U-bolts tuaj yeem pom hauv ntau lub tsheb lag luam, suav nrog cov tsheb thauj mus los. Lawv yog siv los ua kom ruaj khov rau ntau qhov chaw ntawm lub tsheb, xws li nplooj springs, ncua kev kaw lus, thiab tso pa tawm, thiab lwm yam. Xaiv qhov tsim nyog U-bolts yog qhov tseem ceeb los xyuas kom meej lub neej ntev thiab kev nyab xeeb ntawm lub tsheb npav. Tsab ntawv xov xwm no yuav muab cov lus qhia txog yuav ua li cas xaiv qhov tsim nyog thiab zoo U-bolts rau tsheb npav.
Hom U-bolts:
U-bolts tuaj ntawm ntau hom thiab ntau thiab tsawg, txhua tus muaj lub hom phiaj sib txawv. Feem ntau, U-bolts raug cais raws li lawv cov duab, qhov loj me, thiab daim ntawv thov. Hauv qab no yog qee qhov feem ntau siv U-bolts thiab lawv cov ntawv thov.
1. Round Khoov U-bolts:
Round khoov U-bolts yog hom U-bolts feem ntau siv hauv kev lag luam tsheb. Lawv yog cov puag ncig hauv cov duab thiab muaj threaded kawg ntawm txhua ceg. Cov threaded xaus yog txuas nrog lub txiv ntseej thiab lub tshuab ntxhua khaub ncaws, tuav cov nplooj springs thiab lwm yam kev ncua rau lub qag. Round khoov U-bolts muaj nyob rau hauv ntau qhov sib txawv thiab cov ntaub ntawv, nyob ntawm seb lub tsheb tsim thiab qauv.
2. Square Khoov U-bolts:
Square khoov U-bolts muaj squared-tawm cov ces kaum, ua rau lawv muaj zog dua piv rau lawv puag ncig khoov counterparts. Lawv kev tsim kho tso cai rau lawv muab kev txhawb nqa ntxiv, ua rau lawv zoo tagnrho rau cov tsheb hnyav xws li tsheb thauj khoom thiab tsheb npav. Square khoov U-bolts feem ntau yog ua los ntawm cov hlau lossis hlau, vim lawv yuav tsum tau tiv taus cov khoom hnyav.
3. Semi-Round U-bolts:
Semi-round U-bolts yog kev sib xyaw ua ke ntawm puag ncig thiab square khoov U-bolts. Lawv qhov kawg yog puag ncig, thaum lawv ob sab muaj lub tiaj tiaj, ua rau lawv xaiv zoo rau cov ntawv thov uas yuav tsum tau muaj zog ntxiv thiab kav ntev.
Thawj qhov yuav tsum tau xav txog thaum xaiv U-bolts rau cov tsheb thauj mus los yog qhov loj thiab ntev ntawm cov bolts. Qhov loj thiab ntev yuav nyob ntawm qhov kev thov tshwj xeeb thiab cov khoom raug ruaj ntseg. Raws li txoj cai dav dav, koj xav tau U-bolt uas ntev me ntsis tshaj qhov kev ncua deb ntawm cov xov ntawm lub bolt. Qhov no yog los xyuas kom meej tias muaj xov txaus los zawm lub bolt kom zoo.
Txhawm rau txiav txim siab qhov loj thiab ntev ntawm U-bolt, ntsuas qhov kev ncua deb ntawm ob lub ntsiab lus ntawm lub tsheb uas U-bolt yuav ruaj ntseg. Qhov no tuaj yeem yog qhov kev ncua deb ntawm ob daim hlau ntawm lub caij nplooj ntoo hlav lossis qhov kev ncua deb ntawm tus ntoo khaub lig-tus tswv cuab ntawm lub tsheb ncej. Tsis tas li ntawd, xav txog qhov tuab ntawm cov khoom raug ruaj ntseg. U-bolt yuav tsum muaj cov xov txaus kom haum kom ruaj ntseg, tab sis tsis txhob ntau dhau uas nws lo tawm ntau dhau.
Xaiv cov khoom raug
U-bolts tuaj yeem tsim siv cov khoom sib txawv, suav nrog hlau, stainless hlau, thiab txhuas. Kev xaiv ntawm cov khoom siv yuav nyob ntawm qhov kev thov thiab ib puag ncig. Hlau yog cov khoom siv feem ntau siv hauv U-bolts vim nws cov kav ntev thiab lub zog. Nws yog haum rau feem ntau cov ntawv thov thiab tuaj yeem tiv taus cov xwm txheej hnyav. Txawm li cas los xij, thaum siv nyob rau hauv ib puag ncig uas muaj dej noo thiab ntsev, cov hlau yuav corrode dhau sijhawm.
