    摘要:

    以橡塑复合材料为基体,将纳米和普通二硫化钼添加到基体材料中,制备一种水润滑橡塑复合尾轴承材料。通过试验探究复合轴承材料在不同载荷和转速下的摩擦磨损性能。试验结果表明:在相同载荷下,复合材料摩擦因数随着转速的升高先逐渐降低并最终趋于稳定,在相同转速下,复合材料摩擦因数随着载荷的升高而逐渐降低;复合材料摩擦因数随着二硫化钼添加量的增加先降低后升高,且纳米复合轴承材料的摩擦因数都要低于普通复合材料;二硫化钼改善了材料的摩擦性能,但没有改善材料的耐磨性;改性复合材料的磨损形式属于黏着和磨粒磨损。

    Abstract:

    A new type of water lubricated Rubber/Plastics composite bearing material was prepared by adding nanometer and ordinary molybdenum disulfide to the matrix material with different additions.The friction and wear properties of the composite material were tested by experiments at different load and speed.The results show that under the same load,the friction coefficient of the composite material is decreased gradually and eventually tend to be stable with the increasing of the relative rotational speed.Under the same speed,the friction coefficient is decreased with the increasing of the load.With the increasing of the amount of molybdenum disulfide,the friction coefficient of the material is decreased,and the nanomaterial has lower friction coefficient than the ordinary micron material.Molybdenum disulfide additive improves the friction property of the composite material,but does not improve the antiwear property of the composite material.The wear form of the modified composite material is adhesive wear and abrasive wear.
