Yuav ua li cas siv tus micrometer mus sim cov crankshaft runout?
Jul 11, 2025|
Kev kuajtus kws cog qoob looKev khiav tawm yog ib kauj ruam tseem ceeb hauv kev txiav txim siab yog tias crankshaft yog khoov lossis deformed, tshwj xeeb tshaj yog thaum kev txhim kho lub cav lossis hloov cov crankshaft.
Hauv qab no yog cov kauj ruam dav dav rau kev sim ntsuas cov crankshaft rollout.
✅1.Sus cov kev txhawb nqa Saimermetrical:
Lub crankshaft feem ntau yog muab tso rau ntawm ob v - blocks, cov cim kev txhawb nqa ntawm lub ntsiab lus tseem ceeb ntawm ob qho kawg los xyuas kom muaj kev sib hloov dawb.
✅2.install lub Dial qhia:
Siv cov khoom sib nqus lossis cov qauv ntsuas kom haum rau cov kev soj ntsuam micrometer venne rau kev ntsuas ntsuas:
Radial Khiav: Cov kev sojntsuam tau muab tso rau ntawm ib sab ntawm cov ntawv sau phau ntawv nrab, tig lub crankshaft ib lub voj voog, thiab sau qhov siab tshaj plaws thiab yam tsawg kawg nkaus nyeem sib txawv.
Kev khiav tawm axial: cov kev sojntsuam tau muab tso rau thaum kawg ntawm lub tshuab flange, thiab qhov kawg lub ntsej muag runge yog ntsuas los ntawm kev sib hloov.
✅3.Nyig tus nqi ntaus:
Khiav tawm=tus nqi siab tshaj plaws - tus nqi tsawg kawg nkaus, feem ntau ntsuas hauv chav nyob 0.001mm
Cov Qauv Txheej Txheem (nrog rau kev siv cov diesel / roj av tshuab)
✅radial runout (crankshaft dabtsi yog): Nruab nrab phau ntawv sau nyeem ntawv, tag nrho qhov sib txawv / 2 yog khoov. Cov kev txwv siab tshaj plaws feem ntau tsawg dua li lossis sib npaug rau 0.03mm, thiab tus qauv uas muaj tsawg dua lossis sib npaug rau 0.05mm
✅end ntsej muag axial runout: feem ntau tswj tau nyob rau hauv ntau tsawg dua los yog sib npaug rau 0.0.2mm
✅Cleaning thiab pre {{- tighting: Txhua qhov chaw sib tiv tauj yog ntxuav, thiab kev sojntsuam} phoo ntawv ~ 1mm kom tsis txhob ntsuas yuam kev.
✅slow thiab txawm tias kev sib hloov: manually tig lub crankshaft ib lub voj voog, saib cov kev hloov pauv, thiab zam inertia.
Cov kev txhawb nqa ✅symetrical: Ob xaus yog nyob rau tib theem kom ntseeg tau tias yog qhov ntsuas tau raug.
{{- Nto Taw Qhia: Nws raug pom zoo kom muab cov ntawv sau sib txawv ntawm cov ntawv sau sib txawv los ntsuas kev sib kis
