I-axial clearance ye-crankshaft ikwabizwa ngokuba kukucocwa kwesiphelo se-crankshaft. Kwi-injini yokusebenza, ukuba i-gap incinci kakhulu, iindawo ziya kubambelela ngenxa yokwandiswa kwe-thermal; ukuba i-gap inkulu kakhulu, i-crankshaft iya kubangela ukunyakaza kwe-axial, ukukhawuleza ukunxiba kwe-cylinder, kwaye kuthintele ukusebenza okuqhelekileyo kwesigaba se-valve kunye ne-clutch. Xa i-injini ihlaziywa, ubukhulu beli gap kufuneka buhlolwe kwaye bulungiswe de bufaneleke.

Umlinganiselo wococeko lwe-crankshaft lubandakanya umlinganiselo we-axial clearance kunye ne-main bearing ye-radial clearance measurement.

(1) Umlinganiselo we-axial clearance yecrankshaft. Ubukhulu bepleyiti ethwele ithrust kwisiphelo esingasemva secrankshaft simisela ukucocwa kweaxial yecrankshaft. Xa ulinganisa, beka isalathisi sokudayela kwisiphelo esingaphambili se-crankshaft ye-injini, betha i-crankshaft ukuyibuyisela ngasemva kwindawo elinganiselweyo, emva koko ulungelelanise isalathisi sokudayela ku-zero; emva koko yisa icrankshaft phambili kwindawo emiselweyo, emva koko isalathisi sokucofa Isalathisi se-axial clearance yecrankshaft. Isenokulinganiswa ngegeyiji yokuziva; sebenzisa i-screwdrivers ezibini ukufaka ngokulandelelanayo phakathi kwesigqubuthelo esiphambili sokuthwala kunye nengalo yecrankshaft ehambelanayo, kwaye emva kokukroba i-crankshaft phambili okanye ngasemva ukuya kwindawo emiselweyo, faka igeyiji yokuvakala kwibheringi yesixhenxe. , lo msantsa ngumsantsa we-axial we-crankshaft. Ngokwemigaqo yokuqala yefektri, umgangatho wokukhutshwa kwe-axial ye-crankshaft yale moto ngu-0.105-0.308mm, kwaye umda wokunxiba ngu-0.38mm.

(2) Umlinganiselo wokukhutshwa kwe-Radial clearance of main bear. Ukucocwa phakathi kwejenali ephambili yecrankshaft kunye neyona nto iphambili kukukhutshwa kweradial clearance. Xa ulinganisa, faka igeyiji yocingo lweplastiki (i-gap gap gauge yeplastiki) phakathi kwejenali engundoqo kunye ne-bearing engundoqo, kwaye uqaphele ukuba ungajikelezi i-crankshaft ukukhusela i-gap ekutshintsheni ngexesha lokujikeleza kunye nokuluma i-gap gauge. Ingqalelo kufuneka ihlawulwe kwimpembelelo yomgangatho we-crankshaft ekucoceni.
