The Process and Princlple of Self-Lubricating Bearings
Technology and Principles:
Special Production Process: Due to the special requirements of the production process,
some of the key equipment of industrial and mining enterprises in extermely harsh conditions to
run. Due to heavy equipment, high ambient temperature, dust or air containing acid corrosion gas
CO, SO2, etc, the equipment lubrication to bring a lot of problems, friction and wear serious, so
far, most of the domestic enterprises still use the traditional oil, grease lubrication range,
prone to bearing and other friction vice bites or killed, causing serious parts wear and damage,
often lead to equipment outrage. In order to produce continuous 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. Severely restricting the increase in
producticity, 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 lunbricating 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 sloved 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.
Key Technical Principles:
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 mateal
subatrates bear the vast majority of the load. The solid lubrication film, which is lubricated
and firmly adhered and uniformly covered on the friction surface, is geatly 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-termoperation of the friction on the good lubrication.
