Izizathu zokuthwala ukushisa ngokweqile zihlanganisa:

①ukuntuleka kwamafutha;②amafutha amaningi noma amafutha amaningi kakhulu;③amafutha angcolile, ahlanganiswe nezinhlayiya ezingcolile;④ukugoba kwe-shaft⑤ukulungiswa kwedivaysi yokudlulisela okungalungile (okufana ne-eccentricity, ibhande lokudlulisela noma ukuhlanganisa Uma iqine kakhulu, ingcindezi ku-bearing izokhuphuka, futhi ukungqubuzana kuzokwanda);⑥Isembozo sokugcina noma ukuthwala akufakiwe kahle, futhi inqubo yokuhlanganisa ayilungile, okwenza indawo yomjaho yonakaliswe futhi ikhubazeke, okubangela ukungqubuzana nokushisa ngesikhathi sokusebenza;ukulingana kuqine kakhulu noma kuxege kakhulu;⑦I-shaft Ithonya lamanje (ngoba inkambu kazibuthe ye-stator yezinjini ezinkulu ngezinye izikhathi ayilingani, amandla e-electromotive akhangwe akhiqizwa ku-shaft. Izizathu zenkundla kazibuthe engalinganiseli ukugqwala kwengqikithi yendawo, ukumelana okukhulayo, kanye nezikhala zomoya ezingalingani phakathi i-stator ne-rotor, okuholela ku-shaft I-current ibangela ukushisa kwamanje kwe-eddy. I-voltage ye-shaft ye-shaft current ngokuvamile i-2-3V)⑧Izimo zokukhipha ukushisa zimbi ngenxa yokupholisa umoya.

Ukuhlaziywa kwe-SKF motor ethwele ukwehluleka, ukulungiswa kanye nezinyathelo zokuphikisa kufanele kusekelwe kuzizathu①-③.Izinga likawoyela kufanele lihlolwe futhi lilungiswe ngendlela efanele;uma amafutha ewohloka, hlanza igumbi lokuthwala bese ufaka amafutha afanelekayo esikhundleni salo.

Ngesizathu④, i-shaft egobile kufanele ibekwe ku-lathe ukuze kuqinisekiswe.

Ngezizathu⑤-⑥, ububanzi nokuqondanisa kwe-axial kufanele kulungiswe futhi kulungiswe ngokufanele.

Ngesizathu⑦, i-voltage ye-shaft kufanele ilinganiswe kuqala, lapho kulinganiswa i-voltage ye-shaft.Ungasebenzisa i-3-1OV ephezulu ukumelana ne-voltmeter yamanje ukukala i-voltage v1 phakathi kwamaphethelo amabili e-motor shaft, futhi ulinganise i-voltage v2 phakathi kwesisekelo ne-bearing.Ukuze uvimbele ama-eddy currents kuma-motor bearings, ipuleti le-insulating lifakwa ngaphansi kwesihlalo esinesihlalo ekugcineni kwesinye senjini eyinhloko.Ngesikhathi esifanayo, izembozo ze-insulating plate zengezwe kuma-bolts, izikhonkwane, amapayipi kawoyela nama-flanges phansi kwesihlalo esithwalayo ukuze kunqunywe indlela yamanje ye-eddy.Isembozo sebhodi le-insulation singenziwa ngendwangu ye-laminate (ithubhu) noma i-glass fiber laminate (ishubhu).Iphedi ye-insulating kufanele ibe ngu-5~1Omm ububanzi kunobubanzi bohlangothi ngalunye lwesisekelo sokuthwala.

Ngesizathu⑧, izimo zokungenisa umoya zokusebenza kwezimoto zingathuthukiswa, njengokufaka amafeni, njll.

Ama-elementi aginqikayo nendawo yomjaho iyacindezelwa.Ibhere likhiqiza ukumelana nokuslayida ngenxa yokushelela ngesikhathi sokuzungezisa.Ukusebenzisana kwamandla aphansi kanye nokumelana nokuslayida kokuslayida kumarola anayo kanye nekheji ngaphansi kokusebenza kwesivinini esikhulu kubangela ukuthi izakhi eziginqikayo zishibilike kumgwaqo womjaho.Futhi indawo yomjaho iyacindezelwa.

