Two rotors are connected by the toothed wheel coupling with elastic plate packets. There are thin layers of oil between the plates and the semi-couplingsć teeth. Elastic contacts can occur between the plates, the plate packets and the semi-couplings' teeth. A dynamic model of the rotating system with the toothed-wheel coupling was designed and simulated. The simulation and experimental measurement results of the rotating system were used to identify the vibration sources and the failures of the elastic plates due to fretting corrosion and the misalignment of the rotorsPrispevek s pomočjo teoretičnega modeliranja in simuliranja obravnava dinamiko vrtilnega sistema turbine, skupaj s spremljanjem eksperimentalnih pogojev in diagnosticiranjem rezultatov. Dva rotoja sta povezana z zobniško sklopko s svežnji prožnih plošč. Med ploščami in polvprijemajočimi zobmi so tanke plasti olja. Med ploščami, ploščnimi svežnji in polvprijemajočimi zobmi lahko nastane prozni stik. Dinamični model vrtilnega sistema z zobniškim sklopom smo oblikovali in simulirali. Simulacijske in preizkusne merilne rezultate vrtilnega sistema smo uporabili za razpoznavo vira nihanj ter napak na prožnih ploščah, ki nastanajo zaradi korozijske obrabe in neporavnanosti rotorjevTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
