Analysis of Micro-Elastohydrodynamic Lubrication and Prediction of Surface Fatigue Damage in Micropitting Tests on Helical Gears

This collaborative work with Newcastle University has revealed detailed fatigue behaviour in helical gear micropitting tests and shows that surface finish alone does not explain differences between the micropitting performance of gears. It is clear from the paper that different gear manufacturing processes, in this case form-grinding and generator-grinding, can give significantly differing performance in practice. The work was supported by EPSRC /G06024X/1 £423k with industrial financial support from a British Gear Association Research Consortium, and Aero Engine Controls (Rolls Royce Group), and has led to new collaborative work (2013-16) with NASA Glenn Laboratory (Tim Krantz) under US Army sponsorship.
