Priprava verige in njen vpliv na učinkovitost prežagovanja : diplomsko delo - visokošolski strokovni študij - 1. stopnja = Chain maintenance and its impacts on the performance of crosscutting with the chainsaw : B. Sc. Thesis - professional study programmesDužnik, MartinCilj in namen diplomskega dela je bil ugotoviti, kako priprava verige motorne žage, drevesna vrsta in tip verige vplivajo na učinke pri prežagovanju lesa ter strukturo in obliko žagovine. Les bukve ... in jelke se je predhodno prizmiralz vertikalno krožno žago na dimenzijo 32 cm x 32 cm, napake pa se je izločilo med samim poskusom. Za prežagovanje lesa se je uporabilo motorno žago Husqvarna 372 xp, 45 cm dolg meč Stihl z 1,6 mm utorom ter verige Oregon in Stihl, katere so bile nabrušene pod tremi različnimi koti ostrine rezilcev in tremi različnimi višinami globinskih zob. Rezultati so pokazali, da se učinki prežagovanja v splošnem povečujejo z zniževanjem kota ostrine in s povečevanjem višinske razlike med rezilci in globinskimi zobi. Prežagovanje je učinkovitejše pri uporabi verig Oregon ter pri obdelavi lesa jelke. Deleži ostružkov z velikostjo 0,063 mm so večji pri manj znižanem globinskem zobu in manjših kotih ostrine rezilcev ter pri bukvi in verigah Oregon. Na dolžino ostružkov značilno vpliva kot ostrine rezilcev in drevesna vrsta, na širino drevesna vrsta in tip verige, na njegovo debelino pa višina globinskega zoba, drevesna vrsta in tip verige. Ugotovitve raziskave so uporabne za povečevanje učinkovitosti kakor tudi varovanje zdravja pri poklicnem in nepoklicnem delu z motorno žago.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
