Lub khib nyiab heev nyob rau tam sim no industrial, yuav kom muaj kev cuam tshuam, nws yog qhov tsim nyog yuav tau xav txog cov khoom ntawm cov ntaub ntawv.Generally, vim yog qhov zoo dua mechanical zog ntawm carbon cov ntaub ntawv, nws yog dav siv nyob rau hauv cov tswv yim ua hauj lwm, tshwj xeeb tshaj yog 45 daim ntaub ntawv steel.
Yog hais tias peb xav kom ntxiv txhim kho cov khoom siv zog ntawm cov shafts, peb siv tau zoo los sis ua tau zoo.Yog hais tias lub zog yog me me, ces cov pa carbon hlau ntawm Q235 thiab Q275 siv tau.Thiab vim tias qee qhov tshwj xeeb ntawm kev ua haujlwm , lawv tuaj yeem xaiv hlau hlau. Cov khoom no muaj zoo mechanical zog, tab sis nws yog kim dua.Piv txwv hais tias, qib high-speed ncej ntawm sliding bearing yog feem ntau ua los ntawm cov qis carbon alloy cov hlau steel xws li 20Cr thiab 20CrMnTi.Thiab nws kuj xav tau carburizing thiab quenching rau txhim kho txoj kev ua haujlwm hnyav.
Ntxiv rau qhov, thaum xaiv cov ntaub ntawv, peb yuav tsum xav txog cov hauj lwm tshwj xeeb.Piv txwv li, qee zaum, cov ncej ua haujlwm kub siab, kev kub ceev lossis hnyav kub, ces nws yog qhov yuav tsum tau xyuas kom nws muaj qhov kub thiab txias cov khoom, yog li nws yog feem ntau siv los xaiv 40CrNi, 38CrMoAlA thiab lwm cov hlau hlau alloy.
Muaj cov xwm txheej tshwj xeeb uas peb xav tau los siv cov ncej loj lossis ntau dua, ces yuav tsum tau xaiv cov hlau cam los yog cov khoom siv hlau luam. Ib yam li siv hlau luam hlau ua crankshaft, camshaft, lwm yam zoo li, tsis tas yuav txuag tau tus nqi, tab sis kuj muaj kev haum siab haum.
Thaum xaiv cov ntaub ntawv, peb yuav tsum tau ua haujlwm ua haujlwm thiab siv qhov yuav tsum tau xaiv. Thaum lub sijhawm xaiv tsis tsim nyog, ces tej zaum koj yuav tsis ua haujlwm ntawm lub qhov muag, xws li qaug zog ntawm pob, tawg pob zeb, hloov deformation, thiab lwm yam.
