摘要/Abstract

摘要： 为研究低速重载条件下球面摩擦副在镶嵌润滑条件下，固体润滑剂性能、镶嵌孔形状对其摩擦性能的影响，首先采用石墨与酚醛树脂混合制备了多种固体润滑剂，测试得到其力学性能测试及摩擦性能作为理论算依据；然后以三峡大坝人字闸门实际运转情况为理论依据，以相等接触面积为准则，构建了圆柱形、圆锥形、四角锥形及球冠形4种镶嵌孔形状的轴瓦，计算得到球面摩擦副静态和动态下应力-应变情况，以此得到大型球面摩擦副的理论摩擦因数；再以1:20比例尺加工得到不同镶嵌孔形状球面摩擦副试样，开展摩擦磨损试验。结果表明，试验得到的平均摩擦因数与理论值较为吻合，且在相同的石墨镶嵌润滑条件下,圆柱形镶嵌孔轴瓦的摩擦因数最低，研究结果为后续镶嵌润滑结构摩擦因数的预测提供了理论指导。

Abstract: In order to study the influence of solid lubricant performance and inlay hole shape on the friction performance of the spherical friction pair under low-speed and heavy-load conditions under inlay lubrication conditions, a variety of solid lubricants were firstly prepared by mixing graphite and phenolic resin, and tested to obtain their mechanical properties and friction performance as a basis for theoretical calculations; and then, with the actual operation of the herringbone gates of the Three Gorges Dam as a theoretical basis, and with the criterion of equal contact area, we constructed four types of cylindrical, conical, quadrangular conical and spherical crown shaped axle tiles. Then, based on the theoretical basis of the actual operation of the Three Gorges Dam, and with the criterion of equal contact area, we constructed four kinds of inlaid hole shapes of cylindrical, conical, quadrangular conical and spherical crown shaped axial shingles, and calculated the static and dynamic stress-strain conditions of the spherical friction sub, so as to obtain the theoretical friction coefficients of the large-scale spherical friction sub. The results show that the average coefficient of friction obtained from the test is more consistent with the theoretical value, and under the same graphite inlay lubrication conditions, the coefficient of friction of the cylindrical inlaid hole axial tile is the lowest, and the results of the study provide theoretical guidance for the prediction of the coefficient of friction of the subsequent inlaid lubrication structure.
