Me pēhea te hanga i ngā aukume mowhiti Neodymium?

Mena kua wetewetehia e koe tētahi puranga aukume mowhiti kāore i uru ki tō rotor, kua ngoikore rānei i muri i te marama, kua waikura rānei i mua i te tāutanga, e mōhio ana koe ki te āhua. Ko te raruraru ehara i te rauemi – engari ko te āhua o te hanganga o te aukume.

Kua mātakitaki ahau i ngā kaihoko e whakaaro ana he rite tonu te putanga mai o ngā aukume mowhiti katoa. Kāore. Ko te āputa i waenga i tētahi aukume mowhiti "pai" me tētahi e rere ana mō ngā tau i roto i te motuka, i te pūoko rānei, ka ahu mai i ngā mahi hanga kāore koe e kite.

Nā, anei ngā mea e tupu ana i roto i tētahi toa aukume ritenga – ā, ko te wāhi tēnei e uru puku mai ai te nuinga o ngā hapa utu nui.

Ngā Whakatakotoranga Matua mō ngā Aukume Mowhiti Neodymium

I mua i tā tātou hikoi i roto i te papa wheketere, me whakatika tātou i tētahi mea. Kāore e taea te hanga tika i tētahi mowhiti aukume mēnā he pōhēhē ngā whakatakotoranga.
Ko te tautuhi i ngā rahi tika o te mowhiti aukume te tātari tuatahi i waenga i te wāhanga e taka ana ki roto i tō huihuinga me te wāhanga e piri ana, e wiri ana rānei. Ka hoki anō tātou ki ngā manawanui ā muri ake nei – engari kia mōhio koe ko ia taahiraa e heke iho ana ka whakawhirinaki ki tō tuhi.

 

He Tirohanga Whānui mō te Tukanga Hanganga Mowhiti Neodymium

Te Whakarite Rauemi

Ka tīmata ki te neodymium mata, te rino, me te boron – me ētahi atu huānga tāpiri pēnei i te dysprosium, te terbium rānei hei ātete i te wera. Ka rewahia te koranu i roto i te oumu korehau, kātahi ka makaia hei kongakonga angiangi. Ka hurihia aua kongakonga hei paura matotoru.

Anei te wāhi e tapahia ai ngā kokonga: ka whakamahia e ngā kaihanga utu iti ngā para koretake, ka pekehia rānei ngā tirotiro parakore. Ko te mutunga? He aukume mowhiti e ine pai ana engari e 15–20% te mahi i raro i te whakaritenga. Ka tukuna e mātou ia puranga rauemi mata ki tētahi taiwhanga o waho. Mena he iti iho te ihirangi waro, hāora rānei i te 0.05%, ka whakakorehia e mātou. He ahua pēhi rawa atu tēnā kia whakakapia rā anō e koe ngā mowhiti 10,000 nā te mea kua ngaro te rere o te hau i roto i te motuka wera.

Tukanga Sintering (Paura Metallurgy)

Ka pēhia te paura angiangi i roto i te mata i raro i te papa aukume kaha. Mō ngā aukume mowhiti, ka whakarārangihia e taua papa ngā matūriki – mā tēnei whakarārangitanga ka whakatau tika i tō putanga aukume whakamutunga. Kātahi ka tukuna ngā konganuku "kakariki" kua pēhia ki roto i te oumu whakawera.

Mā te whakawera i te rauemi ki te tata ki te pūmahana rewa (tata ki te 1060–1100°C) i roto i te korehau, i te hau kore mahi rānei. Ka hanumi ngā matūriki, ka whakaiti i te wāhanga mā te 15–20% i runga i te huarahi whakahaere. Ka taea te matapae i tēnei whakahekenga – engari mēnā ka whakaritea te pāmahana me te wā o tō oumu. Mā te nekehanga 10°C mō te haora ka puta he mowhiti he tino pūwero, he pakarukaru rānei.

I muri i te whakamahana, ka whakamataohia ngā aukume, kātahi ka pakeketia (whakamātotoruhia) i roto i ngā taahiraa maha. Mā tēnei ka whakawhanakehia te kaha whakakaha whakamutunga – te ātete o te aukume ki te tango i te aukume. Kaua e uru ki te huringa whakamahana, ā, ka tango i a ia anō tō aukume mowhiti i roto i te whare mahana.

Te Mīhini me te Hanga

Ka puta mai ngā aukume mowhiti whakakoi i te oumu he mārō, he pakarukaru, engari kāore anō kia tae ki ngā rahinga whakamutunga. Ka mahia te mīhini mā te whakamahi i ngā taputapu pania taimana, te mīhini tuku hiko rānei (EDM) nā te mea kāore e taea te tapahi e te carbide paerewa.

Ko te diameter o roto (ID) me te diameter o waho (OD) ka hurihia kia rite ki te manawanui. Mō te mowhiti ahumahi noa, ka pupuri mātou i te ±0.05mm i runga i te ID me te OD. Mō ngā tono tika pērā i ngā mowhiti encoder, ka heke ki te ±0.01mm. E maumahara ana ahau ki tētahi puranga i tohua ai e te kiritaki te "manawanui paerewa" - kātahi ka amuamu nā te oma 0.1mm i wera rawa ai tā rātou peera. Ināianei ka pātai tonu mātou: he aha te wāhanga hono, ā, he aha te ātea?

