Description

DEUTSCHESGERMAN

Die Erfindung betrifft Gummi-Metall-Federn zur Befestigung von Maschinen od. dgl. beziehungsweise für deren Teile.The invention relates to rubber-metal springs for fastening machines od. The like. Or for their parts.

Die Gummi-Metall-Feder ist mit einer Hülle aus Gummi oder Kunststoff umgeben, welche gegebenenfalls eine Verstärkungseinlage aus Gewebe hat. Während man bisher derartige Umhüllungen nur zum Schutz der Federn vorgesehen hat, ist gemäß der Erfindung die Hülle derart ausgebildet, daß sie der statischen Belastung der Feder entgegenwirkende Stöße unter Zugbelastung aufnimmt und ein Auseinandergehen der Metallplatten der Gummi-Metall-Feder begrenzt.The rubber-metal spring is surrounded by a cover made of rubber or plastic, which if necessary has a reinforcement insert made of fabric. While so far such covers only for Has provided protection of the springs, according to the invention, the shell is designed such that it the static load of the spring absorbs impacts counteracting tensile load and a divergence bounded by the metal plates of the rubber-metal spring.

Bei der Anwendung von Gummi-Metall-Federn, die auf Druck beansprucht sind oder auch als Dämpfer wirken, können der statischen Last entgegengerichtete Stoßbeanspruchungen auftreten, die ein Auseinandergehen der die Kraftleitungsflächen darstellenden Metallplatten bewirken. Solche zusätzlichen Beanspruchungen können sogar Zugkräfte im Gummi hervorrufen. In Gummi enthaltenden Konstruktionsteilen sind aber Zugbeanspruchungen, wenn irgendmöglich, zu vermeiden, da eine Zugbeanspruchung für Gummi die ungünstigste Belastungsform ist; es können dann leicht Beschädigungen auftreten, weil unter Zug die Kerbzähigkeit des Gummis außerordentlich gering ist.When using rubber-metal springs that are subjected to pressure or as dampers act, the static load opposite impact loads can occur, which a Divergence of the surfaces representing the force transmission Effect metal plates. Such additional stresses can even cause tensile forces in the rubber cause. In construction parts containing rubber, however, tensile loads are, if at all possible, to be avoided, as tensile stress is the most unfavorable form of stress for rubber; it Damage can then easily occur because, under tension, the notch toughness of the rubber is extraordinary is low.

Die gemäß der Erfindung um die Gummi-Metall-Feder vorgesehene Hülle kann aus einem vorgeformten Schlauch bestehen, in welchen die Gummi-Metall-Feder von einem Ende aus eingeführt ist.The provided according to the invention around the rubber-metal spring can consist of a preformed Hose consist in which the rubber-metal spring is inserted from one end.

Die Metallplatten der Gummifeder können die Hülle überragen, während das Gummikissen innerhaln der Hülle liegt. Man kann auch die Außenflächen der Metallplatten kröpfen und die Hülle in dieser Kröpfung anordnen. Die Enden der Hülle können an den Metallplatten befestigt sein.The metal plates of the rubber spring can protrude over the cover, while the rubber cushion inside the shell lies. You can also crank the outer surfaces of the metal plates and the casing in this Arrange crank. The ends of the sheath can be attached to the metal plates.

Die Hülle kann auch aus zwei schlauchförmigen Abschnitten bestehen, deren benachbarte Enden aneinanderstoßen und miteinander verbunden sind, z. B. mittels eines die benachbarten Enden abdeckenden schlauchförmigen Bandes.The sheath can also consist of two tubular sections, the adjacent ends of which abut one another and are interconnected, e.g. B. by means of a covering the adjacent ends tubular band.

Die Hülle kann aus Naturgummi, Kunstgummi oder Mischungen davon bestehen und gegebenenfalls mittels einer Gewebeeinlage verstärkt sein. An Stelle von Gummi können auch Kunststoffe verwendet werden, z. B. Polyamide.The sheath can consist of natural rubber, synthetic rubber or mixtures thereof and optionally be reinforced by means of a fabric insert. Instead of rubber, plastics can also be used, z. B. polyamides.

welche Zugkräfte vom Gummikissen fernhält und außerdem in an sich bekannter Weise dessen Seitenflächen schützt. Die aus Metall bestehenden Platten 8 sind nach außen abgebogen, wodurch Kröpfungen 9 entstehen. Bei der Befestigung eines Maschinenteiles (strichpunktiert angedeutet) ist also die Hülle 6 nicht zwischen diesen Teilen und den Platten 8 eingespannt. Im Gummikissen kann eine Zwischenplatte angeordnet sein.which keeps tensile forces away from the rubber cushion and also its side surfaces in a manner known per se protects. The plates 8 made of metal are bent outwards, creating offsets 9 develop. When a machine part is fastened (indicated by dash-dotted lines), the casing 6 is therefore not clamped between these parts and the plates 8. An intermediate plate can be placed in the rubber cushion be arranged.
