Slewing bearing qauv tooj tsis yog random assortments ntawm cov ntawv thiab cov lej; lawv ua tib zoo tsim cov lej uas qhia cov ntaub ntawv tseem ceeb ntawm cov kabmob cov lus qhia tshwj xeeb. Tus qauv naj npawb yuav zoo li "010.40.1000" thiab tuaj yeem tawg ua ob peb yam tseem ceeb, txhua tus muab cov ntsiab lus tshwj xeeb txog cov kabmob.
1. Ua ntej
Cov ntawv ua ntej, yog tias tam sim no, feem ntau qhia txog cov yam ntxwv tshwj xeeb lossis kev hloov kho rau tus qauv tsim. Common prefixes muaj xws li:
K: Qhia txog cov kabmob nrog lub iav ntawm lub nplhaib sab hauv lossis sab nraud.
H: Sawv cev rau cov kabmob nrog los ntawm qhov.
Z: Qhia txog cov kabmob uas muaj ntaub thaiv npog.
2. Series lossis Hom Code
Thawj txheej ntawm tus lej feem ntau sawv cev rau cov koob lossis hom ntawm cov kabmob slewing. Common series muaj xws li:
010: Ib kab kab slewing bearing.
011: Cross-roller slewing bearing.
012: Peb-kab cov menyuam slewing bearing.
Cov lis dej num no pab cov neeg siv ceev nrooj txheeb xyuas qhov tsim qauv yooj yim thiab lub peev xwm thauj khoom ntawm cov kabmob.
3. Loj thiab Dimension Codes
Ua raws li cov lej cim, cov lej tom ntej feem ntau qhia txog cov kabmob qhov ntev. Piv txwv li, hauv tus qauv naj npawb "010.40.1000":
40: Hais txog txoj kab uas hla los yog qhov loj me uas pab kom paub qhov sib txawv ntawm qhov sib txawv hauv tib lub koob.
1000: Sawv cev txoj kab uas hla hauv millimeters.
Kev nkag siab txog cov lej no yog qhov tseem ceeb rau kev ua kom cov kabmob haum zoo kawg nkaus hauv nws qhov chaw thov.
4. Suffix
Lub ntsiab lus, tshwm nyob rau hauv qhov kawg ntawm tus qauv tooj, muab cov ntaub ntawv ntxiv txog cov kabmob cov yam ntxwv:
2Z: Qhia tias ob tog muaj cov ntaub thaiv npog.
2 RS: Qhia txog cov roj hmab foob ntawm ob sab.
T: Sawv cev ib tug tapered bore.
Cov lus kawg no pab kho cov kabmob rau cov kev xav tau tshwj xeeb, txhim kho kev ua haujlwm thiab kev ua haujlwm ntev.
Common Slewing Bearing Hom thiab lawv daim ntawv thov
1. Ib-kab Pob Slewing Bearings
Tsim los ntawm cov lej code "010", cov kabmob no yog tus cwj pwm los ntawm lawv txoj kev yooj yim thiab kev ua haujlwm zoo hauv kev tuav cov khoom nruab nrab. Lawv feem ntau yog siv rau hauv lub teeb rau nruab nrab daim ntaub ntawv xws li me me cranes, aerial work platforms, thiab hnub ci trackers. Cov kev teeb tsa ib leeg tso cai rau kev sib hloov kom zoo thaum tuav cov qauv tsim.
2. Hla-Roller Slewing Bearings
Coded raws li "011", cov bearings siv cylindrical rollers teem nyob rau hauv ib tug ntoo khaub lig qauv, muab enhanced load peev xwm thiab rigidity. Cov ntawv thov uas xav tau siab precision thiab ruaj khov, xws li robotics, kho mob scanners, thiab indexing tables, tau txais txiaj ntsig zoo los ntawm kev tsim tus ntoo khaub lig. Lub peev xwm los tuav ob qho tib si radial thiab axial loads ua rau lawv muaj ntau yam thiab tseem ceeb hauv qhov xav tau ib puag ncig.
3. Peb-Law Cov Menyuam Slewing Bearings
Cuam tshuam los ntawm series code "012", cov bearings no yog engineered rau hnyav-duty daim ntaub ntawv qhov twg siab tshaj load peev xwm yuav tsum tau. Lawv muaj peb kab sib cais ntawm cov menyuam yaus-ib qho rau radial loads thiab ob rau axial loads-tso cai rau lawv los txhawb qhov hnyav thiab kev ntxhov siab. Kev lag luam xws li cua zog, tshuab hnyav, thiab cov khoom siv chaw nres nkoj feem ntau siv peb-kab cov menyuam slewing bearings.
Cov yam ntxwv cuam tshuam rau Slewing Bearing xaiv
1. Lub peev xwm thauj khoom
Nkag siab txog cov kev xav tau ntawm kev thov yog qhov tseem ceeb thaum xaiv cov kabmob slewing. Tus qauv naj npawb series thiab dimension codes pab txiav txim siab lub peev xwm los lis axial, radial, thiab lub caij loads. Rau cov ntawv thov uas muaj cov khoom tseem ceeb, xws li kev tsim kho cranes lossis cua turbines, xaiv cov kabmob nrog cov qauv tsim muaj zog, zoo li hom peb-kab cov menyuam, yog qhov tseem ceeb.
2. Kev ua haujlwm ib puag ncig
Ib puag ncig uas cov kabmob ua haujlwm cuam tshuam nws qhov kev ua tau zoo thiab
kev nyob ntev. Cov ntawv thov nyob rau hauv cov xwm txheej hnyav, xws li offshore drilling platforms lossis cov tshuab ua haujlwm hnyav, xav tau cov bearings nrog superior sealing thiab tiv thaiv nta. Cov lus xaus nyob rau hauv tus qauv naj npawb, xws li "2RS" lossis "2Z," qhia tias muaj cov roj hmab ntsaws ruaj ruaj los yog cov ntaub thaiv npog tiv thaiv, feem, uas txhim kho cov kabmob tiv thaiv kom tsis txhob muaj kab mob thiab ya raws.
3. Ceev thiab Precision
Hauv cov ntawv thov uas muaj kev sib hloov ceev thiab kev txav ceev yog qhov tseem ceeb, xws li hauv CNC machinery lossis robotic caj npab, hom dov cov ntsiab lus thiab lawv cov kev npaj ua lub luag haujlwm tseem ceeb. Ib leeg-kab pob slewing bearings, piv txwv li, muab qhov sib npaug ntawm qhov nrawm thiab qhov tseeb vim lawv qhov kev sib hloov qis dua piv rau cov qauv tsim. Conversely, cross-roller slewing bearings, nrog rau lawv cov load muaj peev xwm thiab stability, yog zoo tagnrho rau high-precision daim ntaub ntawv uas yuav tsum tau ob qho tib si ceev thiab rigidity.
4. Kev txhim kho thiab tu
Qhov yooj yim ntawm kev teeb tsa thiab kev saib xyuas yog lwm qhov kev txiav txim siab thaum xaiv slewing bearings. Cov nta xws li tapered bores (qhia los ntawm cov lus "T") ua kom yooj yim rau kev sib dhos thiab kev teeb tsa, txo qhov kev pheej hmoo ntawm misalignment thiab hnav ntxov ntxov. Tsis tas li ntawd, cov bearings nrog lub zog ua ke (qhia los ntawm lub npe "K") tuaj yeem txhim kho cov txheej txheem kev sib koom ua ke hauv cov ntawv thov uas xav tau ob qho tib si kev sib hloov thiab lub zog xa mus.
