Hal-abuurka iyo kobcinta mashiinka dhalo samaynta ee go'aamiya IS
Horraantii 1920-meeyadii, kii ka horreeyay ee shirkadda Buch Emhart ee Hartford waxa uu ku dhashay mashiinka samaynta dhalada ee ugu horreeya (Qaybta Shakhsiga), kaas oo loo qaybiyay dhawr kooxood oo madaxbannaan, koox kastaa waxay joojin kartaa oo beddeli kartaa caaryada si madax-bannaan, iyo hawlgalka iyo maamulka waa mid aad u habboon.Waa afar qaybood oo IS ah mashiinka samaynta dhalada.Codsiga rukhsadda waxaa la xareeyay Agoosto 30, 1924, lamana ogolaan ilaa Febraayo 2, 1932.Ka dib markii moodelku uu ku baxay iib ganacsi 1927, wuxuu helay caannimo baahsan.
Tan iyo markii la alifay tareenka iskiis u shaqeya, waxa uu soo maray saddex marxaladood oo tignoolajiyadeed: (3 Xilliyada Tignoolajiyada ilaa hadda)
1 Horumarinta mashiinka darajada makaanikada IS
Taariikhda dheer ee laga soo bilaabo 1925 ilaa 1985, mishiinka mashiinka samaynta nooca safafka ah wuxuu ahaa mishiinka ugu muhiimsan warshadaha dhalada.Waa durbaan makaanik ah/muraash dhululubo oof-wareen ah (Durbaanka waqtiga/dhaqdhaqaaqa oof-wareenka).
Marka durbaanka farsamaysan la isku beego, marka uu durbaanku wareego badhanka waalka ee durbaanka waxa uu wadaa furitaanka iyo xidhidhiyaha waalka ee Mechanical Valve Block, iyo hawada cufan ayaa kaxaysa dhululubo (Silinder) si ay u celiso.Ficilka ka dhig mid u dhammaystiran si waafaqsan habka samaynta.
2 1980-2016 Present (maanta), tareenka wakhtiga elektiroonigga ah AIS (Qaybta Shakhsi ahaaneed ee faa'iidada), xakamaynta wakhtiga elektiroonigga ah / wadista dhululubada pneumatic (Xakamaynta korantada / Dhaqdhaqaaqa Pneumatic) ayaa la alifay oo si degdeg ah loo geliyay wax soo saarka.
Waxay isticmaashaa tignoolajiyada microelectronic si ay u maamusho ficilada samaynta sida samaynta dhalada iyo wakhtiga.Marka hore, signalka korontadu waxa uu koontaroolaa waalka solenoid-ka (Solenoid) si uu u helo fal koronto, qadar yar oo hawo ah oo ciriiri ah ayaa soo marta furitaanka iyo xiritaanka valve solenoid, waxayna isticmaashaa gaaskan si ay u maamusho waalka gacanta (Cartridge).Ka dibna xakamee dhaqdhaqaaqa telescopic ee dhululubada wadista.Yacni waxa loogu yeero koronto ayaa maamula hawada bakhaylka ah, hawada bakhaylkuna waxay maamusho jawiga.Sida xogta korantada, signalka korantada waa la koobi karayn karaa, la kaydin karaa, la isku xidhi karaa oo waa la isweydaarsan karaa.Sidaa darteed, muuqaalka mashiinka wakhtiga elektiroonigga ah ee AIS wuxuu keenay taxane cusub oo cusub mashiinka samaynta dhalada.
Waqtigan xaadirka ah, inta badan dhalada dhalada iyo warshaddaha gudaha iyo dibaddaba waxay isticmaalaan mashiinka noocaan ah ee dhalada.
3 2010-2016, mashiinka safka buuxa ee NIS, (Heerka Cusub, Xakamaynta Korontada/Motion Servo).Matoorada Servo waxa loo isticmaalay mishiinada samaynta dhalada ilaa 2000. Waxa markii ugu horaysay loo adeegsaday furitaanka iyo xidhitaanka dhalooyinka mishiinka samaynta dhalada.Mabda'a ayaa ah in calaamadda microelectronic lagu kordhiyo wareegga si toos ah loo xakameeyo loona wado ficilka matoorka servo.
