Mechanical gearbox nyob ntawm cov iav, uas yog qhov tseem ceeb; cov ntaub ntawv siv rau lawv ncaj qha cuam tshuam cov iav kev ua tau zoo thiab kev pabcuam lub neej. Dab tsi yog cov khoom siv feem ntau ua haujlwm rauiav manufacturing? Yuav ua li cas ib tug yuav tsum xaiv cov khoom tsim nyog kom haum rau ntau qhov chaw ua haujlwm? Cia peb mam li tshuaj xyuas kom zoo.
Cov ntaub ntawv twg haum rau ntau yam iav tsim?
1. Cov khoom siv tsis yog xim hlau
Kev ceev ceev, lub teeb-thauj khoom, qis-precision iav kis tau feem ntau hu rau cov nylon thiab txoj phuam kom zoo nkauj. Tsim nyog rau cov kev ua haujlwm tsawg-kev ua haujlwm, lawv tuaj yeem muaj suab nrov qis.
2. Ua los ntawm Forging Steel
Kev kho cua sov lossis tshuaj kho cua sov pab pab txhim kho cov neeg kho tshuab zoo thiab hniav tawv ntawm cov hlau forged; Nws kuj tseem nce nws cov kev nruj zoo thiab cuam tshuam tsis kam. haum rau gears paub ntau dua thauj thiab cuam tshuam.
3. Cam khwb cia hlau
Cov iav loj dua haum cam khwb cia hlau vim nws muaj zog thiab hnav tsis kam. Cam khwb cia hlau tuaj yeem muab kev ua haujlwm ruaj khov nyob rau hauv cov khoom loj tom qab annealing thiab normalising.
4. Alloy Steel
Raws li tsim nyog, txoj kev sib xyaw ntawm alloy steel yuav pab tau nws cov kev tsis txaus siab, cuam tshuam kuj, hnav tsis kam, tiv thaiv kev sib raug zoo. Kev kho cua sov yuav txhim khu kev siv cov neeg kho tshuab zoo; Yog li, nws yog qhov tsim nyog rau high-zoo, zoo heev zog, tshwj xeeb yog cov siv hauv kev siv aviation.
5. Tsawg Cov Hlau Hlau
Cov pa roj carbon tsawg tsawg muaj qhov ua tau zoo heev thiab tsim nyog rau kev tiv thaiv lub zog los ntawm kev tawg nyob rau hauv kev cuam tshuam loj rau kev siv cuam tshuam nrog kev cuam tshuam loj.
6. Cov pa roj carbon steel nruab nrab
Kev kub ceev kaw kaw cov thawv iav hu rau cov pa roj carbon steel, uas tseem tau khav theeb hniav muaj zog thiab yog qhov tsim nyog rau cov khoom lag luam kom muaj txiaj ntsig.
7. Hlawv hlau
Tom qab carburising thiab quenchining, carburising steels zoo li 20Cr thiab 16MnCr5 yuav muaj HRc 58-63 ntawm cov hniav hardness nrog zoo heev hnav tsis kam thiab cuam tshuam tsis kam. Haum rau nruab nrab-load, siab ceev, cuam tshuam-loaded zog.
8. Hard aluminium
Txawm hais tias lub teeb thiab muaj zog heev, duraluminum yog ib qho muaj zog aluminium alloy cov khoom uas nws cov durability yog me ntsis tsis zoo piv rau tooj dag. Nws yog qhov tsim nyog rau cov iav nrog cov qauv hnyav.
9. Cov Hlau Hlau
Feem ntau siv rau kev nrawm nrawm thiab qis-load zog, grey cam khwb cia hlau yog nkig thiab muaj kev cuam tshuam tsis zoo; Txawm li cas los xij, nws muaj zog tsis kam mus rau kev sib koom tes thiab pitting.
10. tooj dag
Lub zog zoo thiab lub siab ntev ua tooj dag rau cov khoom hnyav thiab muaj zog hnyav, suav nrog cov khoom siv xws li cov khoom rov qab.
11. Cov khoom siv hmoov rau metallurgy
Nyob rau hauv qee qhov kev ua haujlwm tshwj xeeb, cov khoom siv hmoov metallurgy yog tsim nyog rau kev tsim cov iav thiab muaj lub zog zoo los ntawm sintering hmoov thiab ntxiv cov khoom tshwj xeeb.
Yuav ua li cas ib tug xaiv cov khoom siv iav uas tsim nyog nyob ntawm ntau yam kev ua haujlwm?
Cov xwm txheej siv tiag thiab cov xwm txheej thauj khoom yuav tsum coj cov xwm txheej tag nrho ntawm cov iav khoom xaiv.
45 steel feem ntau yog siv rau hauv lub teeb-loaded zog; nws yog ib qho normalized los yog tempered (quenching + high-temperature tempering), haum rau siv nrog lub teeb loads.
Feem ntau siv cov txiaj ntsig nruab nrab ua los ntawm 40cr steel, uas yog nto quenched ntawm cov khoom siv-resistant Cheebtsam thiab tempered.
Zog nrog kev thauj khoom siab: los lis cov khoom loj, ib qho yuav siv Carburised cov hlau zoo li 20crr thiab 20crmnti, uas yog quenched (martensite tempered thiab carburised.
Feem ntau siv tau yog 38crmooaia steel, tempered thiab nitrided los muab cov khoom raug thiab ntev ntev ua haujlwm.
Gear cov khoom xaiv hu rau kev txiav txim siab ntawm qhov loj me, gearbox precision, hniav hardness, thiab cov hniav core toughness. Xaiv cov khoom siv tau zoo tuaj yeem ua kom cov iav ua haujlwm tau zoo thiab ua kom nws lub neej ntev ntawm kev siv.
