| 摘 要： | 该文研究了滚珠丝杠滚道几何参数的测量和计算方法。该算法将采集的数据点分割成滚道数据域和丝杠外径数据域,分别对这2个数据域进行拟合处理,得到滚道几何参数,并给出了评定方法。实验采用非接触式测量方式,通过采集丝杠滚道法向误差数据,实现对丝杠各个滚道参数的测量。该方法可以实现丝杠中径、丝杠外径、螺距、滚道跳动、滚道形状误差的测量与分析,与繁琐的手工测试手段相比,具有采集的数据点多、效率高的优点,得到的测量结果能更好地反映丝杠型面误差。

| Abstract: | The measurement and calculation method of the ball track geometry of a ball screw shaft is studied here.The data collected are divided into ball track data and ball screw shaft outer diameter data in the algorithm.These two data are fitted separately,the ball track geometric parameters are achieved and the evaluation method is given.Using the non-contact measurement method and by collecting the error of the ball track cross section data of a ball screw shaft,all ball track parameters are obtained in the exp... |
