摘　　要：研究了大功率调速型液力偶合器调速控制系统,指出调速特性曲线线性化的重要性。建立了速比—勺管位移—工作油量—进油口面积的数学模型,得出了速比—工作油流量—进油口面积的对应关系并绘出变化曲线。给出了一种进出口复合调节调速系统的设计方法,介绍了阀芯进油口形状和勺管上沟槽形状的设计方法。The speed eontrol system for high power variable speed hydraulic coupling is studied, and the importance of the speed regulation characteristic linearization is pointed out. The mathematical model of speed ratio, the displacement of scoop tube, working oil and inlet area is set up, and the corresponding relation of speed ratio, working oil and inlet area is obtained. A design method of inlet ＆ outlet compound regulating speed system is given, and the design method of oil inlet shape of valve and groove shape of scoop tube are introduced.
