METHOD FOR SURFACE HARDENING OF CYLINDRICAL SURFACES OF CRANK SHAFTS BY SHOTS Russian patent published in 1998 - IPC

Abstract RU 2112638 C1

FIELD: processes for surface hardening of journals of crank shafts, distributing shafts and pins of internal combustion engines. SUBSTANCE: holder of two ring halves is arranged around journal of crank shaft. Holder is provided with jets for supplying liquid or gaseous shot-loaded energy carrier. Process is realized when crank shaft is fixed. EFFECT: elimination of wear of edges of journals, uniform hardening. 3 cl, 2 dwg
