SchraubenfederCoil spring

Die Erfindung bezieht sich auf eine hochbeanspruchte Schraubenfeder (Druckfeder).The invention relates to a highly stressed helical spring (Compression spring).

Hochbeanspruchte, insbesondere hochbeschleunigte Schraubenfedern neigen zu Brüchen im Federdraht. Bei großen Beschleunigungen kommen die Federwindungen zur Anlage (Blockbildung), und es entstehen Eigenschwingungen des Federdrahtes, die zue; Bruch führen können. Außerdem wird dabei meist die Innenfläche der Zylinderführung der Feder beschädigt.Highly stressed, especially highly accelerated coil springs tend to break in the spring wire. At high accelerations, the spring coils come into contact (block formation), and natural oscillations of the spring wire arise, the zue; Can lead to breakage. In addition, the inner surface of the cylinder guide of the spring is usually damaged.

Aufgabe der Erfindung ist es, die Feder so auszubilden, αaß sie auch großen Beschleunigungen standhalten kann. Diese Aufgabe wird erfindungsgemäß durch das im Kennzeichen des Hauptanspruchs enthaltene Merkmal gelöst.The object of the invention is to design the spring so that it αass can also withstand large accelerations. This object is achieved according to the invention by the characterizing part of the main claim contained feature solved.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The drawing shows an embodiment of the invention.

Der Federdraht 1 der Schraubenfeder ist zum Teil mit einer Kunststoffummantelung 2 versehen.The spring wire 1 of the helical spring is partially provided with a plastic sheath 2.

Als Kunststoff kann z.B. Polyurethan (PUR) verwendet werden. Es können jedoch auch andere elastische Kunststoffe eingesetzt werden, deren Druck- und Verschleißfestigkeit ausreichend hoch ist.Polyurethane (PUR), for example, can be used as plastic. However, it is also possible to use other elastic plastics whose compressive strength and wear resistance are sufficiently high is.

Die Endwindungen der Feder sind nicht ummantelt, damit eine möglichst genaue Parallellage bei vollständigem Auflageumfang möglich ist.The end turns of the spring are not sheathed so that one as precise a parallel position as possible with the entire circumference of the print run is possible.

Die Wandstärke der Ummantelung ist auf den verwendeten Kunststoff und die Drahtstärke der Feder abgestimmt. Sie kann z.B. den halben Federdrahtdurchmesser betragen.The wall thickness of the sheathing is matched to the plastic used and the wire thickness of the spring. You can z. B. be half the spring wire diameter.

Die Ummantelung kann bei der Federhex stellung auf verschiedene Weise erfolgen. So kann z.B. der Federdraht mit einem aufgeschobenen Kunststoffschlauch versehen werden. Es ist aber auch möglich, die Ummantelung durch Tauchen oder durch Spritzen herzustellen. The sheathing can be done in various ways with the Federhex position. For example, the spring wire can be fitted with a Plastic tubing can be provided. But it is also possible to produce the sheathing by dipping or spraying.

Der Kunststoffüberzug dämpft die Eigenschwingungen der Feder. Bei Blockbeanspruchung wird die Schwincungsanregung erheblich vermindert. Hierdurch wird die Wahrscheinlichkeit von Federbrüchen stark herabgesetzt.The plastic coating dampens the natural vibrations of the spring. When the block is loaded, the vibration excitation becomes considerable reduced. This greatly reduces the likelihood of spring breakage.
