摘要: 由于对齿轮进行鼓向修形可以有效缓解不对中故障对系统的影响,改善啮合状态,提升传动的平稳性.因此,基于轮齿承载接触分析理论建立考虑轮齿修形以及不对中的啮合特性分析模型,并通过ANSYS对模型的有效性进行了验证;基于本文模型分析了不同接触状态下的齿轮副时变啮合刚度与接触应力;最后以降低齿面接触应力为优化目标,对不对中齿轮副的鼓向修形量进行了优化.本文方法在保证计算精度的前提下极大地提升了计算效率,可为不对中齿轮副的修形优化设计提供理论依据.

关键词: 不对中, 齿轮修形, 啮合刚度, 接触应力, 修形优化

Abstract: The effect of the misalignment can be alleviated effectively by applying proper lead crown relief so that the contact state and the transmission stability can be improved. An analysis model considering gear tooth modification and misalignment is established based on the theory of loaded tooth contact analysis, and the validity of the model is verified by ANSYS. The time-varying mesh stiffness and contact stress of the gear pair under different contact states are analyzed. Finally, with reducing the contact stress of the tooth surface as the optimization objective, the quantity of the lead crown relief of the gear pair is optimized. The calculation efficiency is greatly improved under the premise of ensuring the calculation accuracy. The study provides a theoretical basis for the optimization of tooth modification for gears with misalignment.

Key words: misalignment, tooth modification, mesh stiffness, contact stress, modification optimization
