Iyo camshaft ndeimwe yezvikamu zvakakosha zveinjini. Muviri mukuru wecamshaft isimbi yecylindrical ine hurefu hwakafanana neboka rehumburumbira. Kune akawanda makamera pairi kutyaira mavharuvhu. Nokudaro, basa guru re camshaft nderokudzora kuzarura nekuvhara kwevhavha.
Kushushikana kwekusangana pakati pekam ne tappet kwakakwira zvakanyanya, uye kukurumidza kutsvedza kwehama kwakakwirawo, saka kupfekedzwa kwekamera yekushanda kwakakomba. Mukupindura mamiriro ezvinhu aya, magazini yecamshaft uye cam work surface inofanira kuva nehupamhi hwepamusoro-soro, kushata kwepamusoro uye kusimba kwakakwana, pamwe chete nekupfeka kwepamusoro uye mafuta akanaka.
Common malfunctions
Kukundikana kwakajairika kwecamshafts kunosanganisira kupfeka zvisina kujairika, ruzha rusina kujairika, uye kuputsika. Zviratidzo zvekupfeka zvisina kujairika zvinowanzoitika kusati kwaitika ruzha uye kutsemuka.
(1) Iyo camshaft inenge iri pamagumo einjini yekuzora, saka mamiriro ekuzora haana tariro. Kana pombi yemafuta isina kukwana mafuta ekumanikidza nekuda kwekunyanya kushandisa nguva, nezvimwewo, kana nzira yemafuta yekuzora yakavharwa uye mafuta ekuzora haakwanise kusvika kune camshaft, kana torque yekusimbisa yebearing cap yekusimbisa mabhaudhi yakakurisa uye iyo yekuzora. mafuta haakwanise kupinda mugero recamshaft, zvinokonzeresa kusagadzika kwecamshaft.
(2) Kupfeka zvisina kujairika kwecamshaft kuchaita kuti gaka riri pakati pecamshaft nechigaro chekutakura riwedzere, uye camshaft ichaita axial displacement kana ichifamba, zvichikonzera ruzha rusina kujairika. Kupfeka zvisina kujairika kunokonzeresa kuti mukaha pakati pe drive cam uye iyo hydraulic tappet iwedzere. Kana iyo cam inosanganiswa neiyo hydraulic tappet, kukanganisa kuchaitika, izvo zvinokonzeresa ruzha rusina kujairika.
(3) Iyo camshaft dzimwe nguva ine kutadza kwakakomba sekutsemuka. Izvo zvinowanzokonzera hydraulic tappet kupaza kana kupfeka kwakanyanya, kushata kwakashata, kushata kwekamshaft mhando, uye camshaft timing gear kuputika.
(4) Mune zvimwe zviitiko, kukanganisa kwekamshaft kunokonzerwa nezvikonzero zvakaitwa nevanhu, kunyanya kana camshaft isina kunyatsoparadzaniswa uye yakaunganidzwa kana injini ichigadziriswa. Semuenzaniso, kana uchibvisa camshaft inotakura cap, shandisa sando kana screwdriver kupfakanya, kana pakuisa iyo inotakura cap, iyo inotakura cap haienderane nechigaro chekutakura, kana torque yekusimbisa yebhaudhi yekusimbisa. chivharo chekubereka chakakurisa. Paunenge uchiisa chivharo chinotakura, teerera kune inotungamira museve uye chinzvimbo nhamba pamusoro pechivharo chinotakura, uye shandisa torque wrench kuomesa bhaudhi yekuvhara yekusunga mabhaudhi zvinoenderana neyakatsanangurwa torque.
