METHOD FOR HARDENING CRANKSHAFTS OF INTERNAL COMBUSTION ENGINES Russian patent published in 1994 - IPC

Abstract RU 2019382 C1

FIELD: mechanical engineering. SUBSTANCE: method involves induction hardening of main and connecting rod journals and fillets on transition of journals into crank webs and subsequent plastic deformation of oil holes in main and connecting rod journals by hydrostatic pressure whose value exceeds the yield point of crankshaft material. EFFECT: higher efficiency. 2 dwg
