Lihlahisoa tsa indasteri: mefuta, tataiso ea khetho le libaka tsa kopo
Li-Industrial bearings ke karolo ea bohlokoa ea lisebelisoa tsa mochini. Ba netefatsa ts'ebetso e sebetsang hantle le e tsitsitseng ea lisebelisoa ka ho fokotsa likhohlano le ho tšehetsa motsamao oa ho potoloha. Ebang ke koloi, mochini o fehlang moea, kapa mochine oa tlhahiso ea fektheri, li-bearing li phetha karolo ea bohlokoa. Sengoliloeng sena se tla hlahloba mefuta ea li-bearings tsa indasteri, mokhoa oa ho khetha li-bearings tse nepahetseng, lintlha tsa khetho le ts'ebeliso ea tsona e pharaletseng ho u thusa ho utloisisa hantle karolo ena ea bohlokoa.
1. Ke englihlahisoa tsa indasteri?
Li-bearings tsa indasteri ke karolo e nepahetseng ea mochini e sebelisoang haholo ho ts'ehetsa 'mele o potolohang oa mochini (joalo ka shafts, likere kapa mabili), ho fokotsa likhohlano nakong ea ho sisinyeha, le ho mamella meroalo ea radial kapa axial e tsoang lisebelisoa. Mosebetsi oa eona oa mantlha ke ho netefatsa boreleli, ho nepahala le bophelo bo bolelele ba motsamao oa mochini.
2. Mefuta e ka sehloohong ea li-bearings tsa indasteri
Ho ipapisitsoe le sebopeho le molao-motheo oa ts'ebetso, li-bearings tsa indasteri li ka aroloa ka mekhahlelo e latelang:
- Li-bearings
Deep groove ball bearings: mofuta o tloaelehileng ka ho fetisisa, o loketseng lebelo le bohareng le le tlaase, meroalo e khanyang le e bobebe ea axial, e kang li-motors le lisebelisoa tsa ntlo.
Angular contact ball bearings: e ka mamella meroalo ea radial le axial ka nako e le 'ngoe, e sebelisoang hangata ho li-spindle tsa lisebelisoa tsa mochini, lipompo, joalo-joalo.
Li-roller bearings: E etselitsoe ho mamella meroalo e boima ea radial le axial, e sebelisoang haholo mabiling a likoloi le li-gearbox.
Li-cylindrical roller bearings: Bophahamo bo phahameng ba radial load, bo loketseng mechini e boima (joalo ka li-turbine tsa moea).
- Li-sliding bearings (li-plane bearings)
Sebetsa ka likhohlano tse thellang, ha ho na lintho tse bilikang tse hlokahalang, 'me hangata li sebelisoa maemong a lebelo le tlase, a boima bo phahameng (joalo ka li-turbine, litsamaiso tsa ho tsamaisa likepe).
- Li-thrust bearings
E etselitsoe ka ho khetheha ho mamella meroalo ea axial, joalo ka lisebelisoa tsa helical gearboxes.
- Li-bearings tse khethehileng tsa boemo ba ho sebetsa
Li-Ceramic bearings: Mocheso o phahameng le ho hanyetsa kutu, tse loketseng libaka tse feteletseng (tse kang sefofane, lisebelisoa tsa lik'hemik'hale).
Li-bearings tsa ho itlotsa: Ha ho hlokahale hore ho be le lubrication ea ka ntle, e sebelisoang maemong a thata a tlhokomelo (joaloka mechine ea lijo, lisebelisoa tsa bongaka).
3. Mokhoa oa ho khetha thepa e nepahetseng ea indasteri?
Lintlha tse latelang li lokela ho nahanoa ka botlalo ho khetha sebaka se nepahetseng:
1. Mofuta oa mojaro le boholo
Radial load: Qobella perpendicular ho axis (joalo ka ho hula ha pulley).
Axial load: Qobella ho bapa le axis (joalo ka ho sututsa ha mesh ea likere).
Mojaro o tsoakiloeng: Li-angular contact bearings kapa li-rolara tse tapered lia hlokahala.
