Maintenance of self-propelled howitzer transmission

U radu su opisani sklopovi hodnog dijela koji su bitni za funkcionalnost i pokretljivost samohodne haubice. Tijekom upotrebe samohodne haubice 122 mm može doći do pojave neispravnosti ili oštećenja dijelova i sklopova. Te neispravnosti često mogu biti uzrok težih oštećenja ako se na vrijeme ne uoče ili otklone. Da bi se to izbjeglo u radu su opisani modeli održavanja koji omogućuju pouzdan rad i ispravnost samohodne haubice. U radu su prema tehnološkom redoslijedu opisane radnje zamjene i popravke sklopova i dijelova. Prije opisivanja procesa zamjene sklopova navedeni su razlozi zbog kojih se izvršavaju opisani radovi. Na kraju rada napravljena je analiza trajanja održavanja transmisije. Analiza sadržava popis aktivnosti remonta hodnog dijela, ovisnost aktivnosti i trajanje aktivnosti te je izraĎen plan remonta u mrežnom i linijskom dijagramu.In the paper are describes parts of moving body that are essential for the functionality and mobility of self-propelled howitzer. During the use of self-propelled howitzer may occur malfunctions or damage of parts and assemblies. These malfunctions can often be the cause of more serious damage if they are not noticed on time or remove. To avoid this, the paper describes maintenance models that allow reliable work and correctness of self-propelled howitzer. In the paper according to technological order are described actions of replacement and repair of assemblies and parts. Before describing the process of replacing assemblies are given the reasons why these actions are being executed. At the end of this paper, an analysis of the transmissions maintenance duration was made. The analysis contains a list of activities of overhaul of moving body, activity dependence and duration of activity and plan has been made of overhaul in network and line diagram
