Bearings yog ib qho tseem ceeb ntawm cov tshuab niaj hnub no. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhawb nqa lub tshuab tig lub cev, txo cov kev sib txhuam coefficient thaum nws txav mus los, thiab xyuas kom meej nws cov kev sib hloov raug.

Raws li qhov sib txawv ntawm kev sib txhuam ntawm cov khoom txav, bearings tuaj yeem muab faib ua ob pawg: dov bearings thiab zawv zawg bearings.

Feem ntau siv nyob rau hauv dov bearings yog sib sib zog nqus groove pob bearings, cylindrical roller bearings thiab thrust pob bearings. Ntawm lawv, dov bearings tau tsim qauv thiab serialized, thiab feem ntau yog tsim los ntawm plaub ntu: lub nplhaib sab nraud, lub nplhaib puab, dov lub cev thiab lub tawb.

Sib sib zog nqus groove pob bearingsFeem ntau dais radial load, thiab tuaj yeem dais radial load thiab axial load tib lub sijhawm. Thaum nws tsuas yog raug rau radial load, lub kaum sab xis yog xoom. Thaum qhov sib sib zog nqus groove pob bearing muaj qhov loj radial clearance, nws muaj qhov ua tau zoo ntawm kev sib cuag ntawm lub kaum sab xis thiab tuaj yeem dais qhov loj axial load. Kev sib txhuam coefficient ntawm qhov sib sib zog nqus groove pob bearing yog me me thiab qhov txwv ceev kuj tseem siab.

Sib sib zog nqus groove pob bearings yog cov sawv cev tshaj plaws dov bearings thiab tau siv dav. Nws yog qhov tsim nyog rau kev ua haujlwm siab thiab txawm tias muaj kev kub ceev heev, thiab ruaj khov heev yam tsis muaj kev saib xyuas ntau zaus. Hom kabmob no muaj kev sib txhuam me me, kev txwv siab ceev, qauv yooj yim, tsis tshua muaj nqi tsim khoom thiab yooj yim rau kev ua tiav siab precision. Qhov luaj li cas thiab daim ntawv sib txawv, thiab yog siv nyob rau hauv precision instruments, low-noise motors, tsheb, maus taus thiab machinery thiab lwm yam industries, thiab yog cov feem ntau lug siv hom bearings nyob rau hauv lub machinery kev lag luam. Feem ntau dais radial load, tab sis kuj dais tus nqi ntawm axial load.

Cylindrical roller bearings, cov ntsiab lus dov yog radial dov bearings ntawm cylindrical rollers. Cylindrical rollers thiab raceways yog linear contact bearings. Load peev, feem ntau dais radial load. Kev sib txhuam ntawm cov khoom dov thiab cov tav ntawm lub nplhaib yog me me, uas yog tsim rau kev sib hloov ceev. Raws li seb lub nplhaib muaj ribs lossis tsis, nws tuaj yeem muab faib ua ib kab bearings xws li NU, NJ, NUP, N, NF, thiab ob kab kab xws li NNU thiab NN.

Cylindrical roller bearings tsis muaj ribs ntawm lub nplhaib sab hauv lossis sab nraud, lub nplhaib sab hauv thiab sab nrauv tuaj yeem txav mus rau qhov kev taw qhia axial, yog li lawv tuaj yeem siv los ua cov kabmob dawb kawg. Cylindrical roller bearings nrog ob lub tav ntawm ib sab ntawm lub nplhaib puab thiab sab nraud thiab ib tus tav ntawm ib sab ntawm lub nplhaib tuaj yeem tiv taus qee qhov kev thauj khoom axial hauv ib qho kev coj. Feem ntau, steel stamping tawb yog siv, los yog siv tooj liab alloy tig khoom tawb. Txawm li cas los xij, kuj tseem muaj ib feem ntawm kev siv polyamide ua lub tawb.

Thrust pob bearings yog tsim los tiv thaiv thrust loads thaum lub sijhawm ua haujlwm siab, thiab muaj cov tshuab ntxhua khaub ncaws zoo li ferrules nrog raceway grooves rau pob dov. Txij li thaum lub ferrule yog nyob rau hauv daim ntawv ntawm lub rooj zaum cushion, lub thrust pob bearing yog muab faib ua ob hom: ca lub rooj cushion hom thiab nws tus kheej-aligning spherical lub rooj cushion hom. Tsis tas li ntawd, cov kabmob no tuaj yeem tiv taus axial loads, tab sis tsis yog radial loads.

Thrust pob bearingsyog tsim los ntawm peb qhov chaw: lub rooj ntxhua khaub ncaws, ncej ntxhua khaub ncaws thiab steel pob tawb sib dhos. Lub tshuab ntxhua khaub ncaws sib xyaw nrog cov ncej thiab lub nplhaib lub rooj zaum sib phim nrog lub tsev. Thrust pob bearings tsuas yog tsim rau cov khoom uas dais axial load ntawm ib sab thiab muaj kev ceev ceev, xws li crane hooks, ntsug dej twj, ntsug centrifuges, jacks, low-speed reducers, thiab lwm yam. ntawm cov kabmob yog sib cais thiab tuaj yeem sib dhos thiab disassembled nyias.
