aus dem Hohlraum ausströmt und einen Luftsack bildet, der das Lager umhüllt und die aggressiven Gase fernhält. Es ist daher, wie auch die Praxis ergeben hat, nicht nur die dem Schutz zugewendete Seite des Lagers geschützt, sondern auch die abgewendete. Ein Einwirken der Gase, insbesondere auf das Lagerfett, ist daher ausgeschlossen.The gas to be conveyed is driven forward in the direction of the arrow by the fan blades, brushes along the hollow body and causes a negative pressure to develop inside. For a gas velocity of, for example, 5 m per second, a negative pressure of 1: 2 in water could be determined inside the hollow body. By. the outwardly opening line 5 is sucked into the interior of the hollow body fresh air, which now flows out of the cavity and forms an air bag that envelops the bearing and keeps the aggressive gases away. As practice has also shown, it is therefore not only the side of the bearing facing the protection that is protected, but also the side facing away. An effect of the gases, in particular on the bearing grease, is therefore excluded.

Anstatt die Leitung 5 ins Freie zu führen, kann durch sie auch ein beliebiges anderes.` Schutzgas zugeführt werden.Instead of leading the line 5 to the outside, a any other protective gas can be supplied.

Der erfindungsgemäße Lagerschutz kann z. B. für Lufttrockenschränke, Abzugsschächte u. dgl. verwendet werden.The bearing protection according to the invention can, for. B. for air drying cabinets, Discharge shafts and the like can be used.

Die erfindungsgernäße Schutzvorrichtung ist selbstverständlich nicht nur für Lager von Wellen geeignet, die Ventilatorflügel tragen, sie kann vielmehr für den Schutz von Lagern von Wellen beliebigen Zweckes verwendet werden. Notwendig ist nur, daß ein auf beliebige Weise erzeugter Gasstrom nicht allzu kleiner Geschwindigkeit an der Schutzvorrichtung vorbeiströmt.The protection device according to the invention is of course not only suitable for bearings of shafts that carry fan blades, it can rather can be used for the protection of bearings of shafts for any purpose. Necessary is just that a gas flow generated in any way is not too slow in speed flows past the protective device.

Es ist bekannt, Motoren, deren Achsen Ventilatorflügel tragen und die in Leitungen angeordnet sind, die heiße Gase führen, dadurch kühl zu halten, daß man die Motoren in geschlossene Torpedos einkapselt, die mit der Außenluft durch ein Rohr in Verbindung stehen. Solche allseitig geschlossenen, fest gelagerten Schutzhüllen sind nur bei in sich geschlossenen Aggregaten, wie eben .Motoren, möglich, nicht aber an durchgehenden Wellen, da sie in diesem Fall, uni die durchgesteckte, sich drehende Welle nicht zu an beiden Enden kreisförmige "Schlitze haben müssen, so daß die heiße Luft in das Innere der Schutzhülle eindringen würde.It is known motors whose axes carry fan blades and which are arranged in pipes that carry hot gases, thereby keeping them cool, that the motors are encapsulated in closed torpedoes that pass through with the outside air connect a pipe. Such fully enclosed, firmly mounted protective covers are only possible with self-contained units, such as motors, not but on continuous waves, since in this case, uni the stuck-through, they are rotating shaft doesn't have to have circular "slots at both ends, so." that the hot air would penetrate into the interior of the protective cover.
