Ngokuhlaziya izici zesakhiwo samakheji omkhiqizo wasekhaya nakwamanye amazwe ohlobo olufanayo, futhi ebhekisela endleleni yamanje yokuklama yesakhiwo samakheji okugxiviza ensimbi ama-roller bearings anomugqa owodwa e-China, ukwakheka kwesakhiwo kanye nomklamo wamakheji epulasitiki ama-double- kuxoxwa ngama-roller bearings amasondo ezimoto.Ukubalwa kwamapharamitha ayinhloko.Amagama angukhiye: imigqa ephindwe kabili ene-tapered roller bear;i-wheel hub bear;ikheji lepulasitiki;1 Ikhodi yedokhumenti: B Inombolo ye-athikili: 1000-3762 (2008) 06-0007-03 Incazelo yophawu D ——Ububanzi bomkhawulo omkhulu werola, mmD.——Ububanzi bomkhawulo omncane werola, mm————Ubude obuqageliwe bomugqa wesici werola emugqeni ophakathi nendawo werola, mm Usuku okwamukelwe ngalo: 2007-10-18;Idethi ebuyekeziwe: 2008-01-30.(b——i-engeli ephakathi komugqa wesici werola nomugqa wayo omaphakathi, (.)—i-engeli yokuthintana yebheringi, (.) i-engeli phakathi kwe-cage beam kanye ne-centerline yokuthwala, (.)—ingcindezi umthambeko we-engeli yogodo lwekheji, (.)△c– ububanzi bomkhawulo omkhulu wembobo yewindi lekheji, mmAC.–ububanzi bomkhawulo omncane wembobo yewindi lekheji, mmZ.–ubude bembobo yewindi lekheji , Umdwebo 3 we-Hun ubonisa ukuhluka kwamandla okungqubuzana angenasici ngesivinini esijikelezayo esingenasici.

Kungabonakala esibalweni ukuthi njengoba isivinini sokuzungeza sikhula, amandla okungqubuzana angenasici kanye nesivinini esizungezayo akuhambisani ngokuphelele.Uma ijubane lokujikeleza liphansi, amandla okungqubuzana athinteka kakhulu isivinini sokujikeleza;lapho isivinini sokuzungeza siphezulu, umthelela wejubane elizungezayo kumandla okungqubuzana kancane kancane uthambekele ekuzinzeni, futhi amandla okungqubuzana nesivinini sokuzungeza anobuhlobo obuseduze bomugqa.Ngokuvamile, izimo zokusebenza ezijwayelekile zingezalesi sifunda somugqa.Isithombe 3 Ubudlelwano phakathi kwamandla okungqubuzana angenasici kanye nesivinini sokuzungeza esingenasici.

Isiphetho (1) Ngokukhula kwejubane lokujikeleza, izinguquko zebanga eliqondile kanye nokuqondisa okuqondile akukona umugqa, futhi ijubane lokushintsha liyancipha kancane kancane, futhi ekugcineni livame ukuzinza.(2) Kukhona futhi ubudlelwano obungaqondile phakathi kwejubane lokuzungeza nokungqubuzana, okubonakala ikakhulukazi ngesikhathi sokuqalisa;ngaphansi kwezimo ezijwayelekile zokusebenza, ubudlelwano phakathi kwakho kokubili bucishe bulingane futhi bungabhekwa njengobudlelwano bomugqa .Izikhombo: [1] Yan Qinghua, An Qi.Ukusebenza kwe-three wedge fixed pad bearing ngesikhathi senqubo yokuqalisa [J].Ijenali yase-East China University of Science and Technology: I-Natural Science Edition, 2007, 33(4): 569-572.[2] Gao Lei, Liu Jun, An Qi.Ukuhlaziywa kwezinombolo kwe-cylindrical arc wedge kawoyela wedge thrust bearing[J].Ukugcotshwa nokubekwa uphawu, 2007, 32(8): 99-102.[3] Yan Qinghua, An Qi.Ucwaningo ngomthelela we-oil wedge egxilile yephedi eslayidayo enomumo wokufakwa kwesikhala ekusebenzeni kwayo[J].I-China Mechanical Engineering, 2007, 18(11): 1281-1284.[4] Yan Qinghua, Yan Yongming, An Qi.Umthelela we-coefficient yokulayisha kuqala ekuzinzeni kwebheringi ye-radial ye-wedge yamafutha amathathu[J].Ijenali yaseMpumalanga China University of Science and Technology: Natural Science Edition, 2006, 32(11): 1365—1368.[5] Yan Qinghua, An Qi.Umthelela wamapharamitha ambalwa eweji yamafutha amathathu ehambisana nesivinini sokungaqini kwerotha eqinile nenwebekayo[J].Ijenali yase-East China University of Science and Technology: I-Natural Science Edition, 2007, 33(5): 737-740.[6] Yan Qinghua, An Qi.Umthelela wamapharamitha wesakhiwo sephedi egxilile yamafutha amathathu ehambisana nesivinini sokungaqini se-Jefeott rotor[J].Amathuluzi Omshini namaHydraulics, 2007, 35(9): 35-36.[7] Sehulhr Fredrick T.
