Gearbox improvement aimed at noise reduction
Release Date:29/12/2015
The research work on noise reduction employs different methods to identify the dynamic properties and to discover the dynamically weak parts of gearbox structures. In reality, the effect of these improvements, which are limited by the given gearbox structure, on the overall SOL is of small significance. However, they are important because, after introducing these improvements, the SPL of newly built units varies in correlation with errors of great geometry. The most efficient improvement can be reached when the noise problems is controlled at its very source, which is the tooth contact of meshing gears.
