Abstract
Iako su vrlo osjetljivi na nepravilnosti nastale u proizvodnji, zupčanici s velikim stupnjem prekrivanja profila (HCR, engl. high transverse contact ratio) u sve su češćoj upotrebi zbog povećane nosivosti u odnosu na zupčanike s niskim stupnjem prekrivanja profila. Procedura izračuna raspodjele sile na parove zuba u istodobnom zahvatu izvedena za HCR zupčanike s odstupanjem koraka na zahvatnoj crti bitno ovisi o položaju parova zuba u zahvatu s obzirom na vrijednosti odstupanja. Kritični položaj parova zuba u zahvatu koji izaziva najveći porast naprezanja u odnosu na naprezanja geometrijski točnih zupčanika, definiran je u ovom radu.High transverse contact ratio (HCR) gears are more frequently in use because of their increased load-carrying capacity compared to low contact ratio gears, although they are very sensitive to manufacturing errors. The calculation procedure of load distribution, established for HCR gears with pitch errors, depends on the position of tooth pairs, with regard to pitch error. The critical position of tooth pairs, which causes the maximum stress increase, compared to geometrically ideal gears, is defined in this paper
