Tu je nieko\u013eko tipov na v\u00fdber z\u00e1vitovkov\u00e9ho hriade\u013ea a ozuben\u00e9ho kolesa pre v\u00e1\u0161 projekt!... a nieko\u013eko faktorov, ktor\u00e9 treba ma\u0165 na pam\u00e4ti.<\/p>\n
Profil zubov zariadenia 22 na z\u00e1vitovkovom hriadeli dvadsa\u0165 sa l\u00ed\u0161i od profilu \u0161tandardn\u00e9ho ozuben\u00e9ho kolesa. Je to preto, \u017ee zuby zariadenia 22 s\u00fa konk\u00e1vne, \u010do umo\u017e\u0148uje lep\u0161iu interakciu so z\u00e1vitmi z\u00e1vitovkov\u00e9ho hriade\u013ea dvadsa\u0165. Uhol n\u00e1behu z\u00e1vitovky vedie k samosvoreniu z\u00e1vitovky, \u010d\u00edm sa zabr\u00e1ni sp\u00e4tn\u00e9mu pohybu. Napriek tomu tento samosvorn\u00fd syst\u00e9m nie je \u00faplne d\u00f4veryhodn\u00fd. Z\u00e1vitovkov\u00e9 prevody sa pou\u017e\u00edvaj\u00fa v nieko\u013ek\u00fdch priemyseln\u00fdch aplik\u00e1ci\u00e1ch, od v\u00fd\u0165ahov a\u017e po ryb\u00e1rske navijaky a elektrick\u00e9 posil\u0148ova\u010de riadenia automobilov.
Nov\u00e9 zariadenie je nain\u0161talovan\u00e9 na hriadeli, ktor\u00fd je upevnen\u00fd olejov\u00fdm tesnen\u00edm. Na in\u0161tal\u00e1ciu nov\u00e9ho zariadenia mus\u00edte najprv odstr\u00e1ni\u0165 star\u00e9 ozuben\u00e9 koleso. Potom mus\u00edte odskrutkova\u0165 dve skrutky, ktor\u00e9 dr\u017eia ozuben\u00e9 koleso na hriadeli. \u010ealej mus\u00edte odstr\u00e1ni\u0165 nosi\u010d lo\u017eiska z v\u00fdstupn\u00e9ho hriade\u013ea. Po odstr\u00e1nen\u00ed z\u00e1vitovkov\u00e9ho zariadenia mus\u00edte odskrutkova\u0165 poistn\u00fd kr\u00fa\u017eok. Potom nain\u0161talujte ku\u017eele lo\u017eiska a rozperu hriade\u013ea. Uistite sa, \u017ee hriade\u013e je spr\u00e1vne utiahnut\u00fd, ale neu\u0165ahujte z\u00e1tku pr\u00edli\u0161 silno.
Aby ste predi\u0161li pred\u010dasn\u00fdm poruch\u00e1m, pou\u017e\u00edvajte vhodn\u00e9 mazivo pre dan\u00fd typ z\u00e1vitovkov\u00e9ho zariadenia. Na klzn\u00fd pohyb z\u00e1vitovkov\u00fdch prevodov je potrebn\u00fd olej s vysokou viskozitou. V dvoch tretin\u00e1ch aplik\u00e1ci\u00ed boli maziv\u00e1 nedostato\u010dn\u00e9. Ak je z\u00e1vitovka mierne za\u0165a\u017een\u00e1, m\u00f4\u017ee by\u0165 posta\u010duj\u00faci olej s ni\u017e\u0161ou viskozitou. Na udr\u017eanie z\u00e1vitovkov\u00fdch prevodov v dobrom stave je zvy\u010dajne potrebn\u00fd olej s vysokou viskozitou.
\u010eal\u0161ou mo\u017enos\u0165ou je upravi\u0165 po\u010det zubov okolo zariadenia 22, aby sa zn\u00ed\u017eila r\u00fdchlos\u0165 v\u00fdstupn\u00e9ho hriade\u013ea. To sa d\u00e1 dosiahnu\u0165 nastaven\u00edm ur\u010dit\u00e9ho pomeru (napr\u00edklad 5 alebo 10 ot\u00e1\u010dok motora) a zodpovedaj\u00facou \u00fapravou vyklenutia z\u00e1vitovky. Tento postup zn\u00ed\u017ei r\u00fdchlos\u0165 v\u00fdstupn\u00e9ho hriade\u013ea na po\u017eadovan\u00fa hodnotu. Vyklenutie z\u00e1vitovky by malo by\u0165 prisp\u00f4soben\u00e9 po\u017eadovan\u00e9mu axi\u00e1lnemu st\u00fapaniu.<\/p>\n
Pri v\u00fdbere z\u00e1vitovkov\u00e9ho zariadenia zv\u00e1\u017ete nasleduj\u00face faktory. Ide o vysoko\u00fa\u010dinn\u00e9, tich\u00e9 prevody.

