Vim li cas cov pob bearings zoo dua li cov menyuam bearings?

Bearings yog cov khoom tseem ceeb ntawm ntau lub tshuab thiab cov cuab yeej siv vim tias lawv txo kev sib txhuam thiab ua kom muaj zog ntawm kev sib hloov thiab rov ua haujlwm. Muaj ob pawg loj ntawm cov kabmob: pob bearings thiab cov menyuam bearings. Lawv tuaj nyob rau hauv cov duab sib txawv, qhov ntau thiab tsawg thiab cov khoom, haum rau kev siv sib txawv.

Pob bearings siv nws tus kheej-aligning npas li dov cov ntsiab lus, thaum cov menyuam bearings siv cylindrical, conical los yog spherical rollers. Qhov sib txawv tseem ceeb ntawm lawv yog qhov chaw sib cuag ntawm cov khoom dov thiab cov nplhaib. Pob bearings yog qhov taw tes sib cuag, uas txhais tau hais tias qhov chaw sib cuag me me heev. Cov menyuam bearings muaj kab sib cuag, uas txhais tau hais tias qhov chaw sib cuag yog loj.

Qhov chaw tiv tauj cuam tshuam rau kev ua haujlwm thiab kev ua haujlwm zoo. Pob bearings muaj kev sib txhuam qis thiab ua haujlwm, uas txhais tau tias lawv tuaj yeem ua haujlwm ntawm qhov nrawm dua thiab qis dua. Cov menyuam bearings muaj peev xwm ua haujlwm siab dua thiab kev poob siab, uas txhais tau hais tias lawv tuaj yeem tiv taus qhov hnyav thiab hnyav dua.

Yog li ntawd, pob bearings yog superior rau cov menyuam bearings nyob rau hauv tej yam, xws li:

• Ceev: Pob bearings tuaj yeem ua tiav qhov kev sib hloov ceev dua li cov menyuam bearings vim lawv muaj kev sib txhuam tsawg thiab inertia.

• Suab nrov: Pob bearings tsim suab nrov thiab kev vibration dua li cov menyuam bearings vim tias lawv txav tau yooj yim dua thiab meej dua.

• Nyhav: Pob bearings yog sib dua li cov menyuam bearings vim hais tias pob bearings muaj tsawg dua thiab me me dov ntsiab.

• Nqi: Pob bearings tsis tshua kim dua cov menyuam bearings vim lawv tsim thiab tsim khoom yog yooj yim dua thiab ntau tus qauv.

Txawm li cas los xij, pob bearings tsis yog ib txwm zoo dua li cov menyuam bearings. Cov menyuam bearings muaj lawv tus kheej zoo, xws li:

• Chaw thau khoom: Cov menyuam bearings tuaj yeem ua haujlwm ntau dua radial thiab axial loads dua li pob bearings vim tias lawv muaj thaj tsam loj dua thiab kev thauj khoom zoo dua.

• Kev nruj: Cov menyuam bearings muaj zog thiab ruaj khov dua li pob bearings vim lawv deform thiab deflect tsawg dua nyob rau hauv load.

• Alignment: Cov menyuam bearings tuaj yeem ua kom haum rau qee qhov tsis zoo thiab deflection ntawm lub ncej thiab vaj tse vim tias lawv muaj qhov sib txawv ntawm tus kheej.

Hauv cov ntsiab lus, cov pob bearings thiab cov menyuam bearings muaj qhov zoo sib txawv thiab qhov tsis zoo, thiab kev xaiv ntawm cov kabmob yog nyob ntawm cov kev cai tshwj xeeb thiab cov xwm txheej ntawm daim ntawv thov.
