轴向柱塞泵配流副低压区织构化试验研究

摘要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．

Study on tribological performance of textured port plates of axial piston pumps

In order to investigate the friction and wear performance of port plate pair textured in the low pressure area,a kind of friction and wear testing machine for port plate pair was developed.Friction and wear of port plate pair with many different textured parameters were tested and compared to results of untextured port plate pair.The results show that the port plate pair which is textured in the low pressure area can effectively reduce the friction coefficient,the friction reduction ratio can reach 29.11% at max.Textured port plate pair′s average wear volume is much less exposed to the untextured port plate pair.Untextured port plate pair reduces eccentric wear and has a more uniform wear surface.The elementary experiment shows that the average wear volume is sensitive to the area ratio and diameter of micro-pits,the minimum average wear occurs at the range of 100～200 μm.
