Observing the Lubricant Regime of Spur Gears with Acoustic Emissions Technology

摘要

The application of high frequency Acoustic Emission (AE) as a condition monitoring tool to monitor gear condition is still under development, and as such, understanding the main source of AE during gear mesh and the influence of gear operating parameters on the generation of AE activity are essential. This paper presents experimental findings on the influence of specific film thickness (λ) under varying speed and load conditions on the generation of AE activity for operating spur gears. It was concluded that AE could be employed for monitoring specific film thickness (λ) on operational spur gears.
