摘要：
Planetary gearboxes starting, stoping and their load changes may cause variations of their rotational speed and their vibration signals with obvious non-stationarity. The vibration signals of a planetary gearbox are complex due to the complexity of its structure. The non-stationary vibration signals and their complex characteristics bring tremendous difficulties for a planetary gear box's fault diagnosis. Here, the order tracking method was introduced into the planetary sun gear fault detection under speed variation conditions, the fault characteristic orders of a speed-varying planetary gearbox were summarized. Comparing the traditional frequency domain methods with the order tracking method was made experimentally. The results showed that the order tracking method is effective for fault diagnosis of a planetary gearbox under speed-varying conditions. © 2016, Editorial Office of Journal of Vibration and Shock.
