Dab tsi yog Cylindrical Cov Menyuam Bearing?
Cylindrical roller bearings yog ib hom kev dov bearings uas muaj cylindrical rollers rau lawv cov khoom dov. Lawv tau tsim los rau kev tiv thaiv siab heev radial loads thaum ua kom muaj kev kub ceev. Core Design: Cov chais no tau raug coj los ntawm cov tav / flanges ntawm cov kabmob rings, whereas lub tawb nta cov menyuam sib cais thiab coj los xyuas kom meej tias lawv txhua tus nyob hauv qhov chaw. Tus nqi ntawm axial load tus kabmob muaj peev xwm tiv taus yog txiav txim siab los ntawm kev npaj ntawm cov tav los ua ib leeg tav, ob leeg tav, lossis tsis muaj tav.
Txoj Cai Ua Haujlwm
Lub load nyob rau hauv cylindrical roller bearings yog kis tau los ntawm cov ntshiab dov txav ntawm lub cylindrical rollers nyob rau hauv raceways ntawm lub puab thiab sab rings. Cov bearings no muaj qhov hnyav radial load vim yog txoj kab kev sib cuag, tsis zoo li cov kabmob ib txwm muaj nrog tib qhov ntev, uas muaj cov ntsiab lus sib cuag. Rollers yog precisely coj los ntawm machined tav. Cages xyuas kom cov haujlwm du ntawm cov bearings.
Core Feature
Cov kabmob radial no muaj lub peev xwm loj radial load: Qhov no yog qhov ruaj khov, thauj khoom -, thiab cov duab- nyob ntawm txoj kab kev sib cuag uas cov menyuam muaj nrog rau txoj kev sib tw. Siab tawv: Ib yam li ntawd, cov kab sib txuas ua rau me me deformation nyob rau hauv nruj, yog li radial stiffness yog zoo heev. Ua haujlwm ntawm kev ceev: Tus tsim tso cai rau qis kev sib txhuam dua li lwm cov menyuam bearings xws li tapered roller bearings, yog li tipping cov nplai hauv kev pom zoo ntawm kev ua haujlwm ceev. Detachable: Feem ntau cov cylindrical roller bearings muaj cov nplhaib sib cais, yam tsawg kawg yog sab hauv thiab feem ntau sab nraud, uas yooj yim rau mounting thiab demounting; ib tug loj ntxiv thaum lub bearing yog txhais tau tias ua raws li ib tug floating kawg los yog nyob rau hauv ib tug confined mounting qhov chaw. rhiab heev rau misalignment: Vim hais tias ntawm lub rugged tsim, nws muaj ib tug tsawg muaj peev xwm los nqus ncej offset los yog vaj tse misalignment (angular misalignment) uas yog vim li cas zoo alignment yog yuav tsum tau thaum txhim kho. Lub ntsiab hom thiab tsim ntawm cylindrical roller bearings muaj ntau heev, nyob rau hauv lawv cov qauv, uas feem ntau txawv ntawm tus naj npawb thiab qhov chaw ntawm cov tav; cov no txiav txim siab axial load peev thiab sib cais.
Ib Kab Cylindrical Cov Menyuam Bearings:
Hom NJ (Ob chav tav ntawm lub nplhaib sab hauv, ib leeg tav ntawm lub nplhaib sab nraud): tuaj yeem tiv taus qhov txwv tsis pub tshaj axial load. Lub nplhaib sab nraud yog sib cais.
Hom NUP (Ob lub tav ntawm lub nplhaib sab hauv nrog lub nplhaib xoob, ob sab tav ntawm lub nplhaib sab nraud): tuaj yeem tiv taus qhov txwv axial loads (ob qho tib si cov lus qhia) thiab tuaj yeem ua haujlwm raws li qhov chaw nyob.
Hom NU (Tsis muaj tav ntawm lub nplhaib sab hauv, ob chav tav ntawm lub nplhaib sab nraud): tuaj yeem tiv taus cov khoom siv hluav taws xob ntshiab. Ob lub nplhaib yog sib cais, ua rau nws ib txwm "floating kawg" bearing.
Ob Chav Kab Cylindrical Cov Menyuam Bearings:
Muab ntau dua radial load peev thiab rigidity. Cov hom muaj xws li NN (tsis muaj tav ntawm lub nplhaib sab hauv) thiab NNU (tsis muaj tav ntawm lub nplhaib sab nraud), feem ntau siv rau hauv cov cuab yeej precision spindles thiab lwm yam kev siv uas xav tau siab heev radial rigidity thiab rotational raug.
Pros thiab Cons
Qhov zoo:
Unmatched radial load- nqa peev xwm.
High radial rigidity thiab qis ua haujlwm deformation.
Relatively zoo ceev muaj peev xwm nyob rau hauv cov menyuam bearing qeb.
Sib cais tsim ua kom yooj yim installation thiab txij nkawm.
Tsawg kev sib txhuam thiab kev ua haujlwm siab.
Qhov tsis zoo:
Feem ntau tsis tuaj yeem tiv taus cov axial dawb huv (tshwj tsis yog rau cov qauv tsim tshwj xeeb) thiab feem ntau yuav tsum tau ua ke nrog cov kabmob thrust.
Heev rhiab heev rau misalignment ntawm ncej thiab vaj tse, yuav tsum tau high alignment raug.
Feem ntau me ntsis noisier tshaj qhov sib sib zog nqus groove pob bearings.
Tsawg siab ntev ntawm kev poob siab loads piv rau spherical roller bearings.
Cov cheeb tsam tseem ceeb ntawm daim ntawv thov
Cylindrical roller bearings yog cov pob txha rau hnyav -lub luag haujlwm, siab -precision radial load daim ntawv thov:
Gearboxes thiab Reducers: Tshwj xeeb tshaj yog rau kev txhawb nqa ncej nyob rau hauv loj industrial gearboxes.
Tshuab Tool Spindles: Ob chav - kab precision cylindrical cov menyuam bearings yog cov khoom tseem ceeb hauv tshuab dhos thiab grinder spindles, muab cov radial rigidity thiab raug.
Cov Khoom Siv Hluav Taws Xob: Siv nyob rau hauv lub tshuab hluav taws xob hydroelectric thiab cua turbine lub ntsiab shafts (feem ntau ua ke nrog thrust bearings).
Cov Hluav Taws Xob Hluav Taws Xob thiab Cov Hluav Taws Xob: Cov kabmob tseem ceeb txhawb nqa lub cev muaj zog / lub tshuab hluav taws xob rotor.
Rolling Mill Roll Neck Bearings: Withstanding enormous dov rog.
Railway Axle Boxes: Bearings rau cov neeg caij tsheb ciav hlau ib txwm muaj thiab cov tsheb thauj khoom thauj.
Khoom Siv Khoom Siv: Kev them nyiaj yug rau crane thiab conveyor pulleys.
Xaus
Cylindrical roller bearings ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv cov ntawv thov uas xav tau lub peev xwm radial quab yuam, siab rigidity, thiab precision. Txawm hais tias lawv xav tau kev txhim kho siab thiab feem ntau tsis haum rau axial loads, lawv qhov kev ua tau zoo tshaj plaws nyob rau hauv cov ntshiab radial loads, siab -ceev adaptability, thiab robustness ua rau lawv nyiam bearing tov rau ntau hnyav industrial thiab siab -precision kis systems.
