摘　　要：为了提高在机测量齿廓偏差的测量精度,提出了一种可用于实际工况下的测头径向误差提取方法。以标准渐开线直齿轮为研究对象,根据极坐标测量原理以及齿廓偏差计算原理,建立一个以齿廓偏差最小为目标函数,以测头径向误差为变量的最优化模型。求出在实际工况下的测头径向误差,机床系统补偿后对渐开线斜齿轮进行测量,将测量结果与三坐标测量仪检测的结果进行对比,得出测头径向误差求解的合理性。In order to improve the accuracy of tooth profile deviation in machine,a method which can get the radial error based on the actual working condition is proposed. According to the principle of polar coordinates measuring and tooth profile deviation calculation,an optimization model with purpose of minimum tooth profile and variable parameter of radial error is established based on the object of standard involute spur gear.After resolving this radial error and compensating the machine with the error,a helical involute gear is measured and the measured result is compared with the testing result of the three coordinate of the testing results of the three coordinate measuring instrument,the rationality of the radial error solving of the measuring head is obtained.
