Base metal inlaid solid self-lubricating bearings (hereinafter referred to JDB) is a characteristic of both metal bearings and self-lubricating bearing characteristics of novel lubricating bearings, a metal matrix load bearing, solid lubricant specially formulated for lubrication. It has a high carrying capacity, impact resistance, high temperature resistant, self-lubricating ability and other characteristics, especially suitable for heavy, low-speed, swinging back and forth, or the like to form a film of lubrication and difficult situations, it is not afraid to flush and other acid erosion and erosion. The majority of users generally reflect the mosaic bearing not only fuel-efficient, energy-saving, and its working life longer than ordinary plain bearings. The products have been widely used in metallurgy continuous casting machine, just rolling equipment, mining machinery, ships, steam turbine, turbine, injection molding machines and equipment production pipeline. 1. Due to the special production requirements, some key industrial and mining equipment run extremely harsh conditions. Because of heavy equipment, the ambient temperature is high, dusty air with acidic or corrosive gases CO, SO2, etc., lubrication equipment to bring a lot of problems, friction and wear serious, far, most domestic companies still follow the traditional above-mentioned oil, greased, and the fact that these conditions are beyond the mining of oil, grease lubricated range, prone to friction bearings and other bite or killed, causing severe wear and tear parts, regularly cause equipment outages. For the production of continuous operation, in addition to the original design requires the installation of multiple units wheel repair, it must also invest a lot of maintenance personnel. Seriously improve the productivity, spare parts and energy consumption greatly, it has become an important obstacle to the development of production. Automobile manufacturing, cement production, petrochemicals and other companies have made special lubricating material requirements provided under complicated working conditions. To this end, mosaic self-lubricating composite material, the material in the formulation and preparation process highlight its own characteristics, material properties has reached the international advanced level, for enterprises to solve the problem of the special conditions of lubrication, and has brought significant economic and social benefits. However, due to various reasons more domestic enterprises have not yet adopted the above condition still exists. 2. The key technical principles mosaic self-lubricating composite material is a novel anti-extreme pressure solid lubricant, a metal substrate and embedding substrate hole or slot solid lubricant paste composition. Metal substrate during rubbing bear most of the load. Transfer through friction, holes or slots solid lubricant to the friction surface or reverse shift, formed in the friction surface oiled, firmly attached and uniform coverage of solid transfer film to significantly reduce friction and wear. With friction were embedded solid lubricant continue to provide the friction surface to ensure good lubrication of the friction of the long run.
