滚珠丝杠副作为传动元件和定位元件广泛地应用于各种机械和量仪中,尤其是节能技术和数控机床的发展,对滚珠丝杠的需要量越来越多,同时对精度的要求也越来越高。在滚珠丝杠副使用中,人们发现原来评定精度的方法不能从整体上反映出螺纹全长范围内的导程误差,也不能直观地反映出滚珠丝杠导程精度与机床定位精度之间的关系,为此日本的吉本勇提出了采用误差回归曲线以及误差波动度来表示丝杠导程误差的方法,这个方法在日本获得了广泛地采用,并形成了JIS标准。国
Ball screw pair as a transmission element and positioning element is widely used in a variety of machinery and measuring instruments, especially energy-saving technology and the development of CNC machine tools, the ball screw needs more and more, while the accuracy requirements Higher and higher. In the use of ball screw, it was found that the original method to assess the accuracy of the whole thread can not reflect the entire length of the lead error, it can not intuitively reflect the ball screw lead precision and machine positioning accuracy For this reason, Japan’s Yoshimoto Yoshihide put forward the method of using the error regression curve and the error fluctuation to express the lead screw lead error. This method has been widely adopted in Japan and has formed the JIS standard. country