Kunezizathu eziningi zokukhathala kokuxebuka kwezakhi ezigoqayo.Ukugunyazwa okuthwala ngokweqile, ukusetshenziswa okunwetshiwe kwe-bearing, kanye nokukhubazeka kwempahla ngokwayo kungaholela ekuxebukeni kwento eginqikayo.Umthwalo osindayo kanye nesimo sesivinini esikhulu sama-bearings ngesikhathi sokusetshenziswa isikhathi eside nakho kungenye yezizathu ezibalulekile zokuthwala ukukhathala.Ama-elementi agingqayo ajikeleza ngokuqhubekayo futhi ashelelezi emigwaqweni yomjaho yangaphakathi nengaphandle yeringi.Ukucaciswa okudlulele kubangela izakhi eziginqikayo ukuthi zithwale imithwalo yemvamisa ephezulu kanye nomthelela omkhulu ngesikhathi sokunyakaza.Ukwengeza, ukukhubazeka kwempahla ye-bearing ngokwayo kanye nokusetshenziswa okunwetshiwe kwe-bearing kuzodala Ibangela ukukhathala ukuxebuka kwe-bearing rolling elements.

Ukugqwala Ukwehluleka kokugqwala akuvamile.Ngokuvamile, kubangelwa ukwehluleka kwe-bearing end cover bolts ukuthi iqiniswe endaweni, okubangela ukuthi amanzi angene emotweni ngesikhathi sokusebenza, futhi i-lubricant ihluleke.I-motor ngeke isebenze isikhathi eside, futhi ama-bearings nawo azogqwala.Ukuhlanza ama-bearings agqwalile ngophalafini kungasusa ukugqwala.Ikheji likhululekile

Ikheji elixegayo lingaholela kalula ekushayisaneni nasekugugekeni phakathi kwekheji nezinto ezigoqayo ngesikhathi sokusebenza.Ezimweni ezimbi kakhulu, ama-rivets ekheji angase aphuke, okubangele ukuwohloka kwezimo zokugcoba futhi kubangele ukuthi i-bearing ibambelele.

Izizathu zomsindo ongavamile kuma-motor bearings kanye nokuhlaziywa kwezimbangela zomsindo "wokugubha" ovela ekhejini: Kubangelwa ukudlidliza nokungqubuzana phakathi kwekheji nezinto ezigoqayo.Kungenzeka kungakhathaliseki ukuthi hlobo luni lwamafutha.Ingakwazi ukumelana ne-torque enkulu, umthwalo noma imvume ye-radial.maningi amathuba okuthi zenzeke.Isixazululo: A. Khetha ama-bearings anemvume encane noma faka ukulayisha kuqala kuma-bearings;B. Yehlisa umthwalo wesikhashana futhi unciphise amaphutha okufaka;C. Khetha amafutha amahle.

Umsindo onkenenezayo oqhubekayo "ubhaza...": Ukuhlaziywa kwembangela: Isithuthuthu sikhipha umsindo ofana nokubhaza lapho sigijima ngaphandle komthwalo, futhi injini ithola ukudlidliza kwe-axial okungavamile, futhi kunomsindo "obhazayo" lapho ivula noma ivaliwe.Izici ezithile: izinjini eziningi zinezimo zokuthambisa ezingezinhle, futhi amabhola amabhola asetshenziswa kuzo zombili iziphetho ebusika.

