Ukubopha Nge-Sleeve Sleeve Kusekela umzimba ojikelezayo womshini

Ukubeletha yingxenye ebalulekile yemishini yanamuhla. Umsebenzi wayo oyinhloko ukusekela umzimba ojikelezayo, ukunciphisa ukulingana kokuhamba kwawo, nokuqinisekisa ngokunemba kwawo.

Ukubhekwa kungahlukaniswa zibe yizinhlobo ezimbili: ukuguqa ukubheja nokuthwala ukusalalisa, ngokusho kokubhikisana kwento ehamba phambili. Ukukhiqiza okubekwe eceleni kuye kwabekwa ngendlela ejwayelekile futhi kusetshenzisiwe, kodwa kunesidingo esikhulu se-radial, vibration nomsindo uma kuqhathaniswa nokubheja kwe-bearings, futhi inani liphakeme.

Imibala ye-Rolling ngokuvamile ihlanganisa indandatho yangaphandle, indandatho yangaphakathi, umzimba oguqa futhi ugcine ifreyimu yezingxenye ezine, eqinile, indandatho yangaphandle, indandatho yangaphakathi, umzimba oguqa, inqolobane, uphawu, amafutha okugcoba izingxenye eziyisithupha. Kalula nje, uma nje unemibuthano yangaphandle, imibuthano yangaphakathi, nabaphequluli bangachazwa njengama-bearings akhazimulayo. Ama-bearings akhazimulayo ahlukaniswe amabhethri amabhola kanye nama-roller bearings ngokuma komzimba ohambayo.

Esikhathini sokuqala sezingubo zokuhamba ezihamba phambili, uhlaka lwamapulangwe okhuni lwafakwa ngaphansi kwemigqa yepry. Izindwangu zanamuhla ezihamba phambili zisebenza ngokufanayo, kodwa ngezinye izikhathi zisebenzisa ibhola esikhundleni se-roller. Ukuhamba okulula okuhambayo yi-shaft bearing, okuyi-bushing phakathi kwesondo kanye ne-wheel shaft. Umklamo usuke uthathe indawo yendawo yokugqoka, efaka esikhundleni se-liner yangempela enezingxube eziningi ze-cylindrical, ngasinye sinevili elilodwa.

I-Nanoscale echibini lase-Italy ithola umkhumbi owakhiwe eminyakeni engu-40 e-Roma eRoma lasendulo, watholakala izibonelo zakuqala zebhola elibhekene nalokhu: ibhola lezinkuni elisetshenziswayo ukusekela itafula elijikelezayo. U-Leonardo Da Vinci kuthiwa ukhulume ibhola elibhekene no-1500. Enye yezinto ezibalulekile mayelana nokubheja kwebhola ukuthi kukhona ukushayisana phakathi kwebhola, okwenza kube khona ukungqubuzana okwengeziwe. Kodwa ungakuvimbela ngokubeka ibhola emgodini omncane. Ngekhulu le-17, uGalileo waqala ukuchaza ibhola eliphethe ibhola. Ekupheleni kwekhulu le-17, iBritish c. i-rocklow eyakhelwe futhi ibanjwe ibhola yebhola, evivinywe enqoleni yeposi futhi enegunya lobunikazi nge-p. kufanelekile. Enye yezingubo zokuqala eziwusizo kakhulu futhi ewusizo kwakuyi-clockmaker uJohn ubhekana, owasungulwa i-H3 chronometer ngo-1760. Ekupheleni kwekhulu le-18, i-H.R. Hertz yaseJalimane yanyathelisa iphepha lokucindezeleka kwamabherebhe ebhola. Ekuphumeleleni kwe-Hertz, ngesisekelo se-r sikaJalimane. a. i-terry baker, i-Sweden PAM glen kanye nabanye Ukuhlolwa okuningi kuye kwaqhutshwa, ukuthuthukisa umklamo we-rolling bearing bearing and calculation life calculation. Khona-ke i-Russian N.P. i-petrov isebenzise umthetho kaNewton we-viscosity ukubala ukuhlukunyezwa kokuthwala. I-patent yokuqala yesiteshi sebhola yanikezwa nguFiliphu vaughn ngo-1794.
