| 摘要 | Embodiments are directed to obtaining an impact energy signal associated with each of a plurality of teeth of a gear over a revolution of a shaft associated with the gear, generating, by a computing device comprising a processor, a profile of the impact energy signal, and declaring a fault associated with an identified tooth included in the plurality of teeth based on an analysis of the profile. | ||

| 主权项 | 1. A method comprising: generating an estimated impact energy signal corresponding to each of a plurality of teeth of a gear over a revolution of a shaft associated with the gear tooth; obtaining an impact energy signal associated with each of the plurality of teeth; comparing the estimated impact energy signal with the obtained impact energy signal; generating, by a computing device comprising a processor, a profile of the impact energy signal; and declaring a fault associated with at least one tooth of the plurality of teeth, the fault being based on said comparing indicating a deviation between the estimated impact energy signal and the obtained impact energy signal in an amount greater than a threshold. | ||
