Lub Pob Bearing yog ruaj khov, lub zog poob me me, thiab kev ua tau zoo yog siab

Lub pob bearing yog ib hom dov bearing. Lub pob tau nruab rau hauv nruab nrab ntawm lub nplhaib sab hauv steel thiab lub nplhaib hlau sab nraud, uas tuaj yeem nqa tau lub nra loj. Kuj hu ua pob bearings.
Pob bearings feem ntau yog tsim los ntawm plaub yam tseem ceeb: pob, puab nplhaib, sab nrauv thiab tawb, tseem hu ua tawb lossis tuav. General muaj pob bearings ua tau raws li AISI 52100 tus qauv. Cov pob thiab cov nplhaib feem ntau yog ua los ntawm high-chromium steel, thiab Rockwell C-scale hardness yog hais txog 61-65. Lub hardness ntawm lub tawb yog qis dua lub pob thiab lub nplhaib, thiab nws cov khoom yog hlau (xws li: nruab nrab carbon steel, aluminium alloy) los yog non-hlau (xws li: Teflon, PTEF, polymer khoom). Pob bearings muaj kev sib txhuam kev sib txhuam tsawg dua li phau ntawv xov xwm bearings, yog li ntawm tib qhov ceev, qhov kub ntawm kev sib txhuam yuav qis dua.
Hauv kev tsim cov khoom siv tshuab, dov bearings thiab zawv zawg bearings feem ntau siv. Piv nrog rau zawv zawg bearings, dov bearings muaj qhov zoo thiab qhov tsis zoo hauv qab no.
(1) Hauv kev ua haujlwm dav dav, kev sib txhuam coefficient ntawm cov kabmob dov yog me me thiab yuav tsis hloov nrog kev hloov pauv ntawm kev sib txhuam coefficient, thiab yog qhov ruaj khov; qhov pib thiab khiav torque yog me me, lub zog poob yog me me, thiab cov efficiency siab.
(2) Lub radial clearance ntawm dov bearing yog me me, thiab tuaj yeem raug tshem tawm los ntawm axial preloading, yog li kev khiav haujlwm raug siab.
(3) Lub axial dav ntawm dov bearing yog me me, thiab qee cov bearings dais cov radial thiab axial loads tib lub sijhawm, nrog cov qauv compact thiab yooj yim ua ke.
(4) Rolling bearings yog cov qauv tsim nrog cov txheej txheem siab thiab tuaj yeem ua rau hauv cov khoom siv, yog li tus nqi qis.
