【中文摘要】 提出了一种新型齿轮泵—平衡式复合齿轮泵,它保留了普通齿轮泵的优点,而且结构新颖、原理先进。 建立了平衡式复合齿轮泵的基本理论,介绍了该泵的工作原理,确定了配流结构,设计了变量系统,并通过数学推理,证明了齿轮上的液压力是平衡的。 研究了平衡式复合齿轮泵的流量特性,给出了瞬态流量公式及流量脉动计算式。研究结果表明,平衡式复合齿轮泵的流量脉动较普通齿轮泵要小得多。 建立了平衡式复合齿轮泵优化设计数学模型,选择了优化方法,编制了优化程序,得出了优化结果。 进行了复合齿轮泵样机的制作及试验研究,试验结果表明,该泵具有良好的流量均匀性。

【英文摘要】 A new type of gear pump — balanced compound gear pump has been presented. The pump maintains the advantages of a conventional gear pump.This dissertation built the basic theory of the pump, which introduced its working principle, determined its distribution structure, designed its flow varying systems, and then it proved that the hydraulic pressure is totally balanced by means.of strict mathematical deduction.This paper investigated the flow characteristics of the pump, deduced the equation of the instantaneous flow and the pulsation of the pump. The result is that the flow pulsation of the pump is far smaller than that of the same type.In this dissertation, the author built a mathematical model of mechanical optimization. A universal program was designed and the result of optimization of the pump was obtained.On the base of optimization, the author designed the pump model. After experimental study, the conclusion was obtained that the balanced compound gear pump has good flow characte...更多ristics.  还原
