Abstract
U ovom radu je projektiran dvostupanjski vertikalni koaksijalni reduktor snage 75 kW prijenosnog omjera i = 22,5. Svi elementi reduktora, vratila, zupčanici i leţajevi dimenzionirani su prema uvjetima zadatka te zadovoljavaju sve traţene uvjete. Vratila su uleţištena u stoţastim valjnim leţajevima zbog aksijalnih sila koje se pojavljuju u zahvatu zupčanika sa kosim zubima. Proračunati su uvjeti podmazivanja te je izabrano odgovarajuće ulje. Proračun hlaĎenja pokazao je da ventilator za hlaĎenje reduktora nije dovoljan. Zbog toga je prilikom ugradnje reduktora potrebno osigurati odgovarajuću pumpu i hladnjak ulja.
Abstract (english)
This final paper deals with the design of a two-stage vertical coaxial reduction gear unit with 75 kW rated power and a transmission ratio of I = 22,5. All the parts of the gear unit, e.g. shafts, gears and bearings have been calculated according to the rated power and fulfill all the demands that have been placed on the assignment. The shafts are laid in taper roller bearings due to the axial forces resulting from the mesh of helical gears. The lubrication conditions have been calculated and an appropriate oil was selected. The heat balance calculation has shown that the intended fan cooling system would be inadequate, and therefore it is necessary to supply an adequate oil pump and cooler when the gear unit is being installed
