Cov kabmob muaj cov nplhaib sab hauv thiab sab nraud, cov khoom dov (pob, cov menyuam lossis cov koob) thiab cov khoom tuav.Tsuas yog cov khoom khaws cia, cov seem muaj cov kabmob steel.Thaum cov kabmob ua haujlwm, cov kabmob, lub nplhaib sab nraud thiab cov kabmob dov lub cev yog raug rau siab zaus thiab kev ntxhov siab sib txawv.Cov kev ua haujlwm ntawm cov bearings yog qhov nyuaj heev.Lub load concentrates ntawm ib cheeb tsam me me ntawm lub cev dov.Txoj kev xav, rau lub pob, nws ua rau ntawm ib qho chaw;rau cov menyuam, nws ua rau ntawm ib txoj kab, thiab qhov chaw sib cuag ntawm lub dov lub caij thiab lub ferrule kuj yog me me (point / kab sib cuag), yog li thaum lub bearing qhov chaw ua hauj lwm, qhov chaw ntawm lub dov lub caij thiab lub ferrule yog raug rau lub siab loj, feem ntau mus txog 1500-5000 N / mm2;Thaum cov kabmob tig, nws kuj yuav tsum tau tiv thaiv lub zog centrifugal, thiab lub zog nce nrog qhov nce ntawm kev sib hloov ceev;Cov ntsiab lus dov thiab lub tes tsho Tsis tsuas yog dov tab sis kuj zawv zawg ntawm cov nplhaib, yog li muaj kev sib txhuam ntawm cov khoom dov thiab cov ferrule.Raws li kev sib koom ua ke ntawm ob peb lub zog saum toj no, qhov qaug zog tawg yog thawj zaug ntawm qhov chaw ntawm lub ferrule los yog lub cev dov nrog lub zog qaug zog tsawg, thiab thaum kawg lub qaug zog tev yog tsim, kom cov kabmob cuam tshuam cov nyhuv poob.Cov kev puas tsuaj ib txwm ntawm cov kabmob yog hu rau kev qaug zog puas tsuaj, thiab cov yas deformation, indentation, hnav, tawg, thiab lwm yam.

Cov kabmob lub neej thiab kev ntseeg tau muaj feem xyuam rau cov kabmob tsim, kev tsim khoom, lubrication tej yam kev mob, installation, txij nkawm thiab lwm yam, tab sis qhov zoo thiab kev ntseeg siab ntawm bearing cov ntaub ntawv yog qhov tseem ceeb.Rolling bearing qhov chaw ua haujlwm nyob rau hauv high-speed thiab ntev lub sij hawm nyob rau hauv lub complex kev nyuaj siab xws li tensile, compressive, dabtsi yog khoov, shearing, alternating, thiab high stress values.Yog li ntawd, cov kev cai rau dov bearings yog:

1) siab tsis kam rau cov yas deformation,

2) siab tiv thaiv kev sib txhuam thiab hnav cov khoom,

3) High rotation precision thiab dimensional precision,

4) zoo dimension stability,

5) Lub neej ua haujlwm ntev thiab kev ntseeg siab.

Rau cov bearings kev khiav hauj lwm nyob rau hauv tshwj xeeb tej yam kev mob, muaj tshwj xeeb yuav tsum tau xws li kub tsis kam, tsis kub tsis kam, corrosion kuj thiab diamagnetic kuj, thiab lwm yam.
