Mokhoa oa ho khetha mofuta oa bere

Ha o kgetha mofuta wa bearing, ho bohlokwa ho ba le kutlwisiso e batsi ya maemo ao bearing e tla sebediswa ho ona.

Khetha mokhoa:

1) Sebaka sa ho kenya bere se ka kenngwa sebakeng sa ho kenya bere sa mofuta wa bere hobane ho tiea le matla a bere di elwa hloko ha ho ralwa sistimi ya bere, kahoo bophara ba bere hangata bo kgethwa pele, ke hore, bophara ba kahare ba bere.

Leha ho le jwalo, di-rolling bearings di tla ka mefuta e fapaneng ya boholo le mefuta, mme mofuta o loketseng ka ho fetisisa wa di-bearings o lokela ho kgethwa ho tsona.

 

2) Boholo, tataiso le mofuta oa mojaro oa mojaro o jarang [bokhoni ba mojaro oa mojaro bo bontšoa ke mojaro oa motheo o lekantsoeng, 'me boleng ba oona bo fumaneha tafoleng ea boholo ba mojaro] Mojaro oa mojaro oa fetoha, joalo ka boholo ba mojaro, hore na ho na le mojaro oa radial feela, hore na mojaro oa axial o lehlakoreng le le leng kapa lehlakoreng le leng, tekanyo ea ho thothomela kapa ho tšoha, jj. Kamora ho nahana ka lintlha tsena, ke nako ea ho khetha mofuta oa mojaro o loketseng ka ho fetisisa.

 

Ka kakaretso, bokgoni ba radial load ba di-bearing tse nang le bore e tshwanang bo eketseha ka tatellano e latelang: di-bearing tsa bolo tse tebileng< di-bearing tsa bolo tse amanang le angular< di-bearing tsa roller tse silindara< di-bearing tsa roller tse tapered< di-bearing tsa roller tse chitja

 

3) Mofuta oa bearing eo lebelo la eona la ho potoloha le ka ikamahanyang le lebelo la ho potoloha la mechini [boleng ba moeli ba lebelo la bearing bo bontšoa ke lebelo le lekanyelitsoeng, 'me boleng ba eona bo fumaneha tafoleng ea boholo ba bearing] Lebelo la ho qetela la bearing ha le nkuoe feela ho tsoa mofuteng oa bearing, empa hape le lekanyelitsoe ho boholo ba bearing, mofuta oa lesaka, boemo ba ho nepahala, maemo a mojaro le mekhoa ea ho tlotsa, jj., kahoo lintlha tsena li tlameha ho nahanoa ha ho khethoa.

 

Bongata ba dibering tse latelang di sebediswa bakeng sa ho potoloha ka lebelo le phahameng:

Li-bearing tsa bolo tse tebileng tsa groove, libere tsa bolo tse hokahaneng le angular, libere tsa rolara tse silindara

 

4) Ho nepahala ha ho potoloha: Mofuta oa bearing o nang le ho nepahala ho hlokahalang ha ho potoloha Spindle ea sesebelisoa sa mochini, turbine ea khase le mochini oa taolo li hloka ho nepahala ho phahameng ha ho potoloha, lebelo le phahameng le khohlano e tlase ka ho latellana, kahoo li-bearing tse nang le ho nepahala ha sehlopha sa 5 kapa ho feta li lokela ho sebelisoa.

 

Hangata ho sebelisoa li-bearing tse latelang:

Li-bearing tsa bolo ea groove e tebileng, dibering tsa bolo ya ho ikopanya tse nang le angular,libere tsa rolara tse silindara

 

5) Mofuta oa bere eo ho tiea ha eona ho fihlelang ho tiea ho hlokahalang bakeng sa ho shafting ka mechine Likarolong tse kang li-spindle tsa lisebelisoa tsa mochini le lisebelisoa tsa ho fokotsa mohato oa ho qetela oa koloi, hoa hlokahala ho ntlafatsa ho tiea ha bere le ho tiea ha bere.

 

Ho feto-fetoha ha di-roller bearing ho tlase ho feta ha di-ball bearing.

 

Ho kenya mojaro pele (negative clearance) ho bearing ho ka ntlafatsa ho tiea. Mokhoa ona o loketse li-bearing tsa bolo ea ho kopana le li-bearing tsa roller tse tapered.

 

6) Hlahloba ho sekamela ho amanang pakeng tsa lesale le ka hare le lesale le ka ntle la bearing (joalo ka ho kheloha ha shaft ho bakoang ke mojaro, ho nepahala ho fokolang ha shaft le khetla kapa phoso ea ho kenya), 'me u khethe mofuta oa bearing o ka ikamahanyang le maemo a ts'ebeliso. Haeba tšekamelo e amanang ea lesale le ka hare ho lesale le ka ntle e le kholo haholo, bearing e tla senyeha ka lebaka la mojaro o ka hare. Ka hona, mofuta oa bearing o ka mamellang ho sekamela hona o lokela ho khethoa.

 

Ka kakaretso, sekhutlo se dumeletsweng sa ho sekamela (kapa sekhutlo se chitja) se eketsoa ka tatellano e latelang:

Li-bearing tsa li-roller tsa cylindrical, dibering tse nang le dirola tse tenya, dibering tse tebileng tsa bolo ya mokoti (dibering tsa bolo ya ho ikopanya tse nang le di-angle), dibering tse chitja tsa rola (bolo)

 

7) Ha kgafetsa ya kopano le ho qhaqha jwalo ka tlhahlobo ya nako le nako ya ho kenya le ho qhaqha le mokhoa wa kopano le ho qhaqha e le kgafetsa, ho bonolo haholo ho sebedisa di-roller bearings tsa cylindrical, di-roller bearings tsa nale le di-roller bearings tse tapered tse ka arolwang ho lesale le ka hare le lesale le ka ntle.

 

Li-bearing tsa bolo e chitja le li-bearing tsa roller tse chitja tse nang le mokoti o teteaneng li ka kopanngoa le ho qhaqhoa habonolo ka ho sebelisa li-fasteners kapa li-sleeve tsa ho hula.

 

Haeba o batla ho tseba tlhahisoleseling e batsi e amanang le eona, ka kopo ikopanye le rona:
