Basa re crankshaft ndere kushandura gasi rekumanikidza kubva mupiston yekubatanidza tsvimbo boka kuita torque yekubuda kwekunze, uye kutyaira chitima chevhavha uye zvimwe zvekubatsira. Mazhinji acho akagadzirwa nemhando yepamusoro yepakati kabhoni simbi, yepakati alloy kabhoni simbi kana spheroidal graphite cast iron. Chimiro che crankshaft chinosanganisira kumberi shaft, mainjenari, yekubatanidza tsvimbo, crank, counterweight, rear shaft, nezvimwewo, uye kune mafungu emafuta anomhanya nemujenari guru, crank uye yekubatanidza rod redhiyo yekuzora iyo huru jenari uye yekubatanidza tsvimbo. . Journal. Nekuti ichaiswa pasi pesimba rakasiyana-siyana mukushandiswa, pachave nehumwe huwandu hwekupfeka, uye zvikamu zvakasiyana zvine maitiro akasiyana ekupfeka.
Pfeka hunhu hwejenari huru uye main bearing bush
Kupfeka kwejenari huru pamwe negwara reaxial kunofanirwa kuve kwakafanana, uye huwandu hwekupfeka munzira yeradial hauna kuenzana, uye pachave neine ellipticity. Sezvo bhuku repakati rinowanzoiswa pasi pesimba rakakura, huwandu hwayo hwekupfeka hunowanzo hukuru kupfuura hwemigumo miviri. Iyo radial kupfeka kwegwenzi rinotakura rinoenderana neiyo yejenari huru. Chikamu chikuru chekupfeka chiri paberero rezasi, uye kupfeka kwegwenzi repakati rinotakura rakakura kupfuura iro remigumo miviri.
Pfeka maitiro ekubatanidza tsvimbo yejenari uye yekubatanidza tsvimbo gwenzi
Kupfeka kwe radial yejoining rod magazines uye mabearings hazvina kuenzana, uye kupfeka kwemukati kunenge kwakakura. Kupfeka kusina kuenzana kunoita kuti jenari yerodhi yekubatanidza igadzire imwe ellipse munzira yeradial, uye iyo axial dhizaini inowanzo yunifomu. Iyo yekubatanidza tsvimbo ine asymmetric yakakura-yekupedzisira chimiro ichave taped mushure mekupfeka nekuda kwekusaenzana kwemutoro kugovera pane yekubatanidza tsvimbo jenari; iyo tsvimbo yekubatanidza ine symmetrical yakakura-yekupedzisira chimiro ichakonzera mhedzisiro imwechete kana yakakotama.
Chikamu chinonyanya kupfekwa chejenari yerod yekubatanidza kazhinji iri padivi remukati rejenari rega rega, ndiko kuti, padivi pe crankshaft centerline, kuitira kuti jenari ibude kunze; uye chikamu chinopfekwa mukoni chinowanzova padivi pemukoto wemafuta ekuzora panosungirirwa tsvina. Padivi uye nzvimbo iyo simba rakakura.
Kupfeka kwe crankshaft kunogona kuyerwa ne micrometer. Kupfeka kwejenari pfupi ye crankshaft kunonyanya kuongororwa zvikanganiso zvekutenderera, uye kune majenari marefu, kutenderera uye cylindricity kukanganisa kunofanirwa kuongororwa. Iyo chaiyo yekuyera nzira ndeye: tora zvikamu zviviri zvejenari rega rega, uye tora mapoinzi maviri pachikamu chimwe nechimwe. Iyo hafu yemusiyano pakati pehupamhi hwepakati uye dhayamita diki yechikamu chimwe chete chikanganiso chekutenderera; hafu yemusiyano pakati pehupamhi hwepamusoro uye dhayamita diki muzvikamu zviviri ndeye cylindricity kukanganisa. Pasi pemamiriro ekushanda akajairwa, kupfeka kwe crankshaft kudiki zvakanyanya, kazhinji haapfuure 0.01mm, uye cylindricity yakatoderera kupfuura 0.0025mm.
Mamiriro akajairika ekukuvadzwa kwecrankshaft anosanganisira kupfeka kwejenari, kutsemuka, kutsva, kubhenda kana kuputsika, nezvimwewo. Tinogona kuongorora mamiriro ekushanda kweinjini uye chikonzero chekukuvadza kubva pakupfeka kwe crankshaft. Semuenzaniso, huwandu hwekupfeka kwe crankshaft hwakanyanya, uye gwenzi rinotakura rinotoburitsa ruvara rwekumashure. Mamiriro ezvinhu aya anowanzo kukonzerwa nekusazora mafuta, kuderera kweoiri, uye oiri isingaite zvinodiwa pakushandisa. Iyo silinda ye crankshaft yakakura kwazvo, zvichiratidza kuti injini yanga ichishanda pasi pemutoro unorema kwenguva yakareba. ; Iyo crankshaft inopisa, blues, kukiya, inofanirwa kukonzerwa nekusagadzikana kwemafuta, iyo inonyanya kuzivikanwa ndeyekushaya mafuta.
