Description

Abdichtung für eine Zahnkupplung Die Erfindung betrifft eine Abdichtung für Zahnkupplungen zum vorzugsweisen Einbau in Schnekkenpumpen, bei denen Rotor und Stator unterschiedliche Gangzahlen aufweisen.Seal for a tooth coupling The invention relates to a seal for tooth clutches for the preferred installation in screw pumps with rotors and stator have different numbers of turns.

Es sind bereits Abdichtungen für derartige Kupplungen bekannt, die als Faltenbälge oder Stulpen ausgebildet sind. Dieselben haben jedoch den Nachteil, daß sie im Strom des Fördergutes liegen und durch den Druck desselben deformiert werden und nicht ohne weiteres ausgetauscht werden können, wie es bei einer bekannten Ausführung der Fall ist. Bei einer weiteren bekannten Ausführung ist ein Metall-Gummi-Gelenk vorgesehen, das zwar #druckfest ausgebildet ist, jedoch den verzahnten Teil der Kupplung nicht mit abdichtet, wodurch der Zutritt von Fördergut in den inneren kugeligen Teil erfolgen kann. Auch muß bei derartigen Abdichtungen bei einer Auswechslung derselben ein großer Teil der Kupplung ausgebaut und wieder durch Kleben oder Vulkanisieren miteinander verbunden werden.There are already known seals for such couplings are designed as bellows or gauntlets. However, they have the disadvantage that they lie in the flow of the conveyed material and are deformed by the pressure of the same and cannot be easily exchanged, as is the case with a known one Execution is the case. Another known design is a metal-rubber joint provided, which is designed #pressure-proof, but the toothed part of the Coupling does not seal, which means that conveyed goods cannot enter the inner spherical Part can be done. In the case of seals of this type, it must also be replaced the same a large part of the coupling removed and again by gluing or vulcanizing be connected to each other.

Erfindungsgemäß werden diese Nachteile dadurch beseitigt, daß die mit einem äußeren Ring verbundene, besonders widerstandsfähige ringförmige Ab- dichtung mit einem inneren Ring zur paßgerechten Anlage an dem einen Wellenende verbunden ist und die druckdichte Verbindung der Abdichtung mit den beiden Ringen in bekannter Weise durch Kleben oder Vulkanisieren erfolgt. Die Dichtung besteht demnach aus einem Stück und kann daher leicht ausgewechselt werden, wozu mit geringem Kostenaufwand mehrere Ersatzstücke auf Lager gehalten werden können. Gleichzeitig wird der Innenteil der Kupplung gegen das Fördergut vollkommen dicht abgeschlossen bzw. der Austritt von Schmiermitteln verhindert, was bei der Förderung von Lebens- oder Genußmitteln besonders wichtig ist.According to the invention these drawbacks are eliminated by the connected to an outer ring, highly resilient annular seal at the one shaft end is connected to an inner ring for paßgerechten system and the pressure-tight connection of the seal with the two rings in known manner by gluing or Vulcanizing takes place. The seal therefore consists of one piece and can therefore be easily replaced, for which purpose several replacement pieces can be kept in stock at low cost. At the same time, the inner part of the coupling is completely sealed against the conveyed goods or the escape of lubricants is prevented, which is particularly important when conveying foodstuffs or luxury foods.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel im Längsschnitt dargestellt.In the drawing, the subject matter of the invention is in one embodiment shown in longitudinal section.

Die Zahnkupplung 1 ist in einer sie umgebenden Hülse 2 eingebaut und mit dem innenverzahnten Teil 3 auf der Antriebswelle 4 aufgebracht. Die aus einem Dichtungsring 5 und den Metallringen 6 und 7 bestehende Abdichtung liegt mit ihrem äußeren Ring 6 teils am Gehäuse 2 und teils an dem kalottenförmigen Teil 8 der Zahnkupplung an. Der innere Ring 7 ist auf der Antriebswelle 4 so aufgebracht, daß er an deren Bund 9 anliegt und an der entge ' gengesetzten Seite von dem innenverzahnten Teil 3 angepreßt wird. Die ringförmige Abdichtung kann besonders stark ausgebildet werden.The toothed coupling 1 is installed in a sleeve 2 surrounding it and attached to the drive shaft 4 with the internally toothed part 3. The seal consisting of a sealing ring 5 and the metal rings 6 and 7 rests with its outer ring 6 partly on the housing 2 and partly on the dome-shaped part 8 of the tooth coupling. The inner ring 7 is applied to the drive shaft 4 so that it rests on the collar 9 and is pressed against the entge 'gengesetzten side of the internally toothed part. 3 The annular seal can be made particularly strong.
