Yenziwe ngezinto ezinjani i-crankshaft bearing yemoto?
I-crankshaft bearing yemoto (ekwaziwa ngokuba yi-crankshaft bearing okanye i-large bearing) sisingxobo se-sliding bearing esinesakhiwo esidibeneyo. Iquka ikakhulu umqolo wentsimbi kunye nomaleko we-alloy onciphisa ukuguguleka. Esi sakhiwo sidibanisa amandla kunye nokumelana nokuguguleka ukuze sivumelane nendawo yokusebenza yenjini enesantya esiphezulu, uxinzelelo oluphezulu, kunye nobushushu obuphezulu.
Ulwakhiwo oluphambili lwezinto ezibonakalayo
I-Steel back: Yenziwe ngentsimbi ekhabhoni ephantsi okanye i-alloy steel, enika inkxaso yesakhiwo kunye nokuqina.
I-alloy yokunciphisa ukuguguleka: Xa idibana ngqo ne-crankshaft, isebenza imisebenzi yokunciphisa ukungqubana, umthwalo wokuthwala, kunye nokuphelisa ubushushu. Iindidi eziqhelekileyo ziquka:
I-alloy yeBabbitt (esekwe kwitin okanye esekwe kwi-lead)
Iimpawu: Ukumelana nokuguguleka kakuhle kunye nokuzivumelanisa nezimo kakuhle
Ukusetyenziswa: Isetyenziswa kakhulu kwiinjini zepetroli ezinamazinga aphantsi okuqinisa
I-alloy esekwe kubhedu (efana ne-bronze ye-lead, i-alloy ye-copper-lead)
Iimpawu: Amandla aphezulu, ukumelana nokuguguleka okuphezulu, kunye nokumelana nobushushu obuphezulu
Isicelo: Ifanelekile kwiinjini zedizili okanye iinjini zepetroli ezinomthwalo omninzi
I-alloy esekwe kwi-aluminium (esekwe kwi-aluminium enesilivere ephezulu okanye ephantsi)
Iimpawu: Ubunzima obuncinci, ukusasaza ubushushu kakuhle, kunye nokumelana nokuguguleka okugqwesileyo
Ukusetyenziswa: Okwangoku yeyona isetyenziswa kakhulu kwiibheringi ze-crankshaft zenjini yokutsha yangaphakathi. Ingcaciso eyongezelelweyo
Ii-alloys ezisekelwe kwi-aluminium ziye zaba lukhetho oluphambili ngenxa yokusebenza kwazo okugqwesileyo, ngakumbi ezifanelekileyo kwiinjini zanamhlanje ezinesantya esiphezulu sokujikeleza kunye nokusebenza okuqhubekayo.
Ezinye iimveliso ezikumgangatho ophezulu ziya kunyangwa njengokufakelwa kwetin kunye ne-phosphating kumphezulu we-alloy onganyangekiyo ukuze kuphuculwe ngakumbi iipropati zokungqubana.
Iijenali ze-crankshaft zihlala zisetyenziswa ngababini (phezulu nasezantsi), zifakwe phakathi kwejenali ephambili ye-crankshaft kunye nebhloko yesilinda, zixhomekeke kwifilimu yeoyile emalunga ne-0.005 millimeters ukuze kufezekiswe ukuthambisa okumanzi kunye nokuthintela ukudibana ngqo kwesinyithi.
Ukuze ubone izinto ezithile kwiijenali ze-crankshaft zesithuthi esithile, ungajonga incwadi yemiyalelo yokulungisa okanye ubuze ulwazi oluhambelanayo nge-Autohome Crankshaft Journal.
Iijenali ze-crankshaft zeemoto zizinto ezibalulekileyo ezithwala ii-sliding kwinjini. Imisebenzi yazo ephambili ingashwankathelwa ngolu hlobo lulandelayo:
Xhasa kwaye ulungise i-crankshaft: Qinisekisa ukuba i-crankshaft igcina indawo yayo ye-radial izinzile ngexesha lokujikeleza ngesantya esiphezulu, uphephe ukushukuma okanye ukuphambuka.
