Yuav ua li cas xaiv cov kabmob rau cov hlau caster hlau?

Xaiv cov coj txoj cai rau cov xov tooj hlau hlau yuav tsum muaj kev xav txog lub tawb nqa khoom, noo noo, thiab roj nrawm, thiab kev kho kom tau. Lub hom phiaj tseem ceeb yog kom ntseeg tau tias cov kabmob lub load - Cov kabmob muaj peev xwm, thiab cov khoom lag luam tawm ntawm lub zog hlau lub zog. Cov hauv qab no yog cov lus qhia kom ntxaws xaiv thiab kev tsom xam ntawm qhov zoo thiab qhov tsis zoo ntawm ntau hom hom:

I. Cov txheej txheem tseem ceeb rau kev xaiv cov kabmob hlau dua
1. Thauj lub zog: txuam nrog hnyav {{1} }ostoom peev txheej ntawm hlau casters
Cov ntsiab lus zoo ntawm hlau casters yog lawv cov khoom siab siab - cov kabmob muaj nuj nqi (feem ntau ntau dua lossis sib npaug rau 500kg ib lub log). Bearings yuav tsum tau ua raws li lub zog ruaj khov ntawm ntau dua los yog sib npaug rau 1.2 zaug lub xov tooj lub tawb (tso cai rau ib qho kev nyab xeeb). Cov kabmob hom sib txawv tseem ceeb ntawm lub teeb thiab hnyav load scenarios:
Rau qhov tsawg rau nruab nrab loads (500-1000kg): Pob bearings yog ib qho kev xaiv;
Rau cov khoom siv hnyav (1000-3000KG): Koob rau cov menyuam kabmob lossis cov menyuam nqa khoom tau zoo dua;
For extremely heavy loads (>3000kg): Custom double-row roller bearings or self-aligning bearings are required.

2. Ib puag ncig kev yoog raws: tiv taus hmoov av, ya raws, thiab corrosion
Hlau hlau nplaum feem ntau siv hauv cov chaw ua haujlwm nyuaj xws li cov chaw cob qhia thiab cov chaw tsim khoom, yog li cov kabmob yuav tsum tiv taus rau kev nkag mus.

Cov plua av / Gravel ib puag ncig (ZZ) lossis cov ntsaws ruaj ruaj (2rs) los tiv thaiv cov kabmob RAGONS thiab hnav cov kabmob Radifays.

Cov ntub dej ntub dej / tsim cov roj nplaum: Xaiv cov khoom siv stainless hlau los yog galvanized bearings nrog nitrile roj hmab ntsaws ruaj ruaj

High-temperature environments (>100 Qib Kawm Ntawv): Xaiv cov siab kub- kub bearing steel (xws li suj2) thiab siab} roj tov (xws li polyurea) los tiv thaiv kom txhob muaj roj ntsha.

3. Ceev thiab Smoothness: Ntsuas Kev Tawm thiab Lifespan
Hlau hlau casters feem ntau ua haujlwm ntawm kev nrawm nrawm (tsawg dua lossis sib npaug nrog 5 km / h), tab sis cov khoom hnav ib ce yuav tsum zam.

Tsawg - ceev, hnyav {{{{1} {lut rad ib puag ncig: Xav tau cov menyuam yaus cov menyuam yaus thiab kev cuam tshuam tsis kam).

Txog kev nquag kauj: Xaiv cov pob kabmob nrog tawb (qis dua kev tiv thaiv thiab kho tus nqi kho mob:}} kev txij nkawm- dawb lossis lubricated bearings raws li koj cov kev xav tau.
Rau cov ntawv thov tsis tu ncua yog qhov tsis yooj yim (xws li cov khoom siv sab nraum zoov): Xaiv ua ntej lub taub hau, kom ua haujlwm ntev ntev {} kev ua haujlwm} kev ua haujlwm pub dawb).
Rau siab - cov khoom siv muaj lubricated (nrog pre {1} - based grease kom ntev lawv lifespan.

