Abstract
U teorijskom dijelu rada opisani su igličasti ležaji, njihove karakteristike, postupci nitriranja prstena ležaja te metode ispitivanja hrapavosti površine, mjerenje temperature i vibracija ležaja. U eksperimentalnom dijelu provedeno je nitriranje unutarnjeg prstena igličastog ležaja od čelika 100Cr6 u plazmi N2+H2 i nitrokarburiranje u solnoj kupci TENIFER. Provedeno je ispitivanje hrapavosti površina nenitriranog i nitriranih prstenova koje je pokazalo povećanje hrapavosti primjenom nitrokarburiranaj u solnoj kupci, dok nitriranje u plazmi nije značajnije utjecalo na hrapavost površine. Nenitrirani i nitrirani prstenovi izloženi su vrtnji u igličastom ležaju bez opterećenja, pri brzinama 950 min-1, 1025 min-1 i 1215 min-1 u trajanju od 1 min, bez podmazivanja. Tijekom rotacije igličastih ležaja provedena su mjerenja vibracija, buke i temperaturnog polja ležaja. Iz provedenih ispitivanja, može se zaključiti da unutarnji prsteni nitrirani u plazmi te prsteni nitrokarburirani postupkom TENIFER, imaju bolja svojstva nego prsten u polaznom stanju, odnosno manje se zagrijavaju, imaju manji nivo buke i amplitudu vibracija.
Abstract (english)
In the theoretical part of the work, needle bearings, their characteristics, nitriding procedures of the bearing rings and methods of testing the surface roughness, measuring the temperature and vibration of the bearing are described. In the experimental part, nitriding of the inner ring of the needle bearing made of 100Cr6 steel in N2+H2 plasma and nitrocarburizing in the TENIFER salt bath were carried out. The surface roughness of non-nitrided and nitrided rings was tested, which showed an increase in roughness with the use of nitrocarburized in salt water, while nitriding in plasma did not significantly affect the surface roughness. Non-nitrided and nitrided rings are exposed to rotation in a needle bearing without load, at speeds of 950 min-1, 1025 min-1 and 1215 min-1 for 1 min, without lubrication. During the rotation of the needle bearings, measurements of vibrations, noise and the temperature field of the bearing were carried out. From the conducted tests, it can be concluded that inner rings nitrided in plasma and rings nitrocarburized by the TENIFER process have better properties than the ring in its initial state, i.e. they heat up less, have a lower noise level and vibration amplitude.
