Iijenali ze-crankshaft (kuquka iijenali eziphambili kunye neejenali zentonga yokudibanisa) zizinto ezibalulekileyo zokudlulisa amandla enjini. Ngokuhambelana neemfuno zomgangatho wesizwe we-GB/T 24595-2020, ubunzima beebha zentsimbi ezisetyenziselwa ii-crankshaft kufuneka bulawulwe ngokungqongqo emva kokucima kunye nokushisa. Amashishini eemoto asekhaya nakwamanye amazwe anemigangatho ecacileyo yobunzima beejenali ze-crankshaft, kwaye uvavanyo lobunzima yinkqubo ebalulekileyo ngaphambi kokuba imveliso iphume kumzi-mveliso.
Ngokwe-GB/T 24595-2020 Steel Bars for Automobile Crankshafts and Camshafts, ubulukhuni bomphezulu weejenali ze-crankshaft buya kuhlangabezana nemfuneko ye-HB 220-280 emva kokucinywa nokufuthwa.
I-ASTM A1085 esemgangathweni (ekhutshwe yi-American Society for Testing and Materials, ASTM) ichaza ukuba ubunzima beejenali zentonga yokudibanisa kwii-crankshafts zemoto yabakhweli kufuneka bube yi-≥ HRC 28 (ehambelana ne-HB 270).
Nokuba ngokwembono yecandelo lemveliso ekuphepheni iindleko zokulungisa nokukhusela udumo lomgangatho, icala lomsebenzisi ekuthinteleni ubomi obufutshane benkonzo yenjini kunye nemingcipheko yokungaphumeleli, okanye icala emva kokuthengisa ekuphepheni iingozi zokhuseleko, kubalulekile ukuthintela iimveliso ezikumgangatho ophantsi ukuba zingangeni kwimarike kwaye kwenziwe uvavanyo lobunzima be-crankshaft ngokuhambelana nemigangatho.
Isixhobo sokuvavanya ubulukhuni saseRockwell esikhethekileyo kwii-crankshafts eziveliswa yinkampani yethu senza imisebenzi ezenzekelayo ngokupheleleyo efana nokuhamba kwebhentshi yokusebenza ye-crankshaft, uvavanyo, kunye nokudluliselwa kwedatha. Singenza ngokukhawuleza uvavanyo lobulukhuni baseRockwell (umz., i-HRC) kwiileya eziqinileyo zeendawo ezahlukeneyo ze-crankshaft.
Isebenzisa inkqubo yokulawula i-electronic closed-loop yokulayisha nokuvavanya, le tester izenzekelayo ngokupheleleyo ngeqhosha elinye (ukusondela kwindawo yokusebenza, ukufaka umthwalo, ukugcina umthwalo, ukufunda, nokukhulula indawo yokusebenza konke kwenziwa ngokuzenzekelayo, ukususa iimpazamo zomntu).
Inkqubo yokubamba i-crankshaft inika intshukumo ezenzekelayo neyenziwe ngesandla ukuya phambili nangasemva, kunye neentshukumo ezikhethiweyo zasekhohlo, ekunene, naphezulu nasezantsi, okuvumela ukulinganiswa kwendawo ye-crankshaft.
Isitshixo sendawo ye-crankshaft esinokuzikhethela sibonelela ngokuzitshixa okulula, sisusa umngcipheko wokutyibilika kwesixhobo somsebenzi ngexesha lokulinganisa.
