摘　　要：利用CATIA软件建立斜齿轮防滑差速器齿轮的参数化几何模型,该模型能根据输入的参数进行快速的修改,大大提高了设计质量和效率。将建立好的齿轮几何模型简化后,用有限元分析法对其进行啮合接触分析。分析结果表明设计的齿轮的齿面接触应力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,最大弯曲应力在齿轮根部位置,与实际情况相符,并且小于许用值,设计满足要求。The parameterized geometric model of gear of helical gear limited slip differential is built by using CATIA software,which can modification quickly according to the input parameters that improved the design quality and efficiency greatly. After simplifying the geometric model of gears,its meshing contact analysis is carried out by using the finite element analysis method. The results show that the surface contact stress of design gear is far less than the material allowable contact stress,so gears won＇t appear the contact fatigue damage,and the maximum bending stress position at gear root,and that is consistent with the actual situation and the maximum bending stress is less than the material allowable bending stress,so the design meets the requirements.
