Elastomeric Bearing Pad vs Laminated Roj Hmab Bearing: Qhov Tseem Ceeb Qhov Sib Txawv & Kev Siv
Hauv kev tsim choj thiab kev tsim vaj tsev, elastomeric bearings ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov qauv kev ua haujlwm, ua kom yooj yim txav, thiab txo qis kev vibrations. Ob hom kev siv feem ntau yogElastomer Bearing PadthiabLaminated Roj Hmab Bearing. Thaum lawv qhia cov haujlwm tseem ceeb zoo sib xws, lawv cov qauv tsim, kev ua tau zoo, thiab kev siv sib txawv. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau cov kws tshaj lij, cov neeg cog lus, thiab cov kws tshaj lij kev muag khoom los xaiv cov kabmob zoo rau lawv cov haujlwm-txawm nws yog tus choj me me lossis loj- qauv kev loj.
Dab tsi yog Elastomer Bearing Pads?
IbElastomer Bearing Pad(feem ntau hu ua ib qho yooj yim elastomeric bearing) yog ib qho yooj yim, tus nqi -cov kabmob muaj txiaj ntsig zoo ua los ntawm cov khoom siv elastomeric xws li roj hmab ntuj (NR) lossis chloroprene roj hmab (CR). Tsis zoo li cov kabmob muaj zog, feem ntau elastomeric bearing pads yogtsis muaj zog- txhais tau hais tias lawv muaj cov khoom siv roj hmab zoo sib xws, tsis muaj cov laminates sab hauv lossis lwm cov ntaub ntawv nruj.
Cov kabmob no feem ntau yog tsim los ua cov duab plaub lossis lub voj voos, yog molded tus kheej lossis txiav los ntawm cov roj hmab loj dua. Lawv cov qauv tsim tsom mus rau kev txhawb nqa yooj yim thiab kev txav txav tsis tshua muaj, ua rau lawv zoo tagnrho rau lub teeb - daim ntawv thov haujlwm. Cov yam ntxwv tseem ceeb ntawm elastomeric bearing pads muaj xws li:
Cov qauv yooj yim: Tsis muaj kev txhawb nqa steel sab hauv, ua rau lub teeb yuag thiab yooj yim -rau- nruab tsim.
Lub peev xwm ntsug ntsug nruab nrab: Haum rau me me - txuas txuas txuas, kev taug kev taug kev, thiab lub tsev teeb pom kev zoo uas cov khoom thauj tsis dhau.
Txwv tsis pub khiav tawm txoj kab rov tav: Vim tsis muaj cov hlau reinforcement, cov roj hmab yog nquag bulging nyob rau hauv load, txwv txoj kab rov tav txav thiab shear deformation.
Tus nqi-kev ua tau zoo: Raws li ib qho ntawm cov kev daws teeb meem kev lag luam tshaj plaws, lawv tau siv dav hauv cov peev nyiaj tsawg lossis kev tsim kho yooj yim.
Elastomeric bearing pads ua raws li cov qauv kev lag luam xws li ASTM D4014-23, uas tswj cov ntaub ntawv thiab kev ua tau zoo rau cov kabmob elastomeric dawb siv hauv cov txuas hniav. Lawv feem ntau siv rau hauv cov ntawv thov uas thermal expansion, contraction, los yog me me rotations yuav tsum tau haum yam tsis muaj complex engineering daws teeb meem.
Dab tsi yog Laminated Rubber Bearings?
A Laminated Roj Hmab Bearing(tseem hu ua steel-laminated elastomeric bearing) yog cov kabmob muaj zog uas tsim los rau hnyav-lub luag haujlwm, siab- kev ua haujlwm. Nws yog tsim los ntawm alternating txheej ntawm nyias elastomeric roj hmab los xij thiab nyias steel daim hlau, sib koom ua ke los ntawm siab - kub vulcanization los ua ib qho, nruj chav tsev. Cov hlau laminates ua haujlwm rau lub hom phiaj tseem ceeb: lawv tiv thaiv cov roj hmab los ntawm bulging nyob rau hauv ntsug loads, ua rau kom cov kabmob load-cov kabmob muaj peev xwm thaum tswj cov kab rov tav yooj.
Laminated roj hmab bearings yog engineered los tswj cov loads loj thiab ntau dua, ua rau lawv ib tug staple nyob rau hauv nruab nrab mus rau loj - ncua choj, siab - nce vaj tse, thiab seismic cais tej yaam num. Cov yam ntxwv tseem ceeb muaj xws li:
Reinforced qauv: Sab hauv steel daim hlau muab siab ntsug ntsug, tso cai rau cov kabmob los txhawb nqa cov txheej txheem hnyav yam tsis muaj compression ntau dhau.
Muaj peev xwm thauj khoom siab: Tsim los tiv thaiv qhov hnyav ntawm cov txuas hniav loj, cov tsev lag luam, thiab cov phiaj xwm kev tsim vaj tsev.
Txhim kho kab rov tav yooj yooj yim: Cov hlau daim hlau txwv cov roj hmab bulging, ua kom cov kabmob kom haum rau cov kab rov tav shear deformation tseem ceeb - zoo tagnrho rau kev sib cais seismic thiab cov qauv loj.
Durability: Lub vulcanized daim ntawv cog lus ntawm cov roj hmab thiab cov hlau ua kom ntev - kev ua tau zoo, txawm nyob rau hauv ib puag ncig hnyav, thiab ua raws li cov qauv kev lag luam nruj xws li EN 1337-3: 2005 thiab AASHTO specifications.
Qee lub sij hawm, laminated roj hmab bearings yuav suav nrog cov khoom siv ntxiv xws li PTFE zawv zawg qhov chaw lossis cov ntawv qhia steel los txhim kho lawv cov kev ua tau zoo rau cov kev siv tshwj xeeb, xws li txuas hniav nrog cov thermal txav loj.
Qhov sib txawv tseem ceeb ntawm Elastomeric Bearing Pad thiab Laminated Rubber Bearing
Txhawm rau pab koj paub qhov txawv ntawm ob hom kabmob no thiab txiav txim siab paub, peb tau sau cov ntsiab lus sib txawv hauv cov lus hauv qab no. Qhov kev sib piv no suav nrog cov qauv, kev ua tau zoo, kev siv, thiab kev ua raws li - yam tseem ceeb rau kev txiav txim siab engineering thiab kev yuav khoom.
