Shaft parts in machine products are general purpose parts and are very common in applications. The working capacity and quality of the machine are largely related to the shaft. Once the shaft fails, it may have serious consequences. The shaft is one of the important parts that make up the mechanical structure. The machining of shaft parts is based on Titanium, which is the main part of the shafting parts and a key component for supporting the parts on the shaft, transmitting motion and power. In order to ensure that the parts mounted on the shaft can be correctly positioned and fixed to meet the requirements of machining and assembly of the shaft, the shape and structural dimensions of the various parts of the shaft must be reasonably determined, that is, the structural design is performed.
I. Overview of the processing of shaft parts
The shaft is a cylindrical object that is worn in the middle of the bearing or in the middle of the wheel or in the middle of the gear, but a few are square. A shaft is a mechanical part that supports a rotating part and rotates therewith to transmit motion, torque or bending moments. Generally, it is a metal rod shape, and each segment can have a different diameter. The parts of the machine that make a swivel motion are mounted on the shaft.
According to the shape of the axis, the shaft can be divided into two types: the crankshaft and the straight shaft. According to the bearing condition of the shaft, it can be divided into: shaft, mandrel and drive shaft. The structural design of the shaft is an important step in the design of the shaft to determine the proper shape of the shaft and the overall structural dimensions. It consists of the type, size and position of the part mounted on the shaft, the way the part is fixed, 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 transport, the shaft Related to factors such as deformation
Therefore, the designer can design according to the specific requirements of the shaft parts, and if necessary, several solutions can be compared to select the best design.
