Ho na le lintlha tse 6 tseo u lokelang ho li nahana ha u khetha li-bearings bakeng sa lisebelisoa tsa sehatsetsing

 

Mefuta eohle ea li-rolling bearing e na le litšobotsi tse fapaneng 'me e loketse linyeoe tse fapaneng tsa ts'ebeliso ea mechini e fapaneng. Maemong a tloaelehileng,li-bearing tsa ho sutumelletsa le li-bearing tsa ho ikopanya tse ka lehlakoreng le lengli khethoa ha ho jara meroalo e sutumelletsoang;

 

Li-bearing tsa bolohangata li sebelisoa bakeng sa lits'ebetso tse potlakileng haholo, 'me li-roller bearing li sebelisoa bakeng sa meroalo e boima ea radial.

 

1. Sebaka le sebaka sa mechini e sebelisoang kebearing

 

Moralong oa mechini, boholo ba shaft hangata bo khethoa pele, ebe bearing e bilikanang e khethoa ho latela boholo ba shaft. Li-bearing tsa bolo hangata li sebelisoa bakeng sa li-shaft tse nyane le li-bearing tsa li-roller bakeng sa li-shaft tse kholo. Leha ho le joalo, ha bearing e lekanyelitsoe ka lehlakoreng la bophara ba mochini,libere tsa rolara ea nale, dibering tsa bolo kapa di-roller tsa letoto la mabone a eketsehileng le mabone a mangata di a kgethwa; Ha boemo ba axial ba bearing ka hara mochini bo lekanyeditswe, letoto le lesesane kapa le lesesane haholo la dibering tsa bolo kapa di-roller di a fumaneha.

 

2. Boholo, tataiso le mofuta oa mojaro holim'a bearing

 

Mojaro ke ntlha ea bohlokoa ka ho fetisisa khethong ea li-bearing. Li-bearing tsa li-roller li sebelisetsoa ho mamella meroalo e boima, li-bearing tsa bolo li sebelisetsoa ho mamella meroalo e bobebe kapa e itekanetseng, 'me li-bearing tse entsoeng ka tšepe e nang le khabone kapa tse timisitsoeng ke bainite li etselitsoe ho mamella meroalo ea ho tšoha le ho thothomela.

 

Mabapi le tataiso ea ts'ebetso ea mojaro, ha ho jere meroalo e hloekileng ea radial, ho ka khethoa li-bearing tsa bolo tse tebileng, li-bearing tsa roller tse silindara kapa li-bearing tsa roller tsa nale. Ha ho jere meroalo e menyenyane e hloekileng ea axial, ho ka khethoa li-bearing tsa bolo tse phutholohileng; Li-bearing tsa roller tse phutholohileng lia fumaneha bakeng sa meroalo e meholo e hloekileng ea axial. Ha bearing e le tlas'a mojaro o kopaneng oa radial le axial, li-bearing tsa bolo tse hokahaneng tsa angular kapa li-bearing tsa roller tse tapered.

 

3.Tshebetso ea ho ikamahanya ha bearing

 

Ha mola o bohareng oa shaft o fapane le mola o bohareng oa ntlo ea ho bea, ho na le phoso ea angular, kapa hobane sebaka se pakeng tsa litšehetso tse peli tsa shaft se seholo 'me ho tiea ha shaft ho le honyenyane, ho bonolo ho kobeha kapa ho sekamela tlas'a matla, bolo e iketsang kapa bearing ea roller e iketsang e nang le ts'ebetso e ntle ea ho iketsa le bearing ea bolo e ka ntle li ka khethoa. Li-bearing tsena li lula li sebetsa ka mokhoa o tloaelehileng ha shaft e sekame kapa e kobehile hanyane.

 

Boleng ba ts'ebetso ea ho ikamahanya le bearing bo amana le axiality e fapaneng eo bo e lumellang, 'me ha boleng ba axiality e fapaneng bo le boholo, ts'ebetso ea ho ikamahanya le eona e ba betere.

