Abstract: Planetary gears are very popular as a power transmission and extensively used in in a variety of industrial fields like automobiles, helicopters, aircraft engines, heavy machinery, and a variety of other applications. Despite their advantages, negative impacts on customer perception of quality from noise and vibration are ongoing issue. The noise induced by the vibration of planetary gear systems remains a key concern. Therefore in recent years to reduce gear vibrations different techniques have been proposed. In this paper the experimental work is carried out to study the effect of planet phasing on vibrations of planetary gear set. For this purpose experimental set up is built and trials were performed for two different arrangements i.e with phasing and without phasing. And it is seen that noise level and resulting vibrations were reduced by planet phasing arrangement. So from the experimental results it is observed that by applying the meshing phase difference one can reduced planetary gear set vibrations and noise.