Yenza ifilimu yeoyile yokuthambisa ngolwelo: Misela ifilimu yeoyile encinci kakhulu (malunga ne-0.005 millimeters) phakathi kwejenali ye-crankshaft kunye nejenali, uguqula ukungqubana kwesinyithi ngqo kube kukuthambisa ngolwelo, nto leyo enciphisa kakhulu ukuguguleka.
Nciphisa ukungqubana kunye nokuguga: Ngokusebenzisa isakhiwo sesleeve esenziwe ngezinto ezinganyangekiyo ezifana ne-babbitt alloy kunye ne-copper-lead alloy, kunciphisa ngempumelelo ukungqubana kunye nokwandisa ubomi benjini.
Ukusasazwa kobushushu nokupholisa: Sebenzisa ukujikeleza kweoyile yenjini ukususa ubushushu obusebenzayo, ukuthintela iibheringi ukuba zingaphumeleli ngenxa yobushushu obuphezulu.
Indawo ye-Axial (kwezinye iintlobo): Iijenali ze-flanged crankshaft zinokunciphisa intshukumo ye-axial ye-crankshaft ecaleni kwe-axis, ukuqinisekisa indawo echanekileyo yeendawo ezihambayo.
Ukuba ukuthambisa akusebenzi kakuhle, indibano ayilunganga, okanye ioyile yenjini inezinto ezingcolileyo, inokubangela ukuba ifilimu yeoyile iqhekeke, nto leyo ekhokelela kwiimpazamo ezinkulu ezifana nokutshisa ijenali, ukubamba umngxuma, njl.njl., ezibonakala njengokuncipha koxinzelelo lweoyile, ingxolo engaqhelekanga, kunye nokuncipha kwamandla. Ke ngoko, ukutshintsha rhoqo ioyile yenjini kunye nezihluzi, kunye nokugcina imoto ngokweemfuno, kubaluleke kakhulu ekukhuseleni iibheringi ze-crankshaft.
Ukungaphumeleli kwe-crankshaft bearing emotweni (eyaziwa ngokuba "kukuphela kwe-bearing" okanye "ukuphuka kwe-bearing") yenye yezona ngxaki zinkulu zoomatshini kwinjini. Oku kubangelwa kukungaphumeleli kwe-lubrication, okubangela ukugaywa okomileyo, ukutsha kobushushu obuphezulu, kunye nokubanjwa phakathi kwe-crankshaft journal kunye ne-bearing. Kwiimeko ezinzima, kunokukhokelela ekutshatyalalisweni kwenjini.
Iimpawu eziphambili:
Ingxolo engaqhelekanga: Injini ikhupha isandi esirhabaxa esithi "tang, tang" okanye "buzzing" sentsimbi esirhabaxa, ngakumbi xa ikhawuleza.
Isilumkiso soxinzelelo lweoyile: Isibane sesalathisi soxinzelelo lweoyile kwideshibhodi siyakhanya, kwaye igeyiji yoxinzelelo lweoyile ibonisa ukufundwa okuphantsi.
Ukulahleka kwamandla: Amandla okukhupha injini ayancipha, kwaye isantya siba buthathaka.
Umsi ophuma kakhulu: Umsi omnyama unokukhutshwa.
I-alamu yobushushu obuphezulu: Ubushushu obuphezulu ngokungaqhelekanga bamanzi okanye ubushushu beoyile.
Ayikwazi ukuqala okanye injini ima: Kwiimeko ezigqithisileyo, i-crankshaft kunye ne-bearing ziyatsha kwaye zinamathele kunye, nto leyo ethintela injini ekujikelezeni.
Izizathu eziqhelekileyo:
Iingxaki zenkqubo yokuthambisa:
Uxinzelelo lweoyile olunganelanga (ukuguga kwepompo yeoyile, ukungasebenzi kakuhle kwevalvu yokunciphisa uxinzelelo, ukuvuza kwesekethe yeoyile).
