Bearings yog cov khoom tseem ceeb hauv cov cuab yeej siv tshuab. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhawb nqa lub tshuab tig lub cev kom txo tau qhov sib txhuam coefficient ntawm cov khoom siv thauj khoom thaum lub sijhawm sib kis ntawm cov khoom siv.
Bearings tau muab faib ua radial bearings thiab thrust bearings raws li qhov sib txawv load-nqa cov lus qhia los yog nominal contact angles.
Raws li hom dov cov ntsiab lus, lawv tau muab faib ua: pob bearings thiab cov menyuam bearings.
Raws li seb lawv puas tuaj yeem ua kom haum, lawv tau muab faib ua: tus kheej-aligning bearings thiab non-aligning bearings (rigid bearings).
Raws li tus naj npawb ntawm kab ntawm dov cov ntsiab lus, lawv tau muab faib ua: ib kab bearings, ob-kab bearings, thiab ntau kab bearings.
Raws li seb cov khoom puas tuaj yeem sib cais, lawv muab faib ua: sib cais bearings thiab tsis-separable bearings.
Kuj tseem muaj kev faib tawm raws li cov qauv tsim thiab qhov loj me.
Kab lus no feem ntau qhia cov yam ntxwv, qhov sib txawv thiab kev siv ntawm 14 hom bearings.
8 Thrust pob bearing
Thrust roller bearings yog siv rau shafts uas dais feem ntau axial load thiab ua ke meridional load, tab sis meridional load yuav tsum tsis pub tshaj 55% ntawm cov axial load. Piv nrog rau lwm cov thrust roller bearings, hom kabmob no muaj kev sib txhuam coefficient qis dua, kev sib hloov ceev dua, thiab muaj peev xwm kho tau. Cov rollers ntawm 29000 bearing yog asymmetric spherical rollers, uas tuaj yeem txo tus txheeb ze zawv zawg ntawm tus pas thiab txoj kev sib tw thaum lub sijhawm ua haujlwm. Cov rollers yog ntev thiab muaj ib txoj kab uas hla loj. Lawv muaj ib tug loj tus naj npawb ntawm rollers thiab ib tug loj load peev xwm. Lawv feem ntau yog lubricated nrog roj. Roj lubrication tuaj yeem siv rau ntawm qhov nrawm.
Main siv: hydraulic generators, crane hooks.
9 Cylindrical Cov Menyuam Bearings
Cov rollers ntawm cylindrical roller bearings feem ntau yog coj los ntawm ob sab ntawm lub nplhaib bearing. Lub tawb rau cov menyuam thiab cov nplhaib qhia ua ib qho kev sib dhos uas tuaj yeem sib cais los ntawm lwm lub nplhaib bearings thiab yog cov kabmob sib cais.
Cov kabmob zoo li no yooj yim dua rau kev txhim kho thiab tshem tawm, tshwj xeeb tshaj yog thaum muaj kev cuam tshuam zoo ntawm cov nplhaib sab hauv thiab sab nrauv, cov ncej thiab lub plhaub yuav tsum tau ua. Hom kabmob no feem ntau tsuas yog siv los dais radial loads. Tsuas yog ib leeg-kab bearings nrog tav ntawm ob sab hauv thiab sab nrauv tuaj yeem dais me me axial loads lossis loj sib quas ntus axial loads.
Kev siv loj: cov motors loj, tshuab cuab yeej spindles, qag thawv, diesel cav crankshafts, tsheb, kis lub thawv nrog bearings, thiab lwm yam.
10 Plaub taw tes tiv thaiv pob bearings
Nws tuaj yeem dais radial load thiab bidirectional axial load. Ib qho kev coj tus kheej tuaj yeem hloov qhov kev sib cuag ntawm lub npas kabmob ntawm kev sib xyaw ua ke lossis rov qab ua ke. Nws yog tsim rau bearing ntshiab axial load los yog hluavtaws load nrog loj axial load tivthaiv. Hom kabmob no tuaj yeem tiv taus txhua qhov kev taw qhia. Ib qho ntawm cov ces kaum sib cuag tuaj yeem tsim tau thaum muaj kev thauj khoom axial, yog li lub ferrule thiab pob yog ib txwm nyob rau hauv kev sib cuag nrog peb cov ntsiab lus ntawm ob sab ntawm ib qho kev sib cuag.
