20.500.12556/DKUM-97017 Dynamic model of spur gear with friction and crack in tooth root A mathematical model developed to support investigation of pairs of gears is presented. It includes the effects of actuation, the loads, the changing tooth stiffness, and the changing friction between tooth flanks during engagement. Friction between the tooth flanks generates an alternating non-symmetrical periodic function and the behaviour during the contact. The system actuation is modelled for different sources and the tooth stiffness. The mathematical model of the mechanical system of gear has the form of a system of two non-homogeneous nonlinear second-order differential equations. dynamic analysis gear fatigue crack gears surface friction dinamična analiza razpoka zaradi utrujenosti zobnika zobniki površinsko trenje true false true HRČAK Angleški jezik Slovenski jezik https://hrcak.srce.hr/335278 Članek v reviji 2026-02-11 15:12:10 2026-02-11 15:12:11 2026-02-12 03:14:21 0000-00-00 00:00:00 2025 0 0 str. 642-646 no. 4, [article no.] 335278 Vol. 19 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-05-17 2024-02-22 2025-12-15 539.4 267658243 10.31803/tg-20240517182356 1848-5588 tj_19_2025_4_642-646.pdf tj_19_2025_4_642-646.pdf 1 8E6A9193106E35578A125CE847F1ED4F f249d5ed1d879d9c5f4b997e99252e52d22947ae34a80fb0b9e911602043cdb0 32868c74-0754-11f1-b759-00155d00019a https://dk.um.si/Dokument.php?lang=slv&id=203233 https://hrcak.srce.hr/335278 0 386e42c2-0754-11f1-b759-00155d00019a https://dk.um.si/Dokument.php?lang=slv&id=203234 Fakulteta za strojništvo 0 0 0
