Nhanganyaya kumabheyaringi ane insulated electrically

 

Chekutanga, chinangwa chemabheringi anochengetedza magetsi

 

Mabheya anonzi mabheya anodzivirirwa nemagetsi zvakare mabheya anodzivirirwa nemagetsi, uye mabheya anodzivirirwa nemagetsi anosanganisira mabheya ese anotenderera anogona kudzivirira kupfuura kwemagetsi. Mabheya ane ceramic coating, ese ari maviri mhete dzemukati nedzekunze, anonzi mabheya anodzivirirwa nemagetsi. Kupfekedzwa kweceramic kunodzivirira kupfuura kwemagetsi uye kune kugona kwekudzivirira kupisa.

 

Zvinhu zvinotenderera zvemabheyaringi emhando yehybridzvakagadzirwa neceramic saka zvine hunhu hwekudzivirira kupisa. Zvakagadzirwa nezvinhu zvinotenderedza kudzivirira kupfuura kwemagetsi.

 

Chechipiri, kusarudzwa kwekudzivirira kutakura

 

Kazhinji, zvakaoma kubvisa zvachose musiyano uripo mukati mebearing. Zvisinei, kana tikakwanisa kumisa kana kuderedza zvakanyanya kuyerera kwemagetsi kuburikidza nebearing, tinogona kudzivirira galvanic corrosion yebearing. Mhando dzakasiyana-siyana dzemabearing anodzivirirwa parizvino dzakagadzirirwa chinangwa ichi. Zvichienderana nerudzi rwevoltage inogadzirwa, nzira yekudzivirira yebearing inosarudzwa.

 

1. Voltage inokonzerwa inogadzirwa pamwe chete neshaft

 

2. Voltage iri pakati pemubato nechigaro chekutakura

 

Kana voltage ikaitika pakati peshaft neimba, simba remagetsi rinoyerera nepabearing yega yega nenzira imwe chete. Izvi zvinonyanya kukonzerwa nevoltage ye common-mode inounzwa ne frequency converter. Muchiitiko ichi, mabearing ari kumativi ese emota anofanira kunge akadzivirirwa, uye chinhu chikuru pakusarudza insulation hunhu hwenguva yemagetsi nevoltage. Muchiitiko chevoltage yeDC kana low-frequency AC voltage, insulation effect inoenderana ne pure resistance value ye insulation layer; Muchiitiko che high-frequency AC voltages (inowanzo kuwanikwa mumidziyo inoshandisa frequency converters), zvinoenderana ne capacitive reactance ye insulation.

 

3. Mamiriro ezvinhu akajairika ekukuvara kwebheyaringi kunokonzerwa ne overcurrent

 

1. Zviratidzo pamigwagwa yemujaho uye zvinhu zvinotenderera

 

Pasinei nekuti bearing inofambiswa ne direct current kana alternating current (frequency iri pasi pe MHz), tinogona kuwana kutadza kwakafanana mukati mebearing.

 

2. Zviratidzo zve electro-ekukurwa kwevhu

 

Inonzi electro-erosion groove inoreva continuous periodic groove iri pamusoro penzira yemujaho ichienda kwainoshanda. Zvizhinji zvezviitiko izvi zvinokonzerwa nemagetsi anopinda nepabheyaringi.

 

Chechina, pasi pemaikorosikopu kutarisa chimiro chakakuvara chebheyaringi re overcurrent

 

Zviri pachena kuti nzvimbo dzese dzakakuvara dzakafukidzwa nemakomba nemajoini e μm solder kuburikidza ne scanning electron microscopy (SEM).

 

Chechipiri, maitiro ekukuvara kwekutakura

 

Makomba aya nekubatana kwesimbi zvinokonzerwa nekubuda kwemagetsi pakati penzvimbo diki dzekubata pamusoro penzira yemujaho uye zvinhu zvinotenderera. Kana mvura yanyatsonyoroveswa, magetsi anopwanya nepakati penzvimbo isina simba yefirimu remafuta, uye simba rinogadzirwa nemagetsi rinonyungudutsa pamusoro pesimbi iri pedyo nekukasira.

 

Mumamiriro ekukweshana kwakasanganiswa (kubatana kwesimbi nesimbi), nzvimbo dziri pedyo dzinobatanawo, asi dzinokurumidza kuparadzaniswa sezvo bearing ichifamba. Muzviitiko zvese izvi, zvinhu zvinobva pamusoro pesimbi zvobva zvaoma kuita solder joint. Kunewo mamwe ma solder joints anosanganiswa ne lubricant uye mamwe anoiswa pamusoro pe raceway. Sezvo bearing inoramba ichifamba, ma solder joints aya nema pits anomonerwawo uye anogadziriswa. Pasi pesimba remagetsi rinoenderera mberi, maitiro ekunyunguduka nekuoma anodzokororwa kakawanda pamusoro penzvimbo yakatetepa yenzvimbo iri pedyo.

 

6. Simba remagetsi pamafuta anozorwa

 

Mafuro emagetsi anogonawo kukanganisa mafuta anozorwa. Mafuta epasi nezvimwe zvinowedzerwa zvinooreswa uye zvinotsemuka. Kuchinja uku kunogona kuonekwa zvakajeka mu infrared spectrogram. Kukwegura nguva isati yakwana uye kuunganidzwa kwezvidimbu zvesimbi zvinogona kutungamira mukushata kwekushanda kwemafuta uye zvinogonawo kutungamira mukupiswa kwemabheringi.
