Abstract
Description
Die Erfindung bezieht sich auf eine Gewindeschraube mit einem Werkzeugangriff und einer koaxial zur Schraubenachse einstückig angeformten Federscheibe, die mit ihrem ringförmigen Rand eine Ringanlage zu einem die Gewindeschraube aufnehmenden Werkstück bildet. The invention relates to a threaded screw with a tool engagement and a coaxial with the screw axis integrally formed spring washer, which forms with its annular edge a ring system to a threaded screw receiving workpiece.
Eine derartige Schraube ist in der
Der Erfindung liegt die Aufgabe zugrunde, die Wirkung der Federscheibe wesentlich zu intensivieren und damit die Dauerhaftigkeit der durch die Schraube hergestellten Verbindung in besonders sicherer Weise zu gewährleisten. Erfindungsgemäß geschieht dies dadurch, dass zwischen der Schraubenachse und dem Rand die Federscheibe diese mit mindestens einer Knickstelle versehen ist, deren Schenkel derart verlaufen, dass der eine Schenkel zur Schraubenachse und der andere Schenkel auf das Werkstück zu gerichtet ist. The invention has for its object to significantly intensify the action of the spring washer and thus to ensure the durability of the compound produced by the screw in a particularly secure manner. According to the invention, this is done in that between the screw axis and the edge of the spring washer is provided with at least one kink, the legs of which run so that one leg to the screw axis and the other leg is directed to the workpiece.
Durch die in die Federscheibe eingebrachte Knickstelle wird die Federkennlinie der Federscheibe im Sinne wesentlich erhöhter Elastizität in wünschenswerter Weise verändert. Durch den Knick, insbesondere seinen Knickwinkel, lässt sich außerdem in besonderer Weise der Federdruck einstellen und damit die betreffenden Verbindung jeweils einem bestimmten Druck aussetzen, der möglicherweise nicht überschritten werden darf, dabei aber dann auch besonders dauerhaft wirksam sein soll. By introduced into the spring washer kink, the spring characteristic of the spring washer in the sense of significantly increased elasticity is changed in a desirable manner. Due to the kink, in particular its bending angle, can also be set in a special way, the spring pressure and thus expose each compound to a certain pressure, which may not be exceeded, but then it should be particularly durable.
Eine besondere Gestaltungsmöglichkeit der Federkennlinie der Federscheibe ergibt sich dadurch, dass der Schenkel der Federscheibe zwischen Gewindeschraube und Knickstelle stärker ausgebildet ist als der Schenkel, der nach außen hin der betreffenden Knickstelle folgt. Durch diese Gestaltung des Bereiches der Federscheibe zwischen Gewindeschraube und Knickstelle lässt sich wahlweise unter Ausnutzung einer bestimmten Stärke der Federscheibe im Bereich der Knickstelle deren Federkennlinie in erheblichen Umfang beeinflussen. A special design possibility of the spring characteristic of the spring washer results from the fact that the leg of the spring washer between the threaded screw and kink is formed stronger than the leg, which follows outwardly of the respective kink. This configuration of the area of the spring washer between the threaded screw and the kink allows the spring characteristic to be influenced to a considerable extent, optionally by utilizing a certain thickness of the spring washer in the region of the kink.
Eine weitere ergänzende Möglichkeit des Einflusses auf die Federkennlinie erhält man dadurch, dass die Federscheibe mit zwei Knickstellen versehen ist. Bei zwei Knickstellen ergibt sich zusätzlich die Möglichkeit der Beeinflussung der Federkennlinie dadurch, dass die Bereiche außerhalb der Knickstellen unterschiedlich dick sind. Another additional possibility of influencing the spring characteristic is obtained by the fact that the spring washer is provided with two kinks. In the case of two kinks, there is additionally the possibility of influencing the spring characteristic in that the regions outside the kinks have different thicknesses.
Je nach Stärke der Bereiche zwischen den Knickstellen und den Winkeln der Knickstellen lässt sich weiterhin die Federkennlinie in wünschenswerter Weise beeinflussen. Damit liegt eine Gewindeschraube mit geformter Federscheibe vor, die sich in einem weiten Umfang an die jeweils erforderlichen Gegebenheiten anpassen lässt. Depending on the strength of the areas between the kinks and the angles of the kinks can continue to influence the spring characteristic in a desirable manner. This is a threaded screw with a shaped spring washer, which can be adapted to a large extent to the particular circumstances required.

Es können die einzelnen Darstellungen gemäß den vorstehend beschriebenen Figuren auch in anderer Weise miteinander verknüpft werden, um jeweils eine besondere Federkennlinie für die Federkopfschraube zu erzielen. The individual representations according to the figures described above can also be linked to each other in a different way in order in each case to achieve a special spring characteristic for the spring-head screw.
