Ma "crankshaft journals" (kusanganisira ma "main journals" nema "connecting rod journals") zvinhu zvakakosha pakutumira simba reinjini. Zvichienderana nezvinodiwa ne standard GB/T 24595-2020 yenyika, kuomarara kwesimbi dzinoshandiswa kuma "crankshafts" kunofanira kudzorwa zvakasimba mushure mekudzima nekudziya. Maindasitiri emotokari emuno neekunze kwenyika ane mitemo yakajeka yekuomarara kwema "crankshaft journals", uye kuyedzwa kwekuomarara inzira inokosha chigadzirwa chisati chabuda mufekitori.
Zvichienderana neGB/T 24595-2020 Steel Bars dzeMota Crankshafts neCamshafts, kuomarara kwepamusoro pemajenari ecrankshaft kunofanira kusangana nezvinodiwa neHB 220-280 mushure mekudzima nekudziya.
Mutemo weASTM A1085 (wakabudiswa neAmerican Society for Testing and Materials, ASTM) unoti kuoma kwemabhatani ekubatanidza tsvimbo dzemotokari dzevafambi kunofanira kuva ≥ HRC 28 (inoenderana neHB 270).
Kungave kubva pamaonero erutivi rwekugadzira mukudzivirira mari yekugadzirisa patsva uye kuchengetedza mukurumbira wemhando yepamusoro, divi remushandisi mukudzivirira kupfupikiswa kwenguva yebasa reinjini uye njodzi dzekukundikana, kana divi remushure mekutengesa mukudzivirira tsaona dzekuchengetedza, zvakakosha kurambidza zvigadzirwa zvisina mwero kuti zvisapinde mumusika uye kuita bvunzo dzehukukutu hwecrankshaft zvichienderana nezvinodiwa.
Chiyedzo cheRockwell hardness tester chakagadzirirwa macrankshafts akagadzirwa nekambani yedu chinoita mabasa ega ega akadai sekufamba kwebhenji rebasa recrankshaft, kuyedza, uye kutumira data. Chinogona kukurumidza kuita Rockwell hardness tests (semuenzaniso, HRC) pazvikamu zvakasiyana-siyana zvecrankshaft zvakaomeswa.
Inoshandisa sisitimu yekudzora yemagetsi yakavharwa-loop yekurodha nekuyedza, tester iyi inogadzirwa otomatiki nebhatani rimwe chete (kusvika pabasa, kuisa mutoro, kuchengetedza mutoro, kuverenga, uye kusunungura basa zvese zvinoitwa otomatiki, zvichibvisa kukanganisa kwevanhu).
Sisitimu yekusunga crankshaft inopa kufamba otomatiki uye nemaoko kuenda mberi nekudzokera shure, nemafambiro anosarudzwa kuruboshwe, kurudyi, uye kumusoro nekudzika, zvichibvumira kuyerwa kwenzvimbo chero ipi zvayo yecrankshaft.
Kiyi yekuisa crankshaft ine sarudzo inoita kuti ikwanise kuzvivharira yoga, zvichibvisa njodzi yekutsvedza kwechinhu panguva yekuyerwa.
