Oil chisimbiso chimiro
Oiri zvisimbiso zvinowanzo patsanurwa kuita imwe mhando uye rudzi rwegungano.
Yakasanganiswa mhando ndiyo furemu uye zvinhu zvemuromo zvinogona kusanganiswa zvakasununguka, zvinowanzo shandiswa kune yakakosha zvisimbiso zvemafuta.
Oil chisimbiso uye kushandiswa
3.1.1 Chisimbiso chemafuta
Chisimbiso chemafuta ndicho chisimbiso chemafuta ekuzora.Basa rayo nderekuparadzanisa kamuri yemafuta kubva kunze kwenyika, kuvhara mafuta mukati uye kudzivirira guruva kunze.Oiri zvisimbiso zvinonyanya kushandiswa kuvharika kwekufambiswa kwemotokari uye hub bearings.
(1) Hunhu uye tekinoroji ma parameter echisimbiso chemafuta
Musiyano uripo pakati pechisimbiso chemafuta uye zvimwe zvisimbiso zvemiromo ndewekuti ine muromo ine kusimba kukuru, hupamhi hwechisimbiso chekubata kumeso hwakatetepa kwazvo (anenge 0.5mm), uye nzira yekugovera yekushushikana kwekusangana inonongedza.Mufananidzo unoratidza chimiro chakajairwa chechisimbiso chemafuta uye dhizaini yedhizaini yekusangana kushushikana kwemuromo.Iyo muchinjika-chikamu chimiro chechisimbiso chemafuta uye chitubu chinosungirira chinoita kuti muromo uve nani wekutevera muripo we shaft.Naizvozvo, iyo chisimbiso chemafuta inogona kuwana irinani yekuisa chisimbiso nediki muromo radial simba.
Fig. Chimiro chechimiro chemafuta chisimbiso uye schematic diagram yemuromo wekubata kushushikana
1-muromo;2-korona;3-spring: 4-skeleton;5-pasi: 6-chiuno;7-yekuwedzera muromo
Kuenzaniswa nemamwe maturusi ekuvharisa, chisimbiso chemafuta chine zvinotevera zvakanakira.
①Chimiro chiri nyore uye chiri nyore kugadzira.Zvisimbiso zvemafuta zvakapfava zvinogona kuumbwa panguva imwe chete, uye kunyange zvisimbiso zvemafuta zvakaomarara zvine maitiro asina kuoma ekugadzira.Iyo simbi skeleton mafuta chisimbiso inogona zvakare kuumbwa nesimbi uye rabha kuti igadzire inodiwa chisimbiso chemafuta kuburikidza nekutsika, gluing, inlaying, kuumba uye mamwe maitiro.
②Huremu huremu uye zvishoma zvinodyiwa.Chisimbiso chemafuta chega chega musanganiswa wesimbi dzakatetepa-madziro uye zvikamu zverabha, uye kushandiswa kwayo kwezvinhu kudiki kwazvo, saka chisimbiso chega chega chemafuta chine huremu hwakanyanya.
③ Nzvimbo yekuisa yechisimbiso chemafuta idiki, iyo axial dimension idiki, iri nyore kugadzirisa, uye chimiro chemuchina chakabatana.
④ Kuita kwakanaka kwekuisa chisimbiso uye hupenyu hurefu hwebasa.Iyo ine kumwe kuchinjika kune vibration yemuchina uye eccentricity yeiyo main shaft.
⑤Kubvisa nyore nyore uye kugadzirisa.
⑥Mutengo wakachipa.
Kukanganisa kwechisimbiso chemafuta ndechekuti haigone kumira kumanikidza kwakanyanya, saka inogona kungoshandiswa sechisimbiso chekutakura mafuta ekuzora.
Kushanda kwechisimbiso chechisimbiso chemafuta: kushanda kwekushanda kunenge 0.3MPa;mutsara wekumhanya kwenzvimbo yekuisa chisimbiso iri pasi pe4m / s, uye rudzi rwekumhanya ndeye 4 ~ 15m / s;kutonhora kwekushanda -60 ~ 150 ° C (yakabatana nemhando yerubha);inoshanda Iyo yepakati imafuta, mvura uye isina kusimba inoodza mvura;hupenyu hwesevhisi ndeye 500 ~ 2000h.
(2) Oiri chisimbiso chimiro
Iyo yakajairika chisimbiso chemafuta chimiro chinoratidzwa mumufananidzo
Mufananidzo |Chimiro chezvisimbiso zvakajairika zvemafuta
① Bonded chimiro Hunhu hweichi chimiro ndechekuti chikamu cherabha uye simbi skeleton inogona kugadzirwa uye kugadzirwa zvakasiyana, yobva yasungwa pamwe chete neglue kuti iite yakafumurwa skeleton mhando, ine zvakanakira kugadzirwa kwakapusa uye mutengo wakaderera.Nyika dzakaita seUnited States neJapan dzinowanzotora chimiro ichi.Maumbirwo avo emuchinjika-chikamu anoratidzwa muMufananidzo (a).
