Description

Das Patent 871236 betrifft ein Dichtungselement mit Stützkörper und elastischen Dichtlippen zum Abdichten von gegeneinander bewegten Maschinenteilen od. dgl., bei dem die Dichtlippen fest mit dem die Einspannkräfte aufnehmenden Stützkörper verbunden und auf flanschartigen, zur Richtung des Arbeitsdrucks senkrecht angeordneten Vorsprüngen des Stützkörpers angebracht sind.The patent 871236 relates to a sealing element with support body and elastic sealing lips for sealing machine parts that move against each other or the like, in which the sealing lips are firmly attached to the support body which absorbs the clamping forces connected and arranged on flange-like, perpendicular to the direction of the working pressure Projections of the support body are attached.

Ein solches Dichtungselement wird gemäß der Erfindung dadurch weiter ausgebildet, daß in den Dichtlippen Versteifungsteile angeordnet sind, die eine die Dichtwirkung erhöhende, in Richtung auf den Lippenrand zunehmende Federung der Lippen bewirken. Zweck der Versteifungsteile ist es, den Dichtlippen eine höhere Festigkeit gegen Verbiegen und Abreißen zu geben, wenn z. B. aus besonderen Gründen, wie Dichtheit, Abreibfestigkeit, chemische Beständigkeit, eine weiche Werkstoffqualität benötigt wird, die nicht eine genügende mechanische Festigkeit besitzt. Durch die Einlagerung der Versteifungsteile in die Dichtlippen werden äußerlich hervorstehende Teile vermieden, die bei einer äußeren Federung, z. B. Schlauchfeder, Spannring, vorhanden sind.Such a sealing element is further developed according to the invention formed that stiffening parts are arranged in the sealing lips, the one the sealing effect increasing, increasing in the direction of the lip edge of the spring Effect lips. The purpose of the stiffening parts is to give the sealing lips a higher one To give strength against bending and tearing, if z. B. for special reasons, such as tightness, abrasion resistance, chemical resistance, a soft material quality is needed that does not have sufficient mechanical strength. Through the Storage of the stiffening parts in the sealing lips are externally protruding Avoided parts that are in an external suspension, z. B. hose spring, clamping ring, available.

Die Anordnung nach der Erfindung kann so getroffen sein, daß die Versteifungsteile in den Dichtlippen z. B. kammartig zusammenhängen und gegebenenfalls mit dem Stützkörper verbuniden sind.The arrangement according to the invention can be made so that the stiffening parts in the sealing lips z. B. related in a comb-like manner and optionally with the support body are connected.

In der Zeichnung ist die Erfindung beispielsweise veranschaulicht.The invention is illustrated by way of example in the drawing.

Abb. i zeigt ein Dichtungselement mit den Dichtlippen i, deren Dichtwirkung an den Kanten 2 erhöht werden soll. Hierzu dienen die Versteifungsteile 3, die in den Dichtlippen vorgesehen sind.Fig. I shows a sealing element with the sealing lips i, their sealing effect should be increased at the edges 2. The stiffening parts 3, which are shown in FIG the sealing lips are provided.

Gemäß Abb. 2, welche die Versteifungsteile der äußeren Lippe darstellt, wird ein-kammartiger Ring benutzt, der aus dem ringförmigen Teil 5 und den Zähnen 6 besteht. Der Ring 5 kann mit dem Stützkörper q. verbunden sein. Es ist ohne weiteres ersichtlich, daß bei einer solchen Ausbildung der Versteifungsteile die Federung der Lippen in Richtung auf den Lippenrand zunimmt.According to Fig. 2, which shows the stiffening parts of the outer lip, a comb-like ring is used, which consists of the annular part 5 and the teeth 6 consists. The ring 5 can with the support body q. be connected. It is straightforward it can be seen that with such a design of the stiffening parts, the suspension of the lips increases in the direction of the lip edge.
