SOBW SOBWN oilless washer, cast bronze wear washer manufacturer

Selection and Characteristics of Oil - free Self - lubricating Bearing in Casting Oil-free self-lubricating bearings in the casting of the selection and its characteristics: Oil-free self-lubricating bearings In order to solve the mechanical equipment in high temperature, low speed, heavy load, dust, water shower and shock vibration of the lubrication problem, the choice of oil-free self-lubricating bearings. 1, SOBW SOBWN oilless washer, cast bronze wear washer the structure of self-lubricating bearings in the bearing base metal friction surface bimetallic bearings on the orderly development of the appropriate size of the hole, and embedded molybdenum disulfide, graphite and other linear bearings made of self-lubricating blocks embedded in the metal sleeve , Made of composite bearings, solid lubricant friction area of ??25-65%. Automotive bearing model query software bearing the world Solid self-lubricating block can work at 280 ℃ high temperature. But because of its low mechanical strength, carrying capacity of copper bushing is weak, easy to produce deformation, it is embedded in the metal hole slot can inhibit this shortcoming, forming a metal part from the bearing role, self-lubricating block from the lubrication effect. Automotive bearing model query software bearing the world The self-lubricating bearing lubrication mechanism is in the shaft and sleeve sliding friction process, a part of the molecular self-lubricating material transferred to the axis of the metal surface, filling the small uneven surface, and the formation of a layer of relatively stable solid lubricating film , Resulting in lubrication between the solid lubricating film, to prevent the shaft and sleeve adhesion wear. Automotive bearing model query software bearing the world This combination of rationality combines the complementary advantages of copper alloys and non-metallic wear-reducing materials, and is particularly suitable for oil-free, high-temperature, high-load, low-speed, anti-fouling, corrosion protection, strong radiation environments. In water or other solution infiltration and can not add lubricating grease under the special conditions of use. Automotive bearing model query software bearing the world 2, self-lubricating block accounting for the area than the surface area of ??the number of self-lubricating blocks and the speed of operation, bearing strength, low speed; compression strength, metal occupied area should be larger. Automotive bearing model query software bearing the world Such as grasping the spindle car traveling wheel bearing self-lubricating block accounted for about 25% of the area, pull spindle spindle bearing lubrication should be sufficient, the compressive strength is not large, self-lubricating block accounted for about 65% of the area.JDB Graphite Lubricating Bushing model query software bearing the world 3, the technical requirements of bushings Bushing should be made of copper alloy, bushings have a higher hardness, generally required to heat treatment, the hardness of not less than HRC45. Bearing enterprise navigation 4, self-lubricating block of the geometry and mosaic requirements. Self-lubricating block shapes are cylindrical and rectangular, self-lubricating according to the size of the area can be used cylindrical, and vice versa can be rectangular. No matter what shape must be firmly embedded in order to prevent loss in operation. Bearing enterprise navigation 5, the liner with the shaft with the gap value of self-lubricating block of linear expansion coefficient of about 10 times the steel. Industrial bearings enterprise navigation In order to adapt to the bearing temperature change, the gap between the shaft and the bushing is increased from 0.45 to 0.5MM by the original four-step dynamic fitting (D4 / DC4) 0.032 ~ 0.15MM. Bearing enterprise navigation Self-lubricating block in the friction side of the protruding bushing metal 0.2 ~ 0.4MM. This will be in the initial run-in period of the bearing is fully lubricated to reduce the power consumption of the drag power. Bearing enterprise navigation 6, the advantages of oil-free self-lubricating bearings
