【 摘 要 】

How to reduce the influence of poor meshing quality caused by the meshing misalignment of reducer gear pair, a noval micro gear modification strategy based on genetic algorithm is proposed in this paper. The system simulation model of speed reducer gear pair was established by Romax firstly, and the influence of poor meshing quality from the meshing misalignment of reducer gear pair are analyzed, which was optimized by using the method of noval micro gear modification strategy based on genetic algorithm. Modeling analysis demonstrates that the sound pressure level decreased by 3.6 dB by using the method of micro gear modification strategy and the overall noise peak disappeared, vibration noise was effectively improved after modification.
