Kab mob kis tau tus kab mob yog tsim los ntawm cov cab cab thiab cov cab cab, thiab feem ntau cov cab cab yog qhov ua haujlwm. Cov cab iav muaj tib txoj cai-tes thiab sab laug-tes threads, uas yog hu ua txoj cai-tes thiab sab laug-tes worm gears feem. Tus cab yog ib lub iav nrog ib los yog ntau dua helical cov hniav uas meshes nrog lub log cab los ua ib qho staggered ncej iav khub. Lub indexing nto tuaj yeem yog cylindrical, conical lossis ncig, thiab muaj plaub pawg ntawm Archimedes worm, involute worm, ib txwm ncaj profile worm, thiab tapered enveloping cylindrical worm.
Qhov zoo ntawm worm gear kis tau tus mob.
✦ Qhov sib piv ntawm ib-theem kis tau tus mob loj, feem ntau i = 10 ~ 100. Nyob rau hauv lub indexing mechanism rau kev xa xov hluav taws xob, qhov siab tshaj plaws tuaj yeem yog tshaj 1500.
✦ Tib meshing yog linear contact, uas tuaj yeem tiv taus lub zog loj.
✦ Compact qauv, du kis tau tus mob, thiab tsis muaj suab nrov.
✦ Thaum lub kaum sab xis ntawm cov cab cab tsawg dua qhov sib npaug ntawm qhov sib txhuam ntawm cov iav, nws yog tus kheej-locking nrog counter-stroke, piv txwv li, tsuas yog cov cab cab tuaj yeem tsav lub log cab, tsis yog lub log cab.
Disadvantages ntawm worm gear tsav.
✦Nrog ob lub axes perpendicular, linear tshaj tawm ntawm ob lub log nodes yog perpendicular, yog li tus txheeb ze zawv zawg ceev yog loj, yooj yim rau cua sov thiab hnav.
✦ Tsawg efficiency, feem ntau 0.7 txog 0.8; worm gears nrog tus kheej-locking worm gears txawm tias tsawg dua, feem ntau tsawg dua 0.5.
Puas yog aworm gear stepper motoryuav tsum muaj kev ntsuas tus kheej?
Tsis yog, muaj qhov yuav tsum tau ua ua ntej. Thaum lub kaum sab xis txhuas < txhuam lub kaum sab xis, lubworm gear stepper motortuaj yeem kaw tus kheej.
Feem ntau thaum xaiv cov iav txo qis stepper lub cev muaj zog, tus neeg siv yuav tsum siv lub zog tsis ua haujlwm tiv thaiv lossis nres lub cev muaj zog, yog li lub iav txo lub cev muaj zog yuav raug xaiv nrog lub nres kom ua tiav lub hom phiaj ntawm kev nres, tab sis tsis txhais tau tias nres, me ntsis inertia tseem nyob ntawd.
Qhov ntsuas tus kheej yog dab tsi?Lub tswv yim ntawm kev ntsuas tus kheej yog tias txawm tias lub zog ntau npaum li cas tsis tuaj yeem pib, txawm tias ntau npaum li cas inertia, tsuav yog qhov ua haujlwm ntawm qhov ua haujlwm kom tsis txhob khiav, tag nrho lub tshuab tuaj yeem nres, worm gear geared stepper motor muaj qhov kev ua haujlwm ntawm tus kheej. Tsis muaj kev ntsuas tus kheej rau kev ua haujlwm ntawm cov kauj ruam stepper motors, thiab muaj kev txhim khu kev qha ntawm tus kheej ntsuas phoo rau cab iav reducers nrog ceev piv ntawm 1: 30 thiab siab dua, thiab qhov loj dua qhov txo qis, qhov zoo dua qhov kev ntsuas tus kheej.
Yuav ua li cas xaiv qhov txo qis kom ntseeg tau qhov kev ua haujlwm ntawm tus kheej ntawm tus cab iav stepper lub cev muaj zog?
1 、 Cov iav iav kev sib txhuam coefficient yog 0.6, lub iav iav qhia lub kaum sab xis yog tsawg dua 3 ° 29′ 11 ″ uas yog qhov ntsuas tus kheej, thiab lwm yam.
2 、 Cov iav iav kev sib txhuam coefficient yog 0.7, lub iav iav qhia lub kaum sab xis yog tsawg dua 4° 03′ 57 ″ uas yog qhov ntsuas tus kheej, thiab lwm yam.
3, Thaum qhov kev sib txhuam coefficient ntawm lub log cab yog 0.8, lub kaum sab xis ntawm cov cab cab yog tsawg dua 4 ° 38'39 ", uas yog, nws tus kheej-locking, thiab vice versa.
