Abstract
V magistrskem delu je predstavljen proces konstruiranja novega gumijastega gnetilnika za diskaste kosilnice. Opisani so način in namen uporabe gnetilnikov, njihove prednosti in slabosti. Prikazane so trenutne izvedbe gumijastih gnetilnikov z dvema valjema. Izvedena je raziskava trga na področju diskastih kosilnic. Ugotovljene so bile priložnosti za nove rešitve. Opisane so ideje za izboljšave oz. nove rešitve postavitve valjev. Predstavljeni in vrednoteni so koncepti za novo izvedbo gumijastega gnetilnika. Za izbrani koncept (trije valji, gnani z zobniškim gonilom) je opravljeno detajliranje in modeliranje komponent. Prikazan je potek moči od traktorja do grebena in gumijastega gnetilnika. Opisani so proces izračuna oz. določitve geometrije zobnikov (stožčastih in valjastih), preračun medosnih razdalj, dimenzij gredi, izbira ležajev in oblikovanje ohišja. Natančneje je opisana, detajlirana in vrednotena stožčasta zobniška dvojica po standardu SIST ISO 10300. Izvedeno je vrednotenje gredi v gonilu in prikazana celotna zasnova gonila. Cilj znotraj magistrskega dela je bil razviti novo gonilo, ki bo nato izdelano, testirano in v prihodnosti implementirano na kosilnicah z gumijastim gnetilnikom.

Title:Construction of gear box for roller conditioner for disc mowers
Abstract:
This thesis describes the process of construction and development of the new roller conditioner for disc mowers. It describes the types and usage of conditioners for disc mowers. The current solutions of roller conditioners with two rollers are shown and described, the thesis also contains analysis of the market and shows new opportunities for upgrades. The ideas for better positioning of rollers are described. Furthermore, new concepts are described and rated. The chosen concept (with three rollers and a gear box) is detailed and models are created. The process of power path from the tractor to the mower is described. This thesis includes the calculation of geometry for spur and bevel gears, calculations of distances between axes, shafts dimensions, construction of housings and bearings. The complete calculation of bevel gears is conducted and described, according to standard SIST ISO 10300. The calculations of shafts and whole design of gear box are included. The goal of this thesis is to develop new gear box, which will be made, implemented and tested on the mowers with roller conditioners.

Keywords:disc mower, roller conditioner, gear box, lawn mowing, conditioning mow
