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
Ball Screw (Vice) Lead Error is one of the most important parameters for evaluating ball screw accuracy. For lead error values, JB3162.1, 2, 3-82 and ISO179E (draft) standards can be used for measurement, assessment and acceptance. However, the spectrum analysis of the lead error is the source of error for the analysis of the lead error, so as to provide reference for improving the machining accuracy and accuracy of the ball screw. An example of spectrum analysis of ball screw lead error has been introduced in references [1] and [2] respectively. Based on them, this paper will further discuss some problems of ball screw lead error spectrum analysis . First, the relationship between spectrum and machining error Ball screw lead error mainly by the local error, periodic error and progressive (cumulative) error of three parts. If they are written as a function of the lead l (l), then
