The Product Background, Production Technology And Technical Principles Of Copper Graphite Bearing
Product Background:
Solid inlaid copper graphite bearings (referred to as JDB) is a combination of metal bearing
characteristics and oilless bearing characteristics of the new lubricating bearings, from the metal
matrix to withstand the load, the special formula of solid lubricating material from the
lubrication. It has the characteristics of high carrying capacity, impact resistance, high
temperature resistance and high self-lubricating ability. It is especially suitable for occasions
such as heavy load, low speed, reciprocating or swinging and so difficult to lubricate and form oil
film, and is not afraid of water erosion and other acid scouring. The current products have been
widely used in metallurgical caster, rolling equipment, mining machinery, ships, steam turbines,
turbines, injection molding machines and equipment production lines.
Production Process:
Due to the special requirements of the production process, some of the key equipment of
industrial and mining enterprises in extremely harsh conditions to run. Due to heavy equipment, high
ambient temperature, dust or air containing CO2, SO2 and other acidic corrosive gases, to the lubrication of the equipment to bring a lot of problems, friction and wear serious, so far, most
of the domestic enterprises still use the traditional oil, lubrication, and in fact these conditions
are beyond the oil, grease lubrication range, prone to bearing and other friction vice bites or
killed, causing serious parts wear and damage, often lead to equipment outage.
In order to produce continious operation, in addition to the original design requirements for
the installation of multiple equipment gear repair, but also to invest a large number of maintenance
personnel, seriously limiting the productivity increase, spare parts and energy consumption is
great, has become an important obstacle to the development of production. Automobile manufacturing,
cement production, petrochemical and other enterprises have proposed to provide complex conditions
of special lubricating material requirements. To this end, the research on mosaic self-lubricating
composites highlights its own characteristics in material formulation and preparation process. The
material properties have reached the international advanced level, which has solved the problem of
lubrication under special working conditions and brought obvious Economic and social benefits. But
because of a variety of reasons more domestic enterprises have not yet adopted, the above situation
still exists.
Technical Principle:
The composite material used in the mosaic self-lubricating bearing is a new type of anti-
extreme pressure solid lubricating material consisting of a metal substrate and a solid lubricant
paste embedded in the hole or groove of the substrate. In the process of friction metal substrates
bear the vast majority of the load. The solid lubricant film, which is lubricated and firmly adhered
and uniformly covered on the friction surface, is greatly reduced in friction and wear by the solid
lubricant in the friction, hole or groove to the friction surface. With the friction, the embedded
solid lubricant is constantly provided on the friction surface, ensuring long-term operation of the
friction on the good lubrication.
