高速齿轮传递误差和啮入冲击的激励模拟及齿面优化修形

Aiming at cases of influence of contact ratio being not considered in traditional tooth modification methods, and noise and vibration reduction effect being not significant only considering reduction of amplitude of loaded transmission error (ALTE) for high speed gears, a new tooth surface modification method considering contact ratio or overlap ratio, and an approach for calculating mesh-in impact force based on the tooth contact analysis (TCA) and the loaded tooth contact analysis (LTCA) were proposed. Ultimately, based on the intelligent optimization algorithm and the proposed tooth surface modification method, an optimization model was established to minimize ALTE and mesh-in impact force, and the optimal tooth surface modification values were determined through the multi-objective optimization. The actual example calculation results showed that compared with the traditional tooth surface modification, the proposed new method can be used to effectively reduce fluctuation of loaded transmission error and mesh-in impact force.
