Abstract
Zadatak je bio konstruirati trostupanjski vertikalni reduktor, za primjenu u industriji. Zupčanici su izvedeni na sva tri stupnja s kosim ozubljenjem, jednakog kuta nagiba. Za sva vratila i vratila sa zupčanikom kao i gonjeni zupčanici izraditi će se od materijala Č.4320. Pogonski zupčanici izraditi će se od jednog komada materijala zajedno s vratilom, dok će se gonjeni zupčanici osigurati pomoću uložnih pera. Gonjeni zupčanici izraditi će se kovanjem u ukovnju zbog velikih dimenzija pa je na taj način velika ušteda i manjak škarta materijala prilikom strojne obrade. Elementi reduktora biti će obrađeni strojnom obradom najviše tokarenjem, dok će se kućište obraditi CNC obradnim centrom. Zubi zupčanika će se brusiti radi boljeg i tišeg rada reduktora te dugotrajnijeg vijeka trajanja. Promjeri na kojima će biti ležajevi i radijalna brtva obraditi će se finim tokarenjem kako bi se postigla finija površina hrapavosti. Time postižemo bolje prijanjanje ležajeva, lakšu i precizniju montažu te time mirniji rad. Ležajevi su izračunati pomoću SKF kalkulatora kako bi odgovarali po dinamičkom opterećenju kao i na kraju minimlanim vijekom trajnosti. Vratila su proračunata i izvršena je kontrola čvrstoće kako bi izdržala opterećenja. Podmazivanje i hlađenje zupčanika i ležajeva je toplinski proračunato i odabran je sistem kao i ulje koje odgovara potrebama reduktora. Korisnik mora naknadno nabaviti i montirati sistem.
Abstract (english)
The task was to construct a three-stage vertical reducer, for industrial application. The gears are made in all three stages with oblique gearing, equal angle of inclination. All shafts and gear shafts as well as driven gears will be made of material Č.4320. The drive gears will be made of one piece of material together with the shaft, while the driven gears will be secured with inserts. The driven gears will be made by forging in the forging due to the large dimensions, so there is a great saving and shortage of material waste during machining. The elements of the gearbox will be machined mostly by turning, while the housing will be machined with a CNC machining center. The gear teeth will be ground for better and quieter gear operation and longer service life. The diameters at which the bearings and radial seal will be machined by fine turning to achieve a finer roughness surface. This achieves better bearing adhesion, easier and more precise assembly and thus quieter operation. The bearings were calculated using an SKF calculator to match the dynamic load as well as ultimately the minimum service life. The shafts were calculated and a strength check was performed to withstand the loads. Lubrication and cooling of gears and bearings is heat calculated and the system is selected as well as the oil that meets the needs of the gearbox. The user must subsequently procure and install the system.
