PLANETARY GEAR ON CNC MACHINES

U ovom radu navode se informacije o planetarnim prijenosnicima snage i gibanja općenito i kod CNC strojeva, rješava se proračun vezan za dimenzije te kontrole naprezanja. Početkom svake nove industrijske revolucije rasla je potreba za načinima prijenosa snage i gibanja. Tako se danas pojavljuju različiti prijenosnici, reduktori i multiplikatori koji imaju razne primjene u praksi. Sve češće se pojavljuju i tzv. Planetarni prijenosnici koji zbog svojih prednosti i mogućnosti izvedbe uvelike pomažu boljoj iskoristivosti strojeva. Svoju primjenu planetarni prijenosnici osim kod CNC strojeva nalaze u industriji obrade metala, drvnoj industriji, autoindustriji i mnogim drugima. Baš zbog jako velikih prijenosnih omjera, a malih dimenzija idealni su za primjenu kod CNC strojeva kao što su tokarilica, glodalica i bušilica.In this work informations about planetary gear sets are mentioned in general and as a part of Computer Numerical Control.Furthermore, a budget of dimensions is solved as same as budget of strain control In the beginning of each industrial revolutions it was necessary to find nwe ways to transfer motion and power. Many kind of gears with different purpose appear to help human in daily job. Planetary gear sets with its advantages and possibillities of performance become more useful and have its use in metal processing industry, car industry, aviation industry, wood processing industry and many others. Just because portable radio and yet small dimensions planetary gear sets are apposite for Computer Numerical Control machines as drill, mill and lath
