Encoder - isifaki khodi yokwanda kuyinto ...

Igama elithi "I-encoder" ine imvelaphi ngesiNgisi. It livela izwi encode, ukuthi kusho ukuthini "uguqule." Abenzi kunazo owaziwa international amadivayisi brand owaziwa ezifana Siemens, SKB, HEIDENHAIN RLS Baumer, ABAGULAYO AG, Balluff, Schneider kagesi (Autonics Telemecanique), OMRON.

Ububanzi kwesicelo nenjongo

Encoder - Inzwa isetshenziswa emkhakheni ezimbonini yokuguqula ubuningi elawulwa ku isignali kagesi. Ukusebenzisa kunqunywa, isibonelo, isikhundla oluthi motor kagesi. Ngenxa yokuthi idivayisi ngalinye, okuyinto iqasha ligijima, kumele ifakwe idivayisi, ukunemba ukulawula torque izindawo ezidumile ukusetshenziswa transducers abanjalo bangabaphostoli esihle ukufuduka uhlelo. Injongo eyinhloko okuyiwona isifaki khodi isetshenziswa, - yokukala engela ukuzungeza into phakathi ukujikeleza. Kuzishumeki kubalulekile enqubeni ukukhiqizwa emshinini ithuluzi amabhizinisi, rabototehnicheskih izakhiwo. Basebenzisa nabo eziningi zanamuhla amadivayisi sokulinganisa, edinga yokubhaliswa ngokunemba nesilinganiso engeli ujikeleza, i-pan ne enyakazayo.

kuzishumeki simo

Zonke kuzishumeki eyaziwa njengamanje zihlukaniswe zokusebenza ngokuphelele futhi ekhuphukayo, Resistor, la mandla kazibuthe kanye optical ngokusebenzisa inethiwekhi ezimbonini noma ibhasi esibonakalayo.

Kuye isimiso esejwayelekile msebenzi angawodwa kuzishumeki ngokuphelele futhi ekhuphukayo. Umehluko emkhatsini izinhlobo ezimbili itholakala imisebenzi eyenziwa yibo. Uhlu imisebenzi ngesifaki khodi ngokuphelele kuyinto uhlu ubanzi kakhulu ihlanganisa isifaki khodi ekhuphukayo.

kuzishumeki ekhuphukayo

Lokhu isifaki khodi. Ngo inqubo ukushintshanisa into ku okhiqizwayo pulses benzelwe, inani okuyinto ngqo wakhona engela ukuzungeza into. Ngokuvamile, transducers ekhuphukayo asetshenziswa umshini amathuluzi ukuze ukubhalisa ukunyakaza emincane shaft noma izinhlelo ezenzakalelayo kumjikelezo impendulo ukukala nokuqopha isivinini kushaft ngokushintshana.

Encoder yokwanda - idivayisi isebenze ngesisekelo pulses eyenziwe idatha ngokushintshana. Isibalo pulses iyunithi kwegazi ngalinye - lena main yokusebenza ipharamitha zedivayisi. Inani lamanje ukutholwa inzwa-indlela Ubala pulses kusukela reference iphuzu. Ukuze ukuhlanganisa uxhumano nomsebenzisi ozimele ukusetha i-pulse isifaki khodi inkomba amamaki, okuyinto ziqala emva kokusebenzisa imishini. Ukunqunywa idatha usebenzisa i-transducer ekhuphukayo kungenzeka kuphela phakathi ukujikeleza noma kokuphenduka. Lapho ujikeleza wayeka zonke kabusha idatha isifaki khodi. Ngenxa yalokho, lapho ukuvula idatha counter odlule kuyoba engaziwa. Ukuze kube lula ukusebenza kwawo kushaft kufanele alethwe indawo yokuqala. isifaki khodi yokwanda ubhekana kahle umsebenzi ukulinganisa isivinini ujikeleza. Esebenzisa Ubala pulses kusukela uphawu kungaba azichaze ngokunembile njengoba wamanje Ukudidiyela ye-engeli ukujikeleza into.

