Cov Khoom Siv Bearing Industrial Sab Saum Toj thiab Lawv Cov Kev Ua Tau Zoo Sib Piv

Vim li cas cov ntaub ntawv Bearing txiav txim siab qhov ua tau zoo thiab tag nrho cov nqi

Cov kws tshaj lij kev yuav khoom thiab cov pab pawg engineering paub tias kev xaiv cov khoom siv bearing tsis yog tsuas yog ib qho kev qhia tshwj xeeb xwb; nws yog tus tsav tsheb tseem ceeb ntawm kev ua haujlwm thiab Tag Nrho Tus Nqi ntawm Kev Muaj Tswv (TCO). Hauv kev siv hauv kev lag luam, tus nqi yuav thawj zaug ntawm cov bearing feem ntau sawv cev rau tsawg dua 15% ntawm nws cov nqi siv tas mus li. Kev ua tsis tiav ua ntej los ntawm cov lus qhia tsis raug ntawm cov khoom siv tuaj yeem ua rau lub sijhawm tsis ua haujlwm ntawm cov khoom siv, qhov twg kev hloov pauv thiab poob ntau zaus tshaj 10 txog 50 npaug ntawm tus nqi qub ntawm cov khoom. Yog li ntawd, cov neeg yuav khoom B2B yuav tsum soj ntsuam cov khoom siv tseem ceeb kom phim nrog lub neej qaug zog, lub sijhawm txij nkawm, thiab kev raug rau ib puag ncig.

Yuav Ua Li Cas Load, Speed, thiab Environment Cuam Tshuam Rau Kev Xaiv Khoom Siv

Cov yam ntxwv tseem ceeb uas ua rau cov khoom siv muaj sia nyob yog cov khoom siv dynamic load, rotational speed, thiab ambient operating conditions. Cov hlau bearing txheem zoo tshaj plaws nyob rau hauv cov khoom siv radial thiab axial siab tab sis raug kev puas tsuaj loj heev thaum qhov kub ua haujlwm tshaj 120 ° C (248 ° F) yam tsis muaj kev ruaj khov cua sov tshwj xeeb. Ntawm qhov tod tes, cov ntawv thov ceev ceev xav tau cov ntaub ntawv nrog qhov ceev qis dua thiab qhov nruj siab kom txo qis cov zog centrifugal ntawm cov khoom dov. Cov yam ntxwv ib puag ncig, tshwj xeeb tshaj yog kev raug rau cov tshuaj corrosive, noo noo, lossis cov xwm txheej nqus tsev, tam sim ntawd tsis tsim nyog cov hlau carbon siab, yuav tsum tau hloov mus rau cov hlau alloyed lossis tsis yog hlau lwm txoj hauv kev kom tiv thaiv kev oxidation sai thiab spalling.

Cov Qauv Xaiv Twg Tseem Ceeb Tshaj Plaws rau Cov Neeg Yuav Khoom OEM

Rau Cov Chaw Tsim Khoom Siv Thawj (OEMs), cov qauv xaiv txuas ntxiv mus dhau qhov ntsuas qhov hnyav yooj yim (Cr) thiab lub peev xwm thauj khoom zoo li qub (Cor). Cov pab pawg yuav khoom muab qhov tseem ceeb rau lub neej qaug zog L10 - qhov ntsuas suav qhia tias 90% ntawm cov neeg nqa khoom yuav ntsib lossis tshaj qhov teev tseg ntawm kev hloov pauv ua ntej thawj qhov pov thawj ntawm kev qaug zog flaking. Cov neeg yuav khoom kuj tseem yuav tsum soj ntsuam qhov ruaj khov ntawm cov khoom siv dhau sijhawm, nws qhov sib xws nrog cov roj nplua nyeem tshwj xeeb, thiab nws cov qauv suab. Hauv cov ntawv thov xws li lub tsheb alternators lossis cov cav hluav taws xob precision, suab nrov, kev co, thiab kev hnyav (NVH) ntsuas yog qhov tseem ceeb, xav tau cov ntaub ntawv uas tuaj yeem sib tsoo thiab honed rau qhov tiav ntawm qhov chaw nruj heev.

Cov Khoom Siv Bearing Industrial Piv Txwv Li Cas

Kev tshawb nrhiav txog cov khoom siv bearing hauv kev lag luam yuav tsum muaj kev nkag siab sib piv txog metallurgy thiab polymer science. Cov chaw tsim khoom tsim cov alloys thiab cov sib xyaw tshwj xeeb los daws cov teeb meem sib txawv ntawm kev siv tshuab, sib npaug qhov nyuaj, qhov tawg, thiab tus nqi.

Chrome Hlau vs Stainless Hlau vs Ceramic

Cov hlau chrome uas muaj cov pa roj carbon ntau, feem ntau yog SAE 52100 lossis GCr15, tseem yog tus qauv kev lag luam, suav rau feem ntau ntawmkev lag luam bearings. Nws muaj lub zog qaug zog thiab hnav tsis kam zoo, feem ntau yog kho cua sov rau qhov nyuaj ntawm 60 txog 64 HRC. Txawm li cas los xij, nws cov ntsiab lus chromium qis ua rau nws yooj yim rau xeb. Thaum qhov kev tiv thaiv corrosion yog qhov tseem ceeb, 440C stainless hlau yog teev tseg. Thaum 440C tiv taus cov dej noo thiab cov tshuaj lom neeg me me, nws txi qee qhov peev xwm thauj khoom vim qhov nyuaj siab tshaj plaws me ntsis (58 txog 60 HRC) thiab nqa tus nqi them ntawm kwv yees li 30% txog 50% dua li chrome hlau. Rau qhov chaw ib puag ncig hnyav, cov ntaub ntawv ceramic - tshwj xeeb tshaj yog Silicon Nitride (Si3N4) - siv. Cov khoom siv ceramic dov muaj qhov ceev ntawm 3.2 g / cm³ (kwv yees li 40% ntawm cov hlau), txo cov centrifugal loads ntawm qhov ceev ceev, thiab tuaj yeem ua haujlwm tas li ntawm qhov kub tshaj 800 ° C.

Thaum Twg Yuav Tsum Siv Cov Khoom Siv Bronze, Polymer, thiab Cov Khoom Siv Self-Lubricating

Ntxiv rau cov kabmob dov, cov kabmob tiaj tus thiab cov bushings vam khom ntau rau cov tooj liab, cov polymers tsim, thiab cov hlau sintered. Cov hlau tooj liab cam khwb cia thiab cov hlau alloys ua tau zoo hauv kev siv siab, qis ceev uas raug rau cov khoom hnyav, xws li cov tshuab ua liaj ua teb thiab cov khoom siv hauv kev tsim kho hnyav. Cov polymers tsim, suav nrog PTFE thiab PEEK, muab kev tiv thaiv tshuaj lom neeg zoo heev thiab zoo tagnrho rau cov chaw ntxuav hauv kev ua zaub mov uas txwv tsis pub siv roj. Cov kabmob tooj liab lossis hlau sintered, roj-impregnated muabcov khoom siv lubricating tus kheejlos ntawm kev ua haujlwm ntawm cov hlab ntsha. Cov khoom siv uas muaj qhov ntxeem tau no feem ntau tuav tau 15% txog 20% ​​roj los ntawm qhov ntim, ua rau lawv yog cov kev daws teeb meem uas tsis tas yuav saib xyuas rau cov cav me me thiab cov khoom siv hauv tsev, yog tias cov kev txwv ntawm Pressure-Velocity (PV) ntawm cov khoom siv raug ua raws li nruj me ntsis.
