5 Kukanganisa Kudzivirira Paunenge Uchigadzira U Shaped Neodymium Magnets

U-shaped neodymium magineti isimba remagetsi. Dhizaini yavo yakasarudzika inotarisisa yakanyanyisa simba remagineti munzvimbo ine compact, ichiita kuti ive yakakodzera kune inoda maapplication akadai semagineti chucks, nyanzvi sensors, yakakwirira-torque mota, uye dzakaomarara zvigadziriso. Nekudaro, kuita kwavo kwakasimba uye chimiro chakaoma zvakare chinoita kuti zviome kugadzirisa. Chikanganiso chimwe chete chinogona kutungamira mukupambadza mari, kunonoka kweprojekiti, kana kutadza kukundikana.

 

Dzivisa izvi 5 zvikanganiso zvakakosha kuti uve nechokwadi chetsika yako yeU-shaped neodymium magineti inoita zvakakwana uye zvakachengeteka:

 

Kukanganisa #1: Kuregeredza Material Brittleness uye Stress Points

 

Dambudziko:Neodymium magineti (kunyanya mamakisi akasimba senge N52) ane brittle, senge porcelain yakanaka. Makona akapinza eiyo U-chimiro anogadzira echisikigo kushushikana pfungwa. Kutadza kuzvidavirira kune iyi brittleness kana uchitsanangura hukuru, kushivirira, kana kubata zvinodiwa kunogona kukonzera kutsemuka kana njodzi kutsemuka panguva yekugadzira, magineti, kutumira, uye kunyangwe kuiswa.

Solution:

Taura Hombe Radhiyasi:Inoda yakakura kwazvo mukati mekona radius (R) dhizaini yako inogona kubata. Tight 90-degree mabhendi ndeye kwete-kwete.

Sarudza giredhi rakakodzera:Dzimwe nguva giredhi yakaderera zvishoma (semuenzaniso, N42 pachinzvimbo cheN52) inogona kupa zvirinani kutyoka kuomarara pasina kupa simba rakawandisa rinodiwa.

Tauriranai kubata zvinodiwa:Ita shuwa kuti mugadziri wako anonzwisisa kuti magineti achabatwa nekuiswa sei. Vanogona kukurudzira kurongedza kwekudzivirira kana kubata zvigadziriso.

Dzivisa makumbo matete:Makumbo akaonda zvakanyanya maererano nehukuru uye simba remagineti anogona kuwedzera zvakanyanya njodzi yekutyoka.

 

Mistake #2: Kugadzira pasina kufunga nezve magnetization gwara

 

Dambudziko:NdFeB magineti anowana simba rawo kubva kune magineti mune yakananga nzira mushure mekunyura. Kune magineti akafanana neU, matanda anenge anogara ari pamagumo emakumbo. Kana iwe ukatsanangura chimiro chakaoma kana saizi inodzivirira iyo magnetizing gadziriso kubva pakubata zvakanaka zviso zvepango, iyo magineti haisvike pakusimba kwayo kwemagnetization kana inogona kukonzera kukanganisa kwemagnetization.

Solution:

Bvunza nekukurumidza:Kurukura dhizaini yako nemugadziri wemagineti usati wapedza. Uye bvunza nezve magnetizing fixture zvinodiwa uye zvisingakwanisi.

Koshesa kuwanikwa kwepole face:Ita shuwa kuti dhizaini inobvumira kujeka, kusingavharike kupinda kweiyo magnetizing coil kune yese pamusoro peimwe pole yekupedzisira.

Nzwisisa orientation:Taura zvakajeka iyo yaunoda magineti yekumisikidza (axially kuburikidza nedanda) mune yako yakatarwa.

 

Kukanganisa #3: Kurerutsa kukosha kwekushivirira (kana kuamisa zvakanyanya)

 

Dambudziko:Sintered Nd magineti anodzikira panguva yekugadzira, zvichiita kuti post-sintering machining yakaoma uye ine ngozi (ona Mistake #1!). Kutarisira "machine metal" kushivirira (± 0.001 mukati) hazvigoneke uye zvinodhura zvakanyanya. Sezvineiwo, kutsanangura kushivirira kwakafara zvakanyanya (± 0.1 mukati) kunogona kukonzera magineti isingagone kushandiswa mugungano rako.

