Ukwakhiwa kophawu lwamafutha
Izigxivizo zamafutha ngokuvamile zihlukaniswa ngohlobo olulodwa kanye nohlobo lokuhlanganisa.
Uhlobo oluhlanganisiwe luhlaka kanye nezinto zomlomo zingahlanganiswa ngokukhululekile, ngokuvamile zisetshenziselwa izimpawu ezikhethekile zamafutha.
Uwoyela uphawu kanye isicelo
3.1.1 Isigxivizo sikawoyela
Uphawu lwamafutha luwuphawu lwamafutha okugcoba.Umsebenzi wawo ukuhlukanisa i-oil chamber ezweni langaphandle, ukuvala uwoyela ngaphakathi nokuvimbela uthuli ngaphandle.Izigxivizo zikawoyela zisetshenziswa kakhulu ukuvalwa kokudluliswa kwezimoto kanye nama-hub bearings.
(1) Izici nemingcele yezobuchwepheshe yophawu lwamafutha
Umehluko phakathi kwe-oil seal nezinye izindebe zomlomo ukuthi unodebe olunokuqina okukhulu, ububanzi bendawo yokuxhumana yokuvala buncane kakhulu (cishe u-0.5mm), futhi iphethini yokusabalalisa yokucindezeleka kokuxhumana ikhonjiwe.Umfanekiso ubonisa ukwakheka okujwayelekile kophawu lwamafutha kanye nomdwebo wohlelo lokucindezeleka komlomo wodebe.Ukuma kwe-cross-sectional ye-oil seal kanye ne-clamping spring kwenza udebe lube nesinxephezelo esingcono sokulandelela shaft.Ngakho-ke, uphawu lukawoyela lungathola umphumela wokuvala ongcono ngamandla amancane emisebe yomlomo.
Umdwebo. Isakhiwo esijwayelekile se-oil seal kanye ne-schematic diagram ye-lip contact stress
1-udebe;2-umqhele;I-3-spring: 4-skeleton;5-phansi: 6-ukhalo;7-accessory lip
Uma kuqhathaniswa nezinye izinto zokuvala, uphawu lwamafutha lunezinzuzo ezilandelayo.
①Isakhiwo silula futhi kulula ukusikhiqiza.Izimpawu zamafutha ezilula zingabunjwa ngesikhathi esisodwa, futhi ngisho nezimpawu zamafutha eziyinkimbinkimbi kakhulu zinenqubo yokukhiqiza enzima.I-metal skeleton oil seal ingabuye yakhiwe ngensimbi nerabha ukwenza uphawu lwamafutha oludingekayo ngokusebenzisa isitembu, i-gluing, inlaying, ukubumba nezinye izinqubo.
②Isisindo esincane kanye nezinto ezincane ezidlekayo.Uphawu lwamafutha ngalunye luyinhlanganisela yezingxenye zensimbi ezinodonga oluncane nezingxenye zenjoloba, futhi ukusetshenziswa kwayo kwempahla kuncane kakhulu, ngakho uphawu lwamafutha ngalunye lulula kakhulu ngesisindo.
③ Isikhundla sokufakwa kophawu lwamafutha sincane, ubukhulu be-axial buncane, kulula ukucubungula, futhi isakhiwo somshini sihlangene.
④ Ukusebenza kahle kokuvala nempilo ende yesevisi.Inokuvumelana okuthile nokudlidliza komshini kanye nokugqama kwe-shaft eyinhloko.
⑤Ukuqaqa nokulungisa kalula.
⑥Intengo ishibhile.
Ububi be-oil seal ukuthi ayikwazi ukumelana nokucindezela okuphezulu, ngakho-ke ingasetshenziswa kuphela njengophawu lokuthwala amafutha okugcoba.
Uhlu olusebenzayo lophawu lwamafutha: ingcindezi yokusebenza imayelana ne-0.3MPa;isivinini somugqa wendawo yokuvala singaphansi kuka-4m/s, futhi uhlobo lwejubane luyi-4 ~ 15m/s;izinga lokushisa elisebenzayo lingu-60 ~ 150 ° C (elihlobene nohlobo lwerabha);okusebenzayo Indlela esetshenziswayo uwoyela, amanzi kanye noketshezi oludlayo olubuthaka;impilo yesevisi ingu-500 ~ 2000h.
(2) Isakhiwo sophawu lwamafutha
Isakhiwo sophawu lwamafutha esivamile siboniswa emfanekisweni
Umfanekiso |Isakhiwo sezimpawu zamafutha ezivamile
① Isakhiwo esihlanganisiwe Isici salesi sakhiwo ukuthi ingxenye yerabha kanye nohlaka lwamathambo ensimbi kungacutshungulwa futhi kwenziwe ngokuhlukana, bese kuhlanganiswe neglu ukuze kwakhe uhlobo lohlaka lwamathambo oluveziwe, olunobuhle bokwenziwa okulula kanye nenani eliphansi.Amazwe anjenge-United States ne-Japan ngokuvamile amukela lesi sakhiwo.Umumo wabo wezigaba ezihlukene ukhonjiswe kuMfanekiso (a).
