Ob Chav Kab Cylindrical Cov Menyuam Bearings
Taw qhia
Ob chav kab cylindrical cov menyuam bearings tso cai rau qee qhov kev hloov pauv ntawm cov ncej thiab cov kabmob pedestal thiab tuaj yeem siv los ua cov kabmob uas tsis yog qhov chaw.Cov kabmob no muaj qhov zoo ntawm cov qauv compact, loj rigidity, loj bearing muaj peev xwm, me me deformation tom qab loading. , thiab lwm yam, tshwj xeeb tshaj yog haum rau lub tshuab cuab tam spindle txhawb.
Nta thiab Cov txiaj ntsig
● Muaj peev xwm nqa tau siab
Vim lawv cov kab thib ob ntawm cov menyuam, ob kab cylindrical cov menyuam bearings yog tsim rau hnyav radial loads.
● Tsis tshua muaj kev sib txhuam (Roller kawg / flange tiv tauj cheeb tsam)
Qhov qhib flange tsim, ua ke nrog cov menyuam kawg tsim thiab nto tiav, txhawb lubricant zaj duab xis tsim uas ua rau qis kev sib txhuam thiab siab dua axial load nqa peev xwm.
● Lub neej ua haujlwm ntev
Lub logarithmic roller profile txo qhov kev ntxhov siab ntawm cov menyuam / kev sib tw thiab kev nkag siab rau misalignment thiab ncej deflection.
● Txhim kho kev ua haujlwm ruaj khov
Qhov saum npoo tiav ntawm qhov chaw sib cuag ntawm cov chais thiab raceways txhawb kev tsim ntawm hydrodynamic lubricant zaj duab xis.
● Sib cais thiab sib hloov tau
Cov khoom sib cais ntawm ob kab cylindrical cov menyuam bearings yog sib hloov.Qhov no ua kom yooj yim mounting thiab dismounting, nrog rau kev kuaj xyuas.
● Muaj peev xwm ceev
Lub tawb tsim yog tsim rau kev kub ceev, ceev acceleration thiab ncov loads.
Daim ntawv thov
NUU ob kab cylindrical cov menyuam bearings tuaj yeem siv rau hauv cov cuab yeej siv tshuab, lub cev muaj zog, lub cev muaj zog, txo cov gearboxes, vibrating screen, thiab lwm yam.
Kev siv
Ob chav kab cylindrical roller bearing tuaj yeem dais qhov loj du load nyob rau hauv cov kev taw qhia radial.Nws tso cai rau ob kab ntawm DAO rollers nyob rau hauv cov kabmob nrog kev kub ceev yuav tsum tau teem rau hauv txoj kev hla.Qhov hloov pauv zaus thaum lub sij hawm tig yog ob zaug siab dua li ntawm ib kab kab, thiab qhov amplitude yog txo los ntawm 70%.
Muaj ob hom kabmob hauv kev siv: NN30 / W33 thiab NN30K / W33 series.NNU49 / W33 thiab NNU49K / W33 series bearing txheej nplhaib nrog ntug, puab lub nplhaib tuaj yeem sib cais, NN30K / W33 thiab NNU49K / W33 series puab lub nplhaib yog tapered qhov (taper 1: 12), uas tau sib xws nrog cov ntawv xov xwm conical ntawm spindle .Axial txav ntawm lub nplhaib puab tuaj yeem ua rau lub nplhaib puab nthuav kom txo tau cov kabmob clearance thiab txawm pretighten cov kabmob.
Cylindrical bore bearings feem ntau yog kub-loaded, thiab cuam tshuam haum yog siv los txo cov kabmob clearance los yog kom ua tiav lub hom phiaj ntawm preloading.NNU49 series bearings nrog detachable puab nplhaib feem ntau machined ntawm raceway tom qab txhim kho spindle rau puab nplhaib kom tau txais siab ntxaiv kev sib hloov raug.
