Dataset of bearing（time-frequency domain）

This is a dataset designed for the paper "Bearing Unbalance Fault Diagnosis Based on RFH-GAN and PSA-DRSN".

Test the bearing support motor shaft. Using electric discharge alone to introduce point faults into the test bearing, the diameter of the fault is 7 mils, 14 mils, 21 mils, 28 mils, and 40 mils for machining (1 mil=0.001 inch). SKEFL bearings are used for faults with diameters of 7, 14, and 21 mils, as well as NTN 28 mil and 40 mil faults using equivalent bearings. The specifications of the drive end and fan end bearings, including bearing geometry and defect frequency, are listed in the bearing specifications.
