Imibuzo Evame Ukubuzwa

Amaphutha wezigaba ezintathu zama-asynchronous motors ngokuvamile angahlukaniswa abe izingxenye ezimbili: amaphutha kagesi kanye namaphutha emishini.
Amaphutha emishini ahlanganisa: ama-bearings angalingani kahle noma awonakele, imikhono enemikhono, amakepisi kawoyela, ama-end cap, amafeni, izihlalo nezinye izingxenye, kanye nokuguga kwezingxenye ze-shaft.Amaphutha kagesi ikakhulukazi ahlanganisa: ukuphuka kwe-stator ne-rotor, phakathi kokujika (isigaba), ukuya phansi, njll.

I-stator ne-rotor zenziwe ngamashidi ensimbi e-silicon avaleleke futhi ayingxenye yesekethe kazibuthe yenjini.Ukulimala nokuguqulwa kwe-stator kanye ne-rotor cores kubangelwa ikakhulukazi izici ezilandelayo.
(1) Ukuguga ngokweqile noma ukuhlangana okungekuhle, okuholela ekuhlikihleni kwe-stator ne-rotor, okubangela umonakalo ongaphezulu, okubuye kubangele ukujikeleza okufushane phakathi kwezingcezu zensimbi ye-silicon, okwandisa ukulahleka kwensimbi yenjini, okwenza izinga lokushisa lemoto likhuphuke nalo. okusezingeni eliphezulu, lapho ukusetshenziswa kwefayela elihle namanye amathuluzi ukususa Burr, susa Silicon steel ucezu uxhumano iDemo, uhlanze bese camera ngopende insulating, futhi ukufudumeza futhi omiswe.
(2) Ingaphezulu le-iron core ligqwalile ngenxa yomswakama nezinye izizathu, kufanele lipholishwe nge-sandpaper, lihlanzwe futhi lifakwe ngopende wokuvikela.
(3) Umnyombo noma amazinyo ashile ngenxa yokushisa okuphezulu okukhiqizwa ngokumisa ukujikajika.Ithuluzi elifana neshizolo noma i-scraper lingasetshenziswa ukususa izinto ezincibilikisiwe futhi zomiswe ngopende wokuvikela.
(4) Inhlanganisela phakathi kwengqikithi nesisekelo somshini ikhululekile, futhi izikulufu zokubeka zangempela zingaqiniswa.Uma izikulufu zokumisa zingaphumeleli, phinda ubhoboze izimbobo zokubeka bese uthepha kusisekelo somshini, qinisa izikulufu zokubeka indawo.

Lapho i-rolling bear ishoda ngamafutha, kuzozwakala umsindo wamathambo.Uma kuzwakala umsindo wokulandelana oqhubekayo, kungase kube ukugqashuka kweringi yensimbi ethwele.Uma ukuthwala kuxubene nesihlabathi nezinye izinsalela noma izingxenye ezithwalayo zinokuguga okukhanyayo, kuzokhipha umsindo omncane.Hlola ngemva kokuhlakaza: qala uhlole umzimba oginqikayo webhere, ngaphakathi nangaphandle kweringi yensimbi ukuze kubonakale umonakalo, ukugqwala, izibazi, njll. Bese ucindezela iringi yangaphakathi yebheriyo ngesandla sakho wenze izinga lokuthwala, phusha iringi yensimbi yangaphandle. ngesinye isandla sakho, uma ukuthwala kuhle, indandatho yensimbi yangaphandle kufanele ijikeleze ngokushelelayo, akukho ukudlidliza kanye nokugxuma okusobala ekujikelezeni, akukho ukuhlehla kwendandatho yensimbi yangaphandle ngemva kokuma, ngaphandle kwalokho ukuthwala ngeke kusakwazi ukusetshenziswa.Isandla sokunxele sibhajwe eringini yangaphandle, isandla sokudla sincinza iringi yensimbi yangaphakathi, phoqa ukuphusha macala onke, uma uzizwa ukhululeke kakhulu lapho uphusha, kuwukugqokwa okungathi sína.

Iphutha ukulungisa ezithwele surface ukugqwala amabala atholakalayo 00 sandpaper Sula, bese singene yokuhlanza uphethiloli;ephethe imifantu, ngaphakathi nangaphandle kweringi ephukile noma ethwala ukuguga ngokweqile, kufanele kushintshwe ama-bearings amasha.Lapho ushintsha i-bearing entsha, sebenzisa uhlobo olufanayo lokuthwala njengelokuqala.Ukuhlanza nokufaka amafutha.

Ukuthwala inqubo yokuhlanza: qala ngokukhuhla uwoyela wemfucuza ebusweni bebhola lensimbi;sula amafutha emfucumfucu asele ngendwangu kakotini;bese ucwilisa i-bearing kuphethiloli bese ukhuhla ibhola lensimbi ngebhulashi;bese uhlanza ibhere ngophethiloli ohlanzekile;ekugcineni ubeke i-bearing ephepheni ukwenza uphethiloli uhwamuke futhi wome.

