Structure of the bearing Self-smooth bearing is developed on the metal conflict surface of the bearing base to arrange holes of appropriate size and order, and embed molybdenum disulfide and graphite to make a composite self-lighting slider inlaid on a metal sleeve. The friction area of bearings and solid smoothing agents is 25-65%. The solid self-lighting slider can work normally at a high temperature of 280 ° C. However, due to its low mechanical strength, the bearing capacity is weak, and it is easy to deform. When it is embedded in the metal hole, the defect can be pressed. The metal part plays the role of bearing and the smooth slider plays the role of smoothness.
The smoothing mechanism of this self-smooth bearing is that during the sliding conflict between the shaft and the sleeve, a part of the self-smoothing data molecules is transferred to the metal surface of the shaft, filling out small uneven surfaces, and forming a relatively stable solid smooth film. To form a pair of solid smooth films, to prevent the abrasion between the shaft and the sleeve. This reasonable connection summarizes the complementary advantages of copper alloys and non-metal antifriction materials, which are particularly suitable for motionless environments in oil-free, high temperature, high load, low speed, antifouling, corrosion, and strong radiation environments, and It can be used under the special working conditions that the water or other solution is infiltrated and the substrate cannot be added with smooth grease.
