摘　　要：分析液压轴向柱塞泵产生工作噪声和发热以及影响使用寿命的主要因素,研究液压轴向柱塞泵配流机构在配流过程中产生压力瞬变和流量脉动以及配流噪声的机理,提出采用在高低压腰形槽的始端设置具有两种宽度夹角的双级三角阻尼槽配阻尼孔结构的设计方案,可降低噪声、减少发热,提高使用寿命。Main factors influencing the pump＇s working noise, heating and life of hydraulic axial piston pump were analyzed, and the pressure transient, flow pulsation, mechanism of distribution noise caused by distribution process were studied. The paper puts forward the designing project with tow-breadth inclination two-stage triangle damping groove and damping hole in the start bit of high-low pressure kidney groove in an attempt to reduce noise, avoid over-hearing and extend service life.
