R65 rail yog dab tsi?
CovR65 railyog ib qho hnyav - lub luag haujlwm railway rail profile tsim raws li Lavxias teb sab GOST tus qauv, tshwj xeeb tshaj yog GOST R 51685 (thiab laus dua GOST 8161 cov cai). Tus cwj pwm los ntawm qhov hnyav ntawm kwv yees li 64.88 kilograms ib 'meter', nws ua haujlwm raws li cov pob txha ntawm siab - muaj peev xwm thauj mus los thoob plaws hauv Lavxias tus qauv kev tsheb nqaj hlau, Lub Tebchaws Tebchaws ywj pheej (CIS), thiab Baltic tes hauj lwm. Nws yog engineered los tiv thaiv siab axle loads, hnyav dynamic kev nyuaj siab, thiab huab cua kub hloov nyob rau hauv hnyav freight thiab neeg nrog caij rail kab.
Txhawm rau ua kom tiav ntev - lub sij hawm taug qab kev ruaj ntseg thiab kev ua haujlwm zoo raws li kev xav tau ntawm kev ua haujlwm, qhov profile no suav nrog cov khoom zoo geometric thiab metallurgical:
- Optimized Mass Distribution:Nrog rau qhov hnyav ntawm 64.88 kg / m, 65 kg / m hnyav tsheb ciav hlau muab kev thauj khoom zoo heev - cov kabmob muaj peev xwm thiab txo qis kev deformation nyob rau hauv cov tsheb thauj khoom hnyav.
- Standardized Metallurgy:Tsim los ntawm qib siab - carbon steel qib zoo li M76T, K76F, lossis E76F, kom ntseeg tau zoo heev hnav tsis kam, siab tensile zog, thiab kev sib cuag zoo dua - kev ua haujlwm qaug zog.
- Geometric Precision:Lub Profile R65 rail nta ib lub hauv paus dav dav kom faib cov ntsug quab yuam zoo rau cov neeg pw tsaug zog, lub vev xaib tuab los tiv thaiv lub lateral buckling, thiab lub taub hau zoo profile optimized rau lub log -rail kev sib tshuam.
Kev soj ntsuam tas li ntawm qhov raug ntau lawm, kuaj ultrasonic rau sab hauv qhov tsis zoo, thiab ua raws li tus qauv Lavxias GOST P51685 kom ntseeg tau tias txhua qhov ntev xa tuaj raws li cov kev xav tau ntawm cov tshuab xav tau rau kev ua haujlwm hnyav -.GNEE RAILtswj xyuas cov txheej txheem siab tshaj steel refining thiab meej dov tolerances los lav cov khoom txhim khu kev qha uas muaj peev xwm ua kom muaj kev ruaj ntseg ntawm ntau txhiab tons ntawm kev khiav tsheb.
Dab tsi yog Cov Ntsiab Lus Tsim Cov Qauv thiab R65 Rail Dimensions?
Cov txheej txheem kev ncaj ncees ntawm qhov hnyav - txoj haujlwm railway rail profile nyob ntawm tag nrho cov kev ntsuas geometric, uas tiv thaiv kev ntxhov siab hauv cheeb tsam thiab lub log tsis sib xws.

Cov qauv zoo ntawm Profile R65 rail
GOST-txheej txheem R65 (P65) rail profile yog tsim tshwj xeeb rau hnyav-haul, siab- cov kab loj thiab cov kab uas raug mob hnyav heev. Nws cov duab geometry muab qhov zoo tshaj plaws kev faib tawm ntawm cov hlau kom sib npaug ntsug ntsug, kev ruaj ntseg sab nraud, thiab ntev - lub sij hawm hnav tsis kam.
Thawj qhov zoo ntawm cov qauv R65 rail profile suav nrog:
High Moment ntawm Inertia thiab dabtsi yog khoov nruj
Lub R65 profile nta ib tug ntoo khaub lig- cheeb tsam cheeb tsam thiab loj tis tsim los ua kom lub sij hawm ntawm inertia raws li kab rov tav (Ix) axis.
- Deflection Resistance:Lub vev xaib sib sib zog nqus thiab lub taub hau loj tso cai rau txoj kev tsheb ciav hlau tuaj yeem tiv thaiv txoj kab ntsug hauv qab lub nra hnyav (feem ntau ntsuas rau 25-30 tonnes lossis ntau dua). Qhov no txo qis nthwv dej-zoo li deflection ua ntej ntawm lub log dov, txo lub zog poob thiab kev ntxhov siab ntawm lub txaj ballast.
- Load Distribution:Siab ntsug nruj kom ntseeg tau tias cov tsheb thauj khoom hnyav tau muab faib ua ntau dua ntawm cov neeg pw tsaug zog, txo cov kev ntxhov siab hauv cheeb tsam ntawm kev sib tw khiav.
Optimized Mass - rau - Qhov siab piv
Qhov hnyav kwv yees li64,88 kg / m, qhov profile sib npaug cov khoom siv raw nrog qhov siab geometrical (180 mm).
- Qhov siab tshwj xeeb no ua kom muaj kev nruj txaus thaum ua kom qhov nruab nrab ntawm lub ntiajteb txawj nqus tsawg txaus los tiv thaiv torsional twisting lossis rail overturning nyob rau hauv siab lateral rog (piv txwv li, nyob rau hauv nruj nkhaus).
Reinforced Head Geometry rau Hnav Ntev
Lub taub hau ntawm R65 rail yog dav (75mm ua) thiab sib sib zog nqus, nrog rau qhov sib txawv profile optimized rau log -rail contact mechanics.
- Tiv tauj kom txo kev ntxhov siab:Qhov dav sab saum toj radius conforms zoo rau tus qauv tsheb ciav hlau log profiles, maximizing thaj chaw tiv tauj. Qhov no txo qis kev sib cuag nrog kev ntxhov siab, ncua qhov pib ntawm dov kev sib cuag qaug zog (RCF), kev sib tsoo, thiab cov yas deformation.
- Sacrificial Wear Volume:Cov txheej txheem qhov tob ntawm lub taub hau muab lub ntim loj ntawm cov hlau siv tau rau sab ntsug thiab sab sab - hnav ua ntej txoj kev tsheb ciav hlau mus txog nws qhov kev txwv tsis pub siv, txuas rau tag nrho cov kev pabcuam lub neej.
| Metric / Feature | R65 Cov Qauv Dimension | Primary Engineering Benefit |
| Tag nrho qhov siab | 180 mm | Maximizes ntsug dabtsi yog khoov nruj; thiaj li khiav deflection. |
| Lub hauv paus dav | 150 hli | Muab lateral stability; txo qhov siab ntawm cov pw tsaug zog / fasteners. |
| Lub taub hau dav | 75mm ua | Optimizes log tiv tauj cheeb tsam; nce muaj hnav ntim. |
| Web Thickness | 18 hli | Resistant shear stress; tiv thaiv longitudinal cracking thiab buckling. |
| Linear Mass | ≈ 64.88 kg / m | Muab cov qauv kev ntseeg siab uas xav tau rau kev ua haujlwm hnyav - thauj. |
