Ama-Coupling Magnetic ama-coupling angaxhunywanga asebenzisa inkambu kazibuthe ukuze adlulisele i-torque, amandla noma ukunyakaza ukusuka kwelinye ilungu elizungezayo ukuya kwelinye. Ukudlulisa kwenzeka ngesivimbelo esingenamagnetic ngaphandle kokuxhumana ngokomzimba. Ama-coupling amapheya aphikisanayo wamadiski noma ama-rotor ashumekwe ngozibuthe.
Ukusetshenziswa kokuhlanganiswa kazibuthe kubuyela emuva ekuhlolweni okuphumelelayo kukaNikola Tesla ngasekupheleni kwekhulu le-19. I-Tesla ikhanyisa izibani ngaphandle kwentambo isebenzisa i-near-field resonant inductive coupling. Isazi sefiziksi saseScotland kanye nonjiniyela uSir Alfred Ewing waqhubekisela phambili inkolelo-mbono yokungeniswa kazibuthe ekuqaleni kwekhulu lama-20. Lokhu kwaholela ekuthuthukisweni kwenani lobuchwepheshe obusebenzisa ukuhlanganisa kazibuthe. Ukuhlangana kwamagnetic ezinhlelweni ezidinga ukusebenza okunembe kakhulu nokuqine kakhulu kwenzeke engxenyeni yokugcina yekhulunyaka. Ukuvuthwa kwezinqubo ezithuthukisiwe zokukhiqiza kanye nokwanda kokutholakala kwezinto ezingavamile kazibuthe zomhlaba kwenza lokhu kwenzeke.
Nakuba wonke ama-coupling kazibuthe asebenzisa izici kazibuthe ezifanayo namandla emishini ayisisekelo, kunezinhlobo ezimbili ezihluke ngokuklama.
Izinhlobo ezimbili eziyinhloko zihlanganisa:
-Ama-couplings ohlobo lwediski anama-halves amabili obuso nobuso ashumekwe ngochungechunge lukamazibuthe lapho i-torque idluliselwa esikhaleni isuka kwelinye idiski iye kwelinye.
-Ukuhlangana kohlobo lwe-synchronous okufana nokuhlanganisa uzibuthe unomphela, ukuhlangana kwe-coaxial kanye nokuhlangana kwe-rotor lapho i-rotor yangaphakathi ifakwe ngaphakathi kwe-rotor yangaphandle kanye nozibuthe ongapheli udlulisela i-torque kusuka ku-rotor eyodwa kuya kwenye.
Ngaphezu kwezinhlobo ezimbili eziyinhloko, ukuhlanganisa kazibuthe kuhlanganisa imiklamo eyindilinga, eccentric, spiral kanye ne-nonlinear. Lezi zindlela zokuhlanganisa kazibuthe zisiza ekusetshenzisweni kwetorque nokudlidliza, ezisetshenziswa ngokukhethekile ezinhlelweni zokusebenza zebhayoloji, ikhemistri, i-quantum mechanics, nama-hydraulics.
Ngamagama alula, ukuhlanganisa kazibuthe kusebenza kusetshenziswa umqondo oyisisekelo oheha izigxobo eziphambene kazibuthe. Ukukhangwa kozibuthe kudlulisa i-torque kusuka kuhabhu enozibuthe kuya kwenye (kusuka elungeni elishayelayo lokuhlanganisa kuya elungeni elishayelwayo). I-torque ichaza amandla azungezisa into. Njengoba umfutho we-angular wangaphandle usetshenziswa kuhabhu kazibuthe eyodwa, ishayela enye ngokudlulisela i-torque ngozibuthe phakathi kwezikhala noma ngomgoqo wokuqukatha ongewona uzibuthe njengodonga oluhlukanisayo.
Inani le-torque elikhiqizwa yile nqubo linqunywa okuguquguqukayo okufana nalokhu:
-Izinga lokushisa lokusebenza
-Imvelo lapho ukucubungula kwenzeka khona
-I-polarization yamagnetic
-Inani lamapheya wezigxobo
-Ubukhulu bamapheya wezigxobo, okuhlanganisa igebe, ububanzi nobude
-Isihlobo esiyi-angular offset yamapheya
-Ukushintshana kwamapheya
Ngokuya ngokuqondana kwamazibuthe namadiski noma ama-rotor, i-polarization kazibuthe i-radial, tangential noma i-axial. I-torque ibe idluliselwa engxenyeni eyodwa noma ngaphezulu ezihambayo.
Ukuhlangana kwamagnetic kuthathwa njengokuphakeme kunokwendabuko ukuhlangana kwemishini ngezindlela eziningi.
