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 yee-coefficients ezahlukeneyo zokwandisa. 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 kweeamolekyuli 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, okubangelwa ukunganyanzeli 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).