Solution:

Nzwisisa zviyero zveindasitiri:Nzwisisa akajairika "sintered" kushivirira kweNdFeB magineti (kazhinji ± 0.3% kusvika ± 0.5% yehukuru, nekushivirira kudiki kunowanzo ± 0.1 mm kana ± 0.005 mukati.).

Iva pragmatic:Rondedzera kushivirira kwakasimba chete pazvinonyanya kukosha kushanda, senge nzvimbo dzekubatana. Mune zvimwe zviitiko, kushivirira kwakaderera kunogona kuchengetedza mari uye kuderedza njodzi.

Kurukurai nezvekugaya:Kana nzvimbo ichifanira kunyatsojeka (semuenzaniso, chiso chechuck), tsanangura kuti kukuya kunodiwa. Izvi zvinogona kuwedzera mutengo wakakosha uye njodzi, saka zvishandise chete kana zvichidikanwa. Iva nechokwadi chokuti mugadziri anoziva kuti ndezvipi nzvimbo dzinoda kukuya.

 

Kukanganisa #4: Kuregeredza kuchengetedzwa kwezvakatipoteredza (machira)

Dambudziko:Bare neodymium magineti anoora nekukurumidza kana akaiswa muhunyoro, hunyoro, kana mamwe makemikari. Corrosion inotanga pamakona emukati asina njodzi uye inokurumidza kukanganisa magineti kuita uye kurongeka kwechimiro. Kusarudza jasi risiri iro, kana kufungidzira kuti jira rakajairwa rakakwana kune dzakaomarara nharaunda, zvinogona kutungamirira mukukundikana nguva isati yakwana.

Solution:

Usambofa wakafuratira coatings:Bare NdFeB haina kukodzera magineti anoshanda.

Coatings inofanira kufanana nenharaunda:Standard nickel-copper-nickel (Ni-Cu-Ni) plating yakakodzera kushandiswa kwakawanda kwemukati. Kune nharaunda dzakanyorova, dzakanyorova, dzekunze, kana dzakafumurwa kumakemikari, tsanangura iyo yakagadzika coating senge:

Epoxy/Parylene:Yakanakisa mwando uye makemikari kuramba, uye magetsi ekudzivirira.

Ndarama kana zinc:kuitira kusaita ngura chaiyo.

Gobvu epoxy:kunharaunda dzakaoma.

Taura mukati mekona yekuvhara:Simbisa kuti kupfeka kunofanira kupa yunifomu yekuvhara, kunyanya pa-high-stress mukati memakona eU-shape. Bvunza nezve vimbiso yavo yekushanda.

Funga nezvekuyedza kupfapfaidza munyu:Kana kushorwa kwekuora kwakakosha, tsanangura huwandu hwemaawa ekuyedzwa kwemunyu wekupfapfaidza (semuenzaniso, ASTM B117) iyo magineti yakavharwa inofanira kupfuura.

 

Kukanganisa #5: Kusvetuka iyo Prototype Phase

Dambudziko:Pane njodzi mukusvetukira muhurongwa hombe zvichibva pamuenzaniso weCAD kana dhetabheti chete. Chaiyo-nyika zvinhu zvakaita semagineti kudhonza kugovera, kunyatsokwana kwezvikamu, kubata fragility, kana kupindirana kusingatarisirwe kunogona kungoonekwa nemuenzaniso wenyama.

 

Solution:

Ita odha prototypes: bhajeti uye simbirira pane diki batch yeprototypes kutanga.

Edza zvakasimba: Chinyorwa prototypes kune chaiyo-nyika mamiriro:

Iva nechokwadi chekuenderana uye kushanda mumusangano.

Chaiyo-nyika inodhonza zviyero (inozadzisa zvaunoda here?).

Kubata bvunzo (ichapona kuisirwa?).

Miedzo yemamiriro ekunze (kana zvichibvira).

Dzokorora sezvinodiwa: Shandisa prototype mhinduro kukwirisa zviyero, kushivirira, machira, kana mamakisi usati wazvipira kugadzira zvinodhura.
