Majenari e crankshaft (kusanganisira majenari makuru uye majenari ekubatanidza tsvimbo) ndiwo akakosha ekufambisa simba reinjini. Zvinoenderana nezvinodiwa zveNational standard GB/T 24595-2020, kuomarara kwesimbi mbariro dzinoshandiswa crankshafts dzinofanira kunyatsodzorwa mushure mekudzima uye kupisa. Maindasitiri emotokari emudzimba neekunze ane akajeka anosungirwa zviyero zvekuoma kwemajenari ecrankshaft, uye kuyedzwa kwekuomarara inzira yakakosha chigadzirwa chisati chabuda mufekitori.
Zvinoenderana neGB/T 24595-2020 Steel Bars for Automobile Crankshafts and Camshafts, kuomarara kwepamusoro kwemajenari ecrankshaft kuchasangana nezvinodiwa zveHB 220-280 mushure mekudzima nekudziya.
Iyo yakajairwa ASTM A1085 (yakabudiswa neAmerican Society for Testing and Materials, ASTM) inotaura kuti kuomarara kwekubatanidza majenarari etsvimbo emota dzevatyairi crankshafts kuchave ≥ HRC 28 (inoenderana neHB 270).
Zvingave kubva pamaonero edivi rekugadzira mukudzivirira mutengo wekugadzirisa zvakare uye kuchengetedza mukurumbira wemhando, mushandisi mukudzivirira kupfupikiswa kwehupenyu hwesevhisi yeinjini uye njodzi yekutadza, kana chikamu chekutengesa-mukudzivirira njodzi dzekuchengetedza, zvakakosha kurambidza zvigadzirwa zvisingaite kupinda mumusika uye kuongorora kuomarara kwecrankshaft zvinoenderana nezviyero.
Iyo Rockwell hardness tester yakasarudzika ye crankshafts inogadzirwa nekambani yedu inoona zvizere otomatiki mabasa akadai sekufamba kwe crankshaft workbench, kuyedza, uye kutumira data. Inogona kukurumidza kuita Rockwell kuomarara bvunzo (semuenzaniso, HRC) pane akaomeswa akaomeswa ezvikamu zvakasiyana zve crankshaft.
Inoshandisa yemagetsi yakavharwa-loop yekudzora sisitimu yekurodha uye yekuyedza, iyi tester izere otomatiki nebhatani rimwe (kuswedera kune workpiece, kuisa mutoro, kuchengetedza mutoro, kuverenga, uye kuburitsa workpiece zvese zvinoitwa otomatiki, kubvisa kukanganisa kwevanhu).
Iyo crankshaft clamping system inopa otomatiki uye manyore kumberi uye kumashure kufamba, ine inosarudzwa kuruboshwe, kurudyi, uye kumusoro uye pasi mafambiro, ichibvumira kuyerwa kwechero crankshaft nzvimbo.
Inosarudzika crankshaft chinzvimbo chekiyi inopa nyore kuzvivharira, kubvisa njodzi yekutsvedza kweworkpiece panguva yekuyera.
