Magnetic couplings asiri ekubatana anoshandisa magineti kuendesa torque, simba kana kufamba kubva kune imwe nhengo inotenderera ichienda kune imwe. Kuchinjisa kunoitika kuburikidza neasiri-magineti gineti yekuvharira pasina chero chemuviri kubatana. Iwo akabatanidzwa anopokana maviri emadhisiki kana rotor akaiswa nemagineti.
Kushandiswa kwemagineti coupling kunodzokera kune kwakabudirira kuyedza naNikola Tesla mukupera kwezana ramakore re19. Tesla akabatidza marambi asina waya achishandisa pedyo-munda resonant inductive coupling. Nyanzvi yefizikisi yekuScotland uye injiniya Sir Alfred Ewing akaenderera mberi nedzidziso yemagnetic induction mukutanga kwezana ramakore rechi20. Izvi zvakakonzera kugadzirwa kwehuwandu hwetekinoroji vachishandisa magineti coupling. Magnetic couplings mumashandisirwo anoda kunyatsojeka uye kwakasimba kushanda kwakaitika muhafu yekupedzisira yezana ramakore. Kukura kwemaitiro ekugadzira epamberi uye kuwedzera kuwanikwa kwezvinhu zvisingawanzo pasi magineti zvinoita kuti izvi zvigoneke.
Nepo ese magineti couplings anoshandisa magineti akafanana uye magineti ekutanga masimba, kune marudzi maviri anosiyana nekugadzira.
Mhando mbiri huru dzinosanganisira:
-Disc-mhando macouplings ane maviri akatarisana-kutarisana-disiki mahafu akamisikidzwa aine akatevedzana magineti uko torque inotamiswa pane gap kubva kune rimwe dhisiki kuenda kune rimwe.
-Synchronous-type couplings akadai seanogara magineti couplings, coaxial couplings uye rotor couplings uko rotor yemukati inoiswa mukati meiyo yekunze rotor uye magineti echigarire anotamisa torque kubva kune imwe rotor kuenda kune imwe.
Pamusoro pemhando mbiri huru, magineti couplings anosanganisira spherical, eccentric, spiral uye nonlinear dhizaini. Aya magineti ekubatanidza mamwe anobatsira mukushandiswa kwe torque uye vibration, yakanyatso shandiswa mukunyorera biology, chemistry, quantum mechanics, uye hydraulics.
Nemashoko akareruka, magineti couplings anoshanda achishandisa pfungwa yakakosha iyo inotarisana nemagineti pole inokwezva. Kukwezva kwemagineti kunoendesa torque kubva kune imwe magnetized hub kuenda kune imwe (kubva kune inotyaira nhengo yekubatanidza kune inotyairwa nhengo). Torque inotsanangura simba rinotenderedza chinhu. Sezvo ekunze angular kumhanya ichiiswa kune imwe magineti hub, inotyaira imwe yacho nekufambisa torque zvine magineti pakati penzvimbo kana kuburikidza neasiri-magineti inodzivirira senge madziro anopatsanura.
Huwandu hwe torque inogadzirwa neichi chiitiko chinotemwa nemhando dzakadai se:
-Kushanda tembiricha
-Nzvimbo umo kugadzirisa kunoitika
- Magnetic polarization
-Nhamba yemapuranga maviri
- Zviyero zvepairi mapairi, kusanganisira gap, dhayamita uye kureba
-Relative angular offset yevaviri
-Kuchinja kwezviviri
Zvichienderana nekurongeka kwemagineti uye madhisiki kana rotor, iyo magineti polarization ndeye radial, tangential kana axial. Torque inobva yaendeswa kune imwe kana kupfuura zvikamu zvinofamba.
Magnetic couplings anoonekwa seakakwirira kune echinyakare mechanical couplings munzira dzinoverengeka.
