Intro
Converted into the rotating mo-tion of the crankshaft to be con-nected to the linear energy of re-ciprocating piston engine parts
Material
Endure compressive strength, tensile, and bending
Need strength, stiffness and reducing weight
Used chrome-molybden steel, through the description of the above
Manufacturing Process
Raw material Impression-die forging Annealing Rolling(Flat, Structural shape) Machining Heat treatment Grinding
Raw Material
Steel(Carbon 0.25~0.35%)
Chrome : 0.8~1.1%
Molybden : 0.15~0.25%
Manganese : 0.4~0.6%
Impression-die forging
Annealing & Rolling
Flat rolling Structural shape rolling
Machining & Heat treatment
Machining & Grinding
Reduce surface rough-ness
Increase accuracy
Heat treatment(Tempering)
Quenching is increase strength but occur brittleness
Tempering over 200˚Creduce brittleness
