Lub luag hauj lwm ntawm Spring Bars nyob rau hauv lub Fastening System
Lub caij nplooj ntoos hlav bar (elastic strip) yog lub elastic clamping caij ntawm lub tsheb ciav hlau fastening system. Nws yog nias los yog tapped rau hauv lub xub pwg nyom ntawm lub fastening, thiab nws bent caj npab dais ntawm txoj kev tsheb ciav hlau ko taw, tsim ib tug nruam buckling quab yuam uas tuav lub tsheb ciav hlau thiab tiv thaiv lateral txav. Vim tias lub zog clamping los ntawm elastic deformation es tsis yog los ntawm kev nruj nruj, txoj kev tsheb ciav hlau tuaj yeem txav tau yooj yim nyob rau hauv qhov kev taw qhia longitudinal thaum lub sij hawm qhov kub thiab txias expansion, uas yog ib qho tseem ceeb ntawm kev txuas ntxiv welded rail. Caij nplooj ntoos hlav tuav yog cais los ntawm cov qauv, buckling quab yuam thiab cov ntaub ntawv qib, thiab txhua tus qauv yog tsim los rau ib tug tshwj xeeb kev pab cuam chav kawm ntawv los ntawm siab - ceev ballastless khiav mus rau hnyav - lub luag hauj lwm cov kab.
Core Model Classifications thiab Buckling Force
| Qauv | Buckling zog | Hom kev siv |
|---|---|---|
| W 2 typ | Tsawg kawg yog 10 kN | Siab -kev khiav ceev tsis muaj kev sib tw, kev kaw tsis tu ncua |
| X 3 typ | Tsawg kawg yog 3 kN | Tus qauv pab ua ke nrog W2, tsis tshua muaj kev tiv thaiv rau micro expansion |
| Hom I | Tsawg kawg yog 6 kN | Ordinary ballasted lub ntsiab kab, txheem ntsuas phoo |
| Hom II | Tsawg kawg yog 8 kN | Ordinary kab hnyav ceg, zoo cuam tshuam kuj |
| Heavy-lub luag hauj lwm thickened hom | Tsawg kawg yog 12 kN | Kev lag luam thiab mining hnyav lem, tiv thaiv -loosing thiab anti- yob |
Hom W2 yog lub ntsiab tseem ceeb siab - qauv nrawm nrog lub neej qaug zog tshaj 5 lab mus; hom X3 yog siv ua ke nrog W2 qhov twg rail micro- txav yuav tsum tsis txhob dhau - txwv. Hom I thiab Hom II npog cov kab zoo tib yam, thiab qhov hnyav - hom haujlwm siv ib ntu txog 30 feem pua thib dua los nqa lub zog siab dua ntawm kev tsuas thiab kev lag luam.
Cov khoom siv thiab qhov yuav tsum tau ua
Cov khoom siv tseem ceeb yog 60Si2Mn caij nplooj ntoos hlav steel, tau teev nrog lub zog tensile yam tsawg kawg nkaus ntawm 1275 MPa thiab lub zog tawm los ntawm tsawg kawg yog 1175 MPa raws li GB / T 1222. Rau siab -kev siv ceev, cov qib alloy siab dua xws li 60Si2CrVA raug xaiv rau lawv cov kev qaug zog zoo dua 8} vibration. Lub elastic rov qab los ntawm lub caij nplooj ntoos hlav tsim kom raug yog tiav: tom qab rov qab deflection nws rov qab mus rau cov qauv tsim, thiab nws yuav tsum dhau qhov kev sim qaug zog ntawm 5 lab lub voj voog uas tsis muaj pob txha los yog cov yas deformation mus tas li. Kev tiv thaiv saum npoo yog kub-dip galvanizing ntxiv rau passivation nrog txheej tuab ntawm tsawg kawg yog 65 microns thiab cov ntsev tsuag tshuaj tiv thaiv siab tshaj 400 teev, vim tias txheej txheej tawg yog qhov qub pib ntawm corrosion qaug zog hauv qhov chaw ntub dej.
Xauv Compatibility nrog Rails thiab Bolts
Lub caij nplooj ntoos hlav bar qhov yuav tsum haum rau txoj kev tsheb ciav hlau lub taub hau profile tsis muaj qhov khoob, yog li ntawd kev ntxhov siab txawm thiab lub bar tsis poob elasticity ntawm ib qho chaw sib cuag. Buckling quab yuam thiab ntsia liaj qhov rooj torque yuav tsum synchronized: W2 thiab X3 clips yog xauv nrog 10.9 qib bolts ntawm 500-550 Nm, Hom I thiab II nrog 8.8 qib bolts ntawm 350-400 Nm, thiab hnyav {{17} grade 600-650 Nm Yog hais tias tus ntsia liaj qhov rooj torque tsawg dhau, lub bar tsis tuaj yeem tsim nws tsim buckling quab yuam; yog tias siab dhau lawm, lub bar yog over-stressed ntawm tus ntiv taw thiab tej zaum yuav tawg. Lub bar yuav tsum zaum nruab nrab ntawm lub taub hau tsheb ciav hlau yam tsis muaj offset. Ntawm cov kab hluav taws xob, cov kab hluav taws xob siab ceev tau nruab nrog cov hlua khi thiab cov khoom siv hluav taws xob kom cov clip tsis tuaj yeem ua rau luv luv; zoo tib yam thiab muaj kab tuaj yeem ntsia tau yam tsis muaj rwb thaiv tsev.
