摘要
用微型计算机和光栅传感器组成的仪器可在现场测量并分析各种传动比齿轮传动链的传动误差。仪器采用锁相倍频技术提高了测量精度,采用数字选频和细化谱分析方法增强了诊断误差来源的能力。
An instrument based on microcomputer and grating tensor can be used to test and analyse the gear-driven error of various ratio gear trains on the spot. Adopting the techniques of the PLL(phase-locked loop) multiple frequency, the test accuracy of the instrument is increased. Adopting the numerical frequency selection and fine frequency analysis, the instrument is able to diagnose exactly the error source.
