Rolling bearing outer ring fault frequency: BPFOr ≌ 0.
4: the roller bearing inner ring failure frequency: BPFIr ≌ 0.
6 nn rolling bearing cage failure frequency: FTFr ≌ 0.
More than 4 n symbols: n = number of rolling elements.
N = shaft speed.
Note: 1.
Rolling bearing is no sliding;
2.
Rolling bearing geometry size no change;
3.
Fixed not rotating bearing outer ring.
