Cov menyuam bearings txawv ntawm pob bearings. Daim ntawv ntawm kev sib cuag yog kab sib cuag, uas txawv ntawm qhov taw tes sib cuag ntawm pob bearings. Yog li ntawd, kev sib hloov qhov tseeb ntawm cov menyuam ncej yog qhov nyuaj dua li cov pob bearings. Nov yog qee yam tseem ceeb txog dov bearing rotation raug.
1. Qhov cuam tshuam ntawm kev sib haum xeeb cov kauj ruam ntawm cov kabmob sib hloov raug
Hauv lub voj voog sab hauv, cov kauj ruam sib haum xeeb yog 10th thiab 42 - xaj. Lub nplhaib puab tig ntawm cov kabmob puab lub nplhaib yog tig rau ib lub lim tiam. Ntawm lawv, qhov amplitude ntawm qhov yuam kev roundness yog 0.010mm, qhov sib txawv radial yog 0.040mm, thiab tus naj npawb ntawm cov menyuam yog 10. Nws tuaj yeem pom tau tias raws li cov kauj ruam sib haum xeeb nce, qhov Lub voj voog ntawm lub nplhaib sab hauv radial beating txheej txheem txo qis, qhov radial beating huab point nce, thiab lub amplitude ntawm lub nplhaib puab -radial beating tus nqi yog txo qis, yog li nws tuaj yeem pom tias nws tuaj yeem pom kev sib haum xeeb muaj kev cuam tshuam ntau dua ntawm kev sib hloov. raug.
Qhov cuam tshuam ntawm cov kauj ruam sib haum xeeb ntawm qhov siab tshaj plaws radial ntaus nqi ntawm lub voj voog sab hauv, peb tuaj yeem pom tias raws li cov kauj ruam sib haum xeeb nce, qhov siab tshaj plaws radial beating tus nqi ntawm lub nplhaib puab hloov pauv raws sijhawm; Thaum tus naj npawb yog multiplied, qhov siab tshaj plaws radial ntaus nqi ntawm lub nplhaib puab yog tus nqi siab tshaj plaws; tus nqi siab tshaj plaws ntawm qhov siab tshaj plaws radial dhia tus nqi ntawm lub nplhaib puab qhia tau hais tias qhov kev poob qis nrog qhov nce ntawm qhov kev sib haum xeeb. Nws tuaj yeem pom tau tias qhov cuam tshuam ntawm kev txiav txim siab qis ntawm kev sib hloov qhov tseeb yog ntau dua, thiab qhov cuam tshuam ntawm high-end harmonics ntawm qhov tseeb yog tsawg dua. Qhov no yog vim cov txheej txheem ntawm qhov kev txiav txim siab qis qis qis, thiab nws qhov kev sib haum xeeb nyob deb yog ntau dua li txoj kab uas hla ntawm cov menyuam, kom cov menyuam tuaj yeem yob los ntawm lub ncov ntawm qhov qis-txoj kev sib haum xeeb mus rau lub hav thiab rov tsim dua tag nrho. waveform ntawm low-order harmonic nyob rau hauv. Nyob rau hauv cov txheej txheem ntawm lub voj voog radial ntaus, thiab rau cov txheej txheem nrog high-level harmonics, qhov kev sib haum xeeb seem nrug tsawg dua li txoj kab uas hla ntawm cov menyuam, kom cov menyuam tuaj yeem ncav cuag qhov siab tshaj plaws ntawm cov tshuaj hormones yam tsis tau kov lub hav, uas ua rau qis. High-level harmonics muaj kev cuam tshuam zoo rau kev sib hloov ntawm cov kabmob.
2. Cov nyhuv ntawm roundness yuam kev amplitude ntawm cov kabmob rotation raug
Qhov hloov pauv qhov yuam kev amplitude yog {{0}}.020mm thiab 0.060mm. Radial beating txheej txheem yog tig rau ib lub lim tiam. Nws tuaj yeem pom tau tias nrog qhov nce ntawm qhov amplitude ntawm qhov yuam kev roundness, lub nplhaib sab hauv radial beating tus nqi thiab nws cov nqi sib txawv ntawm qhov sib txawv tau nce ntau, thiab qhov kev sib hloov qhov tseeb ntawm cov kabmob kuj raug txo.
Qhov cuam tshuam ntawm qhov yuam kev amplitude ntawm qhov siab tshaj plaws radial ntaus nqi ntawm lub nplhaib puab. Nrog rau qhov nce ntawm qhov amplitude ntawm lub voj voog yuam kev amplitude nyob rau hauv lub nplhaib puab, lub siab tshaj plaws radial ntaus nqi ntawm lub puab nplhaib qhia tau hais tias ib tug tseem ceeb nce, uas kuj qhia txog lub puab puab lub rounding yuam kev amplitude ntawm txoj kev ncig yog ib qho ntawm cov tseem ceeb tshaj plaws. uas cuam tshuam qhov kev sib hloov raug ntawm cov kabmob.
