Iyo crankshaft, ingave iri yemotokari injini crankshaft, yemugungwa injini crankshaft kana yeindasitiri pombi crankshaft, inobata chiitiko chakasanganiswa chekuchinjanisa kukotama uye kuchinjisa mitoro yekutenderera panguva yekutenderera. Zvikamu zvine njodzi zve crankshaft, kunyanya shanduko yefillet pakati pejenari uye crank Dzimwe nguva, crankshaft inotyoka nekuda kwekuwanda kwekushushikana.

Naizvozvo, mamiriro ebasa anoda kuti crankshaft ive nesimba rakakwana kuti ive nechokwadi chekuti crankshaft haityoke panguva yekushanda. Parizvino, kushandiswa kwepfuti peening kushandura kuneta kuramba kwe crankshafts kwakashandiswa zvakanyanya mumhando dzakasiyana dzekushandisa, uye mhedzisiro yacho inogutsa.

Kuenzaniswa nekuremara kwechinyakare kukunguruka maitiro, nekuda kwekudzikiswa kweiyo crankshaft yekugadzirisa tekinoroji, makona akatenderedzwa ejenari yega yega anonetsa kuenzanisa neroller, izvo zvinowanzokonzera kugeda-geda kwemakona akatenderedzwa, uye crankshaft mushure mekukunguruka. akaremara zvakanyanya, kwete zvinobudirira. Iyo nzira yekupinza peening ndeye kushandisa pellets ine dhayamita yakadzorwa uye rimwe simba kugadzira rukova rwepellets pasi pekuita kwekumhanya-mhanya kwemhepo uye kuenderera mberi nekuapfapfaidza pamusoro pesimbi pamusoro pe crankshaft, sekurova nesando zvisingaverengeki zvidiki. sando dzekugadzira pamusoro pe crankshaft Gadzira yakasimba zvakanyanya deformation yepurasitiki uye gadzira basa rinotonhora rakaomeswa layer. Kuzvitaura zviri nyore, nekuti crankshaft inoiswa pasi peakasiyana emagetsi ekucheka masimba panguva yekugadziriswa, kuparadzirwa kwekushushikana pamusoro payo, kunyanya kuchinjika-chikamu chekuchinja kwe crankshaft, haina kuenzana zvakanyanya, uye inoiswa kune alternating stress panguva yebasa, saka. zviri nyore Stress corrosion inoitika uye hupenyu hwekuneta hwe crankshaft hunodzikiswa. Iyo yepfuti yekupenengura maitiro ndeye kuunza pre-compression kushushikana kudzikamisa kushushikana kusimba uko chikamu chichagamuchira mune ramangwana rekushanda kutenderera, nekudaro kuvandudza kuramba kuneta uye yakachengeteka sevhisi hupenyu hweworkpiece.

Mukuwedzera, crankshaft forging blanks inogadzirwa zvakananga kubva kune simbi ingots kana kuumbwa kubva kune inopisa-yakakungurutswa simbi. Kana maitiro ekugadzira nekukungurutsa asina kudzorwa nemazvo, panowanzove nekuparadzaniswa kwechikamu, mhodzi dzakakasharara dzechimiro chepakutanga, uye kusanzwisisika kwemukati kugovera kwemukati mune blanks. Uye zvimwe zvikanganiso zvemetallurgical uye sangano, nokudaro kuderedza kuneta kwehupenyu hwe crankshaft, nzira yekusimbisa inogona kugadzirisa chimiro uye kuvandudza zvakanyanya kuneta kwayo.
