Crankshaft dabtsi yog khoov deformation: Qhov yuam kev radial runout feem ntau yuav tsum tsis pub tshaj 0.04 ~ 0.06mm. Crankshaft phau ntawv journal: Lub roundness thiab cylindricity yuam kev feem ntau tsis tshaj 0.01 ~ 0.0125mm.

(1) Xaiv lub micrometer sab nraud nrog qhov tsim nyog raws li cov ntawv xov xwm crankshaft

(2) Ntsuas qhov hnav ntawm lub crankshaft lub ntsiab phau ntawv xov xwm thiab txuas cov ntawv xov xwm nrog ib lub micrometer sab nraud raws li txoj cai hnav, thiab xam qhov kev sib tw thiab cylindricity yuam kev. Thawj qhov ntsuas ntawm ob sab ntawm cov ntawv xov xwm roj qhov, thiab tom qab ntawd xaiv 90 ° los ntsuas dua. Ob ntu raug xaiv rau txhua phau ntawv, thiab txhua ntu raug xaiv kwv yees li ntawm 1/3 ntawm qhov ntev ntawm phau ntawv.

(3) Cov kab nrib pleb tsis raug tso cai rau saum npoo ntawm cov ntawv xov xwm crankshaft. Rau cov kab nrib pleb, yog tias qhov tob yog nyob rau hauv phau ntawv kho qhov loj, nws tuaj yeem ua rau hauv av los ntawm kev sib tsoo, txwv tsis pub nws yuav tsum tau muab pov tseg.

(4) Thaum lub roundness thiab cylindricity yuam kev ntawm lub cav crankshaft yog ntau tshaj 0.025mm, nws yuav tsum tau muab tso rau hauv av thiab kho raws li kho qhov loj. 3. Lub crankshaft journal kho ntawm Santana thiab Jetta lub tsheb cav tau muab faib ua peb theem ntawm kev kho qhov loj, nrog ib theem ntawm 0.25mm.

(5) Cov khoom siv ntawm lub crankshaft yog qhov sib txawv, thiab cov kev ua haujlwm yuav tsum sib txawv thaum lub caij txias txias kho. Ua tib zoo tiv thaiv lub crankshaft los ntawm kev tawg lossis tawg tshiab.

(6) Ua tib zoo saib kom paub qhov txawv ntawm kev sib raug zoo ntawm lub voj voog radial runout yuam kev ntawm phau ntawv journal, qhov tsis ncaj ntawm lub crankshaft axis, thiab curvature.

(7) Thaum ntsuas lub crankshaft phau ntawv loj, roundness thiab cylindricity yuam kev, nws yuav tsum tau staggered nrog lub qhov roj.