3. Cov nyhuv ntawm cov menyuam cov lej ntawm kev sib hloov raug ntawm cov kabmob
Tus naj npawb ntawm cov yob yog tig li ntawm 8 thiab 14 teev rau ib lub lim tiam. Cov txheej txheem dhia radial yog 0.010mm, qhov sib txawv radial yog 0.040mm, thiab qhov kev sib haum xeeb yog 2. Nws tuaj yeem pom tau tias nrog kev nce ntawm cov chais, lub voj voog thiab amplitude ntawm lub nplhaib puab radial beating txheej txheem tau txo.
Qhov cuam tshuam ntawm tus naj npawb ntawm cov menyuam ntawm qhov siab tshaj plaws radial ntaus nqi ntawm lub nplhaib puab, qhov siab tshaj plaws radial ntaus nqi ntawm lub nplhaib puab maj mam txo nrog qhov nce ntawm cov menyuam Ge Su, thiab cov kev hloov pauv tau maj mam txo nrog qhov nce ntawm tus lej. ntawm rollers. Thiab qhov kev hloov pauv tau maj mam, uas qhia tau hais tias qhov nce ntawm cov chais nrog cov menyuam yaus me tuaj yeem txhim kho qhov kev sib hloov ntawm cov kabmob. Qhov no yog vim qhov nce ntawm cov rollers kom txo tau qhov ncua sij hawm ntawm cov menyuam uas nyob ib sab, thiab tib lub sijhawm, tus naj npawb ntawm cov menyuam rollers nyob rau sab hauv thiab sab nraud ntawm cov menyuam yaus nce.
4. Cov nyhuv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov kev sib hloov qhov tseeb ntawm cov kabmob
Qhov sib txawv radial yog {{0}} 02mm thiab 0.06mm. Ntawm lawv, qhov amplitude ntawm lub voj voog yuam kev yog 0.010mm, qhov kev sib haum xeeb yog 2, thiab tus naj npawb ntawm cov chais yog 10. Nws tuaj yeem pom tau tias raws li qhov sib txawv radial nce, lub voj voog thiab amplitude ntawm lub nplhaib puab radial beating txheej txheem muaj. tsis muaj nqi amplitude. pom tseeb hloov.
Cov nyhuv ntawm radial sib txawv ntawm qhov siab tshaj plaws radial ntaus nqi ntawm lub nplhaib puab tuaj yeem pom. Qhov siab tshaj plaws ntaus nqi ntawm lub nplhaib puab yog nce raws li qhov sib txawv radial nce, uas zoo ib yam li cov qauv ntawm linearly nce.
5. Cov ntsiab lus xaus
1) Nrog rau qhov nce ntawm qhov kev sib haum xeeb, qhov amplitude ntawm radial beating tus nqi ntawm lub nplhaib puab txo, thiab qhov siab tshaj plaws radial ntaus nqi ntawm lub nplhaib sab hauv qhia tau hais tias ib qho kev poob qis; Nyob rau tib lub sijhawm, qhov siab tshaj plaws radial ntaus nqi ntawm lub nplhaib puab mus txog tus nqi loj.
2) Nrog rau qhov nce ntawm qhov amplitude ntawm qhov yuam kev ncig, lub nplhaib sab hauv radial ntaus nqi thiab nws cov nqi amplitude tau nce ntau, thiab qhov siab tshaj plaws radial ntaus nqi ntawm lub nplhaib puab qhia tau hais tias muaj kev nce ntxiv. Qhov yuam kev amplitude yog ib qho ntawm cov ntsiab lus tseem ceeb uas cuam tshuam rau kev sib hloov qhov tseeb ntawm cov kabmob.
3) Thaum tus naj npawb ntawm cov kabmob me me, qhov amplitude ntawm lub nplhaib sab hauv radial beating tus nqi txo qis raws li tus naj npawb ntawm cov chais nce, thiab qhov siab tshaj plaws radial ntaus nqi ntawm lub nplhaib puab yog maj mam nce nrog kev nce ntawm cov chais. Txo qis, thiab cov kev hloov pauv tau maj mam maj mam.
4) Nrog rau qhov nce ntawm qhov sib txawv radial, qhov cuam tshuam ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov kev sib hloov ntawm cov kabmob yog me me, tab sis nws tsuas yog nce lub nplhaib sab hauv radial ntaus nqi.
