Ho na le lintlha tse 'maloa tsa ho khetha mofuta oa rolling bearing

Ho jara e le karolo ea mantlha ea lisebelisoa tsa mochini, ts'ebetsong ea ts'ebetso e phetha karolo ea bohlokoa, kahoo rona bakeng sa khetho ea mofuta oa ho roala ke ntlha ea bohlokoa haholo,CWL e behange tla u bolella kamoo re ka khonang ho fumana mofuta o loketseng ka ho fetisisa oa ho beha ha re khetha mofuta oa ho roala, ka likarolo tsena ho khetha mofuta oa ho roala.

 

Ho khetha mofuta o nepahetseng oarolling bear, sheba lintlha tsena tse kholo:

1. Maemo a mojaro

Boholo, tataiso le tlhaho ea mojaro holim'a ho jara ke motheo o ka sehloohong oa ho khetha mofuta oa ho jara. Haeba mojaro o le monyane ebile o tsitsitse, li-ball bearings ke boikhethelo; Ha mojaro o le moholo 'me ho na le tšusumetso, ho eletsoa ho khetha li-roller bearings; Haeba ho beleha ho itšetlehile feela ka mojaro oa radial, khetha radial contact ball bearing kapa cylindrical roller bearing; Ha feela mojaro oa axial o amoheloa, ho lokela ho khethoa sebaka sa ho phunya; Ha ho beoa ho tlas'a meroalo ea radial le axial, li-angular contact bearings li khethoa. E kholoanyane mojaro oa axial, e kholoanyane ho lokela ho khethoa angle ea ho kopana, 'me haeba ho hlokahala, ho ka khethoa motsoako oa radial bearing le thrust bear. Hoa lokela ho hlokomeloa hore li-thrust bearings li ke ke tsa mamella meroalo ea mahlaseli, 'me li-cylindrical roller bearings li ke ke tsa mamella meroalo ea axial.

 

2. Lebelo la ho jara

Haeba boholo le ho nepahala ha ho beleha ho tšoana, lebelo la ho qetela la bolo ea maoto le phahame ho feta la rolara, kahoo ha lebelo le le holimo le ho nepahala ha ho potoloha ho hlokahalang ho ba holimo, ho lokela ho khethoa sebaka sa bolo. .

 

Li-thrust bearingsho ba le lebelo le fokolang le fokolang. Ha lebelo la ho sebetsa le phahame 'me mojaro oa axial o se moholo, li-bearings tsa li-angular ball kapa li-deep groove ball bearings li ka sebelisoa. Bakeng sa li-bearings tse pota-potileng ka lebelo le phahameng, e le ho fokotsa matla a centrifugal a hlahisoang ke likarolo tse pota-potileng ka ntle ho lesale la peiso, ho eletsoa ho khetha li-bearings tse nang le bophara bo bonyenyane ba ka ntle le bophara ba likarolo tse pota-potileng. Ka kakaretso, ho lokela ho netefatsoa hore ho bea ho sebetsa ka tlase ho lebelo la moeli. Haeba lebelo la ho sebetsa le feta lebelo le lekanyelitsoeng la ho jara, litlhoko li ka finyelloa ka ho eketsa boemo ba mamello ea ho jara le ho eketsa ka mokhoa o nepahetseng tumello ea eona ea mahlaseli.

 

3. Ts'ebetso ea ho ikamahanya

Lehlakore la ho fokotsa pakeng tsa axis ea lesale la ka hare le le ka ntle la ho jara le lokela ho laoloa ka har'a tekanyo ea moeli, ho seng joalo mojaro o eketsehileng oa ho jara o tla eketseha 'me bophelo ba oona ba tšebeletso bo fokotsehe. Bakeng sa tsamaiso ea shaft e nang le ho satalla ho fokolang kapa ho se nepahale hantle ha ho kengoa, lehlakoreng la ho kheloha pakeng tsa axis ea lesale la ka hare le le ka ntle la ho jara le leholo, 'me ho eletsoa ho khetha bere e ikemetseng. Joalo kaho ikamahanya le libolo(sehlopha sa 1), li-rolara tse ikamahanyang le tsona (sehlopha sa 2), joalo-joalo.

 

4. Sebaka se lumelletsoeng

Ha boholo ba axial bo lekanyelitsoe, ho eletsoa ho khetha li-bearings tse moqotetsane kapa tse eketsehileng. Ha boholo ba radial bo lekanyelitsoe, ho eletsoa hore u khethe bere e nang le likarolo tse nyane tsa rolling. Haeba boholo ba radial bo nyane mme boima ba radial bo le boholo,dibering rolara ya nalee ka khethoa.

 

5. Kopano le ts'ebetso ea tokiso

Masale a ka hare le kantle adibering rolara tapered(Sehlopha sa 3) lecylindrical rolara libere(Sehlopha sa N) se ka aroloa, ho etsa hore ho be bonolo ho bokella le ho qhaqha.

 

6. Moruo

Tabeng ea ho finyella litlhoko tsa tšebeliso, ho jara litšenyehelo tse tlaase ho lokela ho khethoa ka hohle kamoo ho ka khonehang. Ka kakaretso, theko ea libering tsa bolo e tlase ho feta ea li-roller bearings. Ha sehlopha sa ho nepahala se phahame, theko ea eona e phahame.

Haeba ho se na litlhoko tse khethehileng, li-bearings tse tloaelehileng tse nepahetseng li lokela ho khethoa ka hohle kamoo ho ka khonehang, 'me feela ha ho e-na le litlhoko tse phahameng bakeng sa ho nepahala ha potoloho, li-bearings tse phahameng tse nepahetseng li lokela ho khethoa.

 

Rolling bearing e boetse e le karolo e nepahetseng ea mochini, mefuta ea eona ea rolling le eona e mengata haholo, mefuta e mengata ea likopo e boetse e na le bophara bo bongata, empa re ka khetha mofuta o loketseng oa ho roala ho ea ka maemo le litlhoko tse itseng, e le hore re ka ntlafatsa hamolemo. ts'ebetso ea tlhahiso ea lisebelisoa tsa mochini.
