(1) Jonga kwaye ulungelelanise i-axial clearance
Xa ujonga i-axial clearance ye-injini esebenzisa i-thrust flange ye-axial positioning, faka igeyiji yokuziva phakathi kobuso besiphelo sejenali yokuqala ye-camshaft kunye ne-thrust flange okanye phakathi kobuso besiphelo se-hub yegiya yexesha kunye ne-thrust flange. Ubunzima be-gauge ye-feeler yi-axial clearance ye-camshaft. Ngokuqhelekileyo yi-0.10mm, kunye nomda ophezulu we-0.25mm. Ukuba ukukhutshwa akuhambelani neemfuno, kunokulungiswa ngokunyuka okanye ukunciphisa ubukhulu be-thrust flange.

(2)Ukuhlolwa kunye nokulungiswa kwe-deformation ye-camshaft yokugoba
Ukuguqulwa kokugoba kwecamshaft kulinganiswa ngempazamo yeradial runout yejenali ephakathi yecamshaft kwiijenali kuzo zombini iziphelo. Indlela yokuhlola iboniswe kumzobo. Beka i-camshaft kwintsimbi ye-V, kunye ne-V-shaped iron kunye nesalathisi sokudayela kwi-flat plate, ukwenzela ukuba uqhagamshelwano lwesalathisi sokudayela ludibene ngokuthe nkqo kunye nejenali ephakathi ye-camshaft. Jika i-camshaft kwaye ujonge umahluko we-swing yenaliti yesalathiso sokucofa, eyinqanaba lokugoba lecamshaft. Emva kokuba ukuhlolwa kugqityiwe, thelekisa iziphumo zokuhlola kunye nexabiso eliqhelekileyo lokugqiba ukuba ngaba ukulungiswa okanye ukubuyisela.

(3) Ezinye izinto zokulungisa icamshaft
1) Ukuhlolwa kwejenali yeshaft yegiya yexesha elingundoqo: Inqwelomoya yesitshixo yejenali yeshafti yegiya yexesha kufuneka ingqamane nenqwelomoya yolingano yokunyuswa okuphezulu kwesilinda sokuqala sokungena kunye neekham zokukhupha. Ukunxiba kwayo kuya kutshintsha ixesha levalvu. Ukuba isitshixo sinxibile, sinokuphinda sivulwe ngokufaka i-welding okanye sivulwe kwindawo entsha.
2) Eyona nto inxitywa kakhulu kwivili lokumpompa i-petroli i-eccentric wheel: Eyona nto inxitywayo ye-petroli pump drive eccentric wheel ngokubanzi yi-1mm. Ukuba idlula lo mda, i-camshaft kufuneka itshintshwe.

Ixabiso lokubaleka kobubanzi: umgangatho - 0.01 ~ 0.03 mm, umda - 0.05 ~ 0.10 mm.
3) Ukuhlolwa kunye nokulungiswa kokunxiba kwekhamera
Xa ixabiso eliphezulu lokunciphisa ukunyusa kwekhamera likhulu kune-0.40mm okanye i-cumulative wear of the cam surface idlula i-0.80mm, i-camshaft kufuneka itshintshwe; xa i-cumulative wear of the cam surface ingaphantsi kwe-0.80mm, ikhamera inokugatywa kwi-grinder ye-camshaft.
Nangona kunjalo, iikhamera zee-camshafts ze-injini yemoto yanamhlanje zizinto zonke ezidityanisiweyo zomgca. Ngenxa yokuchaneka okuphezulu kakhulu kokusebenza kunye neendleko eziphezulu zokulungisa, azifane zilungiswe okwangoku, kwaye i-camshaft iyatshintshwa ngokubanzi.

4) Ukuhlolwa kunye nokugcinwa kweejenali ze-camshaft kunye neebheringi
① Ukuhlolwa kwejenali yecamshaft kunye nokuzala: Sebenzisa i-micrometer ukulinganisa impazamo yokujikeleza kunye nempazamo ye-cylindricality yejenali yecamshaft. Impazamo yokujikeleza kwejenali ye-camshaft ayiyi kuba nkulu kuno-0.015mm, kwaye impazamo ye-coaxiality yejenali nganye ayiyi kudlula i-0.05mm. Ngaphandle koko, kufuneka ilungiswe ngokomlawuli.
② Ukuhlolwa kwe-camshaft bearing: Xa ukukhutshwa okuhambelanayo kwe-camshaft ye-bearing kudlula umda wokusetyenziswa, i-bearing entsha kufuneka itshintshwe.
