Influence of Torsional Vibrations of a Gear Train System on the Tooth Load

Abstract

In order to investigate the influence of dynamic behaviors of a gear system with many degree of freedom on the tooth load, a new method to measure quantitatively the dynamic increment in the tooth load is presented. Then, by using this method, the dependency of the natural frequencies of the gear system on the dynamic increment in the tooth load is investigated experimentally and theoretically under two different operating conditions. As the result, it is made clear that, under a regulated operating condition, the dynamic increment in the tooth load is dominated by a specific natural frequency of the gear system and on the other hand, under a rough operating condition, the dynamic increment is closely connected with plural natural frequencies of the gear system.
