Menene Bearing na Electromagnetic?

 

Ƙarfin lantarki, wani abu mai sauƙi wanda ke amfani da ƙarfin filin lantarki da ƙarfin filin maganadisu don sa shaft ɗin ya tsaya.

 

Ka'idarbearings na lantarkiyana kama da na jirgin ƙasa mai kama da na maglev. Jirgin ƙasa mai kama da na maglev kayan aikin sufuri ne na zamani na jirgin ƙasa mai fasaha, wanda ke samar da dakatarwa da jagora mara taɓawa tsakanin jirgin da hanyar jirgin ta hanyar ƙarfin lantarki, sannan kuma yana amfani da ƙarfin lantarki da injin layi ya samar don jawo jirgin ya yi aiki, yana rage gogayya.

 

Theelectromagnetic haliyana gano siginar karkata matsayi na shaft ta hanyar firikwensin matsayi, yana aika siginar zuwa ga mai sarrafawa, kuma yana sarrafa kwararar lantarki ta hanyar amplifier wutar lantarki, don samar da canji a cikin ƙarfin lantarki don sa sandar ta tsaya a wurin da aka ƙayyade.

 

2. Fa'idodi da rashin amfanin bearings na lantarki

 

Fa'idodinbearings na lantarki:

 

1) Babban gudu

 

Bearings na lantarki suna ba da damar rotor ya juya a babban gudu, saurinsa galibi yana iyakance ne da ƙarfin kayan, yana iya aiki a ƙarƙashin ɗaruruwan dubban juyin juya hali a minti ɗaya, kuma daidaiton juyawa na rotor ya kai matakin micron ko ma sama da haka, wanda shine saurin da daidaiton da bearings na injiniya na yau da kullun za su iya kaiwa nesa ba kusa ba.

 

2) Ƙarancin amfani da wutar lantarki

 

Tunda bearings na lantarki ba su da hulɗa ta inji, babu kusan gogayya, kuma yawan wutar lantarki don shawo kan gogayya yana da ƙasa sosai. A gudun 10,000 r/min, yawan wutar lantarki kusan kashi 15% ne kawai na bearings na inji.

 

3) Ƙananan farashin kulawa da tsawon rai

 

Saboda bearings na lantarki ba su da alaƙa ko lalacewa, babu hulɗa tsakanin saman motsi, babu gogayya ta injiniya da gajiyar hulɗa, yana magance matsalar asara da rayuwar sassan injina, kuma amincin sassan lantarki ya fi na sassan injina na gargajiya girma.

 

4) Ba a buƙatar shafa man shafawa ba

 

Bearings na lantarki ba sa buƙatar shafawa, kawar da tsarin shafawa da sauran na'urori, wato, adana sarari da kuma rashin gurɓata muhalli ta hanyar tsarin shafawa.

 

5) Yana iya aiki a cikin injin tsabtace iska da kuma kewayon zafin jiki mai faɗi, kuma ana iya bambanta tsarin.

 

Rashin amfani da matsalolin bearings na lantarki:

 

1) Bearings na lantarki suna buƙatar ƙarfin filin lantarki mai yawa, kuma aikace-aikacen yana da iyaka.

 

2) Mai sarrafawa shine mabuɗin, yadda ake tsara mai sarrafawa mai tsari mai sauƙi, kyakkyawan aiki da sauƙin gyara kurakurai abu ne mai wahala na fasaha.

 

3) Yadda ake tantance tasirin kurakuran sarrafawa da kera su akan sarrafa na'urar lantarki shi ma batu ne mai wahala.

 

4) Yadda ake sarrafa rashin daidaiton rotor yana buƙatar ƙarin bincike da gogewa a aikace.

 

3. Amfani da bearings na lantarki

 

A halin yanzu, ana amfani da bearings na lantarki sosai a fannoni da yawa, kamar jiragen ƙasa masu saurin gaske, centrifuges masu saurin gaske, janareto masu amfani da ruwa, ƙafafun motsi na angular momentum flywheels na motocin sararin samaniya, mitar kwarara, mita mai yawa, mitar wutar lantarki, famfunan injinan iska, masu daidaita daidaito da na'urorin gyroscopes.
