Motor Shaft/Shaped Shaft/Printer Shaft/New Energy Motor Shaft/Automatic Lathe for CNC Centering Machine

タイトルまたは説明

Motor shaft:
Basic definition: the motor shaft is a cylindrical part that extends from the motor and its shell, it is the main support and connection part of the armature part in the motor, and it is also the output part of the power generated by the motor, its role is to convert the energy of the motor into mechanical energy to drive other equipment to run.
Material requirements: usually made of high-quality alloy steel, carbon steel and other materials, with high strength and stiffness, able to withstand a variety of mechanical forces and moments generated by the operation of the motor, such as the rotor components of their own gravity, rotor eccentricity caused by the one-way magnetic pull, the centrifugal force of the weight of the unbalance, and the end of the axle extension by the transmission of mechanical load torque acted on the shaft and so on.
Technical requirements: the motor shaft needs to have a good straightness to ensure that the motor does not produce vibration during normal operation; surface roughness should be moderate, for sliding bearings, too high surface roughness will destroy the contact surface oil film, increase bearing wear, too low will make the shaft and the formation of intermolecular friction between the bearings; if the shaft is mounted on the bearings, but also need to control the surface hardness of the shaft, generally not higher than HV**0 (different bearing) types may have different requirements on the surface hardness of the shaft).
Shaped shafts:
Basic Definition: Shaped shafts are one type of shaft parts, distinguishing them from common shafts with more regular shapes such as bare shafts and stepped shafts. Its shape is designed according to specific functional requirements and use scenarios, and there is no fixed standard shape. Printer shaft:
Basic function: the printer shaft is an important part of the printer, mainly play a role in the transmission of paper. Printer shaft contains the spindle, spindle left and right ends of each articulated with a spindle, the power part of the spindle to drive the rotation of the spindle, the spindle and then drive the spindle to rotate, the printer shaft of the outer wall of the rubber part of the paper to exert friction, so that the paper in accordance with the direction of the need to move.
Structural features: In order to facilitate the installation and maintenance, the printer shaft is now more of a combined structure, composed of core, insert, sleeve, anti-slip sleeve and other components, can be easily disassembled and assembled. At the same time, in order to ensure the stability and accuracy of paper transmission, the surface of the printer shaft usually need to have a certain degree of roughness and wear resistance.
Material selection: generally made of steel, aluminum alloy and other materials, with high strength and stiffness, able to withstand the pressure and friction of the printer work.
New energy motor shaft:
Application background: With the rapid development of new energy vehicles and other industries, the demand for new energy motor shafts is increasing. New energy motor shaft is one of the core components of new energy motor, which has an important impact on the performance and reliability of new energy vehicles.
Technical features: Compared with traditional motor shafts, new energy motor shafts need to have higher precision and strength to meet the high-performance requirements of motors for new energy vehicles. For example, when rotating at high speeds, new energy motor shafts need to be able to withstand greater centrifugal force and torque, while also maintaining good dynamic balance performance to reduce motor vibration and noise.
Material innovation: In order to reduce weight and improve performance, new energy motor shafts may use some new materials, such as high-strength aluminum alloy, carbon fiber composite materials.