Ukuthwala inqubo yokugcoba: Ukuze kukhethwe i-rolling bearing grease, ukucatshangelwa okuyinhloko yizimo zokusebenza zokuthwala, ezifana nokusetshenziswa kwemvelo (okumanzi noma okomile), izinga lokushisa lokusebenza kanye nesivinini semoto.Umthamo wamafutha akufanele udlule u-2/3 wevolumu yekamelo lokuthwala.
Uma ufaka amafutha okugcoba ekuthwaleni, amafutha kufanele afakwe ohlangothini olulodwa lwe-bearing bese uwoyela oweqile kufanele ususwe kancane ngomunwe, inqobo nje uma uwoyela ungengezwa kuze kube yilapho ekwazi ukuvala ibhola lensimbi ngokuqinile. .Uma wengeza amafutha okugcoba embozweni yokuthwala, ungangezi kakhulu, cishe u-60-70% wanele.

(1) ukugoba kushaft uma ukugoba kungekukhulu, kungakhandwa ngokugaya shaft ububanzi, indandatho yokushelela;uma ukugoba kungaphezu kuka-0.2mm, i-shaft ingafakwa ngaphansi komshini wokunyathelisa, ekulungisweni kwengcindezi yokugoba, ukulungiswa kwendawo ye-shaft nge-lathe cutting grinding;njengokugoba kukhulu kakhulu isidingo sokushintshwa yi-shaft entsha.
(2) Ukugqoka kwentamo ye-shaft ukugqokwa kwentamo akukuningi, kungaba entanyeni yongqimba lwe-chromium plating, bese kugaywa kusayizi odingekayo;ukugqoka okungaphezulu, kungaba entanyeni ye-welding yokumbondela, bese kuthi ku-lathe cutting nokugaya;uma ukugqoka kwejenali kukhulu kakhulu, futhi kujenali ka-2-3mm, bese uvula umkhono ngenkathi kushisa kusethwe kujenali, bese uphendukela kusayizi odingekayo.
Ukujula kwe-shaft noma ukuqhekeka kwe-shaft transverse crack akudluli u-10% -15% wobubanzi be-shaft, ukuqhekeka kwe-longitudinal akudluli u-10% wobude be-shaft, kungalungiswa ngendlela yokushisela imbondela, bese ijika kahle ibe usayizi odingekayo.Uma ukuqhekeka ku-shaft kubi kakhulu, i-shaft entsha iyadingeka.

Uma kukhona imifantu endlini kanye nesembozo sokugcina, kufanele kulungiswe nge-overlay welding.Uma ukucaciswa kwe-bearing bore kukhulu kakhulu, okubangela ukuthi ikhava yokuphela kwe-bearing ibe yinde kakhulu, udonga lwe-bearing bore lungashiswa ngokulinganayo ngokusebenzisa i-punch, bese ukuthwala kungafakwa embozweni yokugcina, kanye nama-motors. ngamandla amakhulu, ubukhulu obudingekayo bokuthwala kungenziwa ngomshini ngokufaka inlaying noma ukucwenga.

Isisekelo sokufakwa kwemoto akulona izinga.Linganisa isisekelo se-motor futhi usilungise ngokuqinile ngemva kokulinganisa isisekelo.
Okokusebenza akugxilile ekuxhumekeni kwemoto.Lungisa kabusha ukugxila.
I-rotor ye-motor ayilingani.Ukulinganisa okuqinile noma okuguquguqukayo kwe-rotor.
I-pulley yebhande noma i-coupling ayilingani.I-Pulley noma i-coupling calibration balancing.
Ikhanda le-rotor shaft eligobile noma i-pulley eccentric.Qondisa i-rotor shaft, setha i-pulley iqonde bese usetha isethi ukuze ujike kabusha.

Uxhumo olungalungile lwe-stator winding, isifunda esifushane sendawo noma indawo ephansi, okuholela ekungalinganisweni kwamanje kwezigaba ezintathu nokubangela umsindo.
Udaba lwangaphandle noma ukungabi khona kwamafutha okugcoba ngaphakathi kwebheringi.Hlanza ama-bearings bese ufaka okokugcoba okusha kwe-1/2-1/3 yegumbi lokuthwala.
Ukuhamba okuxekethile phakathi kwe-stator nezindlu noma i-rotor core kanye ne-rotor shaft.Hlola isimo sokuguga sokulingana, ukushisela kabusha, ukucubungula.
I-Stator ne-rotor ukuhlikihla okungamanga.Thola indawo ephakeme ye-iron core, ukugaya ukucubungula.
Umsindo we-electromagnetic ngesikhathi sokusebenza kwemoto.Kunzima ukuqeda ngokulungisa.

① i-viscosity ephansi, okuqukethwe okuqinile okuphezulu kanye nokucwiliswa kalula.
② ukwelapha ngokushesha, ukubopha okuqinile nokunwebeka.
③Izakhiwo zikagesi eziphezulu, ukumelana nokushisa, ukumelana nomswakama kanye nokuzinza kwamakhemikhali.

a) Igebe leshaft nethayela lincane kakhulu.
b) Ukuvuleka kwesinye amafutha amancane kanye nokudla okunganele kwamafutha.
c) izinga lokushisa eliphezulu lamafutha okugcoba.
d) Ukulimala kocwaningo lwethayela lomphini.
e) ukubuyiswa kwamafutha ampofu kanye nokudla okunganele kwamafutha.
