7. Ukuvuza kweoyile yeCrankshaft

Oomatshini abatsha bahlala benezizathu ezilandelayo:

1. Indawo yokuvula i-piston ring ayidityaniswanga ngokweemfuno, ukuvuza kwe-piston ring kubi kakhulu, i-cylindricity ye-cylinder liner iphumile, umgodi oyintloko we-shaft kunye ne-cylinder liner hole perpendicularity iphumile kwi-whack kunye nepiston. Ukuvuleka kweringi kuya kwicala elinye ngenxa yezizathu ezahlukeneyo, ezi zinto zibangela ukuba ixabiso elibi loxinzelelo lwekhrankcase lehle, kwaye ibangela ukuba ukuvuza kweoli ye-crankshaft yeoli. Isisombululo kukutshintsha iindawo ezingafanelekanga ngokwezona ngxaki kwaye zihlanganiselwe ngokweemfuno.

2. I-Crankshaft 50_8.os mm uburhabaxa bejenali bukhulu, inokupholishwa i-crankshaft ukuze isonjululwe.

3. I-Crankshaft oil seal assembly skew, ngeli xesha kufuneka iphinde idityaniswe nesitywina seoyile,

Ukuthambisa; Ngamanye amaxesha indibano ye-oyile yokutywinwa ingaphakathi kakhulu, kwaye ukuvuza kweoyile ye-oyile ye-crankshaft kuya kubangwa kukuvalela inxenye yomngxuma wokubuyiswa kwe-oyile yesigqubuthelo se-oyile engundoqo. Ke ngoko, xa udityaniswa, isitywina seoyile ye-crankshaft kufuneka sibekwe kwindawo esekupheleni kwesigqubuthelo sokusonta nge-1.5 ~ 2 mm.

4 Umgangatho we-oyile ye-crankshaft umbi, umlebe awugudi, awuthambeki, kufuneka utshintshwe ngesitywina se-oyile esisemgangathweni. Ukuba i-oil seal spring ilahlekile okanye imodeli ayilunganga, intwasahlobo kufuneka itshintshwe ngexesha okanye i-oyile entsha yophawu olufanayo kufuneka itshintshwe.

5. Xa udibanisa isitywina se-oyile, umlebe wesitywina se-oyile ukrwela ngomphambili wesitshixo sesitshixo se-flywheel kwi-crankshaft, nto leyo eya kubangela ukuvuza kwe-oyile. Ke ngoko, xa ufaka isitywina se-oyile, ungaqala ujike indlela yesitshixo ye-crankshaft flywheel ukuya kwindawo ephezulu, ukrwele umda wangaphambili wendlela yesitshixo ngencakuba yesarha endala, kwaye uphakamise itywina le-oyile ngesandla xa isitywina seoyile yecrankshaft. ibekwe ngaphakathi, ukuze kuthintelwe ukukrwela umlebe we-oil seal.

6. Ngaphambi kokudibanisa isitywina se-oyile, i-crank shaft efana ne-50-8.o. Ioyile kwijenali ye-mm inokubangela ukuvuza kweoyile ye-crankshaft. Ke ngoko, phambi kokudibanisa i-oyile ye-crankshaft, kufuneka siqinisekise ukuba ingqekembe ye-crankshaft eyi-50-8.os mm ijenali icocekile kwaye ayinaoyile.
