Vibration Spectral Characteristics of Distributed Gear Fault of Planetary Gearboxes
摘要
Abstract
A thorough understanding of the vibration signal spectral structure is helpful for fault diagnosis of planetary gearboxes via common yet effective spectral analysis. Considering both the amplitude modulation and the frequency modulation effects due to gear manufacturing errors or distributed faults, as well as the amplitude modulation caused by the passing effect of planets, signal models of normal and distributed fault cases and their Fourier transforms were given, and the spectral characteristics were summarized in closed form. Meanwhile, explicit equations for calculating the characteristic frequency of distributed gear fault were deduced. The theoretical derivations were validated using experimental datasets. According to the theoretical derivations, the naturally developed gear fault in a planetary gearbox was detected and located.关键词
