20.500.12556/RUL-133411 Raziskava vplivnih veličin in preračun krčnega naseda z narebričeno gredjo Research of influential parameters and calculation of knurled interference fit V avtomobilski industriji se pogosto srečujemo z grednimi zvezami, saj so učinkovite pri prenašanju vrtilnega momenta. Ena od njih je zveza gredi in pesta s krčnim nasedom z narebričeno gredjo. V nalogi smo s pomočjo MKE analize in eksperimenta poskusili preučiti veličine, ki vplivajo na take zveze, in predlagali enačbo, s katero bi lahko izračunali maksimalni vrtilni moment in vtisno silo. Osredotočili smo se na tri materiale, in sicer jeklo (C45), aluminijevo zlitino (AlMgSi1) in medenino (CuZn5). Za razliko od klasičnega krčnega naseda smo morali upoštevati prenos momenta tako preko trenja kot tudi preko oblike. Problem popisa te zveze so plastične deformacije, ki se pojavijo pri vtiskanju gredi. In the automotive industry, we often deal with shaft couplings because they are very effective at transferring torque. One type of shaft coupling is one with a knurled interference fit. In this thesis we examine the different variables which influence the shaft coupling and propose an equation for calculating maximum torque and push-in force respectively. We focused on three different materials including steel (C45), aluminium alloy (AlMgSi1) and brass (CuZn5). Unlike with a classical interference fit, we must also consider the transfer of torque via the shape of the coupling itself as well as via friction. The problem of evaluating this joint are the plastic deformations which occur during the shaft joining. krčni nased krčni nased z narebričeno gredjo MKE analiza analitiči izračun maksimalni moment vtisna sila interference fit knurled interference fit FEM analysis analytical calculation maximum torque push in force true false false [J.
