Crack Growth Behaviour of Spur Gears: A Fractographic Analysis.

Abstract

Vibration Analysis offers a means of detecting faults in gear systems without the need for costly periodic overhaul and inspection, and promises substantial cost savings in several military platform applications. The correlation of vibration analyses with fatigue crack growth forms an essential part of ongoing research aimed at maximizing the information which can be obtained from vibration analyses. This report discusses the use of fractographic analysis to determine the growth behaviour of fatigue cracks in four case-hardened low-alloy steel spur gears.
