Summary:Existing sub-shift drive shafts used for the transmission of agricultural machinery are manufactured using the cutting process; therefore, they fail frequently owing to the heavy loads and impacts associated with intensive agricultural work. This paper presents an analytical study to improve the durability of the sub-shift drive shaft via axial hot forging with a mold. A maximum axial load of 141 tons was required to forge a ø45 × 365 mm SCM420 round bar in a ø45 (ø74) × 303 mm mold through heating at 1000℃. During forging in the axial direction, metal flow lines were well-formed along the gear-forming shape. Thus, the durability of the shaft was improved during the gear-forming process, and the weight of the raw material was reduced by 58% compared with that under the cutting process.
