Izinga le-camshaft axial clearance lithi: injini kaphethiloli ngokuvamile ingu-0.05 ~ 0.20mm, hhayi ngaphezu kuka-0.25mm; Injini kadizili ngokuvamile 0 ~ 0.40mm, hhayi ngaphezu 0.50mm. Ukucaciswa kwe-axial ye-camshaft kuqinisekiswa ukubambisana phakathi kwe-thrust surface kanye nesihlalo esiphethe i-camshaft ekhanda le-cylinder. Lokhu kugunyazwa kuqinisekiswa ukubekezelelana kobukhulu bezingxenye futhi akukwazi ukulungiswa mathupha.

Ngemuva kokuthi iphephabhuku le-camshaft lisebenze isikhathi eside, igebe lizokhula ngenxa yokugqoka nokukhala, okuholela ekuhambeni kwe-axial ye-camshaft, engathinti kuphela ukusebenza okujwayelekile kwesitimela se-valve, kodwa futhi kuthinta ukusebenza okujwayelekile kwe-camshaft. izingxenye zokushayela.

Hlola ukucaciswa kwe-axial ye-camshaft. Ngemuva kokukhipha ezinye izingxenye zeqembu lokudlulisa ama-valve, sebenzisa i-dial gauge probe ukuze uthinte ekugcineni kwe-camshaft, uphushe futhi udonse i-camshaft ngaphambili nangemuva, bese ucindezela igeji yokudayela iqonde ekugcineni kwe-camshaft ukwenza i-camshaft Axial movement. , ukufundwa kwenkomba yokudayela kufanele kube mayelana ne-0.10mm, futhi umkhawulo wokusetshenziswa kwe-axial clearance ye-camshaft ngokuvamile 0.25mm.

Uma i-bearing clearance inkulu kakhulu, buyisela i-bearing. Hlola futhi ulungise i-axial clearance ye-camshaft ebekwe nge-bearing cap. I-camshaft yenjini ibekwe kahle endaweni yesihlanu ye-camshaft, futhi i-camshaft ibekwe kahle ngobubanzi besigqoko sokuthwala kanye nejenali.
