Pob Bearings

1.Angular contact pob bearings
Cov hom bearings no muaj raceways ntawm ob sab hauv thiab sab nraud rings uas tau tsiv mus rau ib leeg nyob rau hauv lub bearing axis kev taw qhia. Qhov no txhais tau hais tias cov hom bearings no tau tsim nyob rau hauv xws li ib txoj kev uas lawv tuaj yeem ua kom haum cov khoom sib xyaw ua ke (ib txhij ua axial thiab radial loads). Cov hom bearings no muaj nyob rau hauv cov qauv tsim sib txawv, nrog kev tiv thaiv los yog cov ntsaws ruaj ruaj.
hese tsis tsuas yog tiv thaiv kev kis kab mob tab sis kuj ua raws li cov khoom khaws cia rau lubricants. Cov kabmob no yog tsim los ntawm cov ntaub ntawv hauv qab no: cov khoom siv ceramic hybrid, stainless hlau, cadmium, lossis yas, thiab tej zaum plated nrog chrome, lossis lwm yam khoom siv. Lawv kuj tuaj yeem rov lubricated, pre-lubricated, los yog muaj peev xwm ua tau zoo lubrication. Angular contact bearings raug cais ntxiv rau hauv cov subtypes hauv qab no:

2.Single kab angular contact bearing
Cov hom bearings no suav nrog ntau lub npas los muab lub peev xwm thauj khoom hnyav, thiab lawv tuaj yeem ua raws li cov axial loads hauv ib qho kev taw qhia nkaus xwb. Lawv feem ntau raug kho raws li qhov kev coj tus kheej thib ob, thiab muaj cov nplhaib tsis sib cais.

3.Ob kab angular hu rau pob bearing
Cov kabmob no muaj cov qauv tsim uas sib haum rau ob kab ib kab bearings teem rov qab-rau-rov qab, tab sis qhov twg ob leeg bearings siv ntau qhov chaw axial. Lawv tuaj yeem haum axial thiab radial loads nyob rau hauv ob qho tib si kev taw qhia thiab tilting lub sij hawm.

4.Four ntsiab lus angular contact bearing
Cov hom kabmob no muaj cov qauv tsim uas tso cai rau lawv los txhawb nqa axial loads nyob rau hauv txhua qhov kev qhia thiab lawv lub peev xwm nqa tau siab. Lawv tuaj yeem txhawb nqa ib qho radial load uas txwv rau qhov muab axial load, lawv sib cais, thiab siv qhov chaw axial tsawg tshaj li ob kab kab bearings.

5.Deep groove pob bearing
Cov hom bearings no yog hom pob bearings feem ntau siv. Lawv muaj nyob rau hauv cov ntaub thaiv npog, foob, thiab snap-ring kev npaj. Qhov ntev ntawm cov haiv neeg nyob rau hauv cov hom bearings zoo sib xws rau qhov ntev ntawm lub pob. Lawv kuj muaj peev xwm txhawb nqa hnyav. Sib sib zog nqus groove bearings muab ob qho tib si axial thiab radial kev txhawb nqa.
Txawm li cas los xij, cov qib txheeb ze ntawm cov khoom no tsis tuaj yeem hloov pauv vim tias lub kaum sab xis sib cuag tsis tuaj yeem hloov kho. Sib sib zog nqus groove pob bearings raug cais ntxiv rau hauv cov chav kawm hauv qab no.

6. Ib kab sib sib zog nqus groove pob bearing
Cov no yog cov feem ntau hom ntawm tag nrho cov bearings. Lawv tau siv dav. Muaj cov arcs ntawm ib lub vojvoog uas loj dua me ntsis ntawm cov pob ntawm cov raceway grooves ntawm sab hauv thiab sab nraud. Txhawm rau ntxiv rau sab saum toj ntawm radial loads, qhov kev txiav txim ntawm axial loads tuaj yeem ua rau ob qho tib si. Cov hom pob bearings no muaj lub zog qis, thiab zoo heev rau cov ntawv thov uas yuav tsum tau muaj kev kub ceev thiab tsis muaj zog poob. Txhawm rau ntxiv rau sab saum toj ntawm cov kabmob qhib, cov kabmob no feem ntau muaj cov ntaub thaiv npog ua los ntawm cov hlau lossis cov roj hmab ntsaws rau ntawm ib sab lossis ob sab thiab ua ntej lubricated nrog roj.

