Imininingwane Ebalulekile Yama-Neodymium Ring Magnets

Ngaphambi kokuba sihambe phansi efektri, ake siqonde into eyodwa. Awukwazi ukukhiqiza i-ring magnet ngendlela efanele uma imininingwane ifiphele.
Ukuchaza ubukhulu be-magnet yendandatho efanele yisihlungi sokuqala phakathi kwengxenye ewela eqoqweni lakho kanye nengxenye egobhozayo noma enyakazayo. Sizobuyela ekubekezeleni kamuva - kodwa yazi ukuthi isinyathelo ngasinye esingezansi sincike emdwebeni wakho.

 

Ukubuka konke kwenqubo yokukhiqiza i-Neodymium Ring Magnet

Ukulungiselela Izinto Ezibalulekile

Iqala nge-neodymium eluhlaza, insimbi, ne-boron – kanye nezinto ezimbalwa ezingeziwe njenge-dysprosium noma i-terbium yokumelana nokushisa. Ingxube iyancibilikiswa esithandweni sokungenisa i-vacuum, bese iphonswa ibe ama-flakes amancane. Lawo ma-flakes aguqulwa abe yimpuphu eqinile.

Nakhu lapho amakhona anqunywa khona: abakhiqizi abashibhile basebenzisa ukuhlolwa kokuhlanzeka okungaguquki noma ukweqa ukuhlolwa kobumsulwa. Umphumela? Ama-ring magnets alinganisa kahle kodwa enza u-15-20% ngaphansi kwesilinganiso. Sithumela yonke inqwaba yezinto zokusetshenziswa elabhorethri yangaphandle. Uma okuqukethwe yikhabhoni noma i-oxygen kuphansi ngo-0.05%, siyakwenqaba. Lokho kuzwakala kuyinto exakile kuze kube yilapho usushintshe ama-rings ayi-10,000 ngoba alahlekelwe ukuguquguquka ku-hot motor.

Inqubo Yokuhlikihla (I-Powder Metallurgy)

Impuphu ecolekile icindezelwa kudayi ngaphansi kwensimu enamandla kazibuthe. Kuma-ring magnets, leyo nsimu iqondanisa izinhlayiya - lokhu kuqondanisa kunquma ngqo ukuphuma kwakho kokugcina kazibuthe. Bese ama-compact “aluhlaza” acindezelwe aya esithandweni esishisayo.

Ukushisisa kushisa izinto kuze kufike ezingeni lokuncibilika (cishe ku-1060–1100°C) kugesi evalekile noma engasebenzi. Izinhlayiya ziyahlangana, zinciphise ingxenye cishe ngo-15–20% ngendlela elawulwayo. Lokhu kuncipha kuyabikezelwa - kodwa kuphela uma izinga lokushisa lesithando sakho nesikhathi kufakwe ngaphakathi. Ukukhukhuleka okungu-10°C ihora lonke kungakhiqiza izindandatho ezinezimbobo kakhulu noma eziqhekeka kakhulu.

Ngemva kokusha, omayibuthe bayapholiswa bese bevuthwa (bashiswa) ngezinyathelo eziningi. Lokhu kuthuthukisa ukuphoqelelwa kokugcina - ukumelana kukamayibuthe ne-demagnetization. Yeqa umjikelezo wokushisa bese umayibuthe wakho wendandatho uzozikhipha wona endaweni efudumele.

Ukwakha Nokubumba

Ama-magnet endandatho acwebezelayo aphuma esithandweni esiqinile futhi abuthakathaka kodwa angakabi sezingeni lokugcina. Umshini wokugaya wenziwa ngamathuluzi ambozwe ngedayimane noma umshini wokugaya kagesi (i-EDM) ngoba i-carbide ejwayelekile ngeke iyinqume.

Ububanzi bangaphakathi (ID) kanye nobubanzi bangaphandle (OD) kugaywe ukuze kubekezelelwe. Ngendandatho evamile yezimboni, sibamba u-±0.05mm ku-ID kanye ne-OD. Ngezinhlelo zokusebenza ezinembile njengezindandatho zokufaka ikhodi, zehla ziye ku-±0.01mm. Ngikhumbula iqembu lapho ikhasimende lichaze "ukubekezelelwa okujwayelekile" - bese likhononda ngokuthi ukugijima okungu-0.1mm kubangele ukuthi ibhereji labo lishise ngokweqile. Manje sihlala sibuza: iyini ingxenye yokuhlangana, futhi iyini indawo yokuhlukanisa?

 

Inqubo Yokwenza Umazibuthe Nokumboza

Ukuqina Kwe-Axial vs Radial

Yilapho i-ring magnet iba wusizo noma ingasebenzi. I-magnetization akuyona isethingi ezenzakalelayo - kufanele icaciswe.