②Assembly chimiro Iko kuunganidza muromo werabha, simbi furemu uye mhete yechirimo kuti igadzire chisimbiso chemafuta.Inofanirwa kunge iine skeleton yemukati nekunze, uye kusungirira muromo werabha.Panowanzoita kuvhiringika kudzivirira chitubu kubuda [Mufananidzo (b)].
③Rabha-yakaputirwa skeleton chimiro.Inoputira skeleton yesimbi yakaroverwa murabha kuti iite yemukati skeleton mhando.Kugadzira kwayo kwakaoma zvishoma, asi ine yakanaka kuomarara uye iri nyore kuunganidza, uye haina zvakakwirira zvinodiwa zvesimbi plate zvinhu [Mufananidzo (c)].
④ Yakazara rubber oiri chisimbiso Iri rudzi rwechisimbiso chemafuta harina skeleton, mamwe haana kana chitubu, uye yese inoumbwa nerabha.Iyo inoratidzirwa nekuomarara kwakashata uye inoenderana nepurasitiki deformation.Asi inogona kushandiswa ne cutouts, inova ndiyo chete fomu yezvikamu zvisingakwanisi kuiswa kubva kumucheto we shaft asi inofanira kuiswa chisimbiso nemafuta [Fig.(d)].
(3) Oiri zvidhindo zvemotokari
Rotary shaft lip seals inowanzonzi mafuta seals.Zvinoenderana nechimiro, zvisimbiso zveoiri zvakakamurwa kuita mukati memafuta zvisimbiso zvemukati, zvinosanganisira B mhando (isina muromo unobatsira) uye FB mhando (ine yekubatsira muromo) zvisimbiso zvemafuta;akafumura skeleton mafuta zvisimbiso, kusanganisira W mhando (isina muromo wekubatsira) uye FB mhando (ine yekubatsira muromo);musangano Rudzi rwechisimbiso chemafuta, kusanganisira mhando B (isina muromo unobatsira) uye nyora FZ (ine muromo unobatsira).Chimiro chechisimbiso chemafuta chine simba guru pakuita kwayo.Mumakore ekuma1970 nema1980, kuburikidza nekutsvaga kwakadzama pamusoro pechimiro chechisimbiso chemafuta (chikamu chechimiro uye saizi), nhevedzano yemidziyo yekuona ine chekuita nekugadzirwa kwechimiro (semafuta seal seal radial force, lip contact wide, friction torsion, tembiricha yemuromo) dzakagadzirwa.litre uye life test instrument kana bhenji), kuisa hwaro hwekugadzirwa kwemafuta seal structure .Magadzirirwo emisimboti yemafuta seal structural parameters (maumbirwo uye saizi yechiuno, saizi inofananidzwa yemuromo uye spring groove, kupindira huwandu, chimiro uye saizi ye muromo wekubatsira, nezvimwewo) zvechisimbiso chemafuta zvakatemwa.Aya misimboti akashandiswa mumafuta chisimbiso dhizaini zviyero GB 987711, GB 987712 uye GB 987713.
Kuenzaniswa neyemukati furemu yemafuta chisimbiso, iyo yakafumurwa furemu chisimbiso chemafuta ine yakakwirira yekumisikidza coaxiality uye iri nani yekuisa chisimbiso mhedzisiro, asi zvakanyanya kuoma kudzora tekinoroji yekugadzira uye dimensional kurongeka kwe mold uye chigadzirwa kukuya.Zvisimbiso zvemafuta emotokari ekunze zvinonyanya kufumurwa skeleton mafuta zvisimbiso, nepo zvisimbiso zvemota dzemotokari zvinonyanya kunyanya skeleton mafuta zvisimbiso.Mukutanga kwema1980, yaimbova Ministry of Chemical Indasitiri yakaronga tsvakiridzo yakakura pamusoro pekugadzirwa kweakafumurwa skeleton mafuta zvisimbiso, kusanganisira fomula uye chimiro chechiyero cheakafumurwa skeleton mafuta chisimbiso, kusungirirwa kwerabha uye skeleton, antirust. kurapwa kweskeleton yakafumurwa, chitubu uye mold dhizaini uye Kugadziridza, chigadzirwa kukuya tekinoroji, nezvimwe zvakadzidzwa zvakarongeka, asi nekuda kwezvikonzero zvakasiyana, nyika yangu haisati yawana kugadzirwa kwakakura kweakafumurwa skeleton mafuta zvisimbiso.
