摘　　要：针对圆柱斜齿轮,提出了一种基于CATIA自带宏程序的精确建模方法。在分析渐开线形成机制、推导渐开线方程与齿面方程、设计齿轮参数的基础上,建立了一个右旋圆柱斜齿轮的最终模型,并对建模精度进行了评价。结果表明,这种建模方法理论正确、建模精度较高、简便易行,能够为圆柱斜齿轮的有限元分析、数控加工仿真等研究提供便利。In order to explore the precise modeling and evaluation method of cylindrical helical gear,a precise modeling method based on CATIA macro program is proposed.Based on the analysis of the formation mechanism of involute,the derivation of involute equation and tooth surface equation,and the design of gear parameters,a final model of right-handed cylindrical helical gear is established,and the modeling accuracy is evaluated.The results show that the modeling method is correct in theory,high in modeling accuracy,and simple and feasible in operation.It is helpful to the research of the finite element analysis and NC machining simulation of cylindrical helical gear.
