Nje ukuba ukuqengqeleka kwe-injini ye-crankshaft kusilele, kuyakuchaphazela ngqo ubume bobugcisa be-injini. Ngoko ke, ingqalelo kufuneka ihlawulwe ekungaphumeleli kwe-rolling bearing. Ukusilela okuqhelekileyo kwe-rolling bearing ngoku kuhlalutywa ngolu hlobo lulandelayo: 1. Kukho umsantsa phakathi kokunyakaza kwamakhonkco angaphakathi nangaphandle okuthwala kunye nokunxitywa kweendawo zokukhwelana.

①. Iringi yangaphandle yokuthwala ijikeleza. Ukuze kuququzelelwe ukuchithwa kunye nokudibanisa, i-ring yangaphandle ye-rolling bearing ithatha ukulungelelaniswa kwenguqu kunye nomngxuma wokuhlala. Ukuphazamiseka okuphezulu kwendandatho yangaphandle ye-front bear yi-0.035mm, kunye nokukhutshwa okuphezulu ngu-0.013mm. Ukuphazamiseka okuphezulu kwendandatho yangaphandle yebhere ngasemva yi-0.016mm, kunye nokukhutshwa okuphezulu ngu-0.06mm. Xa udibanisa, umgodi wokuhlala kufuneka ulinganiswe, kwaye ukuphazamiseka kwayo okanye ukucocwa akufanele kudlule uluhlu olungentla, ngaphandle koko umgodi wokuhlala kufuneka ulungiswe.

②. Iringi yangaphakathi yokuthwala ijikeleza. I-ring yangaphakathi ye-rolling bearing ithatha ukungenelela okuhambelana nejenali. Ukuphazamiseka okuphezulu kwe-diameter yangaphakathi ye-front bear yi-0.055mm, kunye nokuphazamiseka okuncinci ngu-0.012mm. Ukuphazamiseka okuphezulu kobubanzi bangaphakathi bebhere ngasemva yi-0.046mm, kunye nokuphazamiseka okuncinci ngu-0.003mm. Ukususela kumbono wolungelelaniso ongentla, ukuba ukuthwala kuye kwachithwa kwaye kwahlanganiswa ngamaxesha amaninzi, kunokubakho umsantsa phakathi kweringi yangaphakathi yebheringi kunye nejenali, ijenali kufuneka ilungiswe ngaphambi kokuba isetyenziswe.

Xa ukulingana phakathi kwebheringi kunye ne-shaft kukhululekile, abanye abasebenzi bolondolozo basebenzisa i-embossing okanye ukubethelela umphezulu we-shaft ekhululekileyo ukugubha umphezulu we-shaft kwiinzame zokufumana umphezulu oqinileyo. Oku akukona nje ukutshabalalisa i-geometric shape ye-shaft surface, yenza ukuba i-bearing ingafumani indawo echanekileyo yeziko ngexesha lofakelo kunye ne-skews, kodwa kunye nenxalenye edibeneyo iya kugqitywa kwaye ibe yinto ekhululekile. Indlela yokulungisa echanekileyo kukusila nokulungisa ijenali kuqala, uze emva koko ubrashe okanye utshize ijenali.

2. I-rolling bear cage igugile, ikhubazekile okanye yaphukile

①. Xa udibanisa amakhonkco angaphakathi nangaphandle kwi-rolling bearing, ngenxa yokuphazamiseka okukhulu, iibhola ezithwala zinamathele kwindandatho yokuhlala, kwaye i-cage yokuthwala igxininiswe ngokulula ngexesha lokusebenza. Ngoko ke, ukulinganisa kufuneka kwenziwe ngexesha lokudibanisa ukuqinisekisa ukuphazamiseka okusemgangathweni.

②. Ukuthambisa kwebheringi ye-crankshaft luhlobo lwe-splash. Xa ukuthwala kunqongophala okanye kungenayo ioli yokuthambisa, ngakumbi xa umthwalo osebenza kwi-bearing umkhulu, ubushushu obuthweleyo bukhuphuka. Ngokuqhelekileyo, ubushushu bendandatho yangaphakathi yokuthwala bumalunga ne-10 ° C ngaphezu kwendandatho yangaphandle. Ngenxa yokuba ukwanda kwe-thermal yamakhonkco angaphakathi nangaphandle kuyahluka, isithuba phakathi kwebhola kunye ne-raceway siyanyamalala, kwaye i-cage inokuthi ifake xa i-bearing iqhuba. Ngoko ke, xa ufaka i-bearing, i-oyile ecocekileyo yokuthambisa kufuneka isetyenziswe kwi-raceway ukukhusela i-oyile yokuthambisa ukuba ingatshizi kwaye ibangele ukukhuhlana okomileyo.

