On the processing technology of shaft core

The function, structural characteristics and technical requirements of the shaft core parts: The shaft core parts are one of the typical parts often encountered in the machine. It is mainly used to support transmission parts, transmit torque and bear load. The shaft section is a body of revolution section, the length of which is greater than the diameter, usually consisting of the outer cylindrical surface of the concentric shaft, the conical surface, the inner bore and the inner thread, and the corresponding end face. According to different structural shapes, shaft parts can be divided into optical axis, stepped shaft, hollow shaft and crankshaft.

Causes and treatment of motor shaft fracture

(1) The main reason for the fracture of the motor shaft ① The motor shaft vibrates violently. Even if it runs under overload, the dynamic load will increase, which will cause the shaft fatigue and fracture. ②The step difference formed due to the different shaft diameters causes the cross section of the shaft to change suddenly, or there is a keyway on the shaft, which causes the stress to concentrate on the shaft and break.

Heat treatment method for motor shaft parts

(1) Quenching and tempering heat treatment: 45 steel is a medium carbon structural steel with good cold and hot processing properties, good mechanical properties, low price and a wide range of sources. Its biggest disadvantage is that it has low hardenability and is not suitable for motor shaft workpieces with high cross-sectional dimensions and requirements.

Application and Function of Axle Core

The shaft core is also called precision shaft or micro shaft. The main materials we use are carbon steel, stainless steel, copper, aluminum, etc. The surface can be galvanized, nickel plated, carburized and other treatments according to customer needs. The shaft core is usually a non-standard part, we can customize the processing according to customer samples or drawings.

Three and precision shaft on the shaft core

The standard shaft core is a mechanical part that connects rotating parts. In the current mechanical field, parts are connected to each other to ensure the normal operation of large equipment. The structure of the fixed shaft core is different, the force is different, the gear fit is also different, and the installation method is also different.
