摘要

铜基固体润滑镶嵌技术广泛应用于工业生产中，尤其是在低速和重载条件下，由于接触应力的分布，填充孔隙的结构和分布对摩擦性能有显著影响。本文根据三峡闸门底部枢轴的工作条件，采用石墨作为固体填充润滑剂。在MMW-1A型润滑脂摩擦磨损试验机上，采用正交等效试验研究了填充孔径、填充孔深度和面积分布率对摩擦磨损性能的影响。结合三维形貌测试和铁谱分析，结果表明：1）三个参数对测试结果的影响为：充填孔径>面积分布率>充填孔隙深度；2）当填充孔径为3mm时，面积分布率为12%

Effect of Graphite Filling Pore Structure Size on the Tribology Behaviors of Tin Bronze/45 Steel Pairs With Grease Under Low-Speed and Heavy Load Conditions

Copper-based solid lubrication inlay technology is widely used in industrial production, especially in low-speed and heavy load conditions, and the structure and distribution of the filling pore have a significant influence on the friction performance due to the distribution of contact stress. In this paper, based on the operating conditions of the bottom pivot of the Three Gorges gate, graphite is used as a solid filled lubricant. The effects of filling pore diameter, filling pore depth, and area distribution rate on the friction and wear properties were studied by orthogonal equivalent test on MMW-1A tester with grease. Combining the three-dimensional morphology test and ferrography analysis, the results show that: 1) the influence of three parameters on the test results are: filling pore diameter > area distribution rate > filling pore depth; 2) when the filling pore diameter is 3 mm, the area distribution rate is 12%