2. Litlhokahalo tsa lebelo
Deep groove ball bearingskapa li-ceramic bearings li ratoa bakeng sa lisebelisoa tsa lebelo le phahameng (joalo ka li-spindle tsa motlakase).
Li-cylindrical rolara diberingli loketse maemo a lebelo le tlase le mojaro o boima (joalo ka li-cranes).
3. Tikoloho ea mosebetsi
Mocheso: Litšepe tse sa keneleng mocheso kapa li-ceramic bearings lia hlokahala bakeng sa maemo a phahameng a mocheso; grease ea antifreeze ea hlokahala bakeng sa maemo a tlase a mocheso.
Corrosiveness: tšepe e sa hloekang kapa li-bearings tse koahetsoeng li ka khethoa bakeng sa lisebelisoa tsa lik'hemik'hale.
Litlhoko tsa ho tiisa: Li-bearings tse nang le sekoahelo sa lerōle kapa mehele ea ho tiisa lia hlokahala bakeng sa libaka tse lerōle kapa tse mongobo.
4. Ho kenya le tlhokomelo
Na ho bonolo ho kenya? Li-bearings tse arohaneng li ka nolofatsa tlhokomelo.
Na ho lokela ho etsoa lubrication khafetsa? Li-bearings tse itšebetsang li ka fokotsa litšenyehelo tsa tlhokomelo.
IV. Litaelo tsa khetho
Qoba "ho feta tekano": khetha ho latela maemo a sebele a ho sebetsa, ntle le ho latela lintlha tse phahameng ka bofofu.
Nahana ka litšenyehelo tsohle: li-bearings tsa theko e tlaase li ka ba le bophelo bo khutšoanyane, e leng se bakang litšenyehelo tse phahameng tsa ho nchafatsa le ho li hlokomela.
Tšehetso ea botekgeniki ea barekisi: Khetha mofuta o tšepahalang o ka fanang ka lintlha tsa tekheniki le litaelo tsa ho kenya (joalo ka SKF, NSK, TIMKEN). TP e ka u fa likhetho tse ikhethileng bakeng sa hau.
Tlhahlobo ea ho lumellana: Etsa bonnete ba hore boholo ba thepa bo lumellana le shaft ea thepa le ntlo.
V. Libaka tse tloaelehileng tsa kopo ea li-bearings tsa indasteri
Indasteri ea likoloi: mabili hub bearings, li-gearbox bearings,likarolo tsa enjene.
Indasteri ea matla: li-bearings tsa mantlha tsa turbine tsa moea, li-bearings tsa tšehetso tsa hydraulic turbine.
Indasteri ea tlhahiso: li-spindle tsa lisebelisoa tsa mochini, li-bearings tse kopaneng tsa liroboto tsa indasteri.
Aerospace: li-bearings tsa enjine tse hanyetsanang le mocheso o phahameng, li-gear bearings.
Lisebelisoa tsa lapeng le lihlahisoa tsa elektroniki: li-motor bearings, li-spindle bearings tsa hard disk drive.
Leha ho le joalolihlahisoa tsa indasterili nyenyane, ke "mohlokomeli ea sa bonahaleng" oa ho sebetsa ka katleho ha mechine ea kajeno. Ho khetha ka mokhoa o nepahetseng mefuta ea ho beleha le maemo a ts'ebetso a ts'oanang hantle ho ke ke ha ntlafatsa ts'ebetso ea lisebelisoa feela, empa hape ho eketsa bophelo ba ts'ebeletso le ho fokotsa litšenyehelo tsa ts'ebetso le tlhokomelo. E kgothaletswa ho sebetsa haufi-ufi lebafani ba litsebiha u khetha mehlala le ho etsa qeto e molemo ka ho fetisisa ho latela maemo a itseng a kopo.
Haeba u hloka ho ithuta ho eketsehileng ka khetho ea lihlahisoa kapa ho fumana libuka tsa lihlahisoa, ka kopotshoanyasehlopha sa rona sa tekheniki!
