Abstract
Odgovarajućom nosivošću zupčanih parova osigurava se da ne dođe do nastanka oštećenja koja mogu utjecati na normalan rad unutar predviđenog životnog vijeka. S obzirom da se opterećenje s pogonskog na gonjeni zupčanik prenosi na način da mijenja svoj pravac djelovanja, položaj i intenzitet, mijenja se i naprezanje u korijenu zuba zupčanika koje može izazvati lom zuba uslijed zamora materijala. U radu je primjenom metode konačnih elemenata pomoću programskog paketa Abaqus određen ciklus naprezanja u korijenu zuba. Pretpostavljeno je da su oba zupčanika izrađena od istog materijala te da je materijal homogen, izotropan i linearno elastičan. Analizirani su cilindrični zupčanici s ravnim simetričnim i asimetričnim zubima te je provedena usporedba njihovih ciklusa naprezanja. Kako bi sama računalna simulacija što realnije odgovarala stvarnim uvjetima rada zupčanog para, u obzir su uzeti i faktori poput centrifugalnog opterećenja i/ili trenja te je analiziran i njihov utjecaj. Određeno je mjesto maksimalnog naprezanja u korijenu zuba, tj. kritični presjek te je uspoređeno s mjestom maksimalnog naprezanja prema normi HRN EN ISO 6336-3.
Abstract (english)
By choosing the appropriate load capacity of gear pairs it is ensured that no damage occurs which could affect normal operation within the expected service life. Since the load from the operating to the driven gear is transferred in a way that it changes it's direction, position and intensity, the tooth root stress also changes, which can cause breakage of the teeth due to bending fatigue. In thesis, the tooth root stress cycle was determined using finite element method and Abaqus software package. It s assumed that both gears are made of the same material which is considered to be homogenous, isotropic and linearly elastic. Cylindrical gears with symmetric and assymetric involute teeth were analyzed and their stress cycles were compared. In order to conduct the simulation as accurately as possible, factors such as centrifugal load and/or friction were taken into account and their influence on the tooth root stress cycle was analyzed. The place of maximum principal stress in tooth root, i.e. the critical cross section, was determined and compared with the place of maximum stress according to the standard HRN EN ISO 6336-3.