kuzishumeki eliphelele

Lokho okubizwa ngokuthi i ngokuphelele isikhundla inzwa. kuzishumeki Ngokuvamile enjalo ebonwe okwengeziwe izinqubo eziyinkimbinkimbi signal processing electronic futhi has wesifunda optical. Kodwa ukunikeza imininingwane into ngokushesha nje ngemva ukuthi ngokuvamile kudingeka ukusebenza ngemfanelo kohlelo lonke. Eqhathaniswa nokusetshenziswa ekhuphukayo kuzishumeki ngokuphelele ongaxazulula ezahlukene ebanzi kakhulu imisebenzi, njengoba izilinganiso kusetshenziswa lock ishayela, namakhodi ekhethekile digital. Unit idivayisi efanayo - inombolo ehlukile amakhodi digital iyunithi ukujikeleza (1 ithuba). Ngenxa yokuthi wonke amakhodi digital okukhipha inzwa, esiyingqayizivele, ukucacisa zamanje Ukudidiyela ezinyakazayo komugqa ngokushesha ngemuva kokucima kudivayisi kulula futhi ngaphandle referetnoy ilebula. Ngesikhathi ikhodi kusebenze izinombolo liyavela ekhishwa inzwa. He is uphawu yesimo samanje ye-engeli ukuzungeza into. Ngakho, i-encoder ngokuphelele akugcini nje ubhekana nenkinga ethungatha ijubane ukujikeleza (ukuzungeza) ye-into, kodwa futhi ukhiqiza idatha elungile mayelana nendawo yayo ngqo nganoma isiphi isikhathi, noma ngabe exhunywe noma cha.

Izinhlobonhlobo kuzishumeki eliphelele

Kuye onezimfanelo ayusolyutnye kuzishumeki ingahluka yasibamba uhlobo, noma ukuba khona abayizimpumputhe, noma aphumele kushaft eziyize. Ububanzi amadivayisi enjalo futhi zahlukahlukene kakhulu ngokuya izici zangaphandle: ubude, ububanzi we umzimba nokunye. Ngaphezu kwalokho, kwaziwa ukuthi izinzwa ngokuphelele yokulinganisa izikhundla phakathi ukujikeleza multi-phenduka futhi single-turn khona. Actuators ukukhiqiza isikhundla wamanje ngaphakathi omunye inzuzo nonekhono nokuqonda multi rotations eziningana ezengeziwe.

isifaki khodi Optical - kuyini?

Le Converter is isandla ogibele idrayivu shaft, ezenziwe ngengilazi. Okufaka ikhodi optical, ngokungafani kuya izinzwa ezichazwe ngenhla, kuphinde ifakwe i rastorom optical okuyinto phezu ukujikeleza uhamba shaft futhi oguqula torque ku umfudlana ukukhanya ezitholwe photosensor kamuva.

Lolu hlobo lwe-Converter kuthola Ukujikeleza engeli, lapho isikhundla ngamunye esiyingqayizivele uhambelana ikhodi eyingqayizivele ekhethekile izinombolo. Yena, kanye nenombolo linemibhikisho futhi iyunithi yokukala inzwa. Ixhuma isifaki khodi futhi yayo yokusebenza isimiso ezifanayo ukusebenza ekhuphukayo zedivayisi kuchaziwe ngenhla.

Izinhlobo izinzwa kuncike isimiso yokusebenza

Izimfanelo kuzishumeki umsebenzi zihlukaniswe kazibuthe kanye Photoelectric.

Isimiso somzimba wokusebenza kusekelwe ukusetshenziswa lokuqala umphumela Hall, wathola ngo-1879 ngu E. Hall. Kulokhu, ezingaba umehluko kwenzeka kuphela uma ibekwe ku wire DC kazibuthe esifundeni.

Izimfanelo isixazululo kanye ukunemba magnetic isifaki khodi Photoelectric eliphansi, kodwa ekwenzeni lokho okuhleliwe kulula. He kude kancane izikhala nemibandela ukusebenza olindele.

Omele isifaki khodi kazibuthe umshini kuvikela loop edabula izingongolo kazibuthe kukazibuthe rotary, eduze isici inzwa. Isengezo idatha Lidlulisela futhi ine uhlobo ikhodi digital.

I Photoelectric isifaki khodi - uphenyo ukuthi usebenza ngesisekelo umphumela Photoelectric, okuyinto waphawula ngenxa yokuchayeka le ndaba. Kuphinde kuvule lesi simiso 1887 by H. Hertz. Ngo ukusebenza lolu hlobo inzwa waphawula ushintsho unomphela ugongolo ukukhanya ku isignali kagesi.

Zihambisana Photoelectric isifaki khodi optocoupler, optical futhi opto-elekthronikhi. Izinzwa yalolu hlobo bafuna ngaphezulu izici ukukhiqizwa, ukusebenza, futhi izinto eziningi ukwedlula abanye kuzishumeki, kodwa lokhu kuyafaneleka, ngoba ikhono zinembile lingaphezulu kakhulu kunalezo encintisana.
