Princ\u00edp fungovania plan\u00e9tov\u00fdch prevodoviek<\/h2>\n

Aby in\u017einieri a oper\u00e1tori skuto\u010dne ocenili mechanick\u00fa nadradenos\u0165 s\u00e9rie SD, musia z\u00e1kladne pochopi\u0165 vn\u00fatorn\u00fa kinematiku, ktor\u00e1 definuje fungovanie plan\u00e9tov\u00e9ho prevodov\u00e9ho syst\u00e9mu. \u0160truktur\u00e1lna konfigur\u00e1cia sa presne podob\u00e1 slne\u010dnej s\u00fastave, pozost\u00e1vaj\u00facej z troch prim\u00e1rnych kovov\u00fdch komponentov pracuj\u00facich v dokonalej fyzickej harm\u00f3nii.
