Cov yam ntxwv tseem ceeb ntawm Plaub-Point Hu rau Pob Bearings
Plaub-point sib cuag pob bearings yog ib tug subtype ntawm angular hu pob bearings. Lawv cov geometry tshwj xeeb tso cai rau lawv tswj cov radial, axial, thiab lub sijhawm thauj khoom ib txhij. Hauv qab no yog cov yam ntxwv tseem ceeb uas txhais tau plaub-point sib cuag pob bearings:
Hu rau Angle thiab Load Distribution
Plaub-point sib cuag pob bearings yog tus cwj pwm los ntawm kev sib cuag lub kaum sab xis ntawm kwv yees li 35 degree txog 45 degree.
Qhov geometry no ua rau cov kabmob ib txhij txhawb nqa axial thiab radial loads, faib cov rog sib npaug thoob plaws cov ntsiab lus sib cuag.
Ib Leeg Tsim
Tsis zoo li ob-kab angular contact bearings, plaub-point contact bearings siv ib kab tsim nrog ob lub nplhaib sab hauv raceways.
Qhov kev tsim no txo qhov dav dav ntawm cov kabmob thaum tuav lub peev xwm siab, ua rau nws zoo tagnrho rau kev siv qhov chaw txwv.
Split puab nplhaib
Lub nplhaib puab ntawm plaub-point tiv tauj bearings yog feem ntau faib ua ob halves.
Qhov kev sib cais tsim no yooj yim sib dhos thiab tso cai rau cov kabmob kom haum rau ob qho tib si thrust thiab radial rog zoo.
Siab tawv
Plaub-point tiv tauj bearings nthuav tawm cov txheej txheem siab nruj vim muaj ntau lub ntsiab lus sib cuag thiab lawv lub peev xwm los tuav lub sijhawm thauj khoom.
Qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas qhov tseeb qhov chaw thiab rigidity yog qhov tseem ceeb.
Khoom siv thiab Durability
Feem ntau ua los ntawm cov qib high-qib bearing steel lossis ceramic cov ntaub ntawv, cov bearings no muaj kev tiv thaiv zoo heev rau hnav thiab deformation.
Ntau tus qauv kuj tseem muaj cov txheej txheem tshwj xeeb lossis cov ntsaws ruaj ruaj los txhim kho kev tiv thaiv corrosion thiab ua haujlwm ntev.
Nkag siab txog Cov Qauv Tsim Qauv
Txhawm rau kom ntseeg tau qhov kev xaiv raug ntawm plaub-point sib cuag pob bearings, nws yog ib qho tseem ceeb kom nkag siab txog lawv cov qauv tsim. Cov neeg tsim khoom siv cov lej lej lej los txheeb xyuas qhov ntev, kam rau ua, thiab cov qauv tsim. Hauv qab no yog ib qho kev piav qhia ntawm kev txhais cov lej no:
Basic Designation
Cov cai yooj yim feem ntau pib nrog cov lej (piv txwv li, 718, QJ).
Piv txwv li, "QJ" qhia txog plaub-point sib cuag pob bearing nrog cais puab rings.
Inner thiab Outer Dimensions
Cov lej hauv qab no sawv cev rau txoj kab uas hla hauv millimeters. Piv txwv li, nyob rau hauv "QJ 208," "08" yog hais txog ib txoj kab uas hla ntawm 40 mm (raws li ib tug standardized bearing loj kab kos).
Suffix Codes
Cov tsiaj ntawv tom qab thiab cov lej qhia cov qauv tsim tshwj xeeb, xws li cov khoom siv tawb, tshem tawm, thiab kev sib khi.
Common suffixes muaj xws li:
C2, C3, C4: Internal clearance theem.
MAS, MB: Cov khoom siv tooj dag lossis steel tawb.
2RS, Z, ZOS: kaw los yog shielded tsim rau kev tiv thaiv ntxiv.
Preload thiab Precision Qib
High-precision daim ntaub ntawv feem ntau xav tau bearings nrog rau cov qib preload lossis raug, qhia los ntawm cov lej ntxiv xws li "P4" lossis "P5" (qhia txog qib ISO precision).
Kev nkag siab txog cov lej no tso cai rau cov engineers xaiv cov kabmob uas tsim nyog tshaj plaws rau lawv daim ntawv thov, ua kom zoo dua qub thiab ua haujlwm ntev.
