1) Description of Copper Bushing
In mechanical systems, copper bushings serve as crucial auxiliary
mechanical components, primarily used to reduce friction
and wear between shafts and holes, providing support, positioning,
and guiding functions. Through precise fitting with the shaft,
they ensure the normal operation of mechanical components and
maintain their accuracy.
2) Feature and Advantage of Copper Bushing
a) High - precision Fitting: Copper bushings can be precisely machined
to achieve high - precision clearance or interference fits
with the shaft, ensuring the stability and positioning accuracy of
the shaft during rotation and meeting the motion accuracy
requirements of mechanical systems.
b) Vibration Damping and Buffering: During the operation of machinery,
copper bushings can absorb the vibrations and impacts of the shaft,
reducing noise and vibrations during equipment operation, thereby
improving the operational comfort and reliability of the equipment.
c) Easy Installation and Maintenance: Copper bushings feature a simple
structure, making them easy to install and disassemble.
When wear or damage occurs, only the copper bushing needs to be
replaced, eliminating the need for a complete overhaul of the
mechanical component.
This reduces equipment maintenance costs and downtime.
3) Working Principle of Copper Bushing
Copper bushings are installed on fixed mechanical components
through interference fits or with the help of fasteners,
and the shaft is inserted into the inner hole of the copper
bushing. When the machinery is in operation, the copper bushing,
on the one hand, provides support and guidance for the shaft,
ensuring the shaft's motion trajectory; on the other hand,
through its elastic deformation and surface properties, it buffers
the external impacts and vibrations on the shaft,
reducing the impact on other components of the mechanical system
and maintaining the stable operation of the system.
4) Application of Copper Bushing
Widely used in areas such as the crankshafts and connecting rods of
automotive engines, hydraulic cylinders in the hydraulic systems of
construction machinery, and the transmission mechanisms of printing
machinery. In automotive engines, copper bushings
ensure the smooth operation of the crankshaft and connecting rods;
in the hydraulic cylinders of construction machinery,
they ensure the linearity and sealing of piston movement.
