Izingxenye ezigqokile ze-crankshaft ikakhulukazi ziyijenali eyinhloko kanye namadevu e-shaft yenduku. Ukushintshisana kokunyakaza okuhambisanayo kwepiston yenjini enama-stroke amane kanye nokuzungezisa kwe-crankshaft kuzodala ukuthi i-crankshaft ihlikihlwe ngama-engeli ahlukene. Lokhu kungqubuzana kuye kwehliswa kwaba sezingeni eliphansi ngaphansi kwesenzo samafutha okugcoba.

Lapho injini isebenza ngesivinini esikhulu futhi ngaphansi komthwalo osindayo, izinga lokushisa lesihlahla esithwalayo liyakhula futhi ukwanda okushisayo kwenzeka. Ngakho-ke, igebe elithile kufanele lishiywe phakathi kwe-bearing kanye ne-bearing ukuvikela i-crankshaft. Igebe phakathi kweshaft nehlathi alikwazi ukuqinisekisa ukuthi injini igijima amashumi ezinkulungwane zamakhilomitha. Inani legebe liyakhula kancane kancane ngokugqoka kwe-shaft kanye nokuthwala.

Nakuba i-crankshaft ivikelwe ngamafutha okugcoba kanye ne-bearing clearance, ngezinye izikhathi i-crankshaft ihlushwa ukuguga okungavamile ngenxa yokucindezela kawoyela okunganele, uwoyela ongcolile, imvume yokuthwala engafanele, indawo yokuxhumana engalingani, isiphetho esinganele kanye nokunemba.

I-crankshaft yemoto ingahlolwa kusetshenziswa i-calibration platform, ikakhulukazi ukuze kubonwe izinga layo le-buckling, elingalinganiswa netafula legiya eliphendukayo. Kukhona futhi ukuguga kwejenali yayo eyinhloko kanye nejenali yenduku yokuxhuma, engalinganiswa nge-micrometer. I-crankshaft izokhiqiza ukugqokwa kwejenali ngesikhathi sokusetshenziswa, ukwenza ngaphandle kokujikeleza kanye nama-cones. Okulandelayo kumayelana nendlela yayo yokuthola:

1. Sula i-crankshaft kahle, ikakhulukazi ingxenye yokuhlola kufanele ingabi namafutha, futhi ingxenye yokulinganisa kufanele ibe kude nomgodi wamafutha;

2. Isilinganiso sokuchezuka kokuyindilinga: Sebenzisa i-micrometer yangaphandle ukuze wenze isilinganiso samaphuzu amaningi endaweni efanayo lapho iphephabhuku ligqokwe kakhulu (isilinganiso sokuqala kuzo zombili izinhlangothi zembobo kawoyela yejenali, bese uzungezisa 900), phakathi kwesikhulu ububanzi kanye nobubanzi obuncane Ingxenye yomehluko ukuchezuka kokuyindilinga;

3. Isilinganiso sokuchezuka kwe-Cylindricity: ukulinganisa kwamaphoyinti amaningi esigabeni esifanayo sobude bejenali, uhhafu womehluko phakathi kobubanzi obukhulu kanye nobubanzi obuncane ukuchezuka kwe-cylindricity.
