1.Kev faib tawm raws li kev coj ua ntawm kev thauj khoom

Spherical bearings tuaj yeem muab faib ua pawg hauv qab no raws li cov kev taw qhia ntawm lawv cov load lossis nominal hu lub kaum sab xis:

a) Radial bearings:Nws tsuas yog bears radial load, thiab lub nominal hu lub kaum sab xis yog nruab nrab ntawm 0 ° ≤τ≤30 °, uas yog tshwj xeeb muab faib mus rau hauv: Radial hu spherical bearing: nominal hu lub kaum sab xis τ = 0 °, haum rau bearing radial load thiab me me axial load. Angular contact radial spherical bearing: nominal contact angle 0° <τ≤30°, haum rau kev sib xyaw ua ke nrog radial thiab axial loads tib lub sijhawm.

b) Thrust bearings:Nws tsuas yog dais axial load, thiab lub nominal hu lub kaum sab xis yog nruab nrab ntawm 30 ° <τ≤90 °, uas yog tshwj xeeb muab faib ua: Axial hu thrust spherical bearing: nominal hu lub kaum sab xis τ = 90 °, haum rau axial load nyob rau hauv ib qho kev taw qhia. hu rau thrust spherical bearings: nominal hu cov ces kaum ntawm 30 ° <τ< 90 °, haum rau mas bearing axial loads, tab sis kuj muaj peev xwm dais ua ke loads.

2. Kev faib tawm raws li cov qauv ntawm lub nplhaib sab nraud

Raws li qhov sib txawv ntawm lub nplhaib sab nrauv, kheej kheej bearings tuaj yeem muab faib ua:

Integral txheej nplhaib spherical bearings

Ib leeg-slit txheej nplhaib spherical bearings

Muab ob npaug rau-seam txheej nplhaib spherical bearings

Muab ob npaug rau ib nrab txheej nplhaib kheej kheej bearings

3. Kev faib tawm raws li seb tus pas nrig kawg lub cev txuas nrog

Nyob ntawm seb tus pas nrig kawg lub cev txuas nrog, kheej kheej bearings tuaj yeem muab faib ua:

General spherical bearings

Qws kawg bearings

Ntawm lawv, tus pas nrig kawg kheej kheej bearing tuaj yeem raug cais ntxiv raws li cov khoom siv uas haum nrog tus pas nrig kawg lub cev thiab cov yam ntxwv kev sib txuas ntawm tus pas nrig kawg shank:

Nws txawv nyob ntawm qhov uas sib koom nrog tus pas nrig kawg lub cev

Assembled pas nrig kawg bearings: pas nrig xaus nrog cylindrical bore pas nrig kawg qhov muag, nrog radial kheej kheej bearings nrog los yog tsis muaj bolt rods nyob rau hauv lub bore.

Integral rod end bearings: pas nrig xaus nrog spherical bore pas nrig kawg qhov muag, bore nrog bearing puab rings nrog los yog tsis muaj bolt rods.

Pob Bolt Qws Kawg Spherical Bearing: Qws kawg nrog lub taub hau lub rooj zaum haum nrog pob taub hau bolts.

Raws li kev sib txuas yam ntxwv ntawm tus pas nrig kawg shank

Internally threaded pas nrig kawg spherical bearings: Lub pas nrig kawg shank yog ib tug internally threaded ncaj pas nrig.

Externally threaded pas nrig kawg spherical bearings: Lub pas nrig kawg shank yog ib tug externally threaded ncaj pas nrig.

Spherical bearings nrog welded lub rooj zaum pas nrig kawg: tus pas nrig kawg shank yog lub rooj zaum flanged, lub rooj zaum square lossis lub rooj zaum cylindrical nrog dowel pins, uas yog welded mus rau qhov kawg ntawm tus pas nrig.

Lub rooj zaum pas nrig kawg bearings nrog lub qhov ncauj xauv: pas nrig kawg shank yog sab hauv thiab nruab nrog lub ntsuas phoo.

4. Categorized los ntawm seb puas yuav tsum tau relubrication thiab tu

Spherical bearings tuaj yeem muab faib ua ob hom raws li seb lawv yuav tsum tau relubricated thiab khaws cia thaum ua haujlwm:

Txhim kho lubricated spherical bearings

Kev tu-dawb, nws tus kheej-lubricating kheej kheej bearings

5.Kev faib tawm raws li cov khoom siv sib txhuam ntawm qhov zawv zawg

Raws li kev sib xyaw ua ke ntawm kev sib txhuam cov ntaub ntawv ntawm zawv zawg nto, kheej kheej bearings tuaj yeem muab faib ua:

Hlau / steel kheej kheej bearings

Hlau / tooj liab alloy spherical bearings

Hlau / PTFE puas spherical bearings

Hlau / PTFE ntaub spherical bearings

Hlau / reinforced yas kheej kheej bearings

Hlau / zinc-raws li alloy spherical bearings

6. Categorized los ntawm qhov loj me thiab kam rau ua

Spherical bearings tuaj yeem muab faib ua cov hauv qab no raws li chav nyob ntawm qhov sawv cev ntawm qhov loj thiab qhov kam rau ua:

Metric spherical bearings

Ntiv kheej kheej bearings

7. Kev faib tawm los ntawm cov ntsiab lus dav

Raws li cov kev taw qhia ntawm load, nominal hu lub kaum sab xis thiab cov yam ntxwv hom, kheej kheej bearings yuav tsum comprehensively muab faib ua:

Radial kheej kheej bearings

Angular contact spherical bearings

Thrust spherical bearings

Qws kawg bearings

8. Kev faib tawm los ntawm cov qauv tsim

Spherical bearings tseem tuaj yeem muab faib ua ntau hom raws li lawv cov qauv tsim (xws li cov qauv tsis muaj cov khoom sib khi, lubrication zawj thiab lub qhov lubrication, cov qauv ntawm lubricant tis zawj, tus naj npawb ntawm lub nplhaib xauv grooves thiab xov rotation kev taw qhia ntawm lub pas nrig kawg lub cev, thiab lwm yam).
