Qhov zoo ntawm rab koob bearings: koob rau cov menyuam bearings yog nruab nrog nyias thiab ntev rollers (qhov ntev ntawm cov chais yog 3 mus rau 10 npaug ntawm txoj kab uas hla, thiab txoj kab uas hla feem ntau tsis ntau tshaj 5 hli), yog li cov qauv radial yog compact. Thaum nws txoj kab uas hla sab hauv thiab lub peev xwm thauj khoom zoo ib yam li lwm hom bearings, lub taub sab nraud yog qhov tsawg tshaj plaws, uas yog tshwj xeeb tshaj yog haum rau kev txhawb nqa cov qauv nrog txwv radial installation qhov ntev. Koob cov menyuam bearings yuav tsum tau ua ke nrog lub nplhaib bearing thiab daim ntawv thov raws li lub sijhawm sib txawv, qhov tseeb ntawm machining thiab nto zoo. Koob cov menyuam bearings yog cov kabmob uas ua ke nrog radial koob rau cov menyuam bearings thiab cov kabmob thrust bearings.

Qhov sib txawv ntawm rab koob rau cov menyuam bearings:
1. Kev sib txhuam coefficient ntawm dov bearings yog me dua li cov zawv zawg bearings, thiab kev sib kis tau zoo. Feem ntau, kev sib txhuam coefficient ntawm zawv zawg bearings yog 0.08-0.12, thaum qhov sib txhuam coefficient ntawm rolling bearings tsuas yog 0.001-0.005;
2. Rolling bearings tau standardized, serialized thiab generalized, haum rau loj ntau lawm thiab muab khoom, thiab yog heev yooj yim mus use thiab tswj;
3. Rolling bearings yog ua los ntawm cov kabmob steel thiab tau txais kev kho cua sov. Yog li ntawd, dov bearings tsis tsuas yog muaj cov cuab yeej siv siab thiab lub neej ua haujlwm ntev, tab sis kuj tseem txuag tau cov hlau tsis muaj hlau uas kim dua siv hauv kev tsim cov zawv zawg bearings;
4. Lub hauv paus clearance ntawm dov bearing yog heev me me, thiab lub machining raug ntawm txhua qhov yog siab, yog li cov neeg khiav hauj lwm yog siab. Nyob rau tib lub sijhawm, qhov rigidity ntawm cov kabmob tuaj yeem nce ntxiv los ntawm kev thauj khoom ua ntej. Qhov no tseem ceeb heev rau precision machinery;
5. Qee cov kabmob dov tuaj yeem dais radial load thiab axial load tib lub sijhawm, yog li ntawd, cov qauv ntawm cov kabmob txhawb nqa tuaj yeem yooj yim;
6. Vim muaj kev sib kis tau zoo thiab tsis tshua muaj hluav taws xob tsim ntawm dov bearings, kev noj cov roj lubricating tuaj yeem txo qis, thiab lubrication thiab tu yooj yim dua;
7. Rolling bearings tuaj yeem siv tau yooj yim rau txhua qhov axis hauv qhov chaw.
Rolling bearings feem ntau yog tsim los ntawm plaub ntu: lub nplhaib sab nraud, lub nplhaib puab, dov lub cev thiab lub tawb. Hais lus nruj me ntsis, nws yog tsim los ntawm rau qhov chaw: lub nplhaib sab nraud, lub nplhaib puab, dov lub cev, tawb, foob thiab lubricating roj. Tsuas yog muab tso, tsuav yog nws muaj lub nplhaib sab nraud, lub nplhaib sab hauv, thiab cov ntsiab lus dov, nws tuaj yeem txhais tau tias yog cov kabmob dov. Raws li cov duab ntawm cov khoom dov, dov bearings tau muab faib ua ob pawg: pob bearings thiab cov menyuam bearings. Bearings uas nws cov ntsiab lus dov yog rab koob rollers yog rab koob rau cov menyuam bearings. Cov kabmob uas nws cov ntsiab lus dov yog pob yog pob bearing lossis pob bearing.
