Isitywina se-oyile samathambo ngummeli oqhelekileyo wokutywinwa kweoyile, kwaye igama eliqhelekileyo lokutywinwa kweoyile libhekisa kwisitywina seoyile samathambo.Indima yesitywina seoli kukuhlukanisa iindawo zothumelo ezifuna i-lubrication kwindawo yangaphandle, ukwenzela ukuba i-lubricant ingaphumi.I-skeleton ifana nokuqiniswa ngaphakathi kwelungu lekhonkrithi, elidlala indima yokomeleza kwaye yenza ukuba i-oyile itywinwe igcine imilo kunye noxinzelelo.Ngokwefomu yesakhiwo, kukho i-oyile yomlomo omnye wamathambo kunye ne-double skeleton oil seal.Umlebe wesibini we-double-lip skeleton oil seal udlala indima yokuthintela uthuli ukukhusela uthuli kunye nokungcola ekungeneni kumatshini.Ngokohlobo lwamathambo, lunokwahlulwa lube lutywino lwangaphakathi lwamathambo e-oyile, i-oyile ye-oyile eveziweyo kunye nokutywinwa kweoyile.Ngokwemeko yokusebenza Inokwahlulwa ibe yi-rotary skeleton oil seal kunye nokujikeleza-uhambo olujikelezayo lwe-oyile ye-skeleton.Isetyenziselwa i-crankshaft ye-injini yepetroli, i-crankshaft ye-injini ye-diesel, i-gearbox, i-differial, i-absorber, i-injini, i-asi kunye nezinye iindawo.
Ulwakhiwo lwe-oyile ye-Skeleton lunamacandelo amathathu: umzimba we-oyile, i-skeleton eyomeleziweyo kunye ne-self-tightening spiral spring.Umzimba wetywina wahlulwe waba ngasezantsi, esinqeni, emphethweni kunye nomlebe wokutywina ngokwamalungu ahlukeneyo.Ngokuqhelekileyo, i-diameter yangaphakathi ye-skeleton oil seal kwi-free state incinci kune-shaft diameter, oko kukuthi, inomlinganiselo othile "wokuphazamiseka".Ke ngoko, emva kokuba uphawu lweoyile lufakwe kwisihlalo sokutywinwa kwe-oyile kunye ne-shaft, uxinzelelo lomphetho we-oyile yokutywina kunye namandla okucutheka kwe-self-tightening spiral spring ivelisa amandla athile okuqinisa i-radial kwi-shaft, kwaye emva kwexesha lokusebenza. , uxinzelelo luya kuncipha ngokukhawuleza okanye lude luphele, ngoko ke, intwasahlobo inokuhlawulela amandla okuqinisa i-oil seal nangaliphi na ixesha.
Umgaqo wokutywina: Ngenxa yobukho befilimu yeoli elawulwa sisitywina se-oyile phakathi kwesitywina se-oyile kunye ne-shaft, le filimu yeoli ineempawu zokuthambisa ulwelo.Ngaphantsi kwesenzo soxinzelelo lwe-liquid surface, ukuqina kwefilimu yeoli kwenza ukuba isiphelo soqhagamshelwano sefilimu ye-oyile kunye nomoya senze i-crescent surface, ukukhusela ukuvuza kweendaba ezisebenzayo, ngaloo ndlela ukuqonda ukutywinwa kwe-shaft ejikelezayo.Umthamo wokutywinwa kweoli yeoli ixhomekeke kubukhulu befilimu yeoli kwindawo yokutywina.Ukuba ubukhulu bukhulu kakhulu, uphawu lweoyile luya kuvuza;ukuba ubukhulu buncinci kakhulu, ukungqubuzana okomileyo kunokwenzeka, kubangele ukugqoka kwe-oyile kunye ne-shaft;ukuba akukho filimu yeoli phakathi komlomo wokutywina kunye ne-shaft, iya kubangela lula ukushisa kunye nokugqoka.
Ngoko ke, ngexesha lofakelo, enye ioli kufuneka ifakwe kwindandatho yokutywina ngelixa iqinisekisa ukuba i-oyile ye-skeleton ye-oyile i-perpendicular kwi-shaft centerline.Ukuba ayinayo i-perpendicular, i-seal lip yesitywina seoli iya kukhupha i-lubricant kwi-shaft, eya kukhokelela ekugqithiseni ngokugqithiseleyo komlomo wokutywina.Ukusebenza, i-lubricant kwiqokobhe iphuma kancinci ukufezekisa eyona meko ifanelekileyo yokwenza ifilimu yeoli kwindawo yokutywinwa.