Ukuntuleka kokuxhumana nezingxenye ezihambayo:
-Yehlisa ukungqubuzana
-Ikhiqiza ukushisa okuncane
-Usebenzisa amandla akhiqiziwe kakhulu
-Iphumela ekugugeni kancane
-Ayikhiqizi umsindo
-Iqeda isidingo sokuthambisa
Ukwengeza, idizayini evalekile ehlotshaniswa nezinhlobo ezithile ezivumelanayo ivumela ukuhlangana kazibuthe ukuthi kwenziwe njengokuvikela uthuli, uketshezi olungenamanzi kanye nokugqwala. Amadivayisi awakwazi ukugqwala futhi akhelwe ukuphatha izindawo zokusebenza ezidlulele. Enye inzuzo isici esinqamuka kazibuthe esisungula ukuhambisana ukuze sisetshenziswe ezindaweni ezinezingozi zomthelela ezingaba khona. Ukwengeza, amadivaysi asebenzisa ama-coupling kazibuthe abiza kakhulu kunokuhlanganiswa kwemishini lapho etholakala ezindaweni ezinomkhawulo wokufinyelela. Ukuhlanganisa kazibuthe kuyinketho edumile ngezinjongo zokuhlola nokufakwa kwesikhashana.
Ukuhlanganisa kazibuthe kusebenza kahle kakhulu futhi kuyasebenza ezinhlelweni eziningi ezingaphezulu komhlaba ezihlanganisa:
- Amarobhothi
- Ubunjiniyela bamakhemikhali
-Izinsimbi zokwelapha
-Ukufakwa komshini
-Ukulungiswa kokudla
- Imishini yokujikeleza
Njengamanje, ama-coupling kazibuthe ayaziswa ngokusebenza kwawo lapho ecwiliswa emanzini. Amamotho avalelwe kusithiyo esingewona uzibuthe ngaphakathi kwamaphampu awuketshezi namasistimu ophephela avumela amandla kazibuthe ukuthi asebenzise uphephela noma izingxenye zepompo ezithinta uketshezi. Ukwehluleka kweshafu yamanzi okubangelwa ukungena kwamanzi endlini yenjini kugwenywa ngokuphotha isethi yomazibuthe esitsheni esivaliwe.
Izicelo zangaphansi kwamanzi zihlanganisa:
- Izimoto ezihamba nge-Diver
- Amaphampu e-aquarium
-Izimoto zangaphansi kwamanzi ezisebenza ukude
Njengoba ubuchwepheshe buthuthuka, ama-coupling kazibuthe avame kakhulu njengokuthatha indawo yesivinini esishintshashintshayo kumaphampu nama-fan motors. Isibonelo sokusetshenziswa okubalulekile kwezimboni amamotho angaphakathi kwezinjini zomoya ezinkulu.
Inombolo, usayizi kanye nohlobo lukazibuthe olusetshenziswa ohlelweni lokuhlanganisa kanye ne-torque ehambisanayo ekhiqizwayo kuyizici ezibalulekile.
Eminye imininingwane ihlanganisa:
-Ukuba khona kwesithiyo phakathi kwamapheya kazibuthe, okwenza amathuluzi afanelekele ukucwiliswa emanzini
- I-polarization kazibuthe
-Inombolo ye-torque yezingxenye ezihambayo idluliselwa ngozibuthe
Ozibuthe abasetshenziswa ekuhlanganiseni kazibuthe bahlanganisa izinto zomhlaba ezingavamile njenge-neodymium iron boron noma i-samarium cobalt. Izithiyo ezikhona phakathi kwamapheya kazibuthe zenziwe ngezinto ezingezona uzibuthe. Izibonelo zezinto ezingadonswa ngozibuthe yinsimbi engagqwali, i-titanium, ipulasitiki, ingilazi ne-fiberglass. Ingxenye esele yezingxenye enamathiselwe kuzo zombili izinhlangothi zokuhlangana kazibuthe iyafana naleyo esetshenziswa kunoma iyiphi isistimu enokuhlangana komshini okuvamile.
Ukuhlanganisa kazibuthe okulungile kufanele kuhlangabezane nezinga elidingekayo letorque elicaciswe umsebenzi ohlosiwe. Esikhathini esidlule, amandla kazibuthe kwakuyisici esinciphisayo. Kodwa-ke, ukutholakala nokwanda kokutholakala kwezibuthe ezikhethekile zomhlaba ezingavamile amandla akhula ngokushesha okuhlangana kazibuthe.
Ukucatshangelwa kwesibili yisidingo sokuthi ama-coupling acwiliswe kancane noma ngokuphelele emanzini noma kwezinye izinhlobo zoketshezi. Abakhiqizi bokuhlanganisa kazibuthe bahlinzeka ngezinsizakalo zokwenza ngokwezifiso izidingo eziyingqayizivele nezigxilile.
