Amajenali e-crankshaft (kufaka phakathi amajenali amakhulu kanye namajenali enduku yokuxhuma) ayizingxenye ezibalulekile zokudlulisa amandla enjini. Ngokuhambisana nezidingo ze-GB/T 24595-2020 ejwayelekile kazwelonke, ubulukhuni bezinsimbi zensimbi ezisetshenziselwa ama-crankshaft kumele bulawulwe ngokuqinile ngemva kokucima nokushisa. Izimboni zezimoto zasekhaya nezamazwe ngamazwe zinezindinganiso ezicacile ezidingekayo zobulukhuni bamajenali e-crankshaft, futhi ukuhlolwa kobulukhuni kuyinqubo ebalulekile ngaphambi kokuba umkhiqizo uphume efektri.
Ngokusho kwe-GB/T 24595-2020 Steel Bars for Automobile Crankshafts and Camshafts, ubulukhuni bomphezulu wamajenali e-crankshaft kufanele buhlangabezane nemfuneko ye-HB 220-280 ngemva kokucisha nokushisa.
I-ASTM A1085 ejwayelekile (ekhishwe yi-American Society for Testing and Materials, ASTM) ibeka ukuthi ubulukhuni bamajenali enduku yokuxhuma ama-crankshaft ezimoto zabagibeli kufanele bube yi-≥ HRC 28 (okuhambisana ne-HB 270).
Kungakhathaliseki ukuthi ngokombono wohlangothi lokukhiqiza ekugwemeni izindleko zokulungisa kabusha nokuvikela idumela lekhwalithi, uhlangothi lomsebenzisi ekuvimbeleni impilo yenkonzo yenjini emfushane kanye nezingozi zokwehluleka, noma uhlangothi lwangemva kokuthengisa ekugwemeni izingozi zokuphepha, kubalulekile ukuvimbela imikhiqizo engaphansi kwekhwalithi ukuthi ingene emakethe futhi yenze ukuhlolwa kobulukhuni be-crankshaft ngokuhambisana ngokuqinile nezindinganiso.
Isihloli sokuqina kweRockwell esikhethekile sama-crankshaft akhiqizwa yinkampani yethu senza imisebenzi ezenzakalelayo ngokugcwele njengokunyakaza kwebhentshi lokusebenzela le-crankshaft, ukuhlola, kanye nokudluliswa kwedatha. Singenza ngokushesha ukuhlolwa kokuqina kweRockwell (isb., i-HRC) ezingqimbeni eziqinile zezingxenye ezahlukene ze-crankshaft.
Isebenzisa uhlelo lokulawula oluvaliwe lwe-elekthronikhi lokulayisha nokuhlola, lo mhloli uzenzakalelayo ngokuphelele ngenkinobho eyodwa (ukusondela ku-workpiece, ukufaka umthwalo, ukugcina umthwalo, ukufunda, nokukhulula i-workpiece konke kwenziwa ngokuzenzakalelayo, kususa amaphutha omuntu).
Uhlelo lokubopha i-crankshaft lunikeza ukunyakaza okuzenzakalelayo nokwesandla ukuya phambili nokubuyela emuva, ngokunyakaza okukhethiwe kwesobunxele, kwesokudla, kanye nokwenyuka nokwehla, okuvumela ukukalwa kwanoma iyiphi indawo ye-crankshaft.
Ukukhiya kwesikhundla se-crankshaft okukhethwa kukho kunikeza ukuzikhiya okulula, kususa ingozi yokushelela kwezingxenye zomsebenzi ngesikhathi sokulinganisa.
