Mazuvano, mumabhebhi edu, zvakajairika kurodha ma stepper motors ane axis yakafanana neaxis yavo-kunyanya patinoabatanidza kune lead screws kana worm gears.Nehurombo, ma stepper motors haanyatso kushandiswa kune rudzi urwu rwemutoro, uye kuita kudaro nesimba rakawanda kunokuvadza mota.Asi usatya.Kana iwe ukazviwana uri mumamiriro ezvinhu aya, [Voind Robot] inokupa iwe yakapusa asi inoshanda kwazvo kusimudzira mhinduro inobvumira yako stepper mota kubata axial mitoro pasina matambudziko.
Panyaya ye [Voind Robot's], vakatanga neiyo worm gear drive parobhoti ruoko.Muchiitiko chavo, ruoko runofamba runogona kuisa mutoro muhombe weaxial padanho rinopfuura nemuhonye—kusvika ku30 Newtons.Mutoro wakadaro unogona kukuvadza zviri nyore mukati meiyo stepper mota munguva pfupi, saka vakasarudza kumwe kusimbiswa kwemativi maviri.Kuti chinetso ichi chipere, mathrust bearings maviri akaunzwa, imwe kudivi rimwe nerimwe remugero.Basa rema thrust bearings aya ndere kuendesa simba kubva kushaft kuenda kune mota imba, inova nzvimbo yakasimba yekuisa mutoro uyu.
Iyi nzira iri nyore kwazvo, chaizvoizvo yave inopfuura makore mashanu.Zvakangodaro, zvichiri kukosha nhasi kune chero 3D printer mugadziri achifunga kubatanidza lead screw kune Z-axis stepper mota.Ikoko, kurovera kumwe chete kunogona kubvisa chero axial kutamba uye kukonzeresa kuvakwa kwakaomarara.Isu tinoda nyore muchina kugadzira huchenjeri seizvi.Kana iwe uchitsvaga mamwe matipi edhizaini edhizaini, tarisa [Moritz's] Workhorse Printer chinyorwa.
Hongu, makore mashoma apfuura ndakagadzira i3 musiyano printa inonzi i2 Samuel.Yakagadzirwa ine thrust inotakura pa z kubvisa kudzvanywa pane inotsika
Iyo inotenderwa axial mutoro weakawanda stepper motors haipfuure uremu * g.Kana zvakanyanya, dhizaini yako haina kukanganisa kana kuti inoshamisa, uye iyi inowanzova yekutanga.
pfungwa yakanaka.Nenzira, pane munhu angandiudza kwandingatenga mabearings madiki?Ndine akati wandei mafeni mafani ane Doom ™ rumble, asi ivo vachiri kushanda.
"Uchenjeri uhwu huri nyore, hwave hunopfuura makore mashanu."Hongu, ndinobvuma kuti kusimudzira kwakagadzirwa makore anopfuura mashanu apfuura.
Stepper motors dzinowanzoita seine imwe dhigirii yeaxial inoyangarara mugomba uye inogadziriswa nematsutso emvura.Izvi ndezvekuchengetedza axial mutoro pakutakura mukati meiyo yakatarwa kana mota ichipisa uye kwakasiyana kuwedzera kwemafuta kunoitika.Kurongeka kunoratidzwa pano hakupi kuwedzera kwemafuta, saka panogona kunge paine matambudziko enguva refu nemabhengi emota.Kuvapo kana kusavapo kuchaenderana nenzvimbo yeshaft iyo iyo thrust bear yakaiswa.Nenzira yakanaka, iyo yekusimudza mudziyo yese ichave iri kune imwe mugumo, uye imwe mugumo ichayangarara zvakasununguka sezvo chikamu chinowedzera.Muchokwadi, zvakanakisa kungoisa iyo thrust bearing painobuda kumagumo, padyo sezvinobvira kune inobuda inotakura, uye kuvimba neiyo yepakutanga inoburitsa inotakura kudzora kupinza munzira kunze kwemota.Tichifunga (yekuratidzira) 604 inotakura ine 4mm shaft (panzvimbo yeNema23′s 6mm shaft), ipapo iyo radial radial mutoro ndeye 360N uye iyo yakatemerwa axial mutoro ndeye 0.25 nguva (0.5 nguva yemabhengi makuru).Saka iyo inobuda inopera Iyo yepakutanga yakadzika groove bhora inofanira kushanda, ine axial load ye90N.Mumuenzaniso wakapihwa (30N), maererano nehupenyu hwekubereka, hazviratidzike kunge zvine hanya.Nekudaro, iyo axial inoyangarara mushaft ichitarisana nechitubu chakaremerwa ingangoda kugadziriswa, uye kamwechete kanosimudzira kumagumo kunobuda kunogona kuita izvi.
