技术领域
本发明涉及液压传动技术领域，特别涉及一种液压能向机械能转换的摆线液压马达，以及一种摆线液压马达中配流支撑板的制造方法。
背景技术
摆线液压马达是常用的液压驱动装置，是一种低速大扭矩马达，具有体积小、单位功率密度大、效率高、转速范围宽等优点，得到了广泛应用，而随着工农业发展水平提高应用将更加广泛。
此类装置的基本结构是体壳或后盖上制有进液口和回流口，一端装有摆线针轮啮合副和配流机构，配流机构可以放置在摆线针轮啮合副前或后，一般在前(体壳一侧)为轴阀配流，在后(后盖一侧)为平面配流，另一端装有输出轴。摆线针轮啮合副的转子通过内花键与联动轴一端的外齿轮啮合，联动轴的另一端与输出轴传动衔接。工作时，配流机构使进液口与摆线针轮副的扩展啮合腔连通，并使摆线针轮副的收缩腔与回流口连通。结果，压力液体从进液口进入体壳或后盖后，进入摆线针轮啮合副形成的扩展啮合腔，使其容积不断扩大，同时摆线针轮啮合副形成的收缩啮合腔中液体则从回流口回流；在此过程中，摆线针轮啮合副的转子被扩展啮合腔与收缩啮合腔的压力差驱使旋转，并将此转动通过联动轴传递到输出轴输出，从而实现液压能向机械能的转换。与此同时，配流机构也被联动轴带动旋转，周而复始的不断切换连通状态，使转换过程得以延续下去。这样，马达就可以连续的输出扭矩，可以说摆线针轮啮合副以及配流机构是液压马达的核心。
