Shaft Machining Structural classification

Structural classification
The structural design of the shaft is an important step for the design of the shaft to determine the reasonable shape of the shaft and the overall size of the shaft. It consists of the type, size, and position of the mounting parts on the shaft, the fixing of the parts, the nature, direction, size, and distribution of the load. The type and size of the bearing, shaft blanks, manufacturing and assembly processes, installation and transport, and the shaft deformation and other factors. The designer can design according to the specific requirements of the shaft. If necessary, several options can be done for comparison. In order to select the design scheme, the following is the general shaft structure design principle:
1, save materials, reduce weight, as far as possible the use of equal-strength dimensions or large cross-sectional coefficient of the cross-sectional shape;
2, the shaft part is easy to pinpoint, solid, assembly, disassembly and adjustment;
3, the structure of various measures to reduce stress concentration and increase in strength;
4, to facilitate manufacturing and to ensure accuracy.
5. The nature, size, direction and distribution of the load;
6, shaft machining process and assembly methods.
7. The shaft and the parts mounted on the shaft must have an accurate working position;
