Abstract

The main gearbox is an important driving force for a pump. It needs to carry out regular monitoring. In this paper, it measures the vibration acceleration signal of a pumping unit’s main gearbox, names them 1# and 2#. After comparing the time course curve and spectral of the two main gearbox, it has found the 2# gearbox’s maximum amplitude is about 2.5 times than the 1#. The narrowband signals are filtered by Hilbert transform to obtain the envelope of the narrow band signal. The envelope signals are significant different between the two gear boxes, 1# gearbox has more spectrum of frequency, and 2# gearbox is more outstanding single frequency component. The results show that the presence of the 2#gearbox has some minor faults. The 2# gearbox is more wear than 1# gearbox, which explains the rationality of the vibration analysis.
