Qhov twg zoo dua: cam khwb cia hlau rooj lossis cam khwb cia hlau rooj?
Thaum cov cav tov loj hauv cov chaw ua haujlwm khiav, muaj cov khoom tseem ceeb uas ua lub luag haujlwm tseem ceeb nyob ntsiag to, uas yog lub rooj zaum bearing. Cov rooj zaum bearing yog qhov tseem ceeb rau cov cranes nqa cov khoom hnyav thiab cov cuab yeej siv tshuab kom raug txiav qhov chaw. Lawv khov kho txhawb cov bearings thiab xyuas kom meej kev ua haujlwm du ntawm cov tshuab. Cov ntaub ntawv ntawm lub rooj zaum yog cam khwb cia hlau thiab cam khwb cia hlau. Yog tias koj raug nug kom xaiv, koj puas paub qhov twg yog qhov zoo dua rau cov rooj zaum bearing?
Cam khwb cia hlau bearing lub rooj: qis-tus yuam sij "tus huab tais ntawm tus nqi-effectiveness"
(I) Tus nqi kom zoo dua
Cam khwb cia hlau zoo li "kev lag luam thiab kev siv" hauv kev lag luam rooj tog. Los ntawm qhov kev xav ntawm cov khoom siv, nws tus nqi yog pheej yig heev. Hauv kev ua lag luam, tus nqi ntawm cov cam khwb cia hlau feem ntau qis dua li ntawm cov hlau cam khwb cia, uas tuaj yeem txuag nqi rau cov tuam txhab tsim cov rooj tog zaum ntawm qhov loj. Ntxiv mus, cov txheej txheem ntawm cov hlau cam khwb cia yog qhov yooj yim heev thiab tsis tas yuav siv cov cuab yeej nyuaj heev thiab cov khoom siv siab - kawg. Qee qhov chaw ua haujlwm me me tuaj yeem siv cov txheej txheem xuab zeb casting los tig cov ntaub ntawv hlau cam khwb cia rau hauv cov khoom tsim nyog rau lub rooj zaum blanks, uas txo cov nqi ntau lawm.
(II) Kev ua haujlwm zoo
Hardness thiab hnav tsis kam: Txawm hais tias cam khwb cia hlau muaj tus nqi qis, nws hardness tsis tsawg. Nyob rau hauv qis- nrawm thiab lub teeb- thauj khoom ua haujlwm, qhov hnav tsis kam ntawm cam khwb cia hlau bearing rooj yog qhov zoo heev. Piv txwv li, nyob rau hauv ib co me me motors, lub rooj zaum bearing muaj ib tug tsawg ceev thiab tsis nyob rau hauv lub siab zoo. Cam khwb cia hlau tuaj yeem tiv thaiv kev sib txhuam zoo nrog nws qhov siab hardness, thiab ruaj khov txhawb nqa cov kabmob ntev ntev kom ntseeg tau tias lub cev ua haujlwm ib txwm muaj. Ntxiv mus, grey cam khwb cia hlau muaj flake graphite, uas zoo li ib tug natural lubricant. Rau qee qhov, nws kuj tseem txhim kho qhov hnav tsis kam ntawm cam khwb cia hlau, ua kom nws zoo dua thaum khiav ntawm qhov ceev.
Brittle shortcoming. Qhov loj tshaj qhov tsis zoo ntawm cam khwb cia hlau yog nws qhov tsis zoo toughness thiab brittleness. Thaum nws raug kev cuam tshuam loj, nws yooj yim tawg. Piv txwv li, thaum lub sij hawm kev thauj mus los, yog tias muaj kev sib tsoo, lub rooj zaum hlau cam khwb cia yuav tawg lossis tawg ncaj qha. Thaum txiav, nws cov yam ntxwv nyuaj thiab nkig muaj ob qho zoo thiab qhov tsis zoo. Qhov zoo dua yog tias cov chips yooj yim tawg thaum txiav, thiab kev ua haujlwm kuj yooj yim; tab sis qhov tsis zoo yog tias thaum lub sijhawm ua haujlwm, yog tias kev ua haujlwm tsis raug, nws yog ib qho yooj yim uas yuav ua rau muaj qhov tsis xws luag xws li ntug vau ntawm qhov chaw, cuam tshuam rau cov khoom zoo.
(III) Cov xwm txheej siv tau
Cam khwb cia hlau bearing rooj yog dav siv nyob rau hauv qis -ceev, lub teeb -load thiab tsawg- qhov tseeb scenarios. Hauv kev ua liaj ua teb me me, xws li me me seeders thiab threshers (xws li: UC204, UC205), cov cuab yeej no muaj qhov ceev ceev thaum ua haujlwm, thiab cov kev xav tau ntawm cov rooj zaum bearing tsis nruj tshwj xeeb. Cam khwb cia hlau bearing rooj tau dhau los ua qhov kev xaiv zoo tshaj plaws vim lawv cov nqi qis thiab muaj peev xwm ua tau raws li cov kev xav tau yooj yim, pab cov neeg ua liaj ua teb ua tiav kev ua liaj ua teb ntawm tus nqi qis. Hauv qee cov khoom siv kab ntau lawm, xws li cov khoom ntim khoom noj me me, cov khoom siv ua haujlwm qeeb. Cam khwb cia hlau bearing rooj yuav stably txhawb cov bearings, xyuas kom meej lub lag luam ntawm cov kab ntau lawm, thiab txuag cov khoom siv rau cov lag luam. Piv txwv li, feem ntau yog UCP205.
