基于自混合干涉的齿轮箱故障诊断技术

摘要/Abstract

摘要：

将激光自混合干涉（SMI）技术用于齿轮箱的故障检测，设计出一种新的齿轮箱故障检测传感器。采用QL65D5SA型半导体激光自混合传感器、冯哈勃2342l012CR空心杯减速电机自带的行星齿轮箱，搭建了行星齿轮箱故障SMI检测系统，并对行星轮Z1做断齿故障实验。通过对时域波形的分析，可以找到额定转频下的12个冲击点；通过对齿轮箱故障信号傅里叶频谱的分析，发现故障齿轮的啮合频率周围出现与故障齿轮特征频率和行星架转频呈整数倍关系的边带，且啮合频率处的波形幅值明显增大，这些都与齿轮副的理论振动模型相符合。

Abstract:

Through the applications of laser SMI in the detection of gearbox, a new fault detection sensor for gearbox was proposed herein. A planetary gearbox fault SMI detection system was built by semiconductor laser self-mixing sensor QL65D5SA and planetary gearbox of hollow cup motor Faulhaber 2342l012CR. And the system was applied to do the wheel breaking tooth fault experiments for the planet Z1. Through the analyses of the time-domain waveform, 12 shock points were found at the rated frequency. Through the analyses of the Fourier spectrum of gearbox fault signals, it can be found that there are sidebands around the meshing frequency of the fault gear, which is an integer multiple of the characteristic frequency of the fault gear and the planetary frame transfer frequency. Amplitude of the wave at the meshing frequency is obviously increased, which is in accordance with the theoretical vibration model of gear pair.

Key words: self-mixing interference(SMI), fault detection, sensor, gearbox, shock point, Fourier spectrum, sideband
