The gear shaft is the mechanical parts to support turn parts and the turning together with it to transfer movement and it generally is metal round bar, having different diameter. According to the axis of the different shapes, the shaft includes crankshaft and direct axis. According toits loading conditions, the shaft can be divided into rotors, mandrel and transmission shaft. When rotors isunder bending moment and under twist, when it is working, and is most main mechanical shaft, such as all kinds of gear reducer shafts. Mandrels are used to support turn parts, it is only under bending moment and not under transfer torque. Some mandrels rotate, such as shaft of railway vehicles, but some mandrels don't rotate, such as supporting the pulley shaft, etc. Transmission shaft is mainly used to transfer torque and not under bending moment, such as crane mobile mechanism of long axis, the car's drive shaft, etc.
Its material is the carbon steel or alloy steel, but nodular cast iron or alloy cast iron is also used. The ability generally depends on intensity and rigidity, when high speed, depends on the vibration stability.
