Servo inotya - chii ichocho? Dhidhiyo, kuiswa uye kushandiswa kwemitemo ye servo drive

Vanhu vazhinji vanobvunza: servo - chii ichocho? Iyo yakasikwa yakarongeka ye servo drive inosanganisira motokari, chinzvimbo chemajeri uye matatu-loop control system (nzvimbo, kasi uye ikozvino kutonga).

Shoko rokuti "servo" rine chiLatini "servus", rinoshandurwa se "muranda", "mubatsiri", "muranda".

Muchikwata chekugadzira mishonga, zviyero zvakashanda sezvibatsiro zvekubatsira (feed drive mumushandisi, robot, nezvimwewo). Zvisinei, nhasi mamiriro ezvinhu akachinja, uye chinangwa chikuru che servo drive ndechokuita mumunda wevashumiri.

Kuisa servo drive kunonzwisisika apo vanhu vanowanzoshandura vatengesi vanodzora kusarurama kwekushanda kusina kukodzera.

Kushandiswa kwepamusoro-soro maikirwo anodiwa mune zvigadzirwa zvinoratidzwa nehupamhi hwekubudirira.

Nyaya iyi ichakuudza nezve servo drive, chii uye kuti inoshanda sei.

Nzvimbo dzekushandisa kwekushandisa

Munyika yemazuva ano, apo kushandiswa kwechigadziro kwakatora nzvimbo yakasimba munzvimbo dzose dzeunyanzvi, kuumbwa kwezvinhu zvose kwave kuonekwa zvakabatana. Panguva imwecheteyo, mazuva ano zvinotya zvinoshandiswa.

Kuti unzwisise servo, kuti chii, iwe unofanirwa kuziva rutivi rwechigadzirwa.

Zvirongwa izvi zvine zvakanyatsogadziriswa nekugadzirisa mafambiro emabhobhoti emabhizimisi nemashandisi emashandisi ane kukwirira kwakakwana. Izvo zvakasungirirwa pamusoro pekugadzira zvigadzirwa, mumitambo yakasiyana-siyana yekutakura uye nzira dzechibvumirano chechipiri.

Shanduro yakakura zvikuru yezvigadzirwa zvinowanikwa munzvimbo dzinotevera:

• Kugadzira mapepa nemapakiti;
• Kugadzirwa kwemashizha kubva kusimbi;
• Processing of materials;
• Kugadzirwa kwekutakura midziyo;
• Woodworking industry ;
• Kugadzira zvinhu zvekuvaka.

Servodrives padanda remotokari

Iko kune mhando dzakawanda dze servo dzinotungira turu yemotokari kubva kune vakasiyana-siyana. Funga nezvekushanda kwechigadziro chakadai semutanda we servo kubva kumudziri wekuumba Avtozebra. Chigadzirwa chacho chakagadzirirwa motokari yeRussia, asi kwete chete. Somuenzaniso, inogona kushandiswa mumotokari ye Renault Logan.

Maererano nemhinduro yevashandisi, izvi zvinogadzirwa zvakanaka. Inobvumira, pasina kusiya motokari, kuvhura uye kuvhara trunk.

Chigadzirwa chacho chinodzorwa nenzira yebhodhi yakakonzerwa mukati memotokari kana muvharo yekivha.

Chikonzero chekushandiswa kwakanyanya kwechigadzirwa

Chikonzero chekushandiswa kwemajaira evhavo ndeichi:

• Mikana yekuwana kutonga, iyo inoratidzika nekukwirira kwakakwana nekushanda kushanda;
• Wide range speed speed;
• High level of immunity to interference;
• Simba duku uye kuyerwa kwechigadzirwa.

Nheyo ye servo operation

Iyo chipfumi inoshanda sei? Servo, mutemo wekushanda unobva pane mhinduro kune imwe kana kupfuura zviratidzo zvese, inodzora chinhu chacho. Iko inobatsira kukosha kwechigadziro ichienda kune inowanikwa, apo kuenzaniswa nechiito chekugadzirisa kunoitika.

Zviratidzo zvemichina

Ivhariyo ye servo ine zvinhu zviviri zvinokosha:

• Mano ekuwedzera simba;
• Kugadziriswa kwehupombwe ruzivo.

Kugadziriswa kunodiwa kuitira chinangwa chokuti simba rinodiwa pane zvakabuda zvakanyanya kwazvo (rinobva kune imwe kunze chinyorwa), uye zvaro zvaro hazvikoshi pane zvayo.

Mhinduro haisi chinhu chinopfuura dunhu rine dunhu rakavharwa umo zviratidzo zvisingafananidzi paanowanikwa uye zvabuda. Izvi zvinoshandiswa kutungamira.

Kubva pano inotevera kupedzisa: mhirizhonga iri mberi inoshumira semhepo inopinza, uye nenzira yakatarisa ndiyo inotumira mashoko anonyanya kudiwa nekururama kwekutonga.

Simba uye kuvhara huni

Servo, mutemo wekushanda unoshandiswa mumagadzirirwo akaiswa paredhiyo, kazhinji ane mafaira matatu:

1. Chiratidzo. Icho chinoshandura kupora kwekuita. Kazhinji, tambo yakavezwa yakachena, yakatsvuka kana yakatsvuka.
2. Kudyisa. Chiratidzo chechigadziko chayo chinobva kune 4.8 kusvika ku6 V. Inowanzova tsvuku tsvuku.
3. Earthing. Tsanzu yakasviba kana yakaonda.

