Kungani amabheringi ezimboni ehluleka ngokushesha ngenxa yokungalungi kahle?

• Ukungalungi kahle kuguqula ukuthintana okuvamile kokugoqa kube umthwalo onqenqemeni, okuphakamisa ukucindezeleka nokushisa.
• Imiklamo ezizilungisayo ingabekezelela amaphutha alinganiselwe e-angular kangcono kunezinhlobo zamabhere aqinile.
• Ukuqondanisa, ukuthambisa, ukulawula ukungcola, kanye nokuqina kwendlu kumele kulawulwe ndawonye.
• Isiqondiso se-ISO kanye nemboni sigcizelela ukunemba kokufakwa, hhayi nje izilinganiso zomthwalo wekhathalogi.
• Ukwehluleka kokuthwala okusheshayo kuvame ukuba yinkinga yesistimu, hhayi iphutha lomkhiqizo kuphela.

Ama-bearings ezimboni aklanyelwe ukuthwala umthwalo ngokuxhumana okugoqekayo okulawulwayo, kodwa ukungalungi kahle kuphazamisa lokho kwakheka kwesimo futhi kusheshiseukwehluleka kokuthwalaEkuhlolweni kwamabhere kanye nomkhuba wokuqondanisa umshini, ngisho nephutha elincane le-angular lingadala umthwalo wendawo ofinyeza impilo, ikakhulukazi kuma-motor kagesi asheshayo, amaphampu, ama-gearbox, kanye nama-conveyor drive. I-ISO 286-1 ichaza ukubekezelelana kobukhulu bokufakwa kwe-shaft kanye ne-hole, kuyilapho ukuqondanisa kanye nokuqinisekiswa kokugijima kuvame ukuphathwa ngemikhuba emihle yokwakha nokuhlanganisa imishini efanaI-ISO 20816-1ukuhlolwa kokudlidliza kanyeIsiqondiso seyunithi ye-NIST SIukuze kulinganiswe ukuhambisana. Uma umugqa wakho uqhubeka nokulahlekelwa ama-bearings kusenesikhathi, imbangela eyinhloko ngokuvamile akuyona isigaba sama-bearings uqobo, kodwa ukuxhumana phakathi kokulingana, ukuvumelanisa, umthwalo, kanye nokuthambisa.

Kungani ukungalungi kahle kubangela ukuthi ama-bearings ezimboni ahluleke ngokushesha

Ukungalungi kahle kubangela ukuthi amabheringi ezimboni ahluleke ngokushesha ngoba indlela yomthwalo iyasuka emgqeni ophakathi ohlosiwe webheringi futhi igxilise amandla onqenqemeni lokuxhumana okugoqekayo. Lokho kulayisha komphetho kwandisa ukucindezeleka kweHertzian, kuphakamisa izinga lokushisa lokusebenza, futhi kuphazamise ifilimu yokugcoba evame ukuhlukanisa izindawo zensimbi. Uma ifilimu kawoyela noma yamafutha isincipha, kuqala ukushelela okuncane kanye nokucindezeleka kobuso, okungaqhubekela phambili ekungcoleni, ekuqhekekeni, ekugugeni kwekheji, futhi ekugcineni kubambeke.

Ngokwendlela engokoqobo, i-bearing akudingeki "iphuke" ukuze ukwehluleka kuqale. I-bearing isengajikeleza ngenkathi i-geometry yayo yangaphakathi isivele igcwele ngokweqile. Yingakho ukwehluleka kokuqondanisa kuvame ukuvela njengomsindo, ukudlidliza, kanye nokushisa kukhuphuka ngaphambi kokuba i-bearing ivale ngempela. Ekugcinweni kwezimboni, lezo zimpawu zokuqala zibaluleke kakhulu kunomonakalo obonakalayo ngoba zembula iphethini yokuxhumana ngaphambi kokwehluleka okukhulu.

Indlela yokuhluleka inzima kakhulu emishinini ene-torque eguquguqukayo noma imijikelezo evamile yokuqalisa. Ngesikhathi sokusheshisa, i-shaft ingagoba kancane, i-housing ingaphambuka, futhi ukusatshalaliswa komthwalo kushintsha umzuzu nomzuzu. Lokho kusho ukuthi i-bearing ingaqondiswa kahle lapho ivalwa kodwa iqhubeke nokuhluleka ngokushesha ekusebenzeni ngoba ukungalungi kwangempela kubonakala kuphela ngaphansi komthwalo.

