测量外螺纹螺距的方法较多,在万能工具显微镜、丝杆检查仪等上均可测量。但测量内螺纹螺距就比较困难。尤其是用于精密数控传动的滚珠丝杆副,其螺纹牙型由双圆弧构成,对螺距的要求较为严格,这种螺母的测量就更为困难。这里介绍一种简易可行的测量方法,供参考。可以在卧式万能测长仪上进行(图1)。只要

There are many ways to measure the thread pitch of the external thread, which can be measured on the universal tool microscope, screw tester and the like. However, it is difficult to measure the internal thread pitch. Especially for precision CNC transmission ball screw pair, the thread form by the double arc, the more stringent requirements on the pitch, the nut measurement is even more difficult. Here is a simple and feasible measurement method for reference. Can be carried out in the horizontal universal length measuring instrument (Figure 1). as long as
