Abstract

A new method for calculating the three dimensional vibration behavior of a multi–stage helical gear system including a gearbox has been developed. This method utilizes three dimensional multi-stage gear vibration analysis and FEM analysis. The calculated three-dimensional vibration of gears is used in a FEM model, which gives the vibration responses of the gearbox. The calculated and measured eigen frequencies and vibration responses of the gearbox agree well. For obtaining precise vibration responses of the gearbox, therefore, it is shown to be effective to consider the modeling of gear shaft, gear meshing, bearing and leg of gearbox in FEM analysis.
