20.500.12556/DKUM-66531 Methods for detecting fatigue cracks in gears A crack in the tooth root is the least desirable damage caused to gear units and it often causes failure of gear unit operation. For fault analyses presented in this article, gear units with real damages or faults produced on the basis of numerical simulations of real operating conditions are used; tests were carried out in a laboratory test plant. Damages in gear units can be identified by monitoring vibrations. The influences of a crack in a single-stage gear unit on produced vibrations are presented. Significant changes in tooth stiffness are caused by a fatigue crack in the tooth root whereas, in relation to other faults, changes of other dynamic parameters are more expressed. Non-stationary signals are analysed, using the family of Time Frequency Analysis tools, which include Wavelets and Joint Time Frequency Analyses. gear unit vibrations tooth root time frequency analysis tool krmilna enota vibracije zobni koren orodje za analizo časovne frekvence true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-06-30 09:13:19 2017-06-30 09:14:23 2022-07-11 03:07:32 2019-07-11 15:50:35 2009 0 0 str. 1-7 Letn. 181 2009 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1742-6588 534:621.88 13424662 13424918 10.1088/1742-6596/181/1/012090 1742-6596 URN:SI:UM:DK:CX4VHIVV Journal_of_Physics_Conference_Series_2009_Belsak,_Flasker_Methods_for_detecting_fatigue_cracks_in_gears.pdf Journal_of_Physics_Conference_Series_2009_Belsak,_Flasker_Methods_for_detecting_fatigue_cracks_in_gears.pdf 1 D3FF65FD85C2A0346445205D89C438C5 ee1196d3ff10304f1a8bc687948cfdd0ea653f6e3c4c4a2167c424fb909b3917 537c8346-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=113375 http://stacks.iop.org/1742-6596/181/i=1/a=012090?key=crossref.a95d505b9eaa7e6711672d125ab22f98 1 https://dk.um.si/Dokument.php?lang=slv&id=113374 Fakulteta za strojništvo 0 0 0
