The function and structural characteristics of the shaft forging
1.Function: Supporting transmission parts (gears, pulleys, etc.), transmission torque, receiving load, and ensuring that the workpiece or tool mounted on the spindle has a certain reversal accuracy.
2.Classification: The shaft forgings can be divided into four categories according to their structural shape, which can be divided into optical axis, stepped shaft, hollow shaft and special-shaped shaft (including crankshaft, camshaft and eccentric shaft).
1) optical axis;
2) hollow shaft;
3) half shaft;
4) stepped shaft;
5) spline shaft;
6) cross shaft;
7) eccentric shaft;
If divided according to the length and diameter of the shaft, it can be divided into two types: rigid shaft and flexible shaft.
3.Appearance features: outer circle, inner hole, cone, thread, spline, transverse hole.
