Construction of flange mounted planetary gearbox for electric motor with peak power of 508 KW

U radu je objašnjeno, proračunato, dimenzionirano i modelirano konstrukcijsko rješenje planetnog reduktora sa svrhom spajanja na elektromotor električnog superautomobila putem ozubljenog vratila. Prema definiranim ulaznim parametrima odabrana je izvedba s jednim stupnjem prijenosa, gdje će zakočeni član biti vanjski zupčanik s unutarnjim Kroz princip rada planetnog reduktora, njegove prednosti i nedostatke te problematiku, u koracima je napravljen potreban proračun i dimenzioniranje razmatranog sklopa. Kinematska analiza dala je meusobni odnos gibanja pojedinih članova reduktora, ali i gibanja u odnosu na vanjsku referencu, pri čemu je bilo potrebno zadovoljiti tri glavna kriterija, tipična za sve planetne reduktore. Proračuni čvrstoće zupčanika, vratila i ležajeva izvršeni su i predstavljeni kronološki i kao takvi bili su podloga za konstruiranje trodimenzionalnog modela i popratne tehničke dokumentacije.In the following thesis, the planetary gearbox is explained, calculated, dimensioned and designed with the purpose of connecting to electric supercar using a toothed shaft. According to the defined input parameters, it was decided that one-stage gear transmission will be used, where the locked gear member will be an external ring gear with internal toothing. Through the working principle of planetary gear set unit operation, its advantages, disadvantages and the overall problematic, the required calculation and dimensioning have been made in steps. The kinematic analysis has given the mutual relation between the motion of certain reducer parts, but also the motion in relation to the external reference, where it was necessary to fulfill the three main criteria of the epicyclic reducers. Gear, shaft and bearing calculations were performed and presented chronologically and as such they were the basis for the design of a three-dimensional model and the accompanying technical documentation
