摘要: 为了获得真实的面齿轮过渡曲面,推导了当插齿刀顶部为圆角时的过渡曲面方程.针对面齿轮齿面结构的特殊性,提出了有限元模型的"网格筛选法",纠正了单元形状的扭曲现象.以轮齿接触分析(TCA)为基础,采用三维接触有限元方法计算了面齿轮副的啮合过程中及其它参数变化时弯曲应力的变化.计算发现名义压力角参数和面齿轮轴向调整对弯曲强度都有重要影响.

Abstract: The fillet surface equation of face gears was presented when the top of the shaper tooth was rounded.A 'mesh filter method' was proposed in view of the particularity of face-gear's structure,and the distortion of the element shape was corrected.Based on tooth contact analysis(TCA),the variation of bending stresses during the cycle of meshing was computed with 3-Dcontact finite element method when some parameters changed.The results indicate that both of the nominal pressure angle and shaft adjustments of face-gear have significant influence on the bending strength.
