根据齿面磨损、偏心和轴承的振动等会引起齿轮系统齿侧间隙时变这一特性,提出了基于动态侧隙的齿轮系统齿面磨损故障分析方法。综合考虑动态啮合刚度、动态齿侧间隙、摩擦、偏心等因素建立了单级齿轮传动系统六自由度啮合耦合型动力学模型,给出了全齿均匀磨损和偏心磨损故障的仿真方法,并对含故障齿轮系统动力学行为进行了分析。最后,利用齿轮实验台对齿侧间隙增大的磨损故障进行了模拟,验证了理论分析结果。研究表明,齿轮系统传递误差、振动冲击状态和振动剧烈程度等会随齿面磨损形式和程度不同而变化,为齿面磨损故障的监测与诊断提供了理论依据。

An analysis method based on dynamic backlash for a spur gear system with tooth-wear fault was proposed according to the characteristic of a time-varying backlash caused by tooth-wear,eccentricity and bearing vibration in a gear system.Moreover,a meshing coupled dynamic model with 6-DOF for a single-stage spur gear system was built considering time-dependent meshing stiffness,dynamic backlash,friction and eccentricity.The simulation methods were presented to analyze the dynamic behaviors of the gear system with uniform tooth-wear fault and eccentric tooth-wear fault.At last,the wear fault tests with increase in backlash were performed on a gear system experimental bench,the tests verified the theoretical analysis results.Study results showed that the gear system transmission error,shock status and vibration intensity vary with different forms and levels of wear fault,they provide a theoretical basis for monitoring and diagnosing tooth-wear faults of a gear system.
