Crankshaft beng deformation: Phoso ea radial runout hangata ha ea lokela ho feta 0.04 ~ 0.06mm. Koranta ea Crankshaft: Phoso ea ho pota-pota le cylindricity ka kakaretso ha e fete 0.01 ~ 0.0125mm.

(1) Khetha micrometer e kantle e nang le mofuta o loketseng ho latela koranta ea crankshaft

(2) Lekanya boholo ba moaparo ho jenale ea sehlooho ea crankshaft le koranta ea rod e hokelang ka micrometer e kantle ho latela molao oa ho apara, 'me u bale liphoso tsa ho pota-pota le cylindricity. Lekanya pele mahlakoreng ka bobeli a lesoba la oli la koranta, ebe u khetha 90 ° ho lekanya hape. Ho khethiloe likarolo tse peli bakeng sa koranta ka 'ngoe, 'me karolo ka' ngoe e khethiloe hoo e ka bang 1/3 ea bolelele ba koranta.

(3) Mapetso a hlabang ha a lumelloe holim'a bukana ea crankshaft. Bakeng sa mapetsong a pota-potileng, haeba botebo bo le ka har'a boholo ba tokiso ea koranta, e ka siloa ka ho sila, ho seng joalo e lokela ho tlosoa.

(4) Ha phoso e chitja le cylindricity ea crankshaft ea enjene e kholo ho feta 0.025mm, e lokela ho siloa le ho lokisoa ho latela boholo ba tokiso. 3. Tokiso ea koranta ea crankshaft ea lienjine tsa likoloi tsa Santana le Jetta e arotsoe ka mekhahlelo e meraro ea boholo ba tokiso, ka boemo bo le bong ho 0.25mm.

(5) Thepa ea crankshaft e fapane, 'me litlhoko tsa ts'ebetso li fapane nakong ea khalemelo ea khatiso e batang. Hlokomela ho thibela crankshaft ho robeha kapa mapetsong a macha.

(6) Ela hloko ho khetholla kamano pakeng tsa phoso ea radial circle runout ea koranta, phoso ea ho otloloha ea axis ea crankshaft, le curvature.

(7) Ha o metha boholo ba jenale ea crankshaft, ho pota-pota le liphoso tsa cylindricity, e lokela ho thekesela ka lesoba la oli.
