Iijenali zecrankshaft (kubandakanywa iijenali eziphambili kunye neejenali zentonga ezidibanisayo) zizinto eziphambili zokuhambisa amandla enjini. Ngokuhambelana neemfuno zomgangatho wesizwe we-GB / T 24595-2020, ukuqina kweentsimbi zentsimbi ezisetyenziselwa i-crankshafts kufuneka zilawulwe ngokungqongqo emva kokucima kunye nokuvutha. Omabini amashishini eemoto asekhaya nakwamanye amazwe anemigangatho egunyazisiweyo ecacileyo yobulukhuni beejenali zecrankshaft, kwaye uvavanyo lobulukhuni yinkqubo eyimfuneko phambi kokuba imveliso iphume kumzi-mveliso.
Ngokutsho kwe-GB/T 24595-2020 yeeBar zeNsimbi ze-Automobile Crankshafts kunye neeCamshafts, ubulukhuni bomphezulu beejenali ze-crankshaft buya kuhlangabezana nemfuneko ye-HB 220-280 emva kokucinywa kunye nokuthoba.
Umgangatho we-ASTM A1085 (okhutshwe yi-American Society for Testing and Materials, i-ASTM) ichaza ukuba ukuqina kweejenali zentonga zokudibanisa kwi-crankshafts yemoto yabahambi kuya kuba ≥ HRC 28 (ehambelana ne-HB 270).
Nokuba ngokwembono yecala imveliso ekuphepheni iindleko rework kunye nokukhusela isidima umgangatho, icala lomsebenzisi ekuthinteleni bufutshane ubomi inkonzo injini kunye nemingcipheko ukusilela, okanye icala emva-intengiso ukuphepha iingozi zokhuseleko, kunyanzelekile ukuba ukuthintela iimveliso ezikumgangatho ophantsi ekungeneni kwimarike kwaye uqhube uvavanyo lobulukhuni be-crankshaft ngokuhambelana ngokungqongqo nemigangatho.
Umvavanyi wobulukhuni be-Rockwell okhethekileyo kwii-crankshafts eziveliswe yinkampani yethu ibona imisebenzi ezenzekelayo ngokupheleleyo efana nokuhamba kwe-crankshaft workbench, uvavanyo, kunye nokuhanjiswa kwedatha. Inokwenza ngokukhawuleza iimvavanyo zobulukhuni be-Rockwell (umzekelo, i-HRC) kwiileya eziqinileyo zeendawo ezahlukeneyo ze-crankshaft.
Isebenzisa inkqubo yokulawula i-electronic-loop evaliweyo yokulayisha kunye nokuvavanya, lo mvavanyi uzenzekela ngokupheleleyo ngeqhosha elinye (ukusondela kwi-workpiece, ukufaka umthwalo, ukugcina umthwalo, ukufunda, kunye nokukhulula i-workpiece yonke into eyenziwa ngokuzenzekelayo, ukuphelisa impazamo yomntu).
Inkqubo ye-crankshaft clamping inikezela ngokuzenzekela kunye nentshukumo yezandla phambili nangasemva, kunye nentshukumo ekhethiweyo ekhohlo, ekunene, kunye naphezulu naphantsi, evumela umlinganiselo wayo nayiphi na indawo ye-crankshaft.
Isitshixo sendawo yecrankshaft esizikhethelayo sibonelela ngokuzivalela ngokufanelekileyo, sisusa umngcipheko wokutyibilika kwesixhobo sokusebenza ngexesha lomlinganiso.
