Zvikamu zvakasakara zve crankshaft ndizvo zvinonyanya kuve magazini makuru uye yekubatanidza tsvimbo shaft ndebvu. Kuchinjana kwekudzokororwa kwepiston yeinjini yechina-stroke uye kutenderera kwe crankshaft kuchaita kuti crankshaft ikwekwe pamakona akasiyana. Uku kukakavara kwakaderedzwa kusvika padanho rakaderera pasi pechiito chemafuta ekuzora.

Kana injini ichimhanya nekumhanya kukuru uye pasi pemutoro unorema, tembiricha yegwenzi rinotakura inowedzera uye kuwedzera kwekupisa kunoitika. Naizvozvo, imwe gwanza rinofanira kusiiwa pakati pekutakura uye kutakura kuchengetedza crankshaft. Mukaha uripo pakati peshaft negwenzi haugone kuve nechokwadi chekuti injini inomhanya kwemakumi ezviuru zvemakiromita. Kuwanda kwegomba zvishoma nezvishoma kunowedzera nekupfeka kwe shaft uye kutakura.

Kunyangwe iyo crankshaft yakadzivirirwa nemafuta ekuzora uye kutakura clearance, dzimwe nguva crankshaft inotambura kupfeka zvisina kujairika nekuda kwekusakwana kwemafuta ekumanikidza, mafuta akasviba, isina kufanira kutakura clearance, kusaenzana kwekubata kumeso, kusakwana kupera uye kunyatsoita.

Iyo crankshaft yemotokari inogona kuongororwa necalibration papuratifomu, kunyanya kuona dhigirii yayo yebuckling, iyo inogona kuyerwa neinotendeuka giya tafura. Iko kune zvakare kupfeka kwejenari rayo guru uye yekubatanidza tsvimbo jenari, iyo inogona kuyerwa ne micrometer. Iyo crankshaft inoburitsa jenari kupfeka panguva yekushandiswa, kugadzira kunze-kwe-kutenderera uye makoni. Izvi zvinotevera nzira yekuona kwayo:

1. Pukuta crankshaft zvakakwana, kunyanya chikamu chekuongorora chinofanira kunge chisina mafuta, uye chikamu chekuyera chinofanira kunge chiri kure negomba remafuta;

2. Kuyera kutsauka kwekutenderera: Shandisa micrometer yekunze kuita chiyero che-multi-point pachikamu chimwe chete chemuchinjiko apo jenari yakapfekwa zvakanyanya (chiyero chekutanga kumativi ese egomba remafuta rejenari, wozotenderera 900), pakati pehombe. dhayamita uye dhayamita diki Hafu yemusiyano ndiko kutsauka kwekutenderera;

3. Cylindricity deviation measurement: multi-point measurement pane imwechete longitudinal chikamu chejenari, hafu yemusiyano pakati pedhayamita yakakura uye diki dhayamita ndiyo cylindricity deviation.
