A Preliminary Evaluation of Some Gear Diagnostics Using Vibration Analysis

Several conditions monitoring methods for gears, which use the signal average of gear vibrations in both the time and frequency domain, have been investigated during a 1500 hour test on a gear rig. Results have shown that although heavy wear, in the form of fine pitting and scuffing, occurred over m...

Description
Summary:Several conditions monitoring methods for gears, which use the signal average of gear vibrations in both the time and frequency domain, have been investigated during a 1500 hour test on a gear rig. Results have shown that although heavy wear, in the form of fine pitting and scuffing, occurred over most of the tooth surfaces, the time domain procedures and levels of the fundamental and first harmonic of meshing frequency did not respond to damage to the gears. Total vibration and the ratio of sideband to total energy showed only marginal response to wear. Keywords: Condition monitoring; Gears. (Australia)