Maaddaama matoorka servo uusan lahayn wadista pneumatic, waxay leedahay faa'iidooyinka isticmaalka tamarta hooseeya, buuq la'aan iyo xakameyn habboon.Hadda waxay u soo baxday mashiinka samaynta dhalada servo oo buuxa.Si kastaba ha noqotee, iyada oo la tixgelinayo xaqiiqda ah in aysan jirin warshado badan oo isticmaalaya mashiinnada dhalada dhalada ee buuxa ee Shiinaha, waxaan soo bandhigi doonaa kuwan soo socda iyadoo loo eegayo aqoontayda hoose:
Taariikhda iyo Horumarinta ee Servo Motors
Bartamihii ilaa dabayaaqadii 1980-aadkii, shirkadaha waaweyn ee adduunku waxay lahaayeen noocyo kala duwan oo badeecooyin ah.Sidaa darteed, matoorka servo-ga ayaa si xoog leh loo dalacsiiyay, waxaana jira goobo badan oo codsiga ah ee matoorka servo.Ilaa iyo inta ay jirto ilo koronto, oo ay jirto shuruud sax ah, waxay guud ahaan ku lug yeelan kartaa matoorka servo.Sida qalabyada kala duwan ee mishiinada, qalabka daabacaadda, qalabka wax lagu duubo, qalabka dharka, qalabka laser, robots, khadadka wax soo saarka ee kala duwan iyo wixii la mid ah.Qalabka u baahan saxnaanta hab-socodka xad sare, hufnaanta hab-socodka iyo isku halaynta shaqada ayaa la isticmaali karaa.Labaatankii sano ee la soo dhaafay, shirkadaha soo saara dhalooyinka ajnabiga ah ayaa sidoo kale qaatay matoorada servo ee mashiinnada samaynta dhalada, waxaana si guul leh loogu isticmaalay khadka wax soo saarka dhabta ah ee dhalooyinka dhalooyinka.tusaale.
Halabuurka mashiinka servo
Darawal
Ujeedada shaqada ee servo drive waxay inta badan ku saleysan tahay tilmaamaha (P, V, T) ee uu soo saaro kantaroolaha sare.
Matoorka servo waa inuu lahaadaa darawal si uu u wareego.Guud ahaan, waxaan u yeernaa servo motor uu ku jiro darawalkiisa.Waxay ka kooban tahay matoorka servo oo ku habboon darawalka.Habka guud ee AC servo motor darawalka habka loo xakameeyo guud ahaan waxaa loo qaybiyaa saddex habab: booska servo (P Command), xawaaraha servo (V Command), iyo torque servo (T Command).Hababka xakamaynta ee caadiga ah waa booska servo iyo xawaaraha servo.Servo Motor
Istator-ka iyo rotor-ka matoorka servo waxay ka kooban yihiin birlab joogto ah ama gariiradaha xudunta u ah birta.Magnets-yada joogtada ahi waxa ay dhaliyaan goob birlabeed ah iyo gariiradaha xudunta u ah birta waxa ay sidoo kale dhalin doonaan goob birlabeed ah ka dib marka la tamarsiiyo.Is dhexgalka u dhexeeya stator magnetic field iyo rotor magnetic field wuxuu dhaliyaa qulqulka oo u wareego si uu u wado culeyska, si loogu wareejiyo tamarta korantada ee qaabka magnetka.Waxa loo beddelaa tamar makaanik, matoorka servo-ga waxa uu wareegaa marka ay jirto gelinta signalka kontoroolka, waxa uuna joogsadaa marka aysan jirin wax calaamad ah oo gelin.Beddelidda calaamadda xakamaynta iyo wajiga (ama polarity), xawaaraha iyo jihada matoorka servo waa la bedeli karaa.Rotor-ka gudaha matoorka servo waa magnet joogto ah.U/V/W saddex-waji koronto ah