Kukura kwevashandi

Muhukuru, zvikamu zvakaparadzana zvikamu zvitatu:

• Microdrives;
• Standard modifications;
• Zvigadzirwa zvakakura.

Ikoko kune servos uye nezvimwe zviyero, zvisinei, zvinyorwa zviri pamusoro apa zvika 95% zvezviyero zvose.

Zvinonyanya kukosha zvechigadzirwa

Basa reServo rinoratidzwa nezviratidzo zviviri zvikuru: kukurumidza kwekuzungunuka uye simba riri mumumvuri. Nhamba yekutanga inoshanda sechiratidzo chenguva, iyo inoyerwa mumasekondi. Kuedza kuri kuyerwa mumakiromita / cm, ndiko kuti, ndeupi mukana wekuedza iyo inotangira kubva pakati pekushanduka.

Kazhinji, iyi parameter inobva pane chinangwa chikuru chechigadziro, uye chete ipapo pane nhamba yekutumirwa kwemugadziri uye zviyero zvinoshandiswa mumuchina.

Sezvatotaurwa, ikozvino inogadzira nzira dzinoshanda pamagetsi ekugadzirisa magetsi kubvira 4.8 kusvika ku6 V. Izvi zvinowanzoenzana ne6 V. Zvisinei, hazvisi zvose zvigadzirwa zvakagadzirirwa huwandu hwakawanda hwekudzivirira. Dzimwe nguva motokari ye servo inoshanda chete pa 4.8 V kana chete pa 6 V (iyo yekupedzisira kugadzirisa inonyanya kushandiswa).

Analog uye Digital Modifications

Makore mashoma apfuura, yese servos yaiva analog. Iye zvino panewo maumbirwo edijita. Ndeupi musiyano pakati pebasa ravo? Ngatitarisei nezvemashoko makuru.

Kubva mumushumo wekambani Futaba inotevera kuti mumakore gumi apfuura, zvinotungamirira zve servo zvakanyanya kuva nani kupfuura kare, pamwe nehukuru hukuru, hukuru hwekufambisa nekukurumidza uye nhamba yezvinhu zvekutambudza.

Chikamu chekupedzisira chekufambisa chiratidziro chechigadzirwa pane digital. Aya maumbirwo ane zvinyorwa zvakakosha kunyange pamberi pemotokari yemutori wechirwere. Kunyangwe pane zvimwe zvisingabatsiri.

Kunze kwekunze, zvigadzirwa zveanalogog uye zvejedi hazvisi pachena. Kusiyana kwakagadzirirwa chete pamabhodhi ekushandisa. Pachinzvimbo chechi chip pa digital unit, unogona kuona microprocessor ichiongorora chiratidzo chemugadziri. Anodzora injini.

Zvakakanganisika zvachose kutaura kuti analog uye digital kugadziriswa zvakasiyana zvakasiyana mukushanda kwavo. Vanogona kunge vane injini imwechete, maitiro uye zvinometers (zvinowirirana resistors).

Mhedzisiro huru ndiyo nzira yekugadzirisa chiratidzo chinouya chinogamuchira uye kugadzirisa motokari. Zvose zviri zviviri servo inotungamirira zviratidzo zvakafanana zveredhiyo.

Saka, inova pachena, servo, chii ichocho?

Nheyo yekushandiswa kweanorig modification

Muchidimbu chechirongwa chekufananidzira, chiratidzo chinogamuchirwa chinofananidzwa nechinzvimbo chemazuva ano che servomotor, uye ipapo chiratidzo chemugadziridziro chinoshandiswa kune motokari, zvichiita kuti motokari iende kune imwe nzvimbo yakagadziriswa. Iyi ndiyo minda yekupindura nguva. Kana iwe ukashandura chibato pamutambo, kuputika kwenguva pfupi kunotanga kushanda pane servo, kupera pakati pavo kuchaenzana ne20 m / sec. Hapana chinhu pakati pemafuta pamusoro pemotokari, uye kunze kwezvinhu zvinogona kuchinja kushanda kwechigadziro mune chero nzira. Nguva ino nguva inonzi "nzvimbo yakafa".

Nheyo yekushandiswa kwekugadzirwa kwedhidhiyo

Dhidhijhini majaira anoshandisa purogiramu inoshandiswa iyo inoshanda pamatunhu akakwirira. Inogadzirisa mucherechedzo uye inotumira kutora kwemajini kune injini nekupindurwa kazhinji kanomwe pamusi wechipiri. Sezvo chirevo chepurogiramu chakakwirira kwazvo, mhinduro yacho inokurumidza uye inochengetedza nzvimbo yacho zviri nani. Izvi zvinokonzera zvakanakisisa centering uye yakakwirira yekutambudzwa. Asi nzira iyi inoda simba rakawanda, saka bhatiri rinoshandiswa mumagetsi anogadziriswa rinozobudiswa nekukurumidza zvikuru mukugadzirwa uku.

Zvisinei, vese vashandisi vakambotarisana nedhijitori yemodhini vanoti kusiyana kwavo nekwakagadzirwa kweanalogo kwakanyanya kwazvo zvokuti havazombotashandisi zvakare.

Mhedziso

Chisarudzo chako chichava mifananidzo yemagetsi, kana uchida:

• High level of resolution ;
• Nhamba shoma ye "vakafa nzvimbo";
• Kunyatsogadzirisa nzvimbo;
• Kukurumidza kupindura kwechikwata;
• Kusanzwisiswa simba rinoshandiswa mubhandi paunotendeuka;
• High power level.

Iye zvino unoziva kuti servo chii uye kuti ungashandisa sei.
