Kutheni i-motor shaft ijika ibe luhlaza okwesibhakabhaka?

Kubafundi abaninzi, igama elithi “bluing” aliqhelekanga. I-bluing yinkqubo apho iindawo zentsimbi okanye zentsimbi zifudunyezwa kubushushu obufanelekileyo emoyeni, kumphunga wamanzi okanye kwiikhemikhali ukuze zenze ifilimu ye-oxide eluhlaza okwesibhakabhaka okanye emnyama phezu komphezulu. Nangona kunjalo, kwizinto zemoto, ayisoloko ibangelwa yinkqubo yonyango lwe-bluing ezinikeleyo, kodwa yinto eyenzekayo ngexesha lokuveliswa nokucutshungulwa kwemoto okanye ngexesha lokusebenza kwayo.

Kutheni i-motor shaft ijika ibe luhlaza okwesibhakabhaka?

Ngexesha lokucubungula i-motor shaft ngokwayo, akuyi kubakho zinto zibangela i-bluing factors. Nangona kunjalo, ngexesha lenkqubo yokuhlanganisa i-motor shaft kunye nezinye izinto okanye ukucubungula okulandelayo, i-bluing inokwenzeka. I-motor shaft yohlobo lwekheji kunye ne-rotor core zinobudlelwane obuqhelekileyo bokuphazamiseka. Xa i-rotor core idityaniswe ne-shaft ikwimeko eshushu emva kokufaka i-casting, ubushushu be-cast aluminium rotor buyanele ukubangela i-local bluing (kwindawo yokudibana kwe-rotor core kunye ne-shaft, kwaye idlulele kuzo zombini iziphelo ukuya kumanqanaba ahlukeneyo) kwi-motor shaft. Kwezinye iimeko, inokubonakala imnyama.

Kutheni iirotor zeemoto ezithile ezinengxaki zijika zibe luhlaza okwesibhakabhaka?

Phantsi kweemeko eziqhelekileyo, nokuba ngexesha lesigaba sokuvelisa nokucubungula okanye ukusebenza kwemoto, umphezulu werotor wemoto ngumbala wokuqala emva kokujika kwesinyithi. Nangona kunjalo, kwezinye iimoto ezineempazamo, umphezulu werotor unokubonisa i-bluing yendawo okanye i-bluing iyonke. Ukuhlalutya ukusuka kwinto ebonakalayo ye-bluing yesinyithi, oku kungenxa yengxaki ebangelwa kubushushu obuphezulu kakhulu ngexesha lokusebenza kwemoto. Ngokubanzi, i-bluing yendawo yerotor yemoto ibangelwa ziziphene ezinje ngemigca ephukileyo okanye emincinci kwirotor ngokwayo. Ngexesha lokuvavanywa kweemoto ezinjalo, kuya kubonwa ukungalingani okukhulu kumsinga we-stator, kwaye kwiimeko ezinzima, irotor inokufumana ukuvuza kwe-aluminium. Ukuba yonke irotor ikwimeko ye-bluing, esinye isizathu esinokwenzeka kukuba ubushushu be-stator winding buphezulu kakhulu. Ngeli xesha, i-stator winding isenokubonisa imeko yokuguga kwe-insulation efana nokugqithisa. Ewe, ukuba imicu ye-aluminium yerotor incinci kakhulu, iingxaki ezifanayo zinokwenzeka, kodwa oku kunokwenzeka kuncinci kakhulu.
