Uma kukhulunywa ngezingxenye zemishini zeimoto engasebenzi kahle yesigaba ezintathu, ama-bearings abaluleke kakhulu ekwenzeni kube lula ukunyakaza nokusekela imithwalo. Izinhlobo ezimbili eziyinhloko zama-bearings ama-rolling bearings nama-plain bearings, ngalinye linezici ezihlukile ezithinta ukusebenza kwawo ezinhlobonhlobo zezicelo. Lesi sihloko sinikeza ukuhlaziywa okuqhathanisayo kwamapharamitha amaningana abalulekile alezi zinhlobo ezimbili zama-bearings. Kuzoba usizo kumakhasimende ukukhetha uhlobo lwemoto kagesi oluhambisana nezidingo zawo.
A. Ukuqhathaniswa kwesakhiwo kanye nemodi yokunyakaza
Ama-rolling bearings aqukethe izinto ezigoqayo ezifana namabhola noma ama-roller anciphisa ukungqubuzana ngokugoqa phakathi komjaho wangaphakathi nowangaphandle. Ngokuphambene nalokho, ama-plain bearings asebenza ngesimiso sokuxhumana ubuso nobuso, ngefilimu yokugcoba evumela ukunyakaza okushelelayo. Lo mehluko oyisisekelo emaphethini okunyakaza uthinta kakhulu ukwakheka kwawo kanye nokusetshenziswa kwawo.
B. Ukuqhathaniswa kwamandla okuthwala umthwalo
Ama-rolling bearings ngokuvamile anomthamo omkhulu wokuthwala umthwalo ngenxa yokuthi umthwalo usatshalaliswa phezu kwezinto eziningi ezigoqayo. Ama-plain bearings, yize ekwazi ukusekela imithwalo esindayo, angase abe namazinga aphezulu okuguguleka ngaphansi kwezimo ezifanayo, okwenza angafaneleki kangako ukusetshenziswa kwemithwalo ephezulu.
C. Ukuqhathaniswa kwe-coefficient yokungqubuzana kanye nokumelana kokuqala kokungqubuzana
Ama-rolling bearings ngokuvamile abonisa i-coefficient ephansi yokungqubuzana, ngaleyo ndlela kunciphisa ukulahlekelwa kwamandla ngesikhathi sokusebenza. Ngokuphambene nalokho, ama-sliding bearings angase abe nokumelana okuphezulu kokungqubuzana kokuqala, okungaholela ekusetshenzisweni kwamandla okwandisiwe ngesikhathi sokuqala.
D. Kusebenza ekuqhathaniseni isivinini sokugijima
Ama-rolling bearings aklanyelwe isivinini esiphezulu sokusebenza, okwenza abe mahle kakhulu ekusetshenzisweni okufana nama-motor kagesi nama-turbine. Kodwa-ke, ama-plain bearings afaneleka kangcono ekusetshenzisweni kwesivinini esiphansi, okunciphisa ingozi yokushisa ngokweqile.
E. Ukuqhathaniswa kokulahlekelwa amandla
Ngenxa yokungqubuzana okuphansi, ama-rolling bearings ngokuvamile abangela ukulahlekelwa kwamandla okuncane kune-plain bearings, ngaleyo ndlela kwandisa ukusebenza kahle kwesistimu iyonke.
F. Ukuqhathaniswa kwempilo yenkonzo
Ama-rolling bearings ngokuvamile aphila isikhathi eside ngenxa yokwakheka kwawo ukuze kuncishiswe ukuguguleka. Ama-plain bearings angadinga ukulungiswa kanye nokushintshwa njalo, ikakhulukazi ngaphansi kwezimo zomthwalo omkhulu.
G. Ukuqhathaniswa kokunemba kokujikeleza
Ama-rolling bearings anikeza ukunemba okuphezulu kokujikeleza, okwenza athandwe kakhulu ekusetshenzisweni okunembile, kuyilapho ama-plain bearings engase alethe ukwehluka okwengeziwe ekusebenzeni kokujikeleza.
Ukukhetha phakathi kwama-rolling bearings nama-sliding bearings kuncike ezidingweni ezithile zohlelo lokusebenza, okuhlanganisa umthamo womthwalo, isivinini, kanye nokunakekelwa. Njengomholi ekukhiqizweni kwezimoto, iWolong ihlomisa i-Ukuthwala kweShayinakanye nezinye izinhlobo ezishisayo zomhlaba wonke ezifanaibhereyi ye-SKF, ibhereyi ye-FAG, ibhereyi ye-NSKnjalo njalo. Ukuqonda lokhu kwahlukana kubalulekile ukuze kuthuthukiswe ukusebenza kwezinhlelo zemishini.
