Korrosionsgeschützte, endlos geschlossene WurmfederCorrosion-protected, endlessly closed worm spring

Gegenstand der Neuerung ist eine korrosionsgeschützte, endlos geschlossene Wurmfeder. Solche Federn sind zum Beispiel zum Anpressen der Dichtlippe an die Welle bei Radialdichtringen bekannt. Zum Schutz gegen Korrosion und Verschmutzung hat man solche Federn bereits mit einem einzeln hergestellten Schlauch überzogen. Abgesehen von dem mühseligen Arbeitsgang des Schlauchüberziehens mußte dabei der Schlauch an der Stoßstelle sich überlappen, so daß eine örtliche Verdickung eintritt. Außerdem ist diese Überlappung gegen Feuchtigkeit, Wasser und sonstige Verunreinigungen meistens nicht dicht genug, um einen absoluten Schutz darzustellen»The object of the innovation is a corrosion-protected, endlessly closed worm spring. Such springs are for example Pressing the sealing lip against the shaft is known for radial sealing rings. To protect against corrosion and pollution one has such springs already covered with a individually manufactured hose. Apart from the laborious process of the When pulling the hose over, the hose had to overlap at the joint, so that a local thickening occurs. aside from that is this overlap against moisture, water and others Impurities mostly not dense enough to be an absolute To represent protection »

Diese Nachteile sind bei der Neuerung dadurch ausgeschaltet, daß die geschlossene Feder durch ein besonderes Verfahren mit einer endlosen,: allseits geschlossenen, dichten Ummantelung aus gummielastischem Material umgeben wird. Die Schutzschicht kann entweder die Feder lose umgeben oder aber festhaftend mit dieser verbunden sein. Dadurch ist ein absoluter Schutz gegen äußere Verunreinigungen, die zur Korrosion der Feder und zum Blockieren der einzelnen Federwindungen führen, gegeben, ohne daß die Dehnbarkeit der Feder beeinträchtigt wird.These disadvantages are eliminated with the innovation, that the closed spring is made by a special process with an endless, dense casing that is closed on all sides is surrounded by rubber-elastic material. The protective layer can either loosely surround the spring or it can be firmly adhered be connected to this. This is an absolute protection against external contamination that can corrode the spring and lead to the blocking of the individual spring coils, without affecting the elasticity of the spring.

In der Zeichnung ist die Feder entsprechend der Neuerung dargestellt, bestehend aus der eigentlichen Wurmfeder (1) mit der bekannten, durch Eindrehen hergestellten endlosen Verbindung (2) und der neuerungsgemäßen Ummantelung aus gummielastischem Werkstoff (3).In the drawing, the spring is shown according to the innovation, consisting of the actual worm spring (1) with the known endless connection produced by screwing (2) and the rubber-elastic sheathing according to the innovation Material (3).
