Vpliv strojnega brušenja verige motorne žage na učinkovitost prežagovanja lesa in tresenje rok : diplomsko delo - univerzitetni študij - 1. stopnja = The impact of machine chain sharpening on the efficiency of cross-cutting and exposure to vibrations : B. Sc. Thesis - Academic Study ProgrammesBrkopec, ŽanV diplomski nalogi smo raziskovali vpliv strojnega brušenja verige motorne žage na učinkovitost prežagovanja lesa in tresenje rok. V raziskavo smo vključili štiri verige proizvajalca STIHL modela ... 3/8'' 1,6 RAPID SUPER (RS), in sicer industrijsko nabrušeno verigo in tri verige, ki smo jih nabrusili s stroji za brušenje (Stihl USG, Tecomec Super Jolly, Vollmer Werke Cane/e). Z vsako verigo smo izvedli 18 prežagovanj smrekove prizme z motorno žago Stihl modela MS 362. Rezultati raziskave so pokazali, da je bilo prežagovanje z naknadno nabrušenimi verigami za 55 % do 81 % manj učinkovito kot z industrijsko nabrušeno verigo. Med strojno nabrušenimi verigami je bila najučinkovitejša veriga, nabrušena z najdražjim strojem Vollmer Werke Cane/e. Jakost tresenja na nosilnem in vodilnem ročaju je bila največja pri uporabi industrijsko nabrušene verige, najmanjša pa pri verigi, nabrušeni z najdražjim strojem Vollmer Werke Cane/e. Pri uporabi vseh verig je bila jakost tresenja večja na nosilnem kot na vodilnem ročaju. Vsebnost vode v lesu vpliva na učinkovitost prežagovanja kakor tudi na jakost tresenja motorne žage, kar pa velja samo za strojno brušene verige. Z učinkovitostjo prežagovanja se pri uporabi industrijsko nabrušene verige značilno povečuje jakost tresenja na obeh ročajih. Ugotovitve raziskave so uporabne za lažjo odločitev pri izbiri stroja za brušenje verige motorne žage za profesionalnega gozdarskega delavca ali za občasnega uporabnika motorne žage.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [Ž.
