20.500.12556/DKUM-25764 Method for detecting fatigue crack in gears The most undesirable damage that can occur in gear units is crack in the tooth root as it often makes gear unit operation impossible. Monitoring vibrations can be used to detect defects. Time signals are acquired experimentally and afterwards. Different methods can be used to analyse them. The changes in tooth stiffness caused by a fatigue crack in the tooth root are of significance. The dynamic response of a gear unit with a damaged tooth differs from the one of an undamaged tooth. Amplitudes of time signal are, by time-frequency analysis, presented as a function of frequencies in spectrum. gear drives fatigue failures crack initiation crack propagation vibrations zobniška gonila dimenzioniranje na življensko dobo utrujenostne poškodbe iniciranje mikrorazpoke širjenje razpoke poškodbe strojnih elementov vibracije true false false Angleški jezik Angleški jezik Neznano 2012-05-31 10:44:34 2012-05-31 10:44:34 2022-04-15 03:40:06 2023-12-31 03:23:07 2006 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.833:534.64 10714390 0167-8442 URN:SI:UM:DK:FHNUHNXB http://dx.doi.org/10.1016/j.tafmec.2006.07.002 1 https://dk.um.si/Dokument.php?lang=slv&id=34637 Fakulteta za strojništvo 0 0 0
