Li-bearings tse fapaneng li na le litšobotsi tse fapaneng 'me li loketse maemo a fapaneng a ts'ebeliso ea lisebelisoa tse fapaneng tsa mochini. Basebeletsi ba khetho ba lokela ho khetha mohlala o loketseng oa ho jara ho tsoa ho baetsi ba mefuta e fapaneng ea ho jara le mefuta e mengata ea ho jara.

1. Khetha mohlala oa ho beha ho ea ka sebaka le boemo ba thepa ea mochine e sebelisoang ke ho beha:

Ka kakaretso re sebelisa bolodiberingbakeng sa li-shafts tse nyenyane, le li-roller bearings bakeng sa li-shafts tse kholo. Haeba bophara ba bering bo lekanyelitsoe, ka kakaretso re sebelisa li-bearings tsa nale, li-bearings tsa bolo tse khanyang kapa li-roller bearings; ha ho beleha ho lekanyelitsoe karolong ea axial ea thepa, letoto le moqotetsane kapa la ultra-moqotetsane la libere tsa bolo kapa li-roller bearings.

2. Khetha mohlala oa ho jara ho ea ka mojaro. Moroalo e lokela ho ba ntho ea bohlokoa ka ho fetisisa e lokelang ho nahanoa ha u khetha li-bearings:

Li-roller bearings li ka mamella meroalo e batlang e le kholo, ha li-ball bear li batla li le nyane. Li-bearings tse entsoeng ka tšepe ea carburized li ka mamella meroalo ea ho thothomela le ho sisinyeha. Ha ho hlokahala hore ho be le meroalo e mebe feela, re ka khetha li-bearings tsa "thrust ball", li-cylindrical roller bearings kapa li-bearings tsa nale. Ha mojaro oa axial o batla o le monyane, re ka khetha ho beha bolo ea thrust; ha boima ba axial bo batla bo le boholo, hangata ho sebelisoa "thrust roller bear". Ha li-bearing bearings ka bobeli li axial le radial, hangata re sebelisa li-angular contact ball bearings kapa tapered roller bearings.

3. Ho ea ka litšoaneleho tsa ho ikamahanya le li-bearing, khetha mohlala oa ho beha:

Ha axis ea shaft e sa ts'oane le axis ea setulo se behang, kapa ho le bonolo ho kobeha kapa ho khopama tlas'a khatello, bolo e ikamahanyang le eona kapa roller e ikamahanyang le eona e nang le ts'ebetso e ntle ea ho ikamahanya le eona, le eona. bolo ea ka ntle e ka khethoa. Mofuta ona oa ho jara o ka etsa bonnete ba mosebetsi o tloaelehileng ha shaft e kheloha hanyenyane kapa e kobehile. Melemo le likotsi tsa ts'ebetso ea ho ikamahanya le bering li amana le ho se khonehe ha eona. Ha boleng bo le boholo, bo betere ts'ebetso ea ho ikamahanya le maemo.

4. ho ea ka boima ba ho beha, khetha mohlala oa ho beha:

The deformation elastic ea rollingdiberingha e kholo ebile e ka hlokomolohuoa lisebelisoa tse ngata tsa mochini, empa lisebelisoa tse ling tsa mochini, joalo ka li-spindle tsa sesebelisoa sa mochini, ho satalla ke ntlha ea bohlokoa.
Ka kakaretso re sebelisa cylindrical roller bearings kapa tapered roller bearings bakeng sa lisebelisoa tsa mochini tsa spindle. Hobane mefuta ena e 'meli ea li-bearings e amana le ntlha ha e le tlas'a mojaro, ho thatafala hoa fokola.
Ntle le moo, li-bearings tse fapaneng li ka sebelisa preload ho eketsa boima ba ho jara. Joalo ka li-angular ball bearings le li-bearings tsa tapered roller, e le ho ntlafatsa ts'ebetso ea ts'ehetso, matla a itseng a axial a atisa ho eketsoa esale pele nakong ea kopano ho etsa hore ba thibane. E hatisoa ka ho khetheha mona: matla a ho laela pele a ke ke a ba maholo haholo. Ho seng joalo, likhohlano tsa ho beha li ka 'na tsa eketseha, ho phahama ha mocheso ho tla eketseha,' me bophelo ba tšebeletso ea ho jara bo tla be bo le kotsing.

5. ho ea ka lebelo la ho jara, khetha mohlala oa ho beha:

Ka kakaretso, li-angular contact bearings le li-cylindrical roller bearings li loketse ho sebelisoa libakeng tsa mosebetsi tse potlakileng; li-bearings tsa tapered roller li ka sebelisoa libakeng tsa mosebetsi tse lebelo le tlase. Li-thrust ball bearings li na le lebelo le tlase mme li loketse libaka tse nang le lebelo le tlase.

Bakeng sa mofuta o ts'oanang oa ho jara, tlhaloso e nyane, e phahamisa lebelo le lumellehang la ho potoloha. Ha u khetha mohlala oa ho beha, ela hloko lebelo la sebele le ka tlaase ho lebelo la moeli.
