Khoom siv thiab fastening Performance ntawm Spring Rails
Dab tsi yog cov yam ntxwv tseem ceeb ntawm cov khoom siv feem ntau siv rau kev tsheb ciav hlau?
Rail clips feem ntau yog ua los ntawm boron steel lossis chromium-molybdenum alloy steel, uas muaj lub zog siab thiab muaj peev xwm rov qab tau zoo. Tom qab quenching thiab tempering kho cua sov, lawv lub zog tensile tuaj yeem ncav cuag tshaj 1400MPa, ua rau lawv tuaj yeem tiv taus ntev - lub sij hawm dynamic loads. Lub siab tawv ntawm cov khoom tuaj yeem tiv thaiv kev qaug zog ntawm kev sib tsoo ntawm cov tsheb ciav hlau thaum lub sij hawm nquag vibration thiab txuas ntxiv lawv lub neej kev pab cuam. Lub hauv paus tiv thaiv corrosion zoo, ua ke nrog kev tiv thaiv tom ntej - kev kho corrosion, tuaj yeem hloov mus rau qhov chaw sib txawv. Cov yam ntxwv no tso cai rau cov tsheb ciav hlau los muab lub zog clamping txaus thaum hloov mus rau micro- txav ntawm cov ntsia hlau.
Dab tsi cuam tshuam qhov preload ntawm rail clips muaj nyob rau hauv kev ruaj ntseg?
Lub preload ntawm rail clips yog qhov tseem ceeb rau kev kho cov ntsia hlau; txaus preload tuaj yeem nias cov ntsia hlau mus rau hauv qab - daim phiaj tsheb ciav hlau. Tsis txaus preload yuav ua rau lub attenuation ntawm clamping quab yuam, ua rau cov rails yooj yim mus rau longitudinal los yog transverse plam thiab cuam tshuam rau txoj hauj lwm geometric. Tsim nyog preload tuaj yeem ua kom ntseeg tau qhov ntev ntawm kev ua haujlwm siab dua lossis sib npaug ntawm 9kN thiab kev hloov pauv ntawm ntau dua lossis sib npaug rau 4kN, tiv thaiv qhov cuam tshuam los ntawm kev ua haujlwm tsheb ciav hlau. Uniform faib ntawm preload tuaj yeem zam qhov tsis sib xws hauv zos kev ntxhov siab ntawm cov ntsia hlau thiab txo qhov hnav thiab kev puas tsuaj. ruaj khov preload yog lub hauv paus tseem ceeb rau kev ua kom zoo thiab kev nyab xeeb ntawm kev ua haujlwm tsheb ciav hlau.
Dab tsi yog hom kev tsheb ciav hlau clips thiab lawv qhov sib txawv hauv daim ntawv thov scenarios?
Muaj ob hom kev tsheb ciav hlau clips: W-hom thiab e- hom, ob qho tib si yog cov tseem ceeb clamping Cheebtsam ntawm lub fastener system. W- hom kev tsheb ciav hlau clips muaj cov qauv compact thiab ruaj khov clamping quab yuam, thiab tau dav siv nyob rau hauv ballastless lem ntawm cov kev tsheb ciav hlau zoo tib yam thiab qee qhov siab - kev tsheb ciav hlau ceev. E- hom tsheb ciav hlau clips muaj kev ua haujlwm zoo dua qub thiab tuaj yeem hloov kho kom zoo dua rau cov thermal expansion thiab contraction hloov chaw ntawm cov ntsia hlau, ua rau lawv haum rau cov kab uas xav tau siab rau kev poob siab thiab elasticity. Ob qho tib si yuav tsum tau siv nrog cov khoom siv rwb thaiv tsev kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm lub voj voog khiav. Kev xaiv yuav tsum tau txiav txim siab raws li kab ceev, qag load thiab taug qab hom kom paub meej adaptability.
Dab tsi yog qhov ua rau qaug zog deformation ntawm rail clips?
Kev qaug zog deformation ntawm rail clips feem ntau yog tshwm sim los ntawm ntev - lub sij hawm dynamic cyclic loads generated los ntawm lub tsheb ciav hlau ua hauj lwm; rov nro thiab compression ua rau cov khoom qaug zog. Kev tsis zoo ntawm cov khoom nws tus kheej, xws li impurities thiab tawg, yuav ua rau kom qhov tshwm sim ntawm qaug zog deformation. Kev tswj lub zog tsis zoo thaum lub sijhawm teeb tsa ua rau muaj kev ntxhov siab, uas tseem txo qhov qaug zog ntawm kev tsheb ciav hlau clips. Ib puag ncig hnyav xws li qhov kub thiab txias, cov av noo siab thiab ntsev tsuag corrosion yuav ua rau cov khoom tsis muaj zog thiab ua rau qaug zog thaum ntxov. Yog tias txoj kab kev kho tsis raug raws sijhawm thiab cov kab tsheb ciav hlau nyob rau hauv lub xeev overloaded ntev, qaug zog deformation kuj yuav ua rau hnyav dua.
Yuav ua li cas los xyuas seb lub clamping quab yuam ntawm rail clips ua tau raws li tus qauv?
Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws yuav tsum muaj cov cuab yeej tshwj xeeb tshwj xeeb kom ntsuas cov clamping quab yuam. Nws tuaj yeem raug saib xyuas ncaj qha los ntawm kev soj ntsuam cov khoom siv; Yog hais tias txoj hauj lwm geometric feem ntau tshaj qhov txwv, nws yuav yog vim tsis txaus clamping quab yuam ntawm rail clips. Tsis tu ncua tshuaj xyuas qhov zoo li ntawm rail clips; Yog hais tias pom tseeb deformation, khoov los yog tawg, nws yuav ua tau nrog clamping quab yuam attenuation. Sib piv cov ntaub ntawv tus nqi torque ntawm qhov kev teeb tsa thawj zaug, thiab siv lub torque ciaj ntswj los tshuaj xyuas lub bolt zawm txheej xwm los txiav txim ncaj qha rau lub zog clamping. Thaum lub clamping quab yuam attenuation tshaj 15%, lub tsheb ciav hlau clips yuav tsum tau hloov nyob rau hauv lub sij hawm kom paub tseeb tias ua raws.
