Umgangatho we-camshaft axial clearance ngulo: injini yepetroli ngokuqhelekileyo i-0.05 ~ 0.20mm, ingabi ngaphezu kwe-0.25mm; Injini yedizili idla ngokuba yi-0 ~ 0.40mm, hayi ngaphezulu kwe-0.50mm. Ukukhutshwa kwe-axial ye-camshaft kuqinisekiswe yintsebenziswano phakathi kwe-thrust surface kunye ne-camshaft ephethe isihlalo kwintloko ye-cylinder. Le mvume iqinisekisiwe ngokunyamezelwa kwe-dimensional yamacandelo kwaye ayikwazi ukulungiswa ngesandla.

Emva kokuba ijenali ye-camshaft isebenze ixesha elide, i-gap iya kwanda ngenxa yokugqoka kunye nokukrazula, okubangelwa ukuhamba kwe-axial ye-camshaft, engachaphazeli nje ukusebenza okuqhelekileyo kwesitimela se-valve, kodwa ichaphazela nokusebenza okuqhelekileyo kwe-camshaft. iindawo zokuqhuba.

Jonga i-axial clearance yecamshaft. Emva kokususa ezinye iinxalenye zeqela lokuhambisa ivalve, sebenzisa i-dial gauge probe ukuze uchukumise isiphelo se-camshaft, utyhale kwaye utsale i-camshaft ngaphambili nangasemva, kwaye ucinezele i-dial gauge ngokuthe nkqo ekupheleni kwe-camshaft ukwenza i-camshaft Axial movement. , ukufundwa kwesalathisi sokudayela kufuneka kube malunga ne-0.10mm, kwaye umda wokusetyenziswa kwe-axial clearance ye-camshaft ngokuqhelekileyo. 0.25mm.

Ukuba i-bearing clearance inkulu kakhulu, buyisela indawo yokuthwala. Jonga kwaye ulungelelanise i-axial clearance ye-camshaft ebekwe kunye ne-bearing cap. I-injini ye-camshaft ibekwe kwi-axially kwi-bearing camshaft yesihlanu, kwaye i-camshaft ibekwe nge-axially kunye nobubanzi be-cap kunye nejenali.
