Radial bearings, radial bearings, yog siv rau radial bearings thiab muaj ib lub npe nominal nyob rau ntau ntawm 0 ° txog 45 ° . Radial pob bearings yog tsuas yog cais dej num rau hauv ob hom nram qab no:
1. Radial tiv thaiv bearings - Centripetal bearings nrog ib tug nominal hu lub kaum sab xis ntawm 0 ° .
2. Cov lus sib txuas lus radial bearings - radial bearings nrog ib lub npe sib npaug ntawm 0 ° txog 45 ° .
Radial kabmob
Dab tsi yog cov ntaub ntawv qhia txog kev coj?
Raws li cov txheej txheem tseem ceeb ntawm txoj kev muaj peev xwm ua haujlwm, cov khoom siv cov khoom yuav tsum muaj qee qhov muaj peev xwm, kos duab, thermal conductivity, sib txhuam coefficient, tus duav nplaum, coj los tiv thaiv, qaug zog thiab tiv thaiv kev kub ntxhov. Tsis muaj cov ntaub ntawv ua tiav tag nrho cov kev cai. Qhov no yog vim li cas cov eclectic txoj kev siv feem ntau yog siv rau feem tsim. Cov hauv qab no piav qhia txog cov khoom thiab cov ntaub ntawv ntawm cov khoom siv cov khoom siv:
Nqa cov hlau
Cov kabmob (Cov Phaw) yog siv dav. Lawv feem ntau ntawm ob hom: tin-based bearing alloys thiab lead-based bearing alloys, uas muaj cov yam ntxwv ntawm kev khiav ceev thiab hauv cov pob zeb yooj yim. Lawv feem ntau siv raws li cov kabmob bushings txuas nrog steel bearing ncoo bases. Cov kabmob sib txawv ntawm cov kabmob yog tsimnyog thiab muaj kev tswj tuskheej rau kev sib tw me me lossis cov khoom ntiag tug. Vim tias cov hmoov av lossis txawv teb chaws tuaj yeem nkag tau rau lub roj nplaum ntawm qhov khoom siv no thiab tiv thaiv lub hau tsis zoo, hom kev embedment ua rau lawv cov khoom zoo heev. Cov khoom siv hauv phau ntawv journal yuav ua tau me ntsis hlau, tawv steel, lossis cam khwb cia hlau.
bronze
Bronze bearings yog tsim rau cov ntawv sau npe uas txawb thiab bearings yog nruab nrab thiab thaum tsis ceev thiab hnyav hnyav. Lawv tuaj yeem tsim los ntawm ntau hom kev sib ncos mus ua kom tau ntau yam sib txawv ntawm lub cev.
Tooj liab
Hom kabmob no muaj peev xwm muaj peev xwm tshaj li qhov kev coj noj coj ua thiab tsis yoojyim, thiab yog li ntawd siv rau hauv cov ntawv sau qhov chaw ntawm lub qhov rooj tsis sib haum thiab nruab nrab.
cam khwb cia hlau:
Cov khoom siv hlau casting cov ntaub ntawv yog siv dav siv tsawg dua daim ntawv thov. Lub zog ntawm phau ntawv ceev xwm txheej yuav tsum siab tshaj qhov nyuaj ntawm txoj kev coj. Qhov chaw ua haujlwm yuav tsum ua kom zoo zoo nrog graphite thiab roj sib tov. Nws yuav tsum tau muaj tias yuav tsum muaj qhov zoo ntawm nruab nrab ntawm phau ntawv journal thiab kev coj tus kheej.
Radial Bearing / Porous bearing
Ua ntej, cov hmoov hlau yog sintered thiab tom qab ntawd raus lub roj kom ua rau yus tus kheej "lubricating" lossis "porous" bearings. Bronze ntawm ntau lub compositions yog dav siv nyob rau hauv ntxim nyiam bearings, thiab tsawg dua hlau yog siv. Txij li thaum lub ntxeem tau lub cev muaj lub tshuab lubricating, nws yog tsuas yog siv thaum cov kabmob tsis yooj yim lossis tsis tau txais kev txhim kho lubrication thaum lub dav lubrication method siv.
Pa roj thiab yas
Pure carbon bearings muaj peev xwm ua tiav cov txiaj ntsim tau los ntawm kev kub ntxhov, los yog thaum siv lub cev tsis lubrication txoj kev siv tsis tau. Teflon yog ib lub hnab yas heev. Bearings los ntawm nws muaj ib co coefficient ntawm kev sib txhuam thiab siv nyob rau hauv cov roj-free daim ntawv uas lawv muaj peev xwm khiav lag luam nyob rau hauv qis qis los yog intermittently oscillating thiab nyob rau hauv cov mob hnyav. Cov kev ntsuam xyuas tau qhia tias qee cov kev sib txuas ntawm cov ntaub ntawv ua haujlwm zoo ua ke, thaum lwm tus tsis ua. Cov khoom sib txuas ua ke uas tsis ua hauj lwm zoo ua ke yuav muaj hnav ntev li.
