渐开线齿轮UG参数化设计的几个关键问题

摘要

This paper establishes involute, tooth root transition curve symmetrical equations, accurately calculates the value of parametric equations and boundaries of the gear teeth of different forms of modeling, provides back-bevel gear cone base plane coordinate system to establish the baseline method. The solution of the parameters of the key problems ensures the authenticity of the gear tooth profile, avoids the loss of asymmetry and the problem parameters, and achieves a gear design of the real model parameters.%建立渐开线、齿根过渡曲线对称方程，精确计算方程参变量取值及不同建模形式的分界齿数，提供锥齿轮背锥基准平面与基准坐标系建立方法，参数化关键问题的解决保证了齿轮齿廓曲线的真实性，避免了齿廓不对称和参数丢失问题，真正实现了齿轮建模的参数化设计．
