20.500.12556/RUL-181203 Konstrukcija previsne žage za les Construction of an overhanging saw for wood Na domači kmetiji za ogrevanje koristimo lesno biomaso. V največji meri je to les iz domačih gozdov, ki ga želimo pripraviti na varnejši način. Ena izmed faz priprave lesa je razrez metrskih polen na krajšo dolžino. V zaključnem delu smo konstruirali previsno žago za razrez metrskih polen, primerno za manjši traktor. Analizirali smo obstoječe rešitve na trgu ter izvedli pregled patentov. Na podlagi izdelane morfološke matrike smo se lotili konstruiranja najbolje ocenjenega koncepta. Izračunali smo rezalno silo in določili ustrezen prenos moči. Konstrukcijo stroja smo razdelili na tri podsklope. Podrobneje smo preučili delovanje vseh elementov, ki so sestavni del podsklopa, imenovanega korito. Konstruirali smo 3D model stroja. V zadnjem delu smo izdelali stroškovno analizo in pripravili osnovno dokumentacijo. On our home farm, we use wood biomass for heating. To a large extent, this is wood from our own forests, which we want to prepare in a safer way. One of the stages of wood preparation is cutting meter-long logs into shorter lengths. In this thesis, an overhanging saw was designed for cutting meter-long logs, suitable for a smaller tractor. Existing solutions on the market were analysed and patents were reviewed. Based on the morphological matrix the best-rated concept was selected. The cutting force was calculated and the most appropriate power transmission was determined. The machine design was divided into three sub-assemblies. The operation of all elements that are an integral part of the sub-assembly were examined in detail 3D model of the machine was built. Finally, a cost analysis was performed and basic documentation was prepared. previsna žaga rezalna sila klinasti jermen ogrodje držalo polena korito vzmet overhanging saw cutting force V-belt frame log holder trough spring true false false [M.