Kungakanani ukungalungi okungabekezelelwa ama-bearings ezimboni?

Ukubekezelelana kokungahambisani kuncike ohlotsheni lwebhereyi, indawo evulekile yangaphakathi, ukwakheka kwekheji, kanye nomthwalo wokusebenza. Izinhlobo zebhereyi eziqinile zibekezelela amaphutha amancane e-angular, kuyilapho imiklamo yokuzivumelanisa ngokwayo ingamunca okuningi ngoba izinto ezigoqekayo kanye nemigwaqo yomjaho kungaphinde kungene phakathi nendawo uma kuqhathaniswa nomgodi. Yingakho ukukhetha umndeni webhereyi ofanele kuyingxenye enkulu yokulawula ukungahambisani.

Isibonelo, ama-ball bearings azilungisayo avame ukusetshenziswa lapho ukuphambuka kwe-shaft noma ukungalungi kokufaka kungagwemeki, kuyilapho ama-roller bearings ayisilinda ekhethwa ngenxa yokuqina okuphezulu kwe-radial kodwa ngokuvamile adinga ukulungiswa okungcono. Ukukhetha okulungile akugcini nje ngokuba "okuqinile" noma "okukhulu"; yilowo ohambisana ne-alignment envelope yangempela yomshini.

Emsebenzini wokusebenza komshini osekelwe ezindinganisweni, i-bearing engcono kakhulu yileyo egcina ukuxhumana kwangaphakathi ngaphakathi kwe-envelope yokuklama kulo lonke uhla lokusebenza. Yingakho ama-OEM amaningi eqhathanisa uhlobo lwe-bearing, ukunemba kwendlu, kanye nokuqina kwe-shaft ndawonye esikhundleni sokwahlulela ngesilinganiso somthwalo wekhathalogi kuphela.

Lokho okwenziwa ukungalungi kahle ekugcotshweni nasekushiseni

Ukungalungi kahle konakalisa ukuthambisa ngoba kucindezela ukujiya kwefilimu ngokungalingani futhi kuphoqa i-bearing ukuthi ifinyelele ekuthambiseni komngcele ngokushesha. Ifilimu enempilo ye-elastohydrodynamic incike ku-geometry ezinzile, isivinini, i-viscosity, kanye nokusatshalaliswa komthwalo. Lapho umthwalo ugxila emaphethelweni, ifilimu iyawa endaweni futhi ukusebenzisana kwensimbi nensimbi kuyanda.

Ukushisa bese kuba yinkinga enkulu. Ukushiswa kwamafutha kuyanda ngokushisa, ukwehla kwe-viscosity kawoyela, futhi ukuphuma kwegazi kwamafutha kungaba okungajwayelekile. Lokhu kudala i-feedback loop: ukushisa okwengeziwe kunciphisa ukusebenza kahle kwamafutha, kanti ukushiswa okubuthakathaka kuvumela ukushisa okwengeziwe. Ezimweni eziningi zasensimini, i-bearing isolwa kuqala, kodwa ukulandelana kwangempela kuyiphutha le-geometry, bese kuba ukwehluleka kwamafutha, bese kuba umonakalo womphezulu.

Isifundo sokulungisa esisebenzayo silula: uma i-bearing ishisa kakhulu ngemva komsebenzi wokulungisa, ungacabangi ukuthi i-bearing “iphukile.” Hlola ukulungiswa kwe-shaft, ukuqina kwendlu, unyawo oluthambile, kanye nohlelo lokugcoba ngokushesha.

• Hlola ukulingana kwe-shaft kanye ne-housing ekushiseni kokusebenza uma kungenzeka.
• Qinisekisa uhlobo lwamafutha, inani lokugcwalisa, kanye nesikhathi sokuphinda kugcotshwe.
• Hlola izindlela zokungcola njengezivalo ezigugile noma ama-labyrinth owonakele.
• Qinisekisa ukuthi ibhere elifakiwe alilayishwa kusengaphambili ngokuphambuka.

