摘　　要：提出运用等角坐标测量法,解决以螺旋曲面为工作母面的零件廓形误差的精密测量问题.采用等角采集特征线上坐标值,运用齿轮测量中心采集螺旋曲面的特征线数据,并对采集的数据进行测头半径补偿;然后,将补偿后的坐标值按照螺旋曲面相关特征线误差的定义进行评定,从而实现对螺旋曲面质量的评价.ZA型传动蜗杆的实例检测表明,该方法能够表征螺旋曲面的质量,满足精密测量要求.In order to solve the problem of difficulty in precision measurement of the spiral surface profile as the working generatrix,a method using equiangular coordinated measuring was put forward.The coordinate value in the characterized curves is collected using the concept of equiangular and the data of characterized curves for spiral surface are collected using the gear measuring center to compensate the coordinate value of data for probe according to the definition of the corresponding characterized curve error for spiral surface to achieve the quality evaluation of the spiral surface.The case study of measuring ZA type worm gear has shown that the method is able to evaluate the quality of the spiral surface and meets the required precision measurement.
