A Novel Bearing Fault Diagnosis Method Based on Gaussian Restricted Boltzmann Machine

Figure 5

Time domain signals of some fault types under four different loads: (a) normal; (b) inner race fault (7 mil); (c) outer race fault (7 mil); (d) ball fault (7 mil); (e) inner race fault (14 mil); (f) outer race fault (14 mil); and (g) ball fault (14 mil). The colors blue, red, purple, and green represent the 0 hp, 1 hp, 2 hp, and 3 hp load, respectively.
