Cov hlua khi yog ib hom saw hlau siv los xa cov tshuab hluav taws xob. Nws yog ib hom kev tsav tsheb thiab siv dav hauv tsev neeg, kev lag luam thiab kev ua liaj ua teb, nrog rau cov khoom siv conveyors, plotters, tshuab luam ntawv, tsheb, maus taus, thiab tsheb kauj vab. Nws yog txuas ua ke los ntawm ib tug series ntawm luv luv cylindrical rollers thiab tsav los ntawm ib tug iav hu ua ib tug sprocket, uas yog ib tug yooj yim, txhim khu kev qha thiab muaj peev xwm kis tau tus mob.
1.Taw qhia rau Roller Chain:
Cov menyuam chains feem ntau xa mus rau precision roller chains rau luv-pitch kis tau tus mob, feem ntau siv dav thiab tso zis ntau tshaj plaws. Cov menyuam chains muab faib ua ib kab thiab ntau kab, haum rau me me fais fab kis. Qhov yooj yim parameter ntawm cov menyuam saw yog cov saw txuas p, uas yog sib npaug rau cov saw xov tooj ntawm cov menyuam saw sib npaug los ntawm 25.4/16 (mm). Muaj ob hom lus kawg hauv cov xov tooj, A thiab B, qhia txog ob lub koob, thiab ob lub koob ntxiv rau ib leeg.
2.roller chain muaj pes tsawg leeg:
Cov menyuam saw hlau yog tsim los ntawm cov saw hlau sab hauv 1, cov saw hlau sab nrauv 2, tus pin ncej 3, lub tes tsho 4 thiab cov menyuam 5. Cov saw hlau sab hauv thiab lub tes tsho, cov saw hlau sab nraud thiab tus pin yog txhua yam cuam tshuam. ; cov chais thiab lub tes tsho, thiab lub tes tsho thiab tus pin yog tag nrho cov clearance fits. Thaum ua haujlwm, cov hlua txuas sab hauv thiab sab nraud tuaj yeem cuam tshuam qhov sib txawv ntawm ib leeg, lub tes tsho tuaj yeem tig tau ywj pheej nyob ib ncig ntawm tus pin ncej, thiab cov menyuam tau teem rau ntawm lub tes tsho kom txo tau qhov hnav ntawm cov saw thiab sprocket. Txhawm rau txo qhov hnyav thiab ua kom lub zog ntawm txhua ntu sib npaug, cov saw hlau sab hauv thiab sab nrauv feem ntau ua rau "8" zoo li. [2] Txhua feem ntawm cov saw hlau yog ua los ntawm carbon steel lossis hlau alloy. Feem ntau los ntawm kev kho cua sov kom ua tiav qee lub zog thiab hardness.
3.Roller Chain Pitch:
Qhov nruab nrab-rau-nruab nrab nruab nrab ntawm ob tus pin shafts uas nyob ib sab ntawm cov saw yog hu ua saw pitch, qhia los ntawm p, uas yog qhov tseem ceeb tshaj plaws ntawm cov saw hlau. Thaum lub suab nce, qhov loj ntawm txhua qhov ntawm cov saw hlau nce raws li, thiab lub zog uas tuaj yeem kis tau kuj nce raws li. [2] Cov saw pitch p yog sib npaug rau cov xov tooj ntawm cov menyuam saw sib npaug los ntawm 25.4/16 (mm). Piv txwv li, saw tooj 12, cov menyuam saw pitch p = 12 × 25.4 / 16 = 19.05mm.
4.Cov qauv ntawm cov menyuam saw:
Roller chains muaj nyob rau hauv ib leeg thiab ntau kab. Thaum nws yog ib qho tsim nyog yuav tsum tau nqa lub nra hnyav dua thiab xa lub zog loj, ntau kab ntawm cov chains tuaj yeem siv tau, raws li pom hauv daim duab 2. Cov kab ntau kab sib npaug sib npaug rau ob peb kab ib kab txuas nrog ib leeg los ntawm cov pins ntev. Nws yuav tsum tsis txhob ntau dhau, feem ntau siv yog ob-kab chains thiab peb-kab chains.
