Abstract

U teorijskom dijelu rada opisane su konstrukcijske karakteristike igličastih ležaja, postupci nitriranja te metode ispitivanja vibracije, buke i zagrijavanja ležaja. U eksperimentalnom dijelu rada provedena su nitriranja u plazmi, solnoj kupci TENIFER i plinskoj atmosferi amonijaka na prstenima igličastog ležaja od čelika 100Cr6. Na nitriranim prstenima provedena su mjerenja hrapavosti površine i odstupanja od kružnosti te dinamička ispitivanja vibracija, buke i zagijavanja igličastog ležaja sastavljenog od nenitriranog vanjskog prstena s iglicama i nitriranog unutrašnjeg prstenana brzinama vrtenje 510 o/min, 725 o/min i 1500 o/min. Na temelju provednih ispitivanja najbolja ležajna svojstsva pokazali su unutrašnji prsten nitrokarburiran postupkom TENIFER i prsten nitriran u plazmi s parametrima 450 C/6h.

Abstract (english)

In the theoretical part of the work, the structural characteristics of needle bearings, nitridin procedures, and methods of testing vibration, noise and bearing heating are described. In the experimental part of the work, nitridin was carried out in plasma, TENIFER salt and ammonia gas atmosphere on the rings of the needle bearing made of steele 100Cr6. On the nitrided rings, measurements of surface roughness and deviation from circularity were carried out, as well as dynamic tests of vibrations, noise and wear of needle bearing composed of a non-nitrided outer ring with needles and a nitrided inner ring at rotation speeds of 510 rpm, 725 rpm and 1500 rpm. Based on tests carried out, the inner ring nitrocarburized by the TENIFER process and the ring nitrided in plasma with parameters 450 ºC/6h showed the best bearing properties.
