I-rolling bearing yinto ebalulekileyo yomatshini.Ingaba ukusebenza kwemoto kunokuqhutywa ngokupheleleyo kuxhomekeke ekubeni ukuthwala kufakwe i-lubricated ngokufanelekileyo.Kunokuthiwa ukuba i-lubrication yimeko efunekayo yokuqinisekisa ukusebenza okuqhelekileyo kokuthwala.Kubalulekile ekuphuculeni umthamo wokuthwala kunye nokusetyenziswa kwe-bearing.Ubomi bunendima ebalulekileyo.Ukuthwala imotoiimodeli ngokubanzi zithanjiswa ngegrisi, kodwa zikwathanjiswa ngeoyile.1 Injongo yokuthambisa Injongo yokuthwala i-lubrication kukwenza ifilimu yeoli ebhityileyo phakathi kwendawo eqengqelekayo okanye isilayidi ukuthintela ukudibana ngokuthe ngqo kwentsimbi.Ukuthambisa kunciphisa ukungqubana phakathi kwesinyithi kwaye kunciphise ukunxiba kwazo;ukubunjwa kwefilimu yeoli kwandisa indawo yoqhagamshelwano kunye nokunciphisa uxinzelelo loqhagamshelwano;iqinisekisa ukuba i-rolling bearing ingasebenza ngokuqhelekileyo ixesha elide phantsi koxinzelelo loqhagamshelwano oluphezulu kunye nokwandisa ubomi bokukhathala;kuphelisa ukushisa okukhuphisanayo kunye nokunciphisa Ukushisa kwendawo yokusebenza yokuthwala kunokuthintela ukutshisa;inokuthintela uthuli, umhlwa kunye nomhlwa.I-oyile yokuthambisa ifanelekile kwiibheringi zesantya esiphezulu kwaye inokumelana neqondo elithile lobushushu obuphezulu, kwaye ikwadlala indima ekunciphiseni ukungcangcazela kunye nengxolo.

Ukuthanjiswa kwe-oyile kuqikelelwa ukuba yahlulwe ngokwe: 3.3 Ukuthambisa kwe-Splash Ukuthambisa kwe-Splash yindlela eqhelekileyo yokuthambisa iibheringi eziqengqelekayo kwiigesi ezivaliweyo.Isebenzisa iindawo ezijikelezayo, ezinje ngegiya kunye nezigaleli zeoyile, ukutshiza ioyile yokuthambisa.Gcoba kwibheringi okanye ungene kwi-oyile eyilwe ngaphambili ecaleni kodonga lwebhokisi ukuya kwi-rolling bear ukuze uthambise i-rolling bear, kwaye i-oyile yokuthambisa esetyenzisiweyo ingaqokelelwa kwibhokisi kwaye iphinde isetyenziswe kwakhona.Ngenxa yokuba iibheringi eziqengqelekayo azifuni naziphi na izixhobo ezincedisayo xa kusetyenziswa i-lubrication ye-splash, zihlala zisetyenziselwa ukuhanjiswa kwegiya elula kunye ne-compact.Nangona kunjalo, ezi ngongoma zintathu zilandelayo kufuneka ziqwalaselwe xa usebenzisa i-lubrication ye-splash: 1) Inqanaba leoli lokuthambisa akufanele libe phezulu kakhulu, ngaphandle koko ukusetyenziswa kweoli ye-churning kuya kuba kukhulu kakhulu, kwaye ioli iya kuchithwa.I-orifice ithontsiza i-oyile kwi-bearing ukuthambisa i-bearing.Ubungakanani beoli esetyenziswe kwingcambu ye-orifice inokulungiswa.Inzuzo yale ndlela yokuthambisa kukuba: isakhiwo esilula, kulula ukuyisebenzisa;into engalunganga kukuba: i-viscosity ayilula ukuba iphakame kakhulu, ngaphandle koko i-oyile ithontsiza ayiyi kuba lula, eya kuchaphazela umphumo wokuthambisa.Ke ngoko, ngokuqhelekileyo isetyenziselwa ukuthambisa iibheringi eziqengqelekayo ngesantya esiphantsi kunye nomthwalo olula.

Ukuthanjiswa kwe-oyile yokuhlambela kukwabizwa ngokuba yi-oyile-immersion lubrication, okukuntywilisela indawo ethwele ioyile yokuthambisa, ukuze into nganye eqengqelekayo yokuthwala ingene kwi-oyile yokuthambisa kanye ngexesha lokusebenza, kwaye izise ioyile yokuthambisa kwezinye iindawo ezisebenzayo. ukuthwala.Ukuqwalasela ilahleko evuselelayo kunye nokunyuka kweqondo lokushisa, ukwenzela ukunciphisa isantya sokuguga kweoli yokuthambisa, kunzima ukusebenzisa i-oyile yokuhlamba i-oyile kwiibheringi zesantya esiphezulu.I-sediment echibini, njenge-debris e-abrasive, iziswa kwi-bearing part, ibangela ukuguga.I-2) Ioli yokuthambisa kwibhokisi kufuneka ihlale icocekile, kwaye i-adsorber yamagnetic ingasetyenziselwa kwi-oyile ye-oyile ukususa i-debris e-abrasive kunye nezinto zangaphandle ngexesha lokunciphisa ukuvela kwe-abrasive wear.3) Kuyilo lwesakhiwo, itanki yokugcina i-oyile kunye ne-orifice ekhokelela ekuthwaleni inokusetwa eludongeni lwetanki, ukuze ukuthwala kufakwe i-lubrication kwindawo yokuhlambela ioyile okanye ioyile ethontsizayo, kwaye i-lubrication inokuzaliswa ukunqanda ukungonelanga. unikezelo lweoyile.Ukuthanjiswa kwe-oyile Ukujikeleza kwe-oyile yindlela yokuthambisa i-oyile ejikelezayo.Isebenzisa impompo yeoli ukufunxa ioyile yokuthambisa kwitanki yeoli, ingenise kwisitulo esiqengqelekayo ngombhobho weoyile kunye nomngxuma weoyile, emva koko ibuyisele ioyile kwitanki yeoli ngezibuko lokubuya kweoyile yesitulo esithweleyo, kwaye ke uyisebenzise emva kokupholisa nokuhluza.Ke ngoko, olu hlobo lwendlela yokuthambisa inokukhupha ngokufanelekileyo ubushushu be-friction ngelixa isusa ubushushu obuninzi, ngoko ilungele ukuthwala izixhaso ezinomthwalo omkhulu kunye nesantya esiphezulu.

