In order to deal with mechanical equipment in the high temperature, low speed, heavy load, dust, water shower and shock oscillation of the smooth question, the choice of oil-free self-lubricating bearings.
1, the bearing structure Since the smooth bearing is the bearing matrix on the metal surface of the development of the appropriate size and proper placement of the hole, and embedded in molybdenum disulfide, graphite and other composite from the smooth block inlaid in metal sets, made Of the composite bearings, solid smoothing agent friction area of ​​25-65%. Solid from the light block at 280 ℃ high temperature normal operation. But because of its low mechanical strength, bearing capacity can be weak, prone to deformation, it will be embedded in the metal hole slot can inhibit this defect, forming a metal part from the bearing effect, since the smooth block from the smooth effect. The smooth mechanism of this self-smooth bearing is in the course of the sliding conflict between the shaft and the sleeve of the tin bronze bushing, which is transferred from the part of the smoothing material to the metal surface of the shaft, filling the small uneven surface and forming a layer of more stable Of the solid smooth film, the formation of solid smooth film between the grinding, to avoid the shaft and sleeve adhesion wear. This combination of rationality summarizes the complementary strengths of copper alloys and nonmetallic materials, which are particularly suitable for oil-free, high temperature, high load, low speed, anti-fouling, corrosion, strong radiation environment, and In the water or other solution moisture and the foundation can not add smooth grease under the special conditions of use.
2, since the optical block area than the number of self-light block surface area with the working speed, pressure strength, low speed; pressure strength, metal area should be larger. Such as grasping the ingot car travel roller bearing area occupied by the optical block is about 25%, the spindles of the shaft bearings to be smooth and smooth, the pressure is not strong, since the optical block occupied area of ​​about 65%.
