Ibinyamakuru bya crankshaft (harimo ibinyamakuru nyamukuru no guhuza ibinyamakuru inkoni) nibice byingenzi byo kohereza ingufu za moteri. Dukurikije ibisabwa byigihugu GB / T 24595-2020, ubukana bwibyuma bikoreshwa mumashanyarazi bigomba kugenzurwa cyane nyuma yo kuzimya no gushyuha. Inganda z’imbere mu gihugu ndetse no mu mahanga zifite ibipimo ngenderwaho bisobanutse ku gukomera kw'ibinyamakuru bya crankshaft, kandi gupima ubukana ni inzira y'ingenzi mbere yuko ibicuruzwa biva mu ruganda.
Ukurikije GB / T 24595-2020 Ibyuma bya Steel ya Automobile Crankshafts na Camshafts, ubukana bwo hejuru bwibinyamakuru bya crankshaft buzuza ibisabwa na HB 220-280 nyuma yo kuzimya no gutwarwa.
Ubusanzwe ASTM A1085 (yatanzwe na Sosiyete y'Abanyamerika ishinzwe ibizamini n'ibikoresho, ASTM) iteganya ko ubukana bwo guhuza ibinyamakuru by'inkoni ku modoka zitwara abagenzi bizaba ≥ HRC 28 (bihuye na HB 270).
Haba ukurikije uruhande rwumusaruro mukwirinda ibiciro byakazi no kurinda izina ryiza, uruhande rwumukoresha mukurinda igihe gito cya serivisi ya moteri nigihe cyokunanirwa, cyangwa uruhande nyuma yo kugurisha mukwirinda impanuka zumutekano, ni ngombwa kubuza ibicuruzwa bitujuje ubuziranenge kwinjira mumasoko no gukora ibizamini bya crankshaft bikurikije amahame.
Ikizamini cya Rockwell cyihariye cyihariye cya crankshafts cyakozwe nisosiyete yacu kimenya ibikorwa byikora byuzuye nko kugenda kwakazi ka crankshaft, kugerageza, no kohereza amakuru. Irashobora gukora byihuse ibizamini bya Rockwell (urugero, HRC) kumurongo ukomeye wibice bitandukanye bya crankshaft.
Ikoresha uburyo bwa elegitoronike bufunze-bugenzura sisitemu yo gupakira no kugerageza, iki kizamini cyikora rwose hamwe na buto imwe (kwegera igihangano, gukoresha umutwaro, kugumana umutwaro, gusoma, no kurekura ibihangano byose bikorwa mu buryo bwikora, bikuraho amakosa yabantu).
Sisitemu yo gufatisha crankshaft itanga ibyuma byikora nintoki imbere ninyuma yinyuma, hamwe nibishobora guhitamo ibumoso, iburyo, no hejuru no kumanuka, byemerera gupima aho ariho hose.
Guhitamo umwanya wa frankshaft itanga uburyo bworoshye bwo kwifungisha, bikuraho ingaruka zo kunyerera kumurimo mugihe cyo gupima.
