Taw Qhia Cov Kabmob

Sib sib zog nqus groove pob kabmob: yav tas los hu ua ib kab radial npas kabmob, nws yog qhov feem ntau siv cov kabmob sib tw. Nws cov yam ntxwv tsis tshua muaj kev sib txhuam thiab kev kub ceev. Thaum cov kabmob tsuas yog dais radial load, lub sib tiv tauj lub xoom yog xoom. Thaum lub sib sib zog nqus groove pob kabmob muaj radial loj tshem tawm, nws muaj qhov ua haujlwm ntawm lub kaum sab xis tiv thaiv kabmob thiab tuaj yeem dais loj axial load.

Nws tus kheej cov pob zoo sib xws: nrog cylindrical qhov thiab conical lub qhov ob hom ntawm tus qauv, cov khoom siv tawb muaj steel phaj, cob hluavtaws thiab lwm yam. Nws tus yam ntxwv yog qhov kev sib tw ntiv nplhaib sab nraud yog kheej kheej thiab muaj kev muaj peev xwm ntawm kev coj tus kheej. Nws tuaj yeem them qhov teeb meem uas tshwm sim los ntawm kev sib txawv nruab nrab thiab lub hauv siab, tab sis kev sib txheeb ntawm cov npoo thiab puab ib ncig yuav tsum tsis pub tshaj 3 degrees. Nws yog feem ntau dais cov radial load thiab tuaj yeem tiv taus cov kab xaum me me nyob rau tib lub sijhawm. Lub hleb txav ntawm txoj haujlwm (lub plhaub) raug txwv nyob rau hauv txoj haujlwm tshem tawm, thiab muaj txoj haujlwm ua haujlwm ntawm tus kheej. Nws tuaj yeem ua haujlwm ib txwm nyob rau qhov xwm txheej me me ntawm sab hauv thiab sab nraud. Nws yog qhov haum rau qhov chaw uas muaj cov coaxiality ntawm lub rooj zaum qhov rooj tsis tuaj yeem lav.

Cov kabmob cylindrical cov kabmob: lub caij dov yog lub centripetal dov cov kabmob ntawm cov menyuam cylindrical. Cov qauv sab hauv ntawm cov menyuam cylindrical cov menyuam tau yoog kev sib txig sib dhos ntawm cov chais, thiab lub tog raj lossis txuas ntxiv yog nruab nrab ntawm cov dov, uas tuaj yeem tiv thaiv txoj kev tawm ntawm cov menyuam lossis kev sib txhuam ntawm cov dov, thiab tiv thaiv qhov nce ntawm qhov sib hloov ntawm qhov sib hloov. Cov. Cylindrical roller thiab raceway yog kab sib kis. Lub peev xwm loj ntim, feem ntau dais radial load. Kev txhuam txhuam ntawm lub ntsiab lus dov thiab lub nplhaib sib dhos yog me me, uas tsim nyog rau kev sib hloov ceev. Raws li seb lub nplhaib muaj flange, nws muaj peev xwm muab faib ua ib kab cylindrical roller bearings xws li Nu, NJ, NUP, N, NF, thiab ob chav kab cylindrical roller bearings xws li NNU thiab NN. Cov kabmob yog cov qauv sib cais ntawm lub nplhaib puab thiab sab hauv.

Koob rau cov menyuam: cov menyuam cov kabmob nrog cylindrical roller, txheeb ze rau nws txoj kab uas hla, cov hlau yog nyias thiab ntev. Qhov zoo li no ntawm cov menyuam yog hu ua rab koob roller. Txawm hais tias nws muaj qhov sib hla me me, qhov kev coj tus kheej tseem muaj qhov siab thauj khoom hnyav. Cov koob txhaj rau cov menyuam tau muab tso nrog cov menyuam nyias nyias thiab ntev (cov kab uas hla D ≤ 5mm, L / D ≥ 2.5, l yog qhov ntev ntawm cov menyuam). Yog li no, tus qauv radial yog compact. Thaum lub puab taub loj thiab loj ntim muaj peev xwm yog tib yam li lwm yam ntawm cov kabmob, sab nraud txoj kab uas hla yog qhov tsawg tshaj plaws, uas tshwj xeeb tshaj yog haum rau cov qauv kev txhawb nqa nrog txwv radial installation loj. Cov kabmob tsis muaj lub nplhaib sab hauv lossis rab koob roller thiab tawb sib dhos tuaj yeem xaiv tau raws li nyias muaj nyias daim ntawv thov. Lub sijhawm no, cov ntawv xov xwm saum npoo thiab lub plhaub lub npoo qhov sib txuam nrog cov kabmob tau ncaj qha siv sab hauv thiab sab nraud dov sab nraud ntawm cov kabmob. Txhawm rau kom paub tseeb tias tib lub peev xwm thiab kev ua haujlwm zoo li cov kabmob nrog lub nplhaib, lub siab tawv, kev siv lub tshuab kom raug thiab qhov chaw zoo ntawm cov haiv neeg ntawm sab qaum los yog lub plhaub sab nraud yuav tsum zoo ib yam li ntawm lub nplhaib cov kabmob. Qhov no zoo ntawm kev coj tus kheej tuaj yeem tsuas dais radial load.