3. Umdyarho oqengqelekayo kunye nokuqengqeleka komphezulu wokuxobula

①. Ukucoca okubangelwa ngumthwalo wempembelelo kunye noxinzelelo olutshintshanayo. Izinto eziqengqelekayo zokuthwala kunye nemidyarho yangaphakathi nangaphandle yeringi zonke ziphantsi kwemithwalo ye-cyclic pulsating, ekhokelela ekutshintsheni koxinzelelo lonxibelelwano. Xa inani lemijikelezo yoxinzelelo lifikelela kwixabiso elithile, ukudinwa kwe-spalling kwenzeka kwiindawo zokusebenza zezinto ezijikelezayo okanye i-raceways yangaphakathi nangaphandle. Ukuba umthwalo wokuthwala ukhulu kakhulu, oku kukhathala kuya kwanda. Ukongezelela, ukuba ukuthwala kufakwe ngokungalunganga kwaye i-shaft igobile, i-raceway inokukhupha. I-flywheel kunye ne-pulley ye-injini ixhotyiswe nge-counterweights, kwaye umzuzu ojikelezayo we-inertia oveliswayo ulungelelaniswa nomzuzu ojikelezayo we-inertia oveliswa yinxalenye ejikelezayo ye-injini. Ukuba umzuzu owenziweyo we-inertia awulungelelaniswanga, i-injini iya kungcangcazela kakhulu emva komlilo, nto leyo eya kwandisa inani loxinzelelo olutshintshanayo kunye nemijikelo yoxinzelelo, ebangela ukuba umzila womdyarho kunye nokuqengqeleka komphezulu we-elementi ukuba uxobule phambi kwexesha.

Ukuze kuthintelwe ukugqobhoza kumphezulu wendlela yomdyarho kunye nezinto eziqengqelekayo, umthwalo owongezelelweyo kunye nokungcangcazela okungafanelekanga kufuneka kuphetshwe ngexesha lokusetyenziswa, ukuthontsiza kunye nesantya kufuneka zisetyenziswe ngokufanelekileyo ngexesha lokusebenza ukuthintela ukungqubeka kwetrektara, kwaye iibholiti zomzimba ezisisigxina kufuneka zigcinwe. ihlolwe rhoqo ukuthintela ukukhulula .

②. Ngenxa yokuba amaqhekeza angaphandle anzima awela kwindawo ehambelanayo yegobolondo okanye phakathi kwendawo ehambelanayo ye-shaft kunye nendandatho, imilo yendlela yomdyarho igqwethiwe. Into eqengqelekayo ibeka olona xinzelelo lukhulu apha, okukhokelela ekugugeni okukhawulezileyo kunye nokuxobuka kwesinyithi kwindlela yomdyarho weringi. I-Rolling bearing yinxalenye echanekileyo kakhulu, enovakalelo kakhulu kwimiba yangaphandle. Kwinkqubo yokulondoloza, sebenzisa ilaphu elicocekileyo, elingenalo i-wiper. Ilaphu wiper kufuneka kuthatyathelwe indawo umsonto umqhaphu endala, kuba umsonto uphela kwilaphu umqhaphu endala zixutywe lula kwi oyile yokuthambisa kwaye ungene ukuthwala, nto leyo eyingozi kakhulu. Phambi kokudibanisa, coca ngokucokisekileyo ijenali, umngxuma wesitulo, kunye nomphezulu weringi yangaphakathi nangaphandle yebheringi ukuthintela ubumdaka ukuba bungene kwindawo yokukhwelana.

③. Umonakalo obangelwe kumonakalo wendlela yomdyarho ngexesha lofakelo. Ukuba ngexesha lofakelo, uxinzelelo olusetyenzisiweyo luhanjiswa ngendandatho yangaphandle kunye nebhola yensimbi, ngokuqinisekileyo iya kubangela imingxuma kwindawo apho i-raceway yendandatho idibanisa nebhola yensimbi. Ibhere yaxobuka kwaye yachithwa ngexesha elifutshane. Ngoko ke, izixhobo ezikhethekileyo kufuneka zisetyenziswe xa kuchithwa, kwaye iindawo ezithwala amandla kufuneka zichaneke kwaye zilingane.

4. Ukukhutshwa kwe-radial kunye ne-axial yokunyusa ukunyuka

Ukukhutshwa kwe-radial kunye ne-axial yeebheringi zanda, ngaphandle kokutshatyalaliswa okomileyo kunye nokugqithisa okugqithisileyo kunye nokugqoka ngexesha lokuqalisa. Ikakhulu ibangelwa ukungqubuzana phakathi kweentsimbi zetsimbi kumphezulu wamacandelo kunye nesanti, uthuli kunye nokungcola kwioli yokuthambisa kwizinto ezijikelezayo kunye ne-raceways.

Ukuthwala kunokwanda okuphawulekayo kwi-clearance phakathi kwendandatho kunye nezinto ezijikelezayo ngenxa yokugqoka i-abrasive, i-matte surface yenziwe kwindlela yokugijima, kwaye kubonakala iimpawu zomkrwelo ezingalinganiyo. Indlela yokuthintela kukutshintsha ioli yokuthambisa kwangethuba, yaye umngxuma wokuthambisa kufuneka ungangeni moya ukuze uthintele ukungena kokungcola.
