摘　　要：采用Solidworks建立直齿锥齿轮三维模型,通过Solidworks软件和Ansys软件数据接口将锥齿轮三维模型导入Ansys软件中,考虑润滑的影响,在Ansys软件中进行直齿圆锥齿轮的应力分析。将齿轮弹流数值计算的油膜压力作为加载项,同时将轮齿接触线扩展成接触面,将线载荷转化成面载荷,计算得到轮齿应力值。与其他计算方法相比,该方法计算结果与真实工作环境下产生的轮齿应力值之间的误差最小。对提高轮齿强度、改进和优化齿轮设计具有一定的参考价值。The 3D model of bevel gear was established in the Solidworks and moved into Ansys software through the data interface of Solidworks and Ansys software.Considering the effect of lubrication,the stress analysis of spur bevel gear was made in the Ansys.The oil film pressure by elastohydrodynamic numerical calculation acted as a pressure loading,the line contact of gear was expanded to surface contact,and the line load was translated to surface load,the gear load stress was calculated.Compared with other calculation methods,this method has the least relative error to the real stress value in working condition.This research has the certain reference value for improving the gear strength and optimizing the gear design.
