Abstract

U radu je analiziran ciklus naprezanja u korijenu gonjenog zupčanika, koji je opterećen momentom uvijanja, koristeći se metodom konačnih elemenata. Budući da se zupčanici u svom radu rotiraju, u obzir se uzimao utjecaj centrifugalne sile. Ciklusi naprezanja određeni su prvo za zupčanike bez korekcije, a zatim i za zupčanike s linearnom te paraboličnom korekcijom tjemenog dijela zuba. Dobiveni ciklusi naprezanja međusobno su uspoređeni kako bi se promotrio utjecaj korekcije tjemenog dijela zuba na naprezanje u korijenu. U radu su analizirani zupčanici s asimetričnim zubima, koji su izrađeni od istog čelika i geometrijski su identični.

Abstract (english)

In this paper, tooth root stress cycle of a driven gear was analized using finite element method. Since gears are moving parts which are rotating, centrifugal force was taken into account. Stress cycle was first determened for gears without any tip relief modifitacion and later for gears with linear and parabolic tip relief modification. Analized stress cycles were compared to determine the effect that tip relief modification has on tooth stress cycle. Analized gears have asymmetric teeth, are made of the same steel and are geometrically identical.
