Study on Oil Circuit Control System of Large-scale Gear Variable Speed Device

针对大型复合调节式齿轮调速装置,研究了勺管位移——工作腔进油——勺管体排油控制系统,推导了调速装置工作腔工作油量计算公式。以某大型齿轮调速装置为例,计算了不同速比下需要的工作油油量,得到了进油控制阀通油面积与速比的关系曲线,给出了勺管体内径计算公式,计算了不同容积率下的勺管口位置等,为大型复合式齿轮调速装置油路控制系统整体设计提供了重要依据。

Based on composite control of large scale gear variable speed device, the control system of displacement of scoop tube, inlet oil of working chamber and outlet oil of scoop tube are studied, the formula of the working oil capacity is deduced. The working oilcapaeities needed for different speed ratio are calculated, the relation curve be- tween oil passing area of the inlet oil control valve and speed ratio is obtained, a computational formula of the inner diameter of scoop tube is provided, the positions of scoop tube orifice in different volume ratio are computed. An important basis for the overall design of oil circuit control system for largescale gear valiablespeed device is provided.
