(1) Tarisa uye gadzirisa iyo axial clearance
Paunenge uchitarisa iyo axial clearance yeinjini inoshandisa thrust flange yekumisikidza axial, isa inonzwika gauge pakati pepamberi pekupedzisira kwejenari rekutanga recamshaft uye yekukanda flange kana pakati pekupedzisira kumeso kweiyo nguva yegiya hub uye yekukanda flange. Ukobvu hweiyo feeler gauge ndiyo axial clearance yecamshaft. Iyo inowanzoita 0.10mm, ine muganho mukuru we0.25mm. Kana iyo clearance isingaenderane nezvinodiwa, inogona kugadziriswa nekuwedzera kana kuderera ukobvu hwekukanda flange.

(2)Kuongorora uye kugadziriswa kwecamshaft bending deformation
Iko kubhenda deformation yecamshaft inoyerwa neradial runout kukanganisa kwecamshaft yepakati jenari kumajenari kumagumo ese. Nzira yekuongorora inoratidzwa mumufananidzo. Isa camshaft pane V-yakaita simbi, uye V-yakaita simbi uye dial chiratidzo paflat plate, kuitira kuti dial chiratidzo chekubata chiri pakatarisana neiyo camshaft yepakati magazini. Shandura camshaft uye utarise mutsauko weiyo dial chiratidzo chetsono, inova dhigirii rekukotama recamshaft. Mushure mekunge kuongorora kwapera, enzanisa mibairo yekuongorora nehuwandu hunokosha kuti uone kana kugadzirisa kana kutsiva.

(3) Zvimwe zvinhu zvekugadzirisa camshaft
1) Kutariswa kweiyo nguva yegiya shaft jenari kiyi: Iyo symmetric ndege yenguva yegiya shaft jenari kiyi inofanirwa kuenderana nendege inofananidzwa yekusimudza kwakakwira kwekutanga silinda yekutora uye kupera kwemakamera. Kupfeka kwayo kuchachinja nguva yevhavha. Kana kiyi nzira yakapfekwa, inogona kuvhurwazve nepamusoro welding kana kuvhurwa panzvimbo nyowani.
2) Kunyanya kupfeka kwepeturu pombi dhiraivha eccentric vhiri: Kupfeka kwakanyanya kwepeturu pombi drive eccentric vhiri inowanzo 1mm. Kana ikapfuura muganhu uyu, camshaft inofanira kutsiviwa.

Diameter runout value: chiyero - 0.01 ~ 0.03 mm, muganhu - 0.05 ~ 0.10 mm.
3) Kuongorora uye kugadziriswa kwekam kupfeka
Kana iyo yakanyanya kusimudza kudzikisa kukosha kwekamera yakakura kupfuura 0.40mm kana iyo yakawedzera kupfeka yekamera yepamusoro inodarika 0.80mm, iyo camshaft inofanira kutsiviwa; kana iyo yakawedzera kupfeka yekam pamusoro iri pasi pe0.80mm, iyo cam inogona kukuyiwa pane camshaft grinder.
Nekudaro, iwo makamera emazuva ano enjini yemotokari camshafts ese akasanganiswa mutsara mhando. Nekuda kweiyo yakanyanya kukwirira kugadzirisa uye mutengo wakakura wekugadzirisa, iwo haawanzo gadziriswa parizvino, uye camshaft inowanzotsiviwa.

4) Kuongorora uye kuchengetedzwa kwecamshaft magazini uye mabearings
① Kuongororwa kwejenari yecamshaft uye kubereka: Shandisa micrometer kuyera kukanganisa kwekutenderera uye cylindricity kukanganisa kwejenari yecamshaft. Iko kukanganisa kwekutenderera kwejenari yecamshaft haifanire kunge yakakura kupfuura 0.015mm, uye kukanganisa kwecoaxiality yejenari yega yega haifanire kudarika 0.05mm. Kana zvisina kudaro, inofanira kugadziriswa maererano nemutongi.
② Kuongororwa kweiyo camshaft inotakura: Kana iyo inofananidzwa yemvumo ye camshaft inotakura inodarika muganho wekushandisa, fanicha nyowani inofanira kutsiviwa.
