摘要

针对目前椭圆弧齿线圆柱齿轮测量方法的缺乏，设计了一种基于激光位移传感器的椭圆弧齿线圆柱齿轮精密测量装置。阐述了椭圆弧齿线圆柱齿轮的几何形状特征，介绍了激光非接触式测量装置的构成与测量原理，通过对该齿轮多个径向截面轮廓的激光测量，建立齿轮测量截面的轮廓数据模型；对截面轮廓数据模型进行坐标转换，计算出齿轮中间截面的齿距偏差；分析同一轮齿不同截面的齿廓测量数据，计算不同截面分度圆与齿廓交点坐标值，计算出椭圆弧齿线的整体偏差值。该方法能够有效填补曲线齿线圆柱齿轮的测量技术空白，且具有较高的测量精度和效率；其同样也适用于其他圆柱齿轮测量。

Abstract

Aiming at the lack of measurement methods for ellipsoidal arc-toothed cylindrical gears， a precision measuring device based on laser displacement sensor for elliptical arc-toothed cylindrical gear is designed. The geometric shape feature of the elliptical arc-toothed cylindrical gear is expounded， the composition and measurement principle of the laser non-contact measuring device are introduced， and the contour data model of the gear measuring section is established by laser measurement of the multiple radial cross-section profiles of the gear. The coordinate transformation of the cross-section contour data model is carried out to calculate the pitch deviation of the middle section of the gear. The tooth profile measurement data of different sections of the same tooth are analyzed， the coordinate values of the intersection points of the different section index circle and the tooth profile are calculated， and the overall deviation of the elliptical arc tooth is calculated. The method can effectively fill the measurement technology blank of the curved toothed cylindrical gear， and has high measurement accuracy and efficiency; it is also suitable for other cylindrical gear measurement.