Stainless hlau yog cov khoom siv tiv thaiv corrosion uas tsim nyog rau kev siv nyob rau hauv ib puag ncig uas muaj qhov ua tau zoo ntawm corrosion. Nws yog kim dua hlau thiab feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau muaj kev tiv thaiv corrosion. Aluminium yog cov khoom siv hnyav uas siv qhov kev txo qhov hnyav yog qhov tseem ceeb, xws li hauv cov tsheb thauj khoom hnyav. Nws tsis muaj zog npaum li cov hlau thiab tuaj yeem deform thaum raug hnyav.
Xav txog hom xov
Cov xov hom U-bolts tuaj yeem sib txawv, thiab nws yog qhov tseem ceeb uas yuav tsum xaiv hom raug rau daim ntawv thov tshwj xeeb. Cov xov ntau tshaj plaws yog cov xov ntxhib thiab cov xov zoo. Coarse threads raug pom zoo rau fastening high-stress qhov chaw uas yuav tsum muaj siab clamping quab yuam, xws li cov khoom ncua kev kawm ntawv. Cov xov zoo, ntawm qhov tod tes, yog siv rau cov ntawv siv sib dua uas xav tau kev nruj dua.
Qhov ntev ntawm cov xov kuj tseem ua lub luag haujlwm tseem ceeb hauv lub zog clamping ntawm U-bolt. Ntev threads muab ntau dua clamping quab yuam vim lawv muaj peev xwm mus sib sib zog nqus mus rau hauv lub qhov chaw yog ruaj ntseg. Txawm li cas los xij, cov xov ntev ntev yuav tsis haum rau cov ntawv thov uas qhov chaw txwv.
Xyuas kom muaj txheej txheej zoo
Txheej yog qhov tseem ceeb hauv kev tiv thaiv U-bolts los ntawm corrosion thiab ncua lawv lub neej kev pab cuam. Ntau hom txheej txheej tuaj yeem siv rau U-bolts los txhim kho lawv cov kev tiv thaiv corrosion. Cov txheej txheem feem ntau siv hauv U-bolts yog dub oxide, zinc plating, thiab kub-dip galvanizing.
Dub oxide txheej muab cov xim dub tiav rau U-bolt thiab siv los txhim kho nws cov tsos thiab muab lub hauv paus rau xim yog tias xav tau. Zinc plating suav nrog kev ntxig U-bolt rau hauv da dej ntawm zinc molten los tsim cov txheej tiv thaiv zinc ntawm qhov ntsia hlau. Cov txheej no yog tsim rau cov ntawv thov uas tsis muaj corrosion kuj. Kub-dip galvanizing yuav immersing lub U-bolt nyob rau hauv molten zinc, uas ua rau ib tug tuab txheej ntawm zinc txheej uas muab zoo corrosion kuj. Cov txheej txheej no yog tsim rau cov ntawv thov raug rau qhov chaw hnyav, xws li cov chaw hauv dej hiav txwv.
Txheeb xyuas Cov Qauv Ua Raws Cai
Thaum muas U-bolts rau cov tsheb npav, nws yog ib qho tseem ceeb kom paub tseeb tias lawv ua tau raws li cov qauv tshwj xeeb. Cov qauv siv los xyuas kom meej tias U-bolts yog qhov zoo thiab tsim nyog rau lawv daim ntawv thov. Cov qauv siv feem ntau siv hauv Asmeskas rau U-bolts yog SAE J429 tus qauv, uas qhia txog cov khoom siv thiab cov khoom siv ntawm U-bolts.
Lwm tus qauv siv hauv Tebchaws Europe yog DIN lossis EN cov qauv rau U-bolts. Cov qauv no qhia txog qhov ntev, cov khoom siv, thiab cov khoom siv kho tshuab ntawm U-bolts siv nyob rau hauv ntau daim ntawv thov. Kev ua raws li cov qauv ua kom ntseeg tau tias U-bolts ua tau raws li qhov xav tau tshwj xeeb thiab muaj txiaj ntsig zoo.
Los ntawm kev xaiv txoj cai U-bolt, tuaj yeem ua kom ntseeg tau tias lub tsheb ncua kev ua haujlwm ua haujlwm zoo thiab nyab xeeb.
