Umonakalo kwangethuba kwiibheringi zokutyibilika uxhaphake kakhulu kunokuthwala ukudinwa, ngoko ke kubalulekile ukunqanda umonakalo kwangethuba kwiibheringi zokutyibilika.Ukugcinwa okuchanekileyo kweebheringi zokutyibilika kuyindlela esebenzayo yokunciphisa umonakalo wangaphambili kwiibheringi kunye nesiqinisekiso esithembekileyo sokwandisa ubomi bokuzala.Ngoko ke, ekugcinweni kwemihla ngemihla kunye nokulungiswa kwe-injini, ingqalelo kufuneka ihlawulwe kwimbonakalo kunye nokuma kwendawo ye-alloy, umva, isiphelo kunye neekona ze-bearing.Amanyathelo okuphucula iimeko zokusebenza zokuthwala, kwaye ubeke ingqalelo ekuthinteleni ukonakala kwangaphambili kwi-sliding bear.

① Ukulinganisa ngokungqongqo ukubumbana kunye nokungqukuva komngxuma ophambili wokuqulatha umzimba we-injini ye-diesel.Kumlinganiselo wokubambisana komngxuma ophambili we-injini yomzimba we-injini, i-coaxiality ye-injini ye-diesel kufuneka ilinganiswe ichaneke ngakumbi, kwaye ukuphuma kwe-crankshaft kulinganiswa ngaxeshanye, ukuze kukhethwe ubukhulu. yetyholo lokuzala ukwenza i-gap ye-oyile yokuthambisa ihambelane kwindawo nganye ye-axis.Apho i-injini ye-diesel iphantsi kweethayile eziqengqelekayo, iimoto ezibhabhayo, njl. njl., umanyano lwe-coaxiality yomngxuma oyintloko wokuthwala umzimba kufuneka uvavanywe phambi kokuba udityaniswe.Kukho neemfuneko zokujikeleza kunye ne-cylindricity.Ukuba idlula umda, akuvumelekanga.Ukuba ingaphakathi komda, sebenzisa indlela yokugaya (oko kukuthi, sebenzisa umlinganiselo ofanelekileyo womgubo obomvu okhokelayo kwi-bearing pad, uyibeke kwi-crankshaft kwaye uyijikelezise, ​​emva koko ususe isigqubuthelo sokuthwala ukujonga i-bearing pad. iindawo zikhutshiwe, utshintsho kubukhulu bulinganiswa ukuqinisekisa ukuthembeka kokusetyenziswa.

② Ukuphucula ukugcinwa kunye nomgangatho wokuhlanganisana kweebheringi, kwaye ulawule ngokungqongqo izinga lokudlula lokudibanisa iintonga.Ukuphucula umgangatho we-hinge yokuthwala, qinisekisa ukuba umva we-bearings ugudile kwaye awunamabala, kwaye iindawo zokumisa zihamba kakuhle;inani lokuzibhokoxa li-0.5-1.5mm, elinokuqinisekisa ukuba isihlahla esithwalayo sifakwe ngokuqinileyo kunye nomngxuma wesihlalo sokuthwala nge-elasticity yayo emva kwendibano;entsha 1. Zonke iintonga zokudibanisa ezidala zifunekayo ukulinganisa ukuhambelana kwazo kunye ne-twist, kunye neentonga zokudibanisa ezingafanelekanga azivumelekanga ukuba zingene emotweni;Isiphelo ngasinye seenhlahla eziphezulu kunye nezisezantsi ezifakwe kwisihlalo sokuthwala kufuneka zibe yi-30-50mm ephezulu kunendiza yesihlalo esiphetheyo, ngaphezu kwexabiso elinokuqinisekisa ukuba ukuthwala kunye nesihlalo sokuthwala kuhambelana ngokuqinileyo emva kokuqinisa iibholiti ze-cap. ngokwetorque ekhankanyiweyo, ukuvelisa amandla okwaneleyo okuzitshixa, ukuthwala akuyi kukhululeka, isiphumo sokutshabalalisa ubushushu silungile, kwaye ukuthwala kuthintelwe ekukhutshweni nasekunxibeni;indawo yokusebenza yebheringi ayinakulungelelaniswa ngokukrazula i-75% ukuya kwi-85% yamanqaku oqhagamshelwano kufuneka isetyenziswe njengomgangatho wokulinganisa, kunye nokucoca okufanelekileyo phakathi kwebheringi kunye nejenali kufuneka kuhlangabezane neemfuno ngaphandle kokukrazula.Ukongeza, nikela ingqalelo ukujonga umgangatho wokusetyenzwa kweejenali ze-crankshaft kunye neebheringi ngexesha lokuhlanganisana, kwaye uzalisekise ngokungqongqo inkqubo yokulungisa imimiselo yokuthintela ukufakela okungafanelekanga ngenxa yeendlela zofakelo ezingafanelekanga kunye ne-torque engalinganiyo okanye engahambelaniyo yokuthwala iibholiti, okukhokelela ekuguqeni ukugoba kunye uxinzelelo Ukugxilwa kwengqondo, okukhokelela kumonakalo kwangaphambili ekuthwaleni.

