Abstract

The components have blanks for adhesive bonding provided on a side with hardened self bonding wire and on another side with non-hardened self bonding wire. The components are formed from a packet of plates that are produced by stamping and are firmly connected with one another by the self bonding wire. The self bonding wire is hardened under pressure and temperature, where the temperature is set to 270 to 320 degree Celsius during a hardening duration of 20 seconds. A thickness of the self bonding wire is approximately 1 micron.

Nockenwellen von Brennkraftmaschinen werden meistens über eine Kette oder einen Zahnriemen von Kurbelwellen angetrieben und dabei in einem geschlossenen Regelkreis kontinuierlich verstellt, wobei typische Verstellbereiche bei 40 bis 60° Kurbelwinkel liegen. Einzustellende Kurbelwinkel sind in Kennfeldern hinterlegt. Verstellungen erfolgen z. B. hydraulisch, gespeist aus dem Motorölkreis über ein elektrisch betätigtes Steuerventil und ermöglichen optimierte Ventilsteuerzeiten über die Parameter Motorlast und -drehzahl. Je nach Motorkonzept und Anzahl der Versteller ist so eine deutliche Absenkung von Kraftstoffverbrauch und Abgasemissionen sowie eine Steigerung von Leistung und Drehmoment erreichbar.camshafts of internal combustion engines are mostly via a chain or a timing belt driven by crankshafts while in a closed loop continuously adjusted, with typical Adjustment ranges are at 40 to 60 ° crank angle. adjusted Crank angles are stored in maps. Adjustments are made z. B. hydraulically, fed from the engine oil circuit via a electrically operated control valve and allow optimized valve timing via the parameters engine load and speed. Depending on the engine concept and number of adjusters is such a significant reduction in fuel consumption and exhaust emissions as well an increase in power and torque achievable.

Backlack ist ein warmvernetzendes Epoxydharzsystem, welches bei vollständiger Vernetzung verklebt und elektrisch isoliert (Schichtstärke 4–6 μm). Es wird eingesetzt zum Verkleben von Elektroblechen für Motoren, Generatoren, Transformatoren, lamellierten Magnetkernen etc. Die Backlackschichten der Einzelbleche verbinden sich unter Druck und Temperatureinfluss (siehe: http://www.tschopptech.ch/Moeller_Verlag.pdf ).Backlack is a thermobonding epoxy resin system, which adheres when fully crosslinked and electrically isolated (layer thickness 4-6 microns). It is used for bonding electrical steel sheets for motors, generators, transformers, laminated magnetic cores, etc. The baking enamel layers of the individual sheets combine under pressure and temperature influence (see: http://www.tschopptech.ch/Moeller_Verlag.pdf ).

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung wird der Backlack unter Druck und Temperatur ausgehärtet für Bauteile mit innerer Dichtheit. Bei einer Aushärtdauer von 20 sec. soll die Temperatur 270–320°C und bei einer Aushärtdauer von 30 sec. soll die Temperatur 250–300°C betragen.According to one Another preferred embodiment of the invention is the baked enamel cured under pressure and temperature for components with inner tightness. At a curing time of 20 sec. the temperature should be 270-320 ° C and at a curing time of 30 sec., The temperature should be 250-300 ° C.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist die Schichtdicke des Backlacks zwischen 0,5 und 1,5 μm, vorzugsweise ca. 1 μm, so dass das Risiko von Vorspannungsverlusten an Paketen als Schraubverbänden zwischen Rotor und Nockenwelle reduziert ist.According to one Another preferred embodiment of the invention is the layer thickness of the baked enamel between 0.5 and 1.5 μm, preferably approx. 1 μm, so the risk of bias losses on packages reduced as screw connections between rotor and camshaft is.
