Self-lubricating principle of inlaid bearing graphite rods and sliders
2019-02-13
Self-lubricating bearings and sliders embedded with solid lubricants, under the action of friction heat, expand the solid lubricant, automatically transfer to the friction surface, form a layer of lubricating film to prevent metal-to-metal contact, thereby reducing friction factor and wear, and improve The bearing capacity of the bearing. Metal skeleton, according to the needs of gear pump bearing users, bronze, cast iron, cast steel, stainless steel, non-metallic skeleton can be used bakelite, phenolic plastic, nylon and so on.

Second, the characteristics of inlaid bearings and sliders: Self-lubricating bearings and sliders with solid lubricants are made of 10 kinds of lubricating materials with excellent lubricating properties and special lengths, some of which can accept under heavy load. The bearing pressure is on the 2 um thick JDB solid inlaid bearing film, the friction speed of 40m per second can withstand the contact stress of 2800Mpa; some components, low shear force between molecules, low adhesion is easy to form Molecular slip surface, only in the lubrication layer of 2.5um thickness, there are about 40,000 JDB bronze inlaid bearing slip surface, which plays a key role in the lubrication performance of solid lubricant; some components are at 399 °C high temperature, The friction factor is normal; some components have good lubrication properties in normal temperature, normal load, high friction speed, vacuum, and atmosphere. In short, self-lubricating solid lubricants with inlaid bearings and sliders can be adapted to the friction conditions of various working conditions. The friction factor is mostly between 0.006 and 0.09.
Third, the use of inlaid bearings, sliders: Inlaid bearings and sliders are embedded in the skeleton by solid lubricants, self-lubricating friction operation, ideally solve the pollution problems caused by liquid lubricants in the lubrication process, so Widely used in food machinery, pharmaceutical machinery and other non-polluting environments. The solid lubricant used in the inlaid bearing and the slider has the characteristics of large load bearing, so it is very suitable for the heavy-duty, low-speed, high-temperature, water vapor and other corrosion conditions and the inconvenient and frequently lubricated working conditions of the oil film. Used in mining, metallurgy, petroleum, geology, chemical, paper, bridges, hydraulic hubs, ships, aerospace and other industrial sectors. The most outstanding results, such as steel ladle cranes and 1150 roughing mills, are 6-8 times longer than the original bearing pads. Various rolling mills, shearing machines, cold bed sliders (pipe pullers), pharmaceutical machines, twisting pots, rubber mill bearings, floating crane bearings, textile mill dryers, non-ferrous metal rolling mills, steel plates for heavy-duty vehicles The pin bushing, the twisting mixer of the chemical plant, the roller bearing of the coal mine conveyor, the inner sleeve of the drilling machine deep rod pump, the protective drill sleeve and the guiding bushings, sliders and cam discs on various equipments are all very obvious. .
Fourth, the use of inlaid bearings, sliders:
(1) Inlaid bearings and sliders have been coated with a special layer of grease on the friction surface before leaving the factory. Do not soil the friction table during installation. Do not wipe off the grease! ! ! If it is rubbed off, please replace it with molybdenum disulfide lithium grease, but it must be run at low speed for a period of time before the test run, in order to operate normally. When using heavy load equipment, you must purchase special grease repaint from the seller. .
(2) When installing the inlaid bearing, it must ensure a certain sliding clearance to prevent jamming and damage the bearing and the machine.
(3) When installing the inlaid bearing, it should ensure that the shaft diameter with which it is rubbed has a good cylindricity, so that it has sufficient contact area with the bearing, otherwise it will seriously affect the service life of the bearing or damage immediately.
Five, inlaid bearings, sliders factory specifications: This product is widely used in many industries, so it is difficult to unify specifications.