Indima ye-oyile ye-skeleton ye-oyile ngokuqhelekileyo kukwahlula iinxalenye zamacandelo othumelo afuna i-lubrication kwiindawo eziphumayo ukuze i-lubricant ingavuzi, kwaye ngokuqhelekileyo isetyenziselwa ukujikeleza i-shafts, uhlobo olujikelezayo lwe-shaft lip seal.I-skeleton ifana nokuqiniswa ngaphakathi kwelungu lekhonkrithi, elidlala indima yokomeleza kwaye yenza ukuba i-oyile itywinwe igcine imilo kunye noxinzelelo.Ngokohlobo lwamathambo, lunokwahlulwa lube lutywino lwangaphakathi lwamathambo e-oyile, itywina langaphandle le-oyile ye-skeleton, i-oyile yangaphakathi nangaphandle eveziweyo.I-Skeleton oil seal yenziwe ngerabha ye-nitrile ekumgangatho ophezulu kunye nepleyiti yentsimbi, enomgangatho ozinzile kunye nobomi benkonzo ende.Isetyenziswa kakhulu kwimoto, isithuthuthu crankshaft, camshaft, umahluko, ukothuka, injini, iasi, amavili ngaphambili nangasemva, njl.
1. Thintela udaka, uthuli, ukufuma, njl njl. ekungeneni kwiibheringi ezivela ngaphandle.
2. Nciphisa ukuvuza kweoyile yokuthambisa kwibheringi.Iimfuno zokutywinwa kweoli kukuba ubukhulu (ububanzi bangaphakathi, ububanzi bangaphandle kunye nobukhulu) kufuneka buhambelane nemimiselo;kuyadingeka ukuba ube ne-elasticity efanelekileyo, enokuthi idibanise i-shaft ngokufanelekileyo kwaye idlale indima yokutywina;kufuneka ikwazi ukumelana nobushushu, inxibe, amandla afanelekileyo, ukumelana nokuphakathi (ioli okanye amanzi, njl.) kunye nobomi benkonzo ende.
Ukusebenzisa i-oil seal ngokufanelekileyo, kufuneka kuqatshelwe la manqaku alandelayo.
(1) Isantya se-Shaft Ngenxa yoyilo kunye nesakhiwo, i-oyile yokutywinwa kwesantya esiphezulu kufuneka isetyenziswe kwi-shaft yesantya esiphezulu kunye nesantya esisezantsi se-oyile yokutywinwa kwe-shaft ye-shaft ephantsi, kunye ne-oyile yokutywinwa kwe-oyile ephantsi ayinakusetyenziswa kwi-shaft ye-high speed shaft kwaye ngokuphambene noko.
(2) Ubushushu be-Ambient kwimeko yokusetyenziswa okuphezulu kobushushu, i-polypropylene ester okanye i-silicon, i-fluorine, irabha ye-silicone fluorine kufuneka ikhethwe.Kwaye kufuneka uzame ukunciphisa ubushushu be-oyile kwitanki yeoli.Kwimeko yokusebenzisa iqondo lobushushu liphantsi kakhulu, kufuneka ukhethe ukusebenzisa irabha ekwazi ukumelana nokubanda.
(3) Uxinzelelo Jikelele lwe-oyile itywina inamandla okumelana noxinzelelo, kwaye isitywina se-oyile siyakonakala xa uxinzelelo lukhulu kakhulu.Ngaphantsi kwemeko yokusetyenziswa koxinzelelo olugqithisileyo, i-ring-resistant-resistant support ring okanye i-oil seal eyomeleziweyo kufuneka isetyenziswe.
(4) I-Eccentricity degree ekufakeni Ukuba i-eccentricity ye-oil seal kunye neshafti inkulu kakhulu, isitywina siya kuba mbi, ngakumbi xa isantya se-shaft siphezulu.Ukuba i-eccentricity inkulu kakhulu, i-oil seal enecandelo elithi "W" ingasetyenziswa.