Ii. Cov Kab Hlau Siv Hlau Hlau Hom thiab Cov Ntawv Siv
1. Sib nqus Groove Cov Kabmob Pob (feem ntau, hom theem pib)
Cov qauv nta: cov pob hlau yob nruab ntawm sab hauv thiab sab nraud ib ncig, ua rau muaj cov qauv yooj yim thiab tus nqi qis.
Cov txiaj ntsig: ntau qhov ntau ntau (tsawg dua lossis sib npaug ntawm 3000 rpm), qis rpm), qis rpm), tsawg dua los yog sib npaug ntawm 1500 kg) thiab maj mam plua plav ib puag ncig.
Qhov tsis zoo: Raug rau deformation nyob rau hauv cov khoom hnyav vim yog cov qauv me me ntawm cov qauv plua plav (cov qauv sib tsoo uas muaj kev cuam tshuam nrog cov impurities).
Cov ntawv thov uas tsim nyog: nruab nrab {{{- qhov chaw tsim khoom siv lub laub thiab khoom lag luam khib nyiab

2. Koob rau cov menyuam bearings (nyiam rau cov khoom siv hnyav)
Cov Txheej Txheem Nta: siv slender rab koob rollers es tsis txhob muaj hlau pob, uas ua rau thaj chaw tiv tauj 3-5 zaug loj dua pob bearings.
Cov txiaj ntsig zoo: tsis tshua muaj load - bearing muaj peev xwm (xws li siv cov khoom siv hnyav rau cov khoom siv ntxhib thiab tshuab cuab yeej ua haujlwm).
Qhov tsis zoo: Ib nyuag ntau dua tig ntau dua li pob bearings, nquag mus rau huab cua sov ntawm kev kub ceev, thiab yuav tsum tau ua kom sov lubrication.
Cov ntawv thov uas tsim nyog: hnyav - Deart Hlau Casters (1,500-3,000 kg load), thiab cov chaw yuav nquag dov kev sib cuag nrog pob zeb.

3. Tapered Rau Cov Menyuam Bearings (Cov Khoom Siv Hnyav + anti - tipping)
Cov Txheej Txheem Nta: Tapered sab hauv thiab sab nraud ib ncig, nrog cov ntaub ntawv npaj hauv cov qauv inclined, muaj peev xwm ntawm cov kabmob ob qho tib si radial thiab axial loads.
Cov txiaj ntsig: thauj khoom {{{{{}} Cov kab mob anti {{} tilting muaj peev xwm tiv thaiv cov roj uas cov menyuam mos.
Qhov tsis zoo: Cov qauv nyuaj, tus nqi siab, thiab meej meej kev hloov kho uas yuav tsum tau rau kev teeb tsa (txwv tsis pub coj los hnav). Haum rau: hnyav {{{{{}} dute overt machinery casters, muaj relves loj (thauj khoom> 3000kg, yuav tsum tau pollover tsis :).

4. Stainless hlau bearings (Tshwj xeeb rau ntub / corrosive ib puag ncig)
Cov Txheej Txheem Nta: Sab hauv thiab sab nraud ib ncig, nrog rau cov chais, txhua yam ua los ntawm cov hlau stainless (304 lossis 316), nrog roj {2} {reassant ntsaws ruaj ruaj.
Cov txiaj ntsig zoo: tsis muaj xeb - tiv taus, muaj kev pheej hmoo ntawm ib puag ncig ntawm cov nag, nrog lub neej ib puag ncig, nrog lub neej ib puag ncig, nrog lub neej ib puag ncig, nrog lub neej ua haujlwm, nrog rau ib lub neej.
Qhov tsis zoo: Tus nqi siab (3 -}} 5 zaug ntawm cov khoom muaj peev xwm zoo dua li cov kabmob sib thooj steel khoom.
Haum rau: Cov chaw ua haujlwm ua zaub mov (dej {- Cov khoom siv ntxuav tes), cov khoom siv sab nraum zoov, thiab cov chaw ua haujlwm sab nraud.

III. Pitfuls kom tsis txhob muaj: kev ua yuam kev ntawm cov nqe lus sib txuas hlau hlau
Qhov muag tsis pom kev mus nrhiav "cov lus qhia siab": tsis tshua muaj cua daj cua dub (xws li tapered rau cov menyuam bearings) muaj nqi thiab muaj siab dov tawm.

Sib sib zog nqus cov groove pob bearings yog kev lag luam ntau dua rau nruab nrab thiab cov khoom poob qis. Kev cai saib xyuas cov ntsaws ruaj ruaj: bearings yam tsis muaj hmoov av npog yuav txeeb vim tsis muaj kev cuam tshuam tsis pub dhau 1-3 lub hlis nyob rau ib puag ncig plua plav. Xaiv cov qauv nrog ZZ lossis 2rs ntsaws ruaj ruaj.

Kev sib xyaw ua ke roj: zoo li qub lithium -}}}}} {tiv taus kub tshaj 120 degree). Hloov mus rau siab - kub polyurae roj teeb hauv qhov siab- qhov chaw ib puag ncig. Zam kev siv calcium {{{{{}}} raws cov roj hauv cov dej noo (nws muag muag thaum raug dej).
