摘　　要：汽车转向器摇臂轴非圆齿扇是一种锥面上端截面的变位系数随端截面位置不同而变化的结构复杂的齿轮,目前还没有专用的测量软件。本文提出了一种汽车转向器摇臂轴非圆齿扇齿廓误差测量方法,将用齿廓法线法计算得到的理论齿廓坐标导入Kligenberg P26中的Sprocket profile模块对已知理论齿廓坐标的非圆齿扇进行测量。根据非圆齿扇齿条副的啮合特性,计算并绘制出非圆齿扇齿条副的啮合瞬心点;根据willis定理计算非圆齿扇的齿廓,并用仿真软件绘制齿廓;为了更直观的显示非圆齿扇齿齿面的误差,将齿面网格划分,并将同一齿槽的若干截面整合为一个完整的齿面误差模型。The non-circular gear sector of the automobile steering gear rocker shaft is a complex structure gear whose displacement coefficient of the upper cross section of the tapered surface changes with different end cross section positions.There is currently no dedicated measurement software.This paper presents a method for measuring the tooth profile error of the non-circular gear sector of the rocker arm of the steering gear of an automobile.The theoretical tooth profile coordinates calculated by the tooth profile normal method are imported into the Sprocket profile module in Kligenberg P26 to measure non-circular gear sector with known theoretical tooth profile coordinates.According to the meshing characteristics of the non-circular gear sector rack pair,the instantaneous center of meshing of the non-circular gear sector rack pair is calculated and drawn;the tooth profile of the non-circular gear sector according to the Willis theorem is calculated,and the tooth profile by using the simulation software to is drawn;the error of the tooth surface of the non-circular tooth is intuitively displayed,the tooth surface mesh is divided,and several sections of the same tooth groove is integrated into a complete tooth surface error model.