 

Te Tukanga Whakamātautau me te Paninga

Te Aukumetanga Tuaka me te Aukumetanga Porowhita

Koinei te wā e whai hua ai, e kore rānei e whai hua ai te mowhiti aukume. Ehara te aukume i te tautuhinga taunoa – me tohu noa iho.

- Ko te tikanga o te aukumetanga tuaka ko ngā pou raki me ngā pou tonga kei runga i ngā mata papatahi e rua. He mea noa tēnei mō ngā hononga aukume, ngā mowhiti pupuri, me ngā huihuinga kaikorero.
- Ko te tikanga o te aukumetanga pūtoro kei ngā diameter o roto, o waho hoki ngā pou – kei te raki tetahi mata, kei te tonga te mata o tera taha, engari ka pupuhi te papa aukume ki te pūtoro. Koinei te mea e hiahiatia ana e koe mō ngā rotor motuka DC kore paraihe, ngā peera aukume, me ētahi pūoko.

Kua kite ahau i ngā miihini e tono ana i te 5000 mowhiti aukume porowhita, ā, ka mōhio kua wareware rātou ki te kōrero ki te wheketere mō te maha o ngā pou (2-pou, 4-pou, 8-pou). I hangaia katoatia e te wheketere he 2-pou. I pai ngā mowhiti, engari kāore i pai mō te tono. Me whakaū tonu te ahunga aukume o ngā aukume mowhiti mā te tuhi e whakaatu ana i te aronga o te pou e pā ana ki te ara matua, ki te tohu rānei.

Ngā Tikanga Paninga me Ōna Pānga

Ngā aukume mowhiti Neodymiumhe 60% te rino – ka waikura i roto i ngā hāora i te hau makuku. Ehara te paninga i te mea whakapaipai.

- NiCuNi (nikara-parahi-nikara): Paerewa mō te whakamahinga ahumahi maroke. He mārō, he kawe hiko, he angiangi (10–20µm). Engari kotahi te karawarawa ka tīmata te waikura.
- Epoxy: Matotoru ake (25–50µm), kāore e kawe hiko, ā, he ātete ake ki te rehu tote me te makuku. He kino engari he pakari. Ka whakamahia e mātou mō ngā pūoko o waho me ngā mahi moana.
- Konutea: He iti te utu, he patunga tapu hoki. He pai mō ngā huihuinga o roto e kore e kitea te hauhautanga.
- Te whakapūmautanga/te whakapūpūtanga: Tino angiangi – mō ngā aukume anake ka whakapirihia, ka whakakikoruatia rānei, nā te mea ka piri pai ake ngā piripiri ki te mata taratara, ki te mata pūwero.

I mahue i tētahi kiritaki te whakamahi i te epoxy, ā, i whakamahia ngā mowhiti nikara hei pūoko papu wai. E toru marama i muri mai, kua memeha haere ngā mowhiti katoa. He nui ake te utu o te kereme whakamana i te utu mō te puranga katoa. Kaua e whakaaro noa - whakamātauria he tauira i roto i tō taiao tūturu.

 

Te Mana Kounga i roto i te Hanga Aukume

Te Manawanui me te Whakamātautau Ahu

Ka tirohia ia mowhiti aukume – engari kāore e rite te tirotiro a ia wheketere. Ka whakamahia e mātou he inenga whatu aunoa mō te OD, te ID, me te matotoru mō te 100% o ngā ota ritenga. Ka matawaihia ia wāhanga e te maikoromita taiaho i raro i te hēkona. Ko ngā mowhiti katoa i waho o te manawanui kua whakaaetia ka maka ki roto i te ipu para.

Engari anei te mahanga: e pā ana te manawanui ki ngā mea e torungā ine motuhake. Tērā pea he OD tino tika tō te mowhiti, he iti rawa te ID he 0.03mm, ā, he 0.1mm te tawhiti o te matotoru. Kāore tonu e rahua te huihuinga. Koia te take me tohu koe ko ēhea ngā inenga he mea nui, ko ēhea hoki he tohutoro.

Te Whakamātautau Mahi me te Pumautanga

Ka inehia te rerenga aukume mā te whakamahi i te koiri Helmholtz, i te mita Gauss rānei i ngā pūwāhi maha huri noa i te mowhiti. Mō ngā mowhiti aukume tuaka, ka tirohia e mātou te āpure waenga me te āpure e tata ana ki ngā taha. Mō ngā mowhiti aukume radial, ka hurihia e mātou te wāhanga ka rapu i te ōritetanga o te pou-ki-pou – ko te rerekētanga neke atu i te 3% ko te tikanga he kore taurite te whakaritenga i te wā e pēhi ana.

