JDB oil-free bearing profile

Metal-based inlaid solid self-lubricating bearings (referred to as JDB) is a new metal bearing features and self-lubricating bearings features a novel lubricating bearings, the metal substrate to withstand the load, a special formula of solid lubricating material lubrication. It has a high load capacity, impact resistance, high temperature, self-lubricating ability and other characteristics, especially for heavy load, low speed, reciprocating or swinging difficult to lubricate and the formation of oil film occasions, are not afraid of water erosion and other acid erosion And wash. The majority of users generally reflect inlaid bearings not only fuel-efficient, energy-saving, but also their working life is longer than ordinary plain bearings. At present products have been widely used in metallurgy continuous casting machine, rolling just equipment, mining machinery, ships, steam turbines, turbines, injection molding machines and equipment in the production line.
Special production process
Due to the special requirements of the production process, some key industrial and mining equipment in extremely harsh conditions to run. Due to heavy equipment, high ambient temperature, large dust or air with acidic corrosive gases CO, SO2, the lubrication of the equipment to bring many problems, serious friction and wear, so far, the majority of domestic enterprises still use the traditional oil, Grease lubrication, and in fact these mining conditions have exceeded the oil, grease lubrication range, prone to bite bearings and other friction or biting, causing serious wear and tear parts damage, often leading to equipment outage. In order to produce continuous operation, in addition to the original design requires the installation of more than one equipment rotation, but also put a lot of maintenance personnel. This has seriously hampered the improvement of productivity and the enormous spare parts and energy consumption that have become an important obstacle to the development of production. Automobile manufacturing, cement production, petrochemical and other companies have proposed to provide complex conditions under the conditions of special lubricants requirements. To this end, the mosaic self-lubricating composite materials research, material formulation and preparation process to highlight its own characteristics, material properties have reached the international advanced level, for enterprises to solve the lubrication under special conditions, and brought a clear Economic and social benefits. However, due to a variety of reasons more domestic enterprises have not yet adopted, the above situation still exists.
2 key technical principles
Inlaid self-lubricating composite material is a new type of anti-extreme pressure solid lubricating material composed of a metal substrate and a solid lubricant paste embedded in a hole or a groove of the substrate. In the friction process, the metal substrate bear most of the load. The friction, hole or groove of the solid lubricant to the friction surface transfer or reverse transfer, the friction surface to form a well-lubricated, solid adhesion and uniform coverage of the solid transfer film, greatly reducing the friction and wear. As friction progresses, the embedded solid lubricant is continuously supplied to the friction surface to ensure good lubrication of the friction pair during long-term operation.