Nekudaro, zviri nani kushongedza honye neyakasiyana seti yekukanda mabearings uye kubvumira mota yese kuti iyangamire axially ine yakakodzera torque reaction mudziyo.Uku kurongeka kwakajairwa umo mota inotyaira bhora sikururu neayo angular yekubata inotakura yakaiswa kuburikidza neLovejoy kana yakafanana coupling.Nekudaro, izvi zvinowedzera hurefu hwakawedzerwa.
Andy, ini ndichanyora chinhu chimwe chete: Anoita seakawedzera mabheya pasina mapeji, achingotarisira kuti mabheji akakodzera anogona kumira mutoro.
Ndiyo ndima yekupedzisira.Kunze kwekunge tapered roller bearings kana angular contact ball bearings kana akaparadzana thrust bearings anoshandiswa, mota haifanire kutakura hombe axial mutoro pashaft yayo.
Iyo mota inofanirwa kutyaira shaft kuburikidza nebhandi, giya, elastic coupling kana spline coupling.Iyo yakakura kuomarara kwekubatanidza, kunowedzera kurongeka kwezvinodiwa zvemota yekumisikidza shaft.
Bvumiranai, kurongeka kwakasarudzwa pano kunogona kutokuvadza hupenyu hwesevhisi yemota.Mabhora ebhora emota pachayo anogona kunge achiri kutakura mutoro wakakura.Mufananidzo wacho unoratidzika kuratidza nzvimbo yakakwana yekutsigira gonye.Kusarudza kutsigira gonye ne 2 angular yekubata mabearings kumagumo ese uye kuityaira kuburikidza ne spline shaft kana kiyi shaft yatove sarudzo iri nani, IMHO.Iyo inochinjika yekubatanidza pakati ndiyo imwe kuvandudzwa kwairi.
Usati wabata chitubu washer kuzasi, iyo ime stepper haizonyatso kutakura chero axial mutoro, shaft uye kutakura zviri mukutsvedza.
Zvinobva pane stepper.Ini ndaona zvakare kuti kana mawashi echitubu akamanikidzwa kureba, imwe kana kunyange ese maviri mabheji ayo anotakura axial mutoro.
Saka sezvandakataura, chero ukasadzika pasi chitubu washer, hapazove neakawandisa axial mutoro pakutakura.
Hongu, asi aya mawashi echitubu anowanzo kushaya simba, saka mumashandisirwo akadai, unogona kudzika pasi nyore nyore.
@ThisGuy Iyi ndiyo kiyi yekukanda mabearings, vanokiya rotor pakati, saka mawashi echirimo haazomboshanda.
Ndinoziva kuti zvese zvine hukama, asi ini handigone kubatsira asi kuwana kuwedzeredza pano kunonakidza-mune imwe tsika yechinyakare, "hombe axial mutoro weinodarika mapaundi matanhatu"
Iyi isarudzo yakaipa.Roller bearings inoshanda nemazvo nekuti inoderedza kukweshana nekukunguruka pachinzvimbo chekukweva-dambudziko riripo netsono roller thrust bearings nderekuti kupera kwetsono pa o/d kunofamba nekukurumidza kupfuura i/d (kunze kwekunge tsono yadzipwa) Hongu, nokuti maapplication mazhinji, hapana anofunga).Hongu kune tapered tsono roller thrust bearings, asi mukomana uyu ari nani kushandisa spherical thrust bearings panzvimbo-iye haana muganhu pane axial mutoro kusvikira kutakura kuputika kana gasket yakadzimwa, kana izvi zvichapfuura mapaundi matanhatu.
Pamusoro pezvo, mushure mekuisa preload yakakodzera pane spherical thrust bearing, anenge asina radial resistance.Pfungwa yakanaka, mamwe maonero enyanzvi angadai akashandiswa.
Hupenzi hwangu, maonero angu ndeekuti akashandisa mabheji etsono akatwasuka, asi mijaho yepakati hairatidzike sezvikamu.
Ini ndinoda kukurukura ese akasiyana magadzirirwo ekutakura uye zvigadziriso, uye ini ndinoda nhevedzano yezvinyorwa zvinofukidza tapered rollers uye tapered thrust mabearings mumienzaniso chaiyo yekugadzira.Inondiyeuchidza lathe yandiri kugadzira.
