Chishandiso chemotokari chinogadzirwa nezvinhu zvipi?
Chigadziko chemotokari chinonzi crankshaft bearing (chinozivikanwawo se crankshaft bearing kana kuti large bearing) ibhegi rinotsvedza rine chimiro chakabatana. Chinonyanya kugadzirwa nesimbi kumashure uye alloy layer inoderedza kupera. Chimiro ichi chinobatanidza simba uye kuramba kupera kuti chienderane nenzvimbo yekushanda yeinjini inomhanya zvakanyanya, ine simba rakawanda, uye tembiricha yakakwira.
Muumbirwo wezvinhu zvikuru
Simbi yakadzoserwa shure: Inowanzo gadzirwa nesimbi isina kabhoni yakawanda kana simbi ye alloy, ichipa rutsigiro rwechimiro uye kuomarara.
Chishongo chinoderedza kupfeka: Kana chakabatana zvakananga ne crankshaft, chinoita mabasa ekuderedza kukweshana, mutoro wekutakura, uye kubvisa kupisa. Mhando dzakajairika dzinosanganisira:
Babbitt alloy (yakavakirwa patini kana kuti yakavakirwa pamota)
Hunhu: Kuramba kupfeka zvakanaka uye kugona kuchinjika zvakanaka
Kushandiswa: Inonyanya kushandiswa muinjini dzepeturu dzine mazinga akaderera ekusimbisa
Chiumbwa chemhangura (chakadai sebronze yemutobvu, chiumbwa chemhangura chemutobvu)
Hunhu: Simba guru, kuramba kupfeka zvakanyanya, uye kuramba kupisa kwakanyanya
Kushandiswa: Yakakodzera injini dzedhiziri kana injini dzepeturu dzine mutoro wakawanda
Aluminium-based alloy (yakagadzirwa nearuminiyamu ine sirivha yakakwira kana yakaderera)
Hunhu: Huremu hushoma, kupisa kwakanaka, uye kuramba kupfeka zvakanaka
Mashandisirwo: Parizvino ndiyo inonyanya kushandiswa mumabheyaringi einjini yekupisa mukati. Tsananguro Yakawedzerwa
Ma alloys akagadzirwa nearuminiyamu ave sarudzo huru nekuda kwekushanda kwawo kwakazara, kunyanya akakodzera mainjini emazuva ano ane kumhanya kwakanyanya uye kushanda nguva dzose.
Zvimwe zvigadzirwa zvepamusoro-soro zvicharapwawo zvakaita sekuiswa kwetin plating uye phosphating pamusoro pealloy isingaparare kuti zviwedzere kunaka kwekukweshana.
Ma "crankshaft journals" anowanzo shandiswa ari maviri (kumusoro nepazasi), akaiswa pakati pe "crankshaft main journal" ne "cylinder block", achishandisa firimu remafuta rine 0.005 millimeters kuti riite mafuta emvura uye kudzivirira kusangana kwesimbi zvakananga.
Kuti uone zvinhu zviri mumajenari e crankshaft emotokari imwe, unogona kutarisa bhuku rekugadzirisa kana kubvunza ruzivo rwunoenderana narwo kuburikidza neAutohome Crankshaft Journal.
Mabhuku emotokari e crankshaft ndiwo akakosha pakutakura zvinhu zvinotsvedza muinjini. Mabasa avo makuru anogona kupfupikiswa seizvi:
Tsigira uye gadzirisa crankshaft: Iva nechokwadi chekuti crankshaft inochengetedza nzvimbo yakagadzikana ye radial panguva yekutenderera nekukurumidza, kudzivirira kuzununguka kana kutsauka.
Gadzira firimu remafuta rekuzora mafuta: Gadzira firimu remafuta rakatetepa (rinenge 0.005 millimeters) pakati pe crankshaft journal ne journal, zvichishandura simbi yekukweshana kuita mafuta ekuzora, zvichideredza zvakanyanya kupera.
Deredza kukweshana nekusakara: Kuburikidza nechimiro chemaoko chakagadzirwa nezvinhu zvisingatsvedzereki zvakaita sebabbitt alloy uye copper-lead alloy, zvinobudirira zvinoderedza kukweshana nekukweshana uye kuwedzera hupenyu hweinjini.
Kupisa nekutonhodza: Shandisa mafuta emota kubvisa kupisa kuri kushanda, kudzivirira mabheringi kuti asashande nekuda kwekupisa kwakanyanya.
Nzvimbo yeAxial (yemamwe marudzi): Majenali e flanged crankshaft anogonawo kudzikamisa kufamba kwe axial kwe crankshaft iri pa axis, zvichiita kuti zvikamu zvinofamba zvive panzvimbo chaiyo.
Kana mafuta asina kunaka, kubatanidzwa kwacho kusina kunaka, kana kuti mafuta einjini asina kuchena, zvinogona kukonzera kuti firimu reoiri ribvaruke, zvichikonzera zvikanganiso zvakakura zvakaita sekupisa journal, kubata shaft, nezvimwewo, zvichiratidzwa nekudzikira kwesimba reoiri, ruzha rusina kujairika, uye simba rakaderera. Saka, kuchinja oiri yeinjini nemafirita nguva dzose, uye kuchengetedza mota zvichienderana nezvinodiwa, zvakakosha zvikuru pakudzivirira mabheringi ecrankshaft.
