Krok 1. Vybalenie a kontrola pred in\u0161tal\u00e1ciou<\/h2>\n

Pred za\u010dat\u00edm ak\u00fdchko\u013evek mechanick\u00fdch pr\u00e1c motor d\u00f4kladne skontrolujte. Po\u0161kodenie po\u010das prepravy je be\u017en\u00e9 a mus\u00ed sa identifikova\u0165 pred in\u0161tal\u00e1ciou, nie a\u017e po zapojen\u00ed motora do ovl\u00e1dacieho panela a pripojen\u00ed k poh\u00e1\u0148an\u00e9mu stroju.<\/p>\n

Vizu\u00e1lna vonkaj\u0161ia kontrola<\/div>\n

Skontrolujte r\u00e1m, koncov\u00e9 \u0161t\u00edty, kryt ventil\u00e1tora, svorkovnicu a pred\u013a\u017eenie hriade\u013ea, \u010di nie s\u00fa prasknut\u00e9, prelia\u010diny alebo po\u0161koden\u00e9 n\u00e1razom.

\n
Overenie typov\u00e9ho \u0161t\u00edtku<\/div>\n

Kontrola hriade\u013ea a dr\u00e1\u017eky pre pero<\/div>\n

Skontrolujte priemer a d\u013a\u017eku pred\u013a\u017eenia hriade\u013ea oproti rozmerom otvoru spojky alebo ozuben\u00e9ho kolesa.

Nes\u00faosos\u0165 hriade\u013ea medzi motorom a poh\u00e1\u0148an\u00fdm strojom je hlavnou pr\u00ed\u010dinou pred\u010dasn\u00e9ho zlyhania lo\u017e\u00edsk, opotrebovania spojky a nadmern\u00fdch vibr\u00e1ci\u00ed v priamo spriahnut\u00fdch motorov\u00fdch pohonoch.

Je potrebn\u00e9 opravi\u0165 dva typy nes\u00faososti:<\/p>\n

\n
\n
Rovnobe\u017en\u00e9 (odsaden\u00e9) vych\u00fdlenie<\/div>\n

Osi hriade\u013eov s\u00fa rovnobe\u017en\u00e9, ale posunut\u00e9 v radi\u00e1lnom smere. Meria sa ako rozdiel medzery medzi polovicami spojky v poloh\u00e1ch hore-dole alebo \u013eavo-prav\u00e1 pomocou \u00fachylkomera ot\u00e1\u010dan\u00e9ho okolo spojky. Maxim\u00e1lne povolen\u00e9 rovnobe\u017en\u00e9 posunutie pre pru\u017en\u00e9 spojky: typicky 0,05 a\u017e 0,10 mm pre ve\u013ekosti r\u00e1mu motora do 200, 0,10 a\u017e 0,15 mm pre r\u00e1m 250 a vy\u0161\u0161ie.<\/p>\n

Oprava: zdvihnite alebo spustite motor pomocou podlo\u017eiek; posu\u0148te motor bo\u010dne na dr\u00e1\u017ekovan\u00fdch mont\u00e1\u017enych otvoroch<\/div>\n<\/div>\n
\n
Uhlov\u00e9 vych\u00fdlenie<\/div>\n

Osi hriade\u013eov sa pret\u00ednaj\u00fa pod uhlom, nie s\u00fa koline\u00e1rne.
