초록

This study presents a microgeometry-based design method for optimizing the transmission error (TE)waveform of a planetary gear system to reduce noise and vibration. Using ROMAX parametric analysis, lead and involute modifications were evaluated to reduce the effects of misalignment and higher-order harmonic interference. The optimized design reduced the RMSE relative to an ideal sinusoidal TE waveform, reduced peak contact stress, and improved the dynamic behavior of both the sun-planet and ring-planet contacts.