Kukundikana kwebearing ye crankshaft mumotokari (inozivikanwa se "kupedza bearing" kana "kuputsa bearing") ndeimwe yematambudziko makuru emuchina einjini. Kazhinji inokonzerwa nekukundikana kwemafuta, zvichikonzera kukuya kwakaoma, kupisa kwakanyanya, uye kutobata pakati pejenari re crankshaft nebearing. Muzviitiko zvakakomba, zvinogona kutokonzera kuparadzwa kweinjini.
Zviratidzo zvikuru:
Ruzha rusina kujairika: Injini inoburitsa ruzha rusina kunaka rwe "tang, tang" kana "buzzing" rwesimbi, kunyanya kana ichimhanyisa mota.
Alarm yekumanikidza mafuta: Chiratidzo chekumanikidza mafuta chiri padashboard chinopenya, uye chiyero chekumanikidza mafuta chinoratidza kuverenga kwakaderera.
Kurasikirwa kwesimba: Simba reinjini rinobuda rinoderera, uye kumhanya kunova kusina simba.
Utsi hwakanyanya: Utsi hutema hunogona kuburitswa.
Alarm yekupisa kwakanyanya: Tembiricha yemvura yakakwira zvisina kujairika kana tembiricha yemafuta.
Kutadza kutanga kana kuti injini ikamira: Muzviitiko zvakanyanya, crankshaft nebearing zvinopiswa uye zvinonamirwa pamwe chete, zvichidzivirira injini kuti isatenderere.
Zvikonzero zvakajairika:
Matambudziko ekuisa mafuta mumafuta:
Kusakwana kwesimba remafuta (kushaikwa kwepombi yemafuta, kutadza kushanda zvakanaka kwevharuvhu, kudonha kweseti yemafuta).
Kusakwana kana kuti kuora kwehuwandu hwemafuta (kusagadziriswa kwenguva refu, kushandiswa kwemafuta asina kunaka).
Kusanganiswa kwemafuta (chinhu chinotonhodza chiri kupinda mupoto yemafuta, zvakaita sekukundikana kweringi inovhara mvura yemuchina wecylinder).
Nzira dzemafuta dzakavharika (tsvina, makabhoni akachengetwa, simbi dzakachekwa dzinovhara nzira huru yemafuta kana maburi emafuta e crankshaft).
Matambudziko ekugadzira nekubvumidza:
Kusakwana kana kuti kusakwana kwekubvisa mabheyaringi (zvichikanganisa kuumbwa kwefirimu remafuta).
Kusarudzwa kana kuiswa kwemabheyaringi zvisiri izvo.
Maitiro ekushandisa uye mashandiro:
Kutanga injini nekumhanya kwakanyanya uye pasi pemutoro unorema mushure mekuitanga kutonhora.
Kutyaira mota zvakanyanya kwenguva refu uye kumhanya zvakanyanya.
Kudzima injini pakarepo kana yapisa, zvichiita kuti firimu remafuta rikuvare.
Zvikanganiso zvekugadzira kana kugadzira:
Kupera kwepasi kusina kunaka uye mhando yezvinhu zve crankshaft kana bearing.
Kutenderera kwejenari re crankshaft kusina kutsanangurwa, kushanduka, nezvimwewo.
Mazano ekurapa:
Misa mota nekukasika: Kana zviratidzo zvekusashanda zvakanaka kwebheya (zvakadai seruzha rusina kujairika, alarm yekumanikidza mafuta) zvikaonekwa, misa mota nekukasika uye usarambe uchityaira. Izvi zvinoitirwa kudzivirira kukuvara kwakawanda.
Kugadzirisa kwehunyanzvi:
Tsiva crankshaft main bearing (large bearing) uye connecting rod bearing (small bearing).
Tarisa kana crankshaft journal yakakwenywa, yakasanganiswa, yakadhonzwa, kana kuti yakakanganisika; kana kukuvara kwakanyanya, zvakakosha "kukuya shaft" kana kutsiva crankshaft.
Chenesa nzira yemafuta, dzorera pombi yemafuta nefirita, uye gadzirisa nzvimbo dzinobuda mvura mugadziriro yekutonhodza.
Ongorora kana ichigona kushandiswa zvakare:
Kana iri "kukundikana kwemabheyaringi madiki", mushure mekugadzwa kwehunyanzvi nekutsiviwa kwebheyaringi idzva, inogona kushandiswa zvakare.
Kana crankshaft journal yakasakara zvakanyanya, crankshaft yakakanganisika kana kuti yakatyoka, saka zvinodikanwa kutsiva crankshaft. Hazvikurudzirwi kuramba uchishandisa chikamu chekare.
Matanho ekudzivirira:
Gara uchitarisa uye chinja mafuta nefirita zvinoenderana nezvinodiwa.
Usati watyaira, simbisa kuti huwandu hwemafuta huri mukati mehuwandu hwakajairika (chiyero chepakati chedipstick).
Dzivisa kushanda nekukurumidza kana mutoro unorema pakarepo mushure mekutanga kutonhora.
Pisa injini kusvika patembiricha yemvura inopfuura 40°C usati watanga muchando.
Nyatsocherechedza mamiriro emafuta: Kana paine emulsification (ruvara ruchena, furo rakawanda), kusviba kwakaderera, kana kunhuwa kwepeturu, gadzirisa nekukurumidza.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
