Table 2 Gear status at different monitoring times.
From: Time-weighted kernel density for gearbox residual life prediction
Monitoring time | RMS curve | Monitoring gear status |
|---|---|---|
\(t \in \left[ {0,10} \right]{\text{h}}\) | Showing a gradual decrease | Initial meshing stage |
\(t \in \left[ {10,68} \right]{\text{h}}\) | Showing a gradual increase | Normal fatigue wear stage |
\(t \in \left[ {68,77} \right]{\text{h}}\) | Starting to increase sharply | Fatigue and wear increase until the tooth is broken |
