Description
Federring Als Unterlegplatte für Schrauben und Muttern sind gestanzte Ringe bekannt. Spring washer As a base plate for screws and nuts are punched Rings known.
Um ein Lösen der Schraubenmuttern zu verhindern ist es auch bekannt, eine oder beide Auflageflächen der Unterlegplatte mit einer Verzahnung oder Riffelung zu versehen. Die Riffelung oder Verzahnung dient dazu, ein Lösen der festgezogenen Schraube oder Mutter zu verhindern. Dem gleichen Zweck dient ein bekannter Federring, der aus einem radial geschlitzten Ring besteht, dessen durch den Schlitz gebildete Enden nach entgegengesetzten Seiten aufgebogen sind. Diese bekannten Unterlegscheiben und Federringe sind Stanzteile, die aus Blechstreifen unter erheblichem Materialverlust ausgestanzt werden müssen. To prevent the nuts from loosening, it is also known to one or both bearing surfaces of the base plate with a toothing or corrugation to provide. The corrugation or toothing is used to loosen the tightened To prevent screw or nut. A well-known spring washer serves the same purpose, which consists of a radially slotted ring, the one formed by the slot Ends are bent up to opposite sides. These well-known washers and spring washers are stamped parts that are made from sheet metal strips with considerable material loss must be punched out.
Ziel der vorliegenden Erfindung ist nun, einen Federring zu schaffen, der einfacher und billiger herzustellen ist als die bekannten gestanzten. The aim of the present invention is now to create a spring ring, which is easier and cheaper to manufacture than the known punched ones.
Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß der Federring aus verdrilltem und zu einem Ring gebogenen Metallstreifen besteht.To solve this problem it is proposed according to the invention that the spring ring consists of twisted metal strips bent into a ring.
Der erfindungsgemäße Federring kann in sehr einfacher Weise, ausgehend von einem ebenen Metallstreifen (Fig. 1), verdrillt werden (Fig. 2) und dann zu einem Ring beliebigen Durchmessers gebogen werden (Fig. 3), wobei noch die Enden des Rings, z. B. durch Schweißen oder Löten miteinander verbunden werden können. Beim Anziehen der Schraube oder Mutter wird der erfindungsgemäße Federring zusammengedrückt und verformt sich elastisch. Dem Lösen derSchraube oder Mutter setzen die durch die Verdrillung entstandenen schuppenartig geformten, am Schraubenkopf oder an der Schraubenmutter und an der Gegenfläche anliegenden Kanten des erfindungsgemäßen Federrings Widerstand entgegen, wohingegen die Schraube oder Mutter beim Festziehen über die schuppenartigen Kantenvorsprünge des erfindungsgemäßen F ederrings hinweg gleitet.The spring ring according to the invention can be started in a very simple manner from a flat metal strip (Fig. 1), twisted (Fig. 2) and then to a ring of any diameter can be bent (Fig. 3), still the ends of the ring, e.g. B. can be connected to one another by welding or soldering. When the screw or nut is tightened, the spring washer according to the invention is compressed and deforms elastically. The loosening of the screw or nut prevails the twisting created scale-like, on the screw head or on the Screw nut and the edges of the invention that lie against the mating surface Spring ring counteracts resistance, whereas the screw or nut when tightening over the scale-like edge projections of the spring ring according to the invention slides.
Der erfindungsgemäße Federring -ist nicht nur leicht herzustellen sondern verursacht bei seiner Herstellung praktisch keinerlei Materialverlust.The spring ring according to the invention is not only easy to manufacture but causes practically no loss of material in its manufacture.
Außerdem erfordert er weniger Materialaufwand und ist damit leichter und billiger als herkömmliche Federringe. Schließlich ist seine Wirksamkeit hinsichtlich unbeabsichtigten Lösens von Schrauben und Schraubenmuttern besser als die bekannter Federringe, was auf der Vielzahl der gebildeten Kantenvorsprünge beruht.In addition, it requires less material and is therefore lighter and cheaper than conventional spring washers. Ultimately, its effectiveness is as to unintentional loosening of screws and nuts better than known Spring washers, which is based on the large number of edge projections formed.
