Vibration Measurement and Noise Control in Planetary Gear Train

A.R.Mokate, R.R.Navthar

In recent days reduction in noise and vibration are mainly focused by researchers. Vibration and noise generated in the gear train is mainly due to the meshing of gear pair and transmission errors. By minimizing the transmission errors the fluctuation is effective only for certain torque level. In this paper we are using the planetary gear train due to advantages over the parallel shaft gear system. We focused on different angular positions that mean phasing of gear pair by keeping the every individual set unchanged. The vibration and noise in this system are measured by FFT analyzer by phasing and withought phasing arrangement. It was determined that amplitude of vibration were getting changed by phasing arrangement between two gear pair which will help for reduction of noise in planetary gear train.