Thaum lub kaum sab xis ntawm cov cab cab tsawg dua qhov sib npaug ntawm qhov sib npaug ntawm cov hniav ntawm lub meshing lub log, qhov txo qis stepper lub cev muaj zog mechanism muaj qhov ntsuas tus kheej, uas tuaj yeem ua tiav rov qab tus kheej xauv, uas yog, tsuas yog cov cab cab tuaj yeem tsav lub log cab, tab sis tsis yog cov cab cab tsav lub cab cab. Feem ntau hauv kev tsim cov tshuab hnyav, cov neeg tsim qauv nyiam siv cov cab iav iav nrog nws tus kheej-locking, vim tias nws rov qab xauv tus kheej tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev nyab xeeb.
Kev suav cov mis ntawm worm log thiab cab iav.
1. Kev sib kis piv = tus naj npawb ntawm cov iav iav hniav ÷ tus naj npawb ntawm cov cab taub hau
2.Center nrug = (worm log pitch + cab iav pitch) ÷ 2
3, Worm log inch = (cov hniav + 2) × modulus
4, Worm log pitch = module × tus lej ntawm cov hniav
5 、 Kab laum = kab kab sab nraud-2 × module
6, Kab qhia = π × module × taub hau
7, Helix lub kaum sab xis (qhia lub kaum ntse ntse) tgB = (modulus × lub taub hau naj npawb) ÷worm suab
8, Kab hlau rhuav = π × module × taub hau
9, Modulus = txoj kab uas hla ntawm indexing voj voog / tus naj npawb ntawm cov hniav
Tus nab npawb ntawm cov cab: ib lub taub hau cab (tseem muaj ib lub helix ntawm tus cab, piv txwv li tus cab tig rau ib lub lis piam thiab cov cab cab tig los ntawm ib tus hniav); ob lub taub hau cab (muaj ob lub helixes ntawm tus cab, piv txwv li tus cab tig rau ib lub lis piam thiab lub log cab tig los ntawm ob tug hniav).
Modulus yog qhov loj ntawm lub helix ntawm cov ntsia hlau, piv txwv li qhov loj dua lub modulus, qhov loj dua lub helix ntawm cov ntsia hlau.
Txoj kab uas hla yog qhov tuab ntawm cov ntsia hlau.
Modulus: Lub voj voog indexing ntawm ib lub iav yog qhov ntsuas rau kev tsim thiab xam qhov ntev ntawm txhua qhov ntawm lub iav, thiab qhov ncig ntawm lub iav indexing lub voj voog = πd = zp, yog li txoj kab uas hla ntawm lub voj voog indexing.
d = np/π
Txij li π yog tus lej irrational nyob rau hauv kab zauv saum toj no, nws tsis yooj yim rau qhov chaw ntawm lub voj voog ntsuas raws li kev siv. Txhawm rau ua kom yooj yim rau kev suav, tsim khoom thiab tshuaj xyuas, qhov piv ntawm p / π tam sim no tau muab teev tseg raws li qee qhov txiaj ntsig yooj yim, thiab qhov piv yog hu ua modulus (module), qhia raws li m.
Hom worm gearing
Raws li cov duab sib txawv ntawm cov cab cab, cov cab tuaj yeem muab faib ua cylindrical worm drive, annular worm drive thiab conical worm drive. Ntawm lawv, cylindrical worm tsav yog siv dav tshaj plaws.
Ordinary cylindrical worm gears feem ntau yog txiav rau ntawm lub tshuab dhos nrog lub cuab yeej tig nrog lub tsheb npav ncaj. Nrog rau qhov sib txawv ntawm cov cuab yeej kev teeb tsa thiab cov cuab yeej siv, plaub hom cab iav nrog cov hniav sib txawv ntawm qhov sib txawv ntawm qhov ntsug axis tuaj yeem tau txais: involute worm gears (ZI type), Archimedes worm gears (ZA type), normal straight profile worm gears (ZN), thiab tapered enveloping cylindrical worm gears (Z).
Involute worm (ZI hom)- lub dav hlau hniav yog tangent rau lub tog raj kheej cab, thiab cov hniav kawg yog involute, haum rau kev ceev dua thiab lub zog loj.
Archimedean worm (hom ZA)- Cov hniav profile perpendicular mus rau lub dav hlau axis yog Archimedean ntsia hlau, thiab cov hniav profile nyob rau hauv lub dav hlau dhau los ntawm lub axis yog ncaj, yooj yim ua thiab tsawg raug. (Axial ncaj profile cab iav).
Ib txwm ncaj profile worm (ZN)- tuaj yeem siv los zom cov hniav nrog kev hloov kev sib tsoo log, kev ua haujlwm yooj yim, feem ntau siv rau ntau lub taub hau cab, kev sib kis tau zoo txog 0.9.
