Ukuri kwumwimerere wahimbwe kamashaft kubice byimodoka nziza

Igikoresho cya camshaft nigikoresho cyo kugenzura kamera, kikaba ari valve yimfuruka, igizwe na moteri yumuriro wamashanyarazi na valve ya eccentric hemispherical valve. Imashini ifata imiterere ihuriweho, kandi amashanyarazi afite sisitemu ya servo.

Ihame: Hindura igihe cyo gufungura cyo gufata no gusohora ibintu ukurikije akazi ka moteri. Iyo moteri iri munsi yumutwaro mwinshi, imashini ya camshaft ikoreshwa mugutezimbere impande zose za valve ukurikije umuvuduko wa moteri, kugirango itange umwuka mwiza mwicyumba cyaka gishoboka, kugirango ugere kumuriro mwinshi no kuruhande, kugirango utange icyumba cyo gutwika uko bishoboka kwose Umwuka mwiza kugirango ugere ku mbaraga nini na torque.

Kamashaft ni igice cya moteri ya piston. Igikorwa cyayo nukugenzura gufungura no gufunga valve. Nubwo umuvuduko wa camshaft muri moteri enye ya stroke ari kimwe cya kabiri cyikibiriti (umuvuduko wa kamera muri moteri ya moteri ebyiri nimwe nki ya crankshaft), mubisanzwe umuvuduko wacyo uracyari mwinshi cyane kandi ukeneye kwikorera itara rinini. Kubwibyo, igishushanyo gifite ibisabwa byinshi kugirango imbaraga nimbaraga zishyirwe hejuru ya camshaft, kandi ibikoresho byayo muri rusange ni ibyuma byujuje ubuziranenge cyangwa ibyuma bivangwa. Kuberako amategeko yimikorere ya valve afitanye isano nimbaraga nibikorwa biranga moteri, igishushanyo cya camshaft kigira uruhare runini mugikorwa cyo gushushanya moteri.
Umubiri nyamukuru wa camshaft ni inkoni ya silindrike ifite uburebure bungana na banki ya silinderi. Amashanyarazi menshi arayashyiraho kugirango atware valve. Amashusho ashyigikirwa mumashusho afite umwobo unyuze mu kinyamakuru camshaft, bityo umubare wibinyamakuru bya camshaft nikintu cyingenzi kigira ingaruka kumyitozo ya camshaft. Niba gukomera kwa kamashaft bidahagije, guhindagurika kugoreka bizabaho mugihe cyo gukora, bigira ingaruka kumwanya wa valve.
Uruhande rwa kamera rufite amagi. Yashizweho kugirango yizere neza gufata no gusohora silinderi. Byongeye kandi, urebye kuramba no kugenda neza kwa moteri, valve ntishobora kugira ingaruka nyinshi bitewe nigikorwa cyo kwihuta no kwihuta mugikorwa cyo gufungura no gufunga, bitabaye ibyo bizatera kwambara cyane kwa valve, urusaku rwinshi cyangwa izindi zikomeye ingaruka. Kubwibyo, kamera ifitanye isano itaziguye nimbaraga, ibisohoka bya torque no gukora neza bya moteri.
Amakosa asanzwe ya camshaft arimo kwambara bidasanzwe, amajwi adasanzwe no kuvunika. Kwambara bidasanzwe bikunze kubaho mbere yijwi ridasanzwe no kuvunika.
. Niba igitutu cyo gutanga amavuta ya pompe yamavuta kidahagije kubera igihe kinini cyakazi, cyangwa amavuta yo gusiga ntashobora kugera kumashanyarazi kubera guhagarika inzira yamavuta, cyangwa amavuta yo kwisiga ntashobora kwinjira mumashanyarazi kubera gukomera kwinshi. ya bolts yo gufunga igifuniko cyo kwifata, kamera izaba yambaye bidasanzwe.
. Kwambara bidasanzwe bizongera kandi icyuho kiri hagati ya kamera yo gutwara na tappet ya hydraulic, kandi kamera izahura na tappet ya hydraulic, bivamo urusaku rudasanzwe.
(3) Amakosa akomeye nko kuvunika kamashaft rimwe na rimwe bibaho. Impamvu zikunze kugaragara ni hydraulic tappet gucikamo ibice cyangwa kwambara gukomeye, gusiga nabi nabi, kutagira kamera nziza hamwe no kuvunika ibikoresho bya camshaft.
. Kurugero, mugihe ukuyeho igifuniko cya kamashaft, uyikubite inyundo cyangwa uyisige hamwe na screwdriver, cyangwa ushyireho igifuniko cyikibanza mumwanya utari wo, bikavamo kudahuza hagati yigitambaro cyo kwicara hamwe nicyicaro gikuru, cyangwa urumuri rukomeye rwa ibifunga bifunga igifuniko ni binini cyane. Mugihe ushyiraho igifuniko, witondere umwambi werekeza, numero yumwanya hamwe nibindi bimenyetso hejuru yigitwikirizo, hanyuma ushimangire imigozi ifunga igifuniko cya feri hamwe nigitereko cyumuriro ukurikije umurongo wagenwe.