Ko te whakamātautau pāmahana tētahi atu paparanga. Ka tangohia e mātou e rima ngā mowhiti mai i ia puranga, ka tukuna ki roto i te oumu i te pāmahana mōrahi kua tohua e koe (hei tauira, 120°C) mō ngā haora e rua, ka whakamatao, ka ine anō i te rere. Mena ka ngaro atu i te 5% o tā rātou putanga taketake, ka whakakahoretia te puranga. He whakamātautau paerewa tēnā e karohia ana e te nuinga o ngā kaiwhakarato "iti te utu" nā te mea ka roa te wā, ā, ka para te rauemi.

 

Ngā Mea Me Whakaū e Ngā Kaihoko I Mua I Te Tono I Ngā Aukume Mowhiti Neodymium

Ngā Ahu me te Manawanui

Kia tika. Kaua e tuhi "OD 20mm". Tuhia "OD 20.00 ±0.05 mm, ID 10.00 +0.02/-0.00 mm, matotoru 5.00 ±0.03 mm". Kōrero atu ki te kaihanga ko ēhea mata e hono ana i ngā mata. Ā, me tono tonu kia tukuna he pūrongo tirotiro tuatahi i mua i te hanga katoa.

Ngā Tohu Rauemi

Mā ngā tohu mai i te N35 ki te N55 ka kitea te hua pūngao mōrahi. Ko te tau N teitei ake = he kaha ake engari he pakarukaru ake, ā, he iti ake te ātete ki te wera. He mea whakamiharo te aukume mowhiti N52 i te pāmahana rūma. Ka ngaro te 12% o tōna kaha i te aukume mowhiti N52 i te 70°C. Kāore he mea e ngaro i te N42SH i te pāmahana kotahi. Tauritehia te tohu ki tō pāmahana whakahaere, kaua ko te tau o te putumōhio anake.

Aronga Aukumetanga

Ehara tēnei i te "mea pai ki te whai". Koinei te tawhā kotahi i tino hē te tautuhi. Whakatakotoria he pere ki tō tuhi. Tuhia "axial magnetized, north on top face". Me "radial 4‑pole, outer diameter north". Ki te kore e taea e koe te whakaaro, tonoa he tauira magnetized - mā te pepa me ngā kongakonga rino ka whakaatu tonu i te tauira ki a koe.

 

Te Hanga Ritenga mō ngā Aukume Mowhiti Neodymium

Tukanga Hanga-ki-Tā

Mena kei te hiahia koe i tētahi aukume mowhiti kāore i roto i tētahi rārangi taonga – he ōwehenga ID/OD kāore i te paerewa, he paninga motuhake, he tauira maha-pou – kei te titiro koe kiaukume neodymium ritengaHe māmā noa te tukanga: ka tukuna mai he tuhi, he tauira rānei, ka arotakehia e mātou ngā tūponotanga me te whaihua o ngā taputapu, kātahi ka whakahuahia te utu taputapu (mēnā he mea kei a koe) me te utu mō ia wāhanga.

Ko ngā taputapu mō ngā aukume mowhiti he huinga mate me ngā taputapu huri. Me tumanako ki te $500–$2000 i mua mō ngā rahi kāore i te paerewa. Ka whakahekehia taua utu ki runga i te rahinga o tō ota. Mō ngā rahinga nui (neke atu i te 10,000 ngā wahi), he iti noa iho ngā taputapu mō ia wahi.

MOQ me te Wā Arataki

Ko te iti rawa o ngā ota mō ngā aukume mowhiti ritenga ka tīmata i te 2000–5000 ngā wahi mō te hanga i runga i te sintering. Ka whakaitihia e ētahi kaiwhakarato (500–1000 ngā wahi) mā te whakamahi i te neodymium kua herea, i ngā mea kua whakarerekētia rānei, engari kāore te mahi i rite - he ngoikore ake ngā aukume kua herea tata ki te 30%.

Ngā wā ārahi: 4–6 wiki mō te hanga taputapu me ngā tauira tuatahi, kātahi ka 4–6 wiki anō mō ​​te hanga me te paninga i muri i te whakaaetanga tauira. Ka taea ngā ota tere (2–3 wiki katoa) engari me tumanako ka utua he utu nui 30–50% me te whakaae ki ngā manawanui pakari ake i runga i te wātaka a te wheketere, ehara i tāu.

 

E whakamahia ana ngā aukume mowhiti neodymium i roto i ngā momo mea katoa mai i ngā motuka hiko ki ngā mīhini whakakōwae hauora tae atu ki ngā taputapu pupuri. He pakari te tukanga hanga engari he uaua. Tikina ngā whakaritenga tika, whakamātauria he tauira, ka mahi tahi me te kaiwhakarato e pātai ana - kaua ko te kaiwhakarato e kī noa "āe" ki ia tau ka tuhia e koe.

Ki te hiahia koe kia tirohia anō tō mowhiti aukume i mua i te tuku ota nui, whakapā mai. Kua kitea e mātou ētahi hapa manawanui e ono mati te utu mō ā mātou kiritaki. Koinei te momo hapa ka mahia kotahi noa iho.
