Description

Dichtungsringe und Dichtungskörper aller Art werden seit Jahren in steigendem Maße aus Sintereisen hergestellt. Hierbei hat man ihre Gestalt und Abmessungen ganz schematisch den früher benutzten Ringen aus Kupfer,. Messing, Blei, Asbest usw. angeglichen. Dadurch war es bisher nicht möglich, bei Sintereisenringen die gleichen Gebrauchseigenschaften zu erzielen, wie sie beispielsweise ein Kupfer-Asbest-Dichtungsring besitzt. Während bei diesem die Umhüllung-aus Kupferblech der Träger der erforderlichen Festigkeit ist, gewährleistet die eingeschlossene Asbestmasse eine ausreichende Verformbarkeit des Werkstückes. Bei den heute üblichen Dichtungsringen aus Sintereisen von rechteckigem Querschnitt kann, man aber die eine der erforderlichen Eigenschaften immer nur auf Kosten der anderen erzielen. Wird der Ring unter hohem Druck gepreßt, so besitzt er zwar eine ausreichende Festigkeit, aber eine zu geringe Verformbarkeit; wird er bei niedrigem Druck gepreßt, dann ist er zwar gut verformbar, aber zu wenig fest.Sealing rings and sealing bodies of all kinds have been in use for years increasingly made of sintered iron. Here you have their shape and dimensions very schematically the copper rings used earlier. Brass, lead, asbestos etc. adjusted. As a result, it was previously not possible to use the to achieve the same performance properties as, for example, a copper-asbestos sealing ring owns. While with this the sheathing-made of copper sheet the carrier of the required Strength is, the enclosed asbestos mass ensures sufficient Deformability of the workpiece. With the now common sealing rings made of sintered iron of rectangular cross-section can, but one of the required properties always achieve only at the expense of others. If the ring is pressed under high pressure, it has sufficient strength, but too little deformability; if it is pressed at low pressure, it can be deformed well, but not enough fixed.

Die vorliegende Erfindung hat einen Dichtungsring aus Sintereisen zum Gegenstand, der an verschiedenen Querschnittsstellen eine unterschiedliche Dichte und Festigkeit besitzt. Bei der Herstellung dieser Ringe macht man von dier Tatsache Gebrauch, daß ein PreBkörper von unterschiedlichem Querschnitt, der nach dem üblichen einfachen Preßverfahren hergestellt worden ist, über seinen Querschnitt auch eine unterschiedliche Dichte und Festigkeit besitzt. Demgemäß besitzt der neue Dichtungsring einen oder mehrere ringförmige Wülste oder andere Verdickungen. In der Abbildung sind zwei Ausführungsbeispiele dargestellt. Bei der Herstellung dieser Ringe auf einer einfach wirkenden Presse wird das Pulver an den verdickten Stellen weniger fest gepreßt, so daß diese weich und verformbar bleiben. An den übrigen Stellen, insbesondere an .den Rändern, erhält man automatisch eine stärkere Pressung und eine entsprechend höhere Festigkeit.The present invention has a sintered iron sealing ring the subject, which has a different density at different cross-sectional locations and has strength. When making these rings one makes of fact Use that a pressed body of different cross-section, according to the usual simple pressing process has been produced, over its cross-section also a has different density and strength. Accordingly, the new sealing ring has one or more annular bulges or other thickenings. In the picture two exemplary embodiments are shown. When making these rings on a single-acting press, the powder will be less in the thickened areas pressed firmly so that they remain soft and malleable. In the other places, especially at the edges, you automatically get a stronger pressure and a correspondingly higher strength.

Praktische Versuche mit dem neuen Dichtungsring haben seine eindeutige Überlegenheit gegenüber den bisher verwendeten Ringen ergeben. Der Erfindungsgedanke kann mit dem gleichen Erfolg natürlich auch bei der Herstellung anderer DichtungskÖrper verwertet werden.Practical tests with the new sealing ring have been unequivocal Superiority over the previously used rings. The idea of the invention can of course also produce other seals with the same success be recycled.
