Obdelava in racionalnost novega profila koles pri železniških vozilih : diplomska naloga visokošolskega strokovnega študijaTepina, BorutObraba tekalne površine na obročih železniških koles je pojav, ki se mu ni moč izogniti. Z obrabo se istočasno spreminja profil tekalne ploskve, kar iz vidika varnosti prometa, glede na spremenjene ... pogoje teka in razporeditve obremenitev na kolo, zahteva struženje, da se ponovno doseže nov, predpisan profil. Mednarodna železniška zveza je zaradi racionalizacije stroškov predpisala nov profil koles, ki predvideva prihranek pri struženju. Za potrebe vzdrževanja je treba napraviti natančen izračun odvzema materiala pri novem profilu in dobljene rezultate zaradi boljše preglednosti zajeti v tabeli. Hkrati je treba izdelati tudi diagram odvzema, kjer je možnost odčitavanja posameznih vrednosti še bolj natančna. Pri vsem tem se mora upoštevati predpisane mejne mere koles in profilov v eksploataciji železniških vozil. Uvedba novega profila koles predvideva prihranek pri struženju oz. vzdrževanju, zato je treba napraviti natančen izračun stroškov, ki nastanejo pri tem, in jih primerjati s stroški struženja dosedanjega profila.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [B.
