Tsheb lub sij hawm chains feem ntau yog ua los ntawm cov ntaub ntawv alloy. Nov yog cov lus piav qhia ntxaws ntxaws ntawm cov ntaub ntawv siv hauv tsheb lub sij hawm chains:
Cov ntaub ntawv tseem ceeb
Cov khoom siv feem ntau siv rau lub sijhawm tsheb chains yog hlau alloy. Cov khoom no ua rau nws muaj zog thiab hnav tsis kam los ntawm kev ntxiv cov ntsiab lus alloying, xws li chromium (Cr) thiab molybdenum (Mo). Piv txwv li, 40CrNiMoA steel yog ib qho uas feem ntau siv siab - lub zog alloy steel nrog lub zog tensile tshaj 2000 MPa, ua rau nws zoo tagnrho rau kev tsim tsheb caij tsheb chains uas yuav tsum tau tiv taus siab loads thiab high speeds.
Lwm yam khoom siv
Dhau li ntawm cov hlau alloy, tsheb lub sij hawm chains kuj tau siv cov hlau tsis muaj steel thiab cov ntaub ntawv sib xyaw, tab sis cov ntaub ntawv no siv tsawg dua. Stainless hlau, xws li 304 lossis 316 stainless hlau, muaj kev tiv thaiv corrosion zoo heev thiab siab - kub tsis kam, tab sis nws lub zog thiab hnav tsis kam yuav tsis zoo li hlau alloy. Cov ntaub ntawv sib xyaw, xws li carbon fiber reinforced polymers, yog lub teeb yuag thiab siab - lub zog, tab sis lawv kim dua thiab muaj cov txheej txheem tsim ntau dua, yog li lawv tsis siv dav hauv kev xyaum.
Qhov tseem ceeb ntawm kev xaiv cov khoom
Kev xaiv ntawm cov khoom siv rau lub caij tsheb kauj vab yog qhov tseem ceeb rau lawv cov kev ua tau zoo thiab kev ua neej nyob. Cov ntaub ntawv tsim nyog ua kom ruaj khov kev sib kis tau zoo thiab qhov tseeb thaum lub sijhawm ua haujlwm siab - nrawm, thaum txo qis hnav thiab ua haujlwm tsis zoo. Yog li ntawd, nyob rau hauv cov txheej txheem tsim tsheb, cov khoom siv saw hlau tsim nyog raug xaiv raws li cov kev xav tau tshwj xeeb thiab kev ua haujlwm ntawm lub tsheb.