Indlela onjiniyela abaxilonga ngayo ukwehluleka kwamabhereli okuhlobene nokungalungi kahle

Ukwehluleka kwebhereyi okuhlobene nokungalungi kutholakala ngokufunda iphethini yomonakalo, hhayi nje iphuzu lokugcina lokwehluleka. Iphethini yokuguguleka ivame ukukutshela ukuthi inkinga ivela ekufakweni, ukugoba kweshafu okuguquguqukayo, noma ukuphambuka kwendlu. Ekuhlaziyweni kokwehluleka, ochwepheshe bafuna ukupholisha umjaho ohlangothini olulodwa, izimpawu zokuhlikihla ikheji, umbala wokushisa ongalingani, kanye nokuwohloka kwamafutha.

Ukuhlaziywa kokudlidliza kungenye yamathuluzi asensimini awusizo kakhulu. I-ISO 20816-1 inikeza isiqondiso sokuhlola ukudlidliza komshini ngokulinganisa ubunzima bokudlidliza ezingxenyeni ezingajikelezi. Empeleni, ukwanda kwezingxenye ezithile zemvamisa, ikakhulukazi kanye nokwenyuka kwezinga lokushisa nomsindo, kuyinkomba enamandla yokuthi umshini unenkinga yokuqondanisa kunenkinga yomthwalo omsulwa.I-ISO 15243:2017futhi iwusizo ngoba ihlukanisa umonakalo wamabhere ajikelezayo futhi isiza amaqembu ukuchaza izindlela zokuhluleka njalo.

Uma umonakalo ugxile ohlangothini olulodwa lomgwaqo womjaho, ukungalungi kahle kuvame ukuba yingxenye yendaba. Uma umonakalo ufana kodwa ungcolile, khona-ke ukuhlelwa kahle kungase kube okwesibili. Ukuxazulula izinkinga okuhle kugwema iphutha elivamile lokushintsha amabheringi ngokuphindaphindiwe ngaphandle kokulungisa umthombo womshini.

Yimuphi umklamo wamabhere ongcono kakhulu lapho ukungalungi kahle kungenakugwenywa?

Umklamo omuhle kakhulu wokuthwala izinto ngokungafaneleki ngokuvamile yilowo ongabekezelela iphutha le-angular ngaphandle kokudilika kwesikhala sangaphakathi noma ukusatshalaliswa komthwalo. Emishinini eminingi yezimboni, lokho kusho ama-ball bearings azilungisa ngokwawo noma ama-roller bearings ayindilinga. Impendulo efanele incike ekutheni umshini udinga isivinini, ukuqina, ukumelana nokushaqeka, noma ukuqina.

Isibonelo, injini enesivinini esikhulu ingase ibeke phambili ukungqubuzana okuphansi nomsindo ophansi, okwenza ibhereyitha yebhola elizilungisayo ifaneleke kakhulu kunomklamo we-roller esindayo. Umshini wokuthutha noma wephepha, ngokuphambene, ungadinga ibhereyitha ye-roller eyindilinga ngoba ukumelana nomthwalo kanye nokushaqeka kubaluleke kakhulu kunokulahlekelwa ukungqubuzana. Uma isikhala sincane, ibhereyitha ye-roller yenaliti ingathwala umthwalo omningi, kodwa ayibekezeleli kangako uma i-housing noma i-shaft geometry imbi.

Ukukhetha kwangaphakathi kufanele futhi kucabangele ukwakheka kwesivalo, ukuhambisana kwe-lubricant, kanye nokushabalaliswa kokushisa. Uma uhlelo lokusebenza luqhubeka njalo, ngisho nenani elincane lokungahambisani kahle okuphindaphindiwe kungaba yinkinga enkulu yokunciphisa impilo phakathi nezinkulungwane zamahora okusebenza.

Kubathengi abaqhathanisa izinketho, amakhasi anjengeamabheringi ebhola elijulile, amabheringi ebhola azilungisa ngokwawo, futhiamabheringi e-roller ayindilingaziyizindawo zokuqala eziwusizo ngoba zimele amazinga ahlukene okubekezelela ukuhambisana kanye nomthamo womthwalo. Uma umshini unemithwalo ehlanganisiwe kanye nezidingo zokubeka kahle,amabheringi ebhola lokuxhumana eliyi-angularkungase kube ngcono ukulingana, kodwa kuphela uma ukuqondisa kungalawulwa kahle.

