摘　　要：采用对称圆角和非对称圆角来设计滚刀刀顶,推导了滚刀非对称圆角半径的计算公式,通过ANSYS的APDL语言建立了滚刀范成加工渐开线齿轮的参数化有限元模型。结果表明,选择最佳对称圆角滚刀可使齿根弯曲应力降低8.3%,而采用非对称圆角滚刀可以使齿根弯曲应力降低12.4%。The symmetrical and asymmetrical fillet are adopted to design the hob top. The formula of the asymmetric fillet radius is derived. Parametric finite element model of hob envelope cutting involute gear is founded by ANSYS APDL language. The results show that, tooth root bending stress is reduced by 8 % by choosing the best symmetrical hob top fillet and the root bending stress is reduced by 11% by using the asymmetrical hob top fillet.