Tapered cov menyuam kabmob: nws belongs rau lwm hom kabmob. Sab hauv thiab puab ncig ntawm cov kabmob muaj tapered raceways. Cov kabmob no muaj peev xwm muab faib ua ib kab, ob chav kab thiab plaub leej tapered cov menyuam tau cov kabmob. Tib kab tapered rau cov menyuam tau cov kabmob radial load thiab axial ua ke load hauv ib qho kev taw qhia nkaus xwb. Thaum cov kabmob tiv thaiv cov kabmob radial, nws yuav tsim cov khoom siv axial, yog li nws xav tau lwm cov kabmob uas tuaj yeem tiv taus cov kabmob quab yuam los sib luag. Piv nrog angular hu npas kabmob, lub peev xwm muaj peev xwm loj, qhov kev txwv ceev yog tsawg, nws muaj peev xwm dais axial thauj nyob rau hauv ib qho kev taw qhia, thiab tuaj yeem txwv axial tawm ntawm cov ncej lossis lub plhaub hauv ib qho kev taw qhia.

Kheej kheej cov menyuam: cov kabmob muaj ob txoj kab ntawm rollers, ib qho chaw sib dhos ntawm cov nplhaib sab nraud thiab ob txoj kev sib tw sab hauv ntawm lub kaum sab xis nrog cov kabmob sib dhos. Lub chaw kheej kheej ntawm txoj kab ntawm lub nplhaib lub ntsej muag sab nrauv yog nyob ntawm phau ntawv cov kabmob. Yog li ntawv cov kabmob yog cov kabmob ntawm tus kheej thiab tsis rhiab rau kev ua haujlwm ntawm kev ua haujlwm tsis ncaj ntawm tus ncej thiab cov kabmob lub pob, uas yuav tshwm sim los ntawm qee yam xws li kev hloov mus los. Kheej kheej kheej cov menyuam cov kabmob tau zoo tsim, uas tuaj yeem tiv taus tsis tsuas yog lub zog siab radial, tab sis kuj tseem hnyav axial load ua haujlwm nyob rau hauv ob qho kev qhia.

Thrust pob kabmob:nws yog tsim los ua kom ntuav lub nrawm ntawm kev kub ceev, thiab yog tsim ntawm washer nplhaib nrog raceway zawj ntawm pob dov. Vim hais tias lub nplhaib muaj cushion zoo li tus kheej, lub pob thawb lub pob tau muab faib ua ob hom: tiaj tiaj hauv qab cushion hom thiab nws tus kheej-kheej kheej kheej kheej hom cushion. Tsis tas li, cov kabmob tuaj yeem dais axial load tab sis tsis dhau radial load. Nws yog tsuas yog tsim nyog rau cov seem nrog qeeb ceev thiab axial load.

Pov thawb cov menyuam kev coj tus kheej: cov kabmob yog kwv yees li qhov sib npaug ntawm cov kabmob ntawm tus kheej. Qhov kev sib tw sab saum toj ntawm lub nplhaib cov kabmob yog kheej kheej rau nruab nrab ntawm lub taw tes sib luag nrog nruab nrab ncej ntawm cov kabmob. Cov menyuam ntawm hom kabmob no yog kheej kheej. Yog li ntawd, nws muaj qhov ua haujlwm tsis siv neeg lub hauv nruab nrab thiab tsis rhiab rau coaxiality thiab ncej deflection. Cov kabmob no feem ntau yog siv hauv cov roj drilling rig, hlau thiab hlau tshuab, tshuab ua hluav taws xob, lub cev muaj zog, ntsug tshuab, roj av kiv cua, ntauwd crane, extrusion xovxwm, thiab lwm yam.

Ntsawj tapered cov menyuam kabmob: thrust tapered cov menyuam cov kabmob tuaj yeem tsim lub thooj sib txuam ntawm cov khoom muaj roj. Qhov no qhov kev coj tus kheej tuaj yeem thev cov axial hnyav, yog qhov ua rau tsis tuaj yeem cuam tshuam rau lub nra, thiab muaj kev nruj zoo. Vim hais tias cov ntxuag caij hauv lub nruas tapered cov menyuam cov kabmob yog tapered cov menyuam, hauv cov qauv, yob generatrix thiab raceway generatrix ntawm washer hloov ntawm cov kabmob
