Kev Xaiv Cov Pob Zeb Pob Zeb Bearings
Pob zeb mills tau dav siv hauv kev lag luam ntxhia thiab kev sib tsoo, thiab ua lub luag haujlwm tseem ceeb hauv cov txheej txheem ntawm cov ntxhia ua thiab sib tsoo, nrog rau cov yam ntxwv ntawm kev ceev ceev thiab hnyav.
Feem ntau siv bushing bearings rau kev khiav lag luam, vim hais tias ntawm lub siab load-nqa peev xwm yuav tsum tau, ib tug loj npaum li cas ntawm cov dej txias thiab lubricating roj yuav tsum tau, tus nqi kho mob yog siab, thiab cov teeb meem ntawm burning pads feem ntau tshwm sim vim txias thiab untimely lubrication.Ua rau nquag kaw, tsis ua haujlwm ntawm cov khoom siv hauv lub tog raj kheej, cuam tshuam rau kev tsim khoom thiab ua rau cov neeg siv poob hnyav.Vim tias lub pob zeb yog cov khoom siv loj, nws tus kheej tus nqi thiab cov ntaub ntawv uas nws grinds tau nyiaj ntau hauv cov txheej txheem ntau lawm.Kev ua haujlwm yuav tsum muaj kev ruaj ntseg.
Kev lig kev cai, peb feem ntau xaiv loj spherical roller bearings raws li kev daws teeb meem.
Spherical Ob Kab Kab Cov Menyuam Bearings
Taw qhia:Lub puab kheej kheej ob chav kab cov menyuam bearing muaj ib lub nplhaib sab nrauv nrog ob txoj kev sib tw, ib lub nplhaib puab ua ke, ob chav kab dov cov ntsiab lus thiab lub tawb.
Nta:Sab nraud spherical ob kab rau cov menyuam bearing muaj ob lub qauv: zawv zawg bearing thiab positioning bearing.Lub nplhaib sab nrauv muaj qhov sib txawv ntawm tus kheej, cov zawv zawg bearing bears siab radial load thiab tso cai rau axial zawv zawg, thiab qhov kawg qhov chaw kuj tuaj yeem dais bidirectional axial load thaum bearing tshwj xeeb loj radial load.Nws muaj peev xwm nqa tau loj.
Daim ntawv thov tseem ceeb:Hlau thiab steel kev lag luam → beneficiation pob zeb;cement kev lag luam → pob zeb, pob zeb qhuav;kev lag luam mining → mining pob zeb;ceramic kev lag luam → ceramic pob zeb.

Case Show
Keeb kwm:Pob zeb mills yog dav siv nyob rau hauv cov ntxhia ua thiab sib tsoo kev lag luam.Lawv txoj haujlwm yog pom tau los ntawm kev sib txhuam thiab zawv zawg ntawm lub hollow ncej thiab cov kabmob ncoo.Txawm li cas los xij, cov bearings ncoo yog siv nyob rau hauv tej yam kev mob uas muaj ib tug ntau ntawm cov plua plav, kev sib txhuam coefficient siab thiab siab kub, thiab bears qhov cuam tshuam ntawm lub tog raj kheej load, yog li cov bearings ncoo yog feem ntau puas.Phenomena xws li "cov vuas hlawv" cuam tshuam rau kev ua haujlwm ntawm lub pob zeb.
Cov neeg siv khoom keywords:kub kub, hnyav load, hlawv vuas, siab plua plav, nquag kaw, siab tu nqi.
01. Kev xaiv cov kabmob: NNU895Y3 ntawm qhov kawg pub, NNUP895Y3 ntawm qhov tso tawm kawg
Raws li cov neeg siv khoom ua haujlwm, lub pob zeb yog tsim los ntawm lub tog raj kheej, lub tog raj kheej kheej kheej, lub rooj zaum tseem ceeb, thiab cov kabmob bush.Lub axial quab yuam yuav raug tsim tawm thaum muaj kev thauj khoom, thiab cov kabmob uas muaj peev xwm loj yuav tsum tau xaiv.Peb tau tsim lub puab kheej kheej ob chav kab cov menyuam kabmob nrog lub peev xwm muaj zog, muaj kev cuam tshuam zoo, yooj yim lubrication, muaj kev ntseeg siab, ruaj rau lub tshuab sib tsoo, thiab tseem tuaj yeem ua haujlwm ib txwm thaum tsiv axially.Los ntawm kev suav lub neej, tsis muaj teeb meem hauv kev txheeb xyuas 43800 teev.
02. Tsim optimization:
Raws li tus neeg siv khoom lub luag haujlwm ua haujlwm:
1. Tus thawj pob zeb siv lub hollow ncej thiab cov kabmob bush rau zawv zawg kev sib txhuam kis tau tus mob, thiab cov roj nyias nyias ua cov roj zaj duab xis rau kev ncig lubrication.Hauv kev siv tiag tiag, raws li cov khoom siv nce, cov kabmob bush load nce.Yog hais tias cov cua sov uas tsim los ntawm kev sib txhuam tsis dissipated nyob rau hauv lub sij hawm, nws yuav tsim "Kub pobzeb" kev huam yuaj, yog li ntawd peb txhim kho cov zawv zawg kev sib txhuam ntawm cov bearing ncoo, saws lub dov kev sib txhuam tsim, thiab tsim ib tug ob chav kab menyuam bearing.
2. Lub pob zeb qhuav yuav elongate vim qhov kub siab ntawm cov khoom tuaj thiab qhov kub thiab txias tsim los ntawm kev ua haujlwm.Ua rau lub tog raj kheej lub cev txav mus rau ob qho kev taw qhia thiab khiav tsis ruaj khov.Yog li ntawd, kev txav thiab kev txhim kho ntawm lub tog raj kheej yog tsim, lub inlet yog tsim tsis muaj ribs, thiab lub qhov hluav taws xob yog tsim los ntawm ob sab tav, uas txaus siab rau qhov ruaj khov ntawm lub tog raj kheej.
3. Vim nws qhov hnyav thiab qhov cuam tshuam ntawm kev sib tsoo steel pob thiab steel forgings, lub tog raj kheej yog khoov thiab deformed los tsim deflection, uas yuav tsum tau cov kabmob dov los ua tus kheej, txwv tsis pub lub tog raj kheej tsis nyob hauv tib lub axis, ua rau hauv kev puas tsuaj rau cov kabmob.Yog li ntawd, peb tau tsim cov kev xav tau ntawm tus kheej ntawm cov kabmob dov.Lub nplhaib sab nraud ntawm lub nplhaib sab nraud ntawm cov kabmob yog tsim los rau hauv cov duab arc, uas daws qhov teeb meem ntawm lub tog raj kheej tawm ntawm kev sib tw.
03. Kev tshwm sim ua qauv qhia:
Los ntawm kev sib txuas cov kev siv ntawm cov khoom siv, peb tau tsim ib hom tshiab ntawm pob zeb bearing kom tau raws li cov neeg siv khoom xav tau.Lub sijhawm poob los ntawm cov neeg siv khoom "hluav taws kub ntawm cov vuas" ua txhaum yog txo qis, txuag cov neeg siv 80% -90% ntawm cov roj lubricating, tshaj 8% hluav taws xob, thiab kev txuag hluav taws xob ntau dua 10% -15%.Lub zog ntawm lub tshuab hluav taws xob siv hauv lub pob zeb tuaj yeem raug txo los ntawm 13% -20%, thiab lub peev xwm thauj khoom ntawm lub cev sib tsoo tuaj yeem nce los ntawm 15% -20%, txhim kho kev ua haujlwm ntawm lub pob zeb.
