摘　　要：针对运用理论设计的齿轮进行仿真而运用实际生产的齿轮进行滚检验证测试所造成的评价标准不一致的问题,通过NURBS曲面拟合的方法重新构造真实齿轮面,在CATIA软件中进行了三维模型的构造。利用Abaqus软件对真实齿面的准双曲面齿轮传动误差进行分析,对比真实齿面啮合和纯理论齿面啮合的传动误差,验证了真实齿面误差的存在及其对传动误差的消极影响。改变齿轮的安装误差发现,轴交角误差、小轮安装距误差、偏置距误差和大轮安装距误差对传动误差的影响依次减小,通过滚检机实验验证了真实齿面仿真模型的合理性。Aiming at the inconsistency evaluation standards caused by using the gear designed by theory for simulation and using the gear produced by actual production for roll inspection certificate test,by using the NURBS surface fitting method,the real tooth surface is reconstructed and the construct of the 3D model in CATIA software is carried out.The Abaqus software is used to analyze the error of the hypoid gear transmission of the real tooth surface,and the transmission error of the real tooth surface meshing and the pure theoretical tooth surface meshing is compared,the existence of real tooth surface error and its negative influence on transmission error are verified.Changing the installation error of the gear found that the influence of the shaft angle error,the small wheel installation distance error,the offset distance error and the large wheel installation distance error on the transmission error decreased in turn.The rationality of the real tooth profile simulation model is verified by the rolling machine experiment.