- Ukwenziwa kwe-Axial magnetization kusho ukuthi izinsika ezisenyakatho neziseningizimu zisebusweni obubili obuyisicaba. Lokhu kuvamile kuma-coupling kazibuthe, ama-holding rings, kanye nama-speaker assemblies.
- Ukwenziwa kwe-radial magnetization kusho ukuthi izigxobo zisebubanzi obungaphakathi nobangaphandle - ubuso obunye busenyakatho, ubuso obuphambene buseningizimu, kodwa insimu yamagnetic iphuma nge-radially. Yilokhu okudingayo kuma-rotor e-DC motor angenamabhulashi, ama-magnetic bearings, kanye nama-sensor athile.

Ngibone onjiniyela be-oda izindandatho ezingu-5000 ezisebenzisa ugesi, kodwa baqaphela ukuthi bakhohlwe ukutshela ifektri inani lezinsika (izinsika ezimbili, izinsika ezine, izinsika ezingu-8). Ifektri yazenza zonke izinsika ezimbili. Izinsika zasebenza, hhayi nje ukuze zisetshenziswe. Njalo qinisekisa isiqondiso sogesi sama-magnets endandatho ngomdwebo okhombisa ukuqondiswa kwezinsika maqondana nokhiye noma uphawu.

Izindlela Zokumboza Nemiphumela Yazo

Ama-magnet endandatho ye-Neodymiumcishe ziyi-60% yensimbi – zizogqwala emahoreni amaningi emoyeni omanzi. Ukumboza akulona ikhambi.

- I-NiCuNi (i-nickel-copper-nickel): Ijwayelekile yokusetshenziswa kwezimboni okomile. Iqinile, iyaqhuba, futhi incane (10–20µm). Kodwa kuqala ukuklwebheka kanye nokugqwala.
- I-Epoxy: Ijiyile (25–50µm), ayihambisi umoya, futhi imelana kakhulu nokufuthwa ngosawoti kanye nomswakama. Imbi kodwa iqinile. Siyisebenzisela izinzwa zangaphandle kanye nezinhlelo zokusebenza zasolwandle.
- I-Zinc: Ishibhile futhi iyadela. Ilungele ukuhlanganiswa kwangaphakathi okungakaze kubone ukujiya.
- Ukudlulisa / ukuphosphata: Kuncane kakhulu – kuphela kuma-magnet azonamatheliswa noma ahlanganiswe ngaphezulu, ngoba izinamathiseli zinamathela kangcono endaweni elukhuni, enezimbobo.

Iklayenti lake layeka ukusebenzisa i-epoxy lasebenzisa i-nickel kuma-rings ukuze lenze inzwa yepompo yamanzi. Ezinyangeni ezintathu kamuva, yonke i-ring yayiqala ukugqwala. Isimangalo sewaranti sabiza ngaphezu kwebhetshi yonke. Ungaqageli - hlola isampula endaweni yakho yangempela.

 

Ukulawulwa Kwekhwalithi Ekukhiqizweni Kwamaginethi

Ukubekezelelana Nokuhlolwa Okulinganiselwe

I-magnet ngayinye yendandatho iyahlolwa - kodwa akuwona wonke ama-fektri ahlola ngendlela efanayo. Sisebenzisa ukulinganisa okuzenzakalelayo kwe-OD, i-ID, kanye nobukhulu kuma-oda enziwe ngokwezifiso angu-100%. I-micrometer ye-laser iskena ingxenye ngayinye ngaphansi komzuzwana. Noma iyiphi indandatho engaphandle kokubekezelelana okuvunyelwene ngayo ingena ebhodleleni lezingcezu.

Kodwa nansi inkinga: ukubekezelelana kusebenza kuzo zontathuubukhulu ngokuzimela. Indandatho ingaba ne-OD ephelele, i-ID encane kakhulu ngo-0.03mm, kanye nobukhulu obuphansi ngo-0.1mm. Isazohluleka ukuhlanganiswa. Yingakho udinga ukucacisa ukuthi yiziphi izilinganiso ezibalulekile nokuthi yiziphi ezibhekisela kuzo.

Ukuhlolwa Kokusebenza Nokuqina

Ukujikeleza kwamagnetic kulinganiswa nge-Helmholtz coil noma i-Gauss meter ezindaweni eziningi ezizungeze indandatho. Kumasongo ane-axial magnetized, sihlola insimu ephakathi kanye nensimu eduze kwemiphetho. Kumasongo ane-radially magnetized, sizungezisa ingxenye bese sibheka ukuhambisana kwe-pole-to-pole - ukushintshashintsha okungaphezu kuka-3% kusho ukuthi ukuhambisana ngesikhathi sokucindezela bekungalingani.

Ukuhlolwa kwezinga lokushisa kungenye indlela. Sithatha amasongo amahlanu kuqoqo ngalinye, siwafake kuhhavini ekushiseni okuphezulu okubekiwe (ake sithi 120°C) amahora amabili, siwapholise, bese siphinda silinganise ukugeleza. Uma elahlekelwa ngaphezu kuka-5% womkhiqizo wawo wokuqala, iqoqo liyanqatshwa. Lokho ukuhlolwa okujwayelekile abahlinzeki abaningi “abashibhile” abakweqayo ngoba kuthatha isikhathi futhi kulahla izinto.

