Amabheringi esitimela - izici zamabheringi e-axle kanye nezicelo

Ngokuthuthuka komphakathi, imboni yokukhiqiza imishini yesitimela iyaqhubeka nokuthuthuka, uma kuqhathaniswa nobuchwepheshe bokukhiqiza amabhereli esitimela buqhubeka nokuthuthuka, lapho indima eyinhloko yebhereli eligoqekayo kubhokisi lamagiya iwukukwazi ukudlulisa i-torque yokukhipha ngokuzinzile lapho isitimela sisebenza ngesivinini esikhulu, okusho ukuthi kumele sithwale umthwalo womthelela ongashintsha endaweni eyinkimbinkimbi. Izinhlobo eziyinhloko zamabhereli amabhereli athambile, amabhereli okuxhumana anamaphuzu amane kanye namabhereli ajikelezayo ayindilinga. Amalungiselelo amabhereli ayahlukahluka kuye ngomklamo kanye nezimo zokusebenza kwebhokisi lamagiya.

 

Ama-gearbox e-axle

Ukusebenza okuyinhloko kwama-bearings kuma-gearbox yilokhu:

Isivinini esiphezulu; Ithwala umthwalo ophezulu; Ukumelana nokudlidliza nokushaqeka; Ukumelana nokushisa okuphezulu.

Ukukhetha i-bearing kunqunywa ngokobukhulu besizinda esifanele sebhokisi legiya, kucatshangelwa izici zokusetshenziswa ezingenhla, futhi ngokuvamile kudinga impilo ebalwe engaphezu kwamakhilomitha ayizigidi ezimbili.

 

Izinhlelo zokuthwala ibhokisi legiya le-axle

1. Ama-roller bearings athambile

Ama-roller bearings athambile ahlukaniswa, futhi i-inner ring roller cage assembly kanye ne-outer ring assembly ingahlanganiswa ngokwehlukana. Ukuxhumana okuqondile okulungisiwe phakathi kwezinto ezigoqayo kanye nomgwaqo wokugijima kugwema ukucindezeleka komphetho. Ama-roller bearings athambile angamelana nemithwalo ephezulu ye-radial kanye ne-axial. Ngenxa yokuthi la ma-bearings angamelana namandla e-axial ohlangothini olulodwa, adinga ukusetshenziswa ekuhlanganisweni. Lolu hlobo lwe-bearings lusetshenziswa kuma-gearbox kanye nama-axle box.

 

2. Ukuthwala kokuxhumana okunamaphuzu amane

Ama-bearings ebhola lokuxhumana anamaphuzu amane angama-bearings ebhola lokuxhumana angama-angular. Angamelana nemithwalo ye-axial kuzo zombili izinhlangothi futhi ngokuvamile ahlanganiswa nama-bearings e-cylindrical roller ukuze amelane namandla e-radial, ngokulingana kwe-radial clearance. Isakhiwo esihlukanisiwe sendandatho yangaphakathi siyivumela ukuthi ihlanganise amabhola ensimbi engeziwe. Lawa ma-bearings asetshenziswa kuma-gearbox.

 

3.Ama-roller bearings e-cylindrical

Ama-roller bearings angumugqa owodwa asetshenziswa kakhulu kuma-railway bearings kunamanye ama-bearings ngoba indandatho yangaphakathi ingahlukaniswa ne-assembly eyakhiwe yi-outer ring, ama-rollers kanye ne-cage, okuwusizo kakhulu ekufakweni, ekuhlukaniseni, ekugcinweni nasekuhlolweni kwe-bearings. Ama-roller bearings angu-cylindrical ayakwazi ukumelana namandla aphezulu e-radial, futhi ukuxhumana okuqondile okuqondile phakathi kwezinto ezigoqayo kanye nomzila wokugijima kususa ukucindezeleka konqenqema, okwandisa ukuthembeka kwezicelo zokuthwala. Ukuhlanganiswa kwama-roller bearings angu-NJ kanye ne-NUP cylindrical kungamelana namandla aqinile e-axial. Lawa ma-bearings asetshenziswa kuma-traction motors, ama-gearbox, kanye nama-wheelset hollow shaft drive.

 

4. Amabheringi afakwe ugesi

Ngaphansi kwezimo zokusebenza ezimbi noma ezikhethekile, i-shaft bearing kanye ne-motor bearing kungase konakale ngenxa ye-voltage eyengeziwe. Nakuba inqubo yokukhiqiza yemoto iphelele, akunakwenzeka ukugwema ngokuphelele umehluko ongaba khona phakathi kwe-rotor ne-stator ngenxa ye-electromagnetic asymmetry, ngakho-ke ugesi udlula ku-bearing bese wakha isekethe elivaliwe. Ukuze ugweme lesi simo esingenhla, faka i-oxide ceramic coating ebusweni bendandatho yangaphandle ye-bearing ukuze uvimbele i-voltage okungenani i-1000V, futhi uvikele i-bearing ekwehlulekeni kwe-bearing ngenxa yokuguguleka kukagesi okubangelwa yi-voltage eyengeziwe.
