Ngenxa yobukho befilimu yeoli elawulwa yi-oil seal blade phakathi kweitywina yeolikunye ne-shaft, le filimu yeoli ineempawu zokuthambisa ulwelo.Ngaphantsi kwesenzo soxinzelelo lwe-liquid surface, ukuqina kwefilimu yeoli ngokuchanekileyo kwenza i-crescent surface ekupheleni koqhagamshelwano phakathi kwefilimu yeoli kunye nomoya, ukuthintela ukuvuza kwendawo yokusebenza kunye nokufezekisa ukutywinwa kwe-shaft ejikelezayo.Amandla okutywinwa kwamatywina e-oyile axhomekeke kubukhulu befilimu yeoli kwindawo yokutywina.Ukuba ubukhulu bukhulu kakhulu, isitywina seoli sinokuvuza;Ukuba ubukhulu buncinci kakhulu, ukungqubuzana okomileyo kunokwenzeka, kubangele ukutywinwa kweoli kunye nokugqoka kwe-shaft;Ukuba akukho filimu yeoli phakathi komlomo wokutywina kunye ne-shaft, kulula ukubangela ukufudumeza nokugqoka.
Ngoko ke, ngexesha lofakelo, kuyimfuneko ukusebenzisa ioli ethile kwindandatho yokutywina kwaye uqinisekise ukuba i-oyile ye-skeleton itywina i-perpendicular kwi-axis.Ukuba ayinayo i-perpendicular, umlebe wokutywina wesitywina seoli uya kukhupha ioli yokuthambisa kwi-shaft kwaye ibangele ukugqithiswa komlomo wokutywina.Ngexesha lokusebenza, i-lubricant ngaphakathi kweqokobhe iphuma kancinci ukuze iphumeze eyona meko ifanelekileyo yokwenza ifilimu yeoli kwindawo yokutywinwa.
Phawula:
1. Ukususela ekufumaneni i-oil seal ukuya kwindibano, kufuneka igcinwe icocekile.
2. Ngaphambi kokuhlanganisana, yenza uhlolo lwe-oyile kwaye ulinganise ukuba imilinganiselo yenxalenye nganye ye-oyile ye-skeleton ihambelana nemilinganiselo ye-shaft kunye ne-cavity.Ngaphambi kokufaka i-oyile ye-oyile ye-skeleton, thelekisa ububanzi be-shaft kunye nobubanzi obungaphakathi be-oil seal ukuqinisekisa ukuhambelana.Ubungakanani obungaphakathi kwicavity kufuneka bufaneleke kububanzi obungaphandle bobubanzi betywina leoli.Khangela ukuba umlebe we-oyile ye-skeleton seal yonakele okanye ikhubazekile, kwaye ingaba i-spring ivaliwe okanye i-rust.Thintela isitywina se-oyile ekubeni sibekwe sicaba ngexesha lothutho, kunye nokuchatshazelwa ngamandla angaphandle anje ngoxinzelelo kunye neempembelelo, ezinokonakalisa ukujikeleza kwayo kokwenyani.
3. Ngaphambi kokuhlanganisana, yenza inkqubo yokuhlola i-machining kwaye ulinganise ukuba imilinganiselo ye-cavity kunye ne-shaft ichanekile, ngakumbi i-chamfer yangaphakathi, akufanele ibe ne-slope.Ubuso besiphelo se-shaft kunye ne-cavity kufuneka zenziwe ngokucokisekileyo, kwaye i-chamfer kufuneka ingabi namonakalo kunye ne-burrs.Coca indawo yokudibanisa, kwaye akufanele kubekho i-burrs, isanti, iifayili zetsimbi okanye ezinye i-debris ekufakeni (i-chamfer) ye-shaft, enokubangela umonakalo ongaqhelekanga kwi-oil seal lip.Kunconywa ukusebenzisa i-R-angle yendawo ye-chamfer.
4. Ngokubhekiselele kwizakhono zokusebenza, unokuziva ngezandla zakho ukuba zigudile kwaye zijikeleze ngokwenene.
5. Ngaphambi kokufaka i-skeleton oil seal, musa ukukrazula iphepha lokupakisha ngokukhawuleza ukukhusela i-debris ekubambeleleni kumphezulu we-oyile kunye nokungena emsebenzini.
6. Ngaphambi kokufakela, i-oyile ye-skeleton kufuneka ifakwe ngokufanelekileyo nge-lithium ester equkethe i-molybdenum disulfide phakathi kwemilebe yokuthintela ukugquma okomileyo emlonyeni xa i-shaft iqala ngokukhawuleza, echaphazela ukuphazamisa ubungakanani bomlomo.Indibano ifanele iqhutywe ngokukhawuleza.Ukuba isihlalo sokutywinwa kweoli asifakwanga ngokukhawuleza, kucetyiswa ukuba usigubungele ngendwangu yokukhusela izinto zangaphandle ukuba zibambelele kwisitywina seoli.Izandla okanye izixhobo ezisetyenziselwa ukufaka igrisi ye-lithium kufuneka zicoceke.
7. I-oyile ye-skeleton seal kufuneka ifakwe i-flat kwaye kungabikho nto i-tilting.Kunconywa ukusebenzisa izixhobo ze-hydraulic okanye izixhobo ze-sleeve zofakelo.Musa ukubeka uxinzelelo olukhulu, isantya kufuneka silingane kwaye sicothe.
8. Phawula umatshini oxhotyiswe nge-oyile ye-skeleton ngeenjongo zokulandela umkhondo kwaye ubeke ingqalelo ngokukhawuleza kuyo yonke inkqubo.
