Iyo crankshaft ndiyo chikamu chikuru chinotenderera cheinjini uye chikamu chakakosha cheinjini. Zvinoenderana nesimba uye mutoro wainotakura, crankshaft inoda kuve nesimba rakakwana uye kusimba, uye pamusoro pejenari inoda kusapfeka, kushanda zvakafanana, uye kuve nechiyero chakanaka.

Nitriding kurapwa

Nekuda kwekukosha kwe crankshaft, kurapwa kwekupisa kwe crankshaft kune zvakanyanya kuomarara zvinodiwa zve deformation. Kune akawanda-akagadzirwa crankshafts, ion nitriding kupisa kurapwa inowanzo shandiswa kuvandudza chigadzirwa mhando. Kune kabhoni simbi kana simbi yakakandwa kana yakaderera alloy simbi, vanhu vanowanzo shandisa ion yakapfava nitriding (yakaderera tembiricha kabhoni, nitrocarburizing) tekinoroji. Nhamba huru yemaitiro yakaratidza kuti kuoma uye kupinda kweiyo nitrided layer kune hukama hwakanyanya nekupisa, nguva uye kuisa pfungwa. Iyo tembiricha yekudzora huwandu hweion yakapfava nitriding inofanirwa kunge iri pamusoro pe540 ℃ uye pazasi tembiricha yekuchembera, uye mwero wakakodzera wekudziya unofanirwa kusarudzwa zvinoenderana nezvinodiwa zvezvikamu.

Iyo ion nitriding kupisa kurapwa ine diki deformation, iyo inogona kunyatso simbisa iyo deformation. Iro jena uye rakajeka rakatsetseka uye rakaputika rakafanana, hupamhi hwepamusoro-soro hunodzoreka, kutenderera kwekurapa kupfupi, uye kushanda kwakakwirira. Parizvino, iyo ion nitriding vira inogadzirwa nekambani yedu yakawana kugadzirwa kwakawanda kwe crankshafts, uye mhando ye nitriding yakakwira, iyo inogamuchirwa nevatengi.
