Identify self-lubricating bearings and oil bearing

What is the oil bearing? Oil bearing metal powder as main raw material, made of powder metallurgy legal sintered body, it is porous, but also in the process of manufacture can freely adjust the quantity, size, shape and distribution of pore technical advantages. Use of the porous sintered body, and make it contain dipped 10% - 40% ( Volume fraction) Lubricating oil, used in oil supply condition. Operation, the bearing temperature rise, due to the expansion coefficient is larger than the metal oil, thus automatically to the surface of the sliding lubrication bearing. Oil-retaining bearing a fuel can use a long time, often used in gas is not convenient. What is the self lubricating bearing? Self-lubricating bearings are divided into composite self-lubricating bearings, solid inlaid self-lubricating bearings, self-lubricating bearings, bimetallic materials special materials self-lubricating bearings, according to the different USES and conditions, choose different self-lubricating bearings. One of the categories of solid inlaid self-lubricating bearing ( JDB) Is a combined metal bearing characteristics and bearing characteristics of novel lubrication bearing lubrication system, the 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. Products have been widely used in metallurgical continuous casting machine, rolling equipment, mining machinery, mould and hoisting machinery, textile machinery, wind power generation, shipping, steam turbine, water turbine, injection molding machine and equipment in the production line. Wear resistance is one of the common shaft sleeve. The difference between the oil bearing and self-lubricating bearing 1, oil bearing is the combination of metal powder has 10 - 40% of the structure clearance; The inlaid self-lubricating bearing substrate is centrifugal casting; Relatively high density matrix, and the bonding strength is relatively higher oil bearing, long service life than the oil bearing. 2, oil bearing lubrication material is oil, the oil film has enough thickness, eliminates the direct contact with the friction surface of two. At this point, there is friction between liquid molecules only, so the friction coefficient is small ( f = 0。 001-0. 008). And significantly reduce the friction and wear; And inlaid self-lubricating bearing lubrication material is solid lubrication materials, even under the working condition of oil free, still can go to good lubrication effect, to ensure continuity of lubrication and sustainable, its effective lubrication life consistent with the life of the matrix; 3, the lubrication oil in the oil bearing volatile and erosion resistance, lubricating film under high temperature and high pressure is lost, can't be lubrication; Graphite copper sleeve, solid lubricant by friction, and solid lubricant in the hole or groove 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 reducing the friction and wear. With the friction, the embedded solid lubricant provided on the friction surface, to ensure the long-term operation of the friction pair when good lubrication. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
