Pom kev

Bearings yog indispensable cov ntsiab lus tseem ceeb hauv kev siv tshuab engineering. Lawv lub luag haujlwm tseem ceeb yog kom txo cov kev txhuamricicient ntawm kev sib hloov ntawm cov tshuab, txhawb cov tshuab ua haujlwm ntawm lawv, thiab ua haujlwm ruaj khov ntawm cov khoom siv hauv tshuab. Los ntawm cov cuab yeej siv hauv yim txhua hnub, thiab los ntawm tsheb thiab siab}- Kev tsheb ciav hlau siab, bearings} Ceev rau peb txhua tus neeg kho mob cov xwm txheej pom zoo. Cov hauv qab no yog cov ncauj lus kom ntxaws ntxiv kev faib tawm, cov tsis sib haum, daim ntawv thov kev xaiv, thiab txij nkawm:

I. Cov kev faib tawm tseem ceeb ntawm bearings

Raws li kev sib txhuam cov khoom siv thiab cov yam ntxwv ua, cov kabmob tau muab faib ua ob pawg loj: cov kabmob bearings thiab zawv zawg bearings. Ntawm lawv, dov bearings tau dhau los ua cov ntsiab lus vim lawv qhov kev sib txhuam qis dua thiab muaj txiaj ntsig zoo, thaum cov zawv zawg bearings excel hauv cov xwm txheej tshwj xeeb.

(I) dov bearings

Dov bearings hloov kev sib txhuam ntawm tus ncej thiab cov kabmob vaj tsev nyob rau hauv rolling ntsiab los ntawm cov khoom siv hlau thiab chais). Lawv muaj qhov tsis tshua muaj kev sib txhuam cov coefficient (feem ntau 0.001-0.005) thiab muaj efficiency. Lawv tuaj yeem yog cov kev faib tawm ntxiv raws li cov duab thiab qauv ntawm Roll hais:

Sib Sib Zog Groove Pob Bearings

Lub tsev: Muaj lub nplhaib sab hauv, ntiv nplhaib sab nraud, cov pob hlau, thiab lub tawb. Nws tuaj yeem tiv thaiv radial loads thiab cov roj muaj axial me me.

Nta: Cov qauv yooj yim, tus nqi qis, thiab kev tig ceev ceev (haum rau 10,000-30,000 rpm). Nws yog qhov dav tshaj plaws siv hom kabmob.

Cov Ntawv Thov: Motors, cov twj tso kua dej, cov khoom siv tsheb tsheb tsheb, piv txwv, tshuab ntxhua khaub ncaws, cua txias compressors).

Cylindrical Cov Menyuam Bearings

Lub tsev: Rolling ntsiab yog cylindical rollers. Lub puab lossis sab nraud ntiv nplhaib tuaj yeem sib cais, thiab lawv muaj zog radial load {{1-3 zaug ntau dua li sib sib zog nqus cov pob zig muag pob:.

Nta: Haum rau high - thau khoom thiab siab- ceev scenarios tab sis tsis tuaj yeem tiv thaiv axial thauj.

Cov Ntawv Thov: Cov cuab yeej ntxaiv, tsheb tsheb cable, cov motors loj.

Tapered Cov Menyuam Bearings

Lub tsev: Rolling ntsiab yog tapered chais, nrog sab hauv thiab sab hauv rings featuring conical ragerurays. Lawv tuaj yeem tiv thaiv ob qho tib si radial thiab axial loads ib txhij.

Nta: Cov thauj khoom siab - nqa muaj peev xwm; Kev tshem tawm tuaj yeem hloov kho thaum lub sijhawm teeb tsa, tab sis tig ceev yog qis dua me ntsis uas ntawm kev sib sib zog nqus groove pob bearings.

Cov Ntawv Thov: Tsheb sib txawv, cov log reducers, kis cov tshuab ntawm cov tshuab hnyav.

Cov Bearings Bearings

Lub tsev: Rolling ntsiab yog pob lossis yob, tsim qauv kom tiv thaiv Axial loads (Unidirectional) nrog lub zog radial thauj khoom muaj peev xwm.

Subtypes: Thrust pob bearings (haum rau lub teeb thauj thiab kev kub ceev) thiab thawb cov menyuam bearings (haum rau cov khoom siv hnyav thiab qis nrawm).

Cov Ntawv Thov: Crane hooks, kev txhawb nqa axial rau kev siv lub tshuab cuab ntxaiv, tsheb pob.

Tus kheej -} cov kabmob

Lub tsev: Lub nplhaib sib tw sab nraud yog spherical, uas tuaj yeem them rov qab rau cov kev sib cav sib ceg (pub rau ± 2℃-3℃deflection).

Nta: Kev cuam tshuam zoo tsis kam, haum rau cov xwm txheej uas cov shafts yog tus nquag rau tilting.

Cov Ntawv Thov: Cov tshuab ua liaj ua teb, tshuab xaws textile, papermaking cov khoom siv.

(II) Zawv zawg Bearings

Zawv zawg bearings tau ua haujlwm raws li kev sib txhuam zawv zawg thiab muaj cov qauv yooj yim (feem ntau yog siv cov kab mob hauv tsev thiab cov kabmob sib tw). Lawv muab cov thawv siab heev - nqa tau muaj peev xwm thiab tsim nyog} ceev} Kev ceev ceev, lossis compact {{letch qauv scenarios:

Hlau zawv zawg bearings: Xws li Babbitt alloy bearings (hnav {{free} tiv taus, siv nyob rau hauv chav turnings nruab nrab- ceev machinery).

Tsis - Cov pob tsuas zawv zawg bearings: Xws li yas bearings (corrosion - tiv taus thiab graphite bearings) thiab graphite bearings (siab - rurnaces).
