Raziskava delovanja gonil z zmanjšano količino tekočih maziv : doktorsko deloKržan, BorisPovečevanje razmerja prenesene moči na enoto volumna je prepoznano kot eden izmed poglavitnih ciljev sodobnih zobniških gonil. Posledica zmanjševanja zunanjih dimenzij so večje kontaktne obremenitve ... in manj olja v sistemu, kar vodi do povišanih temperatur ter manjše debeline oljnega filma za ležaje in zobnike. V delu je izpostavljeno področje tehnologije zaščitnih prevlek na osnovi diamantu podobnega ogljika DLC. Na zobniškem preizkuševališču FZG smo izvedli preizkuse z zobniškimi dvojicami z in brez zaščitne prevleke. Preizkuse smo izvedli z zmanjšano količino olja v sistemu, zobnik je bil v oljno kopel potopljen za globino 3-kratne vrednosti modula. Zobniški par s prevleko W-DLC in posebej prilagojeno formulacijo olja je dosegla višjo nosilnost v primerjavi s standardno zobniško dvojico in konvencionalnim oljem za gonila podobne viskoznosti. Približno 40 % nižja srednja aritmetična hrapavost zobnih bokov s prevleko je vzrok za 2-krat višjo vrednost parametra oljnega filma , v primerjavi s standardno kombinacijo. Zobniki z zaščitno prevleko so med obratovanjem podvrženi stalni obrabi, kjer se na površini generirajo majhni delci, površini v kontaktu pa se zgladita. Gladka površina zobnih bokov je tudi vzrok za odpornost na poškodbo jamičenja, ki preseže izračunano mejo za gonilo s polno polnitvijo olja, kot tudi obratovalno dobo standardnih zobniških dvojic s cementirano površino.Type of material - dissertation ; adult, seriousPublication and manufacture - Ljubljana : [B.