(5) Ukugqitywa komphezulu we-shaft kuchaphazela ngokuthe ngqo ubomi benkonzo yesitywina seoli, oko kukuthi, ukuba i-shaft finish iphezulu, ubomi benkonzo yesitywina seoli buya kuba bude.
(6) Nikela ingqalelo kwisixa esithile sesithambiso kumlebe wetywina leoli.
(7) Nika ingqalelo ekhethekileyo ukuthintela uthuli ukuba lungatshoni kwisitywina seoli. Isilumkiso:
Isilumkiso:
1. Thatha inani elimiselweyo lamatywina oyile.
2. Ukususela ekuqokeleleni uphawu lweoli ukuya kwindibano, kufuneka igcinwe icocekile.
3. Ngaphambi kokudibanisa, yenza uhlolo olufanelekileyo lwesitywina seoli, ulinganise ukuba ubungakanani benxalenye nganye ye-oyile ye-skeleton ihambelana nobukhulu be-shaft kunye ne-cavity.Phambi kokufaka i-oyile ye-oyile, jonga ubungakanani bedayamitha ye-shaft ngokuchasene nobukhulu bangaphakathi be-oyile yetywina ngokucacileyo ukuze ihambelane.Ubungakanani bombhobho kufuneka buhambelane nobubanzi bobubanzi obungaphandle kwesitywina seoli.Jonga ukuba umlebe we-oyile ye-skeleton yonakele okanye ukhubazekile, kwaye ingaba umthombo ucimile okanye urulile.Thintela isitywina se-oyile ekubeni sibekwe sicaba ngexesha lothutho kunye nokuchatshazelwa ngamandla angaphandle afana nokukhupha kunye neempembelelo, kwaye utshabalalise ukujikeleza kwayo kokwenyani.
4. Yenza inkqubo yokuhlola i-machining elungileyo ngaphambi kokuhlanganisana, linganisa ukuba ubungakanani bomgodi kunye neengxenye ze-shaft zichanekile, ngakumbi i-chamfer yangaphakathi, akunakubakho ithambeka, isiphelo sobuso be-shaft kunye ne-cavity kufuneka siqhutywe kakuhle, akukho monakalo. kunye ne-burr kwi-chamfer, ihlambulule iindawo zendibano, akunakubakho burr, isanti, iitshiphu zentsimbi kunye nolunye udoti kwindawo yokulayisha (i-chamfer) inxalenye ye-shaft, eya kuvelisa umonakalo ongaqhelekanga kumlomo we-oil seal, kucetyiswa ukuba usebenzise i-engile kwi-chamfering part.
5. Kwindlela yokusebenza, unokuziva ngesandla sakho ukuba sigudile kwaye singqukuva ngenene.
6. Musa ukukrazula iphepha lokusonga kwangoko ngaphambi kokufaka i-oyile ye-skeleton ukukhusela i-debris ekunamatheleni kumphezulu we-oyile kunye nokuzisa emsebenzini.
7. Ngaphambi kokufakela, i-oyile ye-skeleton kufuneka ifakwe i-lithium ester kunye ne-molybdenum disulfide eyongeziweyo kwixabiso elifanelekileyo phakathi komlomo ukukhusela i-shaft ekubangeleni into eyomileyo yokugaya emlonyeni xa iqala ngokukhawuleza kwaye ichaphazela ubuninzi bokugqithisa umlomo, kwaye kufuneka zihlanganiswe ngokukhawuleza.Isihlalo sokutywinwa kweoli kunye ne-oil seal efakwe, ukuba ayifakwanga ngokukhawuleza, kucetyiswa ukuba igubungele ngendwangu yokukhusela into yangaphandle ukuba ifakwe kwisitywina seoli.Isandla okanye isixhobo sokusebenzisa igrisi ye-lithium kufuneka sicoceke.
8. I-oyile ye-skeleton seal kufuneka ifakwe i-flat, akukho nto i-tilting.Kucetyiswa ukuba kusetyenziswe izixhobo zoxinzelelo lweoyile okanye isixhobo somkhono ukufaka.Uxinzelelo akufunekanga lube lukhulu kakhulu, kwaye isantya kufuneka silingane kwaye sicothe.
9. Kumatshini apho i-oyile ye-skeleton ifakwe khona, phawula ukuba uququzelele ukulandelela kwaye ubeke ingqalelo kuyo yonke inkqubo.
