Description
sich drehenden Wellerotating shaft
Die Erfindung bezweckt, die bisher übliche Abdichtung einer in einer Stopfbuchse sich drehenden Welle, insbesondere für Klein-Kältemaschinen vollkommen gasdicht zu gestalten. Das Neue besteht darin, daß die Welle (zwecks Verteilung eines abdichtenden Ölschleiers) in ihrer Längsrichtung zwangsläufig hin und her bewegt wird. Wie die Längsbewegung der Welle erfolgt, ist für die ίο Erfindung gleichgültig. Es ist bekannt, daß Wellen von Elektromotoren mit einem kleinen Längsspielraum ausgeführt werden, damit sich die elektromagnetischen Wirkungen nach beiden Längsrichtungen hemmungslos auf den Rotor auswirken können und gleichzeitig eine gleichmäßige Abnutzung des Kummutators oder Kollektors sowie eine wirksame Verteilung des Schmieröles in den Lagerschalen erfolgt. Dieses Spielen der Welle erfolgt aber hier nicht zwangsläufig, sondern die Welle wird, wenn sie sich in der einen Richtung verschoben hat, durch einen Anschlag gehemmt und erhält so einen Anstoß, sich in der entgegengesetzten Richtung zu bewegen. Dadurch, daß die Welle gemäß der Erfindung zwangsläufig hin und her bewegt wird, ist ständig ein dünner Ölschleier zwischen Welle und Packungsmaterial vorhanden, der die Welle gasdicht abschließt. Das Packungsmaterial kann so fest angezogen werden, daß nur ein hauchartiger Ölschleier entsteht, der vollkommen zur Abdichtung genügt und ein Festbrennen der Welle verhütet. In der Zeichnung ist ein Ausführungsbeispiel dargestellt, α ist ein Stopfbüchsgehäuse bekannter Art, das gegen einen Gasraum durch eine Flanschdichtung abgedichtet ist, b eine sich drehende Welle, die im Gasraum eine Kurbel, ein Exzenter oder einen Schleuderkreisel treibt; c sind Dichtungsringe aus Packungsmaterial, die durch Anziehen der Stopfbüchsbrille e an die Welle - angepreßt werden; d ist ein ölkammerring, der die Anzahl Dichtungsringe in zwei Teile teilt und eine mittlere Ölkammer bildet, so daß die innere Packung die Welle gegen den Gasraum und die äußere nur gegen den ölraum abzudichten hat; f ist eine Vorrichtung zur " Verschiebung der Welle, die jedoch auch vom Gasraum aus, beispielsweise durch Gasdruck oder Preßöl erfolgen kann.The aim of the invention is to make the hitherto customary sealing of a shaft rotating in a stuffing box, in particular for small refrigerating machines, completely gas-tight. The novelty is that the shaft (for the purpose of distributing a sealing oil curtain) is inevitably moved back and forth in its longitudinal direction. How the longitudinal movement of the shaft takes place is irrelevant to the ίο invention. It is known that shafts of electric motors are designed with a small longitudinal clearance so that the electromagnetic effects can unrestrainedly affect the rotor in both longitudinal directions and at the same time there is an even wear of the commutator or collector and an effective distribution of the lubricating oil in the bearing shells. However, this play of the wave does not inevitably take place here, but rather the wave, if it has shifted in one direction, is inhibited by a stop and thus receives an impetus to move in the opposite direction. Because the shaft is inevitably moved back and forth according to the invention, there is always a thin oil veil between the shaft and the packing material, which seals the shaft in a gas-tight manner. The packing material can be tightened so tightly that only a puff-like oil veil is created, which is completely sufficient for sealing and prevents the shaft from sticking. In the drawing, an embodiment is shown, α is a stuffing box housing of known type, which is sealed against a gas space by a flange seal, b a rotating shaft that drives a crank, an eccentric or a centrifugal gyro in the gas space; c are sealing rings made of packing material, which are pressed against the shaft by tightening the gland follower e; d is an oil chamber ring which divides the number of sealing rings into two parts and forms a central oil chamber so that the inner packing has to seal the shaft against the gas space and the outer packing only against the oil space; f is a device for "shifting the shaft, which can, however, also take place from the gas space, for example by gas pressure or press oil.
