Axis (shaft) is in the middle of the bearing or gear wheel in the middle or in the middle of the cylindrical objects, but there are also a few is square. Shaft is supporting and rotating parts with rotary to pass motion, torque or bending moment of mechanical parts. Generally for metal round rods, paragraphs can have different diameters. For rotary movement of the parts in the machine is installed on the shaft.

  Common shaft have crankshaft, straight shaft and flexible shaft three kinds.

 Direct axis can be divided into:

1. axis, both under bending moment and torque under at work, is the most common mechanical axis, such as various of the reducer shaft, etc.

2. the mandrel, which is used to support rotating components were not only under bending moment and torque, some of the spindle rotation, such as the axis of the railway vehicle, some of the spindle is not turning, such as the shaft supporting pulley and so on.

3. the shaft, is mainly used to transfer torque and not under bending moment, such as to the long axis of the mobile crane, automobile drive shaft, etc. Shaft materials mainly adopts carbon steel or alloy steel, ductile iron or alloy cast iron may be adopted. Shaft work ability generally depends on the strength and stiffness, high speed also depends on the vibration stability.
