凸轮转子叶片泵转子凸轮最佳过渡曲线的研究

Research on optimal transition curve of rotor cam in cam rotor vane pump

本文分析了凸轮转子叶片泵转子凸轮原有各种过渡曲线存在的问题，研究出一种新型过渡曲线，不但可满足泵的输出流量无脉动，而且可满足叶片运动的速度、加速度和加速度变化率均无突变（而且最大加速度值较小）的双重要求，从而可进一步降低泵的噪声、提高泵的工作性能和使用寿命。

This paper analyzes problems existed in various transition curves of rotor cam in cam rotor vane pump,and gives a new transition curve,which can satisfy output flow non-pulsated of the pump and velocity,acceleration,rate of change in acceleration,of vane movement non-mutating,and thus further decrease the noise of the pump,raises working performance and extends service life.
