Description
Lackdraht mit hohem Reibungskoeffizienten für Spulen der Elektrotechnik Die Erfindung betrifft einen Lackdraht mit hohem Reibungskoeffizienten für Spulen der Elektrotechnik, insbesondere für die Herstellung von Kreuzwickelspulen.Enamelled wire with a high coefficient of friction for electrical engineering coils The invention relates to enamelled wire with a high coefficient of friction for coils in electrical engineering, especially for the manufacture of cross-wound bobbins.
Es ist bekannt, daß die Eignung von Lackdrähten für die Herstellung von Träufelwicklungen. entscheidend von der Oberflächenglätte dieser Lackdrähte abhängt. Bei besserer Oberflächenglätte ist der Draht wesentlich leichter zu verarbeiten und erfordert einen geringeren Wickelraumbedarf. Lackdrähte werden daher seit langem mit einem dünnen Film eines geeigneten Gleitmittels überzogen, indem sie meist vor dem Aufspulen nach Passieren des Drahtlackierofens durch eine Auftragsvorrichtung, z. B. Filz, laufen, die das Gleitmittel selbst, z. B. pflanzliche Öle, oder eine Lösung des Gleitmittels, z. B. gewisse Wachstypen, in organischen Lösungsmitteln auf den Draht aufträgt. Durch dieses Verfahren kann der Reibungskoeffizient der Drahtoberfläche, der bei unbehandelten Drähten etwa 0,2 beträgt, bis auf 0,06 verringert werden.It is known that the suitability of enamelled wires for manufacture of trickling windings. crucially on the surface smoothness of these enameled wires depends. With better surface smoothness, the wire is much easier to process and requires less changing space. Enameled wires have therefore been used for a long time Covered with a thin film of a suitable lubricant, usually before the winding after passing the wire enamelling furnace through an application device, z. B. felt, running the lubricant itself, z. B. vegetable oils, or a Solution of the lubricant, e.g. B. certain types of wax, in organic solvents applies to the wire. By this method, the coefficient of friction of the Wire surface, which is about 0.2 for untreated wires, reduced to 0.06 will.
Im Gegensatz hierzu werden für die Herstellung bestimmter Spulenarten für die Radio- und Fernsehtechnik und für elektronische Geräte Lackdrähte mit hohem Reibungskoeffizienten benötigt. Bei Folgewickelautomaten können die Drahtwindungen durcheinanderfallen, wenn die Drähte zu glatt sind. Besonders kritisch ist auch die Verarbeitung der Drähte zu Kreuzwickelspulen. Bei der Fertigung der sogenannten Honigwabenspulen wird der Draht während einer Spulenrotation um etwa 180° von einer Spulenseite auf die andere verlegt. Die Herstellung solcher Wicklungen gelingt nur, wenn die Drahtwindungen keine zu große Gleitwirkung haben. In der Praxis hat man sich zunächst durch die Mitverwendung von Klebemitteln während des Wickelvorganges oder durch Einsatz von textilbesponnenen Drähten geholfen. Solche Drähte sind teuer, und ihre elektrischen Daten befriedigen nicht immer.In contrast, certain types of coils are used for the manufacture of for radio and television technology and for electronic devices enamelled wires with high Coefficient of friction required. With sequential winding machines, the wire windings mess up if the wires are too smooth. Is particularly critical too processing the wires into cross-wound bobbins. When manufacturing the so-called Honeycomb bobbins move the wire by about 180 ° during one bobbin rotation Coil side moved to the other. Such windings can only be produced if if the wire turns do not have too much sliding effect. In practice you have initially through the use of adhesives during the winding process or helped by using textile-spun wires. Such wires are expensive, and their electrical data are not always satisfactory.
Die vorliegende Erfindung ermöglicht die Herstellung von Lackdrähten mit hohen Reibungswerten für Spulen der Elektrotechnik, insbesondere für die Herstellung von Kreuzwickelspulen in einfacher und zweckmäßiger Weise.The present invention enables the manufacture of enameled wires with high friction values for electrical engineering coils, especially for manufacturing of cross-wound bobbins in a simple and practical manner.
Erfindungsgemäß wird deshalb ein Lackdraht vorgeschlagen, wobei der lackierte Draht mit einem dünnen Film aus Polyglykolen oder Netzmitteln auf der Basis der Alkylphenolpolyäther oder synthetischen Wachsen auf Nitroparaffmbasis überzogen ist.According to the invention, therefore, a magnet wire is proposed, wherein the lacquered wire with a thin film of polyglycols or wetting agents on the Based on alkylphenol polyethers or synthetic waxes based on nitroparaffin is covered.
Lackdrähte dieser Art weisen einen hohen Reibungskoeffizienten auf und können vorteilhaft für die vorstehend genannten Zwecke eingesetzt werden. Von besonderem Vorteil ist die einfache Anwendung auf beliebige Lackdrähte.Enamelled wires of this type have a high coefficient of friction and can advantageously be used for the purposes mentioned above. from A particular advantage is the simple application to any enameled wire.
An Hand eines Beispiels wird die Herstellung eines solchen Drahtes mit hohem Reibungskoeffizienten beschrieben.The production of such a wire is shown using an example described with a high coefficient of friction.
Beispiel Einen lötbaren Polyurethanlackdraht mit einem Reibungskoeffizienten von 0,20 läßt man durch einen Filz laufen, der mit einer 1 o/oigen Lösung von im Handel befindlichem Oxazolin-Wachs in Toluol getränkt ist. Nach der Verdunstung des Lösungsmittels hat der Draht einen Reibungskoeffizienten von 0,42. Er eignet sich gut für die Herstellung von Kreuzwickelspulen.Example A solderable enamelled polyurethane wire with a coefficient of friction of 0.20 is run through a felt with a 1 o / o solution of im Commercially available oxazoline wax is soaked in toluene. After evaporation of the solvent, the wire has a coefficient of friction of 0.42. He is suitable good for the production of cross-wound bobbins.