7.Ob kab sib sib zog nqus groove pob bearing
Cov hom pob bearings no muaj cov qauv tsim uas sib haum rau ib kab sib sib zog nqus groove pob bearings. Lawv muaj cov kab sib tw uas sib sib zog nqus thiab tsis muaj kev cuam tshuam thiab muaj kev sib raug zoo nrog cov pob. Qhov no ua rau cov bearings kom haum axial thiab radial loads nyob rau hauv ob qho tib si kev taw qhia.
Ob chav kab sib sib zog nqus groove pob bearings zoo kawg nkaus haum cov kabmob uas muaj qhov tsis txaus thauj khoom ntawm ib kab. Ob chav kab sib sib zog nqus groove bearings yog me ntsis dav dua piv rau ib kab bearings nyob rau hauv 63 thiab 62 series, rau tib bore thiab sab nraud txoj kab uas hla. Tab sis lawv muaj lub peev xwm thauj khoom uas yog qhov siab heev. Cov hom pob bearings no tsuas yog pom raws li cov kabmob qhib (tsis muaj cov ntsaws ruaj ruaj lossis cov ntaub thaiv npog).

8.Duplex pob bearing
Cov hom pob bearings no yog tsim los ntawm kev sib txuas ntawm ob lub angular contact bearings. Cov kev sib txuas uas muaj peev xwm muaj xws li rov qab-rau-rov qab (hom DB), lub ntsej muag-rau-lub ntsej muag (hom DF) nrog lub ntsej muag ntawm lub nplhaib sab nrauv ua ke, lossis ob lub ntsej muag pem hauv ntej nyob rau hauv tib txoj kev (hom DT).
DB thiab DF duplex bearings tuaj yeem nqa axial thiab radial loads hauv ob qho tib si. Thaum lub axial load muaj zog, thiab nyob rau hauv ib qho kev taw qhia thiab lub imposition ntawm load sib npaug zos rau txhua bearing yog tsim nyog, hom DT yog siv.

9.Hybrid pob bearings siv cov khoom siv ceramic
Ceramic bearing npas tuaj yeem muaj qhov hnyav txog li 40% tsawg dua cov hlau, nyob ntawm seb cov khoom thiab qhov loj me. Qhov no ua rau txo qis ntawm centrifugal loading thiab skidding, yog li hybrid ceramic pob bearings tuaj yeem ua haujlwm 20% mus rau 40% sai dua li cov kabmob sib xyaw. Lub ntsiab lus ntawm qhov no yog tias, lub zog tawm sab hauv tawm tsam lub pob thaum lub sij hawm spinning ntawm cov kabmob, los ntawm kev sib tw sab nrauv yog tsawg dua.
Qhov kev txo qis hauv kev quab yuam no yuav txo qhov kev sib txhuam nrog rau kev ua haujlwm dov. Cov kabmob tau tso cai kom tig nrawm dua los ntawm cov khoom sib zog, thiab cov kabmob siv lub zog tsawg los tswj nws qhov nrawm. Cov pob zeb ceramic yog qhov nyuaj dua piv rau cov haiv neeg. Ceramic hybrid pob bearings yog tsim los ntawm cov hlau sab hauv thiab sab nrauv thiab cov ceramic muaj zog dua cov hlau. Tab sis nws kuj tseem tawv dua, ua rau muaj kev ntxhov siab ntau ntxiv ntawm cov nplhaib, thiab yog li lub peev xwm thauj khoom poob qis.

