I-skeleton oil seal imele uphawu lukawoyela ojwayelekile, kanti igama elijwayelekile elithi oil seal libhekisa ku-skeleton oil seal.Indima yophawu lwamafutha wukuhlukanisa izingxenye zokudlulisela ezidinga ukugcotshwa endaweni yangaphandle, ukuze i-lubricant ingaphumi.Uhlaka lwamathambo lufana nokuqiniswa ngaphakathi kwelungu likakhonkolo, elidlala indima yokuqinisa nokwenza uphawu lukawoyela lukwazi ukugcina ukuma nokushuba kwalo.Ngokwefomu lesakhiwo, kukhona i-single skeleton oil seal kanye ne-double skeleton oil seal.Udebe lwesibili lwe-double-lip skeleton oil seal ludlala indima yokuvikela uthuli ukuvimbela uthuli nokungcola ukuthi kungangeni emshinini.Ngokohlobo lohlaka lwamathambo, lungahlukaniswa lube i-internal skeleton oil seal, i-skeleton oil seal eveziwe kanye nophawu lwamafutha oluhlanganisiwe.Ngokwesimo sokusebenza Ingahlukaniswa nge-rotary skeleton oil seal kanye ne-round-trip skeleton oil seal.Isetshenziselwa injini kaphethiloli crankshaft, diesel injini crankshaft, gearbox, umehluko, shock absorber, injini, i-ekseli nezinye izingxenye.
Isakhiwo se-skeleton oil seal sinezingxenye ezintathu: umzimba we-oil seal, uhlaka lwamathambo oluqinisiwe kanye nesiphethu esivunguzayo esiziqinisayo.Umzimba we-seal uhlukaniswe phansi, ukhalo, unqenqema kanye nodebe oluvalayo ngokwezingxenye ezahlukene.Ngokuvamile, ububanzi bangaphakathi be-skeleton oil seal esimweni samahhala buncane kunobubanzi be-shaft, okungukuthi bunenani elithile "lokuphazamiseka".Ngakho-ke, ngemva kokuba uphawu lukawoyela lufakwe esihlalweni sophawu lwamafutha kanye ne-shaft, ukucindezela konqenqema lophawu lwamafutha kanye namandla okufinyezwa kwe-self-tightening spiral spring kukhiqiza amandla athile okuqinisa ama-radial ku-shaft, nangemva kwesikhathi sokusebenza. , ukucindezela kuzokwehla ngokushesha noma ngisho nokunyamalala, ngakho-ke, intwasahlobo ingakhokhela amandla okuziqinisa ophawu lwamafutha nganoma yisiphi isikhathi.
Umgomo wokuvala: Ngenxa yokuba khona kwefilimu kawoyela elawulwa unqenqema lophawu lukawoyela phakathi kwesigxivizo sikawoyela ne-shaft, le filimu kawoyela inezici zokuthambisa uketshezi.Ngaphansi kwesenzo sokuqina kwe-liquid surface, ukuqina kwefilimu kawoyela kwenza ukuphela kokuthintana kwefilimu kawoyela nomoya kube indawo ecwebezelayo, kuvimbele ukuvuza kwemidiya esebenzayo, ngaleyo ndlela kuqaphe ukuvaleka kwe-shaft ejikelezayo.Amandla okuvala uphawu lwamafutha ancike ebukhulu befilimu yamafutha endaweni yokuvala.Uma ubukhulu bukhulu kakhulu, uphawu lwamafutha luzovuza;uma ubukhulu buncane kakhulu, ukungqubuzana okomile kungase kwenzeke, okubangela ukugqoka kwe-oil seal kanye ne-shaft;uma kungekho ifilimu yamafutha phakathi komlomo wokuvala kanye ne-shaft, kuzokwenza kalula ukushisa nokugqoka.
Ngakho-ke, ngesikhathi sokufakwa, uwoyela othile kufanele usetshenziswe eringini yophawu ngenkathi uqinisekisa ukuthi uphawu lwamafutha ohlaka lwamathambo luhambisana ne-shaft centerline.Uma kungeyona i-perpendicular, i-seal lip ye-oil seal izokhipha i-lubricant kusuka ku-shaft, okuzophinde kuholele ekugqokeni ngokweqile komlomo we-seal.Lapho isebenza, okokugcoba kugobolondo kuphuma kancane ukuze kufinyelele isimo esihle kakhulu sokwenza ifilimu kawoyela endaweni evalekayo.
Indima ye-skeleton oil seal ngokuvamile iwukuhlukanisa izingxenye zezingxenye zokudlulisela ezidinga ukugcotshwa ezingxenyeni eziphumayo ukuze okokugcoba kungavuzi, futhi kuvame ukusetshenziselwa ama-shafts ajikelezayo, uhlobo lwe-shaft lip seal ejikelezayo.Uhlaka lwamathambo lufana nokuqiniswa ngaphakathi kwelungu likakhonkolo, elidlala indima yokuqinisa nokwenza uphawu lwamafutha lukwazi ukugcina ukuma nokushuba kwalo.Ngokohlobo lohlaka lwamathambo, lungahlukaniswa lube yi-internal skeleton oil seal, i-external skeleton oil seal, i-internal and outside skeleton oil seal.I-Skeleton oil seal yenziwe ngerabha ye-nitrile yekhwalithi ephezulu nepuleti lensimbi, elinekhwalithi ezinzile nempilo ende yesevisi.Isetshenziswa kabanzi ku-automobile, motorcycle crankshaft, camshaft, differential, shock absorber, injini, i-ekseli, amasondo angaphambili nangemuva, njll.
