摘　　要：通过对平衡式低脉动多齿轮马达的扭矩特性的分析和仿真研究 ,得到了如下结论 :当径向齿轮的个数为 4 ,中心轮和径向齿轮的齿数相同 ,均为 4k± 1,且对称布置时 ,该马达的扭矩脉动只有普通齿轮马达的 1 16 ,扭矩脉动频率是普通齿轮马达的 4倍 ,机械特性得到明显改善 ,具有运行平稳、噪声低的特点 。By the analyzing and simulating of the flow characteristic to the multi-gear pump, we can get some conclusions .At the condition that the number of the radial gear is four, and the center gear is the same as the radial gear, and the number of the gear tooth is 4k±torq1, and the radial gear is symmetry as fig1, the flow pulsation rate of the pump is only one 1/16 of the general gear pump, and the pulsation frequency of the pump is four times of the general gear pump. The flow character of the pump is better than the general one. The pump has some good characters such as calmly running and little noise. It can be widely used in high hydraulic pressure system.
