Isizathu esiyinhloko somsindo wemishini: Umsindo wemishini okhiqizwa ama-three-isigaba se-asynchronous motorngokuyinhloko umsindo wephutha elithwalayo. Ngaphansi kwesenzo samandla omthwalo, ingxenye ngayinye yokuthwala ikhubazekile, futhi ukucindezeleka okubangelwa ukuwohloka kokujikeleza noma ukudlidliza okungqubuzanayo kwezingxenye zokudlulisela kuwumthombo womsindo wayo. Uma i-radial noma i-axial clearance ye-bearing incane kakhulu, ukungqubuzana kwe-rolling kuzokwanda, futhi amandla e-metal extrusion azokhiqizwa ngesikhathi sokunyakaza. Uma igebe likhulu kakhulu, ngeke nje libangele ukuthi ukuthwala kugcizelelwe ngokungalingani, kodwa futhi kuguqule igebe lomoya phakathi kwe-stator ne-rotor, ngaleyo ndlela kwandisa umsindo, ukuphakama kwezinga lokushisa nokudlidliza. I-bearing clearance ingu-8-15um, okunzima ukuyikala esizeni futhi ingahlulelwa ngokuzwa kwesandla.
Lapho ukhetha ama-bearing, kufanele ucabangele: (1) Ukuncishiswa kwegebe okubangelwa ukusebenzisana kwe-bearing ne-shaft nesembozo sokugcina. (2) Lapho kusetshenzwa, umehluko wokushisa phakathi kwezindandatho zangaphakathi nezingaphandle ubangela ukuba igebe lishintshe. (3) Igebe phakathi kwe-shaft nekhava yokugcina liyashintsha ngenxa yama-coefficients ahlukene okunweba. Impilo elinganiselwe ye-bearing ingu-60000h, ngenxa yokusetshenziswa okungalungile nokugcinwa, impilo yangempela yesevisi ephumelelayo ingu-20-40% kuphela yenani elilinganiselwe.
Ukubambisana phakathi kwe-bearing kanye ne-shaft kwamukela imbobo eyisisekelo, ukubekezelelana kobubanzi bangaphakathi be-bearing kubi, futhi ukubambisana kuqinile. Ama-Bearings namajenali angonakaliswa kalula ngesikhathi sokuhlanganisa ngaphandle kwesu elifanele namathuluzi. Ama-bearings kufanele asuswe nge-puller ekhethekile.
Isinqumo somsindo wokuzala:
1. Kukhona amafutha amaningi kakhulu ku-bearing, kuzoba nomsindo wesando owuketshezi ngesivinini esiphakathi nesiphansi, nomsindo wegwebu ongalingani ngesivinini esikhulu; lokhu kubangelwa ukungqubuzana okuqinile kwama-molecule angaphakathi nangaphandle ngaphansi kokuyaluza kwebhola, okuholela ekuhlanjululweni kwamafutha. Amafutha ahlanjululwe kakhulu avuza kuma-windings e-stator, avimbele ukuthi angapholi futhi aphazamise ukufakwa kwawo. Ngokuvamile, gcwalisa u-2/3 wesikhala sokuthwala ngamafutha. Kuyoba khona umsindo lapho i-bearing iphuma emafutheni, futhi kuyoba khona umsindo ohlabayo onezimpawu zokubhema ngesivinini esikhulu.
2. Lapho ukungcola kugrisi kulethwa ekuthwaleni, kungase kukhiqizwe imisindo ye-gravel ephakathi nendawo futhi engavamile, okubangelwa ukungapheli kokuma kokungcola okuqhutshwa amabhola. Ngokwezibalo, ukungcoliswa kwamafutha kubala cishe u-30% wezimbangela zokuthwala umonakalo.
3. Kukhona umsindo "wokuchofoza" ngezikhathi ezithile ngaphakathi kwe-bearing, futhi kunzima kakhulu ukuwuphendula ngesandla. Kufanele kusolwe ukuthi kukhona ukuguguleka okuthile noma ukudabuka emjahweni. Imisindo "eminyanisayo" ngezikhathi ezithile kumabheringi, ukuzungezisa okwenziwa ngesandla kungase kube nezindawo ezifile ezingalungisiwe, okubonisa amabhola aphukile noma izibambi zebhola ezilimele.
4. Lapho ukuxega kwe-shaft kanye nokuthwala kungeyona into engathi sína, kuzoba nokungqubuzana kwensimbi okungapheli. Uma iringi yangaphandle ethwele ikhasa emgodini wekhava yokugcina, izokhipha umsindo oqinile futhi ongalingani we-low-frequency kanye nokudlidliza (okungase kunyamalale ngemva kokulayisha kwe-radial).
