摘　　要：研究了全工序法准双曲面齿轮,即大轮成形法、小轮螺旋成形法加工的齿面建模、加工切削仿真和有限元分析。借助坐标变换和空间啮合理论,推导小轮齿面方程;根据机床调整参数,在CATIA中模拟刀盘和轮坯的展成运动,进行切削加工仿真,建立高精度的齿轮副实体模型;利用有限元软件Abaqus对齿轮副进行接触分析,计算并提取整个啮合过程的齿根弯曲应力和齿面接触应力,为准双曲面齿轮的强度设计提供参考。The tooth surface modeling, cutting simulation and finite element analysis of hypoid gears cut by the completed method is studied, which the wheel gear is cut by the format method while the gear is generated by the duplex helical method. The pinion tooth surface equation can be derived based on the coordinates transformation and spatial meshing theory. According to machine -tool settings of Gleason＇s summary, the high -precision solid model of gear pairs can be established by the cutting simulation of the generated motion between cutter and blank in CATIA software package. By using the finite element software Abaqus to conduct the contact analysis of gears drive, and the tooth root bending stress and the tooth surface contact stress can be calculated and extracted in the entire meshing process, the research results can provide a reference for the strength design of hypoid gear.
