摘要

为了减小高速齿轮的振动与噪音，针对齿面传统修形方法中未考虑重合度影响的情况，以及仅考虑减少传动误差幅值对于高速齿轮减振降噪效果不显著的情况，提出了一种考虑重合度的齿面新修形方法，和基于几何接触分析和承载接触分析的啮入冲击力计算方法。基于智能优化算法和提出的新修形方法，建立了以冲击力和承载传动误差幅值最小的优化模型，通过多目标优化得到相应的优化修形量。实例计算结果表明：与传统修形相比，新修形能够更有效的减小承载传动误差波动和冲击力。

Abstract

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.
