Iyini indima yegiya le-camshaft
Umsebenzi oyinhloko wegiya le-camshaft ukulawula isenzo sokuvula nokuvala se-valve ukuze uqinisekise ukusebenza okujwayelekile kwenjini. I-Camshaft Gears, ngokusebenzisa ukwakheka kwawo okukhethekile, okufana ne-cam ye-cam enomumo weqanda, yenza kahle izinqubo zokudla kanye nokuqeda umthelela wokuvula nokuvala, ukuqiniseka ngokuvulwa kwe-valve nokugqoka, ukusebenza kahle kwenjini.
Amagiya e-Camshaft afuna kakhulu ukuklama nokwakha futhi ajwayele ukwenziwa ngensimbi ephezulu ye-alloy ukuqinisekisa amandla nokusekelwa kwawo. I-Camshaft ifakwa ngaphansi komthelela we-periodic
Ngaphezu kwalokho, igiya le-camshaft libuye libhekele ukuqinisekisa ukuvumelanisa okunembile phakathi kwe-crankshaft kanye ne-camshaft, futhi amandla we-crankshaft adluliselwa kwi-camshaft ngebhande lamazinyo wesikhathi, futhi i-oda elijwayelekile elisebenzayo lenjini liyagcinwa. Le ndlela yokuxhumana eqondile iqinisekisa ukuhamba okubushelelezi kwe-piston yangaphakathi yenjini, ukuvula okufika ngesikhathi nokuvalwa kwe-valve nokulandelana okunembile kokungathathi, ukuze injini ihlala isesimweni esihle kakhulu sokusebenza okuhlelekile.
I-Camshaft Gear iyingxenye ebalulekile yenjini, umsebenzi wayo oyinhloko ukuqinisekisa ukuguquguquka okuvumelanayo phakathi kwe-crankshaft ne-camshaft, ukuze kulawule isikhathi sokuvula nokuvala se-valve yenjini. Igiya le-camshaft lixhumeke kwigiya le-crankshaft ngebhande lezinyo lesikhathi noma eqoqweni lesikhathi ukuze uqinisekise ukuthi i-valve ivuliwe futhi ivaliwe ngesikhathi esifanele, ngaleyo ndlela ivaliwe ngokusebenza okujwayelekile kwenjini.
Ukwakheka kanye nomgomo wokusebenza
Igiya le-camshaft livame ukuxhumeka kwigiya le-crankshaft ngebhande lezinyo lesikhathi noma i-time chain. Lokhu kuxhumana kuqinisekisa ukuthi i-valve ivula lapho i-piston ifinyelela esikhungweni esiphezulu esiphezulu futhi ivala lapho i-piston yehla, ngaleyo ndlela ilawule izinqubo zokudla kanye nezinqubo zokuphelelwa umoya. Lokhu kuguqulwa okuvumelanayo okuqondile kuqinisekisa ukusebenza okubushelelezi nokusebenza kahle kwenjini.
Inqubo yokusebenza neyokukhiqiza
Ukukhetha kwe-Camshaft Gear Material kunethonya elibalulekile ekusebenzeni kwalo. Izinto ezijwayelekile zifaka i-cast iron, insimbi esontayo kanye nensimbi. I-Cast Iron ilungele izinjini eziningi ezijwayelekile ngenxa yentengo yayo ephansi kanye nokuphikiswa okuhle nokuqina kokuqina. I-Cast Steel ilungele izinjini zamandla aphezulu ngenxa yamandla ayo aphezulu namandla okuthwala umthwalo. Ukukhokhiswa kwensimbi kufanelekile ukusebenza okuphezulu nezinjini zejubane eliphakeme ngenxa yamandla abo aphezulu kanye nokugqoka.
Ukulungiswa nokuhlolwa
Ngokulungiswa kwansuku zonke, kubaluleke kakhulu ukubheka ubuqotho bebhande lezinyo lesikhathi kanye nesimo sesondo lokungezwani. Kuyadingeka ukuqinisekisa ukuthi ukuqondiswa kokujikeleza kwebhande le-Timing Tear kumakwe ngokucacile ukugwema ukudideka ngesikhathi sokuhlukaniswa. Ngaphezu kwalokho, ukuhlolwa okujwayelekile kokugqokwa kwebhande le-Timing Gear, isimo sesondo lengxabano kanye nokuqondanisa kwamamaki ukuqinisekisa ukunemba kokufakwa kuyisinyathelo esiyisihluthulelo sokuqinisekisa ukusebenza kwenjini.
