Description of the Working Principle of the Follower and Electromechanical Nailer of the M-84 Tank Cannon

Cilj ovog završnog rada je prikazati i opisati rad donosača i utvrđivača top na tenku M-84. Prije same obrade donosača i utvrđivača topa, spomenut je tenk M-84, opisani su automati punjenja na francuskom tenku Leclerc, američkom borbenom oklopnom vozilu M1128 Stryker MGS i jugoslavenskom tenku M-84. Opis ovih automata je informativnog tipa kako bi se pokazalo da ne postoji jedan način automatskog punjenja, nego da ima više načina ovisno o vozilu, zahtjevima, namjeni... Kroz rad obrađeni su donosač i utvrđivač topa, opisani su njihovi dijelovi i rad pojedinog dijela kao i cijelog sklopa, te su izrađeni 3-D modeli donosača i utvrđivača topa u programu SolidWorks. Zatim se opisuje cijeli proces punjenja na tenku M-84 u tri režima rada, a nakon toga se detaljnije objašnjava rad donosača i utvrđivača topa pri samom punjenju topa te je njihov rad prikazan slikama modela izrađenih u spomenutom programu. Pri kraju rada opisuju se neispravnosti donosača i utvrđivača topa, kako su nastale te neispravnosti te kako se otklanjaju, a na samom kraju prikazana je i ilustrirana mehanička deblokada topa. Ovakav pristup radu olakšava učenje o radu donosača i utvrđivača topa budućim generacijama kadeta.This thesis aims to provide a detailed analasys encompassing operating principles of the rammer as well as the gun elevation blocking mechanism on the main weapon of the M84 main battle tank. However before going any deeper on this subject, it is necessary to take a broader look on the design and development of contemporary automatic reloading systems, including those on the French Leclerc MBT, American M1128 Stryker MGS and on the Yugoslav M84 MBT. The description of this systems is given on purely informational basis, showing many different features and approaches, depending on the vehicle role and type. Throught this thesis the emphasis was on the rammer and the gun elevation blocking mechanism, with all of their details, parts and sub-systems modelled in 3D SolidWorks computer aided design software. Also thoroughly described is the reloading process on the M84 MBT across all of its three basic operating modes. Through this approach it is possible to provide a clearer picture on the roles of the rammer and the gun blocking mechanism in the system as a whole. This is enable through pictures and schematics of the 3D models generated in CAD. In conclusion some of the most common malfunctions of these parts are shown, with means by which these are mitigated. Mechanical gun de blocking is also shown. This approach greatly improves learning experience with the new generations of cadets
