Abstract (Croatian)

U ovom radu biti će opisani uvjeti proračuna te sam proračun radijalnog kliznog ležaja s hidrodinamičkim podmazivanjem pomoću norme ISO 7902. U teorijskom dijelu rada bit će opisana teorijska pozadina proračuna sa svim pretpostavkama i uvjetima koji su relevantni za proračun. U radu su također provedena dva proračuna kliznih ležaja. Prvi prikazani proračun razrađen je iz norme te opisuje odvođenje topline nastale u ležaju pomoću protoka ulja kroz ležaj. Drugi proračun opisuje odvođenje topline konvekcijom. Oba proračuna bit će provedena po dijelu norme ISO 7902-1. Na kraju rada priložen je crtež modela kliznog ležaja koji bi odgovarao kliznom ležaju proračunatom na odvođenje topline konvekcijom.

Abstract

In this paper assumptions and preconditions as well as calculation procedure of hydrodynamic plain journal bearing will be carried out according to ISO 7902 standard. In theoretical part of this paper, theoretical background of calculation procedure with all preconditions that are relevant for calculation itself will be discribed. Also, two calculations of hydrodinamic plain journal bearing are provided in this paper. First of them describes heat dissipation via the lubricant and second calculation describes heat dissipation by convection. Both of the calculation procedures will be carried out according to ISO 7902-1. At the end, model of the plain journal bearing that corresponds with the calculation based on heat dissipation by convection is provided in form of techical drawing.
