Abstract

In order to better understand the "black line" fault on the tooth surface of the gear pair, this paper collects about ten months of operating data of the faulty gear pair, analyses its vibration acceleration signal, obtains the modulation characteristics of the meshing frequency and the rotation frequency of the faulty gear from the time domain diagram and spectrum diagram, is able to find the gear tooth surface fault, and verifies the "black line" fault in the gear box endoscope, this characteristic can identify the tooth surface "black line" fault to some extent.