Kubva pamufananidzo, kana zvichibvira, ndaizoisa chitsigiro pamagumo eshaft ye stepper.Mazhinji ekupfeka uye mativi ekutakura masimba anogona kubatwa zvirinani nerutsigiro pachinzvimbo chepamusoro lateral deflection.
Kubvumirana nezvakataurwa nezve tapered roller bearings, iyo lathe spindle inoashandisa ari maviri akaremerwa kumberi nekuti akagadzirwa kuti amire ese axial uye lateral mitoro, sezvinoita giya rehonye pano.
Vanogona here kushandisa servo flexible coupling, spider coupling, kana pramu coupling kupatsanura shaft ye stepper motor kubva kune shaft inotyaira giya rehonye?Handina chokwadi nezve torsional mutoro wavari kubata nawo.Kana pamwe giya 1: 1?
Ipapo ivo vanogona kutungamira simba mukati memota inokwirisa furemu neinenge isina simba kune stepper shaft.
Iwe unofanirwa kushandisa mabearings anogona kugamuchira zvinotarisirwa zvinorema (angular kubata, taper, thrust, nezvimwewo), nemabhora kana trapezoidal screws chero zvakadaro.Mota mabearings kazhinji haagone kumira mitoro yakadaro, uye kutadza kunyatso tsigira screw kuchave nemhedzisiro yakaipa pakurongeka.Sezvineiwo, iyo screw positioning musangano ndeye 100% yekuzvitsigira, hapana chikonzero chekubatanidza kune mota, mota inongopa torque.Ndiyo Machine Dhizaini 101. Kana mutoro uri mukati meiyo yakatarwa, unogona kusiya iyo inosimudzira inotakura, asi kazhinji itsika yakaipa kuita kudaro, nekuti iyo inopinza mutoro inogona kuita kuti zvikamu zvemukati zvemotor zvisarudzwe, zvichikanganisa mashandiro. .Ingotarisa chero yakajairwa bhora rinotakura uye tarisa inogamuchirika svutugadzike mutoro, unogona chaizvo kushamisika kuti idiki sei iyo yakatemerwa thrust mutoro muzviitiko zvakawanda.
Sezvo pasina bhatani rekugadzirisa, ini ndakawedzerawo kuti kazhinji, zvichienderana nehuwandu hwekurongeka kwaunoda, giya rehonye rinoshandiswa kune zvese zvinangwa uye zvinangwa zvinogona kutorwa semabhora kana conical screws, nekuti mauto anenge ari munzira imwe chete. .
Kuremerwa pagiya rehonye kwakasiyana zvakanyanya nemutoro uri paAcme kana bhora screw.Sezvo Acme uye bhora screws anoshandiswa neazere nzungu, mutoro wacho unenge wakangoita axial.Gonye rinongoshanda pagiya kune rimwe divi, saka kune radial load.
Ini ndichaenda neimwe nzira, uye vanhu vazhinji vanozoshamisika kuona kuti yakakura sei axial mutoro wekutakura bhora.Kanenge 25% radial mutoro, 50% inorema chikamu / yakakura kubereka.
Chero zvazvingava, kana usinganetse kupfupisa hupenyu hwekubereka uye kutadza kungaita njodzi, ndapota ramba uchishandisa mabheji ebhora kubata zvinorema!FWIW, kana iyo yakajairwa bhora inotakura mutoro wekukanda, nzvimbo yekubata inodzikiswa zvakanyanya.Kana hukuru hwekutakura hwakakura zvakakwana, iwe unogona kusaona chero chinhu chakakomba kana chine ngozi, asi izvi hazvifananidzi, kunyanya kana zvikamu zvako "zvakachipa".
Zvino iwe watosiyana nazvo.Kana mugadziri anotakura akati inokodzera radial mutoro we x Newton, ndiko kutsanangurwa.
Nhamba dzangu dzakabva paSKF online guide.Vanogona kuziva nzvimbo yavo zviri nani kupfuura iwe.Kana ukada nharo dzisina kurongeka: mavhiri emudhudhudhu mabhora maviri akadzika groove, anoona masimba kumativi ese zvisina tsarukano, uye anogona kushandiswa kwenguva yakareba.Ndakatyaira angangoita 120,000 mamaira muyedzo yangu.
Iyo yakasarudzika "kubereka bhora" ibhora rakadzika groove.Kana isiri chimwe chinhu, ibhora rakadzika groove.Ona zvikamu pano.https://simplybearings.co.uk/shop/Products-All-Bearings/c4747_4514/index.html
