The axial clearance ea crankshaft e boetse e bitsoa pheletso ea crankshaft. Ts'ebetsong ea enjene, haeba lekhalo le le lenyenyane haholo, likarolo li tla khomarela ka lebaka la ho atolosoa ha mocheso; haeba lekhalo le le leholo haholo, crankshaft e tla baka motsamao oa axial, e potlakise ho roala ha cylinder, 'me e ama ts'ebetso e tloaelehileng ea karolo ea valve le clutch. Ha enjene e fetoloa, boholo ba lekhalo lena bo lokela ho hlahlojoa le ho lokisoa ho fihlela bo loketse.

Tekanyo ea clearance ea crankshaft e kenyelletsa tekanyo ea axial clearance le tekanyo e kholo ea ho bea radial clearance.

(1) Tekanyo ea axial clearance ea crankshaft. Botenya ba "thrust bearing plate" karolong e ka morao ea crankshaft bo etsa qeto ea ho hlaka ha axial ea crankshaft. Ha o metha, beha lets'oao la ho daela karolong e ka pele ea crankshaft ea enjene, otla crankshaft ho e khutlisetsa morao sebakeng se lekanyelitsoeng, ebe u hokahanya sesupo sa ho daela ho zero; ebe u isa crankshaft pele sebakeng sa moeli, ebe letšoao la ho daela Letšoao la ke ho hlaka ha axial ea crankshaft. E ka boela ea lekanyetsoa ka sekala sa feeler; Sebelisa li-screwdriver tse peli ho kenya ka ho latellana pakeng tsa sekoaelo se itseng sa mantlha le letsoho le ts'oanang la crankshaft, 'me ka mor'a ho phunya crankshaft ho ea pele kapa morao sebakeng se lekanyelitsoeng, kenya mochine oa sensor ho bering ea bosupa. , lekhalo lena ke lekhalo la axial la crankshaft. Ho ea ka melao ea pele ea fektheri, tekanyetso ea "axial clearance" ea crankshaft ea koloi ena ke 0.105-0.308mm, 'me moeli oa ho roala ke 0.38mm.

(2) Tekanyo ea "radial clearance" ea "bearing" e kholo. Phallo lipakeng tsa koranta e kholo ea crankshaft le ntlha e kholo ke ho hlaka ha mahlaseli. Ha o metha, kenya sekala sa terata ea polasetiki (plastic gap gauge) lipakeng tsa koranta e kholo le bering e kholo, 'me u hlokomele hore u se ke ua potoloha crankshaft ho thibela lekhalo ho fetoha nakong ea ho potoloha le ho loma sekala sa lekhalo. Tlhokomelo e lokela ho lefshoa tšusumetsong ea boleng ba crankshaft sebakeng sa tumello.
