Hakanan ana kiran cirewar axial na crankshaft kuma ana kiran ƙarshen ƙyalli na crankshaft. A cikin aikin injin, idan tazarar ta yi ƙanƙanta, sassan za su makale saboda haɓakar thermal; idan rata ya yi girma sosai, crankshaft zai haifar da motsi na axial, hanzarta lalacewa na silinda, kuma ya shafi aikin al'ada na lokaci na bawul da kama. Lokacin da aka gyara injin, yakamata a duba girman wannan gibin a daidaita shi har sai ya dace.

Ma'auni na sharewar crankshaft ya haɗa da ma'aunin sharewar axial da babban ma'aunin share fage na radial.

(1) Ma'auni na axial clearance na crankshaft. Kaurin farantin abin turawa a ƙarshen ƙarshen crankshaft yana ƙayyade izinin axial na crankshaft. Lokacin da ake aunawa, sanya alamar bugun kira a ƙarshen gaban injin ƙwanƙwasa, ƙwanƙwasa ƙwanƙwasa don matsar da shi baya zuwa matsakaicin matsayi, sannan daidaita alamar bugun kiran zuwa sifili; sa'an nan kuma matsar da crankshaft gaba zuwa iyakar matsayi, sa'an nan mai nuna bugun kira Mai nuna alama shine izinin axial na crankshaft. Hakanan za'a iya auna shi tare da ma'aunin ji; yi amfani da screwdrivers guda biyu don sakawa tsakanin wani babban murfin maɗaukaki da kuma hannun madaidaicin crankshaft, kuma bayan zazzage crankshaft gaba ko baya zuwa matsakaicin matsayi, saka ma'aunin jin daɗi a cikin ma'auni na bakwai Wanda aka auna tsakanin farfajiyar turawa da saman crankshaft. , wannan rata shine ratar axial na crankshaft. Dangane da ka'idodin masana'anta na asali, ma'auni don izinin axial na crankshaft na wannan motar shine 0.105-0.308mm, kuma ƙarancin lalacewa shine 0.38mm.

(2) Ma'aunin cirewar radial na babban ɗaukar hoto. Ƙimar da ke tsakanin babban jarida na crankshaft da babban abin da ke ciki shine ƙaddamarwar radial. Lokacin da ake aunawa, saka ma'aunin waya na filastik (plastic gap gauge) tsakanin babban jarida da babban abin da ake buƙata, kuma a kula kada a jujjuya ƙugiya don hana tazar ta canza yayin juyawa da cizon ma'aunin tata. Ya kamata a kula da tasirin ingancin crankshaft akan sharewa.
