摘要:

传统的传动误差动态测试系统采用光栅作为角度传感器,而高精度光栅价格昂贵且进口受限,针对该情况,采用拥有自主知识产权的时栅位移传感器,通过时间序列模型将时栅由绝对式信号转化为增量式脉冲信号。结合成熟的全微机化齿轮机床精度检测分析系统(FMT系统)对滚齿机进行了传动误差动态测量,准确度达到0.137%,实现了预期目标。

Abstract:

Optical gratings are applied to traditional transmission error dynamic measurement system as angle detecting sensors, but high-precision optical gratings are expensive and imported restrictedly.In view of this situation, a time grating, the novel displacement sensor of proprietary intellectual property rights, is invented. Absolute displacement signal of time grating is converted into incremental pulse signal with time series models. and the experiment results prove that accuracy of measurement can achieve
0.137% by using sophisticated FMT test transmission error of gear-hobbing machine, so the desired schematic design has been obtained.