 

4. Ho tiea ha bearing

 

Ho tiea ha bearing ho bolela bongata ba matla a hlokahalang bakeng sa bearing ho hlahisa phetoho ea yuniti. Ho tenyetseha ha li-bearing tse bilikanang ho honyenyane haholo, 'me ha ho hlokahale ho ho nahana ka mechini e mengata, empa mechining e meng, joalo ka li-spindle tsa lisebelisoa tsa mochini, ho tiea ha bearing ke ntlha ea bohlokoa, 'me li-bearing tse silindara le tse tapered roller ka kakaretso li lokela ho khethoa. Hobane mefuta ena e 'meli ea li-bearing e kopana hantle le tsela ea peiso ha e le tlas'a mojaro, ho tiea ha eona hoa fokola.

 

Ho phaella moo, mefuta yohle ya di-bearings e ka boela ya kenngwa pele ho fihlella sepheo sa ho eketsa ho tiya ha tshehetso. Mohlala,libere tsa bolo tse hokahaneng le angularle li-bearing tse nang le li-roller tse tapered, e le ho thibela ho thothomela ha shaft le ho eketsa ho tiea ha tšehetso, matla a itseng a axial hangata a sebelisoa esale pele nakong ea ho kenngoa ho etsa hore li hatellane. Ho bohlokoa ho hlokomela mona hore bongata ba ho jara pele ha boa lokela ho ba boholo haholo. Ha e le kholo haholo, khohlano ea bearing e tla eketseha, ho phahama ha mocheso ho tla eketseha, 'me bophelo ba tšebeletso ea bearing bo tla ameha.

 

5. Lebelo la ho potoloha ha bearing

 

Mohlala o mong le o mong oa ho bea o na le lebelo la oona la moeli, le khetholloang ke litšobotsi tsa 'mele tse kang boholo, mofuta le sebopeho, lebelo la moeli le bolela lebelo le phahameng ka ho fetisisa la ho sebetsa la ho bea (hangata r/min), ho feta moeli ona ho tla etsa hore mocheso oa ho bea o phahame, setlolo se omelle, esita le ho etsa hore ho bea ho khomarele. Lebelo le hlokahalang bakeng sa ts'ebeliso le thusa ho fumana hore na ke mofuta ofe oa ho bea o lokelang ho sebelisoa. Bahlahisi ba bangata ba ho bea ba fana ka boleng ba lebelo la ho qetela la lihlahisoa tsa bona likhathalogeng tsa lihlahisoa tsa bona, 'me mokhoa o pakile hore ho molemo ho sebetsa boemong bo ka tlase ho 90% ea lebelo le lekanyelitsoeng.

 

Ka kakaretso, nakong ea mosebetsi oa lebelo le phahameng, ho eletsoa ho khetha li-bearing tsa bolo ea deep groove, li-bearing tsa angular contact, le li-bearing tsa cylindrical roller; Ka lebelo le tlase, li-bearing tsa roller tse tapered ke tsa boikhethelo. Lebelo la ho qetela la li-bearing tsa roller tse tapered hangata ke hoo e ka bang 65% ea la li-bearing tsa bolo ea deep groove, 70% ea li-bearing tsa cylindrical roller, le 60% ea li-bearing tsa bolo ea angular contact. Li-bearing tsa bolo ea thrust li na le lebelo le tlase la moeli 'me li ka sebelisoa feela ka lebelo le tlase.

 

6. E loketse ho kenngoa le ho qhaqhoa ha li-bearing

 

Ha ho kgethwa mofuta wa bearing, ho boetse ho hlokahala ho nahana hore na bearing e loketse ho kengwa le ho qhaqhwa, haholo-holo bakeng sa ho kengwa le ho qhaqhwa ha dibearing tse kgolo le tse kgolo haholo. Dibearing tse akaretsang tsa bolo ya ho ikopanya tse kang angular, dibearing tse nang le di-roller tse tapered, dibearing tse nang le di-roller tse nang le di-needle tse nang le mehele ya kantle e ka arolwang di bonolo ho di kenya le ho di qhaqhwa, mme mehele ya tsona ya ka hare le ya kantle e ka kenngwa hodima shaft kapa ka hara bore ya ntlo ka ho latellana. Ho phaella moo, dibearing tse nang le di-roller tse chitja tse nang le bore e tapered le sleeve ya adapter, dibearing tse nang le di-roller tse nang le mela e mmedi le di-roller tse chitja di bonolo ho di kenya le ho di qhaqha.
