20.500.12556/RUL-185856 Vpliv geometrijskih odstopanj na napetosti valjastih zobniških dvojic Influence of Geometric Deviations on Stress Distribution in Cylindrical Gear Pairs V okviru magistrske naloge je bil obravnavan vpliv geometrijskih napak na napetosti valjastih zobniških dvojic. Poseben poudarek je bil na primerjavi analitično določenih napetosti po standardu ISO 6336 s tistimi pridobljenimi z numeričnimi simulacijami. Analizirane so bile različne vrste geometrijskih odstopanj in njihov vpliv. Za namen raziskave so bili izdelani 3D modeli zobniških dvojic, v katere so bila sistematično vključena izbrana geometrijska odstopanja. Virtualni eksperimenti so bili izvedeni v programskem okolju ABAQUS/Standard. Dobljeni rezultati so bili primerjani z analitičnimi izračuni za zobnike osmega tolerančnega razreda natančnosti. Ugotovljeno je bilo, da standard v večini primerov podaja konservativne rezultate, ki v praksi dopuščajo določeno varnostno rezervo. V skrajnih primerih, kjer so bila odstopanja najvišja, so bile dobljene napetosti med seboj primerljive. Takšna stanja so v realni inženirski praksi malo verjetna. As part of this master's thesis, the influence of geometric deviations on the stresses in cylindrical gear pairs was examined. Special emphasis was placed on comparing analytically determined stresses according to the ISO 6336 standard with those obtained through numerical simulations. Various types of geometric deviations and their impacts were analyzed. For the research, 3D models of gear pairs were created, into which selected geometric deviations were systematically incorporated. Virtual experiments were performed using the ABAQUS/Standard software environment. The obtained results were compared with analytical calculations for gears of the eighth accuracy tolerance class. It was found that in most cases, the standard provides conservative results, which allow for a certain safety margin in practice. In extreme cases, where the deviations were the highest, the resulting stresses were comparable. Such conditions are unlikely to occur in real engineering practice. valjasti zobniki geometrijska odstopanja ISO 6336 bočni tlak korenska napetost numerične simulacije cylindrical gears geometric deviations ISO 6336 contact pressure tooth root stress numerical simulations true false false [M.
