摘　　要：为改善转子式容积泵存在的排量小、压力脉动较大、径向力不平衡等问题,提出新型转动导杆-齿轮驱动式叶片差速泵,分析以曲柄为主动件和以导杆为主动件的叶片差速泵转动导杆-齿轮驱动系统,研究转动导杆-齿轮驱动系统的运动特征及其随运动特征系数变化的运动规律.在此基础上分别建立两种驱动系统的基本参数方程,对比分析两种驱动系统下叶片差速泵的运动特性和力学特性.研究表明,以导杆为主动件的转动导杆-齿轮机构组合的叶片差速泵驱动系统更具优越性.To overcome the drawback of small displacement, large pressure fluctuation and unbalanced radial force of a rotary positive displacement pump, the rotating-guide-bar and gear mechanisms assembled driving systems of differential velocity vane pump with the cranks and the guide-bars as active parts are ＇presented in this paper. With variation of the motion characteristic coefficient on the rotating-guide-bar and gear mecha- nisms assembled driving systems, their motion characteristics and laws are investigatedl The basic parameter equations are established and the kinematics characteristics and mechanics performance are analyzed for these two types of driving systems. The results show that the transmission performance of rotating-guide-bar and gear mechanisms assembled driving system with the guide-bars as active parts is superior to that with cranks as ac- tive parts.
