Z\u00e1vitovkov\u00fd prevod dok\u00e1\u017ee dosiahnu\u0165 mas\u00edvne reduk\u010dn\u00e9 pomery s malou energiou. Zv\u00e4\u010d\u0161en\u00edm obvodu kolesa m\u00f4\u017ee z\u00e1vitovka v\u00fdrazne zv\u00fd\u0161i\u0165 svoj kr\u00fatiaci moment a zn\u00ed\u017ei\u0165 svoju r\u00fdchlos\u0165. Konven\u010dn\u00e9 prevody vy\u017eaduj\u00fa nieko\u013eko prevodov na dosiahnutie rovnak\u00e9ho reduk\u010dn\u00e9ho pomeru. Z\u00e1vitovkov\u00e9 prevody maj\u00fa menej posuvn\u00fdch komponentov, tak\u017ee existuje menej miest na poruchu. Napriek tomu nedok\u00e1\u017eu zvr\u00e1ti\u0165 tok v\u00fdkonu. Je to preto, \u017ee trenie medzi z\u00e1vitovkou a kolesom znemo\u017e\u0148uje pohyb z\u00e1vitovky sp\u00e4\u0165.
Z\u00e1vitovkov\u00e9 prevody sa be\u017ene pou\u017e\u00edvaj\u00fa vo v\u00fd\u0165ahoch, zdv\u00edhac\u00edch zariadeniach a zdvih\u00e1koch. S\u00fa obzvl\u00e1\u0161\u0165 u\u017eito\u010dn\u00e9 v aplik\u00e1ci\u00e1ch, kde je d\u00f4le\u017eit\u00e1 r\u00fdchlos\u0165 zastavenia. M\u00f4\u017eu by\u0165 kombinovan\u00e9 s kompaktnej\u0161\u00edmi brzdami pre zaistenie ur\u010ditej bezpe\u010dnosti, ale nemali by sa spolieha\u0165 na ne ako na hlavn\u00fd brzdov\u00fd syst\u00e9m. Zvy\u010dajne s\u00fa samosvorn\u00e9, tak\u017ee s\u00fa vynikaj\u00facou vo\u013ebou pre mnoho aplik\u00e1ci\u00ed. Maj\u00fa tie\u017e mnoho v\u00fdhod, medzi ktor\u00e9 patr\u00ed zv\u00fd\u0161en\u00e1 \u00fa\u010dinnos\u0165 a bezpe\u010dnos\u0165.
Z\u00e1vitovkov\u00e9 prevody s\u00fa navrhnut\u00e9 na dosiahnutie odli\u0161n\u00e9ho reduk\u010dn\u00e9ho pomeru. Zvy\u010dajne s\u00fa umiestnen\u00e9 medzi vstupn\u00fdm a v\u00fdstupn\u00fdm hriade\u013eom motora a z\u00e1\u0165a\u017ee. Tieto dva hriadele s\u00fa zvy\u010dajne umiestnen\u00e9 pod uhlom, ktor\u00fd zabezpe\u010duje vhodn\u00e9 zarovnanie. Z\u00e1vitovkov\u00e9 prevody maj\u00fa stredov\u00fa vzdialenos\u0165 zodpovedaj\u00facu rozmeru r\u00e1mu. Srdcov\u00e1 vzdialenos\u0165 zariadenia a z\u00e1vitovkov\u00e9ho hriade\u013ea ur\u010duje axi\u00e1lny rozstup. Napr\u00edklad, ak s\u00fa ozuben\u00e9 koles\u00e1 umiestnen\u00e9 v radi\u00e1lnej vzdialenosti, je potrebn\u00fd men\u0161\u00ed vonkaj\u0161\u00ed priemer.
Klzn\u00fd kontakt z\u00e1vitovkov\u00fdch prevodov zni\u017euje v\u00fdkon. Z\u00e1rove\u0148 v\u0161ak zaru\u010duje tich\u00fa prev\u00e1dzku. Klzn\u00fd \u00fa\u010dinok obmedzuje v\u00fdkon z\u00e1vitovkov\u00fdch prevodov na 30% a\u017e 50%. Tu je uveden\u00fdch nieko\u013eko takt\u00edk na minimaliz\u00e1ciu trenia a vytvorenie dobr\u00fdch vstupn\u00fdch a v\u00fdstupn\u00fdch medzier. \u010coskoro pochop\u00edte, pre\u010do s\u00fa pre v\u00e1s takou v\u0161estrannou vo\u013ebou! Ak teda uva\u017eujete o k\u00fape z\u00e1vitovkov\u00e9ho zariadenia, ur\u010dite si pre\u010d\u00edtajte tento \u010dl\u00e1nok, aby ste sa dozvedeli viac o jeho vlastnostiach!
Uskuto\u010dnenie z\u00e1vitovkov\u00e9ho zariadenia je vysvetlen\u00e9 na obr. 19 a 20. Alternat\u00edvne uskuto\u010dnenie programu vyu\u017e\u00edva jeden motor a jeden z\u00e1vitovkov\u00fd mechanizmus 153. Z\u00e1vitovkov\u00fd mechanizmus 153 ot\u00e1\u010da zariadenie, ktor\u00e9 poh\u00e1\u0148a rameno 152. Rameno 152 n\u00e1sledne pohybuje zostavou \u0161o\u0161ovky\/zrkadla 10 o r\u00f4zne uhly naklonenia. Jednotka riadenia motora 114 potom sleduje uhol naklonenia zostavy \u0161o\u0161ovky\/zrkadla 10 vo vz\u0165ahu k referen\u010dnej polohe.
Z\u00e1vitovkov\u00e9 koleso a z\u00e1vitovka s\u00fa rovnako vyroben\u00e9 z kovu. Mosadzn\u00e1 z\u00e1vitovka a koleso s\u00fa v\u0161ak vyroben\u00e9 z mosadze, \u010do je \u017elt\u00fd kov. Ich v\u00fdber maz\u00edv je ove\u013ea v\u0161estrannej\u0161\u00ed, ale v\u010faka \u017eltej oceli s\u00fa obmedzen\u00e9 pr\u00edsadami. Plasty na kovov\u00fdch z\u00e1vitovkov\u00fdch prevodoch sa zvy\u010dajne nach\u00e1dzaj\u00fa v aplik\u00e1ci\u00e1ch s n\u00edzkym za\u0165a\u017een\u00edm. Pou\u017eit\u00e9 mazivo z\u00e1vis\u00ed od druhu plastu, preto\u017ee mnoh\u00e9 druhy plastov reaguj\u00fa na uh\u013eovod\u00edky nach\u00e1dzaj\u00face sa v be\u017enom mazive. Z tohto d\u00f4vodu potrebujete nereakt\u00edvne mazivo.<\/p>\n![\"\u010c\u00edna](\"https:\/\/img.hzpt.com\/img\/worm-shaft\/wormshaft-l1.webp\")
