Ama-Bearings yizingxenye ezisekela kakhulu zamamotho.Ngaphansi kwezimo ezijwayelekile, lapho izinga lokushisa lama-motor bearings lidlula i-95 ° C futhi izinga lokushisa lama-sliding bearings lidlula i-80 ° C, ama-bearings ashisa kakhulu.
Ukuthwala ukushisa ngokweqile lapho imoto isebenza kuyiphutha elivamile, futhi izimbangela zalo zihlukahlukene, futhi ngezinye izikhathi kunzima ukuxilonga ngokunembile, ngakho-ke ezimweni eziningi, uma ukwelashwa kungafiki ngesikhathi, umphumela uvame ukulimala kakhulu emotweni, okwenza injini Isikhathi sokuphila sifinyezwa, esithinta umsebenzi nokukhiqiza.Fingqa isimo esithile, izizathu kanye nezindlela zokwelashwa zokushisa kwemoto.
1. Izizathu nezindlela zokwelashwa zokushisa ngokweqile kwama-motor bearings:
1. I-rolling bear ifakwe ngokungalungile, ukubekezelelana okufanelekile kuqinile kakhulu noma kukhululekile kakhulu.
Isixazululo: Ukusebenza kokusebenza kwama-rolling bearings akuxhomekile kuphela ekunembeni kokukhiqiza kwe-bearing ngokwayo, kodwa futhi nokunemba kwe-dimensional, ukubekezelelana komumo kanye nokuqina kwendawo ye-shaft kanye nomgodi ohambisana nayo, ukulingana okukhethiwe nokuthi ukufakwa kulungile yini. noma cha.
Ngokuvamile amamotho avundlile, ama-bearings ahlanganiswe kahle athwala ingcindezi ye-radial kuphela, kodwa uma ukulingana phakathi kweringi yangaphakathi yebheringi ne-shaft kuminyene kakhulu, noma ukulingana phakathi kweringi yangaphandle yebheringi nesembozo sokugcina kuqine kakhulu. , okungukuthi, lapho ukubekezelelana kukhulu kakhulu, khona-ke ngemva komhlangano I-bearing clearance izoba yincane kakhulu, ngezinye izikhathi ngisho isondele ku-zero.Ukuzungezisa akuguquguquki kanje, futhi kuzokhiqiza ukushisa ngesikhathi sokusebenza.
Uma ukulingana phakathi kweringi yangaphakathi ephethe kanye ne-shaft kukhuluphele kakhulu, noma iringi yangaphandle ethwele kanye nesembozo sokugcina kuxege kakhulu, khona-ke iringi yangaphakathi ephethe kanye ne-shaft, noma iringi yangaphandle ephethe kanye nesembozo sokugcina, izozungeza isihlobo. komunye nomunye, kubangele ukungqubuzana nokushisa, okuholela ekuhlulekeni kokuzala.ukushisa ngokweqile.Ngokuvamile, indawo yokubekezelela ye-diameter yangaphakathi yeringi yangaphakathi ethwele njengengxenye yereferensi ihanjiswa ngezansi komugqa onguziro ezingeni elijwayelekile, futhi indawo yokubekezelela ye-shaft efanayo kanye nendandatho yangaphakathi ye-bearing form ukulingana okuqinile kakhulu. kunaleyo eyakhiwe ngembobo yereferensi evamile .
2. Ukukhetha okungalungile kwamafutha okugcoba noma ukusetshenziswa nokugcinwa ngendlela engafanele, amafutha okugcoba ampofu noma awonakele, noma axutshwe nothuli nokungcola kungabangela ukushisa.
Isixazululo: Ukwengeza amafutha amaningi kakhulu noma amancane kakhulu kuzokwenza ukuthi ukuthwala kushise, ngoba uma amafutha eningi, kuzoba nokungqubuzana okuningi phakathi kwengxenye ejikelezayo ye-bearing kanye namafutha, futhi lapho amafutha engeziwe. kuncane kakhulu, ukoma kungase kwenzeke Ukungqubuzana nokushisa.Ngakho-ke, inani lamafutha kufanele lilungiswe ukuze libe ngu-1/2-2/3 wevolumu yesikhala segumbi lokuthwala.Amafutha okugcoba angafaneleki noma awonakele kufanele ahlanzwe futhi esikhundleni sawo kufakwe amafutha ahlanzekile okugcoba.
