Qhov txawv ntawm cylindrical roller bearings thiab koob roller bearings yog dab tsi?

 

Cov kabmob cylindrical

Cov kabmob cylindricalkoom nrog cov bearings precision, thiab lub flange guidance ntawm cov precision-sorted roller post bearing yog tsim los ntawm lub tawb, rollers thiab lub nplhaib qhia ncej, uas tuaj yeem sib cais los ntawm lwm lub nplhaib bearing thiab koom nrog cov bearing sib cais. Hom bearing no yooj yim dua rau kev teeb tsa thiab disassemble, tshwj xeeb tshaj yog thaum cov nplhaib sab hauv thiab sab nraud, shafts thiab tsev yuav tsum tau cuam tshuam.

 

Cov bearings no sib txuas ua kab nrog cov raceways. Lub peev xwm thauj khoom loj heev, thiab nws feem ntau dais cov khoom thauj radial. Tsuas yog ib kab bearings nrog flanges hauv ob lub nplhaib sab hauv thiab sab nraud tuaj yeem nqa cov khoom thauj axial me me lossis cov khoom thauj axial loj; Piv nrog rau lwm cov bearings sib sau ua ke nrog tib qhov loj me, hom bearings no muaj cov yam ntxwv ntawm kev thauj khoom siab, suab nrov hauv qab thiab kev kub ceev, thiab kev sib txhuam ntawm cov khoom dov thiab lub nplhaib flange yog me me, thiab nws yog qhov tsim nyog rau kev tig ceev ceev. Zoo tagnrho rau kev siv nrog txhua yam tshuab precision thiab cov tshuab dov mining. Txawm li cas los xij, cov shafts, cov khoom dov thiab lwm yam khoom cuam tshuam uas phim nrog cov bearings zoo li no yuav tsum tau ua kom raug.

 

Raws li seb lub nplhaib puas muaj flange lossis tsis muaj, nws tuaj yeem muab faib ua NU, NJ, NUP, N, NF thiab lwm yam kab cylindrical roller bearings, thiab NNU, NN thiab lwm yam kab cylindrical roller bearings. Cov kabmob yog ib qho qauv sib cais nrog lub nplhaib sab hauv thiab lub nplhaib sab nraud.

 

Cov kabmob cylindricaltsis muaj flanges nyob rau hauv lub nplhaib sab hauv lossis sab nraud tuaj yeem txav mus los axially thiab tuaj yeem siv ua cov bearings dawb-kawg. Cylindrical roller bearings nrog ob chav flanges ntawm ib sab ntawm lub nplhaib sab hauv thiab sab nraud thiab ib qho flange ntawm sab tod ntawm lub ferrule tuaj yeem tiv taus qee qib ntawm axial load hauv ib qho kev taw qhia. Feem ntau, steel phaj stamping cages siv, lossis tooj liab alloy tig cov cages khoom. Txawm li cas los xij, qee lub cages yog tsim los ntawm kev siv polyamide.

 

Cov kabmob rau cov menyuam uas muaj qhov qhib thiab kaw

 

Koob rau cov menyuam bearings

Cov kabmob koob yog cov kabmob nrog cov menyuam cylindrical, uas yog ob qho tib si nyias thiab ntev piv rau lawv txoj kab uas hla. Cov menyuam no hu ua koob rollers. Txawm hais tias lawv cov ntu me me, cov kabmob muaj peev xwm thauj khoom siab, thiab cov kabmob koob yog nruab nrog cov menyuam nyias thiab ntev (lub menyuam txoj kab uas hla D≤5 hli, L/D≥2.5, L yog qhov ntev ntawm cov menyuam), yog li ntawd, qhov tsim radial yog compact, thiab lawv lub cheeb sab hauv thiab lub peev xwm thauj khoom yog tib yam li lwm hom bearings, nrog rau lub cheeb sab nraud me tshaj plaws, uas yog qhov tshwj xeeb tshaj yog rau cov qauv txhawb nqa nrog qhov ntev radial mounting txwv.