Ubungakanani beoyile obungonelanga okanye obuwohlokileyo (ukungabikho kweoyile entsha ixesha elide, ukusetyenziswa kweoyile engeyoyaneleyo).
Ukuxuba ioyile (i-coolant engena kwipani yeoyile, njengokungasebenzi kweringi evimba amanzi ye-cylinder liner).
Iindlela zeoyile ezivaliweyo (ukungcola, iidiphozithi zekhabhoni, iziqwenga zesinyithi ezivala indlela ephambili yeoyile okanye imingxunya yeoyile ye-crankshaft).
Iingxaki zokuhlanganisa nokususa izinto:
Ukususwa kweebhereyitha okugqithisileyo okanye okunganelanga (okuchaphazela ukwakheka kwefilimu yeoyile).
Ukukhetha okanye ukufaka iibheringi ngendlela engalunganga.
Iindlela zokusebenza kunye neendlela zokusebenzisa:
Ukuqalisa injini ngesantya esiphezulu kwaye phantsi komthwalo onzima emva nje kokuba iqalile ukubanda.
Ukuqhuba ngesantya esiphezulu ixesha elide kunye nomthwalo onzima.
Ukuyimisa injini ngoko nangoko emva kokuba ishushu, nto leyo ebangela ukuba ifilimu yeoyile yonakale.
Iziphene zoyilo okanye zokuvelisa:
Ukugqitywa komphezulu ophantsi kunye nomgangatho wezinto ezibonakalayo ze-crankshaft okanye i-bearing.
Ukujikeleza kwejenali ye-crankshaft engaqhelekanga, ukuguqulwa, njl.
Iingcebiso zonyango:
Misa imoto ngoko nangoko: Xa kuvela iimpawu ezirhanelekayo zokungasebenzi kakuhle kweebheringi (ezifana nengxolo engaqhelekanga, i-alamu yoxinzelelo lweoyile), yimise imoto ngoko nangoko kwaye ungaqhubeki nokuqhuba. Oku kwenzelwa ukuthintela umonakalo ongakumbi.
Ulondolozo lobuchwephesha:
Tshintsha i-crankshaft main bearing (i-large bearing) kunye ne-connecting rod bearing (i-small bearing).
Jonga ukuba ijenali ye-crankshaft ikrwelwe, i-oxidized, itsaliwe, okanye ayilunganga na; ukuba umonakalo mkhulu, kuyimfuneko "ukugawula i-shaft" okanye ukutshintsha i-crankshaft.
Coca indlela yeoyile, tshintsha ipompo yeoyile kunye nesihluzi, kwaye ulungise iindawo ezivuzayo kwinkqubo yokupholisa.
Vavanya ukuba ingasetyenziswa na ngakumbi:
Ukuba "kukusilela kweebheringi ezincinci", emva kokulungiswa kobuchwephesha bokugaywa nokutshintshwa kweebheringi ezintsha, zingasetyenziswa kwakhona.
Ukuba ijenali ye-crankshaft igugile kakhulu, i-crankshaft yonakele okanye yaphukile, ngoko ke kuyimfuneko ukutshintsha i-crankshaft. Akukhuthazwa ukuqhubeka nokusebenzisa inxalenye endala.
Amanyathelo okuthintela:
Jonga rhoqo kwaye utshintshe ioyile kunye nesihluzi esihlangabezana neemfuno.
Ngaphambi kokuba uqhube, qinisekisa ukuba inqanaba leoyile likwinqanaba eliqhelekileyo (isikali esiphakathi se-dipstick).
Kuphephe ukusebenza ngesantya esiphezulu okanye umthwalo onzima emva nje kokuba iqalile ukubanda.
Fudumeza injini kubushushu bamanzi obungaphezulu kwama-40°C ngaphambi kokuba iqalise ebusika.
Nika ingqalelo kwimeko yeoyile: Ukuba kukho i-emulsification (umbala omhlophe, igwebu elininzi), i-viscosity enciphileyo, okanye ivumba lepetroli, yilungise ngoko nangoko.
