Ama-Bearings ayingxenye ebalulekile yemishini yesimanje. Umsebenzi wayo oyinhloko ukusekela umzimba ojikelezayo wemishini, ukunciphisa i-coefficient yokungqubuzana phakathi nokunyakaza kwawo, nokuqinisekisa ukunemba kwawo kokujikeleza.

Ngokwezakhiwo ezihlukene zokungqubuzana kwezinto ezihambayo, ama-bearings angahlukaniswa abe izigaba ezimbili: ama-rolling bearings nama-sliding bearings.

Okuvame ukusetshenziswa kuma-rolling bearings ama-deep groove ball bearings, ama-cylindrical roller bearings nama-thrust ball bearings. Phakathi kwazo, ama-rolling bearings alinganiswe futhi ahlukaniswa ngama-serialized, futhi ngokuvamile akhiwa izingxenye ezine: iringi yangaphandle, iringi yangaphakathi, umzimba ogoqayo kanye nekheji.

Ama-deep groove ball bearingsikakhulukazi ithwala umthwalo we-radial, futhi ingathwala umthwalo we-radial kanye nomthwalo we-axial ngesikhathi esifanayo. Uma ingaphansi komthwalo weradial kuphela, i-engeli yokuxhumana inguziro. Lapho i-deep groove ball bearing ine-radial clearance enkulu, inokusebenza kwe-angular contact bearing futhi ingathwala umthwalo omkhulu we-axial. I-coefficient ye-friction ye-deep groove ball bear incane kakhulu futhi isivinini somkhawulo siphezulu.

Ama-deep groove ball bearings angama-bearings amelela kakhulu futhi asetshenziswa kabanzi. Ilungele ukusebenza ngesivinini esiphezulu ngisho nangaphezulu, futhi ihlala isikhathi eside ngaphandle kokugcinwa njalo. Lolu hlobo lokuthwala lune-coefficient encane yokungqubuzana, isivinini somkhawulo ophezulu, isakhiwo esilula, izindleko zokukhiqiza eziphansi futhi kulula ukufeza ukunemba okuphezulu kokukhiqiza. Ibanga losayizi nefomu liyahlukahluka, futhi lisetshenziswa kumathuluzi anembayo, izinjini ezinomsindo omncane, izimoto, izithuthuthu nemishini evamile nezinye izimboni, futhi ziwuhlobo olusetshenziswa kakhulu lwamabheringi embonini yemishini. Ikakhulukazi ithwala umthwalo we-radial, kodwa futhi ithwala inani elithile lomthwalo we-axial.

Ama-Cylindrical roller bearings, izakhi ezigoqayo zingama-radial rolling bearings of cylindrical rollers. Amarola angama-cylindrical kanye nemigwaqo yomjaho angama-linear contact bearings. Umthamo wokulayisha, ikakhulukazi umthwalo we-radial. Ukungqubuzana phakathi kwesici esigoqayo kanye nombambo lwendandatho kuncane, okulungele ukuzungezisa ngesivinini. Ngokuya ngokuthi iringi inazo yini izimbambo noma cha, ingahlukaniswa ibe ama-bearings omugqa owodwa njenge-NU, NJ, NUP, N, NF, nama-double row bearings afana ne-NNU kanye ne-NN.

Ama-Cylindrical roller bearings ngaphandle kwezimbambo endongeni yangaphakathi noma yangaphandle, izindandatho zangaphakathi nangaphandle zingahamba ngokuhlobene nesiqondiso se-axial, ngakho-ke zingasetshenziswa njengama-bearings okuphela kwamahhala. Ama-roller bearings angama-cylindrical anezimbambo ezimbili ohlangothini olulodwa lwendandatho yangaphakathi nendandatho yangaphandle kanye nolunye uhlangothi lwendandatho lungamelana nezinga elithile lomthwalo we-axial ohlangothini olulodwa. Ngokuvamile, kusetshenziswa ikheji lokunyathela lensimbi, noma kusetshenziswa i-alloy yethusi ephenduka ikheji eliqinile. Nokho, kukhona futhi ingxenye ukusetshenziswa polyamide ukwakha yezinyoni.

Ama-thrust ball bearings aklanyelwe ukumelana nemithwalo ye-thrust ngesikhathi sokusebenza ngesivinini esikhulu, futhi ahlanganisa ama-washer-like ferrules anemisele yomjaho wokugingqika ibhola. Njengoba i-ferrule isesimweni se-cushion yesihlalo, i-thrust ball bearing ihlukaniswe yaba izinhlobo ezimbili: uhlobo lomcamelo wesihlalo esiyisicaba kanye nohlobo lwesihlalo esiyisiyingi esiziqondanisa ngokwakho. Ngaphezu kwalokho, lokhu kuthwala kungakwazi ukumelana nemithwalo ye-axial, kodwa hhayi imithwalo ye-radial.

I-Trust ball bearingsakhiwe izingxenye ezintathu: i-washer yezihlalo, i-shaft washer kanye ne-steel ball cage assembly. Iwasha shaft ihambisana ne-shaft kanye neringi yesihlalo ihambisana nendlu. Ama-thrust ball bearings afanele kuphela izingxenye ezithwala umthwalo we-axial ohlangothini olulodwa futhi anejubane eliphansi, njengamahhuku e-crane, amaphampu amanzi amile, ama-centrifuge amile, ojeke, izinciphisi ezinesivinini esiphansi, njll. ye-bearing iyahlukaniswa futhi ingahlanganiswa futhi ihlakazwe ngokwehlukana.
