孔中心距的位置精度,在很大程度上是影响整体装配和轴传动质量的关键。过去,由于缺乏行之有效的测量工具,对这方面的研讨比较少,所以关键问题一直得不到很好地解决。偶而,也有个别单位无法避免对孔中心距的测量,又嫌用一般游标卡尺测量至少要进行三次测量和三次计算,容易产生差错,既麻烦又不 The location accuracy of the hole center distance is, to a great extent, the key to the overall assembly and shaft drive quality. In the past, due to the lack of effective measurement tools and few studies in this respect, the key issues have not been well resolved. Occasionally, there are individual units can not avoid the measurement of the hole center distance, but also with the general measurement of the general caliper at least three measurements and three calculations, prone to error, both troublesome