 

Yog li ntawd, cov kabmob koob txhaj tshuaj feem ntau yog siv rau hauv qhov chaw txwv, yog li lawv siv dav hauv tsheb, maus taus, thiab cov tshuab textile. Thiab lub nplhaib sab hauv ntawm cov menyuam koob txhaj tshuaj yog xaiv tau, kom hais meej meej, yog tias qhov nyuaj thiab roughness ntawm tus ncej ua tau raws li qhov yuav tsum tau ua, koj tsis tuaj yeem phim lub nplhaib sab hauv (qhov chaw txwv), tab sis yog tias qib machining ntawm tus ncej qis, lossis mos, koj yuav tsum phim lub nplhaib sab hauv ua qhov chaw sib tw.

 

Qhov sib txawv ntawmcylindrical roller bearings thiab koob roller bearingsyog raws li nram no:

 

1. Lub ntsiab lus ntawm cov kabmob cylindrical roller yog ib lub roller tapered; Cov ntsiab lus ntawm cov kabmob koob yog cov menyuam zoo li koob;

 

2. Cov qauv ntawm cov cylindrical roller bearings loj dua li ntawm cov koob txhaj tshuaj bearings;

 

3. Ntxiv rau lub zog radial, lub cylindrical roller kuj tseem tuaj yeem tiv taus lub zog axial, thaum lub koob roller bearing tsuas tuaj yeem dais lub zog radial;

 

4. Cov kabmob cylindrical roller bearings raug muab faib ua ib kab, ob kab thiab ntau kab, uas yog siv rau ntau qhov chaw thiab lub sijhawm sib txawv;

 

5. Qhov ceev ua haujlwm ntawm cov cylindrical roller bearings siab dua li ntawm cov koob txhaj tshuaj bearings;

 

6. Cov kabmob cylindrical roller feem ntau yog ua los ntawm cov hlau zoo thiab cov hlau tshwj xeeb; Cov kabmob nyias-walled koob roller yog stamped los ntawm cov phaj hlau. 

 

Thaum twg yuav siv nws

 

Hauv kev tsim kho tshuab, qhov loj ntawm lub qag feem ntau yog txiav txim siab ua ntej, thiab tom qab ntawd cov kabmob dov raug xaiv raws li qhov loj ntawm lub qag. Txawm li cas los xij, thaum cov kabmob raug txwv hauv qhov kev taw qhia ntawm lub tshuab, cov kabmob koob, pob lossis cov kabmob menyuam ntawm cov koob sib dua thiab ultra-light raug xaiv; Thaum qhov chaw axial ntawm cov kabmob hauv lub tshuab raug txwv, cov koob sib dua lossis nqaim dua ntawm cov pob lossis cov kabmob menyuam muaj.

 

Cov khoom siv radial koob rau cov menyuam thiab lub tawb, cov kabmob sab nraud uas muaj cov cim stamped, cov kabmob ruaj khov rau cov menyuam, cov kabmob thrust koob rau cov menyuam yog siv dav hauv lub cev kis, lub cev tsav tsheb, lub cav maus taus txuas pas nrig ntawm lub tsheb thiab cov tshuab siv hauv kev tsim kho, thiab lwm yam, thiab tsim nyog rau cov xwm txheej uas muaj qhov chaw me me thiab muaj peev xwm loj. Cov kabmob koob rau cov menyuam muaj cov menyuam nyias thiab ntev (qhov ntev ntawm cov menyuam yog 3 ~ 10 npaug ntawm txoj kab uas hla, thiab txoj kab uas hla feem ntau tsis pub ntau tshaj 5 hli), yog li cov qauv radial yog compact, thiab nws qhov loj me ntawm txoj kab uas hla sab hauv thiab lub peev xwm thauj khoom yog tib yam li lwm hom kabmob, thiab txoj kab uas hla sab nraud yog qhov me tshaj plaws, uas yog tshwj xeeb tshaj yog rau cov txiaj ntsig txhawb nqa qhov twg qhov loj me ntawm kev teeb tsa radial txwv.
