Abstract (Croatian)
U ovom radu analizirati će se ciklus naprezanja korijena zuba opterećenog zadanim momentom. Odrediti će se mjesto maksimalnog naprezanja u korijenu zuba, te usporediti sa mjestom očekivanog maksimalnog naprezanja po ISO 6336. Budući da se zupčanici rotiraju brzinom vrtnje od 10 000 min-1, uzeti će se u obzir i utjecaj centrifugalne sile na promatrani korijen zuba te usporediti sa ciklusom naprezanja bez uračunate centrifugalne sile. Debljina tankog vijenca mijenjati će se tijekom analiza kako bi se promotrio utjecaj koji ima na ciklus naprezanja tokom prolaska zuba kroz zahvat. Također će se promatrati utjecaj veličine sektorskog otvora zupčanika od početnog sektorskog otvora koji obuhvaća sedam zubi do krajnje vrijednosti od jednog zuba. Nakon provedene analize i usporedbe svih spomenutih ciklusa, dobivene vrijednosti usporediti će se s proračunom preko norme ISO 6336.
Abstract
In this paper, gear stress analysis will be carried out to determine a place of maximum root bending stress of a cylindricall gear tooth. Location of the maximum bending stress will then be compared with the place of expected maximum bending stress according to ISO 6336 standard. Since both gears are rotating with a speed of 10 000 rpm, centrifugal force will also be taken into account and compared to results where no centrifugal force was involved. Thickness of a thin rim will also vary to determine the effect it has on a stress cycle, as will the size of a sector opening, starting with the initial value of seven-tooth span to one-tooth span. After analyzing and comparing all of cycles mentioned above, results will be compared with those obtained through ISO 6336 standard.
