Rolling bearing chinhu chakakosha chemuchina.Kunyangwe kuita kwemota kunogona kukwidzwa zvizere kunoenderana nekuti kutakura kwacho kwakanyatsogadzirwa here.Zvinogona kutaurwa kuti lubrication chinhu chinodiwa kuti uve nechokwadi chekushanda kwakajairika kwekubereka.Izvo zvakakosha pakuvandudza simba rekutakura uye kushandiswa kwekubereka.Upenyu hunoita basa rinokosha.Motor kuberekamhando dzinowanzozorwa girizi, asi dzakazorwawo nemafuta.1 Chinangwa chekuzora Chinangwa chekutakura lubrication ndechekugadzira firimu remafuta rakatetepa pakati penzvimbo inotenderedza kana inotsvedza nzvimbo kudzivirira yakanangana nesimbi.Lubrication inoderedza kupokana pakati pesimbi uye inononoka kupfeka kwavo;kuumbwa kwefirimu yemafuta kunowedzera nzvimbo yekubatana uye kunoderedza kushushikana kwekubatana;inovimbisa kuti rolling bearing inogona kushanda zvakajairwa kwenguva yakareba pasi pepamusoro-frequency kusangana nekushushikana uye kuwedzera hupenyu hwekuneta;inobvisa kupisa kunopisa uye kunoderedza Kupisa kwekushanda kwebasa rekutakura kunogona kudzivirira kupisa;inogona kudzivirira huruva, ngura uye ngura.Mafuta ekuzora akakodzera mabheji ekumhanya-mhanya uye anogona kumira imwe dhigirii yekupisa kwepamusoro, uye zvakare inobata basa mukudzikisa kubereka vibration uye ruzha.

Mafuta ekuzora akakamurwa kuita: 3.3 Splash lubrication Splash lubrication inzira yakajairwa yekuzora yekuumburudza mabhengi mumagiya akavharwa ekufambisa.Inoshandisa zvikamu zvinotenderera, semagiya uye zvinokanda oiri, kumwaya mafuta ekuzora.Muparadzire paberero kana kuyerera mugororo remafuta rakagara rakagadzirwa padhuze nemadziro ebhokisi kupinda mubereko rinotendereka kuti uise mafuta ekuzora, uye mafuta ekuzora akashandiswa anogona kuunganidzwa mubhokisi uye kudzokororwa kuti ashandiswezve.Nekuti kutenderedza mabhengi hakudi chero zvivakwa zvekubatsira kana splash lubrication ichishandiswa, anowanzo shandiswa mune yakapusa uye compact gear transmissions.Nekudaro, iwo mapoinzi matatu anotevera anofanirwa kutariswa kana uchishandisa splash lubrication: 1) Mafuta ekuzora haafanire kunge akanyanya kukwirira, zvikasadaro iyo churning mafuta inoshandiswa ichave yakakura, uye mafuta anodhindwa.Iyo orifice inodonhedza mafuta kune fani yekuzora kubereka.Huwandu hwemafuta hunoshandiswa pamudzi weorifice hunogona kugadziriswa.Kubatsira kweiyi nzira yekuzora ndeye: chimiro chiri nyore, chiri nyore kushandisa;iyo yakashata ndeye: iyo viscosity haisi nyore kuve yakakwira zvakanyanya, zvikasadaro kudonha kwemafuta hakuzove kwakatsetseka, izvo zvinokanganisa iyo lubrication maitiro.Naizvozvo, inowanzo shandiswa pakuzora mafuta ekutenderedza mabhengi ane low speed uye light load.

Oiri yekugezesa yekugeza inonziwo mafuta-immersion lubrication, inova kunyudza iyo inotakura chikamu mumafuta ekuzora, kuitira kuti chimwe nechimwe chinotenderedza chebeche chinogona kupinda mumafuta ekuzora kamwe panguva yekushanda, uye kuunza mafuta ekuzora kune dzimwe nzvimbo dzinoshanda dze. kubereka.Tichifunga nezvekurasikirwa kunotyisa uye kukwira kwekushisa, kuitira kuti udzikise kuchembera kwemafuta ekuzora, zvakaoma kushandisa mafuta ekugezesa lubrication mumabheji akakwira-speed.Iyo sediment mudziva, yakadai semarara abrasive, inounzwa muchikamu chinotakura, ichikonzera kusakara.2) Mafuta ekuzora mubhokisi anofanirwa kugara akachena, uye iyo magineti adsorber inogona kushandiswa mudziva remafuta kuti ibvise marara abrasive uye yekune dzimwe nyika munguva yekudzikisa kuitika kweabrasive kupfeka.3) Mukugadzira dhizaini, tangi yekuchengetedza oiri uye orifice inotungamira kune inotakura inogona kuiswa pamadziro etangi, kuitira kuti iyo inotakura igone kukwizwa mubhati remafuta kana kudonha mafuta, uye lubrication inogona kuzadzikiswa kudzivirira kusakwana. kugovera mafuta.Oil circulation lubrication Oil circulation lubrication inzira yekushingairira kukwiza kukunguruka kunobereka zvikamu.Inoshandisa pombi yemafuta kusveta mafuta ekuzora kunze kwetangi remafuta, kuisuma muchigaro chinotenderedza kuburikidza nepombi yemafuta negomba remafuta, yozodzosera mafuta kutangi remafuta kuburikidza nechiteshi chemafuta chechigaro chinotakura, wozoishandisa mushure mekutonhodza nekusefa.Naizvozvo, rudzi urwu rwekuzora rubrication runogona kunyatso kuburitsa kupisa kwekukwenya uku uchibvisa kupisa kwakawanda, saka yakakodzera kutakura zvitsigiso nemutoro wakakura uye kumhanya kwakanyanya.

