20.500.12556/DKUM-15969 ZASNOVA IN PRERAČUN POGONA SLEDILNIKA SONCA Z VELIKIM AKSIALNIM KROGLIČNIM LEŽAJEM BASIC CONCEPT AND CALCULATION OF SUN TRACKER DRIVE USING LARGE SLEWING BEARING Problematika te diplomske naloge je sledenje fotovoltaičnih panelov soncu. Gonilo za obračanje okoli vertikalne osi, ki ga obravnava ta diplomska naloga je alternativa tistega iz že obstoječega projekta. Preverjena je možnost uporabe velikega aksialnega krogličnega ležaja z valjastim ozobjem, ki ga preko pastorka poganja elektromotor. Pri tem je opravljen trdnostni preračun zobniške dvojice in samega ležaja. Preračun zobniške dvojice je bil opravljen s pomočjo trdnostnih enačb iz univerzitetnega učbenika, preračun ležaja pa v namenskem računalniškem programu razvitem na Fakulteti za strojništvo Maribor. Rezultati pokažejo ustreznost zasnovanega gonila, kljub temu pa zasnova iz izvornega projekta, ki predvideva polžasto gonilo predstavlja ugodnejšo izvedbo. The problem of this thesis is tracking the sun with a photovoltaic panel. The vertical axis rotation drive used in this thesis is an alternative to an already existing project. I have examined the possibility of using a large axial ball bearing with integrated gears, that is driven by an electric motor via a pinion. There was conducted a structural strength calculation of both gears and ballbearing. The gears were calculated using equations from an university textbook, calculation of the ball bearing however was conducted using a special computer program developed in Faculty of mechanical engineering Maribor. The results show that altough this drive is structuraly sound it doesn´t represent a favorable sollution. The sollution from an existing project which uses a worm gear proves to be a better one. sledilnik sonca konstruiranje velik aksialni kroglični ležaj sun tracker construction large axial ball bearing true true false [M.
