I-Rolling bearing iyingxenye ebalulekile yemishini.Ukuthi ukusebenza kwe-motor kungenziwa ngokugcwele kuncike ekutheni ukuthwala kugcotshwe kahle yini.Kungashiwo ukuthi ukugcoba kuyisimo esidingekayo ukuze kuqinisekiswe ukusebenza okujwayelekile kokuthwala.Kubalulekile ekuthuthukiseni umthamo wokuthwala nokusetshenziswa kwe-bearing.Ubude besikhathi sokuphila budlala indima ebalulekile.Motor ezithwalaamamodeli ngokuvamile agcotshwa ngamafutha, kodwa aphinde agcotshwe ngamafutha.1 Inhloso yokugcoba Inhloso yokuthwala ukuthambisa ukwenza ifilimu kawoyela elincanyana phakathi kwendawo eginqikayo noma indawo eshelelayo ukuvimbela ukuthintana kwensimbi eqondile.Ukuthambisa kunciphisa ukungqubuzana phakathi kwezinsimbi futhi kubambezele ukugqokwa kwazo;ukwakheka kwefilimu yamafutha kwandisa indawo yokuxhumana futhi kunciphisa ukucindezeleka kokuxhumana;iqinisekisa ukuthi i-rolling bearing ingasebenza ngokujwayelekile isikhathi eside ngaphansi kokucindezeleka kokuxhumana kwe-high-frequency futhi yandise impilo yokukhathala;iqeda ukushisa okungqubuzanayo futhi inciphisa Ukushisa kwendawo yokusebenza ye-bearing kungavimbela ukushisa;ingavimbela uthuli, ukugqwala nokugqwala.Ukugcotshwa kukawoyela kulungele ama-bearings anesivinini esikhulu futhi kungamelana nezinga elithile lokushisa eliphezulu, futhi kudlala indima ekwehliseni ukudlidliza okuthwele nomsindo.

Ukugcotshwa kukawoyela kucishe kuhlukaniswe kwaba: 3.3 Ukuthambisa kwe-Splash Ukuthambisa kwe-splash kuyindlela evamile yokugcoba yokugingqa amabhere kumagiya avaliwe.Isebenzisa izingxenye ezijikelezayo, njengamagiya neziphonsa zikawoyela, ukuze ifafaze uwoyela wokugcoba.Gcoba ku-bearing noma ugeleze ungene ku-oyili oklanywe ngaphambili eduze kodonga lwebhokisi ukuya ku-rolling bear ukuze ugcobe i-bhering eligoqayo, futhi uwoyela wokugcoba osetshenzisiwe ungaqoqwa ebhokisini bese ugaywa kabusha ukuze usetshenziswe kabusha.Ngenxa yokuthi ama-rolling bearings awadingi noma yiziphi izindawo ezisizayo lapho kusetshenziswa i-splash lubrication, avame ukusetshenziswa kumagiya alula futhi ahlangene.Kodwa-ke, amaphuzu amathathu alandelayo kufanele anakwe lapho usebenzisa i-splash lubrication: 1) Izinga lamafutha okugcoba akufanele libe phezulu kakhulu, ngaphandle kwalokho ukusetshenziswa kukawoyela we-churning kuzoba kukhulu kakhulu, futhi uwoyela uzokhishwa.I-orifice iconsa amafutha ku-bearing ukuze igcobe i-bearing.Inani lamafutha elisetshenziswa empandeni ye-orifice lingashintshwa.Inzuzo yale ndlela yokugcoba yile: isakhiwo esilula, kulula ukuyisebenzisa;ububi buwukuthi: i-viscosity akulula ukuba ibe phezulu kakhulu, ngaphandle kwalokho ukudonsa kwamafutha ngeke kube bushelelezi, okuzothinta umphumela wokugcoba.Ngakho-ke, ngokuvamile isetshenziselwa ukugcoba ama-bearings aginqikayo ngesivinini esiphansi nomthwalo omncane.

Ukugcoba okugeza uwoyela kubizwa nangokuthi i-oil-immersion lubrication, okuwukucwilisa ingxenye ethwalayo emafutheni okugcoba, ukuze ingxenye ngayinye egoqayo ye-bearing ingene kuwoyela wokugcoba kanye ngesikhathi sokusebenza, futhi ilethe amafutha okugcoba kwezinye izingxenye zokusebenza. ukuthwala.Uma ucabangela ukulahlekelwa okuvusa amadlingozi nokukhuphuka kwezinga lokushisa, ukuze unciphise isivinini sokuguga samafutha okugcoba, kunzima ukusebenzisa i-lubrication yokugeza amafutha kuma-bearings ahamba ngesivinini.I-sediment echibini, njengemfucumfucu eqhumayo, ilethwa engxenyeni ethwalayo, ibangele ukuguga.I-2) Amafutha okugcoba ebhokisini kufanele ahlale ehlanzekile, futhi i-adsorber kazibuthe ingasetshenziswa echibini lamafutha ukuze kukhishwe udoti olimazayo kanye nodaba lwangaphandle ngesikhathi ukuze kuncishiswe ukuvela kokugqoka kwe-abrasive.3) Ekwakhiweni kwesakhiwo, ithangi lokugcina uwoyela kanye ne-orifice eholela ekuthwaleni kungenziwa odongeni lwethangi, ukuze ukuthwala kugcotshwe kubhavu kawoyela noma ku-oyela aconsayo, futhi ukuthambisa kungagcwaliswa ukuvimbela ukungalingani. ukunikezwa kwamafutha.Ukugcotshwa kokujikeleza kwamafutha Ukugcotshwa kwe-oil circulation kuyindlela yokugcoba izingxenye ezithwalayo eziginqikayo.Isebenzisa iphampu kawoyela ukumunca uwoyela wokugcoba ethangini likawoyela, iwafake esihlalweni esiginqikayo ngepayipi likawoyela nembobo kawoyela, bese ibuyisela uwoyela ethangini likawoyela ngokusebenzisa imbobo yokubuyisela uwoyela yesihlalo esiphethe, bese uyisebenzisa ngemva kokupholisa nokuhlunga.Ngakho-ke, lolu hlobo lwendlela yokugcoba lungakhipha ukushisa kwe-friction ngokuphumelelayo ngenkathi isusa ukushisa okwengeziwe, ngakho-ke ifaneleka ukuthwala izisekelo ezinomthwalo omkhulu kanye nesivinini esikhulu.