Amaphutha okufakwa avame kakhulu alula, kodwa imiphumela yawo iyabiza. Unyawo oluthambile, i-torque engalingani yebholithi, izindawo zokufaka ezingcolile, ukulingana okungalungile komgodi, kanye nezindawo zokugoba konke kudala ukungahambisani kahle ngaphambi kokuba umshini uqale. Uma ibhereyi icindezelwe ngaphansi kokuhlanekezela, ukuvuleka kwayo kwangaphakathi kanye ne-angle yokuxhumana kungenzeka ukuthi sekuvele kuphazamisekile.

1. Ungacabangi ukuthi indlu iyisicaba ngoba nje intsha.
2. Ungaphoqi i-bearing emgodleni ngezindlela zokushayisana ezilimaza imigwaqo yomjaho.
3. Ungakushayi indiva ukukhula kokushisa emigodini emide noma emishinini esebenza ngokushisa.
4. Ungahlanganisi izinqumo zokuvula kwangaphakathi kwamabherethi kanye nokulayisha kusengaphambili ngaphandle kokuhlola izinga lokushisa lokusebenza.
5. Ungashintshi ibhereyitha ngaphandle kokuhlola i-geometry yomshini ozungezile.

Ukulawula ukufakwa kubalulekile ngoba i-bearing ingasebenza kuphela ngaphakathi kwe-geometry enikezwe yona. Lokhu kubaluleke kakhulu kumakhasimende e-OEM, lapho ukuqina kwe-batch kanye nokuphindaphinda kokuhlanganiswa kungathinti nje kuphela impilo, kodwa futhi nomsindo, ukudlidliza, kanye nezindleko zewaranti.

Indlela yokuvimbela ukwehluleka kwamabhere ezimboni ekungalingani kahle

Ukuvimbela ukwehluleka kokuhlelwa kahle kudinga kokubili ukuzithiba kokuklama nokulungisa. Isu eliphumelela kakhulu ukunciphisa amathuba okuthi ibhereyi lizobona ukugcwala komthwalo okungalindelekile ngesikhathi sokuphila kwalo. Lokho kusho ukukhetha umndeni wamabhereyi ofanele, ukuklama indlu eqinile ngokwanele, nokuqinisekisa ukuhambisana kokusebenza kwangempela esikhundleni sokuthembela kuphela emidwebweni eqanjiwe.

Uhlelo lokuvimbela olusebenzayo kufanele luqale ngokulinganisa. Sebenzisa ukulungiswa kwe-laser noma ukulinganisa ngokunemba ngesikhathi sokufakwa, bese uhlola kabusha ngemva kokufudumala uma umshini usebenza ngokushisa. Engeza ukuthambekela kokudlidliza, ukuhlolwa kwezinga lokushisa, kanye nokubuyekezwa kwesimo samafutha ukuze ubambe ukukhukhuleka kusenesikhathi. Ukuze uthole izimpahla ezibalulekile, gcina amarekhodi amanani okulungiswa, uhlobo lwebhere, isigaba sokulingana, kanye nokushisa kokusebenza ukuze ukwazi ukuqhathanisa ukwehluleka namaphethini kunokuqagela.

Ezinhlelweni ezithwele kakhulu, ukukhetha izinto nakho kubalulekile. Ezinye izinsimbi ezithwalayo zikhiqizwa ukuze zihlanzeke kakhulu futhi zibe lukhuni ngoba izinto ezingezona ezensimbi zinganciphisa impilo yokukhathala. Njengereferensi, insimbi ethwalayo evamile njenge-AISI 52100 isetshenziswa kabanzi ngoba ingashiswa ibe cishe yi-60-66 HRC, isekela ukumelana nokukhathala okuphezulu uma ihlanganiswe ne-geometry efanele kanye nokugcotshwa. Lokho kusho ukuthi, ngisho nezinto ezinhle kakhulu azikwazi ukukhokhela ngokugcwele ukungalungi okungapheli.

Uma ukungalungi kahle empeleni kuyinkinga yokuklama uhlelo

Ukungalungi kahle ngezinye izikhathi kuyinkinga yokuklama kunokuba kube yinkinga yokuhlanganisa.
