利用大型三维设计软件UG进行二次开发，建立了差速器的参数化造型系统，该系统能够根据输入的参数精确而快速地生成差速器齿轮的三维模型，大大提高了设计质量和设计效率．同时，将建立的差速器齿轮三维模型无缝连接到有限元软件中，对差速器齿轮进行静强度分析以及动态接触分析．分析结果表明所设计的行星齿轮和半轴齿轮最大弯曲应力在齿根部位且小于许用应力值，齿面接触应力远远小于材料许用接触应力，因此齿轮不会出现接触疲劳破坏．

Large three-dimensional design software, UG, is used for secondary development to build a parametric modeling system, which can be used to accurately and quickly generate a three-dimensional model for differential gears. The design quality and efficiency are thus improved. At the same time, the model is seamlessly connected to finite element software for static strength analysis and dynamic contact analysis of the differential gear. The results show that the largest bending stress of planet gear and side gear is at the tooth root and lower than allowable stress value. More importantly, tooth surface contact stress is considerably lower than the allowable contact stress of the material, thereby preventing contact fatigue damages.