Kev siv loj: dav hlau dav hlau cav, roj turbines.
11 Thrust cylindrical cov menyuam bearings
Nws muaj lub nplhaib zoo li lub nplhaib sib tw (ntiv nplhaib ncej, lub nplhaib lub rooj zaum) thiab cylindrical cov menyuam thiab cov khoom hauv tawb. Cov menyuam cylindrical tau txais kev ua haujlwm ntawm lub ntsej muag, yog li lub siab ntawm cov menyuam thiab qhov chaw sib tw yog sib npaug, thiab nws tuaj yeem tiv taus ib-txoj kev axial load. Nws muaj peev xwm loj axial load thiab muaj zog axial rigidity.
Main siv: roj drilling rigs, hlau thiab steel ua machinery.
12 Thrust koob rau cov menyuam bearing
Separable bearings yog tsim los ntawm raceway rings, koob rollers thiab lub tawb sib dhos, thiab tuaj yeem ua ke nrog cov khoom sib tw nyias nyias los yog txiav-ua tiav tuab raceway rings. Tsis-separable bearings yog ib qho bearings uas muaj precision stamped raceway rings, koob rollers thiab tawb sib dhos. Lawv tuaj yeem tiv taus unidirectional axial loads. Hom kabmob no siv qhov chaw me me thiab yog qhov tsim nyog rau lub compact tsim ntawm machinery. Feem ntau ntawm lawv tsuas yog siv rab koob rau cov menyuam thiab lub tawb sib dhos, thiab lub mounting nto ntawm lub ncej thiab vaj tse yog siv los ua qhov chaw sib tw.
Kev siv tseem ceeb: kis tau tus mob rau tsheb, cultivators, tshuab cuab yeej, thiab lwm yam.
13 Thrust tapered cov menyuam bearings
Hom kabmob no yog nruab nrog truncated cone-shaped rollers (qhov loj kawg yog kheej kheej). Cov chais yog raug coj los ntawm cov tav ntawm lub nplhaib raceway (shaft nplhaib, lub nplhaib lub rooj). Tus qauv tsim kom ntseeg tau tias qhov chaw sib tw ntawm lub nplhaib ncej thiab lub nplhaib lub rooj zaum thiab qhov chaw dov ntawm cov chais Lub apex ntawm txhua qhov conical nto intersects ntawm ib qho taw tes ntawm kab nruab nrab ntawm cov kabmob. Ib-txoj kev bearings tuaj yeem dais ib-txoj kev axial loads, thiab ob-txoj kev bearings tuaj yeem dais ob-txoj kev axial loads.
Lub hom phiaj tseem ceeb:
Ib txoj kev: Crane nuv, roj drilling rig tig.
Ob qho kev qhia: dov zeb yob caj dab.
14 Ntxig spherical pob bearing nrog lub rooj zaum
Lub rooj zaum spherical pob bearing yog tsim los ntawm lub pob kheej kheej kheej kheej nrog cov ntsaws ruaj ruaj ntawm ob sab thiab cam khwb cia (los yog steel phaj stamped) bearing lub rooj. Cov qauv sab hauv ntawm lub pob kheej kheej kheej kheej yog tib yam li qhov sib sib zog nqus groove pob bearing, tab sis lub nplhaib puab ntawm cov kabmob no yog dav dua lub nplhaib sab nraud. Lub nplhaib sab nrauv muaj ib lub ntsej muag kheej kheej, uas tuaj yeem ua raws li cov concave kheej kheej ntawm lub rooj zaum bearing.
Kev siv tseem ceeb: mining, metallurgy, kev ua liaj ua teb, tshuaj lom neeg kev lag luam, textile, luam ntawv thiab dyeing, conveying machinery, thiab lwm yam.
