Acoustic emission and specific film thickness (lambda) for spur gears

This technical note presents experimental evidence of the correlation between AE activity and the specific film thickness (A) for operational spur gears. The film thickness was varied during operation by spraying liquid nitrogen on to the rotating gear wheel. Observations showed that at a lambda (A)...
