A new method for predicting the vibration and noise of a total gear system, including not only multi-stage gear pairs but also shafts, pedestals, and a gearbox was developed. The method consists of three separate analyses: three-dimensional gear-vibration analysis, FEA (finite element analysis) of gearbox vibration, and BEA (boundary element analysis) of the sound field. To verify the effectiveness of the method, the authors experimented with a second-stage helical reduction gear apparatus. These measurements agreed well with the corresponding calculated levels by developed analysis method. It can thus be concluded that the method can accurately predict vibration and noise and sufficiently assess the noise radiated and propagated through air. Furthermore, gear vibration and sound-pressure level was measured to figure out the influence of four design parameters: output torque, type of coupling, viscosity of gear oil, and clearance between bearing outside and housing. In this paper, how to introduce the influence of these parameters in vibration and sound-radiation analysis of a gear system was studied.