Qhuba iitshekhi kwiindawo ezithengiweyo kumatyholo amatsha.Gxininisa ekulinganiseni ukuhlukana kobunzima besihlahla esithwala kunye nobukhulu bokuvulwa kwamahhala, kwaye uhlolisise umgangatho womphezulu ngokubonakala.Emva kokucoca kunye nokuvavanya iibheringi ezindala zikwimeko efanelekileyo, umzimba wokuqala, i-crankshaft yasekuqaleni, kunye neebheringi zangaphambili zihlanganiswe kwaye zisetyenziswe kwi-situ.

Qinisekisa ukucoceka kwendibano ye-injini ye-diesel kunye ne-oyile ye-injini.Ukuphucula ukusebenza kwezixhobo zokucoca, ukulawula ngokungqongqo umgangatho wokucoca, kunye nokuphucula ukucoceka kweendawo ezahlukeneyo zeenjini zedizili.Ngelo xesha, indawo yendibano yahlanjululwa kwaye i-cylinder liner cover cover yenziwa, ephucula kakhulu ukucoceka kwendibano ye-diesel injini.

③Khetha ngokufanelekileyo kwaye ugcwalise ioyile yokuthambisa.Ngethuba lokusetyenziswa, ioli yokuthambisa kunye noxinzelelo oluphantsi lwefilimu yeoli kufuneka ikhethwe ukunciphisa ifuthe lokuhamba kweoli xa iibhubhu zomoya ezibunjiweyo ziwa, ezinokuthintela ngokufanelekileyo ukuthwala i-cavitation;ibakala le-viscosity yeoli yokuthambisa akufanele linyuswe ngokuthanda, ukuze linganyusi umthamo wokuthwala.Ukuthambekela kokupheka kwe-injini;umphezulu we-oyile yokuthambisa we-injini kufuneka ube phakathi koluhlu olusemgangathweni, izixhobo ze-oyile yokuthambisa kunye ne-refueling kufuneka zicoceke ukuthintela nakuphi na ukungcola namanzi ukuba angangeni, kwaye kwangaxeshanye uqinisekise isiphumo sokutywinwa kwenxalenye nganye ye-injini.Nika ingqalelo ekuhlolweni rhoqo kunye nokutshintshwa kweoli yokuthambisa;indawo apho ioli yokuthambisa igcwaliswe kufuneka ingabikho kungcoliseko kunye nezivunguvungu zesanti ukuthintela ukungena kwazo zonke izinto ezingcolisayo;akuvumelekanga ukuxuba ioyile yokuthambisa yeempawu ezahlukeneyo, amabakala ahlukeneyo e-viscosity kunye neentlobo ezahlukeneyo zokusetyenziswa.Ixesha lemvula kufuneka lingabi ngaphantsi kwe 48h.

