20.500.12556/DKUM-89803 Rekonstrukcija reduktorja za napredovalni stroj GPK-PV diplomsko delo Reconstruction of the gearbox for the road head machine GPK-PV V diplomskem delu se bomo ukvarjali z izdelavo ohišja za reduktor napredovalnega stroja GPK-PV, ki je zelo pomemben stroj za podjetje Premogovnik Velenje d.o.o. Stroj je podjetje dolga leta razvijalo in je tako certificiran ter razvit v Sloveniji. Jekleni odlitki napredovalnega stroja GPK-PV so se do sedaj proizvajali v Rusiji, zaradi ruske invazije na Ukrajino pa je EU uvedla embargo na ruske izdelke. Trenutno imajo v podjetju težave z dobavo rezervnih odlitkov; zaustavitve proizvodnje zaradi dobave rezervnih delov si ne morejo privoščiti. V diplomskem delu se bomo ukvarjali z razvojem ohišja za napredovalni stroj GPK-PV. Pri tem bomo uporabili različne metode dela. Za analiziranje začetnega stanja smo uporabili metodo analize. Ko smo končali z analiziranjem obstoječega stanja, smo se lotili modeliranja, (metoda modeliranja). Na osnovi funkcionalne analize komponent in celotnega sestava bo določeno, katere komponente niso potrebne za zagotavljanje končne funkcionalnosti stroja. Le-te bodo odstranjene. Rezultat diplomskega dela je funkcionalno zmodelirano ohišje napredovalnega stroja, ki ga podjetje, če bo to potrebovalo, lahko da v izdelavo. V diplomskem delu smo tako naredili 3D model, izdelali preračune zvarov, naredili tehniško dokumentacijo in ekonomsko primerjavo in tehnično med starim ter novim izdelkom. In this thesis, we will focus on the production of the housing for the GPK-PV road head meachine gearbox, which is a very important machine for the company Premogovnik Velenje d.o.o. The company has been developing this machine for many years, and it has been certified and developed in Slovenia. Until now, the steel castings for the GPK-PV progressive machine were produced in Russia. However, due to the Russian invasion on Ukraine, the EU has imposed an embargo on Russian products. As a result, the company is now facing difficulties in obtaining replacement castings, and they cannot afford production stoppages due to the supply of spare parts. Therefore, in this thesis, we will focus on developing the housing for the GPK-PV progressive machine. We will use various methods for this work. To analyze the initial state, we employed the method of analysis. After completing the analysis of the existing state, we proceeded to modeling, using the modeling method. Based on the functional analysis of the components and the entire assembly, we will determine which components are unnecessary for ensuring the final functionality of the machine. These will be removed. The result of the thesis is a functionally modeled housing for the progressive machine, which the company can manufacture if needed. In the thesis, we created a 3D model, performed weld calculations, produced technical documentation, and conducted an economic and tehnical comparison between the old and new product. premogovništvo napredovalni stroj modeliranje GPK-PV reduktor rekonstrukcija coal mining road head meachine modeling GPK-PV gearbox reconstruction true true false J.