Ukugcotshwa komjovo kawoyela kuwuhlobo lokuthambisa lokujikeleza kukawoyela.Kodwa-ke, ukuze uvumele uwoyela wokugcoba ukuthi ungene ngokugcwele endaweni enyakazayo ehlobene yangaphakathi yebheringi enesivinini esikhulu, futhi ngesikhathi esifanayo ugweme ukukhuphuka kwezinga lokushisa ngokweqile kanye nokumelana nokungqubuzana okukhulu ngenxa yokutholakala kukawoyela ojikelezayo ngokweqile ngaphansi kwezimo zokusebenza ezinesivinini esikhulu, uwoyela ujovwa esihlalweni sokuthwala.I-nozzle yengezwa echwebeni, futhi umfutho wokunikezwa kwamafutha uyakhuphuka, futhi amafutha afafazwa ku-bearing nge-nozzle ukuze kuzuzwe ukugcotshwa nokupholisa kwe-bearing.Ngakho-ke, ukugcotshwa komjovo kawoyela kuyindlela enhle yokugcoba, esetshenziselwa ikakhulukazi ama-bearings anesivinini esikhulu, futhi ingasetshenziswa ezikhathini lapho inani le-dmn ye-rolling bearing likhulu kuno-2000000mm·r/min.Ingcindezi yephampu kawoyela yokugcotshwa komjovo kawoyela imvamisa iba ngamabha ama-3 kuye kwangama-5.Ukuze unqobe futhi ugweme umphumela we-Coanda ngaphansi kwezimo zesivinini esikhulu, isivinini sokujova uwoyela endaweni yokukhipha umlomo wombhobho kufanele sifinyelele ngaphezu kuka-20% wejubane eliwumugqa webheringi egingqikayo.

Ukugcotshwa kwenkungu kawoyela kuwuhlobo lokuthambisa lwenani elincane, olusebenzisa inani elincane likawoyela wokugcoba ukuze kuhlangatshezwane nezidingo zokuthambisa zamabhering agingqikayo.Ukugcoba inkungu kawoyela ukushintsha uwoyela wokugcoba ube yinkungu kawoyela kujeneretha yenkungu kawoyela, bese ugcoba i-bearings ngenkungu kawoyela.Njengoba inkungu kawoyela ijiya ibe amaconsi kawoyela endaweni esebenzayo yebhering egingqikayo, empeleni i-rolling bear isagcina isimo sokugcotshwa kukawoyela omncane.Lapho isivinini somugqa wesici esiginqikayo sesithelo siphezulu kakhulu, ukuthambisa kwenkungu kawoyela kuvame ukusetshenziselwa ukugwema ukwanda kokungqubuzana kwangaphakathi kukawoyela kanye nokwenyuka kwezinga lokushisa elisebenzayo lebhering eliginqikayo ngenxa yokunikezwa kukawoyela ngokweqile kwezinye. izindlela zokugcoba.Ngokuvamile, ingcindezi yenkungu kawoyela icishe ibe ngu-0.05-0.1bar.Kodwa-ke, amaphuzu amabili alandelayo kufanele anakwe lapho usebenzisa le ndlela yokugcoba: 1) I-viscosity yamafutha akufanele ibe ngaphezu kuka-340mm2 / s (40 ° C), ngoba umphumela we-atomization ngeke uzuzwe uma i-viscosity. iphakeme kakhulu.2) Inkungu kawoyela egcotshiwe ingase ihlakazeke kancane emoyeni futhi ingcolise imvelo.Uma kunesidingo, sebenzisa isihlukanisi sikawoyela negesi ukuze uqoqe inkungu kawoyela, noma usebenzise idivayisi yokukhipha umoya ukuze ususe igesi yokukhipha umoya.

I-oil-air lubrication isebenzisa i-piston-type distributor quantitative, ethumela inani elincane lamafutha ekugelezeni komoya ocindezelwe epayipini ngezikhathi ezithile, okwenza ukugeleza okuqhubekayo kwamafutha odongeni lwepayipi futhi kunikezwa ekuthwaleni.Njengoba amafutha okugcoba amasha evame ukuphakelwa, amafutha ngeke aguge.Umoya ocindezelwe wenza kube nzima ukuthi ukungcola kwangaphandle kungene ngaphakathi kwendawo yokuthwala.Inani elincane likawoyela linciphisa ukungcola endaweni ezungezile.Uma kuqhathaniswa nokugcotshwa kwenkungu kawoyela, inani lamafutha ekugcobiseni komoya kawoyela liyancipha futhi lizinzile, i-torque yokushayisana incane, futhi izinga lokushisa liphansi.Ifaneleka ngokukhethekile kumabheringi anesivinini esikhulu.