Oil injection lubrication imhando yemafuta ekutenderera kwemafuta.Nekudaro, kuitira kubvumidza mafuta ekuzora kuti apinde zvizere mukati memukati mekufamba kwepamusoro-yekumhanya-mhanya, uye panguva imwechete kudzivirira yakawandisa tembiricha kukwira uye yakawandisa frictional kuramba nekuda kwekuwanda kutenderera kutenderera kwemafuta pasi pe-high-speed yekushanda mamiriro, the mafuta anoiswa muchigaro chekutakura.Iyo muromo inowedzerwa kuchiteshi, uye iyo mafuta ekupa kudzvanywa inowedzerwa, uye oiri inopfapfaidzwa pane inotakura nemuromo kuti iwane lubrication uye kutonhora kwekubereka.Naizvozvo, mafuta jekiseni lubrication inzira yakanaka yekuzora, inonyanya kushandiswa kumhanyisa-kumhanyisa mabheji, uye inogona kushandiswa muzviitiko apo dmn kukosha kweiyo rolling bearing yakakura kupfuura 2000000mm · r/min.Kudzvinyirirwa kwepombi yemafuta yekuzora jekiseni remafuta kunowanzoita 3 kusvika ku5 bar.Kuti ukunde uye kudzivirira iyo Coanda mhedzisiro pasi pekumhanya kwakanyanya, iyo yekumhanyisa jekiseni remafuta painobuda nozzle inofanirwa kusvika kupfuura 20% yekumhanya kwemutsara wekutenderera.

Oiri mhute lubrication imhando yehushoma huwandu hwekuzora, iyo inoshandisa shoma shoma yemafuta ekuzora kusangana nezvinodiwa zvekuzora zvemabheji ekutenderera.Oiri mhute lubrication ndeye kushandura mafuta ekuzora kuita mhute yeoiri muoiri mhute jenareta, uye kuzora iyo inotakura kuburikidza neoiri mhute.Sezvo mhute yeoiri inonyura kuita madonhwe emafuta pane inoshanda pamusoro peiyo inotenderedza bearing, kutaura zvazviri kutakura kuchiri kuchengetedza chimiro chemafuta matete ekuzora.Kana iyo linear velocity yechinhu chinotenderedza chebearing chakakwira zvakanyanya, mafuta mhute lubrication inowanzo shandiswa kudzivirira kuwedzera kwekukwesha kwemukati kwemafuta uye kuwedzera kwekushisa kwekushanda kweiyo inotenderedza bearing nekuda kwekuwanda kwemafuta mune mamwe. lubrication nzira.Kazhinji, iyo mhute yemafuta inomanikidza inenge 0.05-0.1bar.Nekudaro, mapoinzi maviri anotevera anofanirwa kutariswa kana uchishandisa iyi nzira yekuzora: 1) Iyo viscosity yemafuta kazhinji haifanirwe kunge yakakwira kupfuura 340mm2/s (40 ° C), nekuti iyo atomization mhedzisiro haigone kuwanikwa kana iyo viscosity. zvakanyanyisa.2) Iyo mhute yeoiri yakasanganiswa inogona kuparara pamwe nemhepo uye kusvibisa nharaunda.Kana zvichidikanwa, shandisa mafuta uye gasi separator kuunganidza mhute yemafuta, kana kushandisa mudziyo wekufema kubvisa gasi rekubuda.

Oil-air lubrication inotora piston-type quantitative distributor, iyo inotumira shoma shoma yemafuta kune yakamanikidzwa kuyerera kwemhepo mupombi nguva nenguva, ichigadzira kuenderera kwemafuta kuyerera pamadziro epombi uye kuchipa kune kutakura.Sezvo mafuta matsva ekuzora achiwanzopihwa mukati, mafuta haachembera.Mhepo yakamanikidzwa inoita kuti zviome kuti tsvina yekunze ipinde mukati mebearing.Kuwanda kwemafuta emafuta kunoderedza kusvibiswa kunharaunda yakapoteredza.Kuenzaniswa nemafuta ekuzora mhute, huwandu hweoiri mumafuta-mhepo lubrication ishoma uye yakagadzikana, torque yefriction idiki, uye tembiricha inokwira yakaderera.Inonyanya kukodzera kune yakakwirira-speed bearings.
