Three stage reduction gear with parallel exit shafts

Zadatak je konstruiranje trostupanjskog reduktora sa kosim zubima. Materijal za izradu vratila i zupčanika je C4130. materijal za izradu kućišta reduktora je SL300. Svaki stupanj je izračunat zasebno, te provjeren da ne smeta jedan u odnosu na drugi. Problem je bio između drugog i trećeg stupnja, te je isti riješen većim razmakom osi. Pogonski zupčanici su napravljeni u sklopu sa vratilom, a gonjeni su napravljeni odvojeno. Napravljena je kontrola vratila, nakon čega su izabrani odgovarajući ležajevi. Spoj gonjenih zupčanika sa vratilom je preko pera. Glavna obrada vratila i zupčanika je kovanje u ukovnju zbog velikih promjera. Nakon toga ide tokarenje i glodanje prema potrebi, te izrada prijelaznih utora. Za podmazivanje zupčanika i ležajeva je napravljen toplinski proračun, te je odabran sistem podmazivanja sa uranjanjem zupčanika u ulje.The task is to construct a three-stage reducer with oblique teeth. The material for making the shaft and gear is C4130. The material for making the gearbox housing is SL300. Each degree was calculated separately, and checked not to interfere with each other. The problem was between the second and third degree, and the same was solved by a larger axis spacing. The drive gears are made in conjunction with the shaft, and the drive gears are made separately. The shaft control was made, after which the appropriate bearings were selected. The connection of the driven gears with the shaft is through the key. The main machining of shafts and gears is forging in forging due to large diameters. This is followed by turning and milling as needed, and making transition slots. A thermal calculation was made for the lubrication of gears and bearings, and a lubrication system with immersion of the gears in oil was selected
