1. Yog vim li cas rau stepper motors nrog gearboxes
Stepper lub cev muaj zog hloov qhov zaus ntawm lub stator theem tam sim no, xws li hloov cov tswv yim mem tes ntawm stepper motor tsav Circuit Court, kom nws dhau los ua lub zog qis. Tsawg-ceev stepping lub cev muaj zog tos rau cov lus qhia stepping, lub rotor yog nyob rau hauv lub xeev ntawm nres, nyob rau hauv lub qis-ceev stepping, ceev fluctuations yuav loj, nyob rau hauv lub sij hawm no, xws li hloov mus rau high-ceev khiav lag luam, yuav daws tau qhov teeb meem ntawm ceev fluctuations, tab sis lub torque yuav tsis txaus. Ntawd yog, qhov hloov pauv ntawm lub zog qis qis, thiab kev kub ceev torque yuav tsis txaus, yog li qhov yuav tsum tau siv lub reducer.
2. Stepping motor feem ntau nrog dab tsi reducer
Reducer yog ib hom kev ywj pheej ntawm cov iav kis tau tus mob, cab iav kis tau tus mob thiab iav-worm kis tau tus mob nyob rau hauv ib tug nruj lub plhaub, uas yog feem ntau yog siv raws li ib tug deceleration kis tau tus mob ntaus ntawv ntawm lub prime mover thiab lub tshuab ua hauj lwm, thiab plays lub luag hauj lwm ntawm kev sib piv cov rotational ceev thiab xa lub torque ntawm lub prime mover thiab lub tshuab ua hauj lwm los yog lub actuator;
Muaj ntau hom reducers, uas tuaj yeem muab faib ua iav reducer, worm reducer thiab planetary iav reducer raws li hom kev sib kis, thiab ib-theem thiab ntau theem reducers raws li tus naj npawb ntawm cov theem sib kis;
Raws li cov duab ntawm lub iav tuaj yeem muab faib ua cylindrical iav reducer, bevel iav reducer thiab cone - cylindrical iav reducer;
Raws li daim ntawv ntawm kev sib kis tau tuaj yeem muab faib ua cov expansion hom reducer, shunt type reducer thiab coaxial type reducer.
Stepping motor sib dhos reducer planetary reducer, worm iav reducer, parallel iav reducer, ntsia hlau iav reducer.
Yuav ua li cas txog stepper motor planetary gearhead precision?
Gearhead precision tseem hu ua qhov rov qab tshem tawm, qhov tso zis yog tsau, cov tswv yim yog tig clockwise thiab counterclockwise, yog li ntawd thaum cov zis tsim lub ntsuas torque +-2% torque, cov tswv yim ntawm lub gearhead muaj qhov me me angular txav, qhov kev hloov pauv no yog qhov rov qab tshem tawm. Chav tsev yog "arc feeb", piv txwv li ib tug sixtieth ntawm ib degree. Qhov ib txwm rov qab clearance tus nqi yog hais txog cov zis sab ntawm lub gearhead.
Stepping lub cev muaj zog planetary gearbox muaj cov yam ntxwv ntawm siab rigidity, siab precision (ib theem yuav ua tau tiav nyob rau hauv 1 feeb), high kis tau tus mob efficiency (ib theem nyob rau hauv 97% -98%), siab torque / ntim piv, txij nkawm-dawb thiab hais txog. Pej xeem naj npawb "Mechanical Engineering Literature", engineer's petrol station!
Kev sib kis precision ntawm lub tshuab stepper tsis tuaj yeem hloov kho, lub kaum sab xis ntawm lub tshuab stepper tau txiav txim siab tag nrho los ntawm cov kauj ruam ntev thiab cov pulses, thiab tus naj npawb ntawm pulses tuaj yeem suav tag nrho, cov lej digital tsis muaj nyob rau hauv lub tswv yim ntawm precision, ib kauj ruam yog ib kauj ruam, thiab ob kauj ruam yog ob kauj ruam.
Tam sim no, qhov tseeb uas tuaj yeem ua kom zoo dua yog qhov tseeb ntawm lub iav rov qab qhov sib txawv ntawm lub ntiaj teb reducer gearbox:
1. Spindle precision hloov txoj kev:
Kev hloov kho qhov tseeb ntawm lub ntiaj teb reducer spindle, yog tias qhov kev ua yuam kev ntawm lub spindle nws tus kheej ua tau raws li qhov yuav tsum tau ua, ces qhov tseeb ntawm kev sib hloov ntawm lub reducer spindle feem ntau txiav txim siab los ntawm cov bearings.
Tus yuam sij rau kev kho qhov tseeb ntawm qhov spindle yog kho cov kabmob clearance. Kev tswj kom muaj qhov tsim nyog tshem tawm yog qhov tseem ceeb rau kev ua haujlwm ntawm cov khoom siv spindle thiab bearing lub neej.
Rau dov bearings, thaum muaj kev tshem tawm loj, tsis yog tsuas yog yuav ua rau lub cev muaj zog ntawm lub dov lub cev ntawm lub zog, tab sis kuj nyob rau hauv cov kabmob sab hauv thiab sab nraud ntawm lub nplhaib sib txuas los tsim qhov tshwm sim ntawm kev ntxhov siab loj, ua rau lub neej luv luv, tab sis kuj ua rau lub spindle center kab drift, yooj yim ua rau kev vibration ntawm spindle qhov chaw.
Yog li ntawd, qhov kev hloov ntawm dov bearings yuav tsum tau pre-loaded, thiaj li hais tias cov kabmob nyob rau hauv lub tsim ntawm ib tug tej yam nyiaj tshuav nyiaj li cas, thiaj li yuav ua tau ib tug tej yam elastic deformation nyob rau hauv lub dov lub cev thiab lub puab thiab sab nplhaib raceway kev sib cuag, thiaj li mus txhim kho qhov nruj ntawm cov kabmob.
2. Kev hloov ntawm txoj kev tshem tawm:
Planetary reducer nyob rau hauv cov txheej txheem ntawm kev txav yuav tsim kev sib txhuam, ua rau muaj kev hloov pauv ntawm qhov loj me, cov duab thiab qhov zoo ntawm qhov chaw, thiab tsim kev hnav thiab tsim kua muag, yog li ntawd qhov kev tshem tawm ntawm cov khoom nrog nce ntxiv, lub sijhawm no peb yuav tsum ua kom muaj qhov tsim nyog ntawm kev hloov kho kom ntseeg tau qhov tseeb ntawm cov txheeb ze txav ntawm cov khoom.
3. Kev them nyiaj yuam kev:
Qhov chaw ntawm lawv tus kheej yuam kev los ntawm kev sib dhos kom raug, kom qhov tshwm sim ntawm kev sib nrig sib offset thaum lub sij hawm so-nyob rau hauv lub sij hawm kom paub tseeb tias qhov tseeb ntawm cov khoom txav trajectory.
4. Comprehensive them txoj kev:
Siv lub reducer nws tus kheej los txhim kho cov cuab yeej los ua kom cov txheej txheem tau raug xa mus kom haum rau kev hloov kho ntawm qhov tseeb thiab tsis muaj qhov yuam kev worktable, txhawm rau txhawm rau tshem tawm qhov sib xyaw ua ke ntawm ntau yam tsis raug.
