Ako vypo\u010d\u00edtate po\u017eadovan\u00fd prevodov\u00fd pomer a zvol\u00edte po\u010det zubov?<\/h2>\n

Z\u00e1kladn\u00fdm krokom je v\u00fdpo\u010det prevodov\u00e9ho pomeru a v\u00fdber po\u010dtu zubov. Priamo premieta va\u0161e potreby r\u00fdchlosti a kr\u00fatiaceho momentu do fyzickej kon\u0161trukcie. Ak to urob\u00edte zle, v\u00e1\u0161 stroj nebude fungova\u0165 tak, ako m\u00e1.<\/p>\n

Tento proces je jednoduch\u0161\u00ed, ako sa zd\u00e1. Za\u010d\u00edna sa po\u017eadovan\u00fdmi vstupn\u00fdmi a v\u00fdstupn\u00fdmi r\u00fdchlos\u0165ami. Odtia\u013e prejdeme k fyzick\u00fdm prevodov\u00fdm stup\u0148om.<\/p>\n

Prevodov\u00fd pomer (i) = zuby na hnacom ozubenom kolese (Z2) \/ zuby na pastorku (Z1)<\/code><\/p>\n

Pri prevodovom pomere 3:1 by ste mohli pou\u017ei\u0165 pastorky s 20 zubami a hnacie ozuben\u00e9 koleso so 60 zubami. To je dobr\u00fd v\u00fdchodiskov\u00fd bod.<\/p>\n
