bronze CuZn25Al5Mn4Fe3 + Graphite plugs
The high strength copper alloy was used as the base material, and the holes were machined and filled with solid lubricant according to the working condition. High strength copper and gold provide high bearing capacity while solid lubricants can form low friction pairs. Under the condition of dry friction, we designed a layer of pre-lubrication film on the bearing surface to ensure that the solid lubricant can be transferred to the dual parts in the shortest time and form an effective solid lubrication film.
oilless bushes material is made of strong cast bronze based metal with special solid lubricants graphite embedded. The base metal with stands high load and the solid lubricants provide for self-lubrication ...
The so-called oil-free means that there is no need to add oil or
less oil. The goal of our research is to ensure that the bearing can still
perform well under such conditions and extend its service life as
much as possible. Self-lubricating bearing is the basic working
principle of solid lubricant on the surface of the bearing in the
early operational stage due to the friction of ask each other to
form a transfer film and coat the to eventually form solid
lubrication film on the grinding parts to achieve the purpose of
self lubrication, which partition the direct contact between the
workpiece and good protection of grinding extend the service life
of the bearing and artifacts.
Modern design is creating a huge demand for today's
self-lubricating bearing materials. Even in severe extreme
operating conditions and maximum load conditions maintenance free
is required. With the continuous increase of cost requirements,
enterprises have higher and higher requirements on the reliability
of equipment and plant operation. Metal self - lubricating bearings
can meet the requirements of maintenance - free and self -
lubricating in long - term service conditions, which makes it
possible to design a reliable long - term self - lubricating
system. Metal type self-lubricating bearing materials can be widely used
for rotating, swinging and linear reciprocating motion under high
load and low speed conditions, and also suitable for occasions
where traditional lubrication cannot be achieved or is prohibited,
or for long-term and stable use under special conditions such as
dust, impact load or irradiation.
