Ama-Angular Contact Ball Bearings: Nika amandla Ukujikeleza Okunembile Ngaphansi Kwemithwalo Ephezulu

Ama-angular contact bearings, uhlobo lwebhola elithwele ngaphakathi kwama-rolling bearings, akhiwe ngendandatho yangaphandle, iringi yangaphakathi, amabhola ensimbi, kanye nekheji. Kokubili amasongo angaphakathi nangaphandle afaka imigwaqo yomjaho evumela ukugudluka okuhlobene kwe-axial. Lawa ma-bearings afaneleka ngokukhethekile ukuphatha imithwalo eyinhlanganisela, okusho ukuthi angakwazi ukuthwala kokubili amandla e-radial kanye ne-axial. Isici esiyinhloko i-engeli yokuxhumana, ebhekisela ku-engeli ephakathi komugqa oxhuma izindawo zokuthintana zebhola kumzila womjaho endizeni yomsakazo kanye nomugqa oqondile we-eksisi ephethe. I-engeli yokuxhumana enkulu inyusa ikhono le-axial lokuphatha imithwalo ye-axial. Kumabheringi ekhwalithi ephezulu, i-engeli yokuxhumana engu-15° ivamise ukusetshenziselwa ukunikeza umthamo owanele womthwalo we-axial kuyilapho kugcinwa izivinini eziphezulu zokujikeleza.

Amabheringi angama-angular anomugqa owodwaingasekela imithwalo ye-radial, axial, noma eyinhlanganisela, kodwa noma yimuphi umthwalo we-axial kufanele usetshenziswe ohlangothini olulodwa kuphela. Uma imithwalo ye-radial isetshenziswa, amandla e-axial engeziwe akhiqizwa, adinga umthwalo ohambisanayo obuyela emuva. Ngenxa yalesi sizathu, lawa ma-bearings ngokuvamile asetshenziswa ngababili.

Ama-angular contact bearings anemigqa emibiliingakwazi ukuphatha imithwalo ehlanganisiwe ye-radial kanye ne-bidirectional axial ehlanganisiwe, futhi imithwalo ye-radial iyisici esiyinhloko, futhi ingasekela imithwalo ye-radial kuphela. Ukwengeza, bangakwazi ukukhawulela ukuhamba kwe-axial kuzo zombili izinkomba ze-shaft noma izindlu.

Ukufaka ama-angular contact ball bearings kuyinkimbinkimbi kakhulu kunama-deep groove ball bearings futhi ngokuvamile kudinga ukufakwa okubhanqiwe nokulayisha kuqala. Uma ifakwe kahle, ukunemba nempilo yesevisi yemishini ingathuthukiswa kakhulu. Uma kungenjalo, ngeke nje yehluleke ukuhlangabezana nezimfuneko zokunemba, kodwa ukuphila isikhathi eside kwebheringi nakho kuzophazamiseka.

Kunezinhlobo ezintathu zeama-angular amabhola okuxhumana: ukulungiswa kwe-back-to-back, ubuso nobuso kanye ne-tandem.
1. I-Back-to-Back - ubuso obubanzi bama-bearings amabili buphambene, i-angle yokuxhumana ye-bearing isakazeka eduze kokuqondisa kwe-axis of rotation, okungakhuphula ukuqina kwama-angles ayo asekela i-radial kanye ne-axial, kanye nobukhulu obukhulu. ikhono le-anti-deformation;
2. Ubuso-ngobuso - ubuso obuncane bama-bearings amabili buphambene, i-angle yokuxhumana ye-bearing iguqukela ekuqondeni kwe-axis of rotation, futhi ukuqina kwe-angle yokuthwala kuncane. Ngenxa yokuthi indandatho yangaphakathi yokuthwala iphumela ngaphandle kwendandatho yangaphandle, lapho indandatho yangaphandle yamabhorethi amabili icindezelwa ndawonye, ​​imvume yokuqala yeringi yangaphandle iyasuswa, futhi ukulayishwa kwangaphambili kokuthwala kungandiswa;
3. Ukuhlelwa kwe-Tandem - ubuso obubanzi bezinsimbi ezimbili buyisiqondiso esisodwa, i-angle yokuxhumana ye-bearing isendleleni efanayo futhi ihambisana, ukuze ama-bearings amabili ahlanganyele umthwalo wokusebenza ngendlela efanayo. Kodwa-ke, ukuze kuqinisekiswe ukuzinza kwe-axial kokufakwa, amapheya amabili ama-bearings ahlelwe ngochungechunge kufanele afakwe ngokuphambene komunye nomunye kuzo zombili iziphetho ze-shaft. Umugqa owodwa wamabhola angama-angular athintana naye ekuhlelweni kwe-tandem kufanele ngaso sonke isikhathi alungiswe ngokumelene nelinye ibheyili ehlelwe ngokuphambene ukuze iqondiswe ku-shaft kwelinye icala.

Siyakwamukela kubonisanaimikhiqizo ehlobene kakhulu nezixazululo zobuchwepheshe. Kusukela ngo-1999, besihlinzekaizixazululo ezinokwethenjelwakubakhiqizi bezimoto kanye ne-Aftermarket. Izinsizakalo ezenziwe ngomthungo ziqinisekisa ikhwalithi nokusebenza.