Ukuthanjiswa kwenaliti ye-oyile luhlobo lokuthambisa ioyile yokujikeleza.Nangona kunjalo, ukuze uvumele ioyile yokuthambisa ingene ngokupheleleyo kwindawo eshukumayo yangaphakathi yesantya esiphezulu, kwaye kwangaxeshanye uthintele ukunyuka kwamaqondo obushushu agqithisileyo kunye nokumelana okugqithisileyo ngenxa yonikezelo lweoyile ejikelezayo kakhulu phantsi kweemeko ezisebenza ngesantya esiphezulu, i-oyile itofwa kwisitulo sokuthwala.I-nozzle yongezwa kwi-port, kwaye uxinzelelo lwe-oyile luyanda, kwaye i-oyile ifafazwe kwi-bearing nge-nozzle ukufezekisa i-lubrication kunye nokupholisa kwe-bearing.Ngoko ke, i-oil injection lubrication iyindlela efanelekileyo yokuthambisa, isetyenziselwa ikakhulu kwi-high-speed rolling bearings, kwaye ingasetyenziselwa kwiimeko apho ixabiso le-dmn ye-rolling bearing inkulu kune-2000000mm·r/min.Uxinzelelo lwempompo yeoyile yokuthambisa inaliti yeoyile ngokuqhelekileyo malunga ne-3 ukuya kwi-5 bar.Ukuze uphumelele kwaye ugweme isiphumo se-Coanda phantsi kweemeko zesantya esiphezulu, isantya sokutofa kwe-oyile kwindawo yokukhupha umlomo kufuneka sifikelele ngaphezu kwe-20% yesantya somgca we-rolling bear.

I-oyile inkungu yokuthambisa luhlobo lokuthambisa lobungakanani obuncinci, obusebenzisa i-oyile encinci yokuthambisa ukuhlangabezana neemfuno zokuthambisa iibheringi eziqengqelekayo.Ukuthanjiswa kwe-oyile inkungu kukuguqula ioyile yokuthambisa ibe yinkungu yeoyile kwijenereyitha yenkungu yeoyile, kunye nokuthambisa ukuthwala ngeoyile.Ukusukela ukuba inkungu yeoyile ijiya ibe ngamathontsi e-oyile kumphezulu wokusebenza webheringi eqengqelekayo, eneneni i-rolling bear igcina imo yokuthambisa ioyile.Xa isantya somgca wento eqengqelekayo yokuthwala iphezulu kakhulu, ukuthanjiswa kwe-oyile yinkungu isoloko isetyenziselwa ukuthintela ukonyuka koxinzelelo lwangaphakathi lweoyile kunye nokwanda kobushushu obusebenzayo bebhere eqengqelekayo ngenxa yonikezelo lweoyile ngokugqithisileyo kwezinye. iindlela zokuthambisa.Ngokubanzi, uxinzelelo lwenkungu yeoyile imalunga ne-0.05-0.1bar.Nangona kunjalo, ezi ngongoma zimbini zilandelayo kufuneka ziqwalaselwe xa usebenzisa le ndlela yokuthambisa: 1) I-viscosity yeoli kufuneka ingabi ngaphezu kwe-340mm2 / s (40 ° C), kuba umphumo we-atomization awuyi kufumaneka ukuba i-viscosity. iphezulu kakhulu.2) Inkungu ye-oyile ethambisayo isenokuchithakala ngokuyinxenye nomoya kwaye ingcolise imo engqongileyo.Ukuba kuyimfuneko, sebenzisa i-oyile kunye ne-gas separator ukuqokelela inkungu yeoli, okanye sebenzisa isixhobo sokungenisa umoya ukususa igesi yokukhupha.

I-oil-air lubrication ithatha i-piston-type distributor quantitative, ethumela i-oyile encinci kwi-air compressed flow flow kumbhobho ngamaxesha aqhelekileyo, okwenza ukuhamba kweoli eqhubekayo kudonga lombhobho kunye nokubonelela kwi-bearing.Kuba ioyile entsha yokuthambisa ihlala yondliwa kuyo, ioyile ayizukuguga.Umoya oxinanisiweyo wenza kube nzima ukuba ukungcola kwangaphandle kungene ngaphakathi kwendawo yokuthwala.Umthamo omncinci we-oyile unciphisa ungcoliseko kwindawo engqongileyo.Xa kuthelekiswa ne-oyile inkungu yokuthambisa, inani leoli kwi-oyile-moya yokuthambisa incinci kwaye izinzile, i-torque ye-friction incinci, kwaye ukunyuka kobushushu kuphantsi.Ilungele ngokukodwa iibheringi zesantya esiphezulu.
