Ntev npaum li cas yog 115 lb rail?

Yog tias koj tab tom npaj ib txoj haujlwm kev tsheb ciav hlau, nrhiav cov khoom siv rau kev lag luam sab nrauv, lossis tuav cov kev hnyav-, kev nkag siab txog qhov ntev ntawm koj qhov kev tsheb ciav hlau yog qhov tseem ceeb.

Cov lus teb luv luv yog: Astandard 115 lb rail (tseem hu ua 115 RE rail) yog raws nraim6-5/8 nti siab, uas yog sib npaug rau168.3mm 3(los yog 168.28 mm).

Hauv qab no, peb muab cov txheej txheem ua tiav ntawm 115 RE rail seem, nws cov qauv kev zam, cov khoom siv tau zoo, thiab cov kev xav txog kev teeb tsa raws li AREMA cov qauv.

Rau kev siv ceev, cov lus hauv qab no qhia txog qhov loj me me ntawm tus qauv 115 RE rail nyob rau hauv ob qho tib si imperial (inch) thiab metric (millimeters) units.

Cov Lus Qhia Tshwj Xeeb (115 RE)

Txhawm rau ua kom lub log kom zoo -rail interface thiab taug qab kev ruaj ntseg, railway engineers cia siab rau cov ntsiab lus curvature thiab nqes hav. Thaum tshuaj xyuas tus qauv 115 RE rail seem kos duab, ntau cov ntsiab lus geometric tseem ceeb yog qhov tseem ceeb:

• Lub taub hau Geometry:Qhov chaw khiav dej num nta lub vojvoog tseem ceeb pib nrog R203.2 hli (8 nti) ntawm qhov chaw saum toj kawg nkaus, hloov mus rau R44.5 hli (1.75 nti) ntawm cov ces kaum, thiab R14.3 hli (0.56 ntiv tes) ntawm cov ces kaum sab. Qhov tshwj xeeb contour no yog tsim los txo cov log thawj zaug -rail contact stress.

• Sab Slopes:Ob sab ntawm lub taub hau tsheb ciav hlau muaj me ntsis taper ntawm 1:40, uas pab coj lub log flanges smoothly.

• Nuv Ntses Angles (Slopes nyob rau hauv lub taub hau thiab sab saum toj ntawm lub hauv paus):Ob qho tib si hauv qab ntawm lub taub hau thiab saum npoo ntawm lub hauv paus flange muaj txoj kab nqes 1: 4. Cov chaw tiaj tus, lub kaum sab xis (lub npe hu ua qhov chaw nuv ntses) yog qhov tseem ceeb vim tias lawv tuav cov tuav sib koom ua ke (fishplates) thiab yuav tsum ua kom haum rau lawv kom tsis txhob muaj kev sib koom ua ke los yog ntsug.

• Web Design:Lub vev xaib yog 15.9 hli (5/8 ") tuab ntawm nws qhov nqaim tshaj plaws, nrog rau kev hloov pauv cov kab hluav taws xob ntawm R19.05 hli thiab R355.6 hli los faib cov khoom sib npaug thiab txo qis kev ntxhov siab.

Hauv North American railway terminology, rails raug cais los ntawm lawv qhov hnyav ib mev ntawm qhov ntev. Thaum feem ntau sib npaug thiab hu ua "115 lb rail," qhov tseeb theoretical qhov hnyav ntawm 115 RE profile yog114.7 lbs ib yard(kwv yees56.9 kg ib 'meter').

Qhov kev xaiv "RE" qhia tau hais tias qhov profile yog tsim los ua raws li cov lus qhia tshwj xeeb ntawm covAmerican Railway Engineering thiab Maintenance- ntawm -Txoj Kev Koom Tes (AREMA). Hauv qee cov qauv thoob ntiaj teb lossis cov lus nyob sab Europe, qhov profile no kuj raug xaiv los uaTSI TR57vim nws cov linear loj nyob ze rau 57 kg/m.

1. Puas yog 115 RE rail tuaj yeem koom nrog 136 RE rail?

Yog lawm, tab sis lawv tsis tuaj yeem koom nrog cov qauv sib koom ua ke vim qhov sib txawv ntawm qhov siab tag nrho (168.3 hli rau 115 RE vs . 185.7 hli rau 136 RE). Kev koom nrog lawv yuav tsum tau tshwj xeeb Kev Sib Txuas Sib Koom Tes Bars lossis kev hloov pauv vuam kom ntseeg tau tias muaj kev sib hloov, theem ntawm kev khiav haujlwm.

2. Tus qauv ntev ntawm 115 lb rail yog dab tsi?

Hauv North American tus qauv kev coj ua, cov tsheb ciav hlau tshiab feem ntau yog xa hauv 39-ko taw lossis 80-foot ntev. Txawm li cas los xij, rau kev thauj mus los thoob ntiaj teb lossis cov chaw tshwj xeeb, lawv tuaj yeem raug txiav rau qhov ntev xws li 12 meters, 25 meters, lossis lwm qhov ntev.

3. Kuv yuav ua li cas thiaj paub yog tias kuv xav tau tus qauv carbon lossis lub taub hau -hardened 115 RE rail?

Standard carbon rails feem ntau txaus rau kev ncaj tangent lem nrog lub teeb rau nruab nrab tsheb. Yog tias koj txoj kab tsheb ciav hlau muaj qhov nkhaus nkhaus dua li 3 lossis 4 degrees, lossis yog tias nws nqa siab -tonnage freight ntau zaus, lub taub hau- cov hlua tawv tawv feem ntau nyiam los tiv thaiv kev hnav ntsug thiab cov yas deformation.
