The shaft is a cylindrical object that passes through the middle of the bearing or the middle of the wheel or the middle of the gear, but a few are square. A shaft is a mechanical part that supports a rotating part and rotates with it to transmit movement, torque or bending moment. Generally, it is a metal round rod shape, and each section can have different diameters. The rotating parts of the machine are mounted on the shaft.
Common shafts can be divided into crankshaft, straight shaft, flexible shaft, solid shaft, hollow shaft, rigid shaft, and flexible shaft (flexible shaft) according to the structural shape of the shaft.
The structural design of the shaft is an important step to determine the reasonable shape and all structural dimensions of the shaft and to design the shaft. It consists of the type, size and position of the parts installed on the shaft, the fixing method of the parts, the nature, direction, size and distribution of the load, the type and size of the bearing, the blank of the shaft, the manufacturing and assembly process, the installation and transportation, The deformation of the shaft and other factors are related.