 

Lokho Abathengi Okufanele Bakuqinisekise Ngaphambi Koku-oda Ama-Neodymium Ring Magnets

Ubukhulu kanye nokubekezelelana

Bhala ngokucacile. Ungabhali ukuthi “OD 20mm”. Bhala ukuthi “OD 20.00 ±0.05 mm, ID 10.00 +0.02/-0.00 mm, ukujiya 5.00 ±0.03 mm”. Tshela umenzi ukuthi yiziphi izindawo ezihambisanayo. Futhi njalo, cela umbiko wokuhlolwa kwesihloko sokuqala ngaphambi kokukhiqiza okugcwele.

Amabanga Ezinto Ezibalulekile

Amabanga kusukela ku-N35 kuya ku-N55 akutshela umkhiqizo wamandla aphezulu. Inombolo ephezulu ye-N = inamandla kodwa iyaphuka kalula futhi ayibekezeleli ukushisa kakhulu. I-N52 ring magnet ekushiseni kwegumbi iyamangalisa. I-N52 ring magnet ekushiseni okungu-70°C ilahlekelwa amandla angu-12%. I-N42SH ekushiseni okufanayo ayilahlekelwa lutho. Qondanisa ibanga nokushisa kwakho kokusebenza, hhayi inombolo yekhatalogi kuphela.

Isiqondiso Sokwenza Umazibuthe

Lokhu akuyona "into enhle ukuba nayo". Yipharamitha eyodwa echazwe kabi kakhulu. Beka umcibisholo emdwebeni wakho. Bhala ukuthi "i-axial magnetized, enyakatho ebusweni obuphezulu". Noma "i-radial 4 pole, ububanzi bangaphandle enyakatho". Uma ungakwazi ukukubona ngeso lengqondo, cela isampula ene-magnetized - iphepha kanye ne-iron filings kuzokukhombisa iphethini ngokushesha.

 

Ukukhiqizwa Ngokwezifiso Kwama-Neodymium Ring Magnets

Inqubo Yokwakha Ukuze Uphrinte

Uma udinga i-ring magnet engekho kukhathalogi – isilinganiso se-ID/OD esingajwayelekile, uqweqwe oluthile, iphethini yezinti eziningi – ubhekeomaginethi be-neodymium ngokwezifisoInqubo ilula: uthumela umdwebo noma isampula, sibuyekeza ukubekezelelana kanye nokwenzeka kokusebenzisa amathuluzi, bese sicaphuna izindleko zokusebenzisa amathuluzi (uma zikhona) kanye nentengo ngengxenye ngayinye.

Amathuluzi okusebenzisa omaginethi endandatho ngokuvamile ahlanganisa ama-dies kanye nezinto zokugaya. Lindela kusengaphambili u-$500–$2000 ngosayizi abangajwayelekile. Leyo ndleko incishiswa ngaphezu kwenani le-oda lakho. Uma unamavolumu aphezulu (izingcezu ezingaphezu kuka-10,000), amathuluzi awabalulekile ngengxenye ngayinye.

I-MOQ kanye Nesikhathi Sokuhola

Inani elincane kakhulu lama-oda omantshi endandatho enziwe ngokwezifiso ngokuvamile liqala ezingcezu ezingu-2000–5000 zokukhiqiza okusekelwe ekushiseni. Abanye abahlinzeki bazokwehla (izingcezu ezingu-500–1000) besebenzisa ama-neodymium ahlanganisiwe noma ama-blank esitokweni aguquliwe, kodwa ukusebenza akufani - ama-magnet ahlanganisiwe abuthakathaka cishe ngo-30%.

Izikhathi zokuhola: amasonto angu-4-6 okusebenzisa amathuluzi kanye namasampula okuqala, bese kuba amanye amasonto angu-4-6 okukhiqiza kanye nokumboza ngemuva kokuvunyelwa kwesampula. Ama-oda asheshayo (amasonto angu-2-3 esewonke) angenzeka kodwa lindela ukukhokha iphrimiyamu engu-30-50% futhi wamukele ukubekezelelana okuqinile ohlelweni lwefektri, hhayi olwakho.

 

Ama-Neodymium Ring Magnets asetshenziswa kukho konke kusukela kuma-EV motors kuya kuma-encoder ezokwelapha kuya kuma-fixtures okugcina. Inqubo yokukhiqiza ivuthiwe kodwa ayithetheleli. Thola imininingwane efanele, hlola i-prototype, bese usebenzisana nomhlinzeki obuza imibuzo - hhayi umuntu othi nje "yebo" kuyo yonke inombolo oyibhalayo.

Uma ufuna ukubona amanye amehlo kumdwebo wakho we-ring magnet ngaphambi kokuthi ufake i-oda elikhulu, xhumana nathi. Sithole amaphutha okubekezelelana abengabiza amakhasimende ethu amanani ayisithupha. Yilolo hlobo lwephutha olwenza kanye kuphela.
