Pob Screw Lead: Kev Lag Luam Ntawm Kev Ceev, Thrust thiab Resolution
"Koj puas tuaj yeem xa kuv 1610 es tsis yog 1605? Tib lub taub hau, nrawm dua."
Tib txoj kab uas hla, yog. Tib ntsia hlau, tsis muaj. Doubling cov hlau lead ua ob npaug rau kev mus ncig ib kiv puag ncig, thiab nws kuj halves lub zog koj tau txais los ntawm tib lub cev muaj zog torque thiab halves koj qhov kev daws teeb meem. Qee zaum qhov ntawd yog qhov kev lag luam zoo. Qee lub sij hawm nws ntsiag to tsoo lub axis.
Lead yog ib qho kev qhia tshwj xeeb uas feem ntau hloov pauv li cas axis coj, thiab nws yog qhov feem ntau hloov pauv tsis tu ncua.
Dab tsi Lead tiag tswj
Lead yog lub axial nrug cov txiv ntoo mus rau ib lub taub hau tig. Nws zaum hauv nruab nrab ntawm peb txoj kev sib raug zoo, thiab koj tsis tuaj yeem txav ib qho tsis txav mus rau lwm tus.
Ceev.Linear ceev=lub cev muaj zog rpm × lead. A 5 mm lead ntawm 3000 rpm muab 15 m / min. Ib qho 10 mm lead ntawm tib rpm muab 30 m / min. Qhov no yog kev sib raug zoo uas txhua tus paub thiab yog vim li cas tib neeg thov kom coarser coj.
Ntiv.Lead coj zoo li lub iav piv. Muab ob npaug rau cov txhuas roughly ib nrab ntawm lub zog axial muaj los ntawm lub cev muaj zog torque. Lub tshuab kom zoo dua koj poob tsis rov qab los.
Kev daws teeb meem.Linear daws teeb meem=lead ÷ encoder suav rau ib lub kiv puag ncig. Nrog rau 1000-count encoder, 5 mm lead daws 5 µm ib suav; ib 10 mm lead daws 10 µm. Koj qhov kev tswj hwm tuaj yeem cuam tshuam, tab sis nws tsis tuaj yeem tsim kho cov kev daws teeb meem uas tsis nyob ntawd.
Koj tuaj yeem xaiv ob ntawm peb. Tsis muaj hlau lead uas yog ceev, muaj zog, thiab zoo.
Teeb meem Vertical Axis
Qhov no yog qhov kev hloov pauv ntawm cov hlau lead ua rau kev puas tsuaj tiag tiag.
Ib tug zoo- txhuas ntsia hlau muaj ib tug ntiav helix lub kaum sab xis thiab yog kuj resistant rau rov qab- tsav tsheb - thawb rau ntawm lub txiv ntseej thiab cov ntsia hlau tsis yooj yim tig. A ntxhib-cov ntsia hlau muaj lub kaum sab xis helix thiab nraub qaum- tsav tau yooj yim.
Ntawm qhov ntsug axis, qhov sib txawv yog qhov sib txawv ntawm lub load uas nyob twj ywm thaum lub hwj chim raug tshem tawm thiab lub nra uas nqis los hauv lub ntiajteb txawj nqus.
Tsis txhob kho tus kheej -locking raws li tus qauv tsim los tso siab rau, txawm tias muaj cov hlau lead zoo - kev sib txhuam nws txawv nrog lubrication, kub, hnav, thiab thauj khoom, thiab cov ntsia hlau uas tuav ntawm lub rooj zaum yuav tsis tuav tom qab rau lub hlis ntawm kev pabcuam. Yog hais tias ib tug ntsug axis yuav tsum tuav txoj hauj lwm tsis muaj hwj chim, qhia kom meej lub cev muaj zog nres. Kho ib tus kheej - kaw tus cwj pwm raws li qhov txiaj ntsig, tsis yog kev nyab xeeb.
Thaum koj nce cov hlau lead ntawm qhov ntsug axis uas twb muaj lawm, xyuas peb yam: lub cev muaj zog torque tiv thaiv qhov kev xav tau tshiab, tuav nres ntsuas, thiab dab tsi tshwm sim ntawm lub zog poob.
Lead thiab Critical Speed yog ywj siab
Ib qho kev xav ntau: "cov hlau lead ntxhib txhais tau tias lub axis tuaj yeem mus sai dua." Tsuas yog ib feem.
Coarse lead txhais tau hais tias ntau dua mus rau ib lub kiv puag ncig, yog li koj ncav cuag ib qho kev nrawm nrawm ntawm qis rpm. Uas tiag pab, vimceev ceevyog qhov txwv ntawm kev sib hloov ceev, thiab khiav qeeb hauv rpm ua rau koj ntxiv ntawm nws.
