Intro

Converted into the rotating mo-tion of the crankshaft to be con-nected to the linear energy of re-ciprocating piston engine parts

Page 3: Converted into the rotating motion of the crankshaft to be connected to the linear energy of reciprocating 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

Raw Material

Steel(Carbon 0.25~0.35%)

Chrome : 0.8~1.1%

Molybden : 0.15~0.25%

Manganese : 0.4~0.6%

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
