Fault Diagnosis thiab Tshem Tawm Cav Crankshaft Fracture
Mar 11, 2023| Txhawm rau tiv thaiv lub crankshaft los ntawm kev tawg, cov kev ntsuas hauv qab no tuaj yeem ua thaum kho:
Ua ntej ntawm tag nrho cov, ua ntej kho lub crankshaft, nws yog tsim nyog los ua tib zoo xyuas seb puas muaj cov kab nrib pleb nyob rau hauv lub crankshaft, them tshwj xeeb mloog mus rau lub fillet hloov chaw. Yog tias muaj cov kab nrib pleb, cov ncej yuav tsum tau muab pov tseg. Thaum polishing cov phau ntawv journal, nws yog ib qho tsim nyog yuav tsum tuav ib lub vojvoog ntawm lub fillet ntawm phau ntawv sau thiab crank caj npab. Nws tsis raug tso cai rau arbitrarily txo qhov loj ntawm lub vojvoog ntawm lub fillet. Kev saib xyuas yuav tsum tau them rau qhov ua tiav ntawm lub fillet, txwv tsis pub kev ntxhov siab yuav tshwm sim thiab lub crankshaft yuav tawg.
Qhov thib ob, thaum qhov ntev ntawm cov ntawv xov xwm tshaj li qhov txwv, nws yog ib qho tsim nyog los xaiv txoj kev uas muaj kev cuam tshuam me me rau lub zog qaug zog ntawm phau ntawv xov xwm kom rov zoo. Piv txwv li, siv cov tshuaj tsuag plating los txo qhov qaug zog ntawm cov phau ntawv journal yog tsawg, thaum siv surfacing kom rov qab lub zog qaug zog yog txo qis.
Tom qab ntawd, qhov haum clearance thiab xaus clearance ntawm txhua phau ntawv journal thiab bearing yuav tsum ua raws li cov qauv. Kev tshem tawm ntau dhau tuaj yeem ua rau lub crankshaft tau yooj yim puas vim muaj kev cuam tshuam, thaum qhov kev tshem tawm me me tuaj yeem tawg lub crankshaft vim tuav lub ncej. Hauv kev sib dhos, lub sijhawm sib tsoo yuav tsum raug ntsuas kom raug, tsis dhau ntxov lossis lig dhau lawm, thiab yuav tsum tau them nyiaj rau qhov sib npaug ntawm lub crankshaft, flywheel, thiab clutch.
