Ungahlukanisa kanjani phakathi kwama-bearings anejubane eliphansi nama-bearings anejubane eliphezulu?

 

Amabheringi asheshayo aphezulu naphansingokuvamile zibekwe ngesivinini esiqondile kunesivinini esijikelezayo. Ijubane lama-bearings anejubane eliphezulu kumele lifinyelele izidingo zesivinini ezingaphezu kwamamitha angu-60 ngomzuzwana, ngakho-ke ama-bearings amancane angaba amashumi ezinkulungwane zokujikeleza, kodwa awawona ama-bearings anejubane eliphezulu, futhi ama-bearings amakhulu kakhulu abhekwa njengama-bearings anejubane eliphezulu ngamakhulu okujikeleza ngomzuzu, isizathu ukuthi ijubane eliqondile lalawa akamuva likhulu. Phakathi kwama-bearings alula, ama-bearings e-hydrohydrostatic, ama-bearings e-hydrodynamic, ama-bearings e-hydrostatic, kanye nama-bearings e-hydrodynamic konke kufanelekile ekujikelezeni kwejubane eliphezulu.

 

Amabheringi ajikelezayongokuvamile asetshenziselwa izinhlelo zokusebenza ezinejubane eliphansi, kanti ama-plain bearings avame ukusetshenziswa ezinhlelweni zejubane eliphezulu. Njengoba igama lisikisela, kunezibhola kuma-rolling bearings, ayindilinga, ayindilinga, futhi ayindilinga. Ama-plain bearings ngokuvamile angama-bearings. Kunzima ukuhlukanisa phakathi kwama-high speed bearings nama-low speed ngokubukeka, futhi ama-low speed bearings avamile ashibhile futhi ashibhile, kodwa kuneziningi ze-high speed bearings ezisetshenziswa ngaphakathi komshini.

 

Amabheringi asheshayongokuvamile zisetshenziswa ngaphakathi komshini. Ukupholisa nokugcoba ngamafutha okuthwala uketshezi. Uma i-bearing ingasetshenziswa emotweni, awekho amandla amaningi esivinini esiphezulu semoto, i-bearing yesivinini esiphezulu nayo ingapholiswa futhi igcotshwe ngamafutha okuthwala aqinile. Ngokuvamile, ama-bearing esivinini esiphezulu asetshenziswa ngaphakathi komehluko wokudlulisa injini, kuyilapho ama-bearing esivinini esiphansi esetshenziswa ku-chassis njengama-wheel bearing e-half-shaft.

 

Uma kufanele uhlukanise ama-bearings anejubane eliphezulu naphansi ekubukekeni, ungabheka amaphuzu amabili alandelayo:

 

1. Iibhereyini yesivinini esikhuluI-g inokunemba okuphezulu kunebhereyitha yesivinini esiphansi, futhi ubulukhuni bayo bomphezulu buncane. Umehluko obonakalayo ukuthi umphezulu webhereyitha yesivinini esiphezulu ubushelelezi kunowebhereyitha yesivinini esiphansi, kanti igebe phakathi kwendandatho yangaphandle ejikayo kanye nebhereyitha yesivinini esiphezulu yendandatho yangaphakathi lincane, kanti okuphambene nalokho kuyiqiniso ngebhereyitha yesivinini esiphansi.

 

2. Uma kuqhathaniswa nama-bearings anejubane eliphansi, ukunemba kwama-bearings anejubane eliphezulu kuhlukile, futhi ukunemba kwemigwaqo yomjaho kuphakeme kunokwama-bearings anejubane eliphansi.

 

I-rolling bearing ejwayelekile ifanelekela ukujikeleza kwesivinini esiphansi nesiphakathi, uma ukusetshenziswa kwe-rolling bearing ukujikeleza kwesivinini esikhulu kudinga izidingo ezikhethekile, imodeli ingakhethwa ngokufanele ngokuya ngomthwalo osetshenzisiwe nezinye izici.

 

Uma ijubane liphakathi kwamamitha angu-5 no-60 ngomzuzwana, alibhekwa njenge-bearing yesivinini esikhulu, futhi i-bearing ejwayelekile ingahlangabezana nezidingo uma nje ingagcotshwa. Uma usebenzisa ama-bearing anejubane eliphezulu kwezinye izikhathi ezikhethekile, njengama-bearing ajikelezayo anejubane eliphezulu asetshenziswa kumathuluzi omshini wokusika ngesivinini esikhulu noma amathuluzi omshini wokugaya ngokunemba, ungasebenzisa nama-bearing akhethekile afana nalawaamabheringi e-ceramic, eamandla kagesi, kanye nama-magnetic bearings