Tab sis tus nqi DN - nominal txoj kab uas hla multiplied los ntawm rpm - thiab cov txiv ntseej tus kheej ceev ntsuas yog cais txwv teem los ntawm cov txiv ntseej thiab xa rov qab system tsim, tsis yog los ntawm txhuas. Cov txiv ntseej ntxhib- cov hmoov txhuas tsis tuaj yeem nqa qhov ntsuas DN siab dua li qhov nplua - cov txiv ntseej ntawm tib txoj kab uas hla.
Tshawb xyuas cov chaw tsim khoom lag luam luam tawm ceev ceev thiab DN txwv rau cov qauv tshwj xeeb uas koj tab tom yuav. Tsis txhob suav ib qho ntawm lwm tus.
Xaiv Tus Lead los ntawm Daim Ntawv Thov
Ua haujlwm rov qab los ntawm qhov axis yuav tsum ua.
Pib nrog qhov xav tau linear ceev thiab muaj lub cev muaj zog rpm.Yam tsawg kawg nkaus=yuav tsum tau ceev ÷ usable rpm. Qhov no muab rau koj pem teb.
Kos lub thrust ntawm cov hlau lead.Coj koj qhov phem tshaj - rooj plaub axial load, ntxiv acceleration quab yuam thiab kev sib txhuam, thiab paub meej tias lub cev muaj zog tuaj yeem xa nws los ntawm cov hlau lead uas xaiv nrog cov npoo. Yog tias tsis yog, koj xav tau ntau lub zog los yog cov hlau lead zoo dua.
Tshawb xyuas kev daws teeb meem.Faib tus thawj coj los ntawm koj qhov kev daws teeb meem encoder thiab sib piv rau koj qhov kev kam rau ua qhov chaw. Tawm hauv taub hau - kev daws teeb meem txhua yam tsis zoo ib yam li qhov ua tiav tau, uas tseem nyob ntawm cov ntsia hlauqib raug, backlash, thiab nruj.
Tom qab ntawd xyuas qhov ceev ceev thiab DNntawm rpm implied los ntawm koj xaiv lead.
Yog tias tus lej tsis kaw, cov lus teb feem ntau yog qhov loj dua es tsis yog cov hlau lead sib txawv. Txoj kab uas hla yuav koj qhov tseem ceeb ceev, nruj, thiab muaj peev xwm thauj khoom ib txhij.
Cov kev xaiv ua thawj coj hauv kev xyaum
Dab tsi peb pom feem ntau, los ntawm hom ntawv thov:
- Lead=5 hlintawm 16-25 hli shafts: dav CNC, routers, engraving, feem ntau positioning ua hauj lwm. Lub neej ntawd rau qhov laj thawj zoo.
- Lead=10 hli: Plasma thiab laser rooj, axes qhov twg traverse dominates lub voj voog, loj gantry.
- Lead=16–20 mm thiab siab dua: xaiv-thiab- qhov chaw, hloov chaw, palletising, ntev -stroke tuav.
- Lead=1–2 mmntawm cov shafts me me: cov theem kho qhov muag, cov khoom siv kho mob, qhov chaw zoo nyob qhov twg qhov kev txav yog luv.
Cov no yog cov ntsiab lus pib, tsis yog txoj cai. Lub voj voog ua haujlwm txawv txawv yeej ntaus ib pawg txhua lub sijhawm.
Yog tias koj tab tom hloov Lead ntawm lub tshuab uas twb muaj lawm
Cov ntsia hlau tsis yog ib qho poob - hauv kev sib pauv txawm tias txoj kab uas hla thiab ncej xaus sib phim.
Recheck: lub cev muaj zog torque tiv thaiv qhov kev sib tw tshiab, tsav kev sib tw thiab nce qhov chaw, xws li lub suab / coj tsis zoo, kev daws teeb meem tawm tsam qhov chaw spec, thiab - ntawm txoj kab ntsug - tus nres. Lub tshuab uas khiav kom raug ntawm 1605 tuaj yeem coj tus cwj pwm tsis zoo ntawm 1610 nrog tib lub chaw tswj tsis tau kov.
Nws yog qhov kev hloov pauv ncaj qha thaum cov lej raug kuaj ua ntej. Nws ua rau tsis meej pem qhov txhaum thaum lawv tsis yog.
Qhia Peb Lub Luag Haujlwm, Tsis Yog Tus Naj Npawb
Thaum cov neeg muas zaub xa ib feem naj npawb, peb hais tus naj npawb. Thaum lawv xa cov dej num - stroke, ceev, load, orientation, kam rau ua - peb muaj peev xwm feem ntau taw tes hais tias ib tug txawv txhuas los yog txoj kab uas hla mus txog lub hom phiaj nrog ib tug me me lub cev muaj zog los yog ib tug pheej yig dua ntsia hlau.
Qhov kev sib tham ntawd raug nqi ib qho email thiab tsis tu ncua txuag ntau dua li tus nqi sib txawv ntawm cov ntsia hlau.
