Iiseti ezine zeebheringi zatshintshwa ngokulandelelana kwisiphelo sokwandiswa kweshaft yemoto, nto leyo ekugqibeleni yafunyaniswa ukuba ibangelwa yi-shaft voltage. I-shaft voltage yingxaki exhaphakileyo ekusebenzeni nasekuvavanyweni kwee-high-voltage kunye ne-low-voltage high-power motors.
Ukuqinisekisa ukusebenza okuqhelekileyo kwee-motor bearing ezinkulu, iiyunithi zokuvelisa nokulungisa zihlala zijonga i-voltage ye-shaft yemoto; xa ukusebenza kwee-motor bearing kudla ngokufunyaniswa ukuba akusebenzanga kakuhle, fumanisa ingxaki ye-shaft voltage, kodwa kwakhona jonga umlinganiselo. I-Shaft voltage yi-voltage eveliswa phakathi kweziphelo ezimbini ze-shaft yemoto okanye phakathi kwe-shaft kunye ne-bearing.
Amaxabiso e-Empirical olawulo lwe-voltage ye-axial tile motor shaft
Kwiimoto zethayile ze-axial, impembelelo yevolthi yeshaft ekusebenzeni kwemoto inkulu kakhulu. Ifilimu yeoyile yelubricant inefuthe elithile lokuthintela, ivolthi encinci yeshaft ivelisa umsinga omncinci weshaft awunampembelelo ingako kwithayile ye-axial, xa ixabiso elisebenzayo levolthi yeshaft lingaphantsi kwe-0.5V, ayizukubangela ukungaphumeleli kwibheri etyibilikayo. Xa ivolthi yeshaft inkulu ukuya kwinqanaba elithile, ivolthi yeshaft iya kuphuka kwefilimu yeoyile, yenze isekethe yomsinga weshaft, kukho umonakalo othile kwithayile ye-axial, xa ivolthi yeshaft ingaphezulu kwe-1.5V, i-axial tile iya kutshiswa, kumphezulu we-alloy yethayile kutshiswe imingxunya emininzi kunye namanxeba.
Amaxabiso asemgangathweni olawulo lwangoku lwe-rolling bearing shaft current
Umsinga we-Axial ubuthathaka ngakumbi kwiibheringi eziqengqelekayo, umsinga we-axial omkhulu kune-1A unciphisa kakhulu ubomi bebheringi; umsinga we-axial omkhulu kune-2A, ibheringi iyatshiswa xa isetyenziswa iiyure ezimbalwa. Ke ngoko, iyunithi yokulungisa imisela ukuba umsinga we-shaft weebheringi eziqengqelekayo akufuneki ube ngaphezu kwe-1A, ngaphantsi kwe-1A kuthiwa ngumsinga we-shaft ongenabungozi.
Umonakalo wokwandiswa kweshaft yi-voltage yeshaft kunye nezisombululo
Ukongeza kumonakalo kwiibheringi, kuvavanyo okanye ekusebenzeni kohlobo lwemoto, kuya kubangela amanqanaba ahlukeneyo okukrala kwisandiso se-shaft yemoto; abanye abavavanyi basebenzisa kwisandiso se-shaft kwisisombululo seoyile, kodwa i-voltage ye-shaft inkulu kakhulu, imeko ayisebenzi, kukwakho nabavelisi abasebenzisa isiqabu soxinzelelo lwe-carbon brush ethambileyo, kuquka abanye abavelisi abathwalayo ngokusebenzisa isiqabu soxinzelelo esixhasayo, kodwa akukabikho ukukhuthazwa okuhle okwangoku.
Ulawulo olukhulu lwe-motor shaft kunye nolawulo lwangoku lwe-shaft yingxaki ejongene neshishini ngalinye lemveliso, ukukhuthazwa nokusetyenziswa kwee-insulated bearings kuyisombulula ngempumelelo ingxaki, kodwa ixabiso lee-bearings liphezulu; iinkcukacha ezifanayo zemveliso azikho zonke iimoto ezine-shaft voltage, kwaye inkqubo yemveliso ikwanobudlelwane obukhulu phakathi kwendlela yokuyila, ulawulo lwenkqubo kunye nenkqubo yokuvelisa inokuqikelelwa kwi-motor shaft voltage, kwaye yindlela yophando lweshishini lemveliso yeemoto.
