Description
Die Erfindung betrifft eine Schleifring-Dichtung für Wellen, insbesondere für Kompressions-Kältemaschinen. The invention relates to a slip ring seal for shafts, in particular for compression refrigeration machines.
Es ist zur flüssigkeitsdichten Lagerung von Wellen bekannt, auf der Welle eine Feder anzuordnen und einen mit derselben umlaufenden Schleifring, der durch die Kraft der Feder gegen einen zweiten Schleifring gepreßt wird, der mit dem Maschinengehäuse über einen an dem Wellenlagerkörper dicht befestigten elastischen Flanschteller verbunden ist, wobei der umlaufende Schleifring in einer Ringihülse angeordnet ist, die verschiebbar auf der Welle mittels eines Verdichtungsringes geführt ist. It is known for the liquid-tight storage of shafts to arrange a spring on the shaft and one with the same rotating slip ring, which is counteracted by the force of the spring a second slip ring is pressed, which is connected to the machine housing via one on the shaft bearing body tightly attached elastic flange plate is connected, with the circumferential slip ring is arranged in an annular sleeve which is slidably guided on the shaft by means of a compression ring.
Es ist weiterhin bereits bekannt, Schleifring-Dichtungen für Wellen, insbesondere von Kompressionskältemaschinen, so auszubilden, daß eine auf der Welle angeordnete Feder einen mit der Welle umlaufenden Schleifring gegen einen Schleifring anpreßt, der mit dem Maschinengehäuse über einen an dem Wellenkörper befestigten Flanschteller verbunden ist, wobei der umlaufende Scheifring in einer Ringhülse angeordnet ist, die verschiebbar auf der Welle mittels eines Dichtungsringes geführt ist.It is also already known to manufacture slip ring seals for shafts, in particular for compression refrigeration machines, in such a way that a spring arranged on the shaft has a slip ring rotating with the shaft against a slip ring which is connected to the machine housing via a flange plate attached to the shaft body is, wherein the circumferential sliding ring is arranged in an annular sleeve, which is displaceable is guided on the shaft by means of a sealing ring.
Die Erfindung sieht bei Schleifring-Dichtungen dieser Art vor, daß, was an sich bekannt ist, gegen einen Wellenbund wirkende Tellerfedern vorgesehen sind, die gegen die den umlaufenden Schleifring tragende Ringhülse wirken, und daß ferner auf der freien Wellenseite vor dem elastischen Flanschteller ein Abschlußdeckel vorgesehen ist, der mittels eines Dichtungsringes gegen die Welle abgedichtet ist. und einen Einlauf zum Einfüllen von Schmiermittel besitzt.The invention provides for slip ring seals of this type that what is known per se, against A shaft collar acting disc springs are provided which against the rotating slip ring bearing ring sleeve act, and that also on the free shaft side in front of the elastic flange plate an end cover is provided which is sealed against the shaft by means of a sealing ring. and has an inlet for filling in lubricant.
Der bei der erfindungsgemäßen Anordnung vor dem elastischen Flanschteller vorgesehene Schmierraum, der gegen die Welle durch den genannten Dichtungsring abgedichtet ist, bietet den Vorteil, daß bei einer mit Unterdruck arbeitenden Maschine Verschwinden von Schmiermitteln aus demThe lubrication space provided in front of the elastic flange plate in the arrangement according to the invention, which is sealed against the shaft by the aforementioned sealing ring, offers the advantage of that in a machine working with negative pressure disappearance of lubricants from the
eina
Dichtungsraum erkennen läßt, daß die Abdichtung der Welle nicht mehr gewährleistet ist; bei einer mit Überdruck arbeitenden Maschine würde ein Herauspressen von Schmiermitteln aus dem Dichtungsraum das gleiche anzeigen. Sealing chamber shows that the sealing of the shaft is no longer guaranteed; at one with Machine operating under positive pressure would indicate the same thing if lubricant was forced out of the sealing chamber.
Ein Ausführungsbeispiel einer erfindungsgemäßen Schleifring-Dichtung ist in der Figur im Schnitt dargestellt. Die in der Figur verwendeten Bezugszeichen (haben die folgende Bedeutung: - An embodiment of a slip ring seal according to the invention is shown in section in the figure shown. The reference symbols used in the figure (have the following meaning: -
2 ist die zu lagernde Welle, sie stellt die Kompressorwelle einer Kompressionskühlmaschine dar. ι ■ ist das Kompressorgehäuse. Die Welle 2 besitzt einen Wellenbund 2a. Auf der Welle 2 ist eine Anzahl von Tellerfedern 3 angeordnet, die in Richtung des Kompressorgehäuses gegen den Bund 2ß der Welle wirken. Mittels einer Gummiringdichtung 5 ist eine aus Stähl bestehende Ringhülse 4 auf der2 is the shaft to be supported, it represents the compressor shaft of a compression cooling machine. Ι ■ is the compressor housing. The shaft 2 has a shaft collar 2 a. On the shaft 2 a number of plate springs 3 are arranged, which act in the direction of the compressor housing against the collar 2 ß of the shaft. By means of a rubber ring seal 5 is made of steel ring sleeve 4 on the
Welle 2 axial verschiebbar angeordnet. In dieser Hülse ist der axial verschiebbare aus Sonderstahl bestehende Schleifring 6 eingebuchst. Seine Oberfläche ist plangeläppt.Shaft 2 arranged to be axially displaceable. In this sleeve, the axially displaceable one is made of special steel existing slip ring 6 buckled. Its surface is lapped flat.
Ein elastischer, ebenfalls aus Sonderstahl be-, stehender Flanschteller 9 ist mittels einer Dichtung 8 dicht an der vorderen Stirnfläche des das Lager bildenden Gehäuseteils 1 befestigt. An dem Flanschteller liegt der feststehende, zweckmäßig aus Sonderbronze bestehende Schleifring 7 an; er ist vorteilhafterweise an dem Flanschteller angelötet. An elastic flange plate 9, also made of special steel, is sealed against the front face of the das by means of a seal 8 Bearing forming housing part 1 attached. The fixed, functional one lies on the flange plate slip ring 7 made of special bronze; it is advantageously soldered to the flange plate.
Ein vorderer Abschlußdeckel 12 ist vorgesehen; eine der Dichtung 8 ähnliche Ringdichtung 10 ist zwischen Flanschteller 9 und Abschlußdeckel angeordnet. Der Abschlußdeckel 12 ist mittels eines Dichtungsringes 11 gegenüber". der Welle 2 abgedichtet. Im Abschluß deckel 12 ist ein Einlauf 13 vorgesehen, zum Einfüllen von Schmiermittel, welches die Versorgung der gleitenden Flächen der Schleifringe 6, 7 mit Schmiermittel bewirkt.A front end cover 12 is provided; a ring seal 10 similar to the seal 8 is arranged between the flange plate 9 and the cover plate. The cover plate 12 is sealed off from the shaft 2 by means of a sealing ring 11. In the final cover 12 an inlet 13 is provided for filling with lubricant, which brings about the supply of the sliding surfaces of the slip rings 6, 7 with lubricant.
