Abstract

Cilj ovog završnog rada je detaljnije istražiti utjecaj podmazivanja na trenje kliznih ležajeva
vojne tehnike. U uvodnom dijelu čitaoci su upoznati sa značajem pravilnog podmazivanja koje
prvobitno doprinosi produljenju životnog vijeka opreme vojne tehnike te potpomaže u
eksploataciji te iste. Kako bi znali koju vrstu maziva koristiti prvo se mora prepoznati vrsta
trošenja uzrokovana nekim trenjem, te stoga je prvi dio završnog rada posvećen vrstama i
uzrocima trenja. Drugi dio opisuje posljedice koje nastaju uslijed trenja, dakle trošenja, koja su
najviše povezana sa kliznim ležajevima na kojima je stavljen akcent u ovom radu. Nadalje se
spominju moderne vrste maziva izrađene po ISO 9001 programu kvalitete,te slijedi teorija
podmazivanja u kojoj se prepoznaju određene vrste i njihova korisnost. U finalnom dijelu se
nalaze konkretni primjer trošenja kliznih ležajeva kao i šteta uzrokovana puknućem kugličnog
ležaja u motoru samohodne haubice 122 mm 2S1 „Gvozdika“ poslije čega slijedi ispitivanje
trenja uz prisutnost maziva što zaokružuje ovaj rad.

Abstract (english)

The aim of this final thesis is to further explore the impact of lubrication on the friction of sliding
bearings in military equipment. In the introductory section, readers are introduced to the
importance of proper lubrication, which initially contributes to the extended lifespan of military
equipment and supports its operation. To determine the type of lubricant to be used, the first part
of the thesis focuses on identifying the types and causes of friction. The second part describes the
consequences of friction, particularly related to sliding bearings, which are the main focus of this
study. Furthermore, modern types of lubricants manufactured under the ISO 9001 quality
program are mentioned, followed by a discussion of lubrication theory that recognizes specific
types of lubricants and their utility. The final part presents specific examples of wear in sliding
bearings and the damage caused by the fracture of a ball bearing in the 122 mm self-propelled
howitzer engine, known as the 2S1 "Gvozdika." This is followed by an examination of friction in
the presence of lubricants, effectively concluding this study.
