摘　　要：针对传统基于三坐标测量机的接触式测绘方法无法反求小模数齿轮参数的问题,基于齿轮影像测量得到的齿廓测点坐标数据,给出了基于最小二乘原理的基圆半径反求模型和优化求解算法。反求出基圆半径后,结合影像测量得到的其他数据,可反求出齿轮的其他各项参数。通过齿轮泵实例证明,该反求方法是可行的,该研究将有助于提高通用航空部/附件的维修水平。For the problem that fine-pitch gear parameters can＇ t be got by the contact measuring method based traditional three- coordinates measuring machine, the inverse calculation model of radius of basic circle based on least square principle and its sol- ving algorithm have proposed by using the coordinate of points on tooth profiles from the image measurement. After figuring out the radius of basic circle, the other parameters of gear can be got by using the other data from the image measurement. Gear pump case analysis show that the proposed inverse calculation method is effective. The study can help the general aviation part mainte- nance.
