Yuav ua li cas xaiv cov neeg ntxhua khaub ncaws dawb rau kev ua haujlwm sib txawv?
Ntau tus neeg tsim tawm lossis cov neeg ua haujlwm ua haujlwm feem ntau fim qhov teeb meem no thaum xaivCov Xyooj kov cov kabmob: "Vim li cas qee cov tshuab ntxhua khaub ncaws xeb sai sai sai, thaum lwm tus deform sai sai hauv cov khoom hnyav?" Qee qhov kev xav tias "Tus kws kho hlau ib qho twg yuav ua," kev xav tau ntawm cov kev ua haujlwm tshwj xeeb rau cov khoom siv, qauv, thiab meej. Lwm tus dig muag los cuag "lub zog siab," hloov chaw ntawm cov hlau hlau tsis muaj tseeb rau cov roj carbon hlau txawv, tsis tsim nyog nce nqi. Nyob rau hauv kev muaj tiag, lub ntsiab cai tseem ceeb ntawm cov kabmob cov kabmob xaiv yog "Daim ntawv thov kev yoog raws ib puag ncig, kev kho kom haum rau hauv} nyob rau hauv high - ceev tshuab TUAM cov ntawv thov, Precision thiab coj kev tsis kam yog legamount yog qhov tseem ceeb; Nyob rau hauv hnyav - load crane cov ntawv thov, txhim kho nruj thiab deformation tiv taus yog qhov tseem ceeb. Niaj hnub no, peb systematically tsoo cov xaiv log rauCov Xyooj kov cov kabmobHla kev ua haujlwm sib txawv - los ntawm kev txiav txim siab ntxuav kom yog thiab tsis txhob siv cov khoom lag luam tsis ua haujlwm.
Ua ntej, hais meej: 3 yam tseem ceeb ntev rau cov kabmob tshuab xaiv
Txhawm rau xaiv cov uas muaj royer txoj cai, thawj zaug pinpoT peb qhov chaw nyob ntev raws li "cov cai ua haujlwm." Cov ntawv no lub hauv paus tseem ceeb rau xaiv, nrog txhua qhov loj me qhia txog kev ntxuav tes ua haujlwm ruaj khov:
Cov Khoom Siv Qhov Loj:Txiav txim siab cov washer qhov kub tiv thaiv, corrosion tsis kam, thiab lub zog - Lub hauv paus rau kev ua haujlwm.
Precision Qhov loj:Cuam tshuam axial txav thiab quab yuam faib cov kev faib tawm hauv cov kabmob. Precision cov khoom yuav tsum nruj tswj hwm ntawm cov tiaj tiaj thiab parallelism.
Txheej txheem Dimension:Adapts rau kev sib hloov chaw thiab cov qauv thauj khoom. Piv txwv li, ultra {- qhov chaw yuav tsum tau nyias {2} cov neeg cuam tshuam thauj khoom siv ntxhua khaub ncaws nrog cov qauv cushioning.
Ob, cov kabmob uas muaj tshuab ntxhua khaub ncaws xaiv cov schemes rau kev ua haujlwm sib txawv
Cov yuav tsum tau sib txawv sib txawv heev hla kev ua haujlwm sib txawv, qhov tsim nyog xaiv cov khoom siv, qauv, thiab qauv. Hauv qab no yog cov lus qhia piav qhia ntxaws ntxaws rau 6 kev ua haujlwm raug ua haujlwm, suav nrog ntau cov qauv tsis sib xws thiab txuam piv cov piv txwv:
1. Kev mob 1: Qhov chaw qhuav huv ib puag ncig ntawm qhov kub me me {{2} tus nqi- Qhov ua tau zoo
Cov yuav tsum tau:Yooj yim load - bearing} cov kabmob, kev hnav qis, tsis muaj nqi tshwj xeeb;
Kev Xaiv Kev Xaiv:
Khoom siv:Cov qauv hlau, tensile lub zog ntau dua lossis sib npaug nrog 400MPA, Hardness HB150-180, tus nqi qis} rmb / thooj);
Precision:Cov qauv raug yog, tiaj tus neeg tsawg dua lossis sib npaug rau 0.05mm, kev sib npaug rau 0.08mm / m, ntsib cov khoom siv Axial (tsawg dua los yog sib npaug rau 0.1mm);
Tus qauv:Txheem tiaj tus ntxhua khaub ncaws, thickness 1 - 3mm. Sab hauv lub cheeb ua cov kabmob ncos txoj kab uas hla los ntawm 0.5-1mm (kom tiv thaiv kev sib txhuam). Txheej txheej hla dhau ntawm cov xeeb ntxwv kawg lub ntsej muag los ntawm 2-5mm (los xyuas kom meej load-bears).
Daim Ntawv Thov Piv Txwv:Cov kabmob cov kab ke rau kev siv sab hauv tsev sab hauv tsev nrog axial quab yuam kwv yees {{kn. Xaiv Q235 Cov Pa Roj Carbon Washer (2 hli tuab, ID φ20mm, Od φ30mm). Kev pabcuam lub neej ntev txog li 3-5 xyoos, nqi tsuas yog 1.2 yuan / thooj.
Cov kev ceev faj:Tsis tsim nyog rau cov av noo lossis plua plav ib puag ncig vim muaj kev ua kom muaj xeb. Yuav tsum muaj kev tiv thaiv cov av yooj yim.
