Izinto zokuthwala kanye nokusebenza

I-ferrule kanye ne-rolling element ye-rolling bearing zicindezelwa ngokuphindaphindiwe ngokucindezela okuphezulu kokuthintana ngenkathi zenza ukuxhumana okugoqayo ngokushelela. I-retainer ixhumana ngokushelelayo nohlangothi olulodwa lwe-ferrule kanye ne-rolling element, noma uhlangothi olulodwa lwayo, futhi ithola amandla okucindezela kanye nokufinyela ohlangothini olulodwa. Ngakho-ke, ulwazi, ukusebenza, kanye nezidingo ezibalulekile ze-ferrule ye-bearing, i-rolling element kanye ne-cage yilezi ezilandelayo.

1. Ukusebenza okuceliwe yidatha ye-ferrule kanye ne-rolling element: amandla okukhathala okugoqayo, ubulukhuni obuphezulu, ukumelana nokuguguleka okuphezulu
2. Ukusebenza okuceliwe yidatha yerakhi yokulungisa: ukuzinza okuhle kobukhulu, amandla aphezulu omshini
3. Ngaphezu kwalokho, idinga ukucutshungulwa. Kuye ngokusetshenziswa kwayo, kuyadingeka futhi ukuthi ibe nokumelana okuhle nokushaqeka, ukumelana nokushisa kanye nokumelana nokugqwala.
4. Ulwazi ngama-ferrule nezinto ezigoqayo: ama-ferrule nezinto ezigoqayo ngokuvamile zenziwe ngensimbi ethwala i-chromium enekhabhoni ephezulu. Iningi lama-bearing lisebenzisa i-SUJ2 ngensimbi ye-JIS. Ama-bearing amakhulu asebenzisa i-SUJ3.

Ukwakheka kwamakhemikhali kwe-SUJ2 kuye kwalinganiswa njengento yokuthwala emazweni ahlukahlukene emhlabeni jikelele. Isibonelo, uhlobo olufanayo lwensimbi njenge-AISL52100 (USA), DIN100Cr6 (West Germany), BS535a99 (UK).
Ngaphezu kwalokho, uma kwenzeka ukumelana nokushayisana, insimbi ye-chrome, insimbi ye-chrome molybdenum, insimbi ye-nickel chrome molybdenum, kanye nokuqina kwe-carbon kusetshenziswa njengedatha yokuthwala ukwenza insimbi ibe nesendlalelo sokuthambisa kusukela ekubukekeni kuya ekujuleni okufanele. Ibhere elifakwe i-carburing elinobubanzi obufanele bokuthambisa, isakhiwo esihle, ubulukhuni obufanele kanye nobunzima obuphakathi linokumelana okuhle kakhulu nokushayisana uma kuqhathaniswa nensimbi ephethe ibhere, kanye nokwakheka kwamakhemikhali kwensimbi ephethe i-carburing ngayinye. I-NSK isebenzise i-vacuum degassing, ngakho-ke idatha esetshenzisiwe ihlanzekile kakhulu, i-oxygen encane futhi ikhwalithi inhle. Ngakho-ke, kuthathwe ikhambi elifanele lokushisa ukuze kuthuthukiswe kakhulu impilo yokukhathala kwebhere.
Ngaphezu kwamazinga ensimbi ashiwo ngenhla, kusetshenziswa insimbi yesivinini esiphezulu ekwazi ukumelana nokushisa kanye nensimbi engagqwali ekwazi ukumelana nokugqwala kuye ngokusetshenziswa okuthile.
