By load matrix, and the base metal Mosaic solid self-lubricating bearing (JDB) characteristics of a combined metal bearing and lubrication bearing characteristics of novel lubrication bearing.Special formula of solid lubricating materials lubrication.With high bearing capacity, impact resistance, high temperature resistant, self-lubricating ability etc., especially suitable for overload, low speed, reciprocating swing or difficult to lubrication and oil film formation, not afraid of the water and other acid erosion and erosion.Users generally reflect the inlaid bearing not only saving, energy saving, and its working life is longer than ordinary sliding bearing.Current products have been widely used in metallurgical continuous casting machine, rolling just equipment, mining machinery, shipping, steam turbine, water turbine, injection molding machine and equipment in the production line.
1, industrial and mining enterprises, some of the key equipment to run in very bad condition.Due to the heavy equipment, high temperature, due to the special requirements of production process.Dust or air containing acid corrosion in gas CO, SO2, etc., bring many problems of equipment lubrication, friction and wear is serious, so far, most of the domestic enterprises is still using the traditional oil, grease, and the fact that the industrial and mining condition is beyond the scope of oil, grease, easily happened bearing and other friction pair of bite or killed, cause severe parts wear and damage, frequently lead to equipment shutdown.To produce continuous operation, in addition to many sets of equipment required in the original design round outside, still must invest a lot of maintenance personnel.Severely limits the productivity, spare parts and the energy consumption greatly, has become the important obstacle of developing production.Automotive, cement production, and petrochemical enterprises are put forward to provide the special lubricating materials under complex working condition requirements.To this end, the inlay type of self-lubricating composite materials research, formulation and preparation technology of materials highlight its own characteristics, material performance has reached the international advanced level, for the enterprise can solve the problem of lubrication under special working conditions, and has brought obvious economic and social benefits.But due to a variety of reasons more domestic enterprises has not been adopted, the situation is still there
2, the metal substrate and the embedded holes or slots in the solid lubricant paste.Friction in the process of the metal substrate for the most part bear the load.The friction, the key technical principles: inlay type of self-lubricating composite is a new kind of extreme pressure of solid lubricating materials.Holes or slots in the solid lubricant to the friction surface transfer or negative transfer, the friction surface to form a good lubrication, strong adhesion and uniform coverage of solid transfer film, greatly reduce the friction and wear.With friction, the embedded solid lubricant from time to time, provide the friction surface to ensure the temporary runtime for good lubrication of the friction pair.
