Abstract

The chain links (1) or toothed elements which make up the chain or toothed belt are of different length. The chain or belt runs on chain or toothed belt wheels (2) with correspondingly different tooth spacing. The number of teeth of all the toothed wheels of the chain drive and the number of chain links is divisible by a whole number (n) and the chain comprises groups of (n) chain links of different length with which groups of (n) teeth of different spacing correspond on the circumference of the chain wheels. The chains and chain wheels or belt and toothed wheels can have circumferential markings to prevent faulty assembly. USE/ADVANTAGE - Chain or toothed belt drive for valves in IC engines is designed for reduced vibration and noise.

Description

Bei den heute üblichen PKW-Motoren kommen für den Nockenwel­ lenantrieb fast ausschließlich Rollenketten- oder Zahnrie­ mentriebe zum Einsatz. Durch den periodischen Zahneingriff entstehen in beiden Fällen Heulgeräusche, die wegen ihres periodischen Geräuschcharakters (Prinzip Lochsirene) aus dem Gesamtgeräusch des Motors herausgehört und als störend empfunden werden.With today's usual car engines come for the cam world lenantrieb almost exclusively roller chain or toothed belt drive systems for use. Through the periodic meshing arise in both cases howling noises because of their periodic noise character (principle siren) from the Total noise from the engine is heard and considered distracting be felt.

Die physikalisch ähnlichen Probleme bei der Reifenprofilie­ rung oder bei der Flügelanordnung von Lüfterrädern werden erfolgreich durch Variation der Teilung über den Umfang und damit Vermeidung oder Reduzierung der Periodizität der Anregung gelöst.The physically similar problems with tire tread tion or the wing arrangement of fan wheels successful by varying the division over the scope and thus avoiding or reducing the periodicity of the Solution solved.

Bei Zahnrad- oder Kettentrieben ist eine solche Lösung im allgemeinen nicht möglich, da jeder Zahn in jede Lücke am Umfang des anderen Zahnrades passen muß. Beim Nockenwel­ lenantrieb ermöglicht jedoch das ganzzahlige Übersetzungs- Verhältnis von 1 : 2 (beim Viertaktmotor), die Zähnezahlen in Gruppen zu unterteilen, innerhalb derer die Zahnteilung unterschiedlich ist. For gear or chain drives, such a solution is in generally not possible, since every tooth in every gap The circumference of the other gear must fit. At the cam world However, the linear drive enables the integer translation Ratio of 1: 2 (for the four-stroke engine), the number of teeth in Subdivide groups within which the tooth division is different.  

So besteht beispielsweise die Steuerkette eines serienmäßi­ gen PKW- Motors aus 126 Gliedern, die über ein kurbelwellen­ seitiges Antriebsrad mit 18 Zähnen und ein nockenwellensei­ tiges Abtriebsrad mit 36 Zähnen läuft.For example, there is a standard timing chain gen car engine from 126 links, which over a crankshaft drive wheel on the side with 18 teeth and a camshaft egg driven gear with 36 teeth runs.

Fig. 1 zeigt die Anordnung von drei Kettengliedern unter­ schiedlicher Länge, die sich am Umfang der Kette 42mal wiederholt bzw. die Zahnteilung, die sich am Umfang der Kettenräder 6- bzw. 12mal wiederholt. Damit wird die Wiederholfrequenz des Zahneingriffs auf 1/3 reduziert (6. Kurbelwellenharmonische anstelle der 18.) und die Schwin­ gungsenergie auf drei Frequenzen verteilt. Der Geräusch­ charakter wird dadurch ähnlich einem Rauschen und ist aus dem restlichen Motorgeräusch nicht mehr herauszuhören. Fig. 1 shows the arrangement of three chain links of different lengths, which is repeated 42 times on the circumference of the chain or the tooth pitch, which is repeated 6 or 12 times on the circumference of the chain wheels. This reduces the repetition frequency of the meshing to 1/3 (6th crankshaft harmonic instead of the 18th) and the vibration energy is distributed over three frequencies. The noise character is similar to a noise and can no longer be heard from the rest of the engine noise.

Ist auch die noch verbleibende 6. Motorordnung störend, so lassen sich die 3 unterschiedlichen Kettenglieder auch noch zu 6 unterschiedlichen Dreiergruppen anordnen (entsprechend den Kombinationsmöglichkeiten der Zahlen 1 bis 3) und mit der gleichen Anzahl von Bauteilen ein höheres Maß an Unregelmäßigkeit erzeugen.If the remaining 6th engine order is also disruptive, so the 3 different chain links can also be used arrange to 6 different groups of three (accordingly the possible combinations of numbers 1 to 3) and with a higher level of the same number of components Generate irregularity.