2. Kev ua haujlwm 2: Siab -} huab cua sov ib puag ncig {}} pa hluav taws ua ntej
Cov yuav tsum tau:Kub tiv taus ntau dua los yog sib npaug rau 150 degree, tsis muaj muag muag lossis deformation lossis deformation ntawm cov kub thiab meej;
Xaiv Xaiv:
Cov khoom siv: xaiv raws li kev faib tawm qhov kub:
Precision:Lub siab precision, thermal deformation tsawg dua los yog sib npaug rau 0.01mm / m ntawm qhov kub;
Tus qauv:Txuas nrog cua sov dissipation qhov rau txhim kho cua txias, lossis cov tshuab ntxhua khaub ncaws;
Daim Ntawv Thov Piv Txwv:Lub taub dej twj tso cov kabmob hauv cov cav hauv tsheb (kwv yees li . 200 degree). Xaiv GH3030 siab - kub alloy alloy wasy washer (2mm tuab, id φ25mm, Od φ35mm). Siab - kub deformation tsawg dua los yog sib npaug rau 0.005mm, bearing lifespan txog 2-3 xyoos;
Ntsiab lus hais tias:Tsom rau cov khoom siv "siab - kub tawm lub zog" los tiv thaiv cov khoom siv yas ntawm cov chaw kub.
3. Kev ua haujlwm 3: Hnyav Load / Kev Cuam Tshuam Ib Cheeb Tsam - lub zog tseem ceeb
Cov yuav tsum tau:Dag taus axial quab yuam ntau dua los yog sib npaug rau 10kn, tiv thaiv tsawg dua lossis sib npaug ntawm 1.5 rated tus nqi), hardness ntau dua los yog sib npaug rau HB200;
Kev Xaiv Kev Xaiv:
Cov Khoom Siv: High - Lub zog bearon lossis quemed thiab tempered 45 steel, hardness hrc28-32):
Nruab nrab - hnyav load (axial quab yuam 10-30kn):Quenched thiab tempered 45 steel txuas, tensile lub zog ntau dua los yog sib npaug rau 800MPA, nqi} rmb / thooj;
Heavy load (axial force >30kn):SUJ2 Cov Kabmob Hlau Txuas, Tensile lub zog ntau dua los yog sib luag rau 1000mpa, Hardness HRC58-62, tus nqi} rmb / thooj;
Cuam tshuam Load:Hardened alloy warmers, cuam tshuam kev sib raug zoo dua lossis sib npaug rau 20j / cm², tiv thaiv kev cuam tshuam los;
Precision:Precision Qhov tseeb (Flatness tsawg dua los yog sib npaug rau 0.02mm) kom ntseeg tau tias muaj kev ntxhov siab hauv zos (sib npaug rau 60% ntawm cov khoom xa tawm lub zog);
Tus qauv:Tuab tshuab ntxhua khaub ncaws (tuab ntau dua los yog sib npaug rau 3 hli kom nce load - bearing rears los tiv thaiv kev ntxhov siab;
Lub Zog Muab Xam:Xam cov washer lub load -} bearing thaj tsam ua ntej xaiv tsawg dua los yog sib npaug ntawm cov siab ntawm cov khoom.
Qhov thib peb, peb cov kauj ruam tseem ceeb rau cov kabmob sib xaiv
Thaum ntsib kev ua haujlwm nyuaj, ua raws li peb {{0} → cov txheej txheem sib piv → kev sib piv "kom ntseeg tau tseeb:

Plaub, Cov Ntsiab Lus: Cov Lus Cim Tseem Ceeb thiab Tus Nqi ntawm Cov kabmob Kev Xaiv
Lub ntsiab lus ntawm cov kabmob ntawm cov bearer xaiv nyob rau hauv "precisely txuam kev cai ua haujlwm nrog cov yam ntxwv washer." Cov tub ntxhais tseem ceeb tuaj yeem ua kom tiav li "peb {{-} qhov chaw sib koom tes thiab plaub- Ruam siv":Siv "cov khoom siv, precision, thiab cov qauv" raws li peb txoj kev txiav txim siab ntawm "kev txiav txim siab los ntawm kev ua haujlwm"
Hais txog cov xwm txheej yoog, ib puag ncig txuj ci yuav tsum muaj nqi nrog kev ua tau zoo {}} fits - txhua txoj hauv kev. Kev siv cov pa roj carbon steel ua rau muaj kev ua tsis tiav, thaum deploying cov tshuaj ntxuav tej hub ntawm cov khoom siv cov khoom siv kom ceev. Tsuas yog "xav tau {-} Raws li kev xaiv" ua tiav qhov kev ua tau zoo {}} tus nqi sib npaug.
Tus nqi ntawm kev xaiv kom tsim nyog txuas ntxiv ntawm kev tiv thaiv lub tshuab ntxhua khaub ncaws ua ntej ua tsis tiav. Nws tseem ceeb txuas cov kabmob lub zog system (los ntawm 30%-}}}}}}}}}}}}}}} Txawm hais tias koj yog tus tsim qauv lossis ua haujlwm ua haujlwm, nyob rau "kev sib txuam tshwj xeeb" yog tus yuam sij rau xaiv txoj caiCov Xyooj kov cov kabmob, tso ib lub hauv paus ruaj khov rau cov khoom siv ruaj khov.
