摘要

针对航空发动机附件传动齿轮高温、高转速、重油雾的实际工况，基于磁栅传感器信号4倍细分辨向原理，设计开发了齿轮动态传动误差测试系统。该系统采用磁栅传感器同步测量主动轮和被动轮实时转角，通过NI高速采集卡、磁盘存储阵列和LabVIEW生产者/消费者模式实时采集、存储高速数据。最后，采用数字计数法计算得到齿轮动态传动误差曲线。该系统测量转速可达40 000 r/min，比其他同类测试系统的适用转速提高了1倍，为后续更高转速的附件传动齿轮振动机理分析和齿面的修形设计提供了数据支持。

Abstract

Aiming at the actual working conditions of high temperature， high speed and heavy oil mist of the accessory transmission gear of aero engine， a set of the gear dynamic transmission error test system is designed and developed based on the principle of the quadruple subdivision of magnetic grid sensor. In this system， the real-time rotation angel of the driving gear and driven gear is respectively measured at the same time by magnetic grid sensor， through the high-speed data acquisition， storage devices of NI and the producer/consumer design pattern of LabVIEW for real-time acquisition and storage of the high-frequency data. Finally， the digital counting method is used to obtain the gear dynamic transmission error curve. The measuring speed of the testing system can reach 40 000 r/min， which is doubled the measurable speed of the previous test system， it can provide data support for vibration analysis and tooth surface design of higher-speed accessories transmission gear.
