Kev rhuav tshem ntawm tus ncej thiab cov khoom siv coj los siv
Taw qhia
Cov kauj vuam yog cov khoom uas muaj cylindrical uas hnav nyob hauv nruab nrab ntawm cov kabmob, lub log, lossis lub iav, tab sis ib qho me me yog square. Ib tus hlau yog cov khoom siv ua tshuab uas txhawb thiab tig nrog ib qho kev sib hloov los xa cov lus tsa suab, lub zog, lossis khoov lub sijhawm. Feem ntau puag ncig cov kav hlau, txhua ntu tuaj yeem muaj cov diameters sib txawv. Qhov ntawm cov tshuab hauv tshuab uas ua cov lus teb tig tau ntsia ntawm tus ncej. 
Kev siv cov ntaub ntawv
1.Txiav phom steel
Cov pa roj carbon monoxide zoo cov qauv xws li 35, 45, thiab 50 muaj ntau daim ntawv thov vim tias lawv lub zog ua txhua yam muaj zog. Ntawm lawv, 45 steel yog qhov feem ntau siv.
Txhawm rau txhawm rau txhim kho nws cov yam ntxwv lub cev, nws yuav tsum ua kom zoo li qub los yog quenched thiab tempered. Rau cov shafts uas tsis tseem ceeb lossis raug rau cov tub rog me, cov txheej txheem carbon hlau xws li Q235 thiab Q275 tuaj yeem siv.
2.Alloy hlau
Alloy hlau muaj cov cuab yeej siab dua, tab sis kim dua, thiab feem ntau siv rau kev ua haujlwm nrog cov kev cai tshwj xeeb.
Piv txwv li, cov xwm txheej siab uas siv zawv zawg hluav taws xob feem ntau yog cov pa roj carbon hlau me me uas muaj cov kav hlau loj xws li 20Cr thiab 20CrMnTi. Tom qab carburizing thiab quenching, phau ntawv xov xwm hnav tsis kam tuaj yeem hloov kho;
Turbine lub tshuab hluav taws xob rotor ua haujlwm tau zoo nyob rau hauv qhov kub thiab txias, kev kub ceev, thiab lub nra hnyav, thiab yuav tsum muaj qhov kub thiab txias tsis zoo rau cov khoom siv, feem ntau siv 40CrNi, 38CrMoAlA thiab lwm cov hlau txheej txheem hlau.
Kev zam txim ntawm cov ntoo yog muab qhov muaj feem thib rau kev ua txhaum, tom qab los ntawm cov hlau puag ncig;
Cov ntau thiab tsawg lossis cov qauv ua haujlwm tuaj yeem txiav txim siab cov hlau nrum lossis cov hlau ua kom hlau.
Piv txwv, kev tsim khoom ntawm crankshafts thiab camshafts nrog nodular cam khwb cia hlau muaj qhov zoo ntawm tus nqi qis, zoo kev co kev co, tsis tshua muaj siab rau kev ntxhov siab concentration, thiab lub zog zoo.
Tus qauv kho tshuab ntawm tus ncej yog ib lub nqaj, feem ntau ntawm nws tig, yog li nws qhov kev ntxhov siab feem ntau yog lub voj voog uas muaj sib luag.
Cov ntawv tuaj yeem ua tsis tiav yog: qaug zog dhau, ua kom tawg, ua haujlwm ntau dhau ntawm elastic deformation, thiab lwm yam.
Qee qhov chaw nrog lub hub yog feem ntau ntsia rau ntawm tus ncej, yog li feem ntau cov shaft yuav tsum tau ua rau hauv cov kab nrig uas muaj qhov txiav ntau.