Ukwenyuka kwezinga lokushisa: Izici ezithize: Ngemva kokuthi i-bearing iyasebenza, izinga lokushisa lidlula ububanzi obudingekayo.Ukuhlaziywa kwembangela: A. Amafutha amaningi kakhulu akhulisa ukumelana nokomisa;B. Ukuvunyelwa okuncane kakhulu kubangela umthwalo wangaphakathi owedlulele;C. Iphutha lokufaka;D. Ukungqubuzana kwezinto zokuvala;E. Ukuhuquzela kwamabhere.Isixazululo: A. Khetha amafutha afanele futhi usebenzise inani elifanele;B. Lungisa ukulayishwa kusengaphambili nokudidiyelwa kwemvume, futhi uhlole ukusebenza kwesiphetho samahhala;C. Ukuthuthukisa ukunemba kanye nendlela yokufaka isihlalo esinesihlalo;D. Thuthukisa ifomu lokuvala.Injini ivamise ukukhiqiza ukudlidliza, okubangelwa ikakhulukazi ukudlidliza okungazinzile okubangelwa ukudlidliza kwe-axial lapho ukusebenza kokuqondisa kweshaft kungalungile.Isixazululo: A. Sebenzisa amafutha ngokusebenza kahle kokugcobisa;B. Engeza ukulayisha kuqala ukuze unciphise amaphutha okufaka;C. Khetha ama-bearings ane-radial clearance encane;D. Thuthukisa ukuqina kwesihlalo esinemoto;E. Thuthukisa ukuqondanisa kokuthwala.

Ukugqwala kukapende: Ukuhlaziywa kwembangela: Ngenxa yokuthi uwoyela kapende ku-casing ene-motor casing uyoma, izingxenye zamakhemikhali eziguquguqukayo zonakalisa ubuso bokuphela, umsele ongaphandle kanye nomsele we-bearing, okubangela umsindo ongajwayelekile ngemva kokuba inkasa igqwalile.Izici ezithile: Ukugqwala endaweni ethwalayo ngemva kokugqwala kubi kakhulu kunasendaweni yokuqala.Isixazululo: A. Sula i-rotor ne-casing ngaphambi kokuhlanganisa;B. Yehlisa izinga lokushisa lemoto;C. Khetha imodeli efanelekayo ngopende;D. Thuthukisa izinga lokushisa le-ambient lapho ama-motor bearings abekwe khona;E. Sebenzisa amafutha afanelekile.Amafutha okugcoba abangela ukugqwala okuncane, futhi uwoyela we-silicone namafutha amaminerali cishe abangela ukugqwala;F. Sebenzisa inqubo yokucwilisa i-vacuum.

Umsindo ongcolile: Ukuhlaziywa kwesizathu: Okubangelwa ukuhlanzeka kwe-bearing noma igrisi, kuphuma umsindo ongajwayelekile ongajwayelekile.Izici eziqondile: umsindo uphakathi, awuvamisile ngevolumu kanye nevolumu, futhi uvela kaningi kumamotho anesivinini esikhulu.Isixazululo: A. Khetha amafutha amahle;B. Thuthukisa ukuhlanzeka ngaphambi komjovo wamafutha;C. Qinisa ukusebenza kokuvala uphawu;D. Ukuthuthukisa ukuhlanzeka kwendawo yokufaka.

Imvamisa ephezulu, umsindo wokudlidliza "chofoza...": Izici ezithile: Imvamisa yomsindo iyashintsha ngesivinini esithwalayo, futhi ukuvevezela okungaphezulu kwezingxenye kuyimbangela eyinhloko yomsindo.Isixazululo: A. Thuthukisa ikhwalithi yokucubungula indawo yomjaho othwele futhi unciphise i-waviness amplitude;B. Yehlisa amaqhubu;C. Lungisa ukulayishwa kusengaphambili nokulingana kwe-clearance, hlola ukusebenza kwesiphetho samahhala, futhi uthuthukise ukunemba kwe-shaft nesihlalo sokuthwala.indlela yokufaka.

I-bearing izwa kabi: Izici ezithize: Uma ubambe i-bearing ngesandla sakho ukuze uzungezise i-rotor, uzwa ukungcola nokuvinjelwa ku-bearing.Ukuhlaziywa kwesizathu: A. Ukugunyazwa ngokweqile;B. Ukungafani okungalungile kobubanzi obungaphakathi kanye ne-shaft;C. Ukulimala kwesiteshi.Isixazululo: A. Gcina imvume incane ngangokunokwenzeka;B. Ukukhethwa kwezindawo zokubekezelelana;C. Thuthukisa ukunemba futhi unciphise ukulimala kwesiteshi;D. Ukukhethwa kwamafutha.