Cast steel bearing seat: "tag nrho-rounder" nrog lub zog
(I) Superior mechanical zog
Cast steel bearing seats tuaj yeem hu ua "tus txiv neej muaj zog" hauv kev lag luam rooj tog, nrog lub zog super. Nws muaj zog heev thiab tuaj yeem tiv taus siab loj yam tsis muaj deformation. Piv txwv li, nyob rau hauv ib tug loj crane, thaum nws lifts kaum ob tons ntawm cargo, cam khwb cia hlau bearing lub rooj yuav tsis tu ncua txhawb tag nrho cov system, thiab nrog nws tus kheej siab lub zog, nws yuav yooj yim tiv nrog cov hnyav load. Ntxiv mus, cam khwb cia hlau muaj zoo heev toughness thiab ductility, uas txhais tau hais tias nws yuav tsis tawg yooj yim thaum nws cuam tshuam los ntawm sab nraud rog, thiab muaj peev xwm tsis muaj zog los ntawm nws tus kheej deformation. Txawm hais tias muaj kev cuam tshuam tsis zoo, cov cam khwb cia steel bearing lub rooj tuaj yeem tswj tau qhov kev ncaj ncees ntawm cov qauv thiab txuas ntxiv mus ua haujlwm ib txwm, txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom siv.
(II) Cov yam ntxwv ua haujlwm
Thaum ua cov cam khwb cia steel bearing rooj, nws txawv txawv ntawm cam khwb cia hlau. Cam khwb cia hlau muaj qhov hardness tsawg, tab sis zoo toughness, uas ua rau nws nyuaj rau cov chips tawg thaum txiav, thiab feem ntau ua ntev strips. Qhov ntev nti no yooj yim los qhwv ib ncig ntawm lub cuab yeej thaum lub sij hawm ua, uas yuav tsis tsuas yog ua rau kom cov txiav tsis kam, tab sis kuj yuav cuam tshuam rau kev ua hauj lwm raug thiab txawm ua puas lub cuab tam. Yog li ntawd, thaum ua cov cam khwb cia steel bearing rooj, cov kev xav tau rau cov cuab yeej yog siab dua, thiab sharper thiab hnav ntau dua -cov cuab yeej resistant yuav tsum tau xaiv, thiab cov kev txiav yuav tsum tau kho kom haum, xws li txo qhov txiav ceev, nce tus nqi noj, thiab lwm yam, kom txo tau qhov cuam tshuam ntawm chips ntawm kev ua. Nyob rau tib lub sijhawm, cov kua txiav zoo kuj tseem xav tau thaum lub sijhawm ua haujlwm kom txo tau qhov kub thiab txias thiab txhim kho qhov zoo ntawm kev ua haujlwm.
(III) Daim ntawv thov teb
Cast steel bearing seats ua lub luag haujlwm tseem ceeb hauv ntau qhov siab -kawg thiab tseem ceeb teb nrog lawv cov kev ua tau zoo heev. Hauv kev lag luam cov cuab yeej loj, xws li cov tshuab hluav taws xob tawg thiab cov hloov pauv hauv kev lag luam metallurgical (xws li bearings UCP207ZG, UCF209-28ZG), cov cuab yeej no loj loj thiab muaj cov khoom hnyav thaum ua haujlwm. Cam khwb cia hlau bearing rooj tuaj yeem txhawb nqa bearings nrog lub zog siab thiab siab tawv kom ntseeg tau ntev - lub sijhawm thiab siab - thauj khoom ntawm cov khoom siv. Hauv kev ua haujlwm siab- nrawm nrawm, xws li qee qhov ntawm cov tshuab dav hlau, kev khiav ceev ceev heev thiab qhov yuav tsum tau muaj rau cov rooj zaum muaj siab heev. Cam khwb cia hlau bearing rooj tuaj yeem tiv taus lub zog loj centrifugal thiab cuam tshuam lub zog coj los ntawm kev sib hloov ceev kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov tshuab. Hauv cov tshuab mining loj, xws li crushers thiab pob zeb (xws li UCF206, UCFL208), qhov chaw ua haujlwm hnyav. Lawv yuav tsum tsis tsuas yog dais hnyav, tab sis kuj cuam tshuam nrog kev cuam tshuam ntawm ore. Qhov kev ua tau zoo ntawm cov cam khwb cia steel bearing rooj ua rau lawv tsuas yog xaiv thiab muab kev txhawb nqa zoo rau kev ua haujlwm tsuas.
Hauv cov ntsiab lus: cam khwb cia hlau bearing rooj yog tsawg- tus nqi thiab muaj kev hnav zoo ntawm qhov ceev thiab lub teeb, tab sis lawv cov tawv tsis zoo; cam khwb cia steel bearing lub rooj muaj siab - lub zog thiab tawv, thiab tuaj yeem hloov mus rau kev kub ceev thiab hnyav, tab sis lawv cov nqi thiab kev ua haujlwm nyuaj kuj siab dua. Thaum txiav txim siab tiag tiag, peb tsis tuaj yeem hais tias cov hlau cam khwb cia hlau lossis cov hlau cam khwb cia zoo dua, tab sis peb yuav tsum ua tib zoo xav txog ntau yam xws li kev ua haujlwm ntawm cov cuab yeej siv, pob nyiaj siv, thiab kev ua haujlwm.
