Iindawo ezigugileyo ze-crankshaft ikakhulu ziyijenali ephambili kunye namabhovu e-shaft adibanisayo. Utshintshiselwano lwentshukumo ebuyelayo yepiston ye-injini ye-stroke emine kunye nokujikeleza kwe-crankshaft kuya kubangela ukuba i-crankshaft ikhuhlwe kwii-angles ezahlukeneyo. Oku kungqubuzana kuye kwancitshiswa kwinqanaba eliphantsi phantsi kwesenzo seoli yokuthambisa.

Xa injini isebenza ngesantya esiphezulu kwaye iphantsi komthwalo onzima, ukushisa kwehlathi elithweleyo kwandisa kwaye ukwanda kwe-thermal kwenzeka. Ke ngoko, umsantsa othile kufuneka ushiywe phakathi kokuthwala kunye nokuthwala ukukhusela i-crankshaft. Umsantsa phakathi kweshafti netyholo awunakuqinisekisa ukuba injini ibaleka amashumi amawaka eekhilomitha. Isixa se-gap sikhula ngokuthe ngcembe kunye nokugqoka kwe-shaft kunye nokuthwala.

Nangona i-crankshaft ikhuselwe ngokuthambisa i-oyile kunye nokukhutshwa kwe-oyile, ngamanye amaxesha i-crankshaft ivalwa ngokungaqhelekanga ngenxa yoxinzelelo lweoyile enganelanga, i-oyile emdaka, ukuchaneka okungafanelekanga, umphezulu wonxibelelwano ongalinganiyo, ukugqiba okunganelanga kunye nokuchaneka.

I-crankshaft yemoto inokujongwa ngeqonga lokulinganisa, ngokukodwa ukubona iqondo layo le-buckling, elinokulinganiswa ngetafile yegiya yokujika. Kukho kwakhona ukunxitywa kwejenali yayo ephambili kunye nejenali yentonga yokudibanisa, enokulinganiswa nge-micrometer. I-crankshaft iya kuvelisa ukunxiba kwejenali ngexesha lokusetyenziswa, ukwenza ngaphandle kokujikeleza kunye neecones. Oku kulandelayo malunga nendlela yokufumanisa:

1. Sula i-crankshaft ngokucokisekileyo, ngokukodwa inxalenye yokuhlola kufuneka ingabi neoli, kwaye inxalenye yokulinganisa kufuneka ibe kude nomngxuma weoli;

2. Umlinganiselo wokutenxa okungqukuva: Sebenzisa i-micrometer yangaphandle ukwenza umlinganiselo wamanqaku amaninzi kwindawo enye enqamlezileyo apho ijenali inxitywe kakhulu (umlinganiselo wokuqala kumacala omabini omngxuma weoyile yejenali, uze ujikethe i-900), phakathi komngxuma omkhulu. Idayamitha kunye nedayamitha encinci Isiqingatha somahluko kukutenxa okungqukuva;

3. Umlinganiselo we-Cylindricity deviation measurement: i-multi-point measurement kwicandelo elifanayo le-longitudinal yejenali, isiqingatha somahluko phakathi kwe-diameter enkulu kunye ne-diameter encinci yi-cylindricity deviation.
