Composite bearing impregnated related knowledge

Based on porous materials as substrates, impregnated solid lubricant, constitute a solid lubrication impregnated composite bearing, storage of solid lubricant on bearing shell interior with bearing wear continuous supply to the friction surface of solid lubricant.Typical composite bearing based on carbon graphite substrate materials, impregnation of soft metal, ptfe or inorganic matter.Impregnation method are: 1. Make dipping molten state for vacuum impregnation.2. With sclerosing liquid carrier, impregnated objects placed on them by dipping.3. Use volatile liquid as the carrier, impregnated impregnated material dispersed among them, and then make the liquid to evaporate.4. Make impregnated impregnated after vaporization.Impregnated lubrication effect not only, still can increase the strength of the base material.
Composite bearing is sometimes also called oilless bearing, copper sets, self-lubricating bearings. Oil-free bearings (SF) is a kind of both metal bearing characteristics and bearing characteristics of novel lubrication bearing lubrication system, by load matrix, and the special formula of solid lubricating materials lubrication.It has high bearing capacity, impact resistance, high temperature resistant, self-lubricating ability etc., especially suitable for overloading, low-speed, reciprocating or swing, difficult to lubrication and oil film formation, not afraid of the water and other acid erosion and erosion.Users generally reflect not only fuel-efficient inlaid bearing, energy conservation, 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, ships, steam turbine, water turbine, injection molding machine and equipment in the production line.
