I-crankshaft yenye yezona ndawo zibalulekileyo kwi-injini yokutsha yangaphakathi, kwaye ubomi bayo benkonzo buhlala bumisela ubomi benkonzo ye-injini yokutsha yangaphakathi. Ngo-1920, i-American Clark Company yasebenzisa itekhnoloji yokwenziwa lukhuni kwetekhnoloji eyayilwa kutshanje ukwenzela ukuqina kwejenali ye-crankshaft, eyaphucula kakhulu ukuxhathisa kwe-crankshaft, ngaloo ndlela iphucula ubomi bokusebenza be-injini yokutsha yangaphakathi.

Kumashumi eminyaka akutshanje, ukophuka kokudinwa kwecrankshaft kuye kwabonakala ngakumbi, kwaye imithombo yokudinwa iyenzeka ikakhulu kwiikona ezingqukuva zecrankshaft yejenali yentonga yokudibanisa. Ngenxa yesi sizathu, abavelisi abaninzi baye bacebisa iimfuno zokuphucula amandla okukhathala kwe-crankshaft. Isitshixo sokuphucula amandla okudinwa kwe-crankshaft kukwandisa uxinzelelo olushiyekileyo lwefillet ye-crankshaft. Ukwenziwa lukhuni kweefilts zecrankshaft (kubandakanywa nejenali) yeyona ndlela ikhethwayo yokufumana uxinzelelo olukhulu olushiyekileyo lwe>600MPa kwiifilts. Inkampani yaseJapan yenze uthotho lovavanyo lokudinwa lokugoba kwi-crankshaft ye-injini yokutshisa yangaphakathi. Uvavanyo lubonakalise ukuba i-crankshaft ejikelezisiweyo eyenziwe lukhuni inamandla okudinwa aphezulu (996MPa), amandla okudinwa kwecrankshaft ajikelezileyo yeyesibini (890MPa), kwaye i-nitrided crankshaft yeyesithathu (720MPa). Iinkampani zaseMelika nazo zinedatha efanayo. I-Crankshaft fillet quenching ngokuqhelekileyo isebenzisa "i-half-turn inductor" yokucima, eyaziwa ngokuba yi-Elotherm (Elotherm) yokucima indlela. Kungenxa yokuba i-sensor ifakwe kwijenali, kwaye i-crankshaft iyafudumala kwaye amanzi acinywe ngexesha lokujikeleza (kukwakho imeko apho ijenali ye-crankshaft ishushu kwiqondo lokushisa lokucima kwaye iguqulelwe echibini lokupholisa kunye nokucima). Le ndlela ayiququzeleli kuphela ukungena kunye nokuphuma kwe-sensor ye-crankshaft, yenza lula isenzo sesixhobo sokucima umatshini, kodwa iphinda isombulule iintanda ze-oyile, ububanzi obungalinganiyo bendawo enzima, ubukhulu obungalinganiyo boluhlu oluqinileyo. deformation.

Abantu abakushishino ngokubanzi bakholelwa ukuba indlela yokucima i-Eluosen yinkqubela phambili enkulu kwitekhnoloji yokucima i-crankshaft. Idatha ibonisa ukuba ukwenziwa lukhuni kweejenali ze-crankshaft kunokunyusa ubomi be-injini ukuya kwiiyure ezingama-8000, ngelixa ukucinywa kwejenali kunye neefayili kunokunyusa ubomi be-injini ukuya kwiiyure ze-10,000. Itekhnoloji ephambili ekufuneka isonjululwe ukufezekisa ukucima i-fillet yitekhnoloji yokuhambisa amandla. I-Crankshaft "i-half-turn inductor" yokucima ibandakanya ubugcisa obuninzi, njengombane wokuguqula umbane, isixhobo sokucima umatshini kunye ne-inductor, njl. Ezi teknoloji nazo zibaluleke kakhulu, kodwa ezi teknoloji ziye zaqala ukusonjululwa kwilizwe lam ekuqaleni kwee-1980.

Ngokucacileyo, ukufudumeza okucimayo kwefillet ye-crankshaft kufuneka kuqhutywe ngokufanelekileyo. Amandla okufudumeza angaphakathi kwekranki kunye nomphandle wekranki kufuneka atshintshwe, oko kukuthi, amandla angaphakathi kwekranki kufuneka abe makhulu, kwaye amandla angaphandle kwekranki kufuneka abe mancinci. Obu buchwepheshe bubizwa ngokuba bubuchwephesha bokuhambisa amandla. Iikona ezijikelezileyo ze-crankshafts ezinkulu kunye ezincinci ziyacinywa. Itekhnoloji kukubonelela nge-100% yamandla xa kufudunyezwa ngaphakathi kwe crank, kunye ne 60% (okanye 70%) amandla xa kufudumeza umphandle we crank, kwaye njengokuba i crankshaft ijikeleza, i-angle iyanda (okanye iyancipha) ngesixa esithile. yonke i-15 ° Amandla.
