Bearing kev soj ntsuam zoo

lub teb chaws tus qauv
1. Lub teb chaws tus qauv rau kev vibration acceleration (feem ntau hu ua Z-standard)
Cov qauv no tau tsim ua ntej los ntsuas qhov kev vibration acceleration tus nqi ntawm cov bearings thaum lub sij hawm tig los txiav txim seb qhov zoo ntawm cov bearings. Nws muab faib ua peb theem zoo: Z1, Z2, thiab Z3, los ntawm qis mus rau siab. Tam sim no, domestic bearing manufacturers tseem siv cov kev vibration acceleration qhov tseem ceeb los ntsuas qhov zoo ntawm bearings, uas tsuas yog luv luv qhia txog lub neej qaug zog ntawm bearings.
2. Vibration speed standard (feem ntau hu ua V-standard)
Vim tias qhov tseem ceeb ntawm kev vibration acceleration tus qauv tseem tsis tau raug tshem tawm, cov qauv no tau tshwm sim raws li tus qauv tsim los ntawm Ministry of Machinery Industry, thiab tau tsim los ntawm European cov qauv ua ke nrog cov xwm txheej tiag tiag thiab kev xav tau ntawm Tuam Tshoj. Qib zoo ntawm cov kabmob yog txiav txim siab los ntawm kev kuaj xyuas qhov kev vibration ceev ntawm bearings (sib npaug rau cov qauv hauv tebchaws). Nws muab faib ua tsib theem: V, V1, V2, V3, thiab V4. Cov qib zoo ntawm ntau yam pob bearings muaj xws li V, V1, V2, V3, thiab V4; Qib zoo ntawm cov menyuam bearings (cylindrical thiab conical) muab faib ua plaub theem zoo los ntawm qis mus rau siab: V, V1, V2, thiab V3.
Nws qhia txog qhov zoo ntawm cov kabmob los ntawm kev kuaj xyuas qhov kev vibration thiab nrawm ntawm bearings nyob rau hauv ntau zaus bands (tsawg zaus, nruab nrab zaus, siab zaus). Nws muaj peev xwm txheeb xyuas seb puas muaj teeb meem geometric loj (xws li lub nplhaib steel ellipses), cov teeb meem zoo nrog kev sib tw / dov cov ntsiab lus, thiab cov teeb meem zoo nrog tawb hauv cov kabmob. Qhov no tau ua kom muaj kev vam meej zoo piv rau kev siv vibration acceleration los ntsuas cov kabmob zoo. Tam sim no, bearings xa tawm mus rau Tebchaws Europe hauv Suav teb, nrog rau peb cov tub rog thiab kev lag luam aerospace, txhua tus tau txais kev kuaj xyuas zoo raws li tus qauv no. Nyob rau tib lub sijhawm, kev ntsuam xyuas qhov zoo ntawm cov kabmob tuaj ntawm Tebchaws Europe thiab txheeb xyuas cov kabmob cuav tuaj yeem muab tau txhais tau tias.
Muaj ob qho qauv sib txuas rau kev kuaj xyuas cov kabmob zoo, thiab cov kabmob uas muaj qib siab ntawm "Z tus qauv" yuav tsis muaj qhov ua tau zoo thaum kuaj nrog "V tus qauv", thiab tsis muaj kev sib raug zoo ntawm ob. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev tshuaj xyuas zoo ntawm cov bearings.