5.Roller Link Joint Form:
Qhov ntev ntawm cov saw hlau yog sawv cev los ntawm tus naj npawb ntawm cov saw txuas. Feem ntau, ib qho kev sib txuas ntawm tus lej sib txuas yog siv. Nyob rau hauv txoj kev no, cais pins los yog caij nplooj ntoos hlav clips yuav siv tau ntawm cov pob qij txha ntawm cov saw. Thaum cov saw hlau nkhaus nyob rau hauv qhov nro, lub sijhawm khoov ntxiv yuav raug tsim, thiab feem ntau yuav tsum zam kom deb li deb tau
6.Roller chain standard:
GB / T1243-1997 qhia tias cov hlua khi rau cov menyuam tau muab faib ua A thiab B series, ntawm cov A series yog siv rau kev kub ceev, hnyav hnyav thiab kis tau tus mob tseem ceeb, uas yog siv ntau dua. Cov xov tooj sib npaug los ntawm 25.4 / 16mm yog tus nqi suab. B series yog siv rau kev sib kis dav dav. Lub cim ntawm cov menyuam saw yog: saw tooj ib kab tus lej ib txoj hlua txuas tus lej ib tus lej lej. Piv txwv li: 10A-1-86-GB / T1243-1997 txhais tau tias: A series roller saw, lub suab yog 15.875mm, ib kab, tus lej txuas yog 86, tus qauv tsim GB / T1243-1997
7.Daim ntawv thov ntawm roller chain:
Chain tsav yog dav siv nyob rau hauv ntau yam machinery nyob rau hauv ntau yam industries xws li kev ua liaj ua teb, mining, metallurgy, petrochemical kev lag luam thiab lifting tsheb thauj mus los. Lub zog uas cov saw hlau kis tau tuaj yeem ncav cuag 3600kW, thiab feem ntau yog siv rau lub zog qis dua 100kW; cov saw ceev tuaj yeem ncav cuag 30 ~ 40m / s, thiab cov saw siv feem ntau yog qis dua 15m / s; ~ 2.5 yog haum.
8.Feature ntawm roller chain drive:
qhov zoo:
Piv nrog rau txoj siv tawv tsav, nws tsis muaj qhov zawv zawg zawv zawg, tuaj yeem tswj tau qhov tseeb qhov nruab nrab kis tau tus mob, thiab muaj kev sib kis tau zoo; cov saw tsis tas yuav tsum muaj lub zog nruj, yog li lub nra ntawm lub ncej thiab cov kabmob me me; nws yuav tsis plam, kis tau tus mob yog txhim khu kev qha, thiab lub overload Strong muaj peev xwm, yuav ua hauj lwm zoo nyob rau hauv qis ceev thiab hnyav load.
tsis txaus:
Ob qho tib si cov saw nrawm nrawm thiab qhov hloov pauv hloov pauv sai sai, kev sib kis tsis zoo, thiab muaj kev poob siab thiab suab nrov thaum ua haujlwm. Nws tsis haum rau lub sijhawm siab ceev, thiab nws tsis haum rau kev hloov pauv ntawm cov kev taw qhia ntawm kev sib hloov.
9.txheej txheem invention:
Raws li kev tshawb fawb, kev siv cov chains hauv Suav teb muaj keeb kwm ntau dua 3,000 xyoo. Nyob rau hauv Suav teb thaum ub, cov tsheb thauj khoom thiab cov tsheb thauj khoom siv los nqa dej los ntawm qhov qis mus rau qhov siab zoo ib yam li cov saw hlau niaj hnub. Nyob rau hauv "Xinyixiangfayao" sau los ntawm Su Song nyob rau sab qaum teb Song Dynasty ntawm Tuam Tshoj, nws tau sau tseg tias dab tsi ua rau kev sib hloov ntawm lub armillary sphere yog zoo li cov saw hlau kis tau tus mob ua los ntawm niaj hnub hlau. Nws tuaj yeem pom tau tias Tuam Tshoj yog ib lub tebchaws ntxov tshaj plaws hauv kev siv saw hlau. Txawm li cas los xij, cov qauv tseem ceeb ntawm cov saw hlau niaj hnub no tau tsim thawj zaug thiab tau thov los ntawm Leonardo da Vinci (1452-1519), tus kws tshawb fawb zoo thiab kws kos duab hauv European Renaissance. Txij thaum ntawd los, xyoo 1832, Galle hauv Fab Kis tau tsim cov saw hlau, thiab xyoo 1864, Slaite sleeveless roller chain in Britain. Tab sis nws yog Swiss Hans Reynolds uas tau mus txog theem ntawm cov qauv saw niaj hnub tsim. Xyoo 1880, nws tau ua tiav qhov tsis txaus ntawm cov qauv saw yav dhau los, tsim cov saw hlau rau hauv cov txheej txheem nrov ntawm cov menyuam chains, thiab tau txais cov menyuam saw hauv UK. chain invention patent.
