Oyena nobangela wengxolo yoomatshini: Ingxolo yoomatshini eyenziwa ngabathathu-isigaba semotor esynchronousubukhulu becala yingxolo yempazamo.Ngaphantsi kwesenzo sokunyanzeliswa komthwalo, inxalenye nganye yokuthwala ikhubazekile, kwaye uxinzelelo olubangelwa yi-deformation yokujikeleza okanye i-friction vibration yeendawo zokuhambisa ngumthombo wengxolo yayo.Ukuba i-radial okanye i-axial clearance ye-bearing incinci kakhulu, i-rolling friction iya kwanda, kwaye i-metal extrusion force iya kuveliswa ngexesha lokunyakaza.Ukuba i-gap inkulu kakhulu, ayiyi kubangela ukuba i-bearing igxininiswe ngokungafaniyo, kodwa iphinde iguqule i-gap yomoya phakathi kwe-stator kunye ne-rotor, ngaloo ndlela ikhulise ingxolo, ukunyuka kweqondo lokushisa kunye nokunyakaza.I-bearing clearance yi-8-15um, ekunzima ukuyilinganisa kwisiza kwaye inokugwetywa ngemvakalelo yesandla.
Xa ukhetha iibheringi, kufuneka ucinge: (1) Ukunciphisa isithuba esibangelwa yintsebenziswano yebheringi kunye ne-shaft kunye nesigqubuthelo sokugqibela.(2) Xa usebenza, umahluko wobushushu phakathi kwezangqa zangaphakathi nezingaphandle ubangela ukuba umsantsa utshintshe.(3) Umsantsa phakathi kwe-shaft kunye nesigqubuthelo sokugqibela sitshintsha ngenxa yokwandiswa kwee-coefficients ezahlukeneyo.Ubomi obulinganisiweyo bokuthwala ngu-60000h, ngenxa yokusetyenziswa ngokungafanelekanga kunye nokugcinwa, ubomi benkonzo obusebenzayo buyi-20-40% kuphela yexabiso elilinganisiweyo.
Intsebenziswano phakathi kokuthwala kunye ne-shaft ithatha umngxuma osisiseko, ukunyamezela kwe-diameter yangaphakathi ye-bearing akulungile, kwaye intsebenziswano iqinile.Iibheringi kunye neejenali zingonakaliswa ngokulula ngexesha lokuhlanganisana ngaphandle kobuchule obufanelekileyo kunye nezixhobo.Iibheringi kufuneka zisuswe ngedonsa ekhethekileyo.
Isigwebo sokuthwala ingxolo:
1. Kukho igrisi eninzi kakhulu ekuthwaleni, kuya kubakho isandi sehamile yolwelo kwisantya esiphakathi nesisezantsi, kunye nesandi esingalinganiyo sogwebu ngesantya esiphezulu;oku kubangelwa ukukhuhlana okuqinisiweyo kweemolekyuli zangaphakathi nangaphandle phantsi kokuphazamiseka kwebhola, okukhokelela ekuxutyweni kwegrisi.Igrisi ehlanjululweyo evuza kakhulu kwi-stator windings, ithintela ukuba iphole kwaye ichaphazele ukugquma kwayo.Ngokuqhelekileyo, gcwalisa i-2/3 yendawo yokuzala ngegrisi.Kuya kubakho isandi xa i-bearing iphuma kwioli, kwaye kuya kubakho isandi esikhalayo kunye neempawu zokutshaya ngesantya esiphezulu.
2. Xa ukungcola kwigrisi kuziswa kwi-bearing, izandi zegrabile eziphazamisayo kunye nezingaqhelekanga zinokuthi ziveliswe, ezibangelwa ukunganyanzeki kwendawo yokungcola okuqhutywa ziibhola.Ngokwezibalo, ungcoliseko lwegrisi lubalelwa kwi-30% yezizathu zokuthwala umonakalo.
3. Kukho isandi sexesha "cofa" ngaphakathi kwi-bearing, kwaye kunzima kakhulu ukuyijika ngesandla.Kufuneka kukrokreleka ukuba kukho ukhukuliseko okanye ukukrazuka kwindlela yomdyarho.Izandi "zokuminxeka" ezingapheliyo kwiibheringi, ukujikeleza ngesandla kusenokuba neendawo ezifileyo ezingalungiswanga, ezibonisa iibhola ezaphukileyo okanye iibhola ezonakeleyo.
4. Xa i-looseness ye-shaft kunye ne-bearing ayikho into enzulu, kuya kubakho i-friction yensimbi engapheliyo.Xa umsesane wangaphandle othweleyo urhubuluza kumngxunya wokugquma wesiphelo, uya kuvelisa ingxolo eyomeleleyo nengalinganiyo yefrikhwensi ephantsi kunye nokungcangcazela (okunokuthi kunyamalale emva kokulayishwa kweradial).
