| 摘 要： | 针对由物体光路误差导致的齿面像形状畸变现象，利用精确光线追迹算法分析了可能导致齿面像形状畸变的三种因素，明确了齿面像形状畸变的主要误差来源，建立了齿面像形状畸变的判断模型，确立了齿面像形状畸变和齿轮轴线倾斜之间的映射关系，提出了基于齿面像形状畸变特征的物体光路优化方法。最后进行了实验验证，结果表明误差控制在2%左右，证明了所提方法的合理性与正确性。

| Abstract: | Aiming at the tooth surface image shape distortions caused by object optical path errors， three factors that might lead to tooth surface image shape distortions were analyzed by using accurate ray tracing algorithm， the main error sources of tooth surface image shape distortions were defined， the judgment model of tooth surface image shape distortions was established， and the mapping relationship between tooth surface image shape distortions and gear axis inclination was established. An object optical path optimization method was proposed based on the shape distortions of tooth surface images. Finally， the experimental verification was carried out， and the results show that the error ranges are controlled at about 2%， which prove the rationality and correctness of the proposed method. |
