1. Ako funguje z\u00e1vitovkov\u00fd prevodov\u00fd mechanizmus<\/h2>\n

Z\u00e1vitovkov\u00fd reduk\u010dn\u00fd prevod sa sklad\u00e1 z dvoch hlavn\u00fdch komponentov: z\u00e1vitovky (\u0161pir\u00e1lov\u00e1 skrutka vyroben\u00e1 z kalenej legovanej ocele) a z\u00e1vitovkov\u00e9ho kolesa (ozuben\u00e9 koleso vyroben\u00e9 z odstredivo liateho bronzu alebo tv\u00e1rnej liatiny, namontovan\u00e9 na v\u00fdstupnom hriadeli pod uhlom 90 stup\u0148ov k z\u00e1vitovkov\u00e9mu hriade\u013eu). Z\u00e1vitovka je priamo spojen\u00e1 so vstupn\u00fdm hriade\u013eom poh\u00e1\u0148an\u00fdm motorom alebo je s n\u00edm integrovan\u00e1. Ke\u010f sa z\u00e1vitovka ot\u00e1\u010da, jej \u0161pir\u00e1lov\u00e9 z\u00e1vity zaberaj\u00fa do zubov z\u00e1vitovkov\u00e9ho kolesa, \u010d\u00edm sa vysokor\u00fdchlostn\u00fd rota\u010dn\u00fd pohyb vstupu motora premie\u0148a na pomal\u00fd rota\u010dn\u00fd pohyb v\u00fdstupn\u00e9ho hriade\u013ea v pravom uhle.<\/p>\n

Prevodov\u00fd pomer z\u00e1vitovkov\u00e9ho reduktora je ur\u010den\u00fd po\u010dtom z\u00e1berov na z\u00e1vitovke a po\u010dtom zubov na z\u00e1vitovkovom kolese. Pre z\u00e1vitovku s jedn\u00fdm z\u00e1berom v z\u00e1bere so z\u00e1vitovkov\u00fdm kolesom so 60 zubami je prevodov\u00fd pomer 60:1 \u2013 v\u00fdstupn\u00fd hriade\u013e vykon\u00e1 jednu ot\u00e1\u010dku na ka\u017ed\u00fdch 60 ot\u00e1\u010dok vstupn\u00e9ho hriade\u013ea. \u0160tandardn\u00e9 jednostup\u0148ov\u00e9 prevody v s\u00e9rii korejsk\u00fdch reduk\u010dn\u00fdch prevodov Ever-Power RV\/NMRV sa pohybuj\u00fa od 5:1 do 100:1, pokr\u00fdvaj\u00fac v\u00fdstupn\u00e9 ot\u00e1\u010dky od 29 ot.\/min (100:1 pri vstupn\u00fdch ot\u00e1\u010dkach motora 2 900 ot.\/min) a\u017e do 290 ot.\/min (5:1 pri vstupn\u00fdch ot\u00e1\u010dkach motora 1 450 ot.\/min).<\/p>\n
