Li-bearing tse mocheso o phahameng

Ho Bearing ka Mocheso o Phahameng ke Eng?

Seo ho thoeng ke bearing ea mocheso o phahameng se bolela hore mocheso o sebetsang o phahame ho feta mocheso oa bearing e tloaelehileng, 'me bearing e sebelisoang mochesong o akaretsang oa mosebetsi o fetang 150 degrees.° e bitsoa bearing ea mocheso o phahameng.

 

Litšobotsi tsa li-bearing tsa mocheso o phahameng:

 

1. Setlolo sa bophelo bohle, ha ho mafura a eketsoang nakong ea tšebeliso.

 

2. E theko e tlase, boleng bo phahame ka makhetlo a mangata ho feta ba li-bearing tse tloaelehileng.

 

3. E hapile tšepo ea bareki ba rona ka bophelo bo bolelele ba tšebeletso.

 

4. Li-bearing tse nang le mocheso o phahameng li sebelisoa haholo ho tšepe, li-oven, khalase, liontong tsa ho phatloha, lisebelisoa tsa ho penta le mechini e meng tlas'a ts'ebetso ea mocheso o phahameng.

 

Li-bearing tse nang le mocheso o phahameng li sebelisoa haholo-holo lienjineng tsa jete tsa lifofane, liturbine tsa khase, litsamaisong tsa reactor ea nyutlelie, li-disc tsa tungsten tsa tube ea X-ray, likoloi tse lebelo le phahameng, lirokete le lifofa-sebakeng.

 

Ho kenya dibering tse nang le mocheso o phahameng

Ho phaella moo, haeba kgatello e sebediswa lehlakoreng le leng la lesale (jwalo ka lesale le ka ntle), mme lehlakore le leng la lesale (jwalo ka lesale le ka hare) le hatellwa ho lona ka karolo e pitikisang, sena hangata se tla baka ho kobeha kapa ho kgohlana hodima bokahodimo bo pitikisang, mme ha se a lokela ho sebediswa, haholoholo haeba bearing e sa arolweng e kentswe hodima shaft le bearing house ka nako e le nngwe.

 

Nakong ea ho futhumatsa le ho kenya bearing, ho hlokahala ho utloisisa maemo a mocheso a bearing ea mocheso o phahameng tlas'a li-bearing tse fapaneng tsa mocheso o phahameng.

 

Ho lekana hali-bearing tse mocheso o phahameng

1. Tšitiso

 

Lesale le ka hare le lesale le ka ntle la karolo e pitikoang le tsitsitse hodima shaft kapa lebokose la bere, mme ha le kentswe, lesale le shaft kapa lebokose la bere ha di na metsamao e amanang le radial, axial le rotational, mme motsamao ona o amanang o tla baka kgohlano, kgohlano ya mafome kapa mapetso a kgohlano hodima bokahodimo ba ho kopana, e le ho baka tshenyo ho bearing, shaft le lebokose la bereing, ebe phofo ya abrasion e kopanngwa le bearing, e leng se etsang hore ho be le tshebetso e mpe, ho futhumatsa kapa ho thothomela ho sa tlwaelehang.

 

Ha e le mokhoa oa ho bea o tsitsitseng, ho molemo ho siea bongata ba tšitiso holim'a lesale le shaft kapa ntlo ea ho bea, 'me ho lekana ho sa fetoheng ho be ho loketseng, e le hore mojaro oa lesale le nang le mabota a masesaane o ajoe ka ho lekana selikalikoeng ntle le ho ama bokhoni ba mojaro oa bea.

 

Leha ho le jwalo, ntle le bothata ba ho hokela le ho theola bearing, e ke ke ya sebediswa maemong ohle ha bearing e arotswe mme e ke ke ya sisinyeha ka lehlakoreng le le leng ha bearing e arotswe ha bearing e sebediswa.

 

2. Khetho ea ho lekana

 

Khetho ea ho lekana hangata e etsoa ho latela melao-motheo e latelang:

 

(1) Ho ya ka tataiso le mofuta wa mojaro o sebetsang hodima bearing le hore na ke lehlakore lefe la masale a ka hare le a kantle a potolohang, mojaro o jarwang ke lesale ka leng o ka arolwa ka mojaro o potolohang, mojaro o sa fetoheng, kapa mojaro o sa fetoheng, lesale le jarang mojaro o potolohang le mojaro o sa fetoheng le lokela ho lekana ka tsela e sa fetoheng (ho lekana ha tshitiso), lesale le jarang mojaro o sa fetoheng le ka nka phetoho e lekanang kapa e nang le matla (ho lekana ha clearance), ha mojaro o jarang o le moholo kapa o jara thothomelo le moroalo o tshosang, tshitiso e tlameha ho eketsoa, ​​ha ho sebediswa shaft e se nang letho, lebokose la bearing le nang le mabota a masesaane kapa alloy e bobebe le lebokose la bearing la polasetiki, Ho boetse ho hlokahala ho eketsa bongata ba tshitiso.

 

(2) Ha ho hlokahala ho boloka ho nepahala ho hoholo ha ho potoloha, ho lokela ho sebelisoa li-bearing tse nepahetseng haholo, 'me ho nepahala ha litekanyo tsa li-shaft le mabokose a bearing ho lokela ho ntlafatsoa, ​​e le ho qoba tšitiso e feteletseng, haeba tšitiso e le kholo haholo, ho nepahala ha jeometri ea lebokose la bearing kapa axle ho ka ama jeometri ea lesale la bearing, ka hona ho senya ho nepahala ha ho potoloha ha bearing, haeba mehele ea ka hare le ea ka ntle ea li-bearing tse sa arohaneng (joalo ka li-bearing tsa bolo ea groove e tebileng) e lekana hantle, joale ho kenngoa ha bearing le ho qhaqhoa ha bearing ho thata haholo, 'me ho molemo ho amohela ho lekana ho matla ka lehlakoreng le leng la lesale la ka ntle.

 

3. Tšebelisano-'moho e khothaletsoa

 

Mabapi le bophara ba shaft le mamello ea boholo ba shaft le ntlo ea bearing moo li-bearing li kenngoeng teng, ISO283 (dimensional tolerances and fits) e se e amohetsoe letotong la metric, kahoo mamello ea ho lekana e khethiloe ho latela bophara ba shaft le mamello ea boholo ba shaft.
