Mekhoa ea tlhokomelo ea Crankshaft le litlhoko tsa li-cranes tsa boenjiniere: ho phalla ha radial ea crankshaft le radial runout ea sefahleho sa thrust holim'a axis e tloaelehileng ea makasine e kholo e tlameha ho finyella litlhoko tsa tekheniki. Ho seng joalo, e tlameha ho lokisoa. Lekola litlhoko tsa boima ba likoranta tsa crankshaft le likoranta tse hokahanyang, tse tlamehang ho fihlela litlhoko tsa tekheniki. Ho seng joalo, e lokela ho nchafatsoa ho fihlela litlhoko tsa tšebeliso. Haeba bolt ea boima ba crankshaft e robehile, e tlameha ho nkeloa sebaka. Ka mor'a hore crankshaft e nkele sebaka sa "balance block" kapa "balance block bolt", ke nako ea ho etsa tlhahlobo e matla ea ho leka-lekana ho kopano ea crankshaft ho netefatsa hore chelete e sa leka-lekaneng e finyella litlhoko tsa tekheniki. Electrode e thibelang ho roala.

(1) Harola le ho hloekisa likarolo tsa crankshaft ho etsa bonnete ba hore karolo ea ka hare ea oli ea crankshaft e hloekile ebile e sa thijoa.

(2) Etsa ho lemoha liphoso ho crankshaft. Haeba ho na le petso, e tlameha ho nkeloa sebaka. Sheba ka hloko koranta e kholo ea crankshaft, koranta ea rod e hokahanyang le arc ea eona ea phetoho, 'me libaka tsohle li tlameha ho se be le mengoapo, ho chesoa le makukuno.

(3) Sheba koranta e kholo ea crankshaft le koranta ea rod e hokelang, 'me u li lokise ho latela boemo ba tokiso ka mor'a hore boholo bo fete moeli. Tokiso ea koranta ea crankshaft e tjena:

(4) Lekola litlhoko tsa boima ba likoranta tsa crankshaft le likoranta tse hokahanyang, 'me li tlameha ho fihlela litlhoko tsa tekheniki. Ho seng joalo, e lokela ho nchafatsoa ho fihlela litlhoko tsa tšebeliso.

(5) Maqhubu a radial a crankshaft le radial runout ea sefahleho sa ho sututsa ho axis e tloaelehileng ea jenale e kholo li tlameha ho fihlela litlhoko tsa tekheniki. Ho seng joalo, e tlameha ho lokisoa.

(6) Ho ts'oana ha molamu oa koranta ea khokahanyo ho axis e tloaelehileng ea koranta e kholo e tlameha ho fihlela litlhoko tsa tekheniki.

(7) Ha likere tse ka pele le tse ka morao tsa crankshaft li petsohile, li senyehile kapa li tsofetse haholo, crankshaft e lokela ho nkeloa sebaka.

(8) Haeba bolt ea boima ba crankshaft e robehile, e tlameha ho nkeloa sebaka. Ka mor'a hore crankshaft e nke sebaka sa boima ba 'mele kapa bolt ea boima ba' mele, ke nako ea ho etsa tlhahlobo e matla ea ho leka-lekanya ho kopano ea crankshaft ho netefatsa hore chelete e sa leka-lekaneng e finyella litlhoko tsa tekheniki. Electrode e thibelang ho roala

(10) Lekola ka hloko mohanyetsi oa leoto la crankcase. Haeba e senyehile, rabara e tsofala, e phatlohile, e holofetse kapa e phatlohile, e tlameha ho nkeloa sebaka.

(11) Ha u kopanya crankshaft, ela hloko ho kenngoa ha li-bearings tse ka sehloohong le li-thrust bear. Lekola sebaka sa "crankshaft axial clearance" 'me u tiise liboutu tse otlolohileng le liboutu tse tšekaletseng kamoo ho hlokahalang.
