Seimwe yezvikamu zvakakosha zveinjini, crankshaft inotakura chiitiko chakasanganiswa chekuchinjanisa kukotama uye kuchinjisa mitoro yekutenderera panguva yekufamba. Kunyanya, iyo shanduko fillet pakati pejenari uye crank inotakura zvakanyanya kuchinjisa kushushikana, uye crankshaft fillet chinzvimbo chinowanzo konzera crankshaft kutyoka nekuda kwekunyanya kunetseka. Naizvozvo, mune crankshaft dhizaini nekugadzira maitiro, zvinodikanwa kusimbisa iyo crankshaft fillet chinzvimbo kuti uvandudze kuita kwese kwe crankshaft. Crankshaft fillet kusimbisa kazhinji inotora induction kuomesa, nitriding kurapwa, fillet kupfura peening, fillet rolling uye laser shock.

Shot blasting inoshandiswa kubvisa oxide scale, ngura, jecha uye firimu rependi rekare pane zvigadzirwa zvesimbi zvepakati uye zvakakura uye zvinokandwa zvine ukobvu husingasviki 2mm kana zvisingadi zviyero nemakona. Iyo inzira yekuchenesa isati yavhara pamusoro. Shot peening inonziwo shot peening, inova imwe yenzira dzinoshanda dzekudzikisa kuneta kwezvikamu uye kuwedzera hupenyu.

Shot peening yakakamurwa kuita pfuti peening uye jecha blasting. Uchishandisa kuputika kwepfuti pakurapwa kwepamusoro, simba rekuita rakakura, uye kuchenesa kuri pachena. Zvisinei, kurapwa kwepureti yakatetepa workpieces kuburikidza nepfuti peening inogona nyore kukanganisa workpiece, uye pfuti yesimbi inorova pamusoro peworkpiece (kungave kupfurwa kunoputika kana kupfurwa kudongorera) kukanganisa simbi substrate. Nemhaka yokuti Fe3O4 neFe2O3 havana plastiki, vanobvisa mushure mekuputsika, uye firimu yemafuta iThe base material deforms panguva imwe chete, saka kuputika kwepfuti uye kuputika kwepfuti hakugoni kubvisa zvachose tsvina yemafuta pane basa rekushanda nemafuta emafuta. Pakati peiyo iripo nzira yekurapa pamusoro pemaworkpieces, yakanakisa yekuchenesa mhedzisiro ndeye sandblasting.
