Gear shaft refers to the bearing rotating parts and the rotary motion, together with the transfer torque or bending moment of mechanical parts.
According to the shape of the axis is different, the shaft can be divided into two types of crankshaft and direct axis. According to the shaft bearing, and can be divided into:
(1) the shaft, the work is under bending moment and bear torque, it is the most common mechanical shaft, such as all kinds of speed reducer of the shaft, etc.
(2) the spindle, used to support rotating parts only under bending moment and not transfer torque, some spindle rotation, such as railway vehicle shaft, etc., some of the spindle is not rotating, such as supporting the pulley shaft, etc.

(3) transmission shaft, mainly used to transfer torque and not under bending moment, such as crane mobile mechanism of long axis, the car's drive shaft, etc.
