采用光栅式传动仪对一台Neles 型磨齿机展成链和分齿链精度进行了测量。应用一种改进的ARMA 谱估计法对所测得的展成链误差源进行了精确的诊断。同时采用信号处理技术成功的组合成传动链全综合误差,该项误差对研究传动链误差对被磨齿轮精度和工作性能的影响有着重要意义。一、前言在参考文献[1]中已对滚齿机差动链误差的测量与谱分析进行了探讨。本文将讨论Neles 型磨齿机传动链误差分析和诊断的方法。采用包括一个圆光栅、一个长光栅传感器(置于圆工作台上和与工作台平移平行的位置上),或两个圆光栅传感器(置于圆工作台和A 轮轴端上)的传动仪对一台Neles 型磨齿机的展成链和分齿链误差分别进行测量(图1)。同时研制成传动链误差谱估计和合成的信号处理软件。
Using a raster-type gearing machine, the precision of chain and splitter chain of a Neles-type grinding machine was measured. An improved ARMA spectral estimation method is used to make an accurate diagnosis of the measured generator chain error sources. At the same time, the signal processing technology is used to successfully combine the total error of the transmission chain. This error is of great significance for studying the influence of the transmission chain error on the precision and working performance of the worn gear. I. Introduction In the reference [1], the measurement and spectrum analysis of the differential chain error of hobbing machine have been discussed. This article will discuss the Neles type grinding machine drive chain error analysis and diagnosis methods. A gear pair including a circular grating, a long grating sensor (placed on a circular table and parallel to the table), or two circular grating sensors (placed on a circular table and A) Spread chain and splitter chain error of a Neles type grinding machine were measured separately (Figure 1). At the same time developed a transmission chain error spectrum estimation and synthesis of signal processing software.