②Isakhiwo se-Assembly Ukuhlanganisa udebe lwenjoloba, uhlaka lwensimbi kanye nendandatho yasentwasahlobo ukuze kwakhiwe uphawu lwamafutha.Kumele ibe nohlaka lwamathambo olungaphakathi nangaphandle, futhi ibambe udebe lwenjoloba.Ngokuvamile kuba khona ukudideka ukuvimbela isiphethu ukuthi singaphumi [Umfanekiso (b)].
③Isakhiwo sesikelethoni esigoqwe ngerabha.Isonga uhlaka lwamathambo ensimbi olugxotshiwe ngerabha ukwenza uhlobo lwamathambo angaphakathi.Inqubo yayo yokukhiqiza iyinkimbinkimbi kancane, kodwa inokuqina okuhle futhi kulula ukuyihlanganisa, futhi ayinazo izidingo eziphakeme zezinto zepuleti lensimbi [Figure ( c)].
④ Isigxivizo samafutha enjoloba egcwele Lolu hlobo lwamafutha alunawo uhlaka lwamathambo, amanye awanaso isiphethu, futhi wonke abunjwa ngenjoloba.Ibonakala ngokuqina okungalungile futhi ijwayele ukuguqulwa kwepulasitiki.Kodwa ingasetshenziswa nama-cutouts, okuwukuphela kwefomu lezingxenye ezingakwazi ukufakwa kusukela ekugcineni kwe-shaft kodwa kufanele zivalwe ngamafutha [Fig.(d)].
(3) Izigxivizo zikawoyela zezimoto
I-Rotary shaft lip seal ngokuvamile ibizwa ngokuthi ama-oil seal.Ngokusho kwesakhiwo, izimpawu zikawoyela zihlukaniswe zibe izigxivizo zamafutha zohlaka lwangaphakathi, kufaka phakathi uhlobo lwe-B (ngaphandle kwezindebe ezisizayo) kanye nohlobo lwe-FB (enezindebe ezisizayo) izigxivizo zamafutha;izigxivizo zamafutha zamathambo eziveziwe, kufaka phakathi uhlobo lwe-W (ngaphandle kwezindebe ezisizayo) kanye nohlobo lwe-FB (enezindebe ezisizayo);umhlangano Thayipha uphawu lwamafutha, kufaka phakathi uhlobo lwe-B (ngaphandle komlomo osizayo) bese uthayipha i-FZ (enezindebe ezisizayo).Isakhiwo se-oil seal sinethonya elikhulu ekusebenzeni kwalo.Ngeminyaka yawo-1970 kanye nawo-1980, ngocwaningo olujulile mayelana nesakhiwo sophawu lukawoyela (umumo wesigaba nosayizi), uchungechunge lwamadivayisi okubona ahlobene nokwakheka kwesakhiwo (njengamandla e-oil seal radial force, ububanzi bokuthinta izindebe, ukungqubuzana kwezindebe, izinga lokushisa kwezindebe) zathuthukiswa.ilitha kanye nensimbi yokuhlola impilo noma ibhentshi), ukubeka isisekelo somklamo wesakhiwo sophawu lukawoyela .Izimiso zokuklama imingcele yesakhiwo sesigxivizo sikawoyela (umumo nosayizi wokhalo, usayizi omeshayo wodebe nomthombo wespring, inani lokuphazanyiswa, umumo nosayizi we i-axiliary lip, njll.) ye-oil seal inqunywa ngokuyisisekelo.Lezi zimiso zisetshenziswe kumazinga wokwakhiwa kophawu lwamafutha GB 987711, GB 987712 kanye ne-GB 987713.
Uma kuqhathaniswa nophawu lwamafutha ohlaka lwangaphakathi, uphawu lwamafutha ozimele oluveziwe lune-coaxiality ephezulu yokufaka kanye nomphumela wokuvala ongcono, kodwa kunzima kakhulu ukulawula ubuchwepheshe bokucubungula kanye nokunemba kwe-dimensional kwesikhunta nokugaya umkhiqizo.Izigxivizo zikawoyela wezimoto zakwamanye amazwe ziyizimpawu zikawoyela zamathambo, kanti izigxivizo zikawoyela wezimoto zasekhaya ziyizimpawu zikawoyela zamathambo angaphakathi.Ekuqaleni kwawo-1980, uMnyango Wemboni Yamakhemikhali wangaphambili wahlela ucwaningo olukhulu mayelana nokuthuthukiswa kwezigxivizo zikawoyela zamathambo, okuhlanganisa isilinganiso sefomula nesakhiwo sophawu lwamafutha ohlaka lwamathambo, ukuhlangana kwerabha kanye nohlaka lwamathambo, i-antirust. ukwelashwa kwe-skeleton eveziwe, umklamo wentwasahlobo kanye nesikhunta kanye Nokucutshungulwa, ubuchwepheshe bokugaya umkhiqizo, njll. Kuye kwafundwa ngokuhlelekile, kodwa ngenxa yezizathu ezihlukahlukene, izwe lami alikakafinyeleli ukukhiqizwa okukhulu kwezimpawu zamafutha zamathambo eziveziwe.
