Abstract. In this paper the effect of the teeth geometry and the load distribution at simultaneously meshed teeth pairs to stress in the tooth root is analyzed, when within the contact period the single and double and double and triple mesh follow each other. On the basis of analytical researches the exact and the approximate mathematical models are formed for determining the operating and critical stress at the tooth root relevant for checking the gear tooth volume strenght are created.

RAZVOJ TEORIJSKOG MODELA ZA ODREĐIVANJE NAPONA MERODAVNOG ZA PROVERU ZAPREMINSKE ČVRSTOĆE ZUPCA ZUPČANIKA U radu je analiziran uticaj geometrije zubaca i raspodele opterećenja kod istovremeno spregnutih pari zubaca na napon u podnožju zupca, kada se u toku dodirnog perioda smenjuju jednostruka i dvostruka i dvostruka i trostruka sprega. Na osnovu analitičkih istraživanja formirani su egzaktni i približni matematički modeli za određivanje radnog i kritičnog napona u podnožju zupca merodavnih za proveru zapreminske čvrstoće zupca zupčanika.
