Ama-Angular Contact Ball Bearings: Nika amandla ukujikeleza okunembile ngaphansi kwemithwalo ephezulu

Ama-bearing okuxhumana angama-angular, uhlobo lwe-ball bearing ngaphakathi kwama-rolling bearing, akhiwe yindandatho yangaphandle, indandatho yangaphakathi, amabhola ensimbi, kanye nekheji. Zombili izindandatho zangaphakathi nezangaphandle zinezindlela zokugijima ezivumela ukufuduka kwe-axial okuhlobene. Lawa ma-bearing afaneleka kakhulu ekusingatheni imithwalo ehlanganisiwe, okusho ukuthi angamukela amandla e-radial kanye ne-axial. Isici esibalulekile yi-angle yokuxhumana, ebhekisela ekhoneni eliphakathi komugqa oxhumanisa amaphuzu okuxhumana ebhola endleleni yokugijima endizeni ye-radial kanye nomugqa oqondile ku-axis yokuthwala. I-angle enkulu yokuxhumana yandisa ikhono le-bearing lokusingatha imithwalo ye-axial. Kuma-bearing asezingeni eliphezulu, i-angle yokuxhumana engama-15° ivame ukusetshenziselwa ukuhlinzeka ngomthamo owanele womthwalo we-axial ngenkathi kugcinwa isivinini esiphezulu sokujikeleza.

Amabheringi okuxhumana angular anomugqa owodwaingasekela imithwalo ye-radial, ye-axial, noma ehlanganisiwe, kodwa noma yimuphi umthwalo we-axial kumele usetshenziswe ohlangothini olulodwa kuphela. Lapho kusetshenziswa imithwalo ye-radial, kukhiqizwa amandla e-axial engeziwe, adinga umthwalo ohambisanayo obuyela emuva. Ngenxa yalesi sizathu, lawa ma-bearings avame ukusetshenziswa ngamabili.

Amabheringi okuxhumana angama-angular anemigqa emibilizingaphatha imithwalo emikhulu ehlanganisiwe ye-axial e-radial kanye ne-bidirectional, kanti imithwalo ye-radial iyisici esiyinhloko, futhi zingasekela imithwalo ye-radial kuphela. Ngaphezu kwalokho, zingavimbela ukufuduka kwe-axial kuzo zombili izinhlangothi ze-shaft noma ze-housing.

Ukufaka ama-angular contact ball bearings kuyinkimbinkimbi kakhulu kune-deep groove ball bearings futhi ngokuvamile kudinga ukufakwa okubhangqiwe nokulayisha kusengaphambili. Uma kufakwe kahle, ukunemba kanye nokuphila kwenkonzo yemishini kungathuthukiswa kakhulu. Ngaphandle kwalokho, ngeke nje ihluleke ukuhlangabezana nezidingo zokunemba, kodwa futhi nobude be-bearings buzophazamiseka.

Kunezinhlobo ezintathu ze-amabheringi ebhola lokuxhumana eliyi-angular: ukuhlelwa ngokulandelana, ubuso nobuso kanye ne-tandem.
1. Ukubuyela Emuva - ubuso obubanzi bamabhereyi amabili buphambene, i-engeli yokuxhumana yebhereyi isakazeka eceleni kwe-axis yokujikeleza, okungandisa ukuqina kwama-engeli ayo okusekela e-radial kanye ne-axial, kanye nekhono eliphezulu lokulwa nokuguquka;
2. Ubuso Nobuso - ubuso obuncane bamabhereyi amabili buphambene, i-engeli yokuxhumana yebhereyi ihlangana ibheke ohlangothini lwe-axis yokujikeleza, futhi ukuqina kwe-engeli yebhereyi kuncane. Ngenxa yokuthi indandatho yangaphakathi yebhereyi idlula ngaphandle kwendandatho yangaphandle, lapho indandatho yangaphandle yamabhereyiyi amabili icindezelwa ndawonye, ​​​​ukuphuma kokuqala kwendandatho yangaphandle kuyasuswa, futhi umthwalo wangaphambi kwebhereyi ungandiswa;
3. Ukuhlelwa kwe-Tandem - ubuso obubanzi bama-bearings amabili busehlangothini olulodwa, i-engeli yokuxhumana ye-bearings isendaweni efanayo futhi ihambisana, ukuze ama-bearings amabili akwazi ukwabelana ngomthwalo osebenzayo ohlangothini olufanayo. Kodwa-ke, ukuze kuqinisekiswe ukuzinza kwe-axial kokufakwa, ama-bearings amabili ahlelwe ngokulandelana kumele afakwe abhekene kuzo zombili iziphetho ze-shaft. Ama-bearings ebhola lokuxhumana elingumugqa owodwa kulungiselelo lwe-tandem kumele ahlale elungiswa ngokumelene nelinye i-bearings elihlelwe ngendlela ephambene ukuze kuqondiswe i-shaft ohlangothini oluphambene.

Siyakwamukela ku-bonisanaimikhiqizo ehlobene kakhulu nezixazululo zobuchwepheshe. Kusukela ngo-1999, besilokhu sihlinzekaizixazululo zokuthwala ezinokwethenjelwakubakhiqizi bezimoto kanye ne-Aftermarket. Izinsizakalo ezenzelwe wena ziqinisekisa ikhwalithi nokusebenza kahle.
