As a key component for carrying wind wheels and generators, gearboxes work under severe conditions of variable speed and load for a long time. The vibration signals generated by plum-shaped elastic couplings mostly contain Gaussian noise, and have non-stationary and non-linear characteristics. The faults that occurred include: gear damage, bearing damage, oil leakage, broken shaft, poor lubrication, shaft misalignment, shaft imbalance, high oil temperature, etc.
