Yintoni indima ye-camshaft gear
Umsebenzi ophambili we-camshaft gear kukulawula ukuvulwa kunye nokuvala isenzo sevalve ukuqinisekisa ukusebenza okuqhelekileyo kwe-injini. Iigiya zecamshaft, ngoyilo lwazo olukhethekileyo lwemilo, njengecala leCAM elimile okweqanda, kwandisa inkqubo yokungena kunye nokukhupha isilinda, ngelixa unciphisa impembelelo kunye nokunxiba ngexesha lokuvulwa nokuvalwa kwevalvu, ukuqinisekisa ukuqina kunye nokusebenza kakuhle kwe-injini.
Iigiya zeCamshaft zifuna kakhulu ukuyila kunye nokwenza kwaye zihlala zenziwe ngentsimbi ekumgangatho ophezulu wealloy ukuqinisekisa amandla kunye nenkxaso yazo. I-Camshaft iphantsi komthwalo wempembelelo yexesha elithile kwinkqubo yokusebenza, uxinzelelo loqhagamshelwano phakathi kwe-CAM kunye ne-tappet lukhulu kwaye isantya sokutyibilika esihambelanayo sikhawuleza, ngoko indawo yokusebenza ye-CAM kufuneka ibe nobukhulu obuchanekileyo obuchanekileyo, ubunzima obuphantsi, ukuqina okwaneleyo, okulungileyo. ukunxiba ukumelana kunye nefuthe lokuthambisa.
Ukongeza, i-camshaft gear ikwanoxanduva lokuqinisekisa ulungelelwaniso oluchanekileyo phakathi kwe-crankshaft kunye ne-camshaft, kwaye amandla e-crankshaft adluliselwa kwi-camshaft ngebhanti lezinyo lexesha, kunye nomyalelo oqhelekileyo wokusebenza we-injini. Le ndlela yokudibanisa ichanekileyo iqinisekisa ukuhamba kakuhle kwepiston yangaphakathi ye-injini, ukuvulwa kwangethuba kunye nokuvalwa kwevalve kunye nolandelelwano oluchanekileyo lokutshisa, ukuze injini ihlale ikwimo esebenza kakuhle yokulungelelaniswa.
Isixhobo se-camshaft yinxalenye ephambili ye-injini, umsebenzi wayo ophambili kukuqinisekisa ukujikeleza okuhambelanayo phakathi kwe-crankshaft kunye ne-camshaft, ukuze kulawulwe ixesha lokuvula kunye nokuvala i-valve ye-injini. Isixhobo se-camshaft siqhagamshelwe kwigiya ye-crankshaft ngokusebenzisa ibhanti lezinyo lexesha okanye ikhonkco lexesha ukuqinisekisa ukuba ivalve ivuliwe kwaye ivalwe ngexesha elifanelekileyo, ngaloo ndlela igcina inkqubo eqhelekileyo yokusebenza kwe-injini.
Ubume kunye nomgaqo wokusebenza
Isixhobo se-camshaft sihlala sidityaniswa kwigiya ye-crankshaft ngebhanti lezinyo lexesha okanye ikhonkco lexesha. Olu nxibelelwano luqinisekisa ukuba ivalve ivula xa ipiston ifikelela kwiziko eliphezulu lokufa kwaye ivale xa ipiston ihla, ngaloo ndlela ilawula inkqubo yokungena kunye nokukhupha. Oku kujikeleziswa kwe-synchronous ngokuchanekileyo kuqinisekisa ukusebenza kakuhle kunye nokusebenza kakuhle kwe-injini.
Izinto eziphathekayo kunye nenkqubo yokuvelisa
Ukukhethwa kwezinto eziphathekayo ze-camshaft kunempembelelo ebalulekileyo ekusebenzeni kwayo. Izinto eziqhelekileyo zibandakanya isinyithi esityhidiweyo, isinyithi esityhidiweyo kunye neentsimbi zentsimbi. Intsimbi yentsimbi ifanelekile kwiinjini ezininzi eziqhelekileyo ngenxa yexabiso layo eliphantsi kunye nokumelana nokunxiba kakuhle kunye nokuzinza kwe-thermal. Intsimbi yokuphosa ifanelekile kwiinjini eziphezulu zamandla ngenxa yamandla ayo aphezulu kunye nomthamo wokuthwala umthwalo. Ii-forging zentsimbi zilungele ukusebenza okuphezulu kunye neenjini zesantya esiphezulu ngenxa yamandla azo aphezulu kunye nokunganyangeki.
Ukugcinwa kunye nokuhlolwa
Ekugcinweni kwemihla ngemihla, kubaluleke kakhulu ukujonga ingqibelelo yebhanti lezinyo lexesha kunye nemeko yevili loxinzelelo. Kuyimfuneko ukuba kuqinisekiswe ukuba ulwalathiso olujikelezayo lwebhanti yegiya lexesha luphawulwe ngokucacileyo ukuphepha ukudideka ngexesha lokuchithwa. Ukongezelela, ukuhlolwa rhoqo kokunxiba kwebhanti lexesha, imeko yevili loxinzelelo kunye nokulungelelaniswa kwamanqaku ukuqinisekisa ukuchaneka kofakelo linyathelo eliphambili lokuqinisekisa ukusebenza kwe-injini.
