摘 要: 根据齿轮啮合原理 ,建立了轮齿的精确齿形。系统探讨了加载位置、轮缘厚度、周向齿数的确定方法 ,分析了滚刀顶部圆角对齿根应力的影响 ,提出了两类平面问题的判据并予以验证。在此基础上 ,创建了精确的二维和三维有限元模型 ,并将计算结果与各类权威标准进行对照 。 Exact modeling of gear teeth is based on meshing t heory. After synthetically studying the effects of loading positions, rim thickn ess, circular pinion numbers and fillet radii of gear hob on root section stress es, a judging formula of plane stress and plane strain is proposed and verified, then 2D and 3D FEM models are accurately established. The results show that our method is reliable and correct according to the comparisons with the results of authoritative methods.
