Abstract

By means of this elastic slip ring protection, the penetration of dirt between the O-ring which operates as spring, the sealing ring and the outer element is prevented and thus the elastic function of the O-ring is maintained. The sealing housing simplifies the machining of steel components.

Description

Bei den bekannten Gleitringdichtungen, die insbesondere bei Laufrollen, Leiträdern und Antriebswellen Verwendung finden, kommt es immer wieder vor, daß durch eindringenden Schmutz in der Öffnung 1 zwischen Dichtungsring 2, O-Ring 3 und Außenkörper 4 die erforderliche Federarbeit für die Vorspannung der Dichtung verloren geht bzw. wesentlich behindert wird mit dem Ergebnis, daß die Dichtungshälften nicht mehr fest gegeneinander gedrückt werden und somit Öl austritt.In the known mechanical seals, which are used in particular in the case of rollers, idlers and drive shafts, it happens again and again that the spring work required for prestressing the seal is lost due to dirt entering the opening 1 between the sealing ring 2 , the O-ring 3 and the outer body 4 goes or is significantly hampered with the result that the seal halves are no longer pressed firmly against each other and thus oil escapes.

Diese Erfindung hat sich zur Aufgabe gemacht, dieses Problem abzustellen.The object of this invention is to solve this problem to turn off.

Die Dichtungslippe 5 des elastischen Dichtungsschutzes wird bei der Montage der Dichtung fest gegen den Außenkörper 4 gedrückt, wodurch das Eindringen von Schmutz verhindert wird.The sealing lip 5 of the elastic seal protection is pressed firmly against the outer body 4 during assembly of the seal, thereby preventing the ingress of dirt.
