  Shaft (shaft) is in the middle of bearing wear or gear wheel intermediate or intermediate cylindrical object, but a small part of the square. The shaft is rotatably supported parts and therewith to transmit rotary motion, torque or moment of mechanical parts. Generally circular rod-shaped metal can have different diameters paragraphs. Rotary movement of the machine parts installed on the shaft. Priority to forging blank axis, followed by round; large size or complex structures may consider cast or ductile iron. For example, with ductile iron crankshaft, camshaft, with low cost, better vibration absorption, low sensitivity to stress concentration, intensity, etc. better. Mechanical model is the beam axis, the majority is to be rotated, so the stress is generally symmetrical loop. The possible failure modes are: fatigue fracture, overload fracture, elastic deformation too big. Axle with hub usually install some parts, so most should be made stepped shaft axis, cutting volume.
