The complex subject of gearing technology requires continuous training of engineers. In cooperation with the FVA, Eurotrans has launched a comprehensive training course on the geometry and calculation of gearings. This seminar is addressed to a European audience and is organized by the FVA in Munich in close cooperation with the Gear Research Centre (FZG) of the Technical University of Munich.
