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.

Abstract
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.

8. An apparatus comprising:
-
at least one processor; and memory having instructions stored thereon that, when executed by the at least one processor, cause the apparatus to; generate an estimated impact energy signal corresponding to each tooth of the plurality of teeth; obtain 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; compare the estimated impact energy signal with the obtained impact energy signal; generate a profile of the impact energy signal; and declare a fault associated with at least one of the plurality of teeth, the fault being based on the comparison indicating a deviation between the estimated impact energy signal and the obtained impact energy signal in an amount greater than a threshold. - View Dependent Claims (9, 10, 11, 12, 13, 14)
