Nta ● Lub pob ntawm angular contact ball bearing thiab raceway ntawm lub nplhaib puab thiab lub nplhaib sab nraud tuaj yeem tiv tauj ntawm lub kaum sab xis ntawm cov kev taw qhia radial.Thaum siv ib leeg, axial load yog txwv rau ib qho kev taw qhia, thiab nws tsim nyog rau kev sib xyaw ua ke ntawm axial load thiab radial load.● Vim tias cov kabmob no muaj lub kaum sab xis sib cuag, ib qho axial force tivthaiv yog tsim thaum radial load ua.Yog li ntawd, nws yog feem ntau siv nyob rau hauv daim ntawv ntawm symmetry los yog khub ntawm ob sab ntawm lub ncej.● Tseem muaj hom siv cov khoom siv ceramic.Lub kaum sab xis muaj ob hom kev sib cuag, 15 ° thiab 25 °.15 ° yog siv rau kev siv ceev ceev.25 ° yog haum rau lub sijhawm uas yuav tsum tau axial rigidity.Lub tawb yog ua los ntawm polyamide raws li tus qauv.Thov siv lub tawb polyamide hauv qab 120 °.Dimensional raug thiab rotational raug raws li JIS chav kawm 5 lossis 4. Thov xa mus rau nplooj 7. Preload ● Teem 4 hom qauv preload npaum li cas.Xaiv qhov xav tau preload raws li cov txheej txheem xaiv hauv lub rooj ntawm sab xis.● Xa mus rau nplooj ntawv 16 txog 18 rau tus qauv preload tus nqi rau txhua series thiab loj.

Kev sib dhos Rau kev siv ntau lub rooj sib dhos, thov xa mus rau nplooj ntawv 12 txog 13. Ceramic pob hom Yuav kom txo tau lub centrifugal quab yuam ntawm lub pob thaum lub sij hawm kev kub ceev, ib lub pob ceramic uas muaj qhov tsawg dua cov kabmob steel yog siv.● Saib cov lus hauv qab no rau ntau yam khoom ntawm ceramics thiab bearing steels.● Ntxiv "SH6-" thaum pib ntawm tus qauv naj npawb ntawm cov kabmob siv cov khoom siv ceramic.● Lub preload thiab axial rigidity yog kwv yees li 1.2 npaug ntawm cov kabmob steel pob.Preload cim xaiv tus qauv E (micro preload) Tiv thaiv cov neeg kho tshuab kev co thiab txhim kho qhov tseeb L (lub teeb preload) Kev kub ceev (dmn tus nqi ntawm 500,000) tseem muaj qee yam rigidity M (nruab nrab preload) Cov tiam yog sib dua li tus qauv ceev Rigidity H nrog siab dua preload (hnyav preload) ua rau siab tshaj plaws rigidity ntawm tsawg ceev.
