Icamshaft yenye yeendawo eziphambili ze-injini. Umzimba oyintloko we-camshaft yintonga ye-cylindrical malunga nobude obufanayo kunye neqela le-cylinder. Kukho iikhamera ezininzi kuyo zokuqhuba iivalve. Ngoko ke, umsebenzi oyintloko we-camshaft kukulawula ukuvulwa nokuvalwa kwevalve.
Uxinzelelo loqhagamshelwano phakathi kwekhamera kunye ne-tappet luphezulu kakhulu, kwaye isantya sokutyibilika esihambelanayo siphezulu kakhulu, ngoko ke ukunxiba kwendawo yokusebenza yekhamera kubi kakhulu. Ukuphendula kule meko, ijenali yecamshaft kunye nomphezulu wokusebenzela wecam kufuneka ube nokuchaneka okuphezulu komgangatho, uburhabaxa obuncinci bomgangatho kunye nokuqina okwaneleyo, kunye nokumelana nokunxiba okuphezulu kunye nokuthambisa okulungileyo.

Ukungasebenzi kakuhle

Ukusilela okuqhelekileyo kwee-camshafts kubandakanya ukunxiba okungaqhelekanga, ingxolo engaqhelekanga, kunye nokuqhekeka. Iimpawu zokunxiba ngendlela engaqhelekanga zihlala zisenzeka phambi kokuba kubekho ingxolo engaqhelekanga kunye nokwaphuka.
(1) Icamshaft iphantse yasekupheleni kwenkqubo yokuthambisa ye-injini, ngoko ke imeko yokuthambisa ayinathemba. Ukuba impompo yeoli inoxinzelelo olwaneleyo lokubonelela ngeoyile ngenxa yexesha lokusetyenziswa ngokugqithisileyo, njl. njl., okanye i-oyile yokuthambisa ivaliwe kwaye ioyile yokuthambisa ayinakufikelela kwi-camshaft, okanye i-torque yokuqinisa i-cap yokubopha iibholiti inkulu kakhulu kwaye i-lubricating. Ioyile ayinakungena kwi-gap yecamshaft, iya kubangela ukunxiba okungaqhelekanga kwecamshaft.
(2) Ukunxitywa okungaqhelekanga kwe-camshaft kuya kubangela ukuba umsantsa phakathi kwe-camshaft kunye nesihlalo sokuthwala unyuke, kwaye i-camshaft iya kungena kwi-axial displacement xa ihamba, okukhokelela kwingxolo engaqhelekanga. Ukunxitywa okungaqhelekanga kuya kubangela ukuba umsantsa phakathi kwekhamera ye-drive kunye ne-hydraulic tappet yande. Xa ikhamera idibene ne-tappet ye-hydraulic, impembelelo iya kwenzeka, eya kubangela ingxolo engaqhelekanga.
(3) I-camshaft ngamanye amaxesha ineentsilelo ezinzulu ezifana nokuphuka. Ezona zizathu zixhaphakileyo kukuqhekeka kwetappet yehydraulic okanye ukunxitywa okuqatha, ukuthambisa kakubi kakhulu, umgangatho ombi wecamshaft, kunye nokugqabhuka kwegiya yexesha le-camshaft.
(4) Kwezinye iimeko, ukungaphumeleli kwe-camshaft kubangelwa izizathu ezenziwe ngumntu, ngakumbi xa i-camshaft ingachithwanga kakuhle kwaye idityaniswe xa injini ilungiswa. Ngokomzekelo, xa ususa i-camshaft ephethe i-cap, sebenzisa ihamile okanye i-screwdriver ukuze ucinezele uxinzelelo, okanye xa ufaka i-cap ye-bearing cap, indawo ye-capshaft ye-bearing cap ayihambelani nesihlalo sokuthwala, okanye i-torque yokuqinisa i-bolt yokuqinisa. umnqwazi wokuthwala mkhulu kakhulu. Xa ufaka isigqubuthelo sokuthwala, nikela ingqalelo kwi-arrow yesalathiso kunye nenombolo yesikhundla kumphezulu wesigqubuthelo sokuthwala, kwaye usebenzise i-torque wrench ukuqinisa i-bolt yokubopha i-bolts ngokuhambelana ngokungqongqo kunye ne-torque echaziweyo.
