摘　　要：在分析内啮合齿轮泵径向补偿月牙块工作原理的基础上对其建模,分析了上下月牙块在内外齿轮运行过程中的受力情况和液压力变化周期,确定一个周期内不同位置时上下月牙块所受油压分布以及其x、y方向液压力,得到了使上下月牙块合力最大时的内外齿轮转角和使两月牙块分别贴紧内外齿轮齿顶形成径向密封的情况下的约束条件,在此基础上优化得到上下月牙块对内外齿轮压力最小时上月牙块在高压区的端面角度和密封小棒安装角度参数。The working mechanism of the stationary crescent for radial compensation of the inner mesh gear pumps is studied and the model was established.Then the force of the above and below stationary crescent during the process of operation and the changing cycle of hydraulic pressure are analyzed.The distribution of pressure on the above and below stationary crescent in different positions and the hydraulic force at the x、y direction are determined.The rotational angle of the maximal force of the above and below stationary crescent and the constraint conditions of the two stationary crescents stay close to the crest of inner gear and external gear to form radial seal are obtained.The angle of the end of the above stationary crescent in the high pressure area and the fixing angle of the seal stick of the least resultant force is calculated by optimization.
