Amajenali e-crankshaft (okuhlanganisa namajenali amakhulu kanye namajenali enduku yokuxhuma) ayizingxenye ezibalulekile zokudlulisa amandla enjini. Ngokuhambisana nezidingo ze-GB/T 24595-2020 ejwayelekile kazwelonke, ukuqina kwezinsimbi zensimbi ezisetshenziselwa ama-crankshafts kumele kulawulwe ngokuqinile ngemuva kokucisha nokufutheka. Zombili izimboni zezimoto zasekhaya nezamazwe ngamazwe zinemigomo ecacile eyisibopho yobulukhuni bamajenali e-crankshaft, futhi ukuhlola ubulukhuni kuyinqubo ebalulekile ngaphambi kokuba umkhiqizo uphume efekthri.
Ngokuvumelana ne-GB/T 24595-2020 Steel Bars for Automobile Crankshafts and Camshafts, ukuqina okungaphezulu kwamajenali e-crankshaft kuzohlangabezana nemfuneko ye-HB 220-280 ngemva kokucisha kanye nokushisa.
I-ASTM A1085 ejwayelekile (ekhishwe yi-American Society for Testing and Materials, ASTM) ibeka ukuthi ubulukhuni bamajenali enduku yokuxhuma ama-crankshaft ezimoto zabagibeli kuzoba ≥ HRC 28 (okuhambisana ne-HB 270).
Kungakhathaliseki ukuthi ngokombono wohlangothi lokukhiqiza ekugwemeni izindleko zokusebenza kabusha nokuvikela isithunzi sekhwalithi, uhlangothi lomsebenzisi ekuvimbeleni impilo yesevisi yenjini efinyeziwe kanye nezingozi zokwehluleka, noma uhlangothi lwangemva kokuthengisa ekugwemeni izingozi zokuphepha, kubalulekile ukuvimbela imikhiqizo esezingeni eliphansi ukuthi ingangeni emakethe futhi ihlole ubulukhuni be-crankshaft ngokuvumelana nezindinganiso.
I-Rockwell hardness tester eyisipesheli sama-crankshafts akhiqizwa inkampani yethu ibona imisebenzi ezenzakalelayo njengokunyakaza kwebhentshi lokusebenzela le-crankshaft, ukuhlola, nokudluliswa kwedatha. Ingenza ngokushesha ukuhlola kokuqina kwe-Rockwell (isb, i-HRC) ezingqimbeni eziqinile zezingxenye ezihlukahlukene ze-crankshaft.
Isebenzisa uhlelo lokulawula iluphu oluvaliwe lwe-elekthronikhi ukuze kulayishwe futhi kuhlolwe, lo mhloli uzenzakalela ngokugcwele ngenkinobho eyodwa (ukusondela endaweni yokusebenza, ukufaka umthwalo, ukugcina umthwalo, ukufunda, nokukhulula ucezu lokusebenza konke kwenziwa ngokuzenzakalelayo, kuqeda iphutha lomuntu).
Isistimu ye-crankshaft clamping inikezela ngokunyakaza okuzenzakalelayo nokuya ngesandla nokuya emuva, ngokukhetha kwesokunxele, kwesokudla, naphezulu naphansi, okuvumela ukukalwa kwanoma iyiphi indawo ye-crankshaft.
Ukukhiya kwesikhundla se-crankshaft ongakukhetha kuhlinzeka ngokuzivala okulula, okuqeda ubungozi bokushelela kocezu lokusebenza ngesikhathi sokulinganisa.
