Abstract
Izum motora s unutarnjim izgaranjem u devetnaestom stoljeću predstavljao je veliki napredak u području tehnike. Od tada pa do danas gotovo da nema područja u kojem motori s unutarnjim izgaranjem nisu zastupljeni bilo da se radi o benzinskom ili dizelskom motoru. Proizvodnja poljoprivrednih strojeva omogućila je ljudima lakše, jednostavnije, brže, ali i ekonomičnije obavljanje poslova obrade zemlje. S obzirom na težinu uvjeta rada, od strane proizvođača propisan je vijek trajanja za vitalne dijelove motora i transmisije, odnosno broj sati pri kojima se mora napraviti njihov remont ili zamjena. Ispitivanja u radu napravljena su na istrošenim dijelovima traktora, odnosno napravljena je analiza istrošenosti i mikrostrukture cilindarske košuljice, klipa i zupčanika reduktora. Cilindarska košuljica i klip zamijenjeni su pri generalnom remontu motora zbog istrošenosti, a zupčanik reduktora oštećen je uslijed umora materijala i preopterećenja. Na uzorcima dijelova analizirana je mikrostruktura na svjetlosnom mikroskopu i primjenom XRF-metode dobiven je kemijski sastav materijala od kojeg su dijelovi izrađeni. Cilj rada je prepoznati mehanizme trošenja analizirajući tragove trošenja na dijelovima, koji su uzroci njihovog nastanka te koje mjere se mogu poduzeti za smanjenje njihovog intenziteta.
Abstract (english)
The invention of the internal combustion engine in 19th century was a major improvement in the field of engineering. From then on, there are almost no areas in which internal combustion engines are not represented, whether gasoline or diesel engines. The production of agricultural machinery made it easier, simpler, faster and more economical for people to carry out land processing activities. Given the weight of operating conditions, the manufacturer prescribes the life span for the vital parts of engine and transmission, that is, the number of hours during which their overhaul or replacement must be made. The work tests were carried out on worn out parts of the tractor, that is, an analysis of wear and microstructure of the cylinder liner, piston and transmission gear was made. The cylinder liner and the piston were replaced during the general engine overhaul due to wear and the transmission gear was damaged due to fatigue of materials and overload. The microstructure of parts sample was analyzed on the light microscope and the chemical composition of the material from which the parts were made was obtained using XRF-method. The aim of this paper is to recognize the mechanisms of wear by analyzing the traces of wear on parts, which are the causes of their formation and which measures can be taken to reduce their intensity.
