Aikin ƙafafun siginar crankshaft.
Babban aikin da ke cikin tayoyin siginar crankshaft shine tantance matsayi da kusurwar crankshaft daidai, da kuma saurin injin. Yawanci yana aiki tare da na'urori masu auna matsayi na camshaft don tabbatar da ingantaccen aikin injin da kuma inganta aiki. A taƙaice:
Ƙayyade matsayin crankshaft: Tayar siginar crankshaft, ta hanyar ƙira da matsayinta na musamman, tana ba na'urar firikwensin damar gano matsayin yanzu da kusurwar crankshaft daidai, wanda yake da mahimmanci don sarrafa lokacin kunna wuta da allurar mai.
Aiki da na'urar firikwensin matsayi na camshaft: Tayar siginar crankshaft tana aiki tare da na'urar firikwensin matsayi na camshaft don tantance ainihin lokacin kunna wuta. Wannan haɗin gwiwa yana tabbatar da cewa ana iya kunna injin a daidai lokacin don aiki mai santsi da inganci.
Yawanci ana amfani da ƙafafun siginar crankshaft mai ƙafa 60-2, akwai ɓangaren haƙori da ya ɓace, ta hanyar na'urar firikwensin bisa ga siffar haƙori da kuma siginar babban da ƙasa ta ɓangaren haƙorin da ya ɓace don yin hukunci kan matakin crankshaft na 1. Wannan ƙira tana bawa na'urar firikwensin damar yin hukunci daidai da matsayi da matakin crankshaft ta hanyar siffar haƙori da siginar babban da ƙasa ta haƙorin da ya ɓace, don haka cimma daidaitaccen iko na yanayin aikin injin. Tsarin musamman na ƙafafun siginar crankshaft, tare da sarrafa siginar crankshaft ta ECU ( na'urar sarrafa lantarki) , yana ɗaya daga cikin mahimman fasahohi don cimma ingantaccen aiki da kwanciyar hankali na injin.
Kula da saurin injin: Tayar siginar crankshaft kuma tana sa ido kan saurin injin kuma tana aika bayanai zuwa ECU (sashen sarrafa lantarki) don daidaita lokacin ƙonewa da lokacin allura, wanda yake da mahimmanci don inganta ingancin mai da rage hayaki.
A takaice dai, siginar siginar crankshaft wani muhimmin abu ne a cikin injunan zamani, wanda ke taimakawa tsarin sarrafa injin don inganta aiki da kuma tabbatar da aiki lafiya ta hanyar samar da ingantaccen bayani game da matsayi da saurin aiki.
Mene ne alamun gazawar faifan siginar crankshaft?
Idan faifan siginar crankshaft ya gaza, zai yi tasiri iri-iri kan yadda motar ke aiki yadda ya kamata, galibi kamar haka:
Da farko, alamar lahani tana haskakawa, wanda shine martanin kai tsaye na tsarin binciken kai na motar bayan gano matsalar. Na biyu, lokacin kunna motar, zaku iya gano cewa tsarin farawa ya fi tsayi fiye da yadda aka saba, saboda injin yana ƙoƙarin farawa akai-akai ta hanyar firikwensin matsayin camshaft, amma saboda laifin faifan siginar, tsarin farawa yana da cikas. A lokacin tuki, aikin jirgin ruwan na iya shafar kuma ba zai iya aiki yadda ya kamata ba. Bugu da ƙari, injin na iya bayyana girgiza mara tsari, har ma yana fitar da hayaki mai launin fari.
Babban aikin firikwensin matsayi na crankshaft shine sa ido kan saurin injin, kuma bisa ga wannan bayanin don tantance adadin allurar mai da kuma kusurwar ci gaba da kunna wuta. Wannan yana tabbatar da cewa an kunna injin kuma an kunna shi a lokacin da ya dace, don haka rage lalacewar motar. Duk da haka, idan akwai matsala da allon siginar crankshaft, wannan jerin ayyukan sa ido da daidaitawa na iya shafar, wanda ke haifar da rashin kwanciyar hankali na aikin injin.
Ana sanya na'urar firikwensin matsayi na crankshaft a cikin mai rarrabawa, wanda muhimmin bangare ne na gano matsayin TDC na piston, don haka wani lokacin ana kiransa da na'urar firikwensin TDC. Da zarar wannan na'urar firikwensin ta gaza, ya kamata a duba ta kuma a gyara ta nan take don hana lalacewar fadada da haifar da ƙarin lalacewa ga abin hawa.
Idan kana son ƙarin bayani, ci gaba da karanta sauran labaran da ke wannan shafin!
Don Allah a kira mu idan kuna buƙatar irin waɗannan kayayyaki.
