Kev lag luam bearings: hom, kev taw qhia kev xaiv thiab chaw siv
Industrial bearings yog ib qho tseem ceeb ntawm cov khoom siv kho tshuab. Lawv ua kom muaj kev ua haujlwm zoo thiab ruaj khov ntawm cov cuab yeej los ntawm kev txo cov kev sib txhuam thiab txhawb kev sib hloov. Txawm hais tias nws yog lub tsheb, cua turbine, lossis lub Hoobkas cov kab ntau lawm, bearings ua lub luag haujlwm tseem ceeb. Kab lus no yuav tshawb txog cov hom kev lag luam, yuav ua li cas xaiv cov bearings zoo, xaiv cov kev txiav txim siab thiab lawv daim ntawv thov dav los pab koj nkag siab zoo txog cov ntsiab lus tseem ceeb no.
1. Dab tsi yogindustrial bearings?
Cov kabmob muaj cov kabmob yog cov khoom siv tshwj xeeb uas feem ntau yog siv los txhawb kev sib hloov lub cev (xws li cov ncej, lub zog lossis lub log), txo kev sib txhuam thaum lub sijhawm txav, thiab tiv taus radial lossis axial loads los ntawm cov khoom siv. Nws cov haujlwm tseem ceeb yog los xyuas kom meej qhov smoothness, precision thiab lub neej ntev ntawm kev siv tshuab.
2. Cov hom tseem ceeb ntawm kev lag luam bearings
Raws li cov qauv thiab txoj hauv kev ua haujlwm, cov bearings muaj peev xwm muab faib ua pawg hauv qab no:
- Rolling bearings
Sib sib zog nqus groove pob bearings: ntau hom, haum rau nruab nrab thiab qis speeds, radial thiab lub teeb axial loads, xws li motors thiab khoom siv hauv tsev.
Angular contact pob bearings: tuaj yeem tiv taus radial thiab axial loads tib lub sijhawm, feem ntau siv hauv tshuab cuab yeej spindles, twj, thiab lwm yam.
Tapered roller bearings: Tsim los tiv thaiv hnyav radial thiab axial loads, feem ntau yog siv rau hauv tsheb log thiab gearboxes.
Cylindrical roller bearings: High radial load peev, haum rau cov tshuab hnyav (xws li cua turbines).
- Sliding bearings (dav hlau bearings)
Ua hauj lwm los ntawm kev sib txhuam zawv zawg, tsis tas yuav tsum muaj cov ntsiab lus dov, thiab feem ntau yog siv rau hauv cov xwm txheej qis, siab load (xws li turbines, nkoj propulsion systems).
- Thrust bearings
Tshwj xeeb tsim los tiv thaiv axial loads, xws li helical iav txhawb nyob rau hauv gearboxes.
- Tshwj xeeb ua hauj lwm mob bearings
Ceramic bearings: Kub thiab corrosion kuj, haum rau huab cua puag ncig (xws li aerospace, chemical khoom).
Self-lubricating bearings: Tsis tas yuav tsum tau lubrication sab nraud, siv nyob rau hauv kev kho mob nyuaj (xws li cov khoom noj khoom haus, khoom siv kho mob).
3. Yuav ua li cas xaiv txoj cai muaj kabmob?
Cov laj thawj hauv qab no yuav tsum tau txiav txim siab ua tiav txhawm rau xaiv txoj kev coj tus kheej:
1. Load hom thiab loj
Radial load: quab yuam perpendicular mus rau lub axis (xws li rub ntawm lub pulley).
Axial load: Force parallel rau lub axis (xws li thrust thaum lub zog mesh).
Mixed load: Angular contact bearings los yog tapered roller bearings yuav tsum tau.
2. Kev ceev ceev
Sib sib zog nqus groove pob bearingslos yog ceramic bearings yog nyiam rau kev siv ceev ceev (xws li hluav taws xob spindles).
Cylindrical cov menyuam bearingsyog tsim nyog rau qhov tsawg ceev thiab hnyav load scenarios (xws li cranes).
3. Ib puag ncig ua haujlwm
Kub: Thaum tshav kub kub-resistant steel los yog ceramic bearings yuav tsum tau rau qhov kub thiab txias ib puag ncig; antifreeze roj yuav tsum tau rau qhov kub thiab txias ib puag ncig.
Corrosiveness: Stainless hlau lossis coated bearings tuaj yeem xaiv rau cov khoom siv tshuaj.
Sealing yuav tsum tau: bearings nrog plua plav npog los yog sealing rings yuav tsum tau rau cov plua plav los yog av ntub.
4. Kev txhim kho thiab tu
Nws puas yooj yim rau nruab? Split bearings tuaj yeem ua kom yooj yim txij nkawm.
Puas yuav tsum tau ua lubrication ntau zaus? Self-lubricating bearings tuaj yeem txo cov nqi kho.
IV. Kev xaiv xaiv
Tsis txhob "hloov dhau": xaiv raws li kev ua haujlwm tiag tiag, yam tsis muaj qhov muag tsis pom kev ua haujlwm siab.
Xav txog tag nrho cov nqi: cov nqi qis qis yuav muaj lub neej luv luv, ua rau muaj kev hloov pauv ntau dua thiab cov nqi tu.
Tus neeg muab kev pabcuam kev pabcuam: Xaiv lub npe txhim khu kev qha uas tuaj yeem muab cov txheej txheem thiab cov lus qhia kev teeb tsa (xws li SKF, NSK, TIMKEN). TP tuaj yeem muab kev cai bearings rau koj.
Kev txheeb xyuas kev sib raug zoo: Xyuas kom tseeb tias cov kabmob loj sib npaug ntawm cov khoom siv thiab cov vaj tsev.
V. Tej thaj chaw thov kev lag luam bearings
Automotive kev lag luam: log hub bearings, gearbox bearings,cav Cheebtsam.
Kev lag luam hluav taws xob: cua turbine lub ntsiab ncej bearings, hydraulic turbine txhawb nqa bearings.
Kev lag luam kev lag luam: tshuab cuab yeej spindles, muaj neeg hlau sib koom tes bearings.
Aerospace: kub resistant cav bearings, tsaws iav bearings.
Cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob: lub cev muaj zog bearings, hard disk drive spindle bearings.
Txawm tiasindustrial bearingsme me, lawv yog "tus saib xyuas tsis pom" ntawm kev ua haujlwm zoo ntawm cov tshuab niaj hnub. Kev xaiv cov kabmob kom raug thiab tsim nyog rau kev ua haujlwm tsis zoo tuaj yeem txhim kho cov cuab yeej ua haujlwm tau zoo, tab sis kuj tseem txuas ntxiv kev pabcuam lub neej thiab txo cov nqi ua haujlwm thiab kev saib xyuas. Nws raug nquahu kom ua haujlwm nrogcov kws tshaj lijthaum xaiv cov qauv thiab txiav txim siab zoo tshaj plaws raws li cov kev thov tshwj xeeb.
Yog tias koj xav paub ntau ntxiv txog kev xaiv cov kabmob lossis tau txais phau ntawv qhia khoom, thovtiv taujpeb pab neeg technical!
