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.
Claims16
A method comprising:
- 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.
1 more element
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:
- 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,
- generate a profile of the impact energy signal, and
- declare a fault associated with an identified tooth included in the plurality of teeth based on an analysis of the profile.