3. Igebe le-axial phakathi kwesembozo sokuthwala sangaphandle senjini kanye nendilinga yangaphandle ye-rolling bear incane kakhulu.
Isixazululo: Ama-motor amakhulu namaphakathi ngokuvamile asebenzisa ama-ball bearing ekugcineni okungewona ama-shaft.Ama-roller bearings asetshenziswa ekupheleni kwesandiso se-shaft, ukuze kuthi lapho i-rotor ishisa futhi inwetshwa, ingakwazi ukwelula ngokukhululekile.Njengoba zombili iziphetho ze-motor encane zisebenzisa ama-ball bearings, kufanele kube negebe elifanele phakathi kwekhava elingaphandle elithwalayo kanye nendandatho yangaphandle ye-bearing, ngaphandle kwalokho, ukuthwala kungase kushise ngenxa yokuphakama okushisayo okweqile ku-axial direction.Lapho lesi simo senzeka, ikhava yangaphambili noma yangemuva kufanele isuswe kancane, noma iphedi elincane lephepha kufanele libekwe phakathi kwesembozo sokuthwala kanye nesembozo sokugcina, ukuze kwakhiwe isikhala esanele phakathi kwesembozo sokuthwala sangaphandle ekugcineni komunye. nendandatho yangaphandle yokuthwala.Ukusula.
4. Isembozo sokugcina noma ama-caps okuthwala ezinhlangothini zombili ze-motor awafakiwe kahle.
Isixazululo: Uma amakhava okugcina noma amakhava okuthwala ezinhlangothini zombili zenjini engafakwanga ngokuhambisana noma ama-seams angaqinile, amabhola azochezuka kuthrekhi futhi ajikelezise ukuze akhiqize ukushisa.Amakepisi okugcina noma amakepisi okuthwala kuzo zombili izinhlangothi kufanele aphinde afakwe ayisicaba, futhi azungeziswe ngokulinganayo futhi ahlanganiswe namabhawudi.
5. Amabhola, ama-roller, amasongo angaphakathi nangaphandle, namakheji amabhola aguge kakhulu noma ayaxebuka insimbi.
Isixazululo: I-bearing kufanele ishintshwe ngalesi sikhathi.
6. Ukuxhumeka okungalungile kokulayisha imishini.
Izizathu eziyinhloko yilezi: ukuhlanganiswa okungalungile kokuhlanganisa, ukudonsa ngokweqile kwebhande, ukungahambisani ne-axis yomshini wokulayisha, ububanzi obuncane kakhulu be-pulley, kude kakhulu nokuthwala i-pulley, i-axial ngokweqile noma umthwalo we-radial, njll. .
Isixazululo: Lungisa ukuxhumana okungalungile ukuze ugweme amandla angavamile ku-bheringi.
7. I-shaft igobile.
Isixazululo: Ngalesi sikhathi, amandla ekuthwaleni awasewona amandla e-radial ahlanzekile, abangela ukuthi i-bearing ishise.Zama ukuqondisa i-shaft egobile noma ubeke esikhundleni esisha
2. Indlela yokuvikela i-motor bear ekushiseni ngokweqile?
Kungabhekwa njengokungcwaba isici sokulinganisa izinga lokushisa eduze ne-bearing, bese ivikela ukuthwala ngokusebenzisa isifunda sokulawula.Landa Ngokuvamile, injini inesici sokulinganisa izinga lokushisa (njenge-thermistor) ngaphakathi kwe-motor, bese izintambo ezi-2 ziphuma ngaphakathi ukuze zixhumeke kusivikeli esikhethekile, futhi isivikeli sithumela i-voltage engu-24V engaguquki, lapho injini ithwala Nini. ukushisa ngokweqile kudlula inani elibekiwe lomvikeli, lizokhubeka futhi lidlale indima yokuvikela.Njengamanje, iningi labakhiqizi bezimoto ezweni basebenzisa le ndlela yokuvikela.