oo uu maamulo darawalku waxay sameeyaan goob elektromagnetic ah, rotorkuna wuxuu ku wareegayaa ficilka goobta magnetic. Isla mar ahaantaana, calaamadda jawaab celinta cod-bixiyaha ee la socda mashiinka ayaa loo diraa darawalka, iyo darawalku wuxuu isbarbar dhigayaa qiimaha jawaab celinta iyo qiimaha bartilmaameedka si loo hagaajiyo xagasha wareegga rotor-ka.Saxnaanta matoorka servo waxaa lagu go'aamiyaa saxnaanta cod-bixiyaha (tirada xadhkaha)
Codeeyaha
Ujeedada servo, encoder-ka ayaa si isku xiran loogu rakibay wax soo saarka mootada.Matoorka iyo codeeyaha si isku mid ah ayey u wada wareegaan, codeeyuhu sidoo kale wuu wareegaa mar uu matoorku wareego.Isla marka la wareego, signalka codeeyaha ayaa dib loogu soo celiyaa dirawalka, darawalkuna waxa uu qiimaynayaa in jihada, xawliga, booska, iwm. si waafaqsan. Encoder-ku wuxuu isku dhafan yahay mashiinka servo, waxaa lagu rakibay gudaha mashiinka servo
Nidaamka servo waa nidaam kontorool oo toos ah kaas oo awood u siinaya wax soo saarka tirada la xakameeyey sida booska, hanuuninta, iyo xaaladda shayga si ay u raacdo isbeddelada aan macquul ahayn ee bartilmaameedka wax-gelinta (ama qiimaha la bixiyay).Raadinta servo waxay inta badan ku tiirsan tahay garaaca wadnaha ee meelaynta, taas oo asal ahaan loo fahmi karo sida soo socota: matoorka servo wuxuu u rogi doonaa xagal u dhiganta garaaca wadnaha marka uu helo garaaca wadnaha, taas oo ogaanaysa barokac, sababtoo ah encoder ee matoorka servo sidoo kale wuu wareegayaa, iyo waxay awood u leedahay inay dirto Shaqada garaaca wadnaha, markaa mar kasta oo matoorku wareego xagal, waxay soo diri doontaa tiro u dhiganta garaaca wadnaha, taas oo ku celcelinaysa garaaca wadnaha ee servo, iyo isdhaafsiga macluumaadka iyo xogta, ama loop xiranImmisa garaac ayaa loo diraa matoorka servo, iyo inta garaac ee la helay isku mar, si wareegga mashiinka si sax ah loo xakameeyo, si loo gaaro meelaynta saxda ah.Ka bacdi, in muddo ah ayay wareegtaa iyadoo ay ugu wacan tahay firfircoonideeda gaarka ah, ka dibna way joogsan doontaa.Matoorka servo waa in uu istaago marka uu istaago, iyo inuu tago marka la yiraahdo tag, jawaabtuna waa mid aad u degdeg badan, mana jirto wax lumay oo tallaabo ah.Saxnimadiisu waxay gaari kartaa 0.001 mm.Isla mar ahaantaana, wakhtiga jawaab celinta firfircoon ee dardargelinta iyo dardargelinta matoorka servo sidoo kale waa mid aad u gaaban, guud ahaan gudaha tobanaan millise seconds (1 ilbiriqsi waxay u dhigantaa 1000 millise seconds) Waxaa jira macluumaad xiran oo u dhexeeya kontaroolaha servo iyo darawalka servo inta u dhaxaysa calaamada xakamaynta iyo warcelinta xogta, sidoo kale waxaa jira calaamada xakamaynta iyo jawaab celinta xogta (laga soo diray encoder) inta u dhaxaysa darawalka servo iyo servo motor, iyo macluumaadka u dhexeeya iyaga ayaa sameeya wareeg xiran.Sidaa darteed, saxnaanta isku xidhka xakamaynta ayaa aad u sareysa
