Yuav ua li cas paub qhov tseeb ntawm bearings?
Qhov tseeb ntawm bearings tuaj yeem paub qhov txawv ntawm cov hauv qab no:
1. Kev txheeb xyuas qhov tseeb
Bearings feem ntau yog cim nrog cov qhab nia raug, xws li P{{0}}, P6, P5, P4, P2, thiab lwm yam. Cov cim no sawv cev rau qib raug ntawm cov kabmob, cov P0 yog qhov tseeb, thiab lwm qib yog qib precision, thiab cov qib nce nyob rau hauv ib ntus. Los ntawm kev saib ntawm cov kabmob, koj tuaj yeem tau txais kev nkag siab ua ntej ntawm cov kabmob qhov raug.
2. Dimensional raug
Dimensional raug yog ib feem tseem ceeb ntawm bearing raug. Nws muaj feem xyuam rau ntau qhov sib txawv ntawm cov kabmob thaum lub sijhawm sib dhos, xws li qhov sib txawv ntawm qhov sib txawv ntawm lub puab lub cheeb, sab hauv txoj kab uas hla, qhov dav thiab sib dhos dav, thiab qhov tso cai sab hauv thiab sab nraud ntawm cov menyuam txheej. Deviation, tso cai txwv tus nqi ntawm chamfer loj, thiab tso cai variation nyob rau hauv dav, thiab lwm yam. Bearing khoom nrog high precision theem yuav tsum me me dimensional deviation qhov tseem ceeb. Yog li ntawd, koj tuaj yeem txiav txim siab seb qhov tseeb qhov tseeb ntawm cov kabmob ua tau raws li qhov yuav tsum tau ua los ntawm kev ntsuas qhov loj ntawm cov kabmob thiab muab piv rau qhov kam rau ua.
3. Kev sib hloov raug
Kev sib hloov qhov tseeb yog qhov kev ua tau zoo ntawm cov kabmob thaum lub sijhawm ua haujlwm, suav nrog kev tso cai radial runout thiab axial runout ntawm sab hauv thiab sab nraud, qhov tso cai rau sab nraud ntawm lub nplhaib sab hauv, qhov kev sib txawv ntawm qhov inclination ntawm txoj kab uas hla sab nraud, thiab thrust bearing raceway. Tso cai variation nyob rau hauv thickness, thiab lwm yam. Bearing khoom nrog high precision theem muaj stricter yuav tsum nyob rau hauv cov nqe lus ntawm kev sib hloov raug. Yog li ntawd, qhov tseeb theem ntawm cov kabmob tuaj yeem paub qhov txawv los ntawm kev sim nws qhov kev sib hloov qhov tseeb.
4. Cov tsos zoo
Cov tsos zoo ntawm cov kabmob kuj yog ib qho tseem ceeb hauv kev txiav txim siab nws qhov tseeb. Qhov saum npoo ntawm cov kabmob zoo yuav tsum yog du, tsis muaj pitting, xeb, tawg thiab lwm yam tsis xws luag. Nyob rau tib lub sijhawm, lub chamfering ntawm cov kabmob yuav tsum sib npaug thiab lub ntsej muag kawg yuav tsum tiaj tus. Yog tias pom muaj teeb meem zoo nyob rau ntawm cov kabmob, qhov tseeb ntawm cov kabmob yuav tsis mus txog tus qauv.
5. Cov qauv siv
Ntau lub teb chaws thiab cheeb tsam yuav xa mus rau cov qauv sib txawv los ntsuas qhov tseeb ntawm cov kabmob, xws li cov qauv ISO, JIS B 1514 cov qauv, German DIN cov qauv, thiab lwm yam. Yog li ntawd, thaum paub qhov txawv cov kabmob raug, nws tseem yuav tsum nkag siab thiab xa mus rau cov qauv sib xws. .
Qhov tseeb ntawm qhov sib txawv ntawm cov bearings tuaj yeem txiav txim siab los ntawm ntau yam xws li kev txheeb xyuas qib raug, qhov tseeb qhov tseeb, kev sib hloov qhov tseeb, qhov zoo ntawm qhov zoo thiab cov qauv siv. Nyob rau hauv kev siv tswv yim, tsim nyog precision qib bearings tuaj yeem xaiv raws li cov kev xav tau tshwj xeeb los xyuas kom meej qhov kev ua haujlwm zoo thiab kev ua haujlwm ntawm cov cuab yeej siv tshuab.
