齿轮传动误差峰峰值最小化的拓扑修形优化研究OA北大核心CSTPCD

In order to meet the requirements of low noise,small vibration and high transmission accuracy of the gear transmission system,this paper proposed a gear topological modification and optimization method.Firstly,the gear is modified in the tooth profile and tooth-leading directionof the involute helical gear tooth based on the modification superposition curve.A topologically modified gear tooth surface formationmethod is proposed.Then,taking the minimum peak-to-peak value of gear transmission error as the optimization goal,the parameters of the topologically modified gear tooth surface formation method were optimized with the genetic algorithm,and the optimal modification parameters of the topologically modified gear tooth surface were obtained.Finally,the topologically modified gear and the standard gear are compared,and the tooth surface load and tooth root stress distribution of the gear before and after modification are analyzed,and the effectiveness of the proposed topological modification and optimization method is verified.
