1) Description of Copper Bushing
Copper bushings are tubular components primarily made from copper alloys. Common copper alloy materials include tin bronze
and aluminum bronze. Leveraging the excellent physical and chemical properties of copper alloys, they serve functions
such as friction reduction, wear resistance, and support in mechanical components. They are widely used mechanical parts.
2) Feature and Advantage of Copper Bushing
a) Good Wear Resistance: Copper alloys have moderate hardness and self - lubricating properties.
During relative motion with the shaft, they can effectively reduce friction and wear, thereby extending the service life of equipment.
For instance, when the tin content in tin bronze is high, it can form a hard and wear - resistant structure,
significantly enhancing its wear - resistant performance.
b) Strong Corrosion Resistance: Copper exhibits good corrosion resistance in the atmosphere and fresh water.
Some copper alloys, such as aluminum bronze, can maintain stable performance even in highly corrosive environments
like seawater, making them suitable for various complex working conditions.
c) Excellent Thermal Conductivity: Copper has extremely good thermal conductivity. During the operation of machinery,
copper bushings can quickly dissipate the heat generated by friction, preventing component damage caused by local overheating
and ensuring the stable operation of the equipment.
3) Working Principle of Copper Bushing
Copper bushings are installed in the holes of mechanical components and used in conjunction with shafts.
When the shaft rotates, relying on their good wear - resistance and self - lubricating properties, copper bushings form
a relatively stable sliding friction pair between the shaft and the hole. Meanwhile, their thermal conductivity helps dissipate heat
in a timely manner, reducing wear and deformation caused by the accumulation of frictional heat,
and ensuring the normal operation and positioning accuracy of the shaft.
4) Application of Copper Bushing
Copper bushings are commonly used in the bearing parts of fluid conveying equipment such as water pumps and compressors,
as well as in the screw - nut mechanisms of machine tools. In water pumps, copper bushings can effectively resist the corrosion
and wear caused by water flow. In the screw - nut mechanisms of machine tools, they can ensure the smooth movement and accuracy of the screw.
