Ama-bearings ayizingxenye ezilungisa futhi zinciphise i-load friction coefficient ngesikhathi sokudlulisa ngomshini. Kungashiwo futhi ukuthi lapho ezinye izingxenye zikhiqiza ukunyakaza okuhlobene ku-shaft, isetshenziselwa ukunciphisa i-friction coefficient ngesikhathi sokudlulisa ngamandla nokugcina indawo eqinile yesikhungo somshini. Ama-bearings ayizingxenye ezibalulekile emishinini yesimanje yemishini. Umsebenzi wayo oyinhloko ukusekela umzimba ojikelezayo wemishini ukunciphisa i-mechanical load friction coefficient yemishini ngesikhathi senqubo yokudlulisa. Ngokwezakhiwo ezahlukene zokungqubuzana kwezingxenye ezihambayo, ama-bearings angahlukaniswa ngezinhlobo ezimbili: ama-rolling bearings nama-sliding bearings. 1, Kukhona i-angle yokuxhumana phakathi kokuxhumana kwe-angularibhola elithwalayoindandatho nebhola. Ama-engeli okuxhumana ajwayelekile angama-15 °, 30 °, kanye nama-40 °. Uma i-engeli yokuxhumana inkulu, kulapho umthamo womthwalo we-axial uba mkhulu khona. Uma i-engeli yokuxhumana incane, kulapho ivumela khona ukujikeleza ngesivinini esikhulu. Ama-bearings omugqa owodwa angamelana nemithwalo ye-axial e-radial kanye ne-unidirectional. Ngokwesakhiwo, ama-bearings amabili omugqa owodwa we-angular contact ball anenhlanganisela yangemuva abelana ngamasongo angaphakathi nangaphandle, angamelana nemithwalo ye-axial e-radial kanye ne-bidirectional. Ukusetshenziswa okuyinhloko kwama-bearings e-angular contact ball: umugqa owodwa: i-spindle yethuluzi lomshini, i-motor enemvamisa ephezulu, i-gas turbine, i-centrifugal separator, isondo elingaphambili lemoto encane, i-differential pinion shaft. Ikholomu ephindwe kabili: ipompo kawoyela, i-Roots blower, i-air compressor, ama-transmission ahlukahlukene, ipompo yokufaka uphethiloli, imishini yokunyathelisa. 2、 I-self-aligning ball bearing inemigqa emibili yamabhola ensimbi, kanti umjaho wangaphandle ungowohlobo lwangaphakathi lwebhola. Ngakho-ke, ingalungisa ngokuzenzakalelayo ukungalungi kahle kweshaft okubangelwa ukugoba noma ukungagxili kweshaft noma igobolondo. I-bearing yembobo enciphile ingafakwa kalula ku-shaft ngokusebenzisa izinamathiselo, ikakhulukazi ezithwala imithwalo ye-radial. Ukusetshenziswa okuyinhloko kwama-ball bearing azimele: imishini yokwenza ukhuni, imishini yokudlulisa imishini yendwangu, ama-bearing azimele esihlalo aqondile. 3, i-self aligning roller bearing Lolu hlobo lwe-bearing lufakwe ama-rollers ayindilinga phakathi kwendandatho yangaphandle ye-spherical raceway kanye nendandatho yangaphakathi ye-double raceway. Ngokwezakhiwo zangaphakathi ezahlukene, ingahlukaniswa ngezinhlobo ezine: R, RH, RHA, kanye ne-SR. Ngenxa yokuvumelana phakathi kwesikhungo se-arc se-outer raceway kanye nesikhungo se-bearing, inokusebenza kokuzilungisa. Ngakho-ke, ingalungisa ngokuzenzakalelayo ukungahambisani kwe-axis okubangelwa ukuphambuka noma ukungagxili kwe-shaft noma igobolondo, futhi ingamelana nokungahambisani kahle kwe-radial
