Qhov txawv ntawm A Series thiab B Series roller chains yog dab tsi?
Cov saw hlau yog cov khoom tseem ceeb hauv cov txheej txheem sib kis niaj hnub no thiab siv dav hauv ntau yam khoom siv kho tshuab. Raws li cov qauv sib txawv thiab cov xwm txheej siv,cov saw hlaufeem ntau yog muab faib ua A Series thiab B Series.
I. Cov Qauv thiab Keeb Kwm
A Series: Ua raws li American Standard for Chains (ANSI), tus qauv tseem ceeb hauv kev lag luam Asmeskas, thiab siv dav hauv North America.
B Series: Ua raws li European Standard for Chains (ISO), feem ntau yog nyob rau hauv UK, thiab siv dav hauv Tebchaws Europe thiab lwm thaj chaw.
II. Cov yam ntxwv ntawm cov qauv
Sab Hauv Thiab Sab Nraud Txuas Phaj Thickness:
A Series: Cov phaj txuas sab hauv thiab sab nraud yog cov tuab sib npaug, ua tiav lub zog zoo sib xws los ntawm kev hloov kho sib txawv.
B Series: Cov phaj txuas sab hauv thiab sab nraud muaj qhov tuab sib npaug, ua tiav lub zog zoo sib xws los ntawm kev txav sib txawv.
Qhov Loj ntawm Cheebtsam thiab Qhov Sib Piv ntawm Qhov Siab:
A Series: Qhov loj ntawm txhua yam khoom yog sib npaug rau qhov siab. Piv txwv li, txoj kab uas hla ntawm tus pin = (5/16) P, txoj kab uas hla ntawm lub roller = (5/8) P, thiab qhov tuab ntawm daim hlau saw = (1/8) P (P yog qhov siab ntawm cov saw).
B Series: Qhov loj ntawm cov khoom tseem ceeb tsis meej meej rau qhov suab.
Tsim Sprocket:
Ib Series: Sprockets tsis muaj bosses ntawm ob sab.
B Series: Tsav pulleys nrog lub boss ntawm ib sab, ruaj ntseg nrog lub qhov tseem ceeb thiab cov qhov ntsia hlau.
III. Kev Sib Piv Kev Ua Tau Zoo
Lub zog tensile:
A Series: Hauv yim qhov loj ntawm 19.05 txog 76.20 hli, lub zog tensile loj dua li ntawm B Series.
B Series: Hauv ob qhov loj ntawm 12.70 hli thiab 15.875 hli, lub zog tensile loj dua li ntawm A Series.
Kev Sib Txawv ntawm Qhov Ntev ntawm Saw:
A Series: Qhov sib txawv ntawm qhov ntev ntawm saw yog + 0.13%.
B Series: Qhov sib txawv ntawm qhov ntev ntawm cov saw yog + 0.15%. Qhov chaw txhawb nqa ntawm pob khawm:
A Series: Muab thaj chaw txhawb nqa loj tshaj plaws ntawm 15.875 mm thiab 19.05 mm qhov loj me.
B Series: Muaj thaj chaw txhawb nqa loj dua 20% piv rau A Series nrog tib qhov dav txuas sab hauv.
Txoj kab uas hla ntawm cov menyuam:
A Series: Txhua lub suab tsuas muaj ib qho loj me ntawm cov menyuam.
B Series: Lub txoj kab uas hla ntawm cov menyuam yog 10% -20% loj dua li A Series, nrog rau ob lub dav ntawm cov menyuam muaj rau txhua lub suab.
IV. Cov Xwm Txheej Thov
Ib Series:
Nta: Haum rau cov kab ke kis tau nruab nrab thiab qis-ceev.
Daim Ntawv Thov: Siv dav hauv kev siv tshuab, tshuab ua liaj ua teb, kev tsim khoom tsheb, metallurgy, petrochemicals, thiab lwm yam lag luam.
B Series:
Nta: Haum rau kev txav mus los ceev ceev, kev sib kis tas mus li, thiab cov khoom hnyav.
Daim Ntawv Thov: Feem ntau siv rau hauv kev siv tshuab, tshuab hlau, tshuab textile, thiab lwm yam kev siv.
V. Kev Saib Xyuas thiab Kev Saib Xyuas
Ib Series:
Kev Nruj: Kev nruj qis = 1.5%a. Tshaj 2% ua rau muaj kev pheej hmoo ntawm cov hniav dhia ntxiv 80%.
Kev Siv Lubrication: Haum rau qhov kub thiab txias, siv cov roj graphite.
B Series:
Kev Nruj: Kev nruj qis = 1.5%a. Tshaj 2% ua rau muaj kev pheej hmoo ntawm cov hniav dhia ntxiv 80%.
Kev Siv Lubrication: Haum rau cov chaw muaj ntsev tsuag xeb, siv cov phaj saw hlau uas muaj Dacromet thiab siv lubrication txhua peb lub hlis.
VI. Cov Lus Qhia Txog Kev Xaiv
Xaiv raws li qhov xwm txheej ntawm daim ntawv thov: Yog tias koj cov khoom siv yuav tsum tau ua haujlwm hauv qab qhov nruab nrab thiab qhov ceev qis, A Series yuav yog qhov kev xaiv zoo dua; yog tias nws xav tau qhov ceev siab, kev sib kis tas mus li, thiab cov khoom hnyav, B Series yog qhov tsim nyog dua.
Xav txog cov nqi kho: Muaj qee qhov sib txawv ntawm kev kho ntawm A thiab B Series. Thaum xaiv, xav txog qhov chaw ua haujlwm ntawm cov khoom siv thiab cov peev txheej kho.
Xyuas kom meej tias sib xws: Thaum xaiv cov saw, xyuas kom meej tias qhov sib txawv ntawm cov saw thiab sprocket sib xws kom tsis txhob muaj teeb meem kis.
