摘　　要：在分析内啮合齿轮泵胶合失效的基础上,设计了一种静压支撑方法。分析了内齿轮上液压力变化周期,创建了其网格模型,运用FLUENT仿真软件模拟出在一个周期内不同位置时内齿轮内壁所受油压分布以及液压力大小和方向。在此基础上,确定泵体内壁上静压支撑槽的角度范围,并比较了在开静压支撑槽前后的内齿轮受力大小。数值模拟和样机试验结果表明静压支撑方法可防止内啮合齿轮泵胶合失效。A kind of hydrostatic support method was developed based on the analysis of the failure of inner mesh gear pumps＇ agglutination in this paper.The changing cycle of pressure on the inner gear was analyzed,and the grid model was built.The distribution of pressure on the inner wall of inner gear in different positions was simulated as well as the direction and magnitude by the FLUENT software.The angle range of the hydrostatic support＇s channel on the inner wall of pump body was determined according to the above analysis and the force generated after making hydrostatic support＇s channel was compared with the one of no hydrostatic support＇s channel.The result of the numerical simulation and prototype experiment shows that the agglutination failure of inner mesh gear pumps can be avoided by hydrostatic support method.
