Gear is one of the most important mechanical elements in power

transmission.

It is used to transmit motion and/or torque mechanically b/w

parallel, intersecting or non-intersecting shafts

Power transmission using gears result in cyclic loading for the

individual gear tooth. Cyclic loading may leads to various gear

faults

Example of gear tooth faults Cont..

Vibration signals is most commonly used method in condition

monitoring.

Diagnosing a gear system by examining the vibration signals is

the most commonly used method for detecting gear failures.

Vibration signal encountered in machines and such as machine

tool and gear box can be classified as:

Stationary

Non-stationary
