Mola o le mong oa li-angular ball bearings
Mela e le 'ngoe ea li-angular ball bearings e na le reng e ka ntle, selikalikoe sa ka hare, mola oa libolo tsa tšepe le cage. Mofuta ona oa ho jara o ka jara mojaro oa radial le axial load ka nako e le 'ngoe, hape o ka jara mojaro o hloekileng oa axial,' me o ka sebetsa ka lebelo le phahameng. Mola o le mong o ka mamella meroalo ea axial ka lehlakoreng le le leng. Ha e le tlas'a meroalo ea mahlaseli, matla a eketsehileng a axial a tla susumelletseha, 'me ho falla ha axial ea shaft le matlo ho ka fokotsoa ka tsela e le' ngoe feela. Le hoja mofuta ona oa ho jara o ka jara meroalo ea axial ka lehlakoreng le le leng, e ka kopanngoa le mojaro o mong o jarang meroalo ka lehlakoreng le leng. Haeba e kentsoe ka lipara, lifahleho tse tšoanang tsa pheletso ea mehele e ka ntle ea li-bearings li shebane, pheletso e pharaletseng e shebane le bophara.
le sefahleho (DB-back-to-back), mme pheletso e moqotetsane e shebane le sefahleho se moqotetsane (sefahleho le sefahleho DF), e le ho qoba ho baka matla a eketsehileng a axial, Hape, shaft kapa ntlo e ka lekanyetsoa ho bapala axial. ka nqa tse pedi.
Mola o le mong oa li-angular ball bearing o na le libolo tse ngata ho feta tekano ea bolo ea groove ea boholo bo lekanang, kahoo mojaro o lekantsoeng ke o moholo ka ho fetisisa oa bolo, ho thatafala ho boetse ho matla, 'me ts'ebetso e tsitsitse. Sehlahisoa sa mahlaseli se ka fetoloa ka ho falla ha mehele ea ka hare le ea ka ntle, 'me lihlopha tse' maloa tsa li-bearings li ka kopanngoa ka tsela e tšoanang ho etsa hore ho be le tšitiso ea pele ho ntlafatsa ho tiea ha tsamaiso.
Tšebeliso ea li-angular ball bearings e ke ke ea qhaqhoa, 'me bokhoni ba eona ba ho ikamahanya le bona bo fokotsehile haholo.
Tšobotsi ea mofuta ona oa ho jara ke hore angle ea ho kopana ha se zero, 'me li-angles tse tloaelehileng tsa ho kopana tsa mela e le' ngoe ea li-angular ball bearings ke 15 °, 25 °, 30 °, le 40 °. Boholo ba angle ea ho kopana bo etsa qeto ea matla a radial le axial force eo bering e ka e mamellang nakong ea ts'ebetso. Ha e le kholoanyane angle ea ho kopana, e kholoanyane matla a axial a ka mamella. Leha ho le joalo, ha karolo ea ho kopana e le nyane, ho na le monyetla oa ho potoloha ka lebelo le phahameng.
Mola o le mong oa li-angular ball bearings ha li na tumello ea tlhaho. Ke feela li-angular contact ball bearings tse nang le tumello ea ka hare. Ho ea ka litlhoko tsa maemo a ho sebetsa, ho na le mekhoa e 'meli ea ho fana ka li-bearings tse kopaneng: preload (preload) le preclearance (preset clearance). Phallo e ka hare ea li-bearings tsa li-angular ball bearings ke zero kapa tse mpe. Hangata e sebelisoa holim'a li-spindle tsa lisebelisoa tsa mochini ho ntlafatsa ho tiea le ho nepahala ho potoloha ha spindle. Tlhokomelo (ho kenya pele) ea li-bearings tsa li-angular ball e fetotsoe pele e tloha fekthering, 'me ha ho na tokiso ea mosebedisi e hlokahalang. Mamello e kholo ea bophara le ho hlahisa sefahleho sa ho qetela sa li-bearings tse tloaelehileng tsa mola o le mong oa li-angular li hlahisoa feela ho ea ka limaraka tse tloaelehileng, 'me li ke ke tsa kopanngoa le ho kopanngoa ka thato.
Ho hlahisoa ha li-angular ball bearings tse kopaneng tsa bokahohleng li ka bokelloa ka tsela efe kapa efe, joalo ka ho khutlela morao, sefahleho le sefahleho kapa ka letoto. Ho na le mekhoa e 'meli ea ho fana ka li-bearings tsa bokahohleng: preload (preload) le preclearance (preset clearance). Ntle le li-bearings tse kopaneng tsa bokahohleng, li-bearings ka bomong ho li-bearings tse ling tse bokaneng ha li fetohe.
Li-bearings tsa bolo ea mela e 'meli
Moralo oa li-bearings tsa libolo tse nang le mela e 'meli o tšoana hantle le oa mela e le 'ngoe, empa o nka sebaka se senyenyane sa axial. Mela e 'meli ea li-angular ball bearings e ka mamella meroalo ea radial le meroalo ea axial e sebetsang ka mahlakoreng ka bobeli. Litokisetso tse phahameng tsa ho jara li-rigidity li teng 'me li ka mamella linako tsa ho phethola.
Mola o le mong oa li-angular ball bearings le li-bearings tse kopantsoeng tsa li-angular
E le ho ntlafatsa matla le ho jara boima ba li-angular ball bearings, li-angular ball bearings tsa litlhaloso tse tšoanang li atisa ho bokelloa ka makhetlo a mabeli (QBCQFC, QT) kapa esita le quintuple (PBC, PFC, PT, PBT, PFT) mefuta. Bakeng sa li-bearings tsa li-angular tse peli, mekhoa ea ho hlophisa e arotsoe ka mefuta e meraro: ho khutlela morao (DB), sefahleho le sefahleho (DF), le tandem (DT). Li-back-to-back angular ball bearings li loketse ho jara meroalo e arohaneng kapa e kopaneng ea radial le axial, 'me e khona ho mamella meroalo ea axial ea bidirectional. E ka mamella nako e kholo ea ho phethola 'me e na le ho tiea ho matla. Li-preloads tse fapaneng li ka sebelisoa ho latela maemo a ts'ebetso. Li-angular contact ball bearings li na le linako tse fokolang tsa ho phethoha 'me li fana ka boima bo tlaase ba tsamaiso. Molemo ke hore ha e na kutloelo-bohloko ho jara liphoso tsa concentricity ea matlo. Li-angular ball bearings tse hlophisitsoeng ka lihlopha li lumelloa feela ho jara mojaro o moholo oa axial ka lehlakoreng le le leng. Maemong a mangata, ho sebelisoa selemo ho kenya kopo pele, 'me palo ea radial load e ka tšehetsoang le ho tiea ha ho bea ho itšetlehile ka boleng bo khethiloeng pele.
