摘要
基于齿轮啮合原理,在有限元分析软件ANSYS中采用APDL语言建立了齿轮传动三维参数化有限元模型.依据传热学和摩擦学理论,建立了单个轮齿的本体温度有限元分析模型,利用ANSYS软件求解出单个轮齿的本体温度场.将温度分布作为轮齿的温度载荷,计算轮齿的热变形,求出基于热变形的齿廓最大修形量.此外,依据经验公式,根据轮齿的受载情况计算齿廓的最大修形量.结合修形理论,得出了热弹耦合修正的渐开线齿廓修形曲线方程.通过ANSYS接触分析验证修形效果,得到修正后的修形曲线方程.
Based on principles of gear meshing,3D parametric finite element model of the involute gear was built using the ANSYS parametric design language（APDL）.The finite element model of single gear tooth body temperature was established,and then the bulk temperature field of gear tooth was obtained by the ANSYS,on the basis of heat transfer and friction theories.Taking the temperature distribution as the temperature load of the gear,thermal deformation was calculated by the maximum amount of modification for an involute tooth profile.Besides,the maximum amount of modification in terms of the force load on the gear was also calculated according to empirical formulas.Finally,the modification curve equation was revised through thermo-elastic coupling analysis combined with the modification theory and then verified through the ANSYS contact analysis.