Installation Rules thiab Txais
Tshawb xyuas txhua lub bar ua ntej kev teeb tsa rau kev deformation, xeb thiab tawg, thiab paub meej tias tus qauv sib tw rau kev tsheb nqaj hlau thiab ntsia liaj qhov rooj specification. Lub bar yog clamped rau hauv rail lub taub hau qhov nrog ib tug tshwj xeeb installation cuab yeej; Kev ua nruj ua tsiv tsis raug tso cai vim nws tuaj yeem cuam tshuam cov hlau thiab pib tawg. Tom qab kev teeb tsa, xyuas qhov elastic deflection: hom W2 yuav tsum deflect yam tsawg 12 hli thiab hom I yam tsawg kawg nkaus 8 hli nyob rau hauv qhov kev txiav txim xauv, uas yog pom pom tias buckling quab yuam yog tam sim no. Kev lees txais npog txhua qhov bar: tsis poob tawm, tsis muaj skew, tsis muaj loosening, thiab qhov sib nrug ntawm qhov kev sib tw yuav tsum tsis pub dhau 5 hli. Tom qab kev sim khiav, rov xyuas dua tias qhov elasticity tsis tau lwj thiab qhov kev tsheb ciav hlau tsis pom qhov nkag los yog txav mus rau sab nraud.
Common Faults thiab Maintenance
Elastic attenuation qhia tau hais tias txo buckling quab yuam thiab me ntsis rail creep; hloov nrog tib tus qauv thiab xyuas cov ntsia liaj qhov rooj torque tib lub sijhawm. Kev puas tsuaj feem ntau yog tshwm sim los ntawm kev qaug zog ntau dhau lossis cov khoom siv tsis raug; tshem tawm cov kab tawg, xyuas seb cov kab thauj khoom puas dhau tus nqi tsim, thiab hloov mus rau hom thickened ntawm hnyav - cov kab dej num. Xeb ua raws li txheej txheej puas thiab ya raws; Tom qab derusting thiab repainting, xav txog stainless hlau tuav nyob rau hauv ntug dej hiav txwv. Poob tawm cov txiaj ntsig los ntawm kev teeb tsa tsis zoo los yog hnav cov slots; re-clamp thiab ntxiv hnav- tiv thaiv gaskets qhov chaw hnav. Deformation los ntawm kev cuam tshuam sab nraud; kho lub bar yog tias ua tau, hloov nws yog tias tsis yog, thiab haum rau kev tiv thaiv - kev sib tsoo tiv thaiv qhov kev pheej hmoo siab heev.

FAQ
Kuv yuav xaiv li cas ntawm W2 thiab Hom II rau kev sib xyaw- kab tsheb khiav?
Xaiv los ntawm kev pabcuam hauv chav kawm: W2 yog tsim los rau siab -ceev ballastless khiav nrog nruam locking, thaum hom II suits ballasted kab uas muaj kev cuam tshuam ntau dua. Lub fastening system hom thiab rail profile txiav txim seb tus qauv haum.
Vim li cas bolt torque yuav tsum phim tus qauv clip?
Lub buckling quab yuam ntawm qhov clip yog tsim tawm tsam lub bolt preload. Lub zog tsis sib haum yog tawm ntawm qhov clip hauv qab -clamped, cia txoj kev tsheb ciav hlau nkag, lossis dhau - ntxhov siab ntiv taw, ua rau lub neej luv luv.
Dab tsi ua rau lub caij nplooj ntoo hlav tawg rau lub caij ntuj no?
Qhov kub thiab txias ua rau lub rhiab heev ntawm cov hlau, yog li txhua yam uas twb muaj lawm nto notch, txheej puas los yog dhau - torque mob yog feem ntau yuav xaus nyob rau hauv tawg. Txias- cov kab hauv cheeb tsam yuav tsum siv cov qhab nia nrog lav qis - qhov kub thiab txias toughness.
Puas yog lub caij nplooj ntoos hlav rusted tseem muaj kev nyab xeeb rau kev pabcuam?
Lub teeb nto xeb tuaj yeem derusted thiab repainted, tab sis pitting txo cov seem zoo thiab nce kev ntxhov siab. Cov tuav uas muaj feem tseem ceeb poob lossis ib qho tawg yuav tsum tau hloov tam sim ntawd.
Lub caij nplooj ntoos hlav tuaj yeem rov siv tau tom qab tshem tawm?
Tsuas yog tias lawv dhau qhov deflection thiab kev kuaj pom thiab tsis pom cov yas deformation. Nyob rau hauv kev xyaum feem ntau tshem tawm tuav yog hloov vim hais tias qaug zog keeb kwm tsis tuaj yeem soj ntsuam kev ntseeg siab hauv thaj teb.
