| 摘 要： | 滚珠丝杠(副)导程误差是评价滚珠丝杠精度的重要参数之一。对于导程误差值,可用JB3162。1,2,3—82和ISO179E(草案)标准进行测量、评定及验收。而对导程误差进行频谱分析是为分析产生导程误差的误差源,为提高滚珠丝杠的加工精度和使用精度提供参考。 有关滚珠丝杠导程误差频谱分析的实例,已分别在文献1]、2]中作过介绍,本文将在它们的基础上,进一步讨论滚珠丝杠导程误差频谱分析的几个问题。 一、频谱与加工误差的关系 滚珠丝杠的导程误差主要由局部性误差、周期性误差和渐进性(累积性)误差三部分构成。若把它们写成导程l的函数y(l)的话,则

| Abstract: | The relationship between the frequency spectrum of ball-screw travel error and the machining error is discussed. It has been found that the frequency spectrum depends directly on both the periodical error and local error. The techniques for equitime spaced and equitravel spaced samplings are discussed and the sampling frequency of the latter is given. The application of the spectrum array is also discussed. |
