WebAug 12, 2016 · This testing uses a back-to-back gear test rig with a tooth profile designed to show micropitting relatively quickly and involves two test phases. The first phase is a sequential load stage test where the gears are inspected after each load stage for evidence of micropitting. Failure is defined as profile deviation greater than 7.5 µm. WebDec 15, 2024 · 3.1.4 Scuffing. Scuffing is not fatigue damage and is not capable of a fatigue life calculation. Scuffing is an instantaneous welding of the mating surfaces due to a collapse of the separating lubricant. Caused by the relative movement, the tooth flanks get disconnected from each other again instantaneously.
