Nyob rau hauv lub neej niaj hnub no, angular contact pob bearings muaj ntau yam thiab xav tau cov kabmob hauv ntau lub teb, thaum angular hu npas kabmob muaj ntau xim sib txawv dua li lwm hom bearings! Feem ntau, cov khoom thauj axial uas ib leej ntawm cov kab sib txuas ntawm lub kaum ntse ntse lub pob tuaj yeem txais yuav tsuas yog lub thauj khoom ntawm ib qho kev taw qhia xwb, thiab tsuas yog txwv txoj haujlwm axial hloov kev nyuaj siab ntawm cov kabmob plhaub thiab cov ncej muaj tib qho kev taw qhia. Yog hais tias khub ntawm cov kabmob tau nruab, tus kabmob tau tsim. Lub nplhaib sab nraud yog qhov txawv txav kom nws tiv thaiv qhov tshwm sim ntawm cov khoom ntxiv axial rau ntawm cov hlau lub tog raj kheej. Angular cuag pob bearings tseem tau muab faib ua ntau hom, sib cais, tsis sib cais, paired angular contact bearings thiab ob chav kab lub kaum pob hu rau pob bearings, thiab cov sub-bearings no sib txawv. Thaum peb siv nws, peb yuav tsum nkag siab nws los ntawm cov hmoov kom paub meej tias lub tshuab tuaj yeem khiav tau zoo tom qab kev teeb tsa.
Cov caij sib dhos ntawm lub npov hu rau lub pob lub kaum pob yog lub pob vim tias nws yog hom sib kis (sib txawv ntawm cov kab sib txuas ntawm cov menyuam cov menyuam), yog li nws tuaj yeem muab cov kev sib hloov ntau dua, qhov muaj peev xwm kub me dua thiab ntau dua kev sib hloov ceev. Nyob rau hauv cov ntaub ntawv ntawm ultra-high-speed spindle daim ntawv thov, hybrid bearings nrog ceramic pob kuj tseem siv. Piv nrog cov tsoos steel pob, cov pob zeb cov khoom siv pob khoom nws tus kheej muab cov nplais npas pob kabmob muaj qhov txhav siab, lub nrawm nrawm, qhov kub tsis kam thiab lub neej ntev, yog li ua tau raws li cov neeg siv khoom xav tau cov cuab yeej siv cav cov khoom lag luam.
Nyob rau hauv cov ntsiab lus ntawm lub kaum sib tiv tauj ntawm lub kaum ntse ntse hu rau lub pob bearings, tam sim no nrov cov ces kaum ntawm 15 thiab 25 degrees; feem ntau hu rau lub kaum sab xis ntawm 15 degrees muaj qhov ua haujlwm ntawm kev sib hloov ceev, thaum sib tiv tauj lub kaum sab xis ntawm 25 degrees muaj qhov siab axial load nqa lub peev xwm. Vim tias qhov kev xaiv thau khoom tau muaj qhov cuam tshuam zoo rau daim ntawv thov ntawm precision angular hu rau pob bearings, xws li lub nra hnyav thiab cov nqi siab, qhov nruab nrab lossis hnyav hnyav preloading yog nyiam; rau kev kub ceev thiab siab precision daim ntawv thov, Hauv kev xaiv thaum ntxov ntawm cov kabmob txawv teb, nws yog qhov tsim nyog yuav tsum tau them sai sai rau kev xaiv ntawm qhov tsim nyog preload. Lub preload tau muab faib ua peb hom: teeb, nruab nrab thiab hnyav. Lub teeb preload yog ntau dua. Txhawm rau kom yooj yim rau kev siv cov qhua tuaj noj mov, yuav muaj ib khub ntawm cov sib tw angular hu rau pob bearings. Hom kabmob txawv teb no tshem tawm ntawm cov neeg siv khoom txoj haujlwm preload, uas txuag lub sijhawm ua haujlwm.
