A crack in the tooth root, which often results in failure of gear unit operation, is the least desirable among damages and faults, which can cause problems in gear unit operation. A fatigue crack in the tooth root brings about important changes in tooth stiffness, whereas other faults are ...
The impacts that a crack in a single-stage gear unit has on vibrations are dealt with. A fatigue crack in the tooth root brings about significant changes in tooth stiffness. Changes of other dynamic parameters are more associated with other faults. To analyze a non-stationary signal, time ...
By this procedure it is possible to evaluate the severity of impacts occurring between the teeth of unloaded gears, by examining the root mean square value of the signal. The Hilbert transform is largely adopted in the detection of gear defects, such as tooth cracks, but it has not yet ...
