I-camshaft ingenye yezingxenye ezibalulekile zenjini. Umzimba oyinhloko we-camshaft iyinduku ye-cylindrical cishe ngobude obufana neqembu le-cylinder. Kukhona amakhamera amaningana kuwo ukushayela ama-valve. Ngakho-ke, umsebenzi oyinhloko we-camshaft ukulawula ukuvulwa nokuvalwa kwe-valve.
Ingcindezi yokuxhumana phakathi kwekhamera ne-tappet iphezulu kakhulu, futhi isivinini sokuslayida esihlobene siphezulu kakhulu, ngakho-ke ukugqokwa kwendawo yokusebenza yekhamera kubucayi kakhulu. Ekuphenduleni lesi simo, ijenali ye-camshaft kanye nendawo yokusebenza yekhamera kufanele ibe nokunemba okuphezulu kobukhulu, ubuhwaba obuncane obungaphezulu nokuqina okwanele, kanye nokumelana nokugqokwa okuphezulu kanye nokugcotshwa okuhle.

Ukungasebenzi kahle okuvamile

Ukwehluleka okuvamile kwama-camshaft kuhlanganisa ukuguga okungavamile, umsindo ongavamile, nokuphuka. Izimpawu zokuguga okungavamile zivame ukwenzeka ngaphambi komsindo ongajwayelekile nokuphuka.
(1) I-camshaft isicishe ibe sekupheleni kwesistimu yokuthambisa yenjini, ngakho-ke isimo sokugcotshwa asinaso ithemba. Uma iphampu kawoyela inengcindezi eyanele yokuhlinzeka uwoyela ngenxa yesikhathi sokusetshenziswa ngokweqile, njll., noma indawo kawoyela wokugcoba ivinjiwe futhi uwoyela wokugcoba awukwazi ukufinyelela ku-camshaft, noma i-torque eqinisayo ye-bearing cap fastening bolts inkulu kakhulu futhi okokugcoba. uwoyela awukwazi ukungena kwigebe le-camshaft, lizobangela ukuguga okungavamile kwe-camshaft.
(2) Ukuguga okungavamile kwe-camshaft kuzodala igebe phakathi kwe-camshaft nesihlalo esithwalayo ukuba likhule, futhi i-camshaft izoba ne-axial displacement lapho ihamba, okuholela kumsindo ongavamile. Ukuguga okungavamile kuzobangela futhi igebe phakathi kwekhamera yokushayela kanye ne-tappet ye-hydraulic. Uma ikhamera ihlanganiswa ne-tappet ye-hydraulic, kuzoba nomthelela, okuzodala umsindo ongavamile.
(3) I-camshaft ngezinye izikhathi inokwehluleka okukhulu njengokuphuka. Izimbangela ezivamile ukuqhekeka kwe-tappet ye-hydraulic noma ukuguga okukhulu, ukugcotshwa okubi kakhulu, ikhwalithi ephansi ye-camshaft, kanye nokugqashuka kwegiya lesikhathi le-camshaft.
(4) Kwezinye izimo, ukwehluleka kwe-camshaft kubangelwa izizathu ezenziwe umuntu, ikakhulukazi lapho i-camshaft ingahlakazwa kahle futhi ihlanganiswe lapho injini ilungiswa. Isibonelo, lapho ususa i-camshaft bearing cap, sebenzisa isando noma i-screwdriver ukuze ucindezele ingcindezi, noma lapho ufaka i-bearing cap, indawo ye-bearing cap ayihambisani nesihlalo sokuthwala, noma i-torque eqinisayo ye-bolt yokuqinisa. isivalo sokuthwala sikhulu kakhulu. Lapho ufaka isembozo esithwalayo, naka umcibisholo wesiqondiso kanye nenombolo yesikhundla ebusweni bekhava elithwalayo, futhi usebenzise isikrufu se-torque ukuze uqinise amabhawodi okubopha ikhava elithwalayo ngokuhambisana ngokuqinile netorque eshiwo.
