Nres CamShafts ua lub luag haujlwm tseem ceeb hauv cov tshuab braking ntawm cov tsheb, tshwj xeeb tshaj yog nyob rau hauv cov uas muaj nruas brakes. Lawv txoj haujlwm kom zoo yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb hauv tsheb thiab txuag kev ua haujlwm. Nov yog cov kev xav tau rau camshafts.
1. Kev siv kho tshuab zog thiab lub zog ruaj khov
Nres CamShafts yuav tsum muaj siab muaj zog. Thaum lub sij hawm braking, lawv thev dhau qhov tseem ceeb torsional thiab cov rog dabtsi yog li nws. Thaum tus brake tau thov, camshaft rotates kom thawb cov khau nres tawm tsam lub nruas nres, tsim lub tsheb ua kom qeeb lossis nres lub tsheb. Cov ntaub ntawv zoo - cov ntaub ntawv muaj zog, xws li cov hlau nplaum alloy, feem ntau siv los tsim cov camshafts. Cov ntaub ntawv no tuaj yeem tiv thaiv kev ntxhov siab rov qab yam tsis muaj kev qaug zog tsis ua haujlwm, uas tuaj yeem ua rau nres sai. Lubricability tseem tseem ceeb heev li camshafts yuav tsum tau ua haujlwm ntev nyob rau hauv ntau qhov kev ua haujlwm kub thaum ib puag ncig lub caij nres tsheb.
2. Sab Nraum Raug
Kho kom meej qhov tseeb qhov tseeb yog qhov tseem ceeb yuav tsum tau ua. Lub cheeb ntawm lub cheeb tsam ntawm camshaft hnub, cov duab thiab qhov loj ntawm lub camtshaft, thiab tag nrho ntev ntawm camshaft yuav tsum tau ua kom tau nruj nruj. Lub cam lobes 'profile ncaj qha cuam tshuam kev txav ntawm cov khau nres. Yog hais tias qhov ntev yog qhov tsis muaj tseeb, cov khau nres yuav tsis raug thawb tusyees, ua rau tsis ncaj ncees braking faib. Qhov no tuaj yeem ua teeb meem zoo li rub mus rau ib sab thaum nres, txo cov qov ua rau muaj kev ua tau zoo, thiab tsis sib luag hnav ntawm cov nres nres. Piv txwv li, ib qho kev sib txawv hauv cam Lawv qhov siab tuaj yeem ua rau cov khau tsis txaus ntseeg, ua rau cov txheej txheem braking tsis txaus ntseeg.
3. Nto tas
Qhov zoo nteg nto tag nrho yog qhov tsim nyog rau kev ua haujlwm du ntawm lub pob txha nres. Cov ntaub ntawv xov xwm tau tig mus rau hauv bearings yuav tsum tau polished heev kom txo kev sib txhuam. Low - Kev sib txhuam tsis yog pab txhawb rau kev hloov pauv ntawm kev quab yuam tab sis kuj pab txo kom txo qis thiab kua muag ntawm lub camshaft thiab cov kabmob. Tsis tas li ntawd, nto ntawm lub cam lobes uas hu rau cov khau sab nres yuav tsum yog tus. Cov nplaim thaiv cov ntoo tuaj yeem ua rau muaj kev hnav khaub ncaws ntau dhau ntawm cov khau nres, ua rau hloov chaw ntxov. Ib lub ntsej muag du kuj tseem ua kom lub zog quab yuam tau kis tau tusyees rau cov khau nres, txhawb nqa cov khaub ncaws tsis sib xws.
4. Cua sov kuj
Thaum lub sij hawm braking, ntau npaum li cas ntawm kev siv nyiaj lub zog tau hloov pauv mus rau hauv tshav kub, uas tuaj yeem ua rau kub ntawm lub vev xaib, suav ntxiv rau lub camshaft, kom nce siab. Nres CamShafts yuav tsum muaj kub txaus kom tswj lawv cov peev txheej ntawm kev kub siab. Kev kub siab - kub - cov txheej txheem kub lossis cov ntaub ntawv nrog cov cua sov - resistant yam khoom feem ntau ua haujlwm. Yog tias camshaft loses nws lub zog lossis seem ruaj khov vim kub, nws tuaj yeem ua rau nres tsis ua haujlwm. Piv txwv li, thaum muaj qhov kub thiab txias, cov khoom siv ntawm camshaft kuj tau mos, ua rau lub cam lobes rau deform thiab cuam tshuam rau kev ua yeeb yam braking.
5. Corrosion Kuj
Nres CamShafts muaj tshwm sim rau ntau yam ib puag ncig, xws li ya raws, txoj kev ntsev, thiab tshuaj lom neeg. Corrosion tuaj yeem ua rau muaj zog tiv thaiv camshaft dhau sijhawm, txo nws lub zog thiab kev ntseeg tau. Txhawm rau tiv thaiv qhov no, corrosion - resistant ntsuas yog coj. Qhov no tuaj yeem suav nrog kev siv corrosion - resistant cov ntaub ntawv, thov kev tiv thaiv kev tiv thaiv zoo li zinc plating lossis pleev xim, lossis siv roj nplua nyeem, lossis siv roj nplua nyeem nrog anti - corrosion thaj chaw. Los ntawm kev ua kom corrosion tsis kam, lub neej ntawm lub pob zeb los nres tuaj yeem txuas ntxiv, thiab kev nyab xeeb ntawm lub kaw lus braking tuaj yeem tswj tau.
Hauv kev xaus, qhov yuav tsum tau rau Camshafts nyob rau hauv cov nqe lus ntawm cov tshuab muaj zog, thiab corrosion qhov, thiab corrosion ua haujlwm yog txhua qhov ua haujlwm zoo thiab kev nyab xeeb ntawm lub tsheb braking. Ntsib cov kev xav tau no yog qhov tseem ceeb rau cov tsheb tuam ntxhab thiab tom qab cov khoom xa khoom kom ntseeg tau tias muaj kev txhim khu kev qha thiab ua tau zoo.
