20.500.12556/DKUM-77865 Konstruiranje gozdarskega vitla s konstantno vlečno silo magistrsko delo Construction of logging winch with constant pulling force V delu je obravnavan problem padca vlečne sile na gozdarskem vitlu. Ta se zgodi z naraščanjem števila plasti žične vrvi na shranjevalnem bobnu. Zato je cilj naloge skonstruirati sistem, ki bo omogočil konstantno vlečno silo po vseh plasteh. Najprej je v fazi koncipiranja opisanih več konceptov. Sledi faza snovanja, v kateri se izdela računalniški model izbranega koncepta in predstavi rezultat konstruiranja. V sklopu analitičnih izračunov so prikazane glavne karakteristike vitla, vrednosti padca sile po plasteh in potrebni tlak v cilindru sklopke, da se dobi konstantna vlečna sila. Na koncu je z računalniškimi simulacijami preverjeno, ali so najbolj obremenjene komponente skonstruiranega sistema ustrezno dimenzionirane. This work deals with the problem of pulling force drop in forestry winch. This happens as the number of layers of wire rope on the storage drum increases. Therefore, the goal of the work is to construct a system that will enable a constant pulling force across all layers. First, several concepts are described in the conception phase. This is followed by a construction phase in which a computer model of the selected concept is created and the results of constructing presented. As part of the analytical calculations, the main characteristics of the winch, the values of force drop across the layers and the required pressure in the clutch cylinder to maintain a constant pulling force are shown. Lastly, with the help of computer simulatins is checked if the most loaded components of the designed system are correctly dimensioned. konstruiranje gozdarski vitel moment konstantna vlečna sila design forest winch moment constant pull force true true false [T.
