The vibration signals used in this dataset were collected from 1.5 MW wind turbines in June 2020. The wind farm locates in eastern China. The planetary gearbox contains two-stage planetary and one-stage parallel transmission mechanisms. Vibration signals were acquired using a piezoelectric accelerometer (VIB 6.140) mounted on the ring of the second-stage planetary mechanism of the gearbox by a DAQ system with a sampling frequency of 16384 Hz.
