METHOD OF HEAT TREATMENT OF SPLINED SHAFTS

摘要

FIELD: metallurgy; heat treatment of steel articles. SUBSTANCE: splined shaft manufactured from steel is subjected in succession to the following procedures: stabilizing tempering at 610-630 C, shaft cog surface normalizing and hardening of shaft cogs at heating with high-frequency currents at 170-190 C. EFFECT: avoidance of reject due to exclusion of distortion of shaft cog geometric parameters. 1 tbl
