Preparation of technical documentation for gearbox calculation

Reduktori pronalaze široku primjenu u industriji tj. proizvodnim pogonima. Reduktori spadaju u prijenosnike snage i gibanja te kao takvi prenose snagu i gibanje od pogonskih do radnih strojeva, a radni strojevi najčešće se povezani sa metalnom, drvnom i plastičnom industrijom. Prijenosnike snage i gibanja podijelilo se na na mehaničke, hidrauličke, pneumatske i električne a podjela se napravila na temelju okretnog momenta koji oni prenose. Kada govorimo o jednostupanjskom reduktoru on nam služi za reduciranje brzine vrtnje sa pogonskog stroja na radni stroj. Hipoteza ovog rada temelji se na pretpostavci kako se pravilnom upotrebom standardnih formula postići izlazni zakretni moment od M = 121 Nm što se i dokazalo. Pri izradi ovog rada koristila se matematička metoda za proračunavanje konstrukcijskih elemenata dok se analitička metoda koristila za analizu razni formula i jednadžbi te odabir najoptimalnijih za naš slučaj. Koristila se i metoda modeliranja kod simulacija 3D dijelova jednostupanjskog reduktora. Ovim radom proračunali su se i oblikovali svi elementi reduktora od zupčanika, vratila, ležaja i kućišta. Za potrebne elemente reduktora izvršio se i kontrolni proračun.Reducers are widely used in industry, ie in production plants. Reducers are power and motion transmitters and as such transmit power and motion from drive to working machines, and working machines are most often associated with the metal, wood and plastic industries. We divided power and motion transmitters into mechanical, hydraulic, pneumatic and electrical, based on the torque they transmit. When we talk about a single-stage reducer, it serves to reduce the speed from the drive machine to the working machine. The hypothesis of this paper is based on the assumption that the correct use of standard formulas achieves an output torque of M = 121 Nm, which has beenproven. In making this paper, a mathematical method was used to calculate the structural elements, while the analytical method was used to analyze various formulas and equations and select the most optimal for our case. The modeling method was also used in simulations of 3D parts of a single-stage reducer. This work calculated and designed all the elements of the gearbox from gears, shafts, bearings and housings. A control calculation was performed for the required gear elements
