为研究低压区织构化轴向柱塞泵配流副的摩擦磨损性能,设计了配流副的摩擦磨损试验机,对织构化配流副进行了试验研究,并与无织构配流副的摩擦磨损情况进行对比.研究结果表明:低压区织构化的配流副能够有效减小摩擦系数,最大减摩率可达29.11%;低压区织构化的配流副比无织构的平均磨损体积要小,且整个摩擦面磨损较为均匀,降低了配流副的偏磨.初步磨损试验表明:平均磨损体积量对表面织构面积率和直径较为敏感,最小平均磨损体积量出现在微凹坑直径100～200μm范围内.
In order to study the friction and wear properties of the axial piston pump with low pressure zone, a friction and wear testing machine with a flow distribution pair was designed. The experimental study of the texture distribution and flow pair was carried out. The friction and wear properties The results show that: the low pressure area weaved pair can effectively reduce the friction coefficient, the maximum friction reduction rate of up to 29.11%; low pressure zone texture of the distribution of the flow than the average wear volume of non-textured smaller , And the wear of the entire friction surface is more uniform, which reduces the partial wear of the couple.Preliminary wear tests show that the average wear volume is sensitive to the surface texture area ratio and diameter, the minimum average wear volume appears in the dimple diameter of 100 ~ 200μm.