④ Sebenzisa kwaye ugcine injini ngokuchanekileyo.Xa ufaka i-bearing, i-shaft kunye nomgangatho ohambayo wokuthwala kufuneka ufakwe ngeoli ye-injini ecocekileyo yophawu oluchaziweyo.Emva kokuba iibheringi ze-injini zibuyiselwe, cima isitshixo sesibaso phambi kokuba uqalise okokuqala, sebenzisa isiqalisi ukuqhuba injini ukuba ingasebenzi amaxesha ambalwa, uze uvule kwaye uvule iswitshi yamafutha xa igeyiji yoxinzelelo lweoyile ibonisa. umboniso, kwaye ubeke i-throttle embindini kunye nendawo yesantya esisezantsi ukuqalisa injini.Qwalasela ukusebenza kwenjini.Ixesha le-idling alinakudlula kwimizuzu emi-5.Yenza umsebenzi olungileyo ekusebenzeni komatshini omtsha kunye ne-injini emva kokulungiswa ngokutsha.Ngethuba lokuhamba kwexesha, akuvumelekanga ukusebenza phantsi kweemeko zokunyuka ngokukhawuleza kunye nokuncipha komthwalo kunye nesantya esiphezulu ixesha elide;Inokuvalwa kuphela emva kwemizuzu eyi-15 yokusebenza kwesantya esiphantsi phantsi komthwalo, ngaphandle koko ubushushu bangaphakathi abuyi kuchithwa.

Lawula ngokungqongqo ubushushu bokuqala belocomotive kwaye unyuse ixesha lokubonelela ngeoyile lokuqalisa.Ebusika, ukongeza ekulawuleni ngokungqongqo amaqondo obushushu okuqala e-locomotive, ixesha lokubonelela nge-oyile kufuneka landiswe ukuqinisekisa ukuba i-oyile ifikelela kwiiperi ezingqubanayo ze-injini ye-diesel kwaye kuncitshiswe ukukhuhlana okuxubeneyo kwesibini ngasinye sokukhuhlana xa injini yedizili iqala. .Ukutshintshwa kwe-oyile yokucoca.Xa umahluko woxinzelelo phakathi kwangaphambili nasemva kwe-oyile yokucoca ufikelela kwi-0.8MPa, iya kutshintshwa.Ngexesha elifanayo, ukwenzela ukuba kuqinisekiswe umphumo wokucoca ioli, i-oyile yokucoca kufuneka itshintshwe rhoqo ukuze kuncitshiswe umxholo wokungcola kwioli.

Ukomeleza ukucocwa kunye nokugcinwa kwesihluzo se-oyile kunye nesixhobo sokungenisa umoya we-crankcase, kwaye ubeke indawo yokucoca ngexesha ngokwemiyalelo;qinisekisa ukusebenza okuqhelekileyo kwenkqubo yokupholisa injini, lawula ubushushu obuqhelekileyo be-injini, thintela iradiyetha ukuba “ibilise”, kwaye ukwalela ngokungqongqo ukuqhuba ngaphandle kokupholisa amanzi; Ukhetho oluchanekileyo lwepetroli, uhlengahlengiso oluchanekileyo lwesigaba sokusasazwa kwerhasi kunye nexesha lokutshisa, njl. ., ukuthintela ukutsha okungaqhelekanga kwe-injini: khangela ngexesha elifanelekileyo kwaye ulungelelanise ubume bezobugcisa be-crankshaft kunye neebheringi.

Rhoqo ukwenza uhlalutyo lwe-ferrographic ye-oyile ye-injini ukunciphisa iingozi.Idityaniswe nohlalutyo lwe-ferrographic ye-oyile ye-injini, ukunxiba okungaqhelekanga kunokubonwa kwangoko.Ngokwepateni yohlalutyo lwe-ferrographic ye-oyile ye-injini, ukwakheka kweenkozo ezirhabaxa kunye neendawo ezinokubakho zinokumiselwa ngokuchanekileyo, ukuze kuthintelwe iingxaki ngaphambi kokuba zenzeke kwaye kuthintelwe ukwenzeka kwengozi yokutsha kwethayile yeshafu.
