Aus der
Eine Zusammensetzung für einen Elastomerkörper einer hochelastischen Wellenkupplung zur Drehmomentübertragung ist bekannt. Derartige Zusammensetzungen betreffen entweder Naturkautschukmischungen oder Silikon.A composition for an elastomeric body of a high-elastic shaft coupling for transmitting torque is known. Such compositions relate to either natural rubber blends or silicone.
Aufgabe der Erfindung ist es, eine hochelastische Wellenkupplung sowie eine Verwendung eines ringförmigen Elastomerkörpers der eingangs genannten Art zu schaffen, die einen Einsatz zur Drehmomentübertragung von Antriebskomponenten in einem Dauereinsatztemperaturbereich von 110°C bis 130°C ermöglichen.The object of the invention is to provide a highly elastic shaft coupling and a use of an annular elastomer body of the type mentioned, which allow use for torque transmission of drive components in a continuous use temperature range of 110 ° C to 130 ° C.
Diese Aufgabe wird durch den Patentanspruch 1 sowie durch den Patentanspruch 7 gelöst.This object is achieved by the patent claim 1 and by the patent claim 7.
EPDM (Ethylen-Propylen-Dien-Monomer) weist eine gute Hitzebeständigkeit sowie eine Beständigkeit gegenüber Wasser, Laugen, verdünnten Säuren und Alkoholen auf. Die gute Hitzebeständigkeit ermöglicht den Einsatz der Zusammensetzung für einen Elastomerkörper einer hochelastischen Wellenkupplung zur Drehmomentübertragung bei Antriebskomponenten, die in einem Dauereinsatztemperaturbereich zwischen 110°C und 130°C betreibbar ist. Der Rußanteil gewährleistet eine ausreichende Härte und Reißfestigkeit, um die Zusammensetzung bei einem entsprechenden Elastomerkörper für eine hochelastische Wellenkupplung zur Drehmomentübertragung einzusetzen. Die Erfindung ist vorteilhaft im Maschinen- oder Anlagenbau oder im Fahrzeug- und Schiffsbau, jeweils für entsprechende Antriebskomponenten einsetzbar.EPDM (Ethylene Propylene Diene Monomer) has good heat resistance and resistance to water, alkalis, dilute acids and alcohols. The good heat resistance allows the use of the elastomeric body composition of a highly flexible shaft coupling for torque transmission in drive components which is operable in a continuous service temperature range between 110 ° C and 130 ° C. The carbon black content provides sufficient hardness and tear strength to utilize the composition in a corresponding elastomeric body for a high-elastic torque-transmitting shaft coupling. The invention is advantageously used in mechanical or plant engineering or in vehicle and shipbuilding, in each case for corresponding drive components.
Besonders vorteilhaft weist EPDM einen Anteil zwischen 55 Gew.-% und 65 Gew.-% auf. Vorzugsweise ist Ruß mit einem Anteil zwischen 30 Gew.-% und 38 Gew.-% vorgesehen. Diese Zusammensetzung ist besonders vorteilhaft für die Einsatztemperatur hochelastischer Wellenkupplungen oberhalb von 90°C bei gleichzeitig hohen dynamischen Festigkeiten und Weiterreißfestigkeiten.Particularly advantageously, EPDM has a proportion of between 55% by weight and 65% by weight. Preferably, carbon black is provided at a level of between 30% and 38% by weight. This composition is particularly advantageous for the operating temperature of highly flexible shaft couplings above 90 ° C with high dynamic strength and tear propagation.
In weiterer Ausgestaltung der Erfindung umfasst die Zusammensetzung als weitere Komponenten Metalloxid und Stearinsäure. Dadurch wird eine weitere Verbesserung der Hitzebeständigkeit, eine Verbesserung des elastischen Verhaltens sowie eine Erhöhung der Geschwindigkeit der Vernetzung bei der Verarbeitung der Zusammensetzung erzielt. Besonders vorteilhaft ist als Metalloxid Zinkoxid vorgesehen, und Zinkoxid ist mit Stearinsäure mit einem Anteil zwischen 1,35 Gew.-% und 4 Gew.-% enthalten. Die Anteilsangabe beziehen sich auf eine Gesamteinwaage der Zusammensetzung.In a further embodiment of the invention, the composition comprises, as further components, metal oxide and stearic acid. This achieves a further improvement of the heat resistance, an improvement of the elastic behavior as well as an increase of the speed of crosslinking in the processing of the composition. Zinc oxide is particularly advantageously provided as the metal oxide, and zinc oxide is contained with stearic acid in an amount of between 1.35% by weight and 4% by weight. The shares are based on a total weight of the composition.
In weiterer Ausgestaltung der Erfindung ist als weitere Komponente Schwefel mit einem Anteil von 0,1 Gew.-% bis 1 Gew.-% vorgesehen, auf eine Gesamteinwaage der Zusammensetzung bezogen. Durch ein derartiges schwefelvernetztes System werden die elastischen Eigenschaften der Zusammensetzung weiter verbessert.In a further embodiment of the invention is provided as a further component sulfur in a proportion of 0.1 wt .-% to 1 wt .-%, based on a total weight of the composition. Such a sulfur crosslinked system further improves the elastic properties of the composition.
Die erfindungsgemäße, hochelastische Wellenkupplung eignet sich in besonders vorteilhafter Weise für drehschubbelastete Wellenkupplungen, bei denen die Elastomerkörper im Kupplungsbetrieb Materialdehnungen von mehr als 20% ausgesetzt sind.The inventive, highly elastic shaft coupling is suitable in a particularly advantageous manner for drehschubbelastete shaft couplings in which the elastomeric body in the coupling operation material expansions of more than 20% are exposed.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Ansprüchen sowie aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele der Erfindung, die anhand der Zeichnungen dargestellt sind.Further advantages and features of the invention will become apparent from the claims and from the following description of preferred embodiments of the invention, which are illustrated by the drawings.
