摘要

摘要: 针对现有修形齿轮三维建模存在操作复杂、建模精度低等问题,以齿轮几何原理为基础,推导出圆柱斜齿轮作齿形、齿向全鼓形修形的齿面拓扑解析方程,采用数值模拟方法对拓扑齿面进行离散。在CATIA V5 R20环境中分别利用曲面扫掠和逆向工程两种方法对修形齿面三维建模,并根据AGMA标准对建模齿面的齿形、齿向精度进行评价。结果表明,基于逆向工程的齿面重构模型理论建模精度为0级。

Abstract: In order to solve the problems of complex operation and low modeling accuracy in the process of 3D modeling for the modification of gear tooth, the analytical equations of topological tooth surface were deduced for cylindrical helical gear with profile modification and lead modification based on the principle of gear geometry. The topological gear tooth surfaces were represented by the numerical simulation method. The method of spline curves scanning and reverse engineering in the software of CATIA V5 R20 were applied to establish the 3D modeling for modified tooth. The accuracy estimation for modeling the tooth profile and lead modification was evaluated according to the AGMA standard. The results show that modeling accuracy grade of 0 for the reverse engineering method of the tooth surface reconstructed can be obtained.
