Ho na le mekhoa e 'maloa e tloaelehileng ea ho arola li-bearings

1. Classified ho ea ka mofuta oa rolling behang sebopeho

Bearingsli arotsoe ka tse latelang ho latela litaelo tse fapaneng tsa mojaro kapa li-angles tsa mabitso tseo ba ka li jarang:

1) Li-radial bearings---- haholo-holo e sebelisetsoang ho roala li-bearings tse nang le li-radial loads, tse nang le li-angles tse amanang le mabitso ho tloha ho 0 ho ea ho 45. Ho ea ka lehlakoreng la lebitso la ho kopana, e arotsoe ka: radial contact bearing ------ radial bearing with nominal contact angle of 0: ho kopana ha radial angle ---- radial e nang le angle ea lebitso e kholo ho feta 0 ho isa ho 45.

2)Li-thrust bearings---- haholo-holo e sebelisetsoang ho roala li-axial loads, 'me li-angles tsa tsona tse amanang le tsona li kholo ho feta 45 ho isa ho 90. Ho ea ka li-angles tse fapaneng tsa mabitso, li arotsoe ka: li-axial contact bearings ------ thrust bearings tse nang le ho kopana ka lebitso. li-angles tsa 90: li-bearings tsa thrust angle - li-bearings tse nang le li-angles tse kholo ho feta 45 empa li le ka tlase ho 90.

 

Ho ea ka mofuta oa li-rolling element, li-bearings li arotsoe ka:

1) Li-ball bearings-----rolling elements e le libolo:

2) Lirolara-----rolling elements ke lirolara. Ho ea ka mofuta oa li-roller, li-roller bearings li arotsoe ka:

cylindrical rolara libere-----rolling elements ke cylindrical roller bearings, le karo-karolelano ea bolelele le bophara ba li-roller tsa cylindrical e ka tlaase ho kapa e lekana le 3;

The rola element ea nale rolara behang ---- ke ho beha le rolara nale, 'me karo-karolelano ea bolelele ho bophara ba nale rolara e kholo ho feta 3, empa bophara ke ka tlaase ho kapa lekana le 5mm;

Lirolara tse tapered---- li-rolling elements ke li-bearings tsa li-roller tse tapered; Li-roller bearings-li-rolling elements ke li-bearings tsa li-roller tse chitja.

 

Bearingsli arotsoe ka tse latelang ho latela hore na li ka fetoloa nakong ea mosebetsi:

1) Boima ba sedikadikwe---- tsela ea lebelo e chitja, e ka ikamahanyang le ho kheloha ha angular le ho sisinyeha ha angular pakeng tsa mela ea axial ea litsela tse peli tsa lebelo;

2) Li-bearings tse sa lumellaneng(li-bearings tse thata) ---- li-bearings tse ka hanang ho kheloha ha li-axial angle lipakeng tsa litsela.

 

Bearingsli arotsoe ka tse latelang ho ea ka palo ea lintho tse rolling:

1) Li-bearings tsa mela e le 'ngoe---- li-bearings tse nang le mola oa lintho tse bilikang;

2)Li-bearings tse nang le mela e 'meli---- li-bearings tse nang le mela e 'meli ea lintho tse bilikang;

3)Li-bearings tse nang le mela e mengata---- li-bearings tse nang le mela e fetang e 'meli ea lintho tse bilikang, joalo ka mela e meraro le mela e mene.

 

Bearingsli arotsoe ka tse latelang ho latela hore na likarolo tsa tsona li ka aroloa:

1) Li-bearings tse senyehang---- dibering tse nang le dikarolo tse arohaneng;

2) Li-bearings tse sa arohaneng---- li-bearings tse ke keng tsa aroloa ka mokhoa o ikemetseng ka mehele ka mor'a papali ea ho qetela.

 

Bearingse ka boela ea aroloa ka mefuta e sa tšoaneng ea meralo ho ea ka libopeho tsa tsona (tse kang hore na ho na le groove ea ho tlatsa, hore na ho na le selikalikoe sa ka hare le sa ka ntle le sebopeho sa lesale, sebopeho sa flange, esita le hore na ke lesaka, joalo-joalo).

 

Karohano ho ea ka boholo ba li-bearings tse rollang Li-bearings li arotsoe ka tse latelang ho ea ka bophara ba tsona ba kantle:

(1) Li-bearings tse nyenyane---- li-bearings tse nang le boholo ba bophara ba ka ntle ka tlase ho 26mm;

(2) Li-bearings tse nyenyane---- li-bearings tse nang le bophara ba ka ntle ba lebitso ho tloha ho 28 ho ea ho 55 mm;

(3) Li-bearings tse nyenyane le tse mahareng---- li-bearings tse nang le bophara ba ka ntle ka lebitso ka bophara ba 60-115mm;

(4) Li-bearings tse mahareng le tse kholo---- li-bearings tse nang le bophara ba boholo ba ka ntle ba 120-190mm

(5) Li-bearings tse kholo---- li-bearings tse nang le bophara ba ka ntle ba lebitso ho tloha ho 200 ho ea ho 430mm;

(6) Li-bearings tse kholoanyane---- li-bearings tse nang le bophara ba ka ntle ho tloha ho 440mm kapa mor
