The application of high-frequency acoustic emission (AE) technology to condition
monitoring of gears is still in its infancy. Understanding the influence of gear
operating parameters on the generation of AE is essential in applying the AE
technology to gear condition monitoring. This paper presents experimental
findings on the influence of speed and load in generating AE for operating
helical and spur gears. The experimental findings suggest that any percentage
reduction in specific film thickness (gimel), a direct consequence of a change
in load condition, results in a nine- and four-fold percentage change in AE rms
for the spur and helical gear sets, respectively. A numerical model representing
changes in AE rms with variation in load and speed under near isothermal
conditions for spur and helical gears was also established. In conclusion, it is
postulated that the AE technology could offer a means of measuring in situ the
effectiveness of a lubricant for operational spur and helical gears thereby
establishing if the correct lubricating conditions are present to ensure optimal
life usage
