Bearing ea bolo e tebileng e tsebahala ka ho tšepahala ha eona libakeng tse tloaelehileng tsa indasteri, empa boenjiniere ba sejoale-joale hangata bo hloka ho feta moo. Ho tloha tundra e leqhoa ho ea pelong ea sebōpi, ho tloha libateng tsa lik'hemik'hale ho ea ho vacuum ea sebaka, lisebelisoa li tlameha ho sebetsa maemong a sutumelletsang likarolo ho fihlela meeling ea tsona. Sena se hlahisa potso ea bohlokoa: na bearing ea bolo e tebileng ea khale e ka mamella maemo a feteletseng joalo, hona e entsoe joang ho etsa joalo?
Sekhahla sa Phephetso: Ka Nģ'ane ho Maemo a Tloaelehileng a Ts'ebetso
Tikoloho e feteletseng e hlahisa litlhaselo tse ikhethang holim'a botšepehi ba ho jara:
Maemo a Mocheso a Feteletseng:Dithempereichara tse ka tlase ho lefela di teteanya mafura le thepa e qhibidihang, ha dithempereichara tse phahameng di senya mafura, di nolofatsa ditshipi, mme di baka katoloso ya mocheso.
Ts'enyeho le Lik'hemik'hale:Ho pepesehela metsi, li-acid, li-alkali, kapa li-solvent ho ka phunya le ho senya tšepe e tloaelehileng e nang le bearing.
Tšilafalo: Lintho tse bonojoana tse benyang (lerōle, lehlohlojane), likaroloana tse tsamaisang motlakase, kapa thepa ea khoele li ka kenella, tsa baka ho tsofala ho potlakileng le tšenyo ea motlakase.
Likamore tse Hloekisang ka ho Fetisisa kapa tse nang le Vacuum e ngata:Litlolo li ka ntša peterole, tsa silafatsa tikoloho, ha mafura a tloaelehileng a sa sebetse.
Litharollo tsa Boenjiniere: Ho Lokisetsa Tekanyo ea ho Bearing
Ho tobana le liphephetso tsena, bearing e tloaelehileng ea groove e tebileng e fetoloa ka thepa e khethehileng, mekhoa ea phekolo le meralo.
1. Ho Hlōla Maemo a Feteletseng a Thempereichara
Li-Bearings tsa Mocheso o Phahameng: Sebelisa litšepe tse tsitsitseng mocheso (joalo ka litšepe tsa lisebelisoa), mafura a entsoeng ka ho khetheha a mocheso o phahameng (silicone, perfluoropolyether), le likheo tse entsoeng ka tšepe e koahetsoeng ka silevera kapa li-polymer tsa mocheso o phahameng (polyimide). Tsena li ka sebetsa ka ho tsoelang pele mochesong o fetang 350°C.
Li-bearings tsa Cryogenic: Li etselitsoe lipompo tsa khase tse metsi le lits'ebetso tsa lifofane. Li sebelisa thepa e bolokang ho tiea mochesong o tlase haholo (mohlala, litšepe tse sa hloekang tse itseng), litlolo tse khethehileng tse kang molybdenum disulfide kapa metsoako e thehiloeng ho PTFE, le sebaka se nepahetseng sa ka hare ho ikarabella bakeng sa ho honyela ho matla ha thepa.
2. Ho Loantša Tšenyo le Lik'hemik'hale
Li-Bearings tsa Tšepe e sa Ruseng: Tšireletso ea mantlha. Tšepe e sa Ruseng ea Martensitic 440C e fana ka khanyetso e ntle ea mafome le ho ba thata. Bakeng sa libaka tse mabifi haholoanyane (lijo, meriana, tsa leoatle), ho sebelisoa libolo tsa tšepe e sa ruseng ea AISI 316 kapa tsa ceramic (silicon nitride) tse hanelang mafome haholo.
Liaparo le Mekhoa e Ikhethang ea ho Phekola: Libaka tse ka holimo li ka manehoa ka black oxide, zinc-nickel, kapa li-polymer tse entsoeng ka boqapi joalo ka Xylan® ho fana ka thibelo e sa senyeheng khahlanong le lintho tse senyang.
3. Ho Tiisa Khahlanong le Tšilafalo
Libakeng tse litšila haholo kapa tse mongobo, sistimi ea ho koala ke eona tsela ea pele ea tšireletso. Sena se feta litiiso tsa rabara tse tloaelehileng.
Litharollo tsa ho Tiea ka Boima: Ho sebelisoa litiiso tse kopanang le molomo o tharo, tse entsoeng ka metsoako e hananang le lik'hemik'hale joalo ka FKM (Viton®). Bakeng sa libaka tse khohlang ka ho fetisisa, litiiso tsa labyrinth tse kopantsoeng le litsamaiso tsa ho hloekisa mafura li ka hlalosoa ho theha mokoallo o batlang o sa kenellehe.
4. Ho Sebetsa Tikolohong e Ikgethang
Li-bearings tsa Vacuum le Cleanroom: Sebelisa litšepe tse ntšoang khase le li-lubricant tse khethehileng tse omileng (mohlala, silevera, khauta, kapa lipente tsa MoS2) kapa li etselitsoe ho sebetsa li sa tlotsoa ka likarolo tsa ceramic ho thibela ho tsoa ha khase.
Li-Bearings tse seng tsa Magnetic: Lia hlokahala mechineng ea MRI le lisebelisoa tse nepahetseng. Tsena li entsoe ka litšepe tse sa hloekang tsa austenitic (AISI 304) kapa li-ceramics, ho netefatsa hore ha ho na tšitiso ea makenete.
Tlhahisoleseling ea Tšebeliso: Moo Li-Bearings tse Feteletseng li Pakang Bohlokoa ba Tsona
Ho Sebetsa Lijo le Lino: Li-bearing tse 316 tsa tšepe e sa hloekang tse tebileng tse nang le litlolo tse lumelloang ke FDA li mamella ho hlatsuoa ha metsi ka khatello e phahameng letsatsi le letsatsi ka li-cleaner tsa caustic.
Merafo le ho Cheka: Li-bering tse nang le litiiso tse boima haholo le lipente tsa tungsten carbide lia phela ka har'a lipompo tsa slurry le li-crusher tse tletseng seretse se khorofo.
Li-Actuator tsa Sefofane: Li-bearing tse bobebe, tse lumellanang le vacuum li netefatsa ts'ebetso e tšepahalang mochesong o feteletseng le ho fetoha ha khatello ha sefofane se fofa.
Qetello: Pere ea Mosebetsi e Ikamahanyang le Maemo
Ho bea bolo e tebileng ea mokoti ho paka hore moralo o utloahalang ka ho feletseng o ka fetoloa hore o atlehe hoo e ka bang kae kapa kae. Ka ho khetha thepa ka bohlale, mafura, litiiso le mekhoa ea ho futhumatsa, baenjiniere ba ka totobatsa ho bea bolo e tebileng eo e seng e le karolo e tloaelehileng feela, empa e le tharollo e entsoeng ka mokhoa o ikhethileng bakeng sa ho phela. Ho ikamahanya le maemo hona ho netefatsa hore esita le maemong a thata ka ho fetisisa a polanete, melao-motheo ea ho potoloha ho boreleli le ho tšepahalang e ka tšoarella. Ho totobatsa ho bea bolo e nepahetseng ea tikoloho e feteletseng ha se litšenyehelo tse ling - ke letsete ho nako e tiisitsoeng ea ho sebetsa le katleho ea thomo.
