Abstract
Federorgan mit dämpfenden Eigenschaften mit einem Gehäuse, dass eine balgförmige, elastomere Ummantelung aufweist, deren offenen Enden durch Befestigungsorgane abgedichtet sind, wobei das Gehäuse über die Befestigungsorgane mit abzufedernden Maschinenteile verbunden ist, dadurch gekennzeichnet, dass das Gehäuse (2) mit einer Füllung (7) aus zelligem Polyurethan auf Isocyanatbasis gefüllt ist, wobei die Dichte der Füllung (7) im Gehäuse (2) ca. 100 bis 300 Gramm pro Liter beträgt.spring member with steaming Properties with a housing, that a bell-shaped, having elastomeric sheath whose open ends by fastening members are sealed, the housing over the Fastening elements is connected with parts of the machine to be spring-loaded, characterized in that the housing (2) with a filling (7) is filled with isocyanate - based cellular polyurethane, the density of the Filling (7) in the case (2) is about 100 to 300 grams per liter.
Description
Die Erfindung betrifft ein Federorgan mit dämpfenden Eigenschaften mit einem Gehäuse, das eine balgförmige, elastomere Ummantelung aufweist, deren offenen Enden durch Befestigungsorgane abgedichtet sind, wobei das Gehäuse über die Befestigungsorgane mit abzufedernden Maschinenteilen verbindbar ist.The The invention relates to a spring member having damping properties with a housing, the one bellow-shaped, having elastomeric sheath whose open ends by fastening members are sealed, the housing over the Fasteners connectable with parts of the machine to be mitigated is.
Derartige
Federorgane, auch Federbalge genannt, sind hinreichend bekannt.
So beschreibt die deutsche Offenlegungsschrift
Der Erfindung liegt daher die Aufgabe zugrunde, ein Federorgan der oben genannten Art zu schaffen, der die Beibehaltung der Feder- und Dämpfungseigenschaften über die gesamte Lebensdauer gewährleistet.Of the Invention is therefore based on the object, a spring member of the above mentioned type, the maintenance of the spring and damping properties on the guaranteed lifetime.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Gehäuse mit einer Füllung aus zelligem Polyurethan auf Isocyanatbasis gefüllt ist, wobei die Dichte der Füllung im Gehäuse ca. 100 bis 300 Gramm pro Liter beträgt.The The object is achieved in that the housing with a filling is filled with isocyanate - based cellular polyurethane, the density of the filling in the case about 100 to 300 grams per liter.
Durch eine derartige Ausführung besitzt das Federorgan progressive Federeigenschaften mit optimalen Selbstdämpfungs-Eigenschaften. Darüber hinaus führen kleinere Undichtigkeiten an den Befestigungsorganen oder in der Ummantelung nicht zu einem Funktionsverlust des Federorgans.By Such an embodiment The spring organ has progressive spring characteristics with optimal Self-damping properties. About that lead out minor leaks in the attachment organs or in the Sheath not to a loss of function of the spring element.
Besonders gute Ergebnisse wurden erzielt mit einer Füllung, die als Granulat ausgebildet ist, wobei die Formteile des Granulats zwischen 1 und 5 mm betragen. Als hervorragend geeigneter Werkstoff für die Füllung hat sich darüber hinaus Vulkollan® erwiesen. Der Werkstoff Vulkollan® zeichnet sich dabei insbesondere durch eine Anzahl herausragender Eigenschaften aus, wie zum Beispiel einem ausgezeichneten mechanischen Verschleißwiderstand, eine hohe Stoßelastizität auch bei einer harten Einstellung und einem hohen Weiterreißwiderstand. Auf diese Weise ist die Füllung über die gesamte Lebensdauer des Federorgans als ermüdungsfrei anzusehen.Particularly good results were achieved with a filling which is formed as granules, wherein the moldings of the granules are between 1 and 5 mm. In addition, Vulkollan ® has proven to be an excellent material for filling. The material Vulkollan ® is characterized in particular by a number of outstanding properties, such as an excellent mechanical wear resistance, high impact resilience even with a hard setting and a high tear propagation resistance. In this way, the filling over the entire life of the spring member is considered to be fatigue-free.
