<p>Planetary gear set has multi planetary pinions between sun gear and ring gear, and it meshes at the several points simultaneously. Therefore, it is difficult to predict the mesh excitation force of the entire planetary gear set, and it is very difficult to design vibration and noise performance.<br>This paper proposes a design method that focused on the mechanism of the mesh excitation force about the planetary gear set. This method designs the optimum specification by analyzing the vibration behavior and the mesh excitation force.<br>As practical applications, the optimum specification is determined by analyzing the mesh excitation force of a sequentially phased (SP) planetary gear set and an in-phase (IP) planetary gear set, and considering the vibration mode in focused frequency. As a result, this method is verified by actual transmission tests, the gear noise is improved by changing the gear specification that contains different mesh phasing.</p>
