Crankshaft bending deformation: Iyo radial runout kukanganisa kazhinji haifanirwe kudarika 0.04 ~ 0.06mm. Crankshaft jenari: Iko kutenderera uye cylindricity kukanganisa kazhinji haipfuure 0.01 ~ 0.0125mm.

(1) Sarudza micrometer yekunze ine renji yakakodzera zvinoenderana nejenari re crankshaft

(2) Yera huwandu hwekupfeka pa crankshaft main jenari uye yekubatanidza rod jenari ine yekunze micrometer zvinoenderana nemutemo wekupfeka, uye kuverenga kutenderera uye cylindricity kukanganisa. Tanga kuyera kumativi ose ejenari gomba remafuta, uye wozosarudza 90 ° kuyera zvakare. Zvikamu zviviri zvinosarudzwa pajenari rega rega, uye chikamu chega chega chinosarudzwa chingangoita 1/3 yehurefu hwejenari.

(3) Kutsemuka kwakachinjika hakubvumidzwe pamusoro pejenari re crankshaft. Pakutsemuka kwakachinjika, kana kudzika kuri mukati mejenari rekugadzirisa saizi, inogona kugadzika kure nekukuya, zvikasadaro inofanira kuraswa.

(4) Kana kutenderera uye cylindricity kukanganisa kweinjini crankshaft yakakura kupfuura 0.025mm, inofanirwa pasi uye kugadziriswa zvinoenderana nehukuru hwekugadzirisa. 3. The crankshaft journal repair yeSantana neJetta mota injini yakakamurwa kuita nhanho nhatu dzehukuru hwekugadzirisa, ine nhanho imwe pa 0.25mm.

(5) Izvo zvinhu zve crankshaft zvakasiyana, uye zvinodiwa zvekushanda zvakasiyana panguva yekutonhora kwekugadzirisa. Chenjerera kudzivirira crankshaft kubva pakutyoka kana kutsemuka kutsva.

(6) Ngwarira kusiyanisa hukama pakati peiyo radial denderedzwa runout kukanganisa kwejenari, iko kukanganisa kwekutwasuka kweiyo crankshaft axis, uye curvature.

(7) Pakuyera saizi yejenari re crankshaft, kutenderera uye zvikanganiso zvecylindricity, inofanirwa kudzikamiswa negomba remafuta.
