Motor shaft/special-shaped shaft/printer shaft/new energy motor shaft/CNC centering machine automatic lathe
Motor shaft:
Basic definition: The motor shaft is a cylindrical component protruding from the motor and its housing. It is the main support and connector of the armature part of the motor. It is also the output component of the power generated by the motor. Its function is to convert the energy of the motor into Mechanical energy to drive other equipment to operate.
Material requirements: Usually made of high-quality alloy steel, carbon steel and other materials, it has high strength and stiffness, and can withstand various mechanical forces and moments generated when the motor is running, such as the gravity of the rotor component itself and the eccentricity of the rotor. One-way magnetic pulling force, centrifugal force of unbalanced weight, and load torsional moment exerted on the shaft by transmission machinery at the shaft extension end, etc.
Technical requirements: The motor shaft needs to have good straightness to ensure that the motor does not vibrate during normal operation; the surface roughness must be moderate. For sliding bearings, excessive surface roughness will destroy the oil film on the contact surface and increase bearing wear. If it is too low, intermolecular friction will form between the shaft and the bearing; if a bearing is installed on the shaft, the surface hardness of the shaft needs to be controlled, generally not higher than HV450 (different bearing types may have different requirements for the surface hardness of the shaft) ).
Special-shaped shaft:
Basic definition: Special-shaped shafts are one type of shaft parts, which are different from common shafts with more regular shapes such as smooth shafts and stepped shafts. Its shape is designed according to specific functional requirements and usage scenarios, and there is no fixed standard shape. Printer axis:
Basic functions: The printer shaft is an important part of the printer and mainly plays the role of transporting paper. The printer shaft includes a main shaft. The left and right ends of the main shaft are connected to a rotating shaft. The power part drives the rotating shaft to rotate, and the rotating shaft drives the main shaft to rotate. The rubber part on the outer wall of the printer shaft exerts friction on the paper, causing the paper to move in the required direction.
Structural features: In order to facilitate installation and maintenance, most current printer shafts adopt a combined structure, which is composed of a shaft core, a plug-in plate, a sleeve, an anti-slip sleeve and other components, which 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 needs to have a certain degree of roughness and wear resistance.
Material selection: Generally made of steel, aluminum alloy and other materials, it has high strength and rigidity and can withstand the pressure and friction when the printer is working.
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. The new energy motor shaft is one of the core components of the new energy motor and has an important impact on the performance and reliability of the new energy vehicle.
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 new energy vehicles for motors. For example, when rotating at high speed, the new energy motor shaft needs to be able to withstand greater centrifugal force and torque, while 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 alloys, carbon fiber composite materials, etc.
Widely used in automobiles, machinery manufacturing, aerospace and other fields.
For example, in automobile steering systems, special-shaped shafts can achieve special steering functions; in some complex mechanical devices, special-shaped shafts can meet special connection and transmission requirements between different components.
