Since the involute profile error of a gear shaft influences its transmission performance, it is desirable to accurately and quickly measure its involute profiles. With the advantages of low cost, universal applicability and in situ detection, a vision measuring method for multiple involute profiles of a gear shaft is developed only using one image in this study. The base circle radius and initial position angle of the involute are obtained by geometrically fitting the involute profile. The correctness and reliability of the method are tested by measuring the pitch deviation of the gear shaft; a specialized experiment is carried out; and the factors affecting the measurement accuracy also are analyzed.
由于齿轮轴渐开线轮廓误差会影响其传动性能,因此需要准确快速地测量其渐开线轮廓。本研究利用低成本、普遍适用性和原位检测的优势,仅使用一张图像开发了一种用于测量齿轮轴多个渐开线轮廓的视觉测量方法。通过对渐开线轮廓进行几何拟合来获得渐开线的基圆半径和初始位置角。通过测量齿轮轴的齿距偏差来测试该方法的正确性和可靠性;进行了专门的实验;并分析了影响测量精度的因素。
