Production of spare (substitute) parts for agricultural machinery

Ovim radom su obuhvaćeni najčešći primjeri i problemi trošenja, održavanja te maloserijske proizvodnje strojni dijelova za poljoprivrednu mehanizaciju te asortiman alata, naprava, radnog pribora i alatni strojeva kojima se služi tvrtka Tokarski obrt „Vojnović“ čiji je radni opseg najčešće u domeni poljoprivrednog sektora u širem području Slavonije. Predstavljeni su najdominantniji mehanizmi trošenja te je uz njih naglasak stavljen i na trošenje zemljom. Prikazani su cjelokupni tehnološki postupci potrebni za izradu pogonskog lančanika kao vitalnog strojnog elementa poljoprivrednog radnog stroja- freze . Za svaki tehnološki postupak i njegove zahvate provedena je analiza tehnološki zahtjeva, odabran je materijal, slikovito i tekstualno opisani su načini stezanja, te su prikazani i opisani alatni strojevi na kojima je reprezentativni proizvod izrađen. Utvrđena je važnost stručnosti praćenja te održavanja lančanog prijenosa snage i gibanja.This final work covers the most common examples and problems of wear, maintenance and small series production of machine parts for agricultural machinery and assortment of tools, devices, work accessories and machine tools used by the company Tokarski obrt „Vojnović“ whose scope is most often in the domain of the agricultural sector are in the wider area of Slavonia. The most dominant wear mechanisms are presented, and emphasis is placed on land spending. The entire technological procedures required for the production of a drive sprocket as a vital machine element of an agricultural mulcher are presented. For each technological procedure and its interventions, the analysis of technological requirements was performed, the material was selected, the methods of clamping were described pictorially and textually, and the machine tools on which the representative product was made were shown and described. The importance of monitoring expertise and maintaining chain transmission and motion has been determine
