Deformacija zoba polimernega zobnika : zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni programNuhanović, NerminaV zaključni nalogi smo analizirali deformacijsko stanje zoba polimernega zobnika, ki je posledica sil v kontaktu gonilnega in gnanega zobnika. Zob zobnika obravnavamo kot konzolno vpeti nosilec, ki ... po svoji dolžini ima spremenljivo geometrijo. Silo v kontaktu, ki se s časom premika po boku zoba poenostavimo kot vertikalno silo, ki deluje na koncu nosilca. Deformacijo smo preračunali po EulerBernoullijevi in Timošenkovi teoriji nosilcev ter primerjali rezultate izračunov. Enačbe za opis spreminjanja lege nevtralne osi najprej izpeljemo ob predpostavki elastičnega nosilca s konstantnimi mehanskimi lastnostmi. S pomočjo definiranja temperaturnega polja zoba zobnika in določenih predpostavk smo v matematični model vključili pomembno lastnost polimernih materialov - odvisnost mehanskih lastnosti od povišane temperature, ki je posledica izgub zaradi viskoelastičnosti gradiva. Ovrednotimo količino generirane toplote v zobu in upogib nosilca s temperaturno odvisnimi mehanskimi lastnostmi primerjamo z upogibom nosilca s konstantnimi mehanskimi lastnostmi. S tem smo želeli pokazati ustreznost posameznih deformacijskih teorij v različnih okoliščinah in poudariti pomen upoštevanja vpliva temperature pri zagotavljanju zanesljivosti polimernih zobnikov.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [N.
