I-axial clearance ye-crankshaft ibizwa nangokuthi i-clean clearance ye-crankshaft. Ekusebenzeni kwenjini, uma igebe lincane kakhulu, izingxenye zizobambeka ngenxa yokwanda okushisayo; uma igebe likhulu kakhulu, i-crankshaft izobangela ukunyakaza kwe-axial, isheshise ukugqoka kwesilinda, futhi ithinte ukusebenza okuvamile kwesigaba se-valve kanye ne-clutch. Uma injini isilungisiwe, ubukhulu balesi sikhala kufanele bubhekwe futhi bulungiswe kuze kube bufaneleka.

Isilinganiso sokucaciswa kwe-crankshaft sihlanganisa ukukalwa kwe-axial clearance kanye nesilinganiso esiyinhloko se-bearing radial clearance.

(1) Ukukalwa kwe-axial clearance ye-crankshaft. Ugqinsi lwepuleti elithwala i-thrust ekugcineni elingemuva le-crankshaft linquma ukuphuma kwe-axial ye-crankshaft. Lapho ukala, beka inkomba yokudayela ngaphambili ekugcineni kwe-crankshaft yenjini, shaya i-crankshaft ukuyibuyisela emuva endaweni elinganiselwe, bese uqondanisa inkomba yokudayela ku-zero; bese uyisa i-crankshaft phambili endaweni yomkhawulo, bese inkomba yokudayela Inkomba ye-axial clearance ye-crankshaft. Kungabuye kukalwa nge-feeler gauge; sebenzisa izikrudrayiva ezimbili ukuze zifake ngokulandelana kwazo phakathi kwekhava ethile eyinhloko kanye nengalo ehambisanayo ye-crankshaft, futhi ngemva kokunqamula i-crankshaft phambili noma emuva endaweni yomkhawulo, faka i-feel gauge ku-bearing yesikhombisa. , leli gebe yigebe le-axial le-crankshaft. Ngokwemithetho yokuqala yemboni, izinga le-axial clearance ye-crankshaft yale moto ingu-0.105-0.308mm, kanti umkhawulo wokugqoka ngu-0.38mm.

(2) Isilinganiso se-radial clearance of main bear. Ukucaciswa phakathi kwejenali eyinhloko ye-crankshaft kanye ne-aying eyinhloko i-radial clearance. Lapho ukala, faka igeji yentambo yepulasitiki (igeji yegebe lepulasitiki) phakathi kwejenali eyinhloko kanye ne-biring enkulu, futhi qaphela ukuthi ungaphendukisi i-crankshaft ukuvimbela igebe ekushintsheni ngesikhathi sokuzungezisa futhi ulume igeji yegeji. Kufanele kuqashelwe ithonya lekhwalithi ye-crankshaft ekukhishweni.