10.Miniature bearings
Cov no yog cov kabmob me me uas muaj cov pob ua lawv cov khoom dov. Cov kabmob me me yog qee zaum hu ua micro bearings lossis ntsuas cov kabmob nrog cov nplhaib sab hauv thiab sab nrauv, snap rings, pob, thiab cov khoom tuav. Cov hom bearings no yog siv nyob rau hauv industrial thiab kho mob handpieces thiab lwm yam precision daim ntaub ntawv. Pob kabmob tsim muaj xws li angular, radial, thrust, thiab pivot.
Cov kabmob me me yog tsim raws li tus qauv European metric qhov ntau thiab tsawg hauv qab 20 millimeters. Lawv txawv ntawm ib yim ntawm ib nti hauv lawv txoj kab uas hla tag nrho mus rau 20 millimeters hauv lawv qhov loj me. Ib qho ntawm qhov me me tshaj plaws yog bore ntawm 0.04 thiab tag nrho qhov loj ntawm ib feem yim ntawm ib nti. Vim nws qhov tshwj xeeb loj, hom kabmob no muaj txiaj ntsig zoo rau ntau yam kev siv.
Cov kabmob me me yog tsim los ua kom tiav kev ua haujlwm siab uas txhim khu kev qha rau nruab nrab thrust thiab radial loads ntawm qis kev khiav hauj lwm torque. Yog li ntawd, cov yam ntxwv tseem ceeb tshaj plaws nrog cov kabmob me me yog qhov tseeb, ceev, thiab lub neej ntev. Ntxiv rau sab saum toj, qhov ntsiag to ntawm cov kabmob khiav ntawm kev kub ceev kuj tseem yog qhov tseem ceeb heev. Cov kabmob me me tsis siv rau hauv cov ntawv thov uas muaj cov khoom hnyav, thiab vim tias siv cov khoom siv me me, cov hlau tsis muaj steel yog siv los tsim ntau cov kabmob.

11.Precision pob bearings
Cov hom bearings no tso cai rau kev nplua precision thiab kam rau ua. Precision pob bearings yog qhov zoo tagnrho rau cov ntawv thov uas muaj cov kev xav tau nruj rau kev ceev thiab kev taw qhia raug. Precision pob bearings muaj nyob rau hauv ob hom tseem ceeb uas yog angular hu bearings thiab sib sib zog nqus groove bearings. Sib sib zog nqus groove pob bearings muaj tag nrho lub xub pwg nyom ntawm ob sab ntawm txoj kev sib tw ntawm lub nplhaib sab hauv thiab sab nrauv, tso cai rau kev sib ntxiv ntawm cov ntsaws ruaj ruaj lossis cov ntaub thaiv npog yooj yim.
Cov bearings no muaj peev xwm tuav cov thrust loads, radial loads, los yog ua ke ntawm ob qho tib si. Lawv muaj nyob rau hauv ntau qhov ntau thiab tsawg uas suav nrog me me precision bearings, thiab muaj nyob nrog ntau hom tawb. Sib sib zog nqus groove bearings yog ntau yam tsis tshua muaj ntau yam thiab pom ntawm cov kabmob uas siv ntau tshaj plaws.
Angular contact bearings yog tsim los ntawm ib lub nplhaib ua tiav; lwm lub nplhaib tsis tuaj yeem tshwm sim vim nws raug tshem tawm ib nrab lossis tag nrho. Qhov no nyob rau hauv lem yuav cia lawv muaj ib lub pob loj, uas muab ntau dua load peev xwm thiab ceev muaj peev xwm. Kuj tseem muaj ntau lub tawb tsim uas muaj kom tau raws li cov kev xav tau ceev ceev.
Angular contact bearings tuaj yeem txhawb nqa kev thauj khoom lossis kev sib xyaw ntawm ob qho tib si radial thiab thrust loads, tab sis lawv tsis muaj peev xwm txhawb nqa radial loads ntawm lawv tus kheej. Angular contact bearings tuaj yeem pab txhawb nqa kev thauj khoom hauv ob qho tib si thaum siv ntsej muag lossis rov qab-rau-rov qab.
