(1) Onani ndikusintha chilolezo cha axial
Mukayang'ana kutulutsa kwa axial kwa injini yomwe imagwiritsa ntchito chowongolera cha axial positioning, ikani choyezera chomveka pakati pa kutsogolo kutsogolo kwa magazini yoyamba ya camshaft ndi thrust flange kapena pakati pa mapeto a giya la nthawi ndi chitsulo chowombera. Makulidwe a choyezera chomverera ndi axial chilolezo cha camshaft. Nthawi zambiri ndi 0.10mm, ndi malire pazipita 0.25mm. Ngati chilolezocho sichikukwaniritsa zofunikira, chikhoza kusinthidwa ndikuwonjezera kapena kuchepetsa makulidwe a thrust flange.

(2)Kuyang'ana ndi kukonza kwa camshaft kupinda deformation
Kupindika kopindika kwa camshaft kumayesedwa ndi cholakwika cha radial runout cha magazini yapakati ya camshaft kumamagazini kumapeto onse awiri. Njira yowunikira ikuwonetsedwa pachithunzichi. Ikani camshaft pa chitsulo chooneka ngati V, ndi chitsulo chooneka ngati V ndi chizindikiro choyimba pa mbale yathyathyathya, kotero kuti kukhudzana kwa chizindikiro choyimba kumalumikizana molunjika ndi magazini yapakati ya camshaft. Tembenukirani camshaft ndikuwona kusinthasintha kwa singano yoyimba, yomwe ndi digiri yopindika ya camshaft. Kuyendera kukamalizidwa, yerekezerani zotsatira zoyendera ndi mtengo wokhazikika kuti mudziwe ngati mungakonze kapena kusintha.

(3) Zinthu zina zokonza camshaft
1) Kuyang'ana kwa nyuzipepala ya shaft ya nthawi: Ndege yofananira ya giya ya giya ya nthawi iyenera kugwirizana ndi ndege yofananira yokwera kwambiri ya silinda yoyamba yolowera ndi makamera otulutsa. Kuvala kwake kudzasintha nthawi ya valve. Ngati njira yakiyi yavala, imatha kutsegulidwanso ndi kuwotcherera kwapamtunda kapena kutsegulidwa pamalo atsopano.
2) Kuvala kwakukulu kwa gudumu loyendetsa pampu yamafuta: Kuvala kokwanira kwa gudumu la pampu yamafuta nthawi zambiri kumakhala 1mm. Ngati idutsa malire awa, camshaft iyenera kusinthidwa.

Kuthamanga kwa m'mimba mwake: muyezo - 0.01 ~ 0.03 mm, malire - 0.05 ~ 0.10 mm.
3) Kuyang'ana ndi kukonza zobvala za cam
Ngati mtengo wochepetsera wokwera kwambiri wa cam uli wokulirapo kuposa 0.40mm kapena kuvala kowonjezera kwa cam pamwamba kupitilira 0.80mm, camshaft iyenera kusinthidwa; pamene kuphatikizika kwa cam cam pamwamba kumakhala kochepera 0.80mm, kamera imatha kugwedezeka pa chopukusira cha camshaft.
Komabe, ma camshafts amakono a injini zamagalimoto onse ndi mitundu yolumikizana. Chifukwa cha kukonzedwa kwapamwamba kwambiri komanso mtengo wokonza wokwera, sizimakonzedwanso pakadali pano, ndipo camshaft nthawi zambiri imasinthidwa.

4) Kuyang'anira ndi kukonza magazini a camshaft ndi ma bere
① Kuyang'anira magazini ya camshaft ndi kunyamula: Gwiritsani ntchito micrometer kuyeza cholakwika chozungulira komanso cholakwika cha cylindricity cha magazini ya camshaft. Cholakwika chozungulira cha magazini ya camshaft sichikhala chachikulu kuposa 0.015mm, ndipo cholakwika cha coaxiality cha magazini iliyonse sichidzapitilira 0.05mm. Apo ayi, iyenera kukonzedwa molingana ndi wolamulira.
② Kuyang'ana kwa camshaft yonyamula: Pamene chilolezo chofananira cha camshaft chonyamula chidutsa malire ogwiritsira ntchito, chotengera chatsopano chiyenera kusinthidwa.
