本文介绍用三坐标测量机测量蜗轮齿形误差的方法,即分析了用三坐标机测量蜗轮齿形误差的特点,组合其测量程序,把在距中间平面一个导圆柱半径的截面上测得的轮廓数据同渐开线理论标准数据相比较,得到了该截面的蜗轮齿形误差。经多次实测表明,该法效率高、操作简便、精度高、可直接得到测量结果、是一种有发展前途的方法。 This article describes the use of CMM to measure the worm gear tooth error method, that is, the use of CMM to measure the characteristics of the worm gear tooth error, combined with its measurement procedures, the distance from the middle plane of a cylindrical radius of the cross section measured Compared with the standard data of involute theory, the profile error of the worm gear is obtained. After many actual measurements show that the method is efficient, easy to operate, high precision, can be measured directly, is a promising method.
