Ibikoresho bya crankshaft (harimo n'ibinyamakuru by'ingenzi n'ibinyamakuru by'inkoni bihuza) ni ibintu by'ingenzi mu kohereza ingufu za moteri. Dukurikije ibisabwa n'ibipimo ngenderwaho bya GB/T 24595-2020 ku rwego rw'igihugu, ubukana bw'ibyuma bikoreshwa mu gukaraba bigomba kugenzurwa neza nyuma yo kuzimya no gushyushya. Inganda z'imodoka zo mu gihugu no mu mahanga zifite amahame asobanutse y'ubukana bw'ibinyamakuru bya crankshaft, kandi gupima ubukana ni igikorwa cy'ingenzi mbere yuko ibicuruzwa biva mu ruganda.
Dukurikije GB/T 24595-2020 Steel Bars for Automobile Crankshafts and Camshafts, ubukana bw'ubuso bw'ama-crankshaft journal bugomba kuba bwujuje ibisabwa na HB 220-280 nyuma yo kuzimya no gushyushya.
ASTM A1085 isanzwe (yatanzwe n'Umuryango w'Abanyamerika ushinzwe ibizamini n'ibikoresho, ASTM) ivuga ko ubukana bw'udupapuro tw'inkoni duhuza ku modoka zitwara abagenzi bugomba kuba ≥ HRC 28 (bihuye na HB 270).
Byaba ari ukureba uruhande rw'umusaruro mu kwirinda ikiguzi cyo kuvugurura no kurinda izina ryiza, uruhande rw'umukoresha mu gukumira igihe gito cyo gukoresha moteri n'ingaruka zo kwangirika kwayo, cyangwa uruhande rw'inyuma yo kugurisha mu kwirinda impanuka z'umutekano, ni ngombwa kubuza ibicuruzwa bitujuje ubuziranenge kwinjira ku isoko no gukora isuzuma ry'ubukana bwa crankshaft hakurikijwe amabwiriza.
Igipimo cy’ubukana cya Rockwell cyihariye ku byuma bipima ubukana byakozwe n’ikigo cyacu gikora imirimo yose yikora ku buryo bwikora nko kugenda kw’intebe y’akazi ya crankshaft, igerageza, no kohereza amakuru. Gishobora gukora vuba ibizamini by’ubukana bya Rockwell (urugero, HRC) ku bice bitandukanye by’icyuma gipima ubukana.
Ikoresha sisitemu yo kugenzura ikozwe mu buryo bw'ikoranabuhanga ifunganye mu gupakira no gupima, iyi test ikora ikoranabuhanga ryikora ku buryo bwikora hamwe n'akabuto kamwe (kwegera workpiece, gushyiramo load, kubungabunga load, gusoma no kurekura workpiece byose bikorwa mu buryo bwikora, bigakuraho amakosa y'abantu).
Sisitemu yo gufunga crankshaft itanga uburyo bwo kwihuta no kugenda imbere n'inyuma, hamwe n'ingendo zishobora gutoranywa ibumoso, iburyo, no hejuru no hasi, bigatuma hapimwa aho crankshaft iherereye.
Uburyo bworoshye bwo gufunga icyuma gifunga icyuma gitanga uburyo bworoshye bwo kwifunga, bikuraho ibyago byo kunyerera kw'ibikoresho mu gihe cyo gupima.