Z\u00e1vitovkov\u00fd hriade\u013e je konfigurovan\u00fd tak, aby bol podopret\u00fd v r\u00e1me 24.

Z\u00e1vitovkov\u00fd hriade\u013e a zariadenie 22 sa nemusia zda\u0165 v kontakte alebo do seba viac zasahova\u0165, ak nie s\u00fa spr\u00e1vne nakonfigurovan\u00e9. Z t\u00fdchto d\u00f4vodov je d\u00f4le\u017eit\u00e1 spr\u00e1vna mont\u00e1\u017e.

\u010eal\u0161ou d\u00f4le\u017eitou vecou, \u200b\u200bktor\u00fa treba zv\u00e1\u017ei\u0165, je materi\u00e1l z\u00e1vitovky. Niektor\u00e9 z\u00e1vitovkov\u00e9 prevody maj\u00fa mosadzn\u00e9 koles\u00e1, ktor\u00e9 m\u00f4\u017eu sp\u00f4sobi\u0165 kor\u00f3ziu v z\u00e1vitovke. Okrem toho sa na mosadznom kolese aktivuje s\u00edrovo-fosforov\u00fd EP olej pre zariadenia. Tieto zdroje m\u00f4\u017eu vies\u0165 k v\u00fdrazn\u00e9mu zn\u00ed\u017eeniu za\u0165a\u017eite\u013enosti. Z\u00e1vitovkov\u00e9 prevody by sa mali nasadi\u0165 s vysoko kvalitn\u00fdm mazivom, aby sa t\u00fdmto probl\u00e9mom predi\u0161lo. Je tie\u017e potrebn\u00e9 zvoli\u0165 materi\u00e1l s vysokou viskozitou a n\u00edzkym tren\u00edm.

Axi\u00e1lny rozstup z\u00e1vitovkov\u00e9ho zariadenia sa vypo\u010d\u00edta pomocou menovitej stredovej vzdialenosti a doplnkov\u00e9ho prvku, konzistentn\u00e9ho. Stredn\u00e1 d\u013a\u017eka je d\u013a\u017eka od stredu ozuben\u00e9ho kolesa k z\u00e1vitovkov\u00e9mu kolesu. Rozstup z\u00e1vitovkov\u00e9ho kolesa sa naz\u00fdva aj rozstup z\u00e1vitovky. Pri v\u00fdpo\u010dte axi\u00e1lneho rozstupu PX pre zariadenie 22 sa ber\u00fa do \u00favahy rozmer a priemer rozstupu.
Axi\u00e1lny rozstup alebo priamy uhol z\u00e1vitovkov\u00e9ho zariadenia ur\u010duje jeho v\u00fdkon. \u010c\u00edm v\u00e4\u010d\u0161\u00ed je vodiaci uhol, t\u00fdm menej je prevodov\u00fd stupe\u0148 produkt\u00edvny.
