摘要
根据弧齿圆柱齿轮加工原理及其齿面方程,利用UG/Open Grip二次开发语言在UG中完成齿轮的参数化建模,并实现齿轮副的装配。应用ADAMS对齿轮副进行动力学仿真,得到其在传动过程中部分参数特性曲线并对其进行分析。鉴于目前关于弧齿圆柱齿轮的研究没有成熟的动力学分析成果及计算理论,故将分析结果与同样参数的直齿、斜齿圆柱齿轮的理论计算值进行对比。结果表明:三者周向力、径向力及法向力比较接近,弧齿轮副的轴向力呈对称分布,虽然瞬时值较大但其平均值接近于零。研究结果为弧齿圆柱齿轮的动态特性研究和参数优化提供了技术支撑和理论指导。
Based on the processing principle of cylindrical gear with curvilinear shape teeth and the tooth surface equation,the parametric modeling of gear is completed with the secondary development language of UG / Open Grip and the gear pair is assembled in the UG. Using the ADAMS for dynamic analysis of the gear pair,the parameters characteristic curve of gear pair in the process of transmission is got and analyzed.Since there isn＇t mature theory of dynamic analysis and computational formula about cylindrical gear with curvilinear shape teeth in the current study,the analysis results of cylindrical gear with curvilinear shape teeth are compared with the theoretical calculation values of spur gear and helical cylindrical gear with the same parameters in this paper. The results showed that the circumferential force,radial force and axial force of spur gear,helical cylindrical gear and cylindrical gear with curvilinear shape teeth are almost the same.The axial force of the gear with curvilinear shape teeth is symmetrical distribution. Although the instantaneous value is larger,its average value is close to zero. The results of the study can provide technical support and theoretical guidance for dynamics research and parameter optimization of the cylindrical gear with curvilinear shape teeth.