Kushaikwa kwekubatana nezvikamu zvinofamba:
-Inoderedza kupokana
-Inoburitsa kupisa kushoma
-Inoita kushandiswa kwakanyanya kwesimba rinogadzirwa
-Zvinokonzera kusapfeka uye kubvaruka
-Inoita hapana ruzha
-Inobvisa kudiwa kwekuzora
Pamusoro pezvo, iyo yakavharirwa dhizaini yakabatana nemhando dzakasiyana-siyana inobvumira magineti couplings kugadzirwa seguruva-proof, fluid-proof uye ngura-proof. Midziyo iyi inoshingirira mukuora uye inogadzirwa kuti ibate yakanyanyisa kushanda nharaunda. Imwe bhenefiti ndeye magineti breakaway chimiro chinomisikidza kuenderana kwekushandiswa munzvimbo dzine njodzi dzinogona kuitika. Uye zvakare, zvishandiso zvinoshandisa magineti couplings zvinodhura-zvinobudirira pane mechanical couplings kana iri munzvimbo dzine mashoma kuwana. Magnetic couplings isarudzo yakakurumbira yezvinangwa zvekuyedza uye kuisirwa kwenguva pfupi.
Magnetic couplings anoshanda zvakanyanya uye anoshanda kune akawanda epamusoro-pasi maapplication anosanganisira:
-Robhoti
-Chemical engineering
-Medical zviridzwa
-Kugadzwa kwemuchina
-Food processing
-Rotary michina
Parizvino, magineti couplings anokosheswa nekubudirira kwawo kana akanyudzwa mumvura. Mota dzakavharirwa mune isiri-magnetic barriers mukati memvura pombi uye propeller masisitimu inobvumira simba remagineti kuti rishandise propeller kana zvikamu zvepombi zvakasangana nemvura. Kukundikana kweshaft yemvura kunokonzerwa nekupindirwa kwemvura mudzimba dzemota kunodzivirirwa nekutenderedza seti yemagineti mumudziyo wakavharwa.
Zvishandiso zvepasi pemvura zvinosanganisira:
-Diver propulsion mota
-Aquarium pombi
-Mota dzepasi pemvura dzinoshandiswa kure
Sezvo tekinoroji ichivandudza, magineti couplings anowedzera kuwanda sekutsinhana kwekumhanyisa dhiraivha mumapombi uye fan motors. Muenzaniso wekushandiswa kwakakosha kwemaindasitiri mamotor mukati mematurbine makuru emhepo.
Huwandu, saizi uye rudzi rwemagineti anoshandiswa mukubatanidza sisitimu pamwe neinoenderana torque inogadzirwa zvakakosha zvakatemwa.
Zvimwe zvinotsanangurwa zvinosanganisira:
-Kuvapo kwechipingamupinyi pakati pemagineti pairs, chinokodzera midziyo yekunyudzwa mumvura.
- Iyo magnetic polarization
-Nhamba yezvikamu zvinofamba torque inotamiswa magnetically
Iwo magineti anoshandiswa mumagineti couplings anoumba zvisingawanzo pasi zvinhu senge neodymium iron boron kana samarium cobalt. Zvipingamupinyi zviripo pakati pemagineti pairs zvakagadzirwa nezvinhu zvisiri-magnetic. Mienzaniso yezvinhu zvisina kukwezvwa nemagineti isimbi isina tsvina, titanium, plastiki, girazi nefiberglass. Izvo zvasara zvezvikamu zvakanamirwa kune chero divi remagineti couplings zvakafanana neaya anoshandiswa mune chero sisitimu ine echinyakare mechanical couplings.
Iyo chaiyo magineti coupling inofanirwa kusangana neinodiwa nhanho ye torque yakatsanangurwa kune yakarongwa kushanda. Kare, kusimba kwemagineti ndiko kwaitadzisa. Nekudaro, kuwanikwa uye kuwedzera kuwanikwa kwemagineti akasarudzika epasi kuri kukurumidza kukura kugona kwemagineti couplings.
Chechipiri chekutarisa kukosha kwekubatanidzwa kunyudzwa zvishoma kana kuti zvachose mumvura kana mamwe marudzi emvura. Magnetic coupling vagadziri vanopa masevhisi ekugadzirisa kune akasiyana uye akatarisana zvinodiwa.
