Analiza deformabilnosti zoba polimernega zobnika : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoMlinarič, Tilen, strojnikMnogo strojev na svetu vsebuje zobnike, ki so v veliki večini narejeni iz jekla. Dandanes se na trg široke potrošnje prebijajo zobniki iz polimernih materialov, ki pa imajo svoje prednosti in ... slabosti. Z zobniki prenašamo moment preko majhne stične ploskve med dvema zoboma. Pri prenašanju obremenitve pride do raznih pojavov, npr. elastične deformacije zoba, generacije toplote in spremembe geometrije. V kolikšni meri bo prišlo do pojavov, je močno odvisno od geometrije in materiala zobnika. Zanimalo nas je, do kakšnih deformacij pride in kakšna je razporeditev napetosti. Deformacijo smo preračunali po deformacijski teoriji, ki velja za malo deformirane nosilce. Eksperimente smo izvedli na dveh enakih zobnikih iz prosojnega polimernega materiala, ki nam je omogočil uporabo metode fotoelastičnosti. Zaradi relativno velikih upogibov in s tem povesa smo ugotovili, da teorija deformacij majhnih pomikov ni najboljša izbira. Za dobre meritve povesa je potrebno imeti ostro sliko in razločno viden rob, da se zmanjša doprinos napake zaradi subjektivne narave merjenja dolžine v programu. Porazdelitev napetosti po zobu nam da vpogled v najbolj obremenjena področja zoba in pokaže, da se pojavi največja napetost v stični točki.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [T.
