Drive shaft fracture analysis

U sklopu ovog diplomskog rada provedena je analiza oštećenja pogonskog vratila. U teorijskom dijelu rada detaljno je opisan postupak provođenja analize uzroka oštećenja i lomova strojnih dijelova u eksploataciji. Navedena su zahtjevi i uvjeti za tehničke materijale koji se koriste za izradu pogonskih vratila za generatore velikih snaga. U sklopu eksperimentalnog dijela rada, provedena je temeljita vizualna kontrola cijeloga vratila te fraktografska i metalografska analiza. Na temelju dobivenih rezultata mjerenja i zapažanja tijekom analize donešeni su zaključci o potencijalnom uzroku loma, te predložene adekvatne preventivne mjere.As part of this thesis, a drive shaft failure analysis was performed. The theoretical part of the paper describes in detail the procedure for conducting an analysis of the causes of damage and fractures of machine parts in operation. The requirements and conditions for technical materials used for the construction of drive shafts for high power generators are listed. As part of the experimental part of this thesis, a thorough visual inspection, as well as fractographic and metallographic analysis was carried out. Based on the obtained measurement results and observations during the analysis, conclusions were made about the potential cause of fracture and adequate preventive measures
