I-Genuine Original camshaft eyakhiweyo yamalungu emoto yecherry

I-camshaft adjuster yi-valve yokulawula i-cam deflection, eyi-valve yekona ye-stroke, ehlanganiswe ne-actuator yombane yekona kunye ne-eccentric hemispherical valve.I-actuator ithatha isakhiwo esidibeneyo, kwaye i-actuator yombane inenkqubo ye-servo eyakhelweyo.

Umgaqo: Guqula ixesha lokuvula i-valve yokungena kunye nokukhupha ngokweemfuno zokusebenza ze-injini.Xa i-injini iphantsi komthwalo ophezulu, isilungisi se-camshaft sisetyenziselwa ukwandisa i-valve overlap angle ngokwesantya se-injini, ukuze unikeze umoya omtsha kwigumbi lokutsha ngokusemandleni, ukuze kuphunyezwe amandla aphezulu kunye ne-angle edibeneyo. ukuze ubonelele ngegumbi lokutsha kangangoko kunokwenzeka Umoya omtsha ukuphumeza amandla aphezulu kunye netorque.

Icamshaft yinxalenye yenjini yepiston.Umsebenzi wayo kukulawula ukuvulwa nokuvalwa kweevalve.Nangona isantya se-camshaft kwi-injini ye-stroke sisiqingatha se-crankshaft (isantya se-camshaft kwi-injini ye-stroke ephindwe kabini siyafana neso crankshaft), ngokuqhelekileyo isantya sayo sisephezulu kakhulu kwaye kufuneka thwala itorque enkulu.Ngoko ke, idizayini ineemfuno eziphezulu zamandla kunye nenkxaso yobuso be-camshaft, kwaye izinto zayo ngokuqhelekileyo ziyinsimbi ephezulu ye-alloy okanye i-alloy steel.Ngenxa yokuba umthetho wokuhamba kwevalvu unxulumene namandla kunye neempawu zokusebenza ze-injini, uyilo lwecamshaft ludlala indima ebaluleke kakhulu kwinkqubo yoyilo lwenjini.
Umzimba oyintloko we-camshaft yintonga ye-cylindrical malunga nobude obufanayo nebhanki ye-cylinder.Iikhamera ezininzi zinemikhono kuyo ukuze ziqhube ivalve.I-camshaft ixhaswa kwi-camshaft ye-bearing hole ngokusebenzisa ijenali ye-camshaft, ngoko ke inani leejenali ze-camshaft yinto ebalulekileyo echaphazela ukuqina kwenkxaso ye-camshaft.Ukuba ukuqina kwe-camshaft akwanelanga, i-deformation yokugoba iya kwenzeka ngexesha lokusebenza, echaphazela ixesha le-valve.
Icala lenkam limile okweqanda.Yenzelwe ukuqinisekisa ukungena okwaneleyo kunye nokukhutshwa kwe-cylinder.Ukongeza, ngokuqwalasela ukuqina kunye nokusebenza kakuhle kwe-injini, ivalve ayinakuba nefuthe elibi kakhulu ngenxa yokukhawulezisa kunye nenkqubo yokunciphisa inyathelo lokuvula kunye nokuvala, kungenjalo kuya kubangela ukuguga okunzulu kwevalve, ingxolo eyandisiweyo okanye enye into enzulu. iziphumo.Ke ngoko, ikhamera inxulumene ngokuthe ngqo namandla, ukuphuma kwetorque kunye nokusebenza ngokugudileyo kwenjini.
Iimpazamo eziqhelekileyo zecamshaft ziquka ukunxiba okungaqhelekanga, isandi esingaqhelekanga kunye nokuphuka.Ukunxiba okungaqhelekanga kuhlala kwenzeka phambi kwesandi esingaqhelekanga kunye nokwaphuka.
(1) Icamshaft iphantse yasekupheleni kwenkqubo yokuthambisa i-injini, ngoko ke imeko yokuthambisa ayinathemba.Ukuba uxinzelelo lwe-oyile yepompo yeoli alunelanga ngenxa yexesha elide lenkonzo, okanye ioli yokuthambisa ayikwazi ukufikelela kwi-camshaft ngenxa yokuvalwa kwendlela yeoli yokuthambisa, okanye i-oyile yokuthambisa ayinakungena kwi-camshaft clearance ngenxa yokuqina okugqithisileyo. yeebholiti zokuqinisa i-cover cover, i-camshaft iya kunxiba ngokungaqhelekanga.
(2) Ukunxitywa okungaqhelekanga kwecamshaft kuya kwandisa isithuba phakathi kwecamshaft kunye nesitulo sokuthwala, kwaye i-camshaft iya kuhamba nge-axially, okukhokelela kwisandi esingaqhelekanga.Ukunxitywa okungaqhelekanga kuya kwandisa umsantsa phakathi kwekhamera yokuqhuba kunye netappet ye-hydraulic, kwaye ikhamera iya kungqubana netappet ye-hydraulic, ekhokelela kwingxolo engaqhelekanga.
(3) Iimpazamo ezinzulu ezifana ne-camshaft fracture ngamanye amaxesha zenzeka.Ezona zizathu zixhaphakileyo kukuqhekeka kwetappet yehydraulic okanye ukunxitywa okumandundu, ukuthambisa kakubi kakhulu, umgangatho ophantsi wecamshaft kunye nokwaphuka kwegiya yexesha lecamshaft.
(4) Kwezinye iimeko, ukungaphumeleli kwe-camshaft kubangelwa yimiba yabantu, ngakumbi xa i-camshaft ingachithwanga ngokuchanekileyo ngexesha lokugcinwa kwe-injini.Umzekelo, xa ususa isigqubuthelo esithwele icamshaft, sibethe ngehamile okanye usikrole ngesikrudrayiva, okanye ufakele isigqubuthelo kwindawo engalunganga, nto leyo ekhokelela ekungahambelaniyo phakathi kwesigqubuthelo esibambeleyo kunye nesitulo sokuthwala, okanye itorque yokuqina. iibholiti zokuziqinisa zekhava yokuthwala zikhulu kakhulu.Xa ufaka i-cover cover, nikela ingqalelo kwi-arrow ye-directional, inombolo yendawo kunye namanye amanqaku kumphezulu we-cover cover, kwaye uqinise iibholiti zokuqinisa i-bearing cover kunye ne-torque wrench ngokuhambelana ngokungqongqo kunye ne-torque echaziweyo.
