Z\u00e1vitovkov\u00e9 prevody maj\u00fa menej prenosov\u00fdch pl\u00f4ch, tak\u017ee existuje menej oblast\u00ed na poruchu. Napriek tomu nedok\u00e1\u017eu zvr\u00e1ti\u0165 tok energie. Je to preto, \u017ee trenie medzi z\u00e1vitovkou a kolesom znemo\u017e\u0148uje sp\u00e4tn\u00fd pohyb z\u00e1vitovky.
Z\u00e1vitovkov\u00e9 prevody sa \u0161iroko pou\u017e\u00edvaj\u00fa vo v\u00fd\u0165ahoch, zdv\u00edhac\u00edch zariadeniach a zdvih\u00e1koch.

Z\u00e1vitovkov\u00e9 prevody s\u00fa navrhnut\u00e9 tak, aby dosiahli ur\u010dit\u00fd reduk\u010dn\u00fd pomer.

Tieto dva hriadele s\u00fa zvy\u010dajne umiestnen\u00e9 pod uhlom, ktor\u00fd zabezpe\u010duje spr\u00e1vne zarovnanie. Z\u00e1vitovkov\u00e9 prevody maj\u00fa rozostup srdc\u00ed zodpovedaj\u00faci rozmeru r\u00e1mu. Rozostup srdc\u00ed ozuben\u00e9ho kolesa a z\u00e1vitovkov\u00e9ho hriade\u013ea ur\u010duje axi\u00e1lny rozstup. Napr\u00edklad, ak s\u00fa ozuben\u00e9 koles\u00e1 nastaven\u00e9 na radi\u00e1lnu d\u013a\u017eku, je potrebn\u00fd kompaktnej\u0161\u00ed vonkaj\u0161\u00ed priemer.
Klzn\u00fd pohyb z\u00e1vitovkov\u00fdch prevodov zni\u017euje ich \u00fa\u010dinnos\u0165. Z\u00e1rove\u0148 v\u0161ak zais\u0165uje pokojn\u00fd chod. Klzn\u00fd pohyb obmedzuje \u00fa\u010dinnos\u0165 z\u00e1vitovkov\u00fdch prevodov na 30% a\u017e 50%. V tomto \u010dl\u00e1nku sa uv\u00e1dza nieko\u013eko techn\u00edk na minimaliz\u00e1ciu trenia a vytvorenie vynikaj\u00facich vstupn\u00fdch a v\u00fdstupn\u00fdch medzier. \u010coskoro pochop\u00edte, pre\u010do s\u00fa takou flexibilnou vo\u013ebou pre va\u0161e potreby! Ak teda uva\u017eujete o k\u00fape z\u00e1vitovkov\u00e9ho prevodu, ur\u010dite si pre\u010d\u00edtajte tento \u010dl\u00e1nok, aby ste sa dozvedeli viac o jeho vlastnostiach!
Jedno uskuto\u010dnenie z\u00e1vitovkov\u00e9ho prevodu je vysvetlen\u00e9 na obr. 19 a 20. Alternat\u00edvne uskuto\u010dnenie syst\u00e9mu pou\u017e\u00edva jeden motor a jeden z\u00e1vitovkov\u00fd prevod 153. Z\u00e1vitovkov\u00fd prevod 153 ot\u00e1\u010da ozuben\u00fdm kolesom, ktor\u00e9 poh\u00e1\u0148a rameno 152. Rameno 152 n\u00e1sledne pohybuje zostavou \u0161o\u0161ovky\/zrkadla o r\u00f4zne uhly nato\u010denia. Jednotka riadenia motora 114 potom sleduje uhol nato\u010denia zostavy \u0161o\u0161ovky\/zrkadla 10 vzh\u013eadom na referen\u010dn\u00e9 umiestnenie.

Pou\u017eit\u00e9 mazivo z\u00e1vis\u00ed od druhu plastu, preto\u017ee mnoho druhov plastov reaguje na uh\u013eovod\u00edky nach\u00e1dzaj\u00face sa v be\u017enom mazive.